*Gene gymnastics*: *Synthetic biology for baculovirus expression vector system engineering*

by
Vijayachandran LS, Thimiri Govinda Raj DB, Edelweiss E, Gupta K, Maier J, Gordeliy V, Fitzgerald DJ, Berger I.

"Most essential activities in eukaryotic cells are catalyzed by large multiprotein assemblies containing up to ten or more interlocking subunits. The vast majority of these protein complexes are not easily accessible for high resolution studies aimed at unlocking their mechanisms, due to their low cellular abundance and high heterogeneity. Recombinant overproduction can resolve this bottleneck and baculovirus expression vector systems (BEVS) have emerged as particularly powerful tools for the provision of eukaryotic multiprotein complexes in high quality and quantity. Recently, synthetic biology approaches have begun to make their mark in improving existing BEVS reagents by de novo design of streamlined transfer plasmids and by engineering the baculovirus genome. Here we present OmniBac, comprising new custom designed reagents that further facilitate the integration of heterologous genes into the baculovirus genome for multiprotein expression. Based on comparative genome analysis and data mining, we herein present a blueprint to custom design and engineer the entire baculovirus genome for optimized production properties using a bottom-up synthetic biology approach."

Wanted: Surrogate for Neanderthal Baby

Gerd Moe-Behrens's insight:


*Wanted: Surrogate for Neanderthal Baby*

by
Susan Young

"GenomeWeb caught what must be an interesting Q&A with George Church in Germany’s Spiegel Online (I can’t personally attest to the original story as it is behind a paywall). The Harvard Medical School geneticist is quoted as saying that eventually, an “adventurous female human” will be needed to be the surrogate mother for the first Neanderthal baby in some 30,000 years.

 This isn’t the first time Church has talked publically about cloning a Neanderthal, or at least a near-Neanderthal. In 2009, when the Neanderthal genome was first reported, the New York Times described a scenario in which a current day human genome could be tweaked into the “Neanderthal equivalent” with tools of molecular biology. Eventually, this could lead to a Neanderthal-like embryo in need of a surrogate mother. While the idea of reviving Neanderthals may sound farfetched, take for example the work of biologists to clone endangered or extinct non-human animals (see “Stem-Cell Engineering Offers a Lifeline to Endangered Species”). In 2009, the extinct bucardo, a subspecies Spanish ibex, was cloned from a frozen skin sample. The newborn died immediately due to respiratory failure, but its birth suggests that resurrecting extinct species may be possible."

*Interview with George Church*: *Can Neanderthals Be Brought Back from the Dead*? 

"In a SPIEGEL interview, synthetic biology expert George Church of Harvard University explains how DNA will become the building material of the future -- one that can help create virus-resistant human beings and possibly bring back lost species like the Neanderthal.
George Church, 58, is a pioneer in synthetic biology, a field whose aim is to create synthetic DNA and organisms in the laboratory. During the 1980s, the Harvard University professor of genetics helped initiate the Human Genome Project that created a map of the human genome. In addition to his current work in developing accelerated procedures for sequencing and synthesizing DNA, he has also been involved in the establishing of around two dozen biotech firms. In his new book, "Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves," which he has also encoded as strands of DNA and distributed on small DNA chips, Church sketches out a story of a second, man-made Creation.
SPIEGEL recently sat down with Church to discuss his new tome and the prospects for using synthetic biology to bring the Neanderthal back from exctinction as well as the idea of making humans resistant to all viruses.

SPIEGEL: Mr. Church, you predict that it will soon be possible to clone Neanderthals. What do you mean by "soon"? Will you witness the birth of a Neanderthal baby in your lifetime?Church: That depends on a hell of a lot of things, but I think so. The reason I would consider it a possibility is that a bunch of technologies are developing faster than ever before. In particular, reading and writing DNA is now about a million times faster than seven or eight years ago. Another technology that the de-extinction of a Neanderthal would require is human cloning. We can clone all kinds of mammals, so it's very likely that we could clone a human. Why shouldn't we be able to do so? SPIEGEL: Perhaps because it is banned? Church: That may be true in Germany, but it's not banned all over the world. And laws can change, by the way. SPIEGEL: Would cloning a Neanderthal be a desirable thing to do? Church: Well, that's another thing. I tend to decide on what is desirable based on societal consensus. My role is to determine what's technologically feasible. All I can do is reduce the risk and increase the benefits. SPIEGEL: So let's talk about possible benefits of a Neanderthal in this world. Church: Well, Neanderthals might think differently than we do. We know that they had a larger cranial size. They could even be more intelligent than us. When the time comes to deal with an epidemic or getting off the planet or whatever, it's conceivable that their way of thinking could be beneficial....."

Gerd Moe-Behrens's insight:

"Designed self-assembled DNA crystals consist of rigid DNA motifs that are held together by cohesive sticky-ended interactions. A prominent application of such systems is that they might be able to act as macromolecular hosts for macromolecular guests, thereby alleviating the crystallization problem of structural biology. We have recently demonstrated that it is indeed possible to design and construct such crystals and to determine their structures by X-ray diffraction procedures. To act as useful hosts that organize biological macromolecules for crystallographic purposes, maximizing the resolution of the crystals will maximize the utility of the approach. The structures reported so far have diffracted only to about 4 Å, so we have examined two factors that might have impact on the resolution. We find no difference in the resolution whether the DNA is synthetic or PCR-generated. However, we find that the presence of a phosphate on the 5' end of the strands improves the resolution of the crystals markedly."

The state of the art in biomimetics

The state of the art in biomimetics | SynBioFromLeukipposInstitute | Scoop.it
Gerd Moe-Behrens's insight:

by
Lepora NF, Verschure P, Prescott TJ.

"Biomimetics is a research field that is achieving particular prominence through an explosion of new discoveries in biology and engineering. The field concerns novel technologies developed through the transfer of function from biological systems. To analyze the impact of this field within engineering and related sciences, we compiled an extensive database of publications for study with network-based information analysis techniques. Criteria included publications by year and journal or conference, and subject areas judged by popular and common terms in titles. Our results reveal that this research area has expanded rapidly from less than 100 papers per year in the 1990s to several thousand papers per year in the first decade of this century. Moreover, this research is having impact across a variety of research themes, spanning robotics, computer science and bioengineering. In consequence, biomimetics is becoming a leading paradigm for the development of new technologies that will potentially lead to significant scientific, societal and economic impact in the near future."

"Want to keep track of every piece of personal data in your life? There's probably a tool for you.

If you want something done, do it yourself, the old saying goes. It's a philosophy that fuels the "quantified self," a growing movement toward tracking one's life with the help of technology. It extends far beyond Nike's (NKE) groundbreaking Nike+ running app: Devotees can dutifully track fitness routines, eating habits, even medical conditions. And companies are developing tools for nearly every scenario imaginable. Here are just a few.FitnessRunKeeper employs a phone's GPS to track activities like running and cycling, and through its Health Graph lets users compare performance. Devices like the Fitbit apply a data-tracking method called actigraphy to gauge movements during sleep.MedicineThe Spiroscout sensor, an inhaler attachment, uses satellite data to show asthmatics locations that may worsen their condition. The Boozerlyzer, built to measure blood alcohol levels, can be doctored to track drug intake and side effects.LifestyleWith GreenGoose's sticker-size sensors, everyday items  -- toothbrushes, toys, even pets -- transmit data back to an egg-shaped base station. Users can keep track of information such as how often they've brushed their teeth or if someone walked the dog...."

"World's FIRST citizen science project to sequence the human microbiome. Available INTERNATIONALLY in 196 countries. Learn about your health & change the world!

Scientists recently discovered an important new organ in the human body. Incredibly, this organ isn’t made of human cells: It’s microbes! In fact, there are so many of these microbes in your body that they outnumber human cells 10 to 1. This is your microbiome. It's another world inside your body. Thousands of species, trillions and trillions of tiny organisms. We barely know who they are, let alone what they're doing -- or importantly, how they affect our health. It's been described as the greatest scientific mystery of our day.  By joining uBiome, you can explore your own microbiome and participate in the exciting scientific discovery to unlock this mystery. In order for it to work, we need lots of samples and a little bit of money. By pulling together as a group, we can do cutting-edge biomedical research at a fraction of the normal cost. It's called citizen science."

Bacillus subtilis: from soil bacterium to super-secreting cell factory

Bacillus subtilis: from soil bacterium to super-secreting cell factory | SynBioFromLeukipposInstitute | Scoop.it
Gerd Moe-Behrens's insight:

by

Jan Maarten van Dijl and Michael Hecker
"The biotechnology industry has become a key element in modern societies. Within this industry, the production of recombinant enzymes and biopharmaceutical proteins is of major importance. The global markets for such recombinant proteins are growing rapidly and, accordingly, there is a continuous need for new production platforms that can deliver protein products in greater yields, with higher quality and at lower costs. This calls for the development of next-generation super-secreting cell factories. One of the microbial cell factories that can meet these challenges is the Gram-positive bacterium Bacillus subtilis, an inhabitant of the upper layers of the soil that has the capacity to secrete proteins in the gram per litre range. The engineering of B. subtilis into a next-generation super-secreting cell factory requires combined Systems and Synthetic Biology approaches. In this way, the bacterial protein secretion machinery can be optimized from the single molecule to the network level while, at the same time, taking into account the balanced use of cellular resources. Although highly ambitious, this is an achievable objective due to recent advances in functional genomics and Systems- and Synthetic Biological analyses of B. subtilis cells."

*The One and Only Popular Synthetic Biology Book*

by
Eric Sawyer

"Three months ago, the first popular synthetic biology book was released. Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves is the work of Harvard biologist George Church and science writer Ed Regis, who team up to tell the story of life on Earth and speculate about the roles technologies like synthetic biology might play in its narrative. I had the pleasure of reading it over my winter holiday.

 Each chapter carries the name of a stretch of geological time, which serves as a jumping off point for the contents. Of particular intrigue are the recurring ideas that humans can (and in his view should) alter the biochemistry of our industrial microbes, and eventually ourselves. The simplest approach to this would be to tweak the genetic code, which dictates how sequences of nucleotides (A, C, G, T/U) in DNA and RNA are translated into the set of 20 amino acids used in proteins. Viruses, whether they are human pathogens or E. coli pathogens, take over their hosts by exploiting the universality of the code. Tweaking the code or making a new one entirely would bestow total invulnerability to viral infection. To my surprise, we actually have a lot of the pieces needed to accomplish this, though putting them together is another matter. The potential of genome-wide engineering extends beyond viral resistance. Church offers them as a practical alternative to the whole genome synthesis approach of the J. Craig Venter Institute: one genome could be evolved into another in the laboratory. This could mean introducing exotic genes that make humans a hardier species, perhaps for safer space travel. And, he suggests, extinct species with surviving DNA but no surviving cells could be resurrected from living relatives, perhaps avoiding ecosystem collapses. Church also proposes using this technology to bring back the Neanderthals, with the stated goal of bringing more genetic diversity into the human gene pool. However, it's not entirely clear why he specifically suggests this, since diversity presumably could be introduced into humans directly without the need of the Neanderthals. Nevertheless, perhaps human society would benefit from a relaxed self-importance that would likely result from the reawakening of the Neanderthals...."

*The Growing Pains and Pleasures of a Synthetic Biology Start-Up* 

BY JEFFREY MARLOW

"On the southeastern outskirts of Denver, Colorado, where snow-dusted prairie meets freshly laid asphalt and barbed wire fences restrain the tumbleweed, a nondescript office building in a business park houses Gevo.  From these innocuous facilities – and a growing number of production plants and test sites around the world – the fledgling biotech company is reimagining a handful of industries from plastic bottle production to renewable fuels.

 The common link in Gevo’s ambitious reach is isobutanol, a four-carbon alcohol packed with energetic potential and useful for several industrial applications.  The company’s primary thrust – and most far-reaching opportunity – is the integration of isobutanol into the fuel industry, which could provide a continuous bridge (isobutanol works as a gasoline additive and is compatible with existing infrastructure) toward renewable fuels. Gevo was founded by Frances Arnold, the Caltech professor who employs directed evolution to improve target enzymes, co-opting biological machinery for industrial purposes.  The original goal was to produce methanol from methane, but as Gevo President and Chief Operating Officer Chris Ryan puts it, “technologically it was a very challenging problem.”  Arnold’s researchers couldn’t get the methane processing enzymes to behave no matter how much they altered the underlying amino acid code.  This technical roadblock, along with the fact that methanol has questionable profitability margins, led the fledgling company to pursue isobutanol instead...."

By
Anthony C. Forster

"Synthetic biology is a powerful experimental approach, not only for developing new biotechnology applications, but also for testing hypotheses in basic biological science. Here, examples from our research using the best model system, Escherichia coli, are reviewed. New evidence drawn from synthetic biology has overturned several long-standing hypotheses regarding the mechanisms of transcription and translation: (i) all native aminoacyl-tRNAs are not equally efficient in translation at equivalent concentrations; (ii) accommodation is not always rate limiting in translation, and may not be for any aminoacyl-tRNA; (iii) proline is the only N-alkyl-amino acid in the genetic code not because of special suitability for protein structure, but because of its comparatively high nucleophilicity; (iv) the usages of most sense codons in E. coli do not correlate with cognate tRNA abundances and (v) class II transcriptional pausing and termination by T7 RNA polymerase cannot be assumed to occur in vivo based on in vitro data. Implications of these conclusions for the biotechnology field are discussed."

by
+Eugenio Battaglia 

"I'm totally supporting this potential system theorized some days ago by Micah Allen and his friend Hauke on Allen's Neuroconscience blog . They discuss a quick and reliable strategy to share papers behind a paywall.

The proposed system is really easy and accessible by everyone, since it uses particular twitter's #hashtags for query and response.I strongly believe that what started after Aaron Swartz's dead with #pdftribute, and continued with #sharecredentials (unfortunately and strangely still not so shared on twitter), and now followed by #icanhazpdf / #papester  will quickly lead to a massive weaken of paywall systems. Therefore, this will push people to understand and to propose alternative ways that are more ethically correct and also apt to current science needs.  Also, i don't believe that this ways are so illegal to warn people not to use them, and even if they are is just because old rules simply doesn't fit anymore with the actual need of a more open and accessible science. Finally, i could suggest you to leave the army and join the pirates! Because no one will be interested in fighting for your right of research. We are facing really big issues nowadays, and without a coordinated network strategy we won't be able to solve this topics together. Instead we would leave this solutions to big institutions and corporations, that to this date are too biased by market logics and profitable goals.Concluding, i think this battle has to be fight by those who believe that knowledge has to be definitely accessible to everyone on Earth. I don't want to necessarily appear as a criminal, and of course I'm aware that editors have to make profits in order to produce a quality service, but the results of paywalls are pretty clear. A recent article on Cyberpsychology, behavior and social networking journal, argue:"In a national online longitudinal survey, participants reported their attitudes and behaviors in response to the recently implemented metered paywall by the New York Times. Previously free online content now requires a digital subscription to access beyond a small free monthly allotment. Participants were surveyed shortly after the paywall was announced and again 11 weeks after it was implemented to understand how they would react and adapt to this change. Most readers planned not to pay and ultimately did not. Instead, they devalued the newspaper, visited its Web site less frequently, and used loopholes, particularly those who thought the paywall would lead to inequality."[1]Finally, I want share the interesting idea of Allen and his friend Hauke:"Yesterday my friend Hauke and I theorized about a kind of dream scenario- a totally distributed, easy to use, publication liberation system. This is perhaps not feasible at this point [1]. Today we’re going to present something that will be useful right now. The essential goal here is to make it so that anyone, anywhere, can access the papers they need in a timely manner. The idea is to take advantage of existing strategies and tools to streamline paper sharing as much as possible. Folks already do this- every day on twitter or in private, requests for papers are made and fulfilled. Our goal is to completely streamline this process down to a few clicks of your mouse. That way a small but dedicated group of folks – the Papester Collective – can ensure that #icanhazpdf requests are fulfilled almost instantly. This is a work in progress. Leave comments on how to improve and further streamline this system and join the collective!  SHORT VERSION: HOW TO GET A PAPER BEHIND A PAYWALL QUICKLY Tweet (for example): “#icanhazpdf http://dx.doi.org/10.1523/JNEUROSCI.4568-12.2013” Show your support for the papester collective by tweeting: “Thanks to #papester, my #icanhazpdf request was fufilled in seconds!

Now you can just click request links, click the Zotero get PDF button, and CTRL+V a dropbox direct download link in response! Click: Here you can find more detailed instructions.  1.The fundamental problem: uploading huge repositories of scientific papers is not sensible for now. It’s too much data (50 million papers * 0.5-1.5 megabytes together make up ~ 25-75 Terrabytes) and the likelihood for every paper to be downloaded is more uniformly distributed than with files traditionally shared like music. For instance, there are 100 million songs x 3.5 mb songs, and it is difficult to find exotic songs online – some songs have decent availability now because there are only a few favourites – not so with favourite papers. Also, fewer people will share papers than songs, so this makes it more even more difficult to sustain a complete repository. Thus, we need a system that fufills requests individually. Disclaimer: Please make sure you only share papers with friends who also have the copyrights to the papers you share." From Michah Allen's Neuroscience BlogAs you can see I reported the disclaimer of Allen's Blog.

*Identifying Personal Genomes by Surname Inference*

by
Melissa Gymrek, Amy L. McGuire, David Golan, Eran Halperin, Yaniv Erlich

"Sharing sequencing data sets without identifiers has become a common practice in genomics. Here, we report that surnames can be recovered from personal genomes by profiling short tandem repeats on the Y chromosome (Y-STRs) and querying recreational genetic genealogy databases. We show that a combination of a surname with other types of metadata, such as age and state, can be used to triangulate the identity of the target. A key feature of this technique is that it entirely relies on free, publicly accessible Internet resources. We quantitatively analyze the probability of identification for U.S. males. We further demonstrate the feasibility of this technique by tracing back with high probability the identities of multiple participants in public sequencing projects."

That’s one goal of synthetic biology, a field that was catapulted into the news last week with the announcement that a group of biologists had manufactured a genome that exists nowhere in nature and inserted it into a bacterial cell. The dream is that, one day, we’ll be able to sit and think about what sort of life-form we’d like to make — and then design and build it in much the same way we make a bridge or a car.

 Realizing this dream is still some way off. But before I get to that, let me briefly describe the state of play. Synthetic biology is predicated on the fact that, to a large extent, organisms can be broken down into a set of parts. For example, the information contained in DNA comes in discrete chunks — namely, genes. Genes contain the instructions for making proteins — molecules that come in different shapes and sizes — as well as information about where and when those proteins should be used. Proteins interact with each other, driving many of the functions of the cell. Some genes are essential: without the proteins they encode, the organism cannot exist. But many genes are “optional” — in the laboratory at least, the organism gets on fine without them.  Likewise, having an “extra” gene or two isn’t usually a problem. Already, we have exploited this fact to insert new genes into organisms as diverse as petunias and goats. Since the 1980s, human insulin has been mass-produced by bacterial cells genetically engineered to make it....."

Perspective: Nanomotors without moving parts that propel themselves in solution

Perspective: Nanomotors without moving parts that propel themselves in solution | SynBioFromLeukipposInstitute | Scoop.it
Gerd Moe-Behrens's insight:

by
Raymond Kapral

"Self-propelled nanomotors use chemical energy to produce directed motion. Like many molecular motors they suffer strong perturbations from the environment in which they move as a result of thermal fluctuations and do not rely on inertia for their propulsion. Such tiny motors are the subject of considerable research because of their potential applications, and a variety of synthetic motors have been made and are being studied for this purpose. Chemically powered self-propelled nanomotors without moving parts that rely on asymmetric chemical reactions to effect directed motion are the focus of this article. The mechanisms they use for propulsion, how size and fuel sources influence their motion, how they cope with strong molecular fluctuations, and how they behave collectively are described. The practical applications of such nanomotors are largely unrealized and the subject of speculation. Since molecular motors are ubiquitous in biology and perform a myriad of complex tasks, the hope is that synthetic motors might be able to perform analogous tasks. They may have the potential to change our perspective on how chemical dynamics takes place in complex systems."

The 10 Tech Terms to Know in 2013

The 10 Tech Terms to Know in 2013 | SynBioFromLeukipposInstitute | Scoop.it
Gerd Moe-Behrens's insight:

by
RACHEL Z. ARNDT

I"n 2013 we will sequence DNA faster and cheaper than ever, design radios that intelligently find open spectrum amid the crowded airways, and charge EVs without plugging them in. Consider this your cheat sheet for the year in tech.
*Nanopore Sequencing*
Back in 2008 it took four months and nearly $1.5 million to sequence the complete genome of DNA co-discoverer James Watson. Now, with the commercialization of nanopore sequencing on the horizon, it should take only 15 minutes. Decoding a genome requires linking together several of Oxford Nanopore Technologies' $30,000 sequencers. Each sequencer pulls a strand of DNA through a 1-nanometer—wide hole—about 100,000 times smaller than the diameter of a human hair—and monitors the distinctive changes in an electric current that reveal which of the four DNA bases is passing through the opening. Oxford Nanopore Technologies is also releasing a single-use sequencer that plugs into a computer like a USB key and costs less than $900....."

"Researchers are injecting ever more conscious design into their bioengineering workflow.

Yogurt. Comedian George Carlin wouldn’t touch it; Spaceballs villain “Dark Helmet” “hated” it—even with strawberries. But Boston University biomedical engineer James Collins, a Howard Hughes Medical Institute Investigator, has recently been giv- ing the fermented dairy treat a great deal of thought. Not how his preferred flavor, vanilla, tastes atop granola, nor how plain yogurt and dill pair perfectly with salmon. For Collins, yogurt—or, more precisely, the lactobacilli that make yogurt yogurt—could potentially be the answer to a vexing public health problem: cholera.Collins is a pioneer in the burgeoning field of synthetic biology, the science of reprogramming cells with novel biological functions, from biosensors to antimicrobi- als to biofuels. The field, writes Harvard Medical School geneticist George Church, capitalizes on the fact that biological organisms are effectively programmable manufacturing systems. In this context, cells serve as miniature computers, pro- grammed toward a new purpose with externally supplied genetic instructions. Church notes that “making small changes in their genetic software a bioengineer can effect big changes in their output”....."

*Biosafety Considerations of Synthetic Biology in the International Genetically Engineered Machine (iGEM) Competition

Gerd Moe-Behrens's insight:

by
Zheng-jun Guan, Markus Schmidt, Lei Pei, Wei Wei and Ke-ping Ma

"The International Genetically Engineered Machines (iGEM) competition is one of the largest and most visible activities in synthetic biology. iGEM serves to introduce synthetic biology to students—the pool of talent for the future of synthetic biology. Although its participants have tried to construct useful genetic devices and systems in a playful way, iGEM has also been recognized for its important role in raising students’ awareness of biosafety issues. In the present study, we analyzed how the iGEM teams have quantitatively and qualitatively dealt with new safety requirements in recent years and what suggestions were made to further improve biosafety. We found an increase in the number of teams reporting safety aspects and a general improvement in the safety assessment of their projects. Although the students’ safety awareness has improved, certain gaps must still be filled before iGEM can fully live up to its role as an educational competition."

Leguia M, Brophy JA, Densmore D, Asante A, Anderson JC.

" There is growing demand for robust DNA assembly strategies to quickly and accurately fabricate genetic circuits for synthetic biology. One application of this technology is reconstitution of multi-gene assemblies. Here, we integrate a new software tool chain with 2ab assembly and show that it is robust enough to generate 528 distinct composite parts with an error-free success rate of 97%. Finally, we discuss our findings in the context of its implications for biosafety and biosecurity."
