Common blood pressure medication could delay onset, or even prevent, type 1 diabetes

Common blood pressure medication could delay onset, or even prevent, type 1 diabetes | Longevity science | Scoop.it

New research into off-label uses for a 50-year-old drug commonly prescribed for high-blood pressure has found that it could prevent the onset of type 1 diabetes. The promising research also suggests a new approach for investigating drugs that could help treat a variety of autoimmune diseases.

Up to 60 percent of people at risk of developing type 1 diabetes possess a molecule dubbed DQ8. The new study, from researchers at the University of Colorado and the University of Florida, set out to investigate whether blocking that specific molecule could also block the onset of type 1 diabetes and whether there was an already approved drug that achieved this effect.

Dads could be passing on genes that advance onset of ovarian cancer

Dads could be passing on genes that advance onset of ovarian cancer | Longevity science | Scoop.it
Past studies have revealed that when a woman develops ovarian cancer, her sister has a higher risk of also developing the disease than her mother. This was difficult to explain, but researchers at the Roswell Park Comprehensive Cancer Center have discovered that a newly identified mutation on the X-chromosome, passed down from the father, may be linked to an earlier onset of ovarian cancer in women and higher rates of prostate cancer in men.

Virtual Biobank revolutionizes access to human cancer tissues

Virtual Biobank revolutionizes access to human cancer tissues | Longevity science | Scoop.it

In a move that could revolutionize the development of new cancer treatments, researchers from the University of Newcastle and the Hunter Medical Research Institute (HMRI) have created the world's first virtual platform to host 3D copies of human cancer tissues.

Until now, tissue samples donated by patients have only been available on request from physical biobanks that are based locally. The process can take a few months for clearance and the samples are usually unable to be reused once examined. As a way of improving this scenario, a team led by Dr Jamie Flynn, Dr Antony Martin and Dr William Palmer has established The Virtual Biobank.

Scientists interrupt protein partnership that helps cancer spread

Scientists interrupt protein partnership that helps cancer spread | Longevity science | Scoop.it
Transforming growth factor beta (TGF-β) is a signaling protein that normally controls the growth of healthy cells, but cancer can break the rules thanks to a mutation that allows them to spread and evade detection by the immune system. That makes TGF-β a good potential target to help combat cancer, with scientists recently engineering new T-cells to suppress the protein and track down these cloaked cancer cells.

Enzyme Plays a Key Role in Calories Burned both During Obesity and Dieting

Enzyme Plays a Key Role in Calories Burned both During Obesity and Dieting | Longevity science | Scoop.it
In a paper publishing in Cell on February 8, University of California San Diego School of Medicine researchers identify the enzyme TANK-binding kinase 1 (TBK1) as a key player in the control of energy expenditure — or calories burned — during both obesity and fasting.

“There are two important observations that we have linked to slowing metabolism in obesity and fasting,” said Saltiel. “We’ve discovered two new feedback loops that are intertwined to self-regulate the system. Think of it like your home thermostat, which senses change in temperature to turn heat off and on.”

Anti-anxiety drug found to undo some of alcohol's ill effects on the brain

Anti-anxiety drug found to undo some of alcohol's ill effects on the brain | Longevity science | Scoop.it
Researchers at the Queensland University of Technology (QUT) have discovered a surprising secondary function for an existing drug. Tandospirone is used in Japan and China to treat anxiety and depression, but now Australian researchers have found that it can "reboot" the brain to reverse some of the negative effects of heavy alcohol consumption.

Tandospirone, or Sediel as it's known commercially, is most commonly prescribed to combat generalized anxiety disorder and depression. It works by selectively acting on the serotonin receptor 5-HT1A in the brain, and according to the Japanese company that produces it, the drug is non-addictive, non-sedative, and virtually free of adverse side effects.

Food may influence cancer spread

Food may influence cancer spread | Longevity science | Scoop.it
There is mounting evidence the food on your plate can alter cancer's growth and spread, say Cambridge scientists.

Animal research, published in the journal Nature, showed breast tumours struggled without the dietary nutrient asparagine.

It is found in the foodies' favourite asparagus, as well as poultry, seafood and many other foods.

In the future, scientists hope to take advantage of cancer's "culinary addictions" to improve treatment.

Asparagine is an amino acid - a building block of protein - and takes its name from asparagus.

Mapping Brain Proteins | The Scientist Magazine®

Mapping Brain Proteins | The Scientist Magazine® | Longevity science | Scoop.it
Cellular factories perform their functions by localizing and trafficking proteins into compartments where they can serve specific purposes. Because of this, a protein’s subcellular coordinates offer valuable clues about its activities.

Scientists can visualize protein distribution within cells using super-resolution microscopy—either by tagging proteins with fluorescent probes or by using antibodies. But such methods are typically not scalable and require researchers to restrict their choice of proteins to a known set.

"Nano-factories" produce anti-cancer drugs from inside tumors

"Nano-factories" produce anti-cancer drugs from inside tumors | Longevity science | Scoop.it

Cancer cells thrive thanks to some robust defense mechanisms, so finding ways to get past them is a key area of research. In the past, scientists have sent gold nanoparticles inside tumors by hitchhiking on white blood cells, before heating the gold with near-infrared light to kill the cancer from within. Others examined the possibility of administering a "prodrug" that remained inactive until it detected cancer markers, and then began producing drugs from inside the tumor.

The new work follows a similar function as the latter. The Technion scientists loaded molecular machines inside lipid-based particles that resemble biological cell membranes, creating what they call "nano-factories." Once they're activated by sensing the presence of abnormal cells, these particles kick into gear, producing...
