Prediction of the Haa1-regulatory Network in the Oleaginous Yeast Rhodotorula toruloides

Prediction of the Haa1-regulatory Network in the Oleaginous Yeast Rhodotorula toruloides | iBB | Scoop.it

A new bioinformatics tool, developed by our computational biologist collaborators at INESC-ID, is described in a recent article published in BMC Bioinformatics. The BSRG-iBB team contributed to the application of the tool to predict the putative Haa1-regulon in the lipid producing yeast cell factory Rhodotorula toruloides. For this, genomic information on this species was collected and included in the CommunityYeastract to benefit from the access to all the comparative genomics queries offered in the YEASTRACT + portal. The transcription factor Haa1 is the main regulator of S. cerevisiae genomic response to acetic acid stress, regulating, directly or indirectly, the majority of acetic acid tolerance genes. The prediction of RtHaa1-regulon has an expected impact in the optimization of R. toruloides robustness for biorefinery processes using hydrolysates from lignocellulosic residues. The BSRG-iBB team involved in these studies included the PhD student Miguel Antunes, his supervisor Isabel Sá-Correia, and Cláudia P. Godinho and Miguel C. Teixeira.

iBB Researcher Nuno Bernardes is a Fulbright Visiting Scholar at the University of Pennsylvania | iBB | Scoop.it

In cancer cells, the glycome is distinct from that on non-cancer cells, affecting the functionality of many overexpressed membrane oncogenes. In the scope of a visit to the laboratory of Prof. Elizabeth Rhoades at the University of Pennsylvania, Nuno Bernardes from BSRG-iBB will use advanced microscopy-based biophysical approaches to determine and quantify the molecular determinants involved in protein-glycan interactions between azurin(s)-derived peptides and cancer cells. This will make use of giant plasma membrane vesicles (GPMVs) originated from cell lines and primary tumor cells. The characterization of these interactions will foster the development nano-delivery systems like nanoparticles and exosomes engineered to surface display azurins-derived peptides to improve tumor treatments. The project and visit is supported by the Fulbright program, as described here.

Lipid Hydroperoxide Compromises the Membrane Structure Organization

Lipid Hydroperoxide Compromises the Membrane Structure Organization | iBB | Scoop.it

Lipid hydroperoxides have recently been recognized as key mediators of diseases (such as neurodegenerative disorders or Type II diabetes) and cell death. In a recent work, structural and dynamic perturbations induced by the hydroperoxidized POPC lipid (POPC-OOH) in fluid POPC membranes were addressed using advanced small-angle X-ray scattering (SAXS) and fluorescence methodologies. Notably, this multidisciplinary approach revealed that the hydroperoxide group located at the membrane interface, promotes a higher membrane hydration and microviscosity, with a strikingly lower order and bending rigidity, an unusual trend in membrane biophysics, which ultimately compromises membrane structure organization. This international work co-led by Ana M. Melo (BSIRG-iBB) and Rosangela Itri (Institute of Physics, University of São Paulo) was recently published in Langmuir and involved other BSIRG-iBB researchers (Ana Coutinho, Alexander Fedorov and Manuel Prieto).

Gefitinib-Loaded p28-PLGA Nanoparticles Reduce Tumor Burden and Metastases in Lung Cancer

Gefitinib-Loaded p28-PLGA Nanoparticles Reduce Tumor Burden and Metastases in Lung Cancer | iBB | Scoop.it

p28 is a 28 amino acids peptide derived from the bacterial protein azurin. It possesses cell-penetrating capabilities showing preferential enter in cancer cells. Moreover it has been subject in US to two phase I clinical trials as a anticancer agent. In a recent paper published in Journal of Controlled Release, a iBB team (Garizo AR, Dias TP, Fernandes F, Bernardes N, Fialho AM) together with a i3S/UP team (Castro F, Martins C, Almeida A, Barrias CC, Sarmento B) were able for the first time to fabricate p28-functionalized PLGA nanoparticles (NPs) loaded with the EGFR tyrosine kinase inhibitor gefitinib. The results obtained indicate that these NPs interact preferentially with lung cancer cells due to their decoration with p28 peptide. In vitro cytotoxicity assays demonstrate biological activity of the NPs against lung cancer cancer cells. Finally, in vivo studies demonstrated a great potential of the p28-NPs in enhancing the therapeutic effects of gefitinib.

Controlling Biofilm Establishment Since the First Touch

Controlling Biofilm Establishment Since the First Touch | iBB | Scoop.it

Candida glabrata’s ability to cause human infections is tightly linked to its impressive ability to form persistent biofilms. The molecular control of this process is far from being clarified, as it lacks many of the typical features displayed by other Candida species. In this study, a combination of genetic screening, RNA-seq based transcriptomics, and Single-Cell Force Spectroscopy (SCFS), enabled the observation that the transcription factor CgEfg1, but not CgTec1, is necessary for the initial interaction of C. glabrata cells with both abiotic surfaces used in medical devices and epithelial cells, while both transcription factors orchestrate biofilm maturation. The knowledge gathered through this study by former PhD student Mafalda Cavalheiro, and an international team led by Miguel Cacho Teixeira, BSRG-iBB, including Etienne Dague, LAAS-CNRS, Geraldine Butler, University College Dublin, and Arsénio Fialho, BSRG-iBB, and just published in Communications Biology, is expected to contribute to guide the design of more successful therapeutic approaches.

Manufacture of Microfibers of Polyhydroxyalkanoate from Cassava Peel Waste by Electrospinning

Manufacture of Microfibers of Polyhydroxyalkanoate from Cassava Peel Waste by Electrospinning | iBB | Scoop.it

Cassava (Manihot esculenta) cultivation is of great importance in many economies, particularly in Colombia. About 630,000 tons of C-rich cassava waste is produced annually and applications to high value products, applying the circular economy concept, must be developed. A recent publication in Journal of Polymers and the Environment assesses the potential use of cassava peel for the production of polyhydroxyalkanoates (PHAs) by Cupriavidus necator. A copolymer of P3HB-3HV was produced and processed into electrospun meshes of random and aligned microfibers, allowing the development of structures that can be applied in the context of tissue engineering. This work involved Manuela Fonseca, Frederico Ferreita and Teresa Cesário form BERG-IBB and has been done in collaboration with researchers from the University of Antioquia, Medellin-Colombia.

Increasing Yields of Cytochrome B5 in Bioreactors

Increasing Yields of Cytochrome B5 in Bioreactors | iBB | Scoop.it

The production of recombinant proteins is gaining increasing importance as several applications request high quality proteins. However, several process parameters affect both the growth of cells and product yields. In a paper recently published in the journal Molecules, Ricardo FS Pereira and Carla CCR de Carvalho (iBB-BERG) used high throughput systems and statistical methods to assess the influence of fermentation conditions in lab-scale bioreactors. Using partial least squares, it was found that the height-to-diameter ratio of the bioreactor, aeration rate, and PID controller parameters contributed significantly to the final biomass and cytochrome concentrations. This information was used to fine-tune the process parameters, which increased cytochrome production and yield several-fold.

Adaptation to Acetic Acid Stress Involves Structural Alterations and Increased Stiffness of the Yeast Cell Wall

Adaptation to Acetic Acid Stress Involves Structural Alterations and Increased Stiffness of the Yeast Cell Wall | iBB | Scoop.it

The role of the cell wall in yeast response and tolerance to stress is frequently neglected. A BSRG-iBB research paper just published in Scientific Reports, provides, for the first time, a comprehensive view of the alterations occurring at the cell wall in a yeast population adapting to sub-lethal stress induced by acetic acid. The results reveal changes to the cell wall polysaccharide composition and nanomechanical properties, as well as alterations in the transcript levels of key cell wall biosynthetic genes. This paper reinforces the notion that the adaptive yeast response to acetic acid involves coordinated alterations of the cell wall at the biophysical and molecular levels. The gathered knowledge is important for the design of superior industrial strains and for the efficient control of the deleterious activity of spoilage yeasts, particularly in the Food Industry. This research work is first-authored by the PhD student of the PhD programme in Biotechnology and Biosciences Ricardo Ribeiro (FCT_DP AEM fellowship), performed under the supervision of Isabel Sá-Correia. This collaborative study with Fábio Fernandes (BSIRG-iBB) and Mário S. Rodrigues and his team (BioISI, Faculty of Sciences, ULisboa), is also coauthored by Cláudia Godinho (posdoc researcher) and the PhD student Nuno Bourbon-Melo (FCT_DP BIOTECnico) from the BSRG-iBB team.

Nutritional Composition, Bioactivity and Nanoencapsulation of Extracts from Wild Asparagus

Nutritional Composition, Bioactivity and Nanoencapsulation of Extracts from Wild Asparagus | iBB | Scoop.it

The nutritional composition and bioactive properties of roots and rhizomes of Asparagus stipularis were evaluated to demonstrate its potential in the food and pharmaceutical industries. HPLC-DAD-ESI/MS characterization of infusions allowed the identification and quantitation of 7 hydroxycinnamoyl derivatives, with caffeic acid as the most abundant. Roots infusion contained the highest amounts of these compounds. It also exhibited the highest antioxidant activity in all assays, with EC50 values of 0.44 ± 0.01, 0.98 ± 0.03 and 0.64 ± 0.01 mg/mL for DPPH, ABTS and FRAP assays, respectively, with no toxicity towards PLP2 primary cell cultures (GI50 > 400 μg/mL). The extract was encapsulated into PLGA nanoparticles obtaining a size of 260 nm and a polydispersity index around 0.1, with a zeta potential of -36 mV, as well as a good encapsulation efficiency of approximately 83%. The particles had a spherical morphology and smooth surface. FTIR and DSC assays confirmed the efficacy of the encapsulation methodology. This paper was published in Food Bioscience by Pedro Fonte from BERG-iBB in a transnational collaboration with researchers from Portugal, Spain, Italy and Tunisia. The developed systems will be used as delivery systems for bioactive compounds of A. stipularis and as an innovative dietary supplement.

Nanocarrier-Mediated Topical Insulin Delivery for Wound Healing

Nanocarrier-Mediated Topical Insulin Delivery for Wound Healing | iBB | Scoop.it

Wound care is clinically demanding due to treatment inefficiency and represents an economic burden for healthcare systems. A promising therapeutic strategy is the use of exogenous growth factors that are decreased at the wound site and hence limit recovery of the skin. Insulin is one of the cheapest growth factors in the market able to accelerate the re-epithelialization and stimulate angiogenesis and cell migration. However, the effectiveness of topical insulin in wound healing is hampered by the proteases in the wound bed. The encapsulation into nanoparticles improves its stability in the wound, providing adhesion to the mucosal surface and allowing its sustained release. In a paper published in Materials, Pedro Fonte from BERG-iBB in a collaboration with researchers from CCMAR, University of Algarve and LAQV, University of Porto performed a standing point about a promising strategy to treat different types of wounds by the topical delivery of insulin-loaded nanocarriers.

Xylonic Acid Production from Xylose by Paraburkholderia sacchari

Xylonic Acid Production from Xylose by Paraburkholderia sacchari | iBB | Scoop.it

Paraburkholderia sacchari has the capacity to produce xylonic acid and xylitol, compounds ranked in the top 30 high-value chemicals from biomass. In a recent paper in Biochemical Engineering Journal, Maryna Bondar, Manuela Fonseca and Teresa Cesário from BERG-iBB reveal the outstanding ability of this bacterium to metabolize D-xylose to xylonic acid. D-xylonic acid is a five-carbon sugar acid that can replace gluconic acid in several applications. The biotechnological production of D-xylonic acid is advantageous over gluconic acid because it uses xylose as carbon source. Xylose is a very abundant sugar in nature and only few native bacterial strains can metabolize it. Fed-batch cultivations in a single bioreactor attained xylonic acid titers of 390 g L-1 and a productivity of 7.7 g L-1 h-1. This simplified process can significantly affect process economics, potentiating its translation to an industrial scale.

Insights into the Cultured Bacterial Fraction of Corals | iBB | Scoop.it

Bacteria associated with coral hosts are diverse and abundant, with recent studies suggesting involvement of these symbionts in host resilience to anthropogenic stress. Combining published and unpublished data, a new article featuring iBB researchers Tina Keller-Costa and Rodrigo Costa among the authors provides a comprehensive overview of the diversity and function of culturable bacteria isolated from tropical, temperate, and cold-water corals. The study, published in the journal mSystems, compiles a total of 3,055 coral-associated isolates described in 52 reports from various laboratories around the world. The work presents a comparative genomic analysis of 74 strains and identifies signatures of potentially beneficial bacterium-coral symbioses among them. Such a resource is an important step in the selection of probiotic candidates, which are being investigated for promoting coral resilience and can potentially be applied in novel reef restoration and rehabilitation efforts. This genome and culture collection is available to the wider research community through the web site http://isolates.reefgenomics.org/ with the hope that many scientists across the globe will ask for access to these resources for future studies.
