Study finds link between genes affected by testosterone and antibody responses to influenza vaccine

A new study has identified a link between certain genes affected by testosterone and antibody responses to an influenza vaccine. The findings, published in Proceedings of the National Academy of Sciences, suggest that testosterone levels may partially explain why men often have weaker responses to vaccines than women.

Changes to LZTR1 gene predispose people to develop schwannomas

Changes to a gene called LZTR1 predispose people to develop a rare disorder where multiple tumors called schwannomas form near nerve pathways, according to a study published today in the journal Nature Genetics and led by researchers from the University of Alabama at Birmingham.

Researchers report new gene delivery method that targets tumor blood vessels

Working in mice, researchers at Washington University School of Medicine in St. Louis report developing a gene delivery method long sought in the field of gene therapy: a deactivated virus carrying a gene of interest that can be injected into the bloodstream and make its way to the right cells.

Epithelial-to-mesenchymal transition beneficial to cardiac regeneration

Cell-based therapies have been shown to enhance cardiac regeneration, but autologous (patient self-donated) cells have produced only "modest results." In an effort to improve myocardial regeneration through cell transplantation, a research team from Germany has taken epithelial cells from placenta (amniotic epithelial cells, or AECs) and converted them into mesenchymal cells. After transplanting the transitioned cells into mice modelling a myocardial infarction, the researchers found that the epithelial-to-mesenchymal transition was beneficial to cardiac regeneration by lowering infarct size.

Research findings reveal how immune system responds to respiratory viral infections

An antibody that blocks a component of a key signaling pathway in the respiratory airways could help the immune system rid the body of the influenza virus, a new study suggests. The findings, from a team at The Research Institute at Nationwide Children's Hospital, not only offer a new approach to treating the flu, but also add new information about how the immune system responds to respiratory viral infections.

Variation in oxytocin receptor gene influences face recognition skills, study finds

New findings suggest the oxytocin receptor, a gene known to influence mother-infant bonding and pair bonding in monogamous species, also plays a special role in the ability to remember faces. This research has important implications for disorders in which social information processing is disrupted, including autism spectrum disorder. In addition, the finding may lead to new strategies for improving social cognition in several psychiatric disorders.

Researchers examine link between pregnant mothers eating peanuts, tree nuts and risk of allergies in kids

Children appear to be less at risk for developing peanut or tree nut (P/TN) allergies if their mothers are not allergic and ate more nuts during pregnancy, according to a study published by JAMA Pediatrics, a JAMA Network publication.

Humans with high motor excitability have better working memory

Humans with a high motor excitability have a better working memory than humans with a low excitability. This was shown in a study conducted by scientists from the Transfacultary Research Platform at the University of Basel. By measuring the motor excitability, conclusions can be drawn as to the general cortical excitability - as well as to cognitive performance.

Genetic screening identifies genes driving resistance with guide RNA library

Researchers have developed a method to create a comprehensive library of mutations across all genes in the mouse genome. This library can be used to examine the role of every gene in different cell types.

Finding suggests new route for packaging RNA molecules of interest into nanovesicles

The role of microRNAs is fundamental for the correct moment-to-moment adjustment in the expression of target genes. "Before this study, we already knew that these small molecules could be packaged into small vesicles and exported to the extracellular space, to be later captured by other cells and in this way play an important role in intercellular communication," explains CNIC researcher Carolina Villarroya, the first author on the study.

Melanocyte-secreted fibromodulin promotes angiogenic microenvironment

The decreased vision loss that accompanies age-related macular degeneration (AMD) is associated with abnormal blood vessel growth in the eye. Frequencies of AMD development are different among racial backgrounds, with occurrence of AMD highest among individuals of mixed European decent.

PAZ extracts may be useful option for improving plasma cholesterol profile

Health Enhancement Products, Inc., in conjunction with Wayne State University's Department of Nutrition and Food Science in the College of Liberal Arts and Sciences, announces the publication of a scientific article in the Journal of Nutrition & Metabolism, "ProAlgaZyme sub-fraction improves the lipoprotein profile of hypercholesterolemic hamsters, while inhibiting production of betaine, carnitine, and choline metabolites."

Small molecule nonsense suppression strategy for aniridia-associated defects

Congenital aniridia is a progressive disease that is associated with improper development of eye structures as well as abnormalities in the brain and pancreas. A variety of nonsense mutations in the PAX6 gene are linked with aniridia; however, despite understanding the genetic basis of the disease, few treatment and prevention strategies are available.

Scientists develop new potential cure for rare eye disease

University of British Columbia and Vancouver Coastal Health scientists have developed a potential cure for a rare eye disease, showing for the first time that a drug can repair a birth defect.

Research finding could lead to development of vaccine and therapies for mucormycosis

Mucormycosis is a deadly infection that strikes people with weakened immune systems when certain types of fungi, called Mucorales, invade the patients' cells. A novel protein on the surface of the Mucorales cells, called CotH, makes this invasion possible.

Studies yield new insights into molecular mechanisms that underlie learning process

Learning requires constant reconfiguration of the connections between nerve cells. Two new studies now yield new insights into the molecular mechanisms that underlie the learning process.

Manipulating epigenetic mechanism may promote cell death in pediatric brain cancer

Researchers at the Federal University of Rio Grande do Sul, the university hospital (Hospital de Cl-nicas de Porto Alegre, HCPA) and the Children's Cancer Institute (Instituto do C-ncer Infantil do Rio Grande do Sul, ICI-RS) in Porto Alegre, Brazil, have shown that manipulating an epigenetic mechanism, which regulates gene expression, may promote cell death and favor maturation towards less malignant-prone phenotypes in pediatric brain cancer cell lines.

Engineered immune cells show antitumor activity in two patients with advanced cancers

Engineered immune cells, called CARTmeso cells, designed to direct antitumor immune responses toward tumors that carry a protein called mesothelin, showed antitumor activity in two patients with advanced cancers that had not responded to prior treatments, according to a study published in Cancer Immunology Research, a journal of the American Association for Cancer Research.

Six common diseases arise from DNA changes, finds new research

Many rare disorders are caused by gene mutation, like sickle cell anemia. Yet until now the underlying genetic cause of more common conditions - for example, rheumatoid arthritis - has evaded scientists for years.
