Scientists uncover how newly discovered gene helps grow blood vessels

A new study published today found that a newly discovered gene helps grow blood vessels when it senses inadequate blood flow to tissues.

Scientists identify four viruses that can produce insulin-like hormones

Every cell in your body responds to the hormone insulin, and if that process starts to fail, you get diabetes. In an unexpected finding, scientists at Joslin Diabetes Center have identified four viruses that can produce insulin-like hormones that are active on human cells.

Stanford researchers explore how enzyme changes and becomes antibiotic-resistant

Enzymes are proteins that speed up or catalyze a reaction in living organisms. Bacteria can produce enzymes that make them resistant to antibiotics.

Key protein involved in epigenetic regulation of gene expression guides skin cell renewal

Approximately once a month, our skin completely renews itself. If this highly coordinated process goes awry, it can lead to a variety of skin diseases, ranging from skin cancer to psoriasis.

Father's stress affects the brain development of offspring, mice study shows

New research in mice has found that a father's stress affects the brain development of his offspring. This stress changes the father's sperm, which can then alter the brain development of the child. This new research provides a much better understanding of the key role that fathers play in the brain development of offspring.

Scientists develop water-soluble warped nanographene for bioimaging

An international team of scientists has developed a water-soluble "warped nanographene", a flexible molecule that is biocompatible and shows promise for fluorescent cell imaging.

Liquid biopsies could be used as new predictive marker for metastatic TNBC

A clinically relevant "liquid biopsy" test can be used to profile cancer genomes from blood and predict survival outcomes for patients with metastatic triple negative breast cancer, according to new research published by a multi-institutional team of researchers with The Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, the Dana-Farber Cancer Institute and the Broad Institute of MIT and Harvard.

Researchers uncover how excess calcium may influence development of Parkinson’s disease

Researchers have found that excess levels of calcium in brain cells may lead to the formation of toxic clusters that are the hallmark of Parkinson's disease.

Early childhood immune signature predicts risk of developing asthma later on

Asthma is a chronic inflammatory disease driven by the interplay of genetics, environmental factors and a diverse cast of immune cells.

Researchers uncover Ras protein's role in uncontrolled cancer growth

Protein systems, such as Ras, make up the complex signaling pathways that control whether a cell divides or, in some cases, becomes cancerous and metastasizes into other regions of the body. For example, 98 percent of pancreatic cancers show Ras protein mutations.

Scientists develop fluorescent probe to identify cancer stem cells

Cells with stem-cell characteristics appear to be especially important in the formation and metastasis of tumors. Scientists have now developed a universal fluorescent probe for these “cancer stem cells”. As reported in the journal Angewandte Chemie, this dye also selectively kills off the cells.

Russian researchers develop new multi-layered biodegradable scaffolds

A team of young researchers at the National University of Science and Technology has recently presented its new development – therapeutic material based on nanofibers of polycaprolactone, modified with plasma-deposited thin layers enriched with antibacterial composition and human blood plasma components.

Women exposed to cleaning products suffer decreased lung function, finds study

A new study has found that females who use cleaning products at home or are employed as cleaners are more prone to the risks of deteriorated lung function than women who do not clean.

Stem cell vaccine helps protect mice against numerous cancers, finds study

Lab mice injected with inactivated induced pluripotent stem cells (iPSCs) displayed a significant immune response against lung, breast, and skin cancers. The vaccine also prevented relapses in animals with removed tumors.

Major review suggests link between female sex hormones and allergies, asthma

Fluctuations in female sex hormones could play a role in the development of allergies and asthma, a major review of evidence suggests.

Genetic risk score could help predict patient's quality of life after traumatic brain injury

A new study presented this week at the Association of Academic Physiatrists Annual Meeting in Atlanta found that a genetic risk score could help predict a patient's quality of life after a traumatic brain injury. One day, physicians could have a simple, early method to forecast a patient's recovery and personalize therapy to maximize their quality of life down the road.
