Lake Nona, Fla., August 25, 2016 -- Scientists at the Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a previously unknown way that stress hormones (glucocorticoids) shut off genes in the liver to help the body adapt to the fasting state. The study, published today in Cell Metabolism, describes an obscure protein, SETDB2, that's increased during times of fasting and alters the genome to help turn on genes needed to adjust to the absence of food.

Researchers at the University of Adelaide have successfully trialed a new technique that could aid the process of choosing the "best" embryo for implantation, helping to boost the chances of pregnancy success from the very first IVF cycle.

A group of proteins best known for helping to activate all mammalian genes has been found to play a particularly commanding role in the natural development of specialized stem cells into healthy blood cells, a process known as hematopoiesis.

Researchers have identified a mechanism in mice by which anticancer immune responses are inhibited within the lungs, a common site of metastasis for many cancers. This mechanism involves oxygen inhibition of the anticancer activity of T cells. Inhibiting the oxygen-sensing capability of immune cells, either genetically or pharmacologically, prevented lung metastasis.

A new study published online by JAMA Oncology quantifies industry financial conflicts of interest (FCOIs) among authors of National Comprehensive Cancer Network (NCCN) guidelines, work that influences practice and defines drugs reimbursable by Medicare.

Aaron P. Mitchell, M.D., of the University of North Carolina at Chapel Hill School of Medicine, and coauthors examined FCOIs during 2014 among 125 authors of the guidelines for the treatment of breast, colon, prostate and lung cancer because those are the cancers with the highest incidence in the U.S.

Does how much hair a man has matter in how he is perceived? The answer is yes, according to a new article published online by JAMA Facial Plastic Surgery.

A survey by Lisa E. Ishii, M.D., M.H.S., of Johns Hopkins University School of Medicine, Baltimore, and coauthors suggests men with androgenetic alopecia (pattern baldness) who underwent hair transplant were rated by observers as more youthful, attractive, successful and approachable. All those factors can play a role in workplace and social success.

New Haven, Conn.-- The Zika virus reproduces in the vaginal tissue of pregnant mice several days after infection, according to a study by Yale researchers. From the genitals, the virus spreads and infects the fetal brain, impairing fetal development. The findings suggest that the Zika virus may replicate more robustly in the female reproductive tract than at other sites of infection, with potentially dire consequences for reproduction, said the researchers.

The study was published online Aug. 25 in Cell.

COLUMBUS, Ohio - The same mechanisms that that prevent people from having an inflammatory response to harmless environmental exposures in day-to-day life could also all allow rogue cancer cells to spread to the lungs, according to new research from The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James).

CHAPEL HILL - Nearly nine out of 10 physicians and researchers who helped develop a leading set of cancer care guidelines in the United States reported financial ties to the pharmaceutical and medical device industries, a University of North Carolina Lineberger Comprehensive Cancer Center study found.

SCIENTISTS have demonstrated for the first time the 'perfect storm' of conditions that cells need to start forming cancer, helping to explain why some organs are more susceptible to developing the disease, according to a new study published in Cell today (Thursday).

DURHAM, N.C. - The forward march of science often blunders into the realization that nature's way of doing things is a lot more complicated than we thought.

So it is apparently with the process that activates genes to start the machinery for manufacturing proteins, according to a team of Duke scientists.

LA JOLLA--Salk Institute scientists have discovered the holy grail of endless youthfulness--at least when it comes to one type of human kidney precursor cell. Previous attempts to maintain cultures of the so-called nephron progenitor cells often failed, as the cells died or gradually lost their developmental potential rather than staying in a more medically useful precursor state.

PASADENA, Calif., Aug. 25, 2016 -- A new Kaiser Permanente study found an increased risk for becoming overweight or obese among normal-weight 18-year-olds who lived in neighborhoods with lower education or income levels. The study, published today in Pediatric Obesity, found that over a four-year period, 25 percent of these young adults became overweight or obese.

Internal conflict between cell types explains why the immune system struggles to recognize and attack pancreatic cancer. Curbing this infighting has the potential to make treatment more effective, according to a study led by researchers from NYU Langone Medical Center and its Perlmutter Cancer Center.

Proteins perform a wide range of tasks within cells. For everything to run smoothly, the cell must make sure that all the necessary proteins are available and that they are in good condition. Faulty proteins are labeled as such and then recycled. Ligase complexes are able to identify aberrant proteins and attach a small regulatory protein called ubiquitin (Ub) to mark them as faulty. However, further steps are needed before the protein degradation pathway is triggered.
