An increased proportion of Indigenous American (IA) ancestry was associated with a greater incidence of HER2-positive breast cancer, according to a study published in Cancer Research, a journal of the American Association for Cancer Research.
A new study by researchers at the University of Hawai'i at Mānoa School of Ocean and Earth Science and Technology found that human-induced environmental stressors have a large effect on the genetic composition of coral reef populations in Hawai'i. They confirmed that there is an ongoing loss of sensitive genotypes in nearshore coral populations due to stressors resulting from poor land-use practices and coastal pollution. This reduced genetic diversity compromises reef resilience.
A new study in Neuron offers clues to why autism spectrum disorder (ASD) is more common in boys than in girls. National Institutes of Health scientists found that a single amino acid change in the NLGN4 gene, which has been linked to autism symptoms, may drive this difference in some cases. The study was conducted at NIH's National Institute of Neurological Disorders and Stroke (NINDS).
CECAD-researchers find a molecular repair pathway for cellular energy production, publication in 'Nature Communications'
Genetic variations in the skin can create a natural sunscreen, according to University of Queensland researchers investigating the genes linked with vitamin D.
Live, single-cell imaging shows cellular 'memory' of growth factor availability throughout the cell cycle (and not just snapshot of growth factor availability) influences cells' decision to replicate.
Researchers from King's College London have shown that how we respond to changes in nutrients at a molecular level plays an important role in the aging process, and this is directed by some key genetic mechanisms.
New research led by investigators from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences (CAS) describes how a key shoot stem cell-promoting gene activates its own expression, thus maintaining a stem cell lineage in the leaf axil that enables branching.
Nicotinamide can inhibit aggressive cell transformations during wound healing and may be key to the development of therapies to treat fibrotic eye diseases.
The rich biodiversity of coral reefs even extends to microbial communities within fish, according to new research. The study in Proceedings of the Royal Society: Biological Sciences reports that several important grazing fish on Caribbean coral reefs each harbor a distinct microbial community within their guts, revealing a new perspective on reef ecology.
