Epigenetic changes regulate gene expression, but what regulates epigenetics?
Scientists at the Salk Institute have discovered a new mode of epigenetic targeting in plant cells, where specific DNA sequences guide DNA methylation patterns. This finding has major implications for understanding epigenetic regulation and could inform future strategies for epigenetic engineering.
You are what you eat…and so are your grandkids? Study links poor diet to multi-generational health issues
A study from Tulane University found that a low-protein diet in one generation can lead to lower birthweights and smaller kidneys in offspring across multiple generations. The findings suggest that food scarcity or malnutrition may result in decades of adverse health outcomes.
New resource maps gene-disease links across common conditions, paving the way for personalized medicine
A new study introduces the PWAS Hub, a powerful tool that explores gene-disease connections across 99 common diseases. The platform identifies genes linked to specific conditions and provides valuable genetic insights for clinicians and researchers.
Tradition meets transformation for Maasai women
A new study reveals that Maasai women are gaining access to household decisions through livelihood diversification, education, and secure land tenure. This research contributes to the United Nation's Sustainable Development Goal of Gender Equality, highlighting the value of empowering decision-making for women in pastoralist communities.
Research reveals novel CARS E795V mutation as cause of inherited Parkinson's disease
Researchers discovered a new genetic cause of inherited Parkinson's disease, the CARS E795V mutation, which affects protein function and leads to neurological symptoms. The study found that this rare mutation is responsible for the condition in nine individuals from four families.
New genetic clues uncovered in largest study of families with multiple children with autism
Researchers found seven potential genes linked to increased autism risk, including rare inherited variations and polygenic scores. Children with language delays had a higher likelihood of inheriting these genes, suggesting a link between genetic risk and language delay.
Schizophrenia is associated with somatic mutations occurring in utero
Researchers found a correlation between somatic copy-number variants and schizophrenia, with genes NRXN1 and ABCB11 being identified as key players. These mutations occur early in development but after genetic material is inherited, and are present only in a fraction of cells.
New method traces ancestry of hybrid plants and animals
A biologist at Binghamton University has developed a new method to uncover the parent species of hybrid plants and animals. By examining genomic patterns within these hybrids, researchers can identify distinct ancestries and determine the order in which chromosomes were inherited from their progenitor species.
Scientists move a step closer to understanding why leopards can't change their spots
Researchers have identified at least three different genes involved in the emergence of stripes, spots, and other markings on domestic cats. The study's findings may also contribute to understanding human skin disorders that follow standardized patterns.
Blue eyes -- A clue to paternity
Researchers found that blue-eyed men rate blue-eyed female models as more attractive than brown-eyed models. In a second study, blue-eyed men were more likely to have romantic partners of the same eye color.
Genetics used to prove linguistic theories
A genetic analysis by Francisco Salzano and colleagues supports Rodrigues' suggestion of a close connection between Carib and Tupi, while Je and Maipure show more distant relationships. The study provides new insights into the complex history of South American Native languages.
Gene mutation results in missing teeth
Scientists discovered a PAX9 gene mutation causing congenitally absent molars in a Houston family, revealing insights into the genetics of human tooth development. The study, published in Nature Genetics, used molecular epidemiology and DNA analysis to identify the responsible gene, which is activated early in tooth development.
Researchers Discover The Pattern Of Inheritance Of Non-Chromosomal DNA
Researchers at UT Southwestern Medical Center have shown that the transmission of mtDNA in yeast is organized and finite, rather than random. This discovery has implications for understanding genetic disorders caused by mtDNA mutations in humans, where the mother passes on a minority of her mtDNA copies to the fetus.
Menstrual Irregularities May Indicate Genetic Disorder
Women with polycystic ovary syndrome (PCOS) may experience menstrual irregularities, infertility, and increased body hair due to hormonal imbalances. Research suggests that PCOS may be inherited, affecting both males and females in the family.
