A study found that naltrexone increased the urge to drink in individuals with a positive family history, suggesting genetic factors at play. The OPRM1 gene was identified as a key genetic moderator of naltrexone's effects on alcohol cue reactivity.
Scientists have discovered that an enzyme called RNA-dependent RNA polymerase is needed for paramutation, a phenomenon where one version of a gene can order another to act differently. This finding has significant implications for breeding better crop plants and unraveling complex genetic diseases, including some human health conditions.
A comprehensive literature-derived database of yeast interactions has been created, containing over 22,000 protein interactions and 11,000 genetic interactions. The database is publicly available and enables researchers to gain further insight into individual gene functions and biological network features in yeast.
Researchers identified a genetic network in yeast that guards against lethal DNA damage, which could lead to new therapies for human diseases such as cancer and aging. The study used a technology called dSLAM to map the interactions between genes involved in DNA repair, replication, and cell cycle progression.
Recent genetic epidemiology studies have empirically supported Mayr's ideas on genetic interaction and its impact on evolutionary change. These studies show that genes interact extensively, leading to a strong interaction between natural selection and genetic drift, resulting in 'genetic revolution.'
E-MAP technique enables researchers to analyze epistatic interactions between genes in a systematic way, revealing new insights into protein functions and evolutionary processes. By quantifying the effects of interacting mutant genes, E-MAPs help optimize drug treatments and improve our understanding of biological systems.
Researchers discovered a genetic basis for idiopathic pulmonary fibrosis, with those having ever smoked cigarettes being 3.6 times more likely to develop the disease. The study also highlights the importance of avoiding cigarette smoking as a preventive measure for this devastating lung condition.
A study by University of Florida researchers found that certain gene variants interact with physical activity to affect mobility in seniors. Those with specific genes, such as the DD genotype, were more likely to remain mobile and experienced less decline, even among those who exercised regularly.
The study found that complex gene-gene interactions are likely responsible for the development of autism. The GABA brain system is implicated in this process, with multiple genes working together to influence the disease.
