The emerging field of epigenetics has added a new dimension to the “nature versus nurture” debate, by which researchers have historically attempted to determine whether a characteristic was influenced by genes or environment. Increasingly, it appears that environmental influences can affect gene expression, meaning that “nature” and “nurture” are inextricable from one another to an even greater extent than previously understood.
Researchers at the National Institutes of Health and other institutions have discovered the third in a sequence of genes that accounts for previously unexplained forms of osteogenesis imperfecta (OI), a genetic condition that weakens bones, results in frequent fractures and is sometimes fatal.
At the annual meeting of the American Association for Cancer Research (AACR) last month, researchers from GeneNews Corp. reported that the probability of colorectal cancer (CRC) in asymptomatic patients can be accurately stratified by RNA expression profiling of six genes in whole blood . The company focuses on developing blood-based biomarker tests for the early detection of diseases and personalized health management.
