.. Children exposed to maternal smoking in utero possess increased DNA methylation in AXL gene Kids whose grandmothers or mothers smoked during pregnancy are in increased threat of asthma in childhood, but the underlying factors behind this aren’t well understood. Today a new study indicates changes in an activity called DNA methylation that occurs before birth could be a root cause. The scholarly study will be presented at the ATS 2011 International Meeting. DNA methylation is a process that can alter a gene’s usual function. These modified genes can be approved along from parent to child. In this case, researchers observed DNA methylation-related adjustments in the AXL gene in kids exposed to maternal cigarette smoking in utero.‘Second,’ he said, ‘we are almost addicted to television and computers.
