Some autopsy data shows that infants of smokers have signs of established hypoxic - ischemic
cellular injury in the brain and the heart which probably occurred in antenatal life, may have been caused by suboptimal placental
function and may have been sub-clinical, but if the baby continues to be in a vulnerable environment exposed to post-natal passive smoking, this could affect autonomic nervous system
function and lead to poor temperature
control, and poor heart rate and respiration
control.

cellular functions are under the
control of cell - specific enhancers, the ability to affect enhancer
function by knocking down eRNAs could potentially provide a new strategy for altering gene expression in vivo in a cell - specific manner,» said Glass, noting that in his research, anti-sense oligonucleotides were developed in conjunction with Isis Pharmaceuticals, which suppressed enhancer activity and reduced expression in nearby genes.
