«Because many broadly expressed
genes that play key roles in essential 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.
