The short form of the serotonin transporter gene promoter does not explain autism, insists Dr. Cook, who heads a nationwide consortium of researchers looking for the genetic underpinnings of this disease, but it does appear to play a significant role, perhaps in concert with other abnormalities which we've not yet uncovered.

The second insight involved changes in the evolution of gene regulation: As social complexity increased, so did the speed of changes to parts of the genome involved in regulating gene activity, located in the promoters of the genes, the researchers report.
«You don't want to just turn down methylation globally, which would result in over-activation of all genes in the cell, but demethylating some of these gene promoter regions selectively could revive an immune system muted by cancer - causing viruses,» Kuss - Duerkop says.
Think of these promoter regions like on - off switches for next - door genes — when a promoter region is methylated, the switch is turned off and the gene it controls does not get read and expressed.

This last observation seems to indicate that promoter methylation does not play a significant role in regulation of gene expression between tissues.
The webinar will cover different virus types, understanding the screening process, dosing, dystrophin constructs, promoters, and how does the virus and gene that is delivered integrate into the muscle cell.
In cancers, aberrant promoter CpG island hypermethylation correlates highly with gene inactivation and can account for lack of gene expression where mutations do not exist.
