Large Sex Differences in Chicken Behavior and Differences in Promoter DNA-Methylation

... birds partially use mammalian-type dosage compensation to circumvent some of the problems [12] [13]. In this context, a so called male hypermethylated region (MHM) on the Z-chromosome has been identified [14], and just like Xist it transcribes a large noncoding RNA that is thought to mediate DNA-met ...

Polycomb Group Proteins and Cancer

The Polycomb-group proteins (PcGs) are a family of proteins that use epigenetic mechanisms to maintain or repress expression of their target genes. They were originally discovered in Drosophila (fruit flies), though they've been shown to be conserved in many species due to their vital roles in embryonic development. These proteins' ability to alter gene expression has made them targets of investigation for research groups seeking to understand disease pathology and oncology.
