... Thus the rates at which cancer cells become drug resistant or lose resistance are 4–11 orders higher than conventional mutation rates. These exceptionally high rates have thus been called “intrinsic mutability” to signal as yet unknown cancerspecific mechanisms (Chabner and Roberts, 2005). The rapid ...

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.
