... accurate “bypass” polymerases can also cause mutations that contribute to carcinogenesis. In the cancer-prone human genetic disorder, xeroderma pigmentosum variant (XP-V), the function of DNA polymerase η, which can accurately bypass UV-induced TT dimers, is replaced by less accurate DNA polymerases ...

This leads to p70 S6 protein kinase (p70S6K) phosphorylation. This activation occurs synergistically with the activation by the c-MET-activated PI3 kinase. It ...

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.
