Wed, Jan 19, 2011 — In a study published in the Cell Press journal Developmental Cell, a team of researchers led by Channing Der, PhD, Distinguished Professor of Pharmacology at UNC-Chapel Hill, took a step back to a simpler organism – a common roundworm – and made a discovery about how the Ras oncogene chooses a signaling pathway and how the consequences of that choice play out in cellular development – a key issue in cancer, which is characterized by uncontrolled cell growth.

Massachusetts General Hospital (MGH) Cancer Center researchers have discovered a previously unknown feature of common tumor cells – massive overexpression of certain DNA sequences that do not code for proteins.  These DNA sequences – called satellite repeats – have been studied for their role in chromosomal structure but previously were not suspected of having a role in cancer.  The report will appear in the journal Science and is receiving early online release.
