Possible ‘Central Hub’ Proteins Found in Cancer Cell Growth

A study from researchers at The Children’s Hospital of Philadelphia may add new lines to the textbook description of how cancer cells divide uncontrollably and develop into tumors. Their study, published in Nature Communications, identifies and describes an epigenetic mechanism in cancer cells that amplifies the expression of many genes and could be a central hub in cancer cell growth. Unlike most molecular cancer discoveries that advance knowledge of the disease by dividing it into narrower subtypes, this finding could directly apply to multiple cancer types.

“We know the signaling pathway known as the Rb pathway is altered in pretty much every single tumor that you can find in clinical settings,” said Patrick Viatour, PharmD, PhD, the study’s senior author, an investigator at CHOP, assistant professor of Pathology and Laboratory Medicine at the Perelman School of Medicine at the University of Pennsylvania, and member of the Institute for Regenerative Medicine.
