Selective requirement for Mediator MED23 in Ras-active lung cancer.

The article discusses a study that was conducted to examine the role of MED23 in lung cancer. The study used viral-mediated shRNA to inhibit Med23 expression in human lung cancer cell lines in combination with a Ras mutation. The findings of the study indicate that MED23 controls the proliferation of lung cancer cells in a Ras-dependent manner. It also revealed that Med23 deficiency in fibroblasts inhibited oncogenic transformation by Ras.
