Dataset Summary
TitleProtein Kinase C activation regulates NDRG1 expression
DescriptionN-myc downstream regulated gene 1 (NDRG1) is a member of the NDRG family of intracellular proteins, and plays a central role in a wide range of biological processes including stress response, differentiation, and maintenance of the myelin sheath. The overexpression of NDRG1 is an indicator of poor prognosis in various pathological conditions. Here, we found that NDRG1 is an independent prognostic marker of poor outcome in breast cancer (BC). NDRG1 expression is regulated by a variety of molecular mechanisms, including transcriptional and post-translational control. In the present study, CRISPR-based inactivation of NDRG1 allowed us to demonstrate that this protein is required for breast cancer cell invasion, without affecting viability. We observed that different acute stress conditions converge on protein kinase C (PKC) activation driving enhanced NDRG1 expression through a signaling pathway that involves ROCK/AMPK/Akt kinases. This newly discovered mechanism was specific for NDRG1 as the expression of other NDRG members was not affected. Together, our results suggest that pathophysiological PKC-mediated activation of NDRG1 may be a response mechanism to metabolic stress and anticancer agents.
