| Research Abstract |
We showed for the first time that gamma secretase (GS) complexes regulate the response of colon and pancreatic cancer cells to taxanes through GS-dependent and GS-independent mechanisms. GS-dependent pathway is independent of Notch signaling. Interestingly, it was strongly indicated that GS complexes regulate the cell cycle progression of these cells in a GS-independent manner. Data suggest that GS complexes could be a new therapeutic target for overcoming resistance to taxanes in these cancers.
