| Research Abstract |
We aimed to identify molecules involved in cell death after prolonged mitotic arrest by anti-cancer drugs. When cells depleted of CAMP, a novel molecule we identified, were treated with microtubule inhibitors, we found the acceleration of cell death after mitotic arrest specifically in cancer cell lines. There was a tendency that cancer cell lines showed higher expression of CAMP than normal cell lines, implying that cancer cell survival is dependent on CAMP. Expression of Mcl-1 and Bcl-xL, anti-apoptotic Bcl-2 family members, was decreased in CAMP-depleted cells, suggesting that CAMP can be a target for anti-cancer therapy.
