Outline of Research at the Start

Unlimited cancer cell proliferation is achieved by maintaining telomeres via either telomerase activation or ALT (alternative lengthening of telomeres). Constitutive ATM activation in response to telomere dysfunction in ALT-positive neuroblastoma (NB) cells contributes to chemoresistance. The detailed molecular mechanism behind the chemoresistance is still unclear. By this, we will elucidate the detailed molecular mechanism of chemotherapy resistance that is thought to exist in ALT-positive NB cells, and to identify new molecular targets for overcoming chemotherapeutic drug resistance.
