The ability of stem cells to self-renew has hung been attributed to an asymmetry in division that generates one daughter cell identical to the mother and another cell committed to differentiation. Recent studies on neuroblasts, a group of neural stem cells responsible for generating various neurons and glial cells in the central nervous system, have(More)
CPT-11 is an anticancer prodrug that is clinically used for the treatment of metastatic colorectal cancer. Hydrolysis of CPT-11 by human carboxylesterase 2 (CE2) generates SN-38, a topoisomerase I inhibitor that is the active anti-tumor agent. Expression of CE2 in cancer cells is under investigation for the tumor-localized activation of CPT-11. CE2 is(More)
