A novel approach for enriching cancer stem cells from the human SW-13 adrenocortical carcinoma cell line.

The present study was undertaken to develop a new method for enriching cancer stem cells (CSCs) from the human adrenal cortical carcinoma (ACC) cell line SW-13. Given that the existence of CSCs in ACC causes resistance to conventional chemotherapies, treatment with cyclophosphamide was used for in vivo selection of CSCs in a BALB/c nude mouse tumor xenograft model established using the ACC cell line SW-13. The characteristics of CSCs in three generations of tumor xenografts were assessed for single-cell colony formation, flat colony formation, and cell sphere formation in serum-free suspension culture.

Enhancement of cisplatin-induced apoptosis by β-elemene in resistant human ovarian cancer cells.

β-Elemene is a new anticancer compound extracted from the Chinese medicinal herb Rhizoma zedoariae. We have shown previously that β-elemene increases cisplatin cytotoxicity and enhances cisplatin sensitivity via blocking cell cycle progression at G2/M phase in resistant ovarian tumor cells. In the current study, we asked whether β-elemene-augmented cisplatin activity in ovarian carcinoma cells is mediated through the induction of apoptosis.
