Rationale: Nasopharyngeal carcinoma (NPC) is the most frequent head and neck tumor in South China. The presence of cancer stem cells (CSCs) in NPC contributes to tumor maintenance and therapeutic resistance, while the ability of CSCs to escape from the apoptosis pathway may render them the resistant property to the therapies. Inhibitor of apoptosis proteins family proteins (IAPs), which are overexpressed in nasopharyngeal carcinoma stem cells, may play an important role in maintaining nasopharyngeal cancer stem cell properties...

As the major and preferred treatment for ovarian cancer ascites, chemotherapy can reduce or inhibit recurrent ascites (hereafter re-ascites); however, some patients still experience re-ascites. Therefore, this study investigated cases in which epithelial ovarian cancer (EOC) patients experienced re-ascites. In re-ascites cases, CA125, MDR1, LC-3, and Beclin-1 were highly expressed. In addition, CASP-9 and c-CASP-3 expression levels were decreased, and serum CA125 levels (highest 4348 U/ml) were increased compared to chemosensitive cases...

Chemotherapy resistance is a major problem in the treatment of cancer, but the underlying mechanisms are not fully understood. We found that the expression levels of claudin-1 (CLDN1) and 3, tight junctional proteins, are upregulated in cisplatin (CDDP)-resistant human lung adenocarcinoma A549 (A549R) cells. A549R cells showed cross-resistance to doxorubicin (DXR). Here, the expression mechanism and function of CLDN1 and 3 were examined. CLDN1 and 3 were mainly localized at tight junctions concomitant with zonula occludens (ZO)-1, a scaffolding protein, in A549 and A549R cells...
