Ovarian cancer is one of the most common cancer among women in the world, and chemotherapy remains the principal treatment for patients. However, drug resistance is a major obstacle to the effective treatment of ovarian cancers and the underlying mechanism is not clear. An increased understanding of the mechanisms that underline the pathogenesis of drug resistance is therefore needed to develop novel therapeutics and diagnostic. Herein, we report the comparative analysis of the doxorubicin sensitive OVCAR8 cells and its doxorubicin-resistant variant NCI/ADR-RES cells using integrated global proteomics and N-glycoproteomics...

Herein we prepared folate-targeting core crosslinked polymeric micelles (CCL/FA) containing multiple disulfide bonds located on the interface and core of the micelles to co-deliver doxorubicin (DOX) and P-glycoprotein (P-gp) inhibitor tariquidar (TQR) for reversing drug resistance. The stability and redox-responsive behaviors of CCL/FA micelles were evaluated from the changes of morphology, molecular weight and the hydrodynamic size. On the one hand, the micelles possessed good stability that led to the suppression of drug release from the CCL micelles in physiological environment...

Antimicrotubule agent vincristine (VCR) has long been known as an alternative treatment for frequent relapse nephrotic syndrome and steroid-dependent nephrotic syndrome (SDNS). However, the mechanism is unknown. Here we found that VCR at a dosage much lower than that as an antimicrotubule agent can alleviate adriamycin (ADR)-induced proteinuria and podocyte foot process effacement. In cultured podocytes, VCR prevents ADR-induced actin fiber disorganization. In both in vitro and in vivo models, VCR suppresses ADR-induced overexpression of α3β1 integrin and focal adhesion kinase (FAK)...

Bone morphogenetic protein-9 (BMP9) shows great osteoinductive potential in bone regeneration. Periodontal ligament stem cells (PDLSCs) with multi-differentiation capability and low immunogenicity are increasingly used as seed cells for periodontal regenerative therapies. In the present study, we investigated the potent osteogenic activity of BMP9 on human PDLSCs (hPDLSCs), in which the c-Jun N-terminal kinase (JNK) pathway is possibly involved. Our results showed that JNK inhibition by the specific inhibitor SP600125 or adenovirus expressing small interfering RNA (siRNA) targeting JNK (AdR-si-JNK) significantly decreased BMP9-induced gene and protein expression of early and late osteogenic markers, such as runt-related transcription factor 2 (Runx2), alkaline phosphatase (ALP), osteopontin (OPN), and osteocalcin (OCN), in hPDLSCs...
