objective(s):multidrug resistance (mdr) of cancer cells is a major obstacle to successful chemotherapy. overexpression of breast cancer resistance protein (bcrp) is one of the major causes of mdr. in addition, it has been shown that pi3k/akt signaling pathway involves in drug resistance. therefore, we evaluated the effects of novel approaches including sirna directed against bcrp and targeted t...

background: osteosarcoma is a malignant tumor with high mortality but effective therapy has not yet been developed. berberine, an isoquinoline alkaloid component in several chinese herbs including huanglian, has been shown to induce growth inhibition and the apoptosis of certain cancer cells. the aim of this study was to determine the role of berberine on human osteosarcoma cell lines u2os and ...

The purpose of this study was to explore the mechanism Solanine disrupting energy metabolism in human renal cancer ACHN cells and clarify its target. specific method culture cell lines, intervene with high, medium low concentrations. content ATP measured by ELISA method. expression HIF-1α protein PI3K, AKT, p-PI3K, p-AKT PI3K/AKT pathway were detected Western blotting. results showed that compa...

Objective: To investigate the role of KIF3C gene in promoting malignant phenotype lung cancer cells and regulating PI3K/AKT signaling pathway. Methods: CCK-8 transwell assays were used to detect changes cell proliferation migration ability after being transfected with siKIF3C, as well protein expression levels PI3K, p-PI3K, AKT, p-AKT following downregulation by Western blot. Results: The assay...

Objective(s):Multidrug resistance (MDR) of cancer cells is a major obstacle to successful chemotherapy. Overexpression of breast cancer resistance protein (BCRP) is one of the major causes of MDR. In addition, it has been shown that PI3K/Akt signaling pathway involves in drug resistance. Therefore, we evaluated the effects of novel approaches including siRNA directed against BCRP and targeted t...

parkinson's disease (pd) is a chronic neurodegenerative condition which has the second largest incidence rate among all other neurodegenerative disorders barring alzheimer's disease (ad). currently there is no cure and researchers continue to probe the therapeutic prospect in cell cultures and animal models of pd. out of several factors contributing to pd prognosis, the role of p38 mapks (mitog...
