NVP-BEZ235 synergizes cisplatin sensitivity in osteosarcoma
Osteosarcoma(OS) remains a major health concern in childhood and adolescence, although cisplatin is one of the gold standard chemotherapeutic drugs in the treatment of OS, chemoresistant to cisplatin is common. Phosphoinositide 3-kinase (PI3K)-Akt-mammalian target of rapamycin inhibitor (mTOR) pathway and autophagy regulates chemosensitivity incancer cells. In this study, we hypothesized that N...
متن کاملKnockdown of Akt Sensitizes Osteosarcoma Cells to Apoptosis Induced by Cisplatin Treatment
Akt plays an important role in the inhibition of apoptosis induced by chemotherapy and other stimuli. We therefore investigated if knockdown of Akt2 promoted drug-induced apoptosis in cultured osteosarcoma cells in vitro. SAOS-2 cells were transfected with Akt2 siRNA. The sensitivity of the transformed cell line to the chemotherapeutic drug cisplatin was assessed. Reduced expression of Akt2 did...
متن کاملc-Jun knockdown sensitizes osteosarcoma to doxorubicin.
The oncogene c-Jun has been found to be up-regulated in a variety of cancers, including osteosarcoma. Doxorubicin is a frontline chemotherapeutic against osteosarcoma, but is limited by toxicity. DNAzymes are oligonucleotides capable of specific catalysis of target mRNA. A biocompatible c-Jun DNAzyme nanoparticle formulated from chitosan regressed the growth and metastasis of pre-established tu...
متن کاملMicroRNA‑224 promotes the sensitivity of osteosarcoma cells to cisplatin by targeting Rac1
Osteosarcoma is the most common primary bone tumour in children and adolescents. Accumulating evidence has shown that microRNAs (miRNAs) participate in the development of almost all types of cancer. Here, we investigated the role of miR-224 in the development and progression of osteosarcoma. We demonstrated that miR-224 was down-regulated in osteosarcoma cell lines and tissues. Lower miR-224 le...
متن کاملGene expression profiles classify human osteosarcoma xenografts according to sensitivity to doxorubicin, cisplatin, and ifosfamide.
PURPOSE In osteosarcoma, aggressive preoperative and postoperative multidrug chemotherapy given to all patients has improved patient survival rate to the present level of approximately 60%. However, no tumor marker is available that reliably can identify those patients who will or will not respond to chemotherapy. EXPERIMENTAL DESIGN In an attempt to find leads to such markers, we have obtain...
