Integrin-linked kinase (ILK) facilitates signal transduction between extracellular events and important intracellular survival pathways involving protein kinase B/Akt. We examined the role of ILK in determining pancreatic adenocarcinoma cellular chemoresistance to the nucleoside analogue gemcitabine. Cellular ILK expression was quantified by Western blot analysis. We examined the effects of ove...
Nano Cell Cycle Checkpoint Inhibitors In article number 2300736, Daishun Ling, Fangyuan Li, and co-workers demonstrate that ultra-small iron oxide nanoparticles (IONPs) can serve as a selective nano cell cycle checkpoint inhibitor (NCCI) to catalyze the intracellular H2O2 into abundant ·OH, cleave heat shock protein 90 (Hsp90), thus induce degradation of client ATR/CHK1, leading dysfunction G2/...
Temozolomide (TMZ) is an oral alkylating agent used for the treatment of high-grade gliomas. Acquired chemoresistance is a severe limitation to this therapy with more than 90% of recurrent gliomas showing no response to a second cycle of chemotherapy. Efforts to better understand the underlying mechanisms of acquired chemoresistance to TMZ and potential strategies to overcome chemoresistance ar...
Chemoresistance is one of the major obstacles in systemic chemotherapy and targeted therapy for patients with advanced hepatocellular carcinoma. To identify novel chemoresistance-associated targets in hepatocellular carcinoma, chemoresistant hepatocellular carcinoma cell lines were established. By comparing the global gene expression profiles between chemoresistant and chemosensitive cell lines...
Tumor-associated macrophages play a central role in tumor progression and metastasis. Macrophages can also promote the resistance of malignant cells to chemotherapy by stimulating the upregulation of cytidine deaminase, an intracellular enzyme that catabolizes the active form of gemcitabine. Targeting macrophage-dependent chemoresistance may reduce tumor-associated morbidity and mortality.
The high mortality of epithelial ovarian cancer (EOC) is mainly caused by resistance to the available therapies. In EOC, the endothelin-1 (ET-1, EDN1)-endothelin A receptor (ETAR, EDNRA) signaling axis regulates the epithelial-mesenchymal transition (EMT) and a chemoresistant phenotype. However, there is a paucity of knowledge about how ET-1 mediates drug resistance. Here, we define a novel byp...
CONTEXT Prediction of high probability of survival from standard cancer treatments is fundamental for individualized cancer treatment strategies. OBJECTIVE To develop a predictor of response and survival from chemotherapy for newly diagnosed invasive breast cancer. DESIGN, SETTING, AND PATIENTS Prospective multicenter study conducted from June 2000 to March 2010 at the M. D. Anderson Cancer...
Ovarian cancer is one of the most deadly malignancies in women because of its poor prognosis and that a majority of patients are diagnosed at advanced stage. Therefore, chemotherapy becomes the most important treatment option in most ovarian cancer cases. However, chemoresistance in relapsed cases is the major obstacle for the clinical management of this disease. Mounting evidences have suggest...
Knowledge of the mechanisms underlying chemoresistance is important in the development of novel targeted treatments for ovarian cancer. We recently reported that targeting endothelin A receptor/β-arrestin-1, a binding partner of Wnt/β-catenin, is sufficient to sensitize ovarian cancer to chemotherapy. This result highlights endothelin-1 receptor antagonists as potential anticancer therapeutics.
OBJECTIVE Triple-negative breast cancer (TNBC) patients with truly chemosensitive disease still represent a minority among all TNBC patients. The aim of the present study is to identify microRNAs (miRNAs) that correlate with TNBC chemoresistance. METHODS In this study, we conducted miRNAs profile comparison between triple-negative breast cancer (TNBCs) and normal breast tissues by microRNA ar...
