Increased expression of heat shock protein-binding protein 1 and heat shock protein 70 in human hepatocellular carcinoma tissues.
Heat shock protein-binding protein 1 (HspBP1) is a co-chaperone that inhibits heat shock 70-kDa protein (Hsp70) activity. In mouse neuroblastomas and lung tumors, the protein levels of HspBP1 and Hsp70 are elevated by a similar amount compared to non-tumor tissues. However, no studies have been reported regarding the levels of HspBP1 in human cancer tissues. Our previous proteomic study demonst...
متن کاملEffects of hepatitis C virus NS3 protein on expression of heat shock protein 70 and Glypican3 as the markers of hepatocellular carcinoma
Background and Aims: Hepatitis C virus (HCV) infection is an important risk factor for the development of liver cancer. The HCV NS3 protein plays a key role in the virus life cycle and can affect normal cellular activities, such as cell proliferation, cell death, and cell signaling pathways. Moreover, it may influence malignancy development. Two cellular genes, heat shock protein 70 (HSP70) and...
متن کاملN,N'-Dinitrosopiperazine–Mediated Heat-Shock Protein 70-2 Expression Is Involved in Metastasis of Nasopharyngeal Carcinoma
N,N'-Dinitrosopiperazine (DNP) is invovled in nasopharyngeal carcinoma (NPC) development and metastasis, and it shows organ specificity to the nasopharyngeal epithelium. Herein, we demonstrate that DNP induces heat-shock protein (HSP) 70-2 expression in NPC cells (6-10B) at a non-cytotoxic concentration. DNP induced HSP70-2 expression in a dose- and time- dependent manner, but showed no effect ...
متن کاملKinetics study of endogenous heat shock protein 70 expression.
The purpose of this study was to determine the kinetics of HSP70 expression in response to mild thermal stress. The rationale is to produce a basis for design of optimal heating methods to induce HSP70 expression for preconditioning in cardiac surgery. Bovine aortic endothelial cells were heated at 42 degrees C for 0.5 to 5 hours followed by 37 degrees C recovery for 1 to 48 hours. Quantitative...
متن کاملInsulin potentiates expression of myocardial heat shock protein 70.
OBJECTIVE Since insulin stimulates nitric oxide (NO) production and an increase in NO following heat shock is required for myocardial heat shock protein 70 (Hsp70) synthesis, we hypothesized that insulin would enhance myocardial Hsp70 synthesis by augmenting NO signaling. We examined whether a physiologic dose of insulin increased myocardial Hsp70 in unstressed and heat shock treated rats. ME...
