SPOTLIGHT REVIEW Proteasome inhibitors and cardiac cell growth
Activation of the ubiquitin-proteasome system has been described in different models of cardiac hypertrophy. Cardiac cell growth in response to pressure or volume overload, as well as physiological adaptive hypertrophy, is accompanied by an increase in protein ubiquitination, proteasome subunit expression, and proteasome activity. Importantly, an inhibition of proteasome activity prevents and r...
متن کاملProteasome inhibitors attenuated cholesterol-induced cardiac hypertrophy in H9c2 cells
The Ubiquitin proteasome system (UPS) plays roles in protein degradation, cell cycle control, and growth and inflammatory cell signaling. Dysfunction of UPS in cardiac diseases has been seen in many studies. Cholesterol acts as an inducer of cardiac hypertrophy. In this study, the effect of proteasome inhibitors on the cholesterol-induced hypertrophic growth in H9c2 cells is examined in order t...
متن کاملProteasome Inhibitors And
Protein degradation plays an important role in the control and regulation of many crucial biological functions, ranging from cell cycle progression to presentation of viral antigens for scrutiny by cells of the immune system. At the heart of many of these catabolic events is the multicatalytic proteinase complex known as the proteasome. This large barrel-shaped protein complex executes a remark...
متن کاملMultiple cardiac proteasome subtypes differ in their susceptibility to proteasome inhibitors.
AIMS The proteasome is the proteolytically active core of the ubiquitin-proteasome system, which regulates vital processes and which can cause various diseases when it malfunctions. Therefore, the proteasome has become an attractive target for pharmaceutical interventions. Inhibition of the cardiac proteasome by specific proteasome inhibitors has been shown to attenuate cardiac hypertrophy and ...
متن کاملDesign, Synthesis and Evaluation of Substituted Aryl-2-Nitrovinyl Derivatives as Small Molecules Proteasome Inhibitors
Based on the existing structure activity relationship for proteasome inhibitors, a number of substituted aryl-2-nitrovinyl derivatives have been synthesized as Michael acceptor and their cytotoxicity and proteasome inhibitory effects were evaluated on two cancer cell lines. Compound 2d exhibited IC50 values of 0.71 and 17.79 μM comparable to bortezomib against MCF-7 and PC-3, respectively. The ...
