Proteasome inhibitor mg 132
WebbMG-132 is a proteasome inhibitor that exhibits anti-fibrotic and anti-osteoarthritic activities. In renal interstitial fibroblasts, MG-132 inhibits proliferation and induces apoptosis by activating p53, p21, caspase 3, and Bax. WebbBiological Activity. MG132 is a potent cell-permeable inhibitor of proteasome and calpain with IC50 of 100 nM and 1.2 μM respectively. MG132 inhibited the growth of HeLa cells via inducing the cell cycle arrest as well as triggering apoptosis. MG132 also inhibits NF-κB activation with an IC50 of 3 µM and prevents β-secretase cleavage.

It is noticed that cyclin D1 levels were significantly rescued by the MG-132 co-treatment. α-Tubulin levels served as the control for equal loading; ( C ) Obatoclax …
WebbOverview. (S)-MG132 is a reversible, cell-permeable inhibitor of proteasome activity (IC₅₀ = 100 nM; Kisselev & Goldberg) and calpain (IC₅₀ = 1.2 µM; Tsubuki et al.). The ubiquitin-proteasome pathway selectively degrades intracellular proteins, thereby clearing damaged or misfolded proteins, and regulating the availability of key ... WebbFirst, the proteasome inhibitor MG-132 specifically inhibited CPT-induced but not ionizing radiation- or hydroxyurea-induced DSBs as revealed by both the neutral comet assay and measurements of the specific DNA damage signals (e.g. γ-H2AX, phosphorylated ataxia telangiectasia mutated (Ser-1981), and phosphorylated Chk2 (Ser-33/35)) that are …
WebbMG132 acts as a powerful apoptotic agent in several tumor cell lines, and much of the MG132 activity has been attributed to NF-κB inhibition through the inhibition of IκB degradation. 24 Since the degradation of inhibitors of κB proteins (IκBα and IκBβ) is essential for the canonical pathway of NF-κB activation and the aberrant expression of …
