MG-132

HeLa cells were transfected with control mimic, RMND5A siRNA or miR-138 mimic. After transfection for 36 h, cells were treated with proteasome inhibitor MG132 (20 uM) or Dimethyl sulfoxide (DMSO) for 8 h. Endogenous Exportin-5 protein and RMND5A protein expression was measured by western blotting.

HeLa cells were transfected with negative control mimic, miR-138 mimic or RMND5A siRNA. After transfection for 36 h, cells were treated with MG132 (20 uM) or DMSO for 8 h. RMND5A and Exportin-5 protein expression were analyzed by immunocytochemistry. Nuclei were counterstained with DAPI.

TFEB induced autophagy dependent ATZ clearance in vitro. MEF transiently co-transfected with either ATZ plus GFP expressing plasmids or ATZ plus TFEB expressing plasmids were incubated with proteasome inhibitor MG132 or with DMSO for 6 h. Upon MG132 treatment, steady state levels of 52 kDa ATZ band increased in both cells transfected with ATZ plus GFP and with ATZ plus TFEB expressing plasmids. Quantification of band intensities showed a 48% reduction of ATZ in cells transfected with ATZ plus TFEB compared to cells transfected with ATZ plus GFP, in the absence of the proteasome inhibitor. In MG132 treated cells, a 61% decrease of ATZ was detected in cells transfected with ATZ plus TFEB compared to cells transfected with ATZ plus GFP.

JAK1 expression was analyzed in A375 cells expressing scrambled shRNA or shRNF125 (#2) and treated with MG132 (5 uM, 10 hr), and in Lu1205 cells expressing WT RNF125 and treated with MG132.

LRB1 and LRB2 regulate phyB protein levels. PhyB protein levels in crude extracts from the wild type (WT) and the indicated mutant backgrounds were assayed by immunoblot analysis with anti-phyB monoclonal antibodies. Anti-PBA1 and anti-histone H3 antibodies were used to confirm equal protein loading. Rc-induced loss of phyB in the wild type is inhibited by 100 uM MG132.

Representative images for γ-H2AX-stained cells treated with 100 uM FA for 3 h without or with MG132. Fluorescence was measured in at least 50 nuclei in each of three experiments.

Nek2A impedes SuFu ubiquitination. HEK293T cells transfected with Nek2A-Myc and Flag-SuFu for 48 h were treated with MG-132 to enrich ubiquitinated proteins, and subsequently subjected to co-immunoprecipitation assay. Precipitated proteins were probed using anti-Ub antibody.

GSK-3β phosphorylation at Ser9 is enhanced in NOK-overexpressed stable cell lines. The proteasome inhibitor, MG132, was added in medium of HeLa-HA and HeLa-NOK-HA cells for 12 h and then the p-GSK-3b(Ser9) was assayed by western blotting.

Truncated mouse Period2 (Per2) protein was expressed in NIH3T3 cells, treated by cycloheximide with or without MG132 for 1-4 hours.Per2 was reported to be degraded by the proteasome proteolysis. By adding MG132 (25 μM), a proteasome inhibitor, the degradation of Per2 was dramatically decreased within 4 hours treatment (shown by western blot).
