Figure Lengend Snippet: OTUD1 deubiquitinates PGAM5. (A) Representative western blot of Pgam5 protein in heart of Flox and Otud1-CKO mice subjected to Sham or TAC (n=3). (B) Representative western blotting result of Pgam5 in NRCMs infected with Ad-GFP and Ad-Otud1 and treated with Ang II (10 μM) for 48h and cycloheximide (CHX, 50 μM) for the indicated time points (n=3). (C) Results of ubiquitination assays confirming the ubiquitination of PGAM5 after overexpression of OTUD1 for 48 h and treated with MG132 (50 μM) for 6 h in 293T. (D) Results of ubiquitination assays confirming the K48 ubiquitination of PGAM5 after co-transfected with Flag-OTUD1, HA-Ub-WT, HA-Ub-K48, HA-Ub-K63 for 24 h and treatment with MG132 (50 μM) for 6 h in 293T. (E) Results of ubiquitination assays confirming the expression and ubiquitination of Pgam5 in NRCMs infected with Ad-GFP and Ad-Otud1 and followed by Ang Ⅱ treatment. (F) Results of ubiquitination assays confirming the expression and ubiquitination of Pgam5 in heart tissue from Flox and CKO mice subjected to sham or TAC. (G) Results of ubiquitination assays confirming the ubiquitination of Pham5 after overexpression of OTUD1, OTUD1(C320A) and Pgam5 for 24 h and treated with MG132 (50 μM) for 6 h in 293T cells. (H) Immunoblotting analysis of Pgam5, Ad-Otud1 and Ad-Otud1 (C294S) in NRCMs.
Article Snippet: To test the role of PGAM5 in pathological cardiac hypertrophy, we used PGAM5 inhibitor LFHP-1c (HY-139598, MCE) in TAC mice.
