Article Title: Alternative splicing of Mff regulates AMPK-mediated phosphorylation, mitochondrial fission and antiviral response.

doi: 10.1016/j.phrs.2024.107414

Figure Lengend Snippet: Fig. 2. Multiple assays for AMPK-mediated Mff phosphorylation in MEFs in response to mitochondrial energetics. (a–c) Conventional SDS-PAGE and immunoblot analysis of Mff and AMPK phosphorylation in WT MEFs. The indicated letters (a, b, c) correspond to the endogenous Mff bands observed in WT MEFs. (a) WT MEFs were treated with increasing concentrations of oligomycin (10 pM, 100 pM, 1 nM, 10 nM, 100 nM, and 1 μM) for 30 min. Mff band shift (band c to b) was detected by anti-Mff antibodies. Mff KO MEFs were used as negative control. (b) WT MEFs were treated with oligomycin (1 and 0.3 μM) for 30 min. Phosphorylation of endogenous Mff was detected using an anti-phospho-Mff (S146) antibody. (c) WT MEFs were treated with 20 μM CCCP for the indicated times and harvested with or without washout. The activation of AMPK signaling was confirmed by phosphorylation of AMPKα at Thr172 or ACC at Ser79 using specific antibodies. (d–f) Conventional SDS-PAGE or Phos-tag SDS-PAGE and immunoblot analysis of Mff in Mff KO MEFs stably expressing FLAG-tagged Mff isoform 4. Black and white arrowheads indicate phospho-Mff and unphospho-Mff in SDS-PAGE or AMPK-phospho-Mff and AMPK-unphospho-Mff in Phos-tag SDS-PAGE, respectively. (d) Mff KO MEFs stably expressing FLAG-tagged Mff isoform 4 were treated with 20 μM CCCP and harvested with or without washout. *Non-specific band. (e, f) Phos-tag SDS-PAGE analysis of Mff in response to AMPK activity. Mff KO MEFs stably expressing FLAG-tagged Mff isoform 4 WT (e, f) or S146A mutant (f) were treated with 2 mM AICAR or 20 μM compound C (Comp. C) for 2 h. The response of Mff to AMPK signaling was analyzed by Phos-tag SDS-PAGE. Mff KO MEFs were used as negative control. *Non-specific band.

Article Title: Hepatic steatosis induced by nicotine plus Coca-Cola™ is prevented by nicotinamide riboside (NR)

doi: 10.3389/fendo.2024.1282231

Figure Lengend Snippet: Nic plus Coke administration increases the lipogenesis marker in the liver. (A) Representative western blot analysis of SREBP1 cleavage (SREBP1c). β-Actin levels are shown as a loading control. Molecular weight markers are depicted in KDa. (B) Quantification of the western blot of SREBP1c. (C) Representative western blot analysis of p-ACC. β-Actin levels are shown as a loading control. Molecular weight markers are depicted in KDa. (D) Quantification of the western blot of p-ACC. Protein levels of SREBP1c and p-ACC were normalized to β-Actin and expressed as the mean ± S.E.M. (the fold of change relative to the control). n= 5 - 6 per group. Statistical difference is indicated by * compared to Sal+Water vs Nic+Coke (P< 0.05).
