doi: 10.1038/s41598-026-40414-9
Figure Lengend Snippet: FKBP51 overexpression decreases Mitofusin 2 protein levels in HepG2 cells. Cells were transfected with either a plasmid coding Myc-DDK-tagged human FKBP51 (FKBP51) or an empty pCMV6 plasmid (Control) and were stimulated for 3 h with 100 nM insulin, mtHSP70 was used as loading control. ( A ) Representative blot of proteins of mitochondrial dynamics ( n = 10), ( B ) Mitofusin 1 protein levels (MFN1), ( C ) Mitofusin 2 protein levels (MFN2), ( E ) Ratio LOPA/SOPA1, ( D ) Dynamin-related protein 1 (Drp1) phosphorylation, ( F ) Mitochondrial fission protein 1 (Fis1 protein levels), ( G ) Dynamin-related protein 1 (Drp1), protein levels, ( H ) Representative blot of mitochondrial oxidative phosphorylation chain (OXPHOS), ( I ) NADH: ubiquinone oxidoreductase subunit B8 (NDUFB8, complex I) protein level, J Succinate dehydrogenase iron-sulfur subunit (SDHB, complex II), ( K ) Ubiquinol-cytochome c reductase core protein 2 (UQCRC2, complex III), ( L ) Cytochrome c oxidase subuni1 (MTCO1, complex IV) and ( M ) ATP synthase subunit alpha (ATP5A, complex V) ( n = 8). One-way analysis of variance (ANOVA) followed by Tukey post hoc test. * p < 0.05 compared with control. Data are shown as means ± SEM.
Article Snippet: Cells were transfected with either a plasmid encoding Myc-DDK-tagged human FKBP51 or an empty pCMV6 plasmid (RC210608 and PS100001 , OriGene Technologies, Rockville, MD, USA), using Lipofectamine 2000® (11668019, Thermo Fisher Scientific) in opti-MEM (31985-070, Thermo Fisher Scientific) overnight.
