Figure Lengend Snippet: H2/Z14 and C6/Z96 modulate SDH subunit protein abundance.( a ) Normalized expression of SDHA , SDHB , SDHC , and SDHD across human lung adenocarcinoma (LUAD, N=80) and immortalized lung epithelial & fibroblast cell lines (Lung, N=8) from the Human Protein Atlas database. Expression levels are presented as normalized transcript per million (nTPM), b,c Immunofluorescent staining ( b ) and quantification ( c ) of SDHA and SDHD in H1975 cells treated with or without H2/Z14 and C6/Z96 (30 µM) for six hours. Cells were co-stained with primary anti-SDHA and anti-SDHD antibodies, followed by secondary antibodies conjugated with Alexa Fluor 488 or 555. The cells were then counterstained with DAPI and imaged by confocal microscopy. Scale bar = 20 µm. N = 6 replicates. ( d ) Western blot analysis of SDHA in H1975 cells treated with or without H2/Z14 and C6/Z96 (30 µM) for four hours. Band intensity was quantified and is shown below the images. β-Actin was used as a loading control. The images were representative of data from two independent experiments. Data are mean ± s.e.m. and were analyzed with Welch’s t-test ( a , c ). **, p <0.01; ***, p <0.001; ns, not significant
