Fig 1: POLRMT expression is elevated in skin SCC.POLRMT mRNA and protein expression as well as NDUFB8, UQCRC2 and COXI mRNA expression in skin SCC tumor tissues (“Tum”) and matched adjacent normal skin tissues (“Nor”) from a set of twenty (n = 20) primary skin SCC patients was tested by qRT-PCR and Western blotting assays (A–C). POLRMT mRNA and protein expression in the listed skin SCC cells, primary human skin fibroblasts (“Fibroblasts”) and keratinocytes (“Keratinocytes”) was tested (D–F). Data were mean ± standard deviation (SD). *P < 0.05 versus “Nor” tissues/“Fibroblasts”.
