Fig. 1From: Krüppel-like factor 4 expression in oral carcinoma cells and hypermethylation at the gene promoterExpression of KLF4 mRNA in oral carcinoma cell lines and normal keratinocytes (HaCaT). KLF4 expression was quantitatively examined by the real-time PCR. Relative expression was standardized by expression of ACTB in each sample (n = 4) and compared with the expression in HaCaT cellsBack to article page
