Fig. 2From: Krüppel-like factor 4 expression in oral carcinoma cells and hypermethylation at the gene promoterMethylation of KLF4 gene promoter. a Position of methylation-susceptible cytosines in the promoter is indicated as blue (upper line) and the cytosines are numerically numbered from #1 to #109. Lower lines show cytosines that were entirely methylated (black) or unmethylated (white) and mixture of methylation and unmethylation (gray). M% and U/M% indicate percentage of methylated cytosines and the mixture in 39 cytosines, respectively. b Sequence data on #10 and #11 cytosines. Four carcinoma cell lines containing methylated (M) and unmethylated (U) cytosines and the mixture (U/M) were presented as an exampleBack to article page
