Fig. 1From: MLH1–93 G/a polymorphism is associated with MLH1 promoter methylation and protein loss in dysplastic sessile serrated adenomas with BRAFV600E mutationMLH1 immunohistochemistry for a sessile serrated adenoma with a focus of dysplasia. The dysplastic portion of the SSA (left) has marked loss of nuclear MLH1 expression, in contrast to the remainder of the lesion where MLH1 expression is retainedBack to article page
