Figure 4From: MicroRNA expression profile in head and neck cancer: HOX-cluster embedded microRNA-196a and microRNA-10b dysregulation implicated in cell proliferation Ki67 proliferation marker was detected by immunocytochemistry in keratinocytes. A significantly lower number of Ki67-positive cells were observed upon over-expression of the miR-196a (*p < 0.05). The bars represent standard deviation and t-test was used for statistical analysis.Back to article page
