MSH6 and cancer: Pairwise comparison of transcript levels representing MMR and microRNA genes revealed an inverse correlation between hMSH6 with hsa-miR-155 (r = -0.564; P value = 0.036) & hsa-miR-21 (r = -0.527; P value = 0.044) and between hMLH1 with that of hsa-miR-155 (r = -0.602; P value = 0.023) and hsa-miR-141 (r = -0.531; P value = 0.049) only in cancer tissues (S4 Fig).
