In ovarian cancer, MEIS1 phosphoprotein level (S194, S196 and T202) between tumor and normal tissues has no statistical differences, while the phosphorylation level of S196 in LUAD (p < 0.001), ccRCC (p < 0.001) and UCEC (p < 0.001) were higher in normal tissues compared to tumor tissues. The gene discussed is MEIS1; the disease is neoplasm.
