MiR-55-5p, miR-193b-5p, miR-200b-3p and miR-3175 were recently studied as molecules involved in cellular pathways such as PI3K/AKT [31] (“phosphatidylinositol-3-kinase” [32]/“protein kinase B” [33]), Ras [31] (“Rat sarcoma” [34]), MAPK [31] (“mitogen-activated protein kinase” [35]). The gene discussed is WNK2; the disease is sarcoma.
