"cMras was a sponge of miRNA-567 and released its direct target PTPRG. cMras overexpression decreased miR-567 expression and subsequently increased PTPRG expression while increased miRNA-567 expression blocked the effects induced by cMras. Moreover PTPRG was downregulated in lung adenocarcinoma and patients with low PTPRG expression exhibited significantly poor prognosis."xsd:string
