SNHG20 and hepatocellular carcinoma: Most of the lncRNAs studied in OC also act to either activate (HOXB-cluster antisense RNA-3—HOXB-AS3; associated with poor prognosis of hepatocellular carcinoma—AWPPH; metastasis-associated lung adenocarcinoma-1—MALAT1; colon cancer-associated transcript-2—CCAT2; small nucleolar RNA host gene-20—SNHG20) or deactivate (HOXD-cluster antisense RNA-1—HOXD-AS1) the Wnt-signaling pathway [327,328,329,330,331,332].
