RESUMO
Long non-coding RNAs(lncRNAs)is a functional RNA molecule with a sequence length greater than 200 nucleo-tides that is not translated into a protein. LncRNA is of great value in the clinical application of malignant tumors and is closely related to the diagnosis,prevention,treatment and prognosis of tumors. CCAT1(human colon cancer associated transcript-1)can play a carci-nogenic role by promoting cell proliferation,invasion and migration. CCAT1 can be used as a biomarker for tumor prognosis. In this re-view,the research progress on the relationship between CCAT1 and digestive system malignant tumors is reviewed in recent years,the current status and prospects of malignant tumor treatment by CCAT1 are discussed.
RESUMO
Recent in vitro and in vivo experiments have revealed that ellagic acid and its metabolites can inhibit the growth of digestive system malignant tumor cells by inhibiting tumor cell proliferation,inducing apoptosis,breaking DNA binding to carcinogens,blocking virus infection,disturbing inflammation,angiogenesis and drug-resistance processes required for tumor metastasis.Ellagic acid and its metabolites are potential chemoprevention and therapeutic drugs against human cancers.
