Annotated Information
Name
CERNA2:competing endogenous lncRNA 2 for microRNA let-7b
HOST2[1]
Characteristics
HOST2 is a novel member of the family of long non-coding mRNA-like genes, 2.9 kb in length, without an obvious open reading frame (ORF)[1]
Function
HOST2 promotes tumor cell migration, invasion and proliferation in epithelial ovarian cancer [1]. HOST2 harbors a let-7b binding site and inhibits let-7b functions post-transcriptionally, thus regulating cell growth and motility [1].
In human hepatocellular carcinoma (HCC) cell line SMMC-7721, HOST2 is found to promote cell proliferation, migration and invasion, and inhibit cell apoptosis [2].
Regulation
Let-7b can bind to HOST2 and represse HOST2 expression in EOC [1].
Disease
Ovarian cancer[1]
Hepatocellular carcinoma[2]
Expression
HOST2 is obviously upregulated in an EOC-derived cell line, OVCAR-3, compared with the other tested cell lines, including MKN28, Huh-7, HepG2, McF-7, DU145, A357, MG63, Hep-2, ARK2 and HeLa [1].
In hepatocellular carcinoma (HCC) tissues, the expression of HOST2 is up-regulated by approximately 2–10 times [2], and expression level of HOST2 is correlated with the size, quantity, distant metastasis and American Joint Committee on Cancer (AJCC) staging and differentiation degree of the tumour [2].
