Expression
Description  circMTO1 expression was consistently and significantly decreased in HCC tumor tissues as compared to that in matched nontumor liver tissues.Decreased circMTO1 expression is significantly correlated with poor prognosis of HCC patients.
Method    microarray, qRT-PCR
Sample    hepatocellular carcinoma tumor tissues, nontumor liver tissues

Function
Description  circMTO1 suppresses HCC progression by acting as the sponge of oncogenic miR-9 to promote p21 expression, suggesting that circMTO1 is a potential target in HCC treatment. The decrease of circMTO1 in HCC tissues may serve as a prognosis predictor for poor survival of patients.
Method    -
in vitro    HepG2, SMMC-7721, QGY-7701, SK-Hep1
in vivo    HCC-bearing male nude mice model SMMCLTNM

Interaction
Target    miR-9
Type    circRNA-miRNA
Sample    HepG2 cells
Experiment    RNA pull-down
Description    circMTO1 can bind miR-9 in the cytoplasm.
ceRNA target    p21
