Cancer&Entry Information
Cancer Name | hepatocellular cancer |
ICD-0-3 | NA |
Methods | circRIP, qRT-PCR, IN SITU HYBRIDIZATION, FLUORESCENCE IN SITU HYBRIDIZATION, IMMUNOHISTOCHEMISTRY |
Sample | HCC and paired adjacent liver tissues, HCC cell lines HepG2, SMMC-7721, QGY-7701, and SK-Hep1 |
Expression Pattern | down-regulated |
Function Description | we analyzed the expression profile of human circRNAs in HCC tissues and identified circMTO1 (mitochondrial translation optimization 1 homologue; hsa_circRNA_0007874/hsa_circRNA_104135) as one circRNA significantly down-regulated in HCC tissues. HCC patients with low circMTO1 expression had shortened survival. By using a biotin-labeled circMTO1 probe to perform RNA in vivo precipitation in HCC cells, we identified miR-9 as the circMTO1-associated miRNA. Furthermore, silencing of circMTO1 in HCC could down-regulate p21, the target of oncogenic miR-9, resulting in the promotion of HCC cell proliferation and invasion. In addition, the tumor-promoting effect of circMTO1 silencing was blocked by miR9 inhibitor. Intratumoral administration of cholesterol-conjugated circMTO1 small interfering RNA promoted tumor growth in HCC-bearing mice in vivo. |
