circRNA-disease information
Expression pattern:
UP
Associated gene: TRAF6, MAPK11, Ago2
Associated microRNA: miR-516a-5p, miR-145-5p
Biological function: Promotes HCC cell proliferation and tumor growth (tumorigenesis) in vitro and in vivo.
Molecular mechanism: Acts as a miRNA sponge (ceRNA) for miR-516a-5p (and miR-145-5p), thereby derepressing miR-516a-5p targets TRAF6 and MAPK11; involves Ago2/RISC.
Biological pathway or process:

proliferation (promotes); MAPK (other); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

Microarray; Bioinformatics Analysis; RT-qPCR; divergent primers PCR; RNase R Treatment; Transfection; MTT; Colony Formation Assay; In Vivo Animal Model; Luciferase Reporter Assay; RNA Pull-Down; RIP (RNA Immunoprecipitation); Western Blot; Clinical Sample Validation

Clinical significance:

Serum circ_0001955 is higher in HCC patients than healthy controls and decreases after surgery.

Description:

circ_0001955 is upregulated in HCC tissues and patient serum and functions as an oncogenic circRNA. It sponges miR-516a-5p (also predicted/implicated with miR-145-5p), thereby relieving repression of TRAF6 and MAPK11 and promoting HCC cell proliferation and xenograft tumor growth.

Confidence score:

0.8267

Other information
Title:

Circ_0001955 facilitates hepatocellular carcinoma (HCC) tumorigenesis by sponging miR-516a-5p to release TRAF6 and MAPK11.
