circRNA-disease information
Expression pattern:
DN
Associated gene: PTEN, PI3K/AKT pathway, Ago2
Associated microRNA: miR-21-5p
Biological function: Overexpression of circDDX17 enhanced sorafenib sensitivity, promoted apoptosis, inhibited EMT, reduced tumor growth, and suppressed HCC tumorigenesis.
Molecular mechanism: circDDX17 acts as a miR-21-5p sponge and regulates the miR-21-5p/PTEN/PI3K/AKT axis to suppress sorafenib resistance and HCC progression.
Biological pathway or process:

PI3K/AKT (inhibits); apoptosis (promotes); EMT (inhibits); proliferation (inhibits); drug resistance (inhibits); chemoresistance (inhibits); ceRNA regulation (other)

Detected method:
Q
Validation methods:

RNase R Treatment; RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Transfection; CCK8; Annexin V/PI Flow Cytometry; Western Blot; In Vivo Animal Model

Clinical significance:

circDDX17 may provide novel biomarkers for the diagnosis, treatment and prognosis of HCC; circDDX17 expression was positively associated with HBV infection.

Description:

circDDX17 is down-regulated in HCC tissues and cell lines. Its overexpression suppresses HCC tumorigenesis, reduces sorafenib resistance, promotes apoptosis, and inhibits EMT, partly through the miR-21-5p/PTEN/PI3K/AKT regulatory axis.

Confidence score:

0.7581
