UP
Associated gene: CD133, E-cadherin, EpCAM, Ki67
Associated microRNA: -
Biological function: Promotes tumor growth in vivo; enhances liver cancer cell stemness and EMT; associated with poor prognosis.
Molecular mechanism: Included in a ceRNA network and public-database-based analyses; specific miRNA/mRNA targets for circ-AFAP1 were not reported in the provided text.
Biological pathway or process:

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

Detected method:
Q
S
Validation methods:

RNA-seq; RT-qPCR; Clinical Sample Validation; Bioinformatics Analysis; Transfection; In Vivo Animal Model; Western Blot; IHC (Immunohistochemistry)

Clinical significance:

Higher expression in HCC tissues vs paraneoplastic tissues; higher in poor differentiation vs well differentiation; stated as prognostic marker and correlated with poor prognosis.

Description:

circ-AFAP1 (hsa_circ_0069152), derived from liver CSC exosomes, is up-regulated in HCC tumor tissues and associated with stemness features and poor prognosis. Functionally, circ-AFAP1 overexpression increases xenograft tumor volume and modulates stemness/EMT markers (e.g., increased CD133 with decreased E-cadherin and EpCAM), supporting a role in promoting HCC progression via enhancing stemness and EMT.

Confidence score:

0.6616
