circRNA-disease information
Expression pattern:
UP
Associated gene: -
Associated microRNA: -
Biological function: Associated with liver cancer stemness and poor prognosis; implicated in regulating EMT; did not significantly affect tumor growth in vivo upon overexpression.
Molecular mechanism: Included in a constructed ceRNA network and clinical correlation analyses, but specific miRNA/mRNA targets for circ-ZEB1 were not reported in the provided text.
Biological pathway or process:

EMT (other); 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:

Prognostic marker association: higher expression in HCC tissues and higher levels in poor differentiation; correlated with poor prognosis (stated).

Description:

circ-ZEB1 (hsa_circ_0004907) is enriched in liver CSC-derived exosomes and is up-regulated in HCC tumor tissues versus matched paraneoplastic tissues. It is reported as associated with stemness/poor prognosis and included in a ceRNA network analysis, but in vivo overexpression did not significantly alter xenograft tumor growth in the described experiments.

Confidence score:

0.6616
