circRNA-disease information
Expression pattern:
UP
Associated gene: FUS, FOXR2
Associated microRNA: -
Biological function: Promotes paclitaxel chemoresistance, cell viability, proliferation and tumor growth; inhibits PTX-induced cytotoxicity and apoptosis; supports FOXR2 expression and mRNA stability.
Molecular mechanism: circANKRD17 interacts with the RNA-binding protein FUS and recruits it to FOXR2, enhancing FOXR2 mRNA stability and increasing FOXR2 expression, thereby promoting PTX chemoresistance.
Biological pathway or process:

drug resistance (promotes); chemoresistance (promotes); proliferation (promotes); apoptosis (inhibits); cell cycle (other); mRNA stability (promotes)

Detected method:
Q
M
Validation methods:

Actinomycin D / DRB Stability Assay; RNase R Treatment; RT-qPCR; Microarray; Clinical Sample Validation; Cohort Study; Survival Analysis; Bioinformatics Analysis; Transfection; CCK8; MTT; Colony Formation Assay; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Nuclear-Cytoplasmic Fractionation; FISH / smFISH; RNA Pull-Down; RIP (RNA Immunoprecipitation); Western Blot; In Vivo Animal Model; IHC (Immunohistochemistry)

Clinical significance:

High circANKRD17 expression was correlated with PTX resistance and poor prognosis; patients with high expression displayed shorter overall survival.

Description:

circANKRD17 is up-regulated in ovarian cancer, especially PTX-resistant tissues and cell lines, and high expression is associated with poorer overall survival. It promotes paclitaxel chemoresistance and tumor growth by interacting with the RNA-binding protein FUS to stabilize FOXR2 mRNA and increase FOXR2 expression.

Confidence score:

0.8743
