circRNA-disease information
Expression pattern:
DN
Associated gene: AGO2, KDM4A, YAP1
Associated microRNA: miR-526b
Biological function: inhibits gastric cancer cell proliferation and invasion, promotes apoptosis, and acts as an anti-oncogene
Molecular mechanism: circ_SPECC1 adsorbs miR-526b and enhances the inhibitory effect of miR-526b on the downstream KDM4A/YAP1 pathway
Biological pathway or process:

Hippo/YAP (inhibits); proliferation (inhibits); invasion (inhibits); apoptosis (promotes); ceRNA regulation (other)

Detected method:
Q
Validation methods:

RT-qPCR; Nuclear-Cytoplasmic Fractionation; RNA Pull-Down; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; BrdU; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot; Bioinformatics Analysis

Clinical significance:

may provide new targets for the prevention and treatment of gastric cancer

Description:

circ_SPECC1 is down-regulated in gastric cancer cell lines and functions as a tumor suppressor by inhibiting proliferation and invasion while promoting apoptosis. Mechanistically, it binds miR-526b and enhances miR-526b-mediated inhibition of the KDM4A/YAP1 pathway, suggesting potential therapeutic relevance in gastric cancer.

Confidence score:

0.6853

Other information
Title:

Circ_SPECC1 enhances the inhibition of miR-526b on downstream KDM4A/YAP1 pathway to regulate the growth and invasion of gastric cancer cells.
