circRNA-disease information
Expression pattern:
DN
Associated gene: BCL-2
Associated microRNA: miR-544a-3p
Biological function: Suppresses gastric cancer progression by inhibiting proliferation, migration, invasion, and cell-cycle progression, promoting apoptosis, and inhibiting autophagy.
Molecular mechanism: Acts as a cytoplasmic sponge of miR-544a-3p to regulate the miR-544a-3p/BCL-2 axis, thereby inhibiting autophagosome formation and affecting malignant phenotypes.
Biological pathway or process:

autophagy (inhibits); proliferation (inhibits); migration (inhibits); invasion (inhibits); apoptosis (promotes); cell cycle (inhibits); ceRNA regulation (other)

Detected method:
Q
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; RT-qPCR; Nuclear-Cytoplasmic Fractionation; FISH / smFISH; Luciferase Reporter Assay; Transfection; CCK8; Colony Formation Assay; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Transwell Assay; Western Blot; IF (Immunofluorescence); In Vivo Animal Model; IHC (Immunohistochemistry); H&E Staining; Bioinformatics Analysis

Clinical significance:

Its expression correlated with tumor invasion depth (tumor depth).

Description:

hsa_circ_0009109 (circDCAF6_003) is down-regulated in gastric cancer tissues and cell lines and acts as a tumor suppressor. It mainly localizes to the cytoplasm, sponges miR-544a-3p, upregulates BCL-2, and inhibits autophagy, thereby restraining proliferation, migration/invasion, and tumor growth.

Confidence score:

0.8072
