circRNA-disease information
Expression pattern:
UP
Associated gene: ANTXR 1 / ANTXR1
Associated microRNA: miR-6894-5p
Biological function: circAFF2 promotes gastric cancer cell proliferation, migration, invasion, and tumor growth in vivo; knockdown of circAFF2 suppresses these malignant phenotypes.
Molecular mechanism: circAFF2 acts as a sponge for miR-6894-5p and regulates/activates ANTXR 1 expression, forming the circAFF2/miR-6894-5p/ANTXR1 axis in gastric cancer progression.
Biological pathway or process:

ceRNA regulation (promotes); proliferation (promotes); migration (promotes); invasion (promotes); other pathway/process (promotes)

Detected method:
Q
M
Validation methods:

Sanger Sequencing; Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; RT-qPCR; Microarray; Clinical Sample Validation; Transfection; CCK8; Transwell Assay; Luciferase Reporter Assay; Bioinformatics Analysis; Western Blot; IHC (Immunohistochemistry); In Vivo Animal Model

Clinical significance:

Upregulated circAFF2 expression was relevant to depth of tumor invasion, TNM stage, and tumor size, and circAFF2 may act as a potential new biomarker and therapeutic target of gastric cancer.

Description:

circAFF2 is up-regulated in gastric cancer tissues, plasma, and cell lines. It promotes GC cell proliferation, migration, invasion, and xenograft tumor growth by sponging miR-6894-5p and relieving repression of ANTXR1. Its expression is associated with tumor invasion depth, TNM stage, and tumor size, suggesting biomarker and therapeutic-target potential.

Confidence score:

0.8314
