circRNA-disease information
Expression pattern:
UP
Associated gene: NLRC5
Associated microRNA: miR-4319
Biological function: promotes EC cell proliferation, invasion, and migration
Molecular mechanism: circATXN7 acts as a cytoplasmic ceRNA that binds and competitively inhibits miR-4319, thereby increasing NLRC5 expression and promoting EC progression
Biological pathway or process:

proliferation (promotes); invasion (promotes); migration (promotes); EMT (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RNase R Treatment; RT-qPCR; FISH / smFISH; Nuclear-Cytoplasmic Fractionation; Clinical Sample Validation; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; Colony Formation Assay; Transwell Assay; Western Blot; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

potential therapeutic target for treating EC

Description:

circATXN7 is up-regulated in esophageal cancer tissues and cell lines and mainly localizes in the cytoplasm. It promotes EC cell proliferation, invasion, migration, and xenograft tumor growth by acting as a ceRNA for miR-4319 and thereby increasing NLRC5 expression. Knockdown of circATXN7 suppresses EC growth in vivo and supports circATXN7 as a potential therapeutic target.

Confidence score:

0.7884
