circRNA-disease information
Expression pattern:
UP
Associated gene: HOXC9
Associated microRNA: miR-495
Biological function: Promotes NSCLC cell proliferation, migration/invasiveness and tumor growth; acts as a tumor promoter.
Molecular mechanism: Acts as a ceRNA/miRNA sponge for miR-495, thereby relieving miR-495-mediated repression of HOXC9 (post-transcriptional regulation via HOXC9 3'-UTR).
Biological pathway or process:

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

Detected method:
Q
H
Validation methods:

RT-qPCR; FISH / smFISH; Clinical Sample Validation; Transfection; Luciferase Reporter Assay; CCK8; Colony Formation Assay; Transwell Assay; Western Blot; In Vivo Animal Model; IHC (Immunohistochemistry); Survival Analysis; Bioinformatics Analysis

Clinical significance:

High hsa_circ_0020123 expression correlates with lymph node invasiveness, TNM stage, tumor size, and low overall survival; may be a prognostic marker in NSCLC.

Description:

hsa_circ_0020123 is up-regulated in NSCLC tissues and cell lines and mainly localizes to the cytoplasm. It promotes NSCLC proliferation, migration/invasion and xenograft tumor growth by sponging miR-495 and thereby increasing HOXC9 expression, forming a hsa_circ_0020123/miR-495/HOXC9 axis. High expression associates with worse overall survival, supporting a prognostic/therapeutic relevance.

Confidence score:

0.7628

Other information
Title:

High hsa_circ_0020123 expression indicates poor progression to non-small cell lung cancer by regulating the miR-495/HOXC9 axis.
