circRNA-disease information
Expression pattern:
UP
Associated gene: MAPK8, EIF4A3, AGO2
Associated microRNA: miR-214-3p
Biological function: Promotes migration and invasion of NSCLC cells.
Molecular mechanism: circTADA2A sponges miR-214-3p to up-regulate MAPK8 and recruits EIF4A3 to stabilize MAPK8 mRNA.
Biological pathway or process:

migration (promotes); invasion (promotes); ceRNA regulation (promotes); mRNA stability (promotes)

Detected method:
Q
M
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; RT-qPCR; FISH / smFISH; RIP (RNA Immunoprecipitation); RNA Pull-Down; Luciferase Reporter Assay; Transfection; Wound Healing Assay; Transwell Assay; Western Blot; Bioinformatics Analysis

Clinical significance:

circTADA2A might serve as a novel potential biomarker for NSCLC.

Description:

circTADA2A is highly expressed in NSCLC cells and functions as an oncogenic circRNA that promotes migration and invasion. Mechanistically, it up-regulates MAPK8 through two routes: sponging miR-214-3p in a ceRNA manner and recruiting the RBP EIF4A3 to stabilize MAPK8 mRNA.

Confidence score:

0.7785

Other information
Title:

CircTADA2A up-regulates MAPK8 by targeting MiR-214-3p and recruiting EIF4A3 to promote the invasion and migration of non-small cell lung cancer cells.
