circRNA-disease information
Expression pattern:
UP
Associated gene: TNFAIP8, AGO2
Associated microRNA: miR-34a-5p
Biological function: Promotes DDP resistance and malignant phenotypes (proliferation, migration, invasion) and inhibits apoptosis/cell cycle arrest in DDP-resistant NSCLC; promotes xenograft tumor growth.
Molecular mechanism: Acts as a ceRNA/miRNA sponge for miR-34a-5p, thereby regulating TNFAIP8 expression and DDP-resistant NSCLC progression.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; Nuclear-Cytoplasmic Fractionation; Luciferase Reporter Assay; RIP (RNA Immunoprecipitation); Transfection; CCK8; Colony Formation Assay; Annexin V/PI Flow Cytometry; Cell Cycle Assay; Transwell Assay; Western Blot; In Vivo Animal Model; IHC (Immunohistochemistry); Bioinformatics Analysis; Clinical Sample Validation

Clinical significance:

Provides a potential target for DDP-resistant NSCLC diagnosis and treatment.

Description:

circHUWE1 is upregulated in NSCLC, particularly in cisplatin (DDP)-resistant tissues/cells. It promotes DDP resistance and malignant behaviors by sponging miR-34a-5p and derepressing TNFAIP8, and its knockdown suppresses xenograft growth.

Confidence score:

0.8571
