circRNA-disease information
Expression pattern:
UP
Associated gene: IGF1R, Ago2
Associated microRNA: miR-98-5p
Biological function: Promotes PDGF-BB-induced airway smooth muscle cell proliferation and migration, enhances inflammatory factor secretion, and inhibits apoptosis in an asthma cell remodeling model.
Molecular mechanism: Acts as a miRNA sponge for miR-98-5p, thereby regulating IGF1R expression/signaling in PDGF-BB-stimulated ASMCs.
Biological pathway or process:

proliferation (promotes); migration (promotes); apoptosis (inhibits); inflammation (promotes); ceRNA regulation (promotes)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Transfection; CCK8; Transwell Assay; Annexin V/PI Flow Cytometry; Western Blot; ELISA; Luciferase Reporter Assay; RNA Pull-Down; RIP (RNA Immunoprecipitation); Bioinformatics Analysis

Clinical significance:

circERBB2 is upregulated in bronchial biopsy samples from asthma patients and is proposed as a therapeutic target for asthma.

Description:

circERBB2 is upregulated in bronchial biopsy samples from asthma patients and in PDGF-BB-stimulated human ASMCs. Functionally, circERBB2 promotes ASMC proliferation/migration and inflammatory responses while suppressing apoptosis by sponging miR-98-5p and thereby increasing IGF1R expression/signaling.

Confidence score:

0.7289
