circRNA-disease information
Expression pattern:
UP
Associated gene: PVT1, EIF4A3, LMNB2
Associated microRNA: -
Biological function: promotes proliferation, migration, invasion and EMT in LUAD
Molecular mechanism: PVT1 recruits EIF4A3 to promote circLMNB2 biogenesis/expression; EIF4A3 binds circLMNB2
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); EMT (promotes); other pathway/process (other)

Detected method:
Q
Validation methods:

RT-qPCR; Nuclear-Cytoplasmic Fractionation; RIP (RNA Immunoprecipitation); Transfection; CCK8; Transwell Assay; Western Blot; Clinical Sample Validation; Survival Analysis; ROC Analysis; Bioinformatics Analysis; In Vivo Animal Model

Clinical significance:

circLMNB2 had diagnostic value for LUAD and high circLMNB2 expression was associated with shorter survival time (poor prognosis).

Description:

circLMNB2 is up-regulated in LUAD and functions as an oncogenic circRNA that promotes LUAD cell proliferation, migration and invasion. Mechanistically, PVT1 recruits the RBP EIF4A3 to facilitate circLMNB2 generation/expression, and circLMNB2 overexpression rescues the inhibitory phenotypes caused by PVT1/EIF4A3 knockdown. High circLMNB2 is associated with diagnostic value and poorer survival in LUAD.

Confidence score:

0.7617
