circRNA-disease information
Expression pattern:
UP
Associated gene: FAM83A, MEMO1, Ago2, OCT4, NANOG
Associated microRNA: miR-1253
Biological function: Promotes NSCLC cell proliferation, stemness, and tumor growth; exosomal circ_0007385 facilitates NSCLC cell proliferation and stemness.
Molecular mechanism: Exosomal circ_0007385 acts as a sponge for miR-1253 and positively regulates FAM83A expression, thereby promoting NSCLC cell proliferation and stemness.
Biological pathway or process:

proliferation (promotes); stemness (promotes); ceRNA regulation (promotes); other pathway/process (promotes)

Detected method:
Q
Validation methods:

RNase R Treatment; RT-qPCR; Clinical Sample Validation; Nuclear-Cytoplasmic Fractionation; RIP (RNA Immunoprecipitation); RNA Pull-Down; Luciferase Reporter Assay; Transfection; CCK8; EdU Staining; Colony Formation Assay; Western Blot; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

Exosomal circ_0007385 might be a promising application in NSCLC diagnosis and treatment.

Description:

circ_0007385 is upregulated in NSCLC tissues and cells and is also delivered by NSCLC-derived exosomes. It promotes NSCLC cell proliferation, colony formation, sphere formation, stemness marker expression, and tumor growth by sponging miR-1253 and relieving repression of FAM83A. The study suggests exosomal circ_0007385 may have potential value for NSCLC diagnosis and treatment.

Confidence score:

0.7977
