circRNA-disease information
Expression pattern:
UP
Associated gene: NRAS
Associated microRNA: miR-892a
Biological function: Promotes NSCLC cell proliferation, viability, migration, invasion, EMT, and tumor growth in vivo; knockdown suppresses these malignant phenotypes.
Molecular mechanism: circ_0006528 acts as a miR-892a sponge and positively regulates NRAS expression, forming a circ_0006528/miR-892a/NRAS regulatory mechanism in NSCLC.
Biological pathway or process:

proliferation (promotes); migration (promotes); invasion (promotes); EMT (promotes); ceRNA regulation (other)

Detected method:
Q
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; RT-qPCR; Clinical Sample Validation; Transfection; MTT; Transwell Assay; Wound Healing Assay; Western Blot; Luciferase Reporter Assay; RNA Pull-Down; RIP (RNA Immunoprecipitation); In Vivo Animal Model; IHC (Immunohistochemistry); Survival Analysis; Bioinformatics Analysis

Clinical significance:

High circ_0006528 expression is associated with short survival time, tumor node and metastasis stage, and lymph node metastasis in NSCLC patients.

Description:

circ_0006528 is up-regulated in NSCLC tissues and cell lines and high expression is associated with poor prognosis. Functionally, circ_0006528 promotes NSCLC proliferation, migration, invasion, EMT, and xenograft tumor growth. Mechanistically, it sponges miR-892a to positively regulate NRAS expression.

Confidence score:

0.859
