circRNA-disease information
Expression pattern:
DN
Associated gene: FOXO1, PCNA, Bcl-2, Bax, Ki67
Associated microRNA: miR-942-5p
Biological function: circ_BLNK acts as a tumor suppressor in NSCLC, inhibiting proliferation, viability, colony formation, migration, invasion and tumor growth, while promoting apoptosis.
Molecular mechanism: circ_BLNK functions as a ceRNA/miRNA sponge for miR-942-5p, thereby indirectly increasing FOXO1 expression and suppressing NSCLC progression.
Biological pathway or process:

ceRNA regulation (promotes); proliferation (inhibits); migration (inhibits); invasion (inhibits); apoptosis (promotes); metastasis (inhibits)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Clinical Sample Validation; Nuclear-Cytoplasmic Fractionation; RNase R Treatment; Transfection; MTT; EdU Staining; Colony Formation Assay; Western Blot; Annexin V/PI Flow Cytometry; Transwell Assay; Luciferase Reporter Assay; Bioinformatics Analysis; In Vivo Animal Model; IHC (Immunohistochemistry)

Clinical significance:

Low expression of circ_BLNK predicts a poor prognosis and circ_BLNK may be a promising marker, therapeutic target, and diagnostic application for NSCLC.

Description:

circ_BLNK is down-regulated in NSCLC tissues and cells and behaves as a tumor suppressor. Its overexpression inhibits malignant phenotypes and xenograft tumor growth by sponging miR-942-5p and relieving repression of FOXO1, forming a circ_BLNK/miR-942-5p/FOXO1 regulatory axis with potential diagnostic and therapeutic relevance.

Confidence score:

0.7955
