circRNA-disease information
Expression pattern:
UP
Associated gene: CCL4, CCR5, Ago2
Associated microRNA: miR-125a-3p
Biological function: promotes proliferation, colony formation and invasion; promotes tumor growth in vivo
Molecular mechanism: acts as a sponge of miR-125a-3p to upregulate the CCL4-CCR5 axis
Biological pathway or process:

proliferation (promotes); invasion (promotes); ceRNA regulation (promotes)

Detected method:
Q
H
Validation methods:

FISH / smFISH; RT-qPCR; divergent primers PCR; RNase R Treatment; Actinomycin D / DRB Stability Assay; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; CCK8; Colony Formation Assay; Transwell Assay; Western Blot; In Vivo Animal Model; H&E Staining; IHC (Immunohistochemistry); Clinical Sample Validation; Survival Analysis; Bioinformatics Analysis

Clinical significance:

circ_0002483 expression was associated with TNM stage and poor survival in patients with LUAC

Description:

hsa_circ_0002483 (circ_0002483; circPTK2) is up-regulated in LUAC and correlates with advanced TNM stage and poorer overall survival. Functionally, it promotes LUAC cell proliferation and invasion and enhances xenograft growth. Mechanistically, it sponges miR-125a-3p, relieving repression of the CCL4-CCR5 axis.

Confidence score:

0.8711
