circRNA-disease information
Expression pattern:
UP
Associated gene: SOX4
Associated microRNA: miR-138-5p
Biological function: promotes proliferation, migration, invasion, and EMT in hepatocellular carcinoma cells
Molecular mechanism: Acts as a ceRNA by binding (sponging) miR-138-5p to upregulate its target gene SOX4, thereby promoting malignant behaviors and EMT.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Nuclear-Cytoplasmic Fractionation; Transfection; MTT; Transwell Assay; Western Blot; Luciferase Reporter Assay; Clinical Sample Validation; Bioinformatics Analysis

Clinical significance:

High intratumoral circ-TLK1 expression was closely associated with large tumor size, advanced TNM stage, and vascular invasion of HCC patients.

Description:

circ-TLK1 is up-regulated in hepatocellular carcinoma tissues and cell lines and mainly localizes to the cytoplasm. It promotes HCC proliferation, migration, invasion, and EMT by sponging miR-138-5p and thereby de-repressing SOX4.

Confidence score:

0.7372
