circRNA-disease information
Expression pattern:
UP
Associated gene: IRGQ
Associated microRNA: miR-1294
Biological function: Circ_0000854 promoted HCC cell proliferation, cell cycle progression, migration, invasion, tumor growth and metastasis; knockdown of circ_0000854 suppressed these malignant behaviors.
Molecular mechanism: Circ_0000854 functions as a miR-1294 sponge to upregulate IRGQ expression, thereby accelerating HCC progression through the circ_0000854/miR-1294/IRGQ ceRNA axis.
Biological pathway or process:

proliferation (promotes); cell cycle (promotes); migration (promotes); invasion (promotes); metastasis (promotes); EMT (promotes); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

RT-qPCR; Bioinformatics Analysis; Clinical Sample Validation; Survival Analysis; Nuclear-Cytoplasmic Fractionation; Transfection; MTT; EdU Staining; Cell Cycle Assay; Wound Healing Assay; Transwell Assay; RNA Pull-Down; Luciferase Reporter Assay; Western Blot; In Vivo Animal Model; H&E Staining; IHC (Immunohistochemistry)

Clinical significance:

High circ_0000854 expression was associated with significantly lower survival rate in HCC patients.

Description:

This study identified hsa_circ_0000854/circZCCHC2 as an up-regulated oncogenic circRNA in hepatocellular carcinoma. Circ_0000854 mainly localizes in the cytoplasm and promotes proliferation, cell cycle progression, migration, invasion, EMT-related protein changes, tumor growth and metastasis by sponging miR-1294 to increase IRGQ expression. High circ_0000854 expression was associated with poorer survival in HCC patients.

Confidence score:

0.7981
