circRNA-disease information
Expression pattern:
UP
Associated gene: UBE2A, MDM2, p53, Bcl2, Bax
Associated microRNA: miR-527
Biological function: promotes proliferation, migration, and invasion; promotes tumorigenesis in vivo
Molecular mechanism: Acts as a sponge of miR-527 to regulate UBE2A, involving the MDM2/p53/Bcl2/Bax pathway and EMT-related markers.
Biological pathway or process:

ceRNA regulation (promotes); EMT (promotes); apoptosis (inhibits)

Detected method:
Q
S
Validation methods:

RNA-seq; RT-qPCR; RNase R Treatment; Sanger Sequencing; Nuclear-Cytoplasmic Fractionation; Luciferase Reporter Assay; RNA Pull-Down; Transfection; CCK8; EdU Staining; Colony Formation Assay; Wound Healing Assay; Transwell Assay; Western Blot; IHC (Immunohistochemistry); H&E Staining; In Vivo Animal Model; Clinical Sample Validation; Survival Analysis; Bioinformatics Analysis

Clinical significance:

High expression of hsa_circ_0001394 was related to poor survival and correlated with tumor differentiation, vascular invasion, and AFP levels; increased plasma expression correlated with clinicopathological features including elevated vascular invasion and an advanced TNM stage.

Description:

hsa_circ_0001394 (circTBC1D14) is up-regulated in HCC tissues/cells/plasma and mainly localized in the cytoplasm. It promotes HCC cell proliferation, migration, invasion and tumor growth by sponging miR-527, thereby relieving repression of UBE2A and affecting downstream MDM2/p53/Bcl2/Bax and EMT-related changes.

Confidence score:

0.8658
