circRNA-disease information
Expression pattern:
UP
Associated gene: CNOT7, CCR4-NOT transcription complex and subunit 7, beta-catenin, cyclin D1, c-myc, Wnt signaling
Associated microRNA: miR-578
Biological function: Promotes osteosarcoma cell proliferation, migration, and invasion; inhibits apoptosis; contributes to osteosarcoma progression.
Molecular mechanism: hsa_circ_001350 functions as a miR-578 sponge to increase CNOT7 protein levels and activate Wnt signaling, including beta-catenin, cyclin D1, and c-myc expression.
Biological pathway or process:

Wnt/beta-catenin (promotes); proliferation (promotes); migration (promotes); invasion (promotes); apoptosis (inhibits); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

RNase R Treatment; RT-qPCR; Nuclear-Cytoplasmic Fractionation; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; EdU Staining; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot; Bioinformatics Analysis

Clinical significance:

hsa_circ_001350, miR-578, and CNOT7 may be potential targets for the treatment of OS.

Description:

hsa_circ_001350 is up-regulated in osteosarcoma samples and cell lines and acts as an oncogenic circRNA. It promotes OS cell proliferation, migration, and invasion while suppressing apoptosis by sponging miR-578, thereby increasing CNOT7 protein levels and activating Wnt/beta-catenin-related signaling. The study suggests that hsa_circ_001350 and its miR-578/CNOT7/Wnt axis may be therapeutic targets in osteosarcoma.

Confidence score:

0.7204
