circRNA-disease information
Expression pattern:
UN
Associated gene: METTL3
Associated microRNA: miR-let-7b
Biological function: Promotes proliferation and invasion and inhibits apoptosis in HCT116 colorectal cancer cells.
Molecular mechanism: hsa_circ_0000523 suppresses miR-let-7b, thereby upregulating METTL3 (ceRNA-like regulation).
Biological pathway or process:

proliferation (promotes); apoptosis (inhibits); invasion (promotes); ceRNA regulation (other)

Detected method:
Q
Validation methods:

RT-qPCR; Luciferase Reporter Assay; Transfection; CCK8; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot

Clinical significance:

circRNAs and METTL3 may be applied for highly sensitive diagnosis of CRC and for predicting prognosis in patients who have undergone therapy.

Description:

In HCT116 colorectal cancer cells, hsa_circ_0000523 promotes proliferation and invasion and inhibits apoptosis. Mechanistically, it forms a hsa_circ_0000523/miR-let-7b/METTL3 regulatory axis in which circ_0000523 suppresses miR-let-7b and thereby increases METTL3 expression.

Confidence score:

0.528
