circRNA-disease information
Expression pattern:
UP
Associated gene: IL-10
Associated microRNA: miR-125a-3p
Biological function: circMERTK enhances the immunosuppressive activity of TAM-like cells and promotes apoptosis of CD8+ T cells in the colorectal cancer microenvironment.
Molecular mechanism: circMERTK acts as a sponge for miR-125a-3p, thereby upregulating IL-10 expression and promoting TAM-like cell-mediated immunosuppressive activity.
Biological pathway or process:

apoptosis (promotes); immune regulation (promotes); ceRNA regulation (promotes)

Detected method:
Q
H
S
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; circRNA-seq; RT-qPCR; ISH (In Situ Hybridization); IF (Immunofluorescence); Clinical Sample Validation; RNA Pull-Down; Luciferase Reporter Assay; Transfection; Annexin V/PI Flow Cytometry; ELISA; Western Blot; Bioinformatics Analysis

Clinical significance:

circMERTK may serve as a potential therapeutic target for CRC.

Description:

circMERTK is up-regulated in TAM-like cells and CRC tissues, especially overlapping with CD68-positive macrophages. It promotes TAM-like cell immunosuppressive activity by sponging miR-125a-3p to increase IL-10, thereby enhancing CD8+ T-cell apoptosis, and may represent a potential therapeutic target in CRC.

Confidence score:

0.8331
