circRNA-disease information
Expression pattern:
DN
Associated gene: MMP2, MMP9, VEGF
Associated microRNA: miR-19a
Biological function: Tumor suppressive role in pancreatic adenocarcinoma cells by inhibiting proliferation, migration, and invasion.
Molecular mechanism: Circ-MYBL2 decreases miR-19a accumulation by increasing methylation of the miR-19a RNA gene/promoter region, thereby suppressing malignant phenotypes.
Biological pathway or process:

m6A modification (not specified); proliferation (inhibits); migration (inhibits); invasion (inhibits); mRNA stability (not specified); ceRNA regulation (other)

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation; Transfection; MSP (Methylation-Specific PCR); BrdU; Transwell Assay; Wound Healing Assay; Western Blot

Clinical significance:

-

Description:

Circ-MYBL2 is downregulated in pancreatic adenocarcinoma tissues and acts as a tumor suppressor in PA cells. Its overexpression reduces proliferation and motility by decreasing miR-19a levels, likely via increased methylation of the miR-19a RNA gene/promoter.

Confidence score:

0.6261
