circRNA-disease information
Expression pattern:
UP
Associated gene: SEPT2, ERK1/2, AGO2
Associated microRNA: miR-497
Biological function: Promotes PCa cell proliferation and invasion and reduces cell death; EV-derived circ_SLC19A1 can be transferred into recipient PCa cells and regulate their biological functions.
Molecular mechanism: EV-derived circ_SLC19A1 acts as a miR-497 sponge to relieve miR-497-mediated suppression of SEPT2, thereby activating the downstream ERK1/2 pathway.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

RT-qPCR; Nuclear-Cytoplasmic Fractionation; RIP (RNA Immunoprecipitation); RNA Pull-Down; Luciferase Reporter Assay; Transfection; BrdU; Annexin V/PI Flow Cytometry; Transwell Assay; Western Blot; Bioinformatics Analysis

Clinical significance:

EV-derived circ_SLC19A1 may be an important target for PCa prevention and treatment.

Description:

circ_SLC19A1 is up-regulated in prostate cancer cells and their extracellular vesicles. EV-derived circ_SLC19A1 promotes PCa cell proliferation and invasion and suppresses cell death by sponging miR-497, increasing SEPT2 expression, and activating ERK1/2 signaling. The study suggests that EV-derived circ_SLC19A1 may be a therapeutic target for PCa prevention and treatment.

Confidence score:

0.6853
