circRNA-disease information
Expression pattern:
UP
Associated gene: SRSF10, Ago2, MMP2, VEGFA
Associated microRNA: miR-526b-3p
Biological function: promotes angiogenesis (cell viability, migration and tube formation) of glioma-associated endothelial cells
Molecular mechanism: SRSF10 promotes circ-ATXN1 biogenesis; circ-ATXN1 acts as a ceRNA sponge binding miR-526b-3p in Ago2/RISC to relieve miR-526b-3p-mediated repression of MMP2 and VEGFA
Biological pathway or process:

angiogenesis (promotes); proliferation (promotes); migration (promotes); invasion (other); ceRNA regulation (promotes)

Detected method:
Q
M
Validation methods:

RT-qPCR; Microarray; RNase R Treatment; Sanger Sequencing; Back-Splice Junction PCR / divergent primers PCR; FISH / smFISH; RIP (RNA Immunoprecipitation); Luciferase Reporter Assay; Transfection; CCK8; Transwell Assay; Tube Formation Assay; Western Blot; In Vivo Animal Model

Clinical significance:

-

Description:

circ-ATXN1 is up-regulated in glioma-associated endothelial cells and promotes angiogenesis-related behaviors (viability, migration, tube formation). Mechanistically, SRSF10 promotes circ-ATXN1 biogenesis, and circ-ATXN1 sponges miR-526b-3p in Ago2/RISC to increase MMP2/VEGFA and enhance angiogenesis.

Confidence score:

0.7763

Title:
