circRNA-disease information
Expression pattern:
UP
Associated gene: EZH2, SUZ12
Associated microRNA: -
Biological function: In proliferative cells represses p15 and p21; in RAF1-induced senescence promotes transcriptional induction of INK4 genes and supports senescence-associated gene program.
Molecular mechanism: Interacts with PRC2 components (EZH2, SUZ12); modulates EZH2 recruitment and H3K27ac/H3K27me3 at INK4 locus to affect transcription.
Biological pathway or process:

cell cycle (other); proliferation (other); other pathway/process (other)

Detected method:
Q
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; RT-qPCR; Transfection; RNA-seq; Bioinformatics Analysis; RNA Pull-Down; Western Blot; ChIP / ChIP-seq

Clinical significance:

-

Description:

circANRIL e16-e5 is up-regulated in RAF1 oncogene-induced senescence and helps drive transcriptional activation of INK4 genes. Mechanistically, RNAs containing the e16-e5 back-spliced junction bind PRC2 components (EZH2/SUZ12) and influence EZH2 recruitment and H3K27 acetylation/methylation at the INK4 locus.

Confidence score:

0.7549
