circRNA-disease information
Expression pattern:
DN
Associated gene: ARNT, TACC3, VEGF, VEGFA, VEGFR2, HIF1a
Associated microRNA: -
Biological function: Inhibits tumor angiogenesis by suppressing endothelial cell proliferation, migration, and differentiation; suppresses xenograft tumor growth in vivo.
Molecular mechanism: circ-0000437 encodes peptide CORO1C-47aa; CORO1C-47aa binds ARNT (PAS-B domain) and competitively blocks ARNT-TACC3 interaction, suppressing VEGF transcription and secretion, leading to reduced angiogenesis.
Biological pathway or process:

angiogenesis (inhibits); proliferation (inhibits); migration (inhibits); other pathway/process (inhibits)

Description:

In endometrial cancer, circ-0000437 is down-regulated and encodes the peptide CORO1C-47aa. CORO1C-47aa binds ARNT (PAS-B domain), disrupts ARNT-TACC3 coactivation, suppresses VEGF/VEGFA signaling, and thereby inhibits tumor angiogenesis and reduces xenograft growth.

Confidence score:

0.8536
