circRNA-disease information
Expression pattern:
DN
Associated gene: -
Associated microRNA: precursor miR-92b
Biological function: Circ-MYBL2 suppresses gastric cancer cell proliferation and tumor growth, and suppresses the proliferative effect of mature miR-92b.
Molecular mechanism: Circ-MYBL2 binds and sponges precursor miR-92b in the nucleus, increases precursor miR-92b accumulation, decreases mature miR-92b levels, and thereby suppresses miR-92b maturation.
Biological pathway or process:

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

Detected method:
Q
S
Validation methods:

RT-qPCR; Clinical Sample Validation; Nuclear-Cytoplasmic Fractionation; RNA Pull-Down; Transfection; BrdU; Northern Blot; In Vivo Animal Model; Bioinformatics Analysis

Clinical significance:

CircRNA circ-MYBL2 was closely associated with tumor size, but not other clinical factors.

Description:

Circ-MYBL2 is down-regulated in gastric cancer tissues and cell lines. It acts as a tumor-suppressive circRNA by binding precursor miR-92b, suppressing miR-92b maturation, and inhibiting gastric cancer cell proliferation and xenograft tumor growth.

Confidence score:

0.6824

Other information
Title:

CircRNA circ-MYBL2 absorbs precursor miR-92b in the nucleus to suppress its role in enhancing gastric cancer cell proliferation.
