circRNA-disease information
Expression pattern:
UP
Associated gene: YAP1, MST1, LAST1, YAP, TAZ
Associated microRNA: -
Biological function: promotes proliferation; promotes migration; promotes invasion; promotes tumor growth; promotes metastasis
Molecular mechanism: circPPP1R12A carries an ORF and encodes a 73-aa peptide (circPPP1R12A-73aa) that activates Hippo-YAP signaling to promote colon cancer growth and metastasis.
Biological pathway or process:

Hippo/YAP (promotes); proliferation (promotes); migration (promotes); invasion (promotes); metastasis (promotes)

Detected method:
Q
H
M
Validation methods:

Microarray; RT-qPCR; RNase R Treatment; Back-Splice Junction PCR / divergent primers PCR; FISH / smFISH; Nuclear-Cytoplasmic Fractionation; ISH (In Situ Hybridization); Clinical Sample Validation; Transfection; CCK8; Colony Formation Assay; Cell Cycle Assay; Transwell Assay; Wound Healing Assay; In Vivo Animal Model; RNA-seq; Western Blot; Survival Analysis; Cohort Study

Clinical significance:

Patients with higher expression of circPPP1R12A had a shorter overall survival; circPPP1R12A ISH score 3-4 was an independent poor prognostic factor.

Description:

circPPP1R12A (hsa_circ_0000423), derived from PPP1R12A, is up-regulated in colon cancer tissues/cell lines and mainly localized in the cytoplasm. It contains an ORF that encodes a 73-aa peptide (circPPP1R12A-73aa), which promotes colon cancer proliferation and metastasis by activating Hippo/YAP signaling, and higher circPPP1R12A levels are associated with worse overall survival.

Confidence score:

0.7987
