circRNA-disease information
Expression pattern:
UP
Associated gene: -
Associated microRNA: -
Biological function: circPVT1 is up-regulated in HNC cells and HNC cancer tissue, reduced after irradiation, and proposed as a potential biomarker to monitor radiotherapy effects in HNC patients.
Molecular mechanism: Predicted circRNA-miRNA interactions and radiation-induced changes in circPVT1 expression and cDNA pattern; the mechanistic role requires further study.
Biological pathway or process:

ceRNA regulation (other); radioresistance (other); other pathway/process (other)

Detected method:
Q
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RT-qPCR; Bioinformatics Analysis; Survival Analysis

Clinical significance:

circPVT1 may be a potential biomarker to monitor radiotherapy effects in HNC patients; high expression was non-significantly associated with poor overall survival.

Description:

hsa_circ_0001821/circPVT1, derived from the PVT1 locus, is significantly up-regulated in Detroit-562 HNC cells and HNC cancer tissue and is reduced after irradiation. The study predicts circPVT1-miRNA interactions and proposes circPVT1 as a potential biomarker for monitoring radiotherapy effects in HNC patients, although its association with poor overall survival was not statistically significant.

Confidence score:

0.4685
