circRNA-disease information
Expression pattern:
UP
Associated gene: NSUN5
Associated microRNA: -
Biological function: circSOD2 was identified as an NSUN5-regulated m5C-modified circRNA elevated in ccRCC tumors and metastatic lesions; no direct functional phenotype was reported for circSOD2.
Molecular mechanism: NSUN5 positively regulates both m5C modification and expression of circSOD2; downstream functional mechanism was not further characterized.
Biological pathway or process:

other pathway/process (other)

Detected method:
Q
S
M
Validation methods:

RT-qPCR; RNA-seq; Microarray; MeRIP / MeRIP-seq; Bioinformatics Analysis

Clinical significance:

circSOD2 was elevated in ccRCC tumors and metastatic lesions, but the article did not report a circSOD2-specific clinical biomarker conclusion.

Description:

circSOD2 was identified as an up-regulated, NSUN5-regulated m5C-modified circRNA in ccRCC. The study did not further validate circSOD2-specific functional mechanisms beyond expression and m5C regulation.

Confidence score:

0.413
