Biological function: CircRSF1 may serve as a diagnostic biomarker for pSS and may regulate immune pathways through miRNA sponge activity, predicted miRNA-mRNA networks, protein binding, and m6A-related mechanisms.
Molecular mechanism: Predicted ceRNA/miRNA sponge mechanism involving CircRSF1-miRNA-mRNA regulation; predicted direct binding to RNA-binding proteins/proteins; predicted m6A modification sites.
Biological pathway or process:

ceRNA regulation (other); immune regulation (other); MAPK (other); p53 signaling (other); PI3K/AKT (other); AMPK (other); apoptosis (other); autophagy (other); m6A modification (other); inflammation (other)

Validation methods:

RT-qPCR; RNA-seq; RNase R Treatment; Sanger Sequencing; FISH / smFISH; Clinical Sample Validation; ROC Analysis; Bioinformatics Analysis; Back-Splice Junction PCR / divergent primers PCR

Clinical significance:

CircRSF1 may serve as a novel potential diagnostic biomarker for pSS and showed diagnostic specificity for pSS compared with SLE and RA.

Description:

CircRSF1 is a human circRNA derived from RSF1 that is significantly down-regulated in PBMCs and LSGs from pSS patients. The study supports its potential as a pSS-specific diagnostic biomarker and predicts that it may function through cytoplasmic miRNA sponge activity, CircRSF1-miRNA-mRNA regulation, protein/RBP interactions, and m6A-related mechanisms affecting immune and inflammatory pathways.
