Validation methods:

divergent primers PCR; Sanger Sequencing; RNase R Treatment; RT-qPCR; Nuclear-Cytoplasmic Fractionation; ISH (In Situ Hybridization); Clinical Sample Validation; In Vivo Animal Model; Bioinformatics Analysis; RNA-seq

Clinical significance:

RISH signals stronger in castration-resistant PDXs; part of circAR set proposed as circulating biomarkers.

Description:

circAR-E3 is an AR-derived circRNA significantly upregulated in castration-resistant PDX tumors and predominantly localized in the cytoplasm, validated by fractionation and BaseScope RISH. It is discussed as part of a circAR biomarker set for mCRPC, and it has hypothesized peptide-coding potential based on an open reading frame.

Confidence score:

0.7008
