Across TCGA pan-cancer cohorts, GPR158-AS1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of GPR158-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where GPR158-AS1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types GPR158-AS1 is over-expressed in tumor.
UCEC, BRCA, and KIRC are the cancer types where GPR158-AS1 tumor–normal differential expression is most reproducible.
