Across TCGA pan-cancer cohorts, POU3F1 RNA differs between tumor and matched normal tissue in 10 of 18 cancer types tested, making tumor–normal expression one of POU3F1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where POU3F1 RNA is repressed in tumor relative to normal tissue. In most cancer types POU3F1 is over-expressed in tumor, although a few such as KICH and KIRP show the opposite, repressed pattern.
KICH, HNSC, and KIRC are the cancer types where POU3F1 tumor–normal differential expression is most reproducible.
RNA tumor vs normal associations by lineage
Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in POU3F1 RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
