Across TCGA pan-cancer cohorts, HSPE1P22 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of HSPE1P22’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where HSPE1P22 RNA is repressed in tumor relative to normal tissue. In most cancer types HSPE1P22 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
THCA are the cancer types where HSPE1P22 tumor–normal differential expression is most reproducible.
