Across TCGA pan-cancer cohorts, LIMS4 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of LIMS4’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where LIMS4 RNA is repressed in tumor relative to normal tissue. In most cancer types LIMS4 is over-expressed in tumor, although a few such as STAD show the opposite, repressed pattern.
STAD and KICH are the cancer types where LIMS4 tumor–normal differential expression is most reproducible.
