CUL4B

Across TCGA pan-cancer cohorts, CUL4B mass-spec protein differs between tumor and matched normal tissue in 7 of 18 cancer types tested, making tumor–normal expression one of CUL4B’s most consistent transcriptional readouts.

The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where CUL4B mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types CUL4B is over-expressed in tumor, although a few such as PDAC show the opposite, repressed pattern.

CCRCC, LSCC, and LUAD are the cancer types where CUL4B tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in CUL4B mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
