Low expression of XIAP‐associated factor 1 in human colorectal cancers

Abstract

The present results suggest that the low expression of XAF1 in tumor tissue coincides with a similar level in the peripheral circulation, which contributes at least part to the malignant behavior of CRC. Integrating the XAF1 relative expression value with the other three traditional tumor biomarkers created a four-parameter assay that significantly improved the rate of diagnosis of CRC.
