In a study of fecal matter from 44 CRC patients, 15 controls, and 11 colonic cell lines, a quantitative real-time reverse transcription PCR detected 7/24 patients with late-stage CRC expressed 2-times more RPL19 in colonic tumour tissue than normal, and the mean fecal RPL19 mRNA levels of late-staged patients were also higher than the controls. This evidence concerns the gene RPL19 and colonic neoplasm.
