Background: The RGS family, comprising 22 homologues of proteins, plays a role in cellular proliferation, differentiation, membrane trafficking, and embryonic development through the involvement of the mitogen-activated protein kinase signaling pathway. Methods: In order to demonstrate the importance of RGS16 expression for the prediction of prognosis of colorectal cancer (CRC), we analyzed RGS16 gene expression in 22 human gastrointestinal cell lines and 124 paired cases of CRC and noncancerous regions. Results: RGS16 was expressed in 17 human gastrointestinal cancer cell lines examined in this study. RGS16 expression was higher in colorectal cancer tissue than in corresponding normal tissue (P < 0.001) in messenger RNA (mRNA) and protein levels. Patients in the RGS16 high-expression group showed a poorer overall survival rate than those in the low-expression group (P < 0.001), indicating that high RGS16 expression was an independent prognostic factor. Conclusion: The present study suggests that RGS16 is useful as a predictive marker for patient prognosis of CRC.
