Recently, the gene PTPRJ (protein tyrosine phosphatase receptor type J) was identified as the candidate gene for the mouse colon cancer susceptibility locus Scc1.
The protein tyrosine phosphatase receptor type J (PTPRJ) has been recently identified as being the protein encoded by the Scc1 mouse gene (susceptibility to colon cancer-1).
Nutrients, which are considered to be chemoprotective with respect to colon cancer development, including butyrate, green tea and apple polyphenols, had the capacity to elevate transcription of endogenous DEP-1 mRNA and expression of DEP-1 protein.
Compared with the major homozygotes at the Arg326Gln SNP in PTPRJ, a likely homologue of the mouse SCC1 (susceptible to colon cancer), Arg/Gln or Gln/Gln genotypes exhibited an increased colorectal cancer risk with adjusted odds ratios (aOR) of 1.71 (P = 0.021) and 3.74 (P = 4.14 x 10(-4)), respectively.
