Despite recent progress in the identification of genetic and molecular alternations in colorectal carcinoma, the precise molecular pathogenesis remains unclear. NALP1 (nucleotide-binding oligomerization domain-like receptor family, pyrin domain-containing 1) is a member of the nucleotide-binding oligomerization domain-like receptor family of proteins that are key organization proteins in the inflammasome. It is reported that NALP1 plays a central role in cell apoptosis, pyroptosis, inflammatory reactions and autoimmune diseases. DAC (5-aza-2-deoxycytidine) is an antitumor drug useful to lung cancer, myelodysplastic disorders, myelodysplasia and acute myeloid leukemia. In this study, we examined the expression of NALP1 in human normal and cancerous colon tissues using tissue microarray, western blot and quantitative real-time PCR and we measured the expression of NALP1 in three kinds of colon cancer cell lines and animal models before and after treatment with DAC. Furthermore, we examined the treatment effects of DAC on colon cancer in our animal model. Our data indicate that NALP1 is expressed low in human colorectal tumoral tissues relative to paratumoral tissues and was associated with the survival and tumor metastasis of patients. The expression of NALP1 increased after treatment with DAC both in vitro and in vivo. Furthermore, DAC suppressed the growth of colon cancer and increased lifespan in mouse model. Therefore, we conclude that NALP1 is expressed low in colon cancer and associated with the survival and tumor metastasis of patients, and treatment with DAC can restore NALP1 levels to suppress the growth of colon cancer.
