| Abstract: | The aim of this study was to investigate the expression and clinical significance of NLRP3 inflammasome and downstream inflammatory genes in canine mammary tumors(CMTs). The mRNA expression levels of NLRP3, Caspase-1, IL-1 and IL-18 in 45 CMTs (15 benign tumors and 30 malignant tumors) and 16 tumor adjacent normal mammary gland tissues were detected by real-time quantitative polymer chain reaction. The relationship between NLRP3 and clinicopathological features (tumor size, tumor subtype, histological malignant grade and prognosis) was also analyzed. The results showed that the mRNA expression of NLRP3 and downstream inflammatory factors were up-regulated in tumor tissues compared with normal mammary tissues, and the relative mRNA expression of NLRP3 (P=0.006) and Caspase-1 (P=0.048) in MCMTs was significantly higher than that in BCMTs. Besides，the expression of NLRP3 mRNA in MCMTs was statistically different in tumor type (P=0.029) and malignant grade (P=0.049). This study suggests that up-regulation of NLRP3 expression may promote canine mammary tumorigenesis, and could be a diagnostic predictor for CMTs and its malignant features. |
