Tumor necrosis factor (TNF)-alpha-induced protein 8 (TNFAIP8 or TIPE) is a recently identified protein considered to be associated with carcinogenesis. To investigate its expression pattern in pancreatic cancer patients and to analyse its correlation with clinicopathological significance and the expression levels of epithelial growth factor receptor (EGFR), immunohistochemistry was performed to detect the TNFAIP8 and EGFR proteins in pancreatic cancers, pancreatitis tissues, and healthy controls. The results showed stronger staining of TNFAIP8 protein in pancreatic cancer tissues compared with normal pancreas tissue. Furthermore, in 56 patients with pancreatic cancer, the expression levels of TNFAIP8 in patients with low tumor stage was higher than that with high tumor stage, and correlated with tumor staging and lymph node metastasis (P<0.05). Furthermore, TNFAIP8 expression positively correlated with EGFR levels (r=0.671135, P<0.05). These results indicate that TNFAIP8 may play important roles in the progression of pancreatic cancer.

Viral diseases cause enormous economic losses to the olive flounder (Paralichthys olivaceus) aquaculture industry in Korea. This study aimed to identify immune-related genes expressed in the kidney of olive flounder injected with Polyinosinic-polycytidylic acid (Poly (I:C)). Thirty fish were divided into two groups by intraperitoneal injection of 100µl of diethylpyrocarbonate-treated water or poly I:C per fish. Kidney tissues at day 3 and 30 after the injection were used for RNA-seq analysis to identify differentially expressed genes (DEGs). Poly I:C group upregulated il8, cfh, tnfaip2b, c3b.2, ly6d and cd38 genes at 3 days post-injection. Additionally, cd22, ccl34a.3, c9, cxcl19, ccl27a, ccl7, and cfh genes were upregulated at 30 days post-injection. Differential expression gene analysis showed that poly I:C has both short and long-term immune effects in olive flounder. This study provides a theoretical basis for understanding the molecular mechanism of the short and long-term immune effects of poly I:C.
