Innate immunity serves as the rapid and frst-line defense against invading pathogens,and this process can be regulated at various levels,including epigenetic *** bromodomain and extraterminal domain(BET)family of proteins consists of four conserved mammalian members(BRD2,BRD3,BRD4,and BRDT)that regulate the expression of many immunity-associated genes and *** particular,in response to infection and sterile inflammation,abnormally expressed or dysfunctional BETs are involved in the activation of pattern recognition receptor(e.g,TLR,NLR,and CGAS)pathways,thereby linking chromatin machinery to innate immunity under disease or pathological ***,the BET family controls the transcription of a wide range of proinflammatory and immunoregulatory genes by recognizing acetylated histones(mainly H3 and H4)and recruiting transcription factors(e.g.,RELA)and transcription elongation complex(e.g.P-TEFb)to the chromatin,thereby promoting the phosphorylation of RNA polymerase II and subsequent transcription initiation and *** review covers the accumulating data about the roles of the BET family in innate immunity,and discusses the attractive prospect of manipulating the BET family as a new treatment for disease.

IM To study VEGF mRNA expression in gastric carcinoma and to clarify the association of its expression with the clinicopathologic features of the disease.METHODS In situ hybridization (ISH) and histochemistry were used to examine and analyze the expression of VEGF mRNA and antigen, and microvessel count (MVC) in 28 cases of gastric carcinomatous tissue in combination with clinical materials.RESULTS Ninteen of 28 gastric carcinomas were positive for VEGF mRNA. VEGF mRNA was mainly expressed in malignant cells and not in normal epithelium of gastric mucosa. Its expression was further increased in tumor cells adjacent to tumor necrosis zones, where stromal cells expressed VEGF mRNA occasionally. There was a close correlation between MVC and VEGF mRNA positivity (P<0005). High VEGF mRNA levels were significantly associated with serosal invasion, lymph node metastasis and TNM staging (P<005, respectively).CONCLUSION VEGF mRNA expression is associated with tumor invasion and metastasis by stimulating angiogenesis in gastric ***; endothelial growth factor.
