ABSTRACT
Background and Aim: Despite the economic importance of buffalo as a main source of milk and meat, only little attention has been directed to its immune and reproductive performance. The early diagnosis of subclinical endometritis may reduce the economic loss of buffalo’s production. The difference in expression profiles of immunity-related genes has an important role in the early detection of subclinical endometritis. This study aimed to assess the expression of five immunity-related genes: TGFBR1, PTGER2, PTGER4, HP and CXCL5 in endometritis-infected buffaloes. Materials and Methods: Total RNA was extracted from 120 buffalo uterine samples; 60 infected with endometritis and 60 healthy ones. Qt-PCR was performed on cDNA synthesized from extracted RNA using Sybr green and GAPDH as a house-keeping gene. Results: The results showed the up-regulation of two tested genes; TGFBR1 and CXCL5 in endometritis-infected buffalo compared to healthy animals by 7.9 and 4.3 folds, respectively at a significance level of p<0.05. The other three tested genes; PTGER2, PTGER4 and HP were down-regulated in buffalo during endometritis infection at different levels; PTGER2 and HP (0.6 folds, p<0.05) and PTGER4 (0.4 fold, p= 0.2). Conclusions: It is to be concluded that the assessment of expression of inflammation-related immunity genes may have an effective role on the detection of endometritis infection in buffalo during its early stages and this early diagnosis can reduce the economic loss of buffalo production and reproduction.
ABSTRACT
Objective:To systematically review the relationship between PTGER 4 genetic polymorphisms and the risk of inflam-matory bowel disease (IBD).Methods:All eligible case-control studies which published up to February 29,2016 were searched by PubMed,Embase,Web of Science.The studies in accordance with high quality were included in this study .We synthesized pooled odds ratio ( OR) and its 95%confidence interval ( CI) using STATA12.0.The sensitivity analysis was used to determine the stability of re-sults in meta-analysis.The Egger′s analysis was performed to evaluate the publication bias .Results:Twenty original publications invol-ving 44 case-control studies were included in this study ,in which 25179 patients with Crohn′s disease (CD),5261 patients with ulcer-ative colitis ( UC) and 44652 control subjects were detected .The allelic frequency ,additive model ,dominant model and recessive mod-el were used to analyze the association of rs 4613763 T/C polymorphism and CD ,and the pooled OR and 95%CI were as followings:1.24 (1.06-1.45),1.32 (1.06-1.64),1.25 (1.06-1.48),1.28 (1.03-1.59).For rs17234657T/G polymorphism and CD,the pooled OR (95%CI) of four genetic models were 1.35 (1.28-1.47),2.12 (1.70-2.63),1.46 (1.36-1.57) and 1.90 (1.54-2.35),re-spectively.For rs4495224A/C polymorphism and CD,the pooled OR(95%CI) were 1.05 (0.79-1.41),1.08 (0.62-1.88),1.12 (0.75-1.65) and 1.00 (0.67-1.49).And the pooled OR (95%CI) were 0.77 (0.67-0.88),0.59 (0.51-0.69),0.73 (0.61-0.87),0.68 (0.59-0.79) for rs9292777G/T polymorphism and CD.For rs1373692T/G polymorphism and CD,the pooled OR (95%CI) were 1.23 (0.96-1.57),1.39 (0.74-2.59),1.26 (0.74-2.13),1.31 (1.00-1.72).The pooled OR (95%CI) of allelic fre-quency , additive model , dominant model and recessive model for the association of rs 4613763 T/C polymorphism with UC were 1.30 (1.17-1.44 ), 1.73 ( 1.16-2.59 ), 1.32 ( 1.17-1.48 ), 1.64 ( 1.10-2.45 ), respectively.Conclusion: Polymorphisms of rs17234657T/G,rs4613763T/C and rs9292777G/T are associated with CD.Polymorphism of rs4613763T/C is associated with UC sus-ceptibility.
