Tibial dyschondroplasia (TD) is a skeletal deformity disease in broilers that occurs when vascularization in the growth plate (GP) is below normal. Although, blood vessels have been reported to contribute significantly in bone formation. Therefore, in the current study, we have examined the mRNA expression of angiogenesis-related genes in erythrocytes of thiram induced TD chickens by qRT-PCR and performed histopathological analysis to determine regulatory effect of recombinant Glutathione-S-Transferase A3 (rGSTA3) protein in response to the destructive effect of thiram following the injection of rGSTA3 protein. Histopathology results suggested that, blood vessels of GPs were damaged in thiram induced TD chicken group (D), it also affected the area and density of blood vessels. In the 20 and 50 μg·kg-1 of rGSTA3 protein-administered groups, E and F vessels appeared to be normal and improved on day 6 and 15. Furthermore, qRT-PCR results showed that rGSTA3 protein significantly (P < .05) up-regulated the expression of the most important angiogenesis-related integrin family genes ITGA2, ITGA5, ITGB2, ITGB3, ITGAV. The expression level of other genes including TBXA2R, FYN, IQGAP2, IL1R1, GIT1, RAP1B, RPL17, RAC2, MAML3, PTPN11, VAV1, PTCH1, NCOR2, CLU and ITGB3 up-regulated on dosage of rGSTA3 protein. In conclusion, angiogenesis is destroyed in thiram induced TD broilers, and rGSTA3 protein injection improved the vascularization of GPs by upregulating the angiogenesis related genes most importantly integrin family genes ITGAV, ITGA2, ITGB2, ITGB3, ITGA5.

重组谷胱甘肽-S-转移酶A3蛋白调节硫胺素诱发的胫骨病变中红细胞的血管生成相关基因。

胫骨软骨发育不良(TD)是肉鸡的骨骼畸形疾病,当生长板(GP)中的血管生成低于正常水平时会发生。虽然,据报道血管在骨形成中起重要作用。因此,在本研究中,我们通过qRT-PCR检测了在硫胺素诱导的TD鸡的红细胞中血管生成相关基因的mRNA表达,并进行了组织病理学分析,以确定重组谷胱甘肽-S-转移酶A3(rGSTA3)蛋白在小鼠中的调节作用。注射rGSTA3蛋白后,对硫胺素的破坏作用有反应。组织病理学结果表明,在硫柳胺诱导的TD鸡组(D)中GP的血管受到损害,这也影响了血管的面积和密度。在20和50μg·kg-1的rGSTA3蛋白给药组中,E和F血管似乎正常并在第6和15天有所改善。此外,qRT-PCR结果显示rGSTA3蛋白显着(P <.05)上调了最重要的血管生成相关整合素家族基因ITGA2的表达, ITGA5,ITGB2,ITGB3,ITGAV。其他基因的表达水平包括TBXA2R,FYN,IQGAP2,IL1R1,GIT1,RAP1B,RPL17,RAC2,MAML3,PTPN11,VAV1,PTCH1,NCOR2,CLU和ITGB3随rGSTA3蛋白剂量上调。总之,在硫胺素诱导的TD肉鸡中,血管生成被破坏,而rGSTA3蛋白注射通过上调与血管生成相关的基因,最重要的是整联蛋白家族基因ITGAV,ITGA2,ITGB2,ITGB3,ITGA5,改善了GP的血管生成。qRT-PCR结果表明,rGSTA3蛋白显着(P <.05)上调了最重要的血管生成相关整合素家族基因ITGA2,ITGA5,ITGB2,ITGB3,ITGAV的表达。其他基因的表达水平包括TBXA2R,FYN,IQGAP2,IL1R1,GIT1,RAP1B,RPL17,RAC2,MAML3,PTPN11,VAV1,PTCH1,NCOR2,CLU和ITGB3随rGSTA3蛋白剂量上调。总之,在硫胺素诱导的TD肉鸡中,血管生成被破坏,而rGSTA3蛋白注射通过上调与血管生成相关的基因(最重要的是整联蛋白家族基因ITGAV,ITGA2,ITGB2,ITGB3,ITGA5)来改善GP的血管形成。qRT-PCR结果表明,rGSTA3蛋白显着(P <.05)上调了最重要的血管生成相关整合素家族基因ITGA2,ITGA5,ITGB2,ITGB3,ITGAV的表达。其他基因的表达水平包括TBXA2R,FYN,IQGAP2,IL1R1,GIT1,RAP1B,RPL17,RAC2,MAML3,PTPN11,VAV1,PTCH1,NCOR2,CLU和ITGB3随rGSTA3蛋白剂量上调。总之,在硫胺素诱导的TD肉鸡中,血管生成被破坏,而rGSTA3蛋白注射通过上调与血管生成相关的基因(最重要的是整联蛋白家族基因ITGAV,ITGA2,ITGB2,ITGB3,ITGA5)来改善GP的血管形成。GIT1,RAP1B,RPL17,RAC2,MAML3,PTPN11,VAV1,PTCH1,NCOR2,CLU和ITGB3在rGSTA3蛋白的剂量上调。总之,在硫胺素诱导的TD肉鸡中,血管生成被破坏,而rGSTA3蛋白注射通过上调与血管生成相关的基因(最重要的是整联蛋白家族基因ITGAV,ITGA2,ITGB2,ITGB3,ITGA5)来改善GP的血管形成。GIT1,RAP1B,RPL17,RAC2,MAML3,PTPN11,VAV1,PTCH1,NCOR2,CLU和ITGB3在rGSTA3蛋白的剂量上调。总之,在硫胺素诱导的TD肉鸡中,血管生成被破坏,而rGSTA3蛋白注射通过上调与血管生成相关的基因(最重要的是整联蛋白家族基因ITGAV,ITGA2,ITGB2,ITGB3,ITGA5)来改善GP的血管形成。
