吸血和约氏疟原虫感染对大劣按蚊血细胞中rpS7转录的影响

Effect of blood-feeding and plasmodium yoelii infection on the transcript abundance of ribosomal protein S7 from Anopheles dirus hemocyte

目的 观察血餐和约氏疟原虫感染对大劣按蚊血细胞中核糖体蛋白S7(Ribosomalprotein ,rpS7)转录的影响。方法 同批 3～ 5d龄大劣按蚊分为正常组 (N)、吸正常血组 (B)和感染约氏疟原虫组 (I) ,分别在血餐后 1、2、3、7d ,离心法同时收集 3组各 5 0只雌大劣按蚊血细胞总RNA ,所有样品进行RT PCR后 ,各吸取 10ulPCR产物进行琼脂糖凝胶电泳 ,凝胶图像分析系统扫描并读取数据 ,并对所得数据进行统计学分析。结果 3组大劣按蚊血细胞rpS7mRNA的RT PCR扩增产物量无显著差异 (P >0 0 5 )。结论 类似于人类和小鼠 β actin ,以及冈比亚按蚊rpS7。

Objective To observe the effect of blood feeding and plasmodium yoelii infection on the transcript abundance of ribosomal protein S7 from Anopheles dirus hemocyte Methods Anopheles dirus of 3～5 days old were divided into normal group (N), blood feeding group(B) and Plasmodium yoelii infection group(I) Hemocytes of 50 Anopheles dirus from each group were collected by centrifuge method on days 1, 2, 3, 4, 7 and 11 after blood feeding, respectively Then, all hemocyte samples were used for total RNA isolation and analyzed by RT PCR Finally, the same volume(10 μl) of all the PCR products from each group was used for agarose gel electrophoresis and the data obtained were analyzed statistically Results There was no significant difference in ribosomal protein S7 signal between the three groups Conclusion Similar to Anopheles gambiae and human rpS7, Anopheles dirus rpS7 might be also used as an internal control for the studies of the role of Anopheles dirus related immune factors in attacking Plasmodium infection
