摘要:

初步研究RNA干扰PhCatC1/2基因对波纹龙虾(Panulirus homarus)相关免疫基因表达的影响,采用qPCR技术检测PhCatC1/2、PhTlr13、PhLysPhβ-G基因的表达,并观察肝胰腺组织的变化情况。结果表明:注射PhCatC1-dsRNA后,PhCatC2表达量比对照组显著下降(P<0.05),与对照组相比PhTlr13基因表达量在前期呈现显著升高,后下降的趋势,PhLysPhβ-G基因的表达量均随dsRNA干扰时效的增加而增加;沉默PhCatC2基因后PhTlr13和Phβ-G基因的表达量随dsRNA干扰时效的增加而增加,PhCatC1基因表达量呈现下上调交替的趋势,PhLys基因表达量表现出先下调后上调的趋势。通过PhCatC1/2基因沉默后的分析初步推测,波纹龙虾可能通过促进Toll样受体和溶酶体通路来参与免疫应答,得出PhCatC1/2基因具有免疫功能。

Abstract:

Preliminary study of the effect of RNA interference with the PhCatC1/2 gene on the expression of immune genes associated with Panulirus homarus,the expression of PhCatC1/2, PhTlr13, PhLys and Phβ-G genes were detected by qPCR and changes in hepatopancreatic tissue were observed. The results showed that the expression of PhCatC2 was significantly different from the control group after PhCatC1-dsRNA injection (P<0.05), the PhTlr13 gene expression showed a significant increase in the first period and then a decrease compared with the control group,expression of both PhLys and Phβ-G genes increased with increasing duration of dsRNA interference. Expression of PhTlr13 and Phβ-G genes increased with increasing duration of dsRNA interference after silencing of the PhCatC2 gene, PhCatC1 gene expression showed an alternating trend of down- and up-regulation, PhLys gene expression showed a trend of down-regulation followed by up-regulation. Preliminary speculation from analysis of the PhCatC1/2 gene after silencing that the lobster Panulirus homarus may be involved in the immune response by promoting Toll-like receptor and lysosomal pathways and concluding that the PhCatC1/2 gene has an immune function.
