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.
