Abstract
Loach (Misgurnus anguillicaudatus) is a common freshwater commercial fish species in China. The meat of this fish is a good source of protein and other nutrients that are needed for human health. Aquaculture challenges such as diseases and pest susceptibility, excessive density, and nutritional deficiency result in low production of loach rather than increased demand. Due to a lack of knowledge about the immune system of loaches, we carried out this study to better understand its antibacterial molecular mechanism. Here, we performed RNA sequencing from liver tissue obtained from soya bean-fermented fed loach after subjecting it to the LPS challenge. The results revealed a total of 18,399 differentially expressed genes (DEGs) in the LPS-treated and control groups. There were 7482 DEGs that were upregulated and 10,917 DEGs were downregulated. The enrichment analysis of DEGs revealed that the majority of DEGs were found to be abundant in the pathways of DNA replication, spliceosome, nucleotide exception repair, cell cycle, and Herpes simplex virus 1 infection. Furthermore, qRT-PCR analysis of 21 selected DEGs demonstrated that the transcriptomic data is extremely reliable. Overall, this study provides insight into the molecular features and control mechanisms of genes that affect loach growth. The availability of this information will also contribute to the enhancement of the breeding and protection of loach resources.
