Kidney transcriptome analysis of tiger puffer (Takifugu rubripes) uncovers key pathways and genes in response to low-temperature stress

Aquaculture Reports, Journal Year: 2022, Volume and Issue: 26, P. 101287 - 101287

The tiger puffer (Takifugu rubripes) is an important economic fish species in northern China; however, cold stress during overwintering can have serious adverse effects on its aquaculture. Understanding the mechanisms of resistance puffers will thus provide critical information regarding process. Here, we compared kidney transcriptomes at 5 °C and 23 to identify key pathways genes involved response low temperature stress. We identified a total 1679 differentially expressed (DEGs), including 635 up-regulated 1044 down-regulated with group. Kyoto Encyclopedia Genes Genomes enrichment analysis indicated five significantly enriched pathways, four which were related metabolism. Transcriptome data quantitative polymerase chain reaction verification showed that most DEGs down-regulated, ratio 26:6, among three involving amino acid lipid Further arginine proline pathway was primary signaling pathway, two metabolic for (including nitric oxide synthase arginase) likely be factors affecting puffers. Diet supplementation may improve tolerance These results provided new insights into impact aquaculture environment from perspective nutrition.

Multi-tissue metabolomic profiling reveals the crucial metabolites and pathways associated with scallop growth

BMC Genomics, Journal Year: 2024, Volume and Issue: 25(1)

Published: Nov. 15, 2024

Bivalves represent a vital economic resource in aquaculture for their high productivity and extensive market demand. Growth is one of the most important desired traits bivalves, regulated by multiple levels, notably intricate metabolic processes. However, understanding profiles that influence bivalve growth limited, particularly from multi-tissue perspective. In this study, tissues Chlamys farreri with different performance were systematically investigated ultraperformance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Through comparing variation between fast-growing (FG) scallops slow-growing (SG) scallops, 613, 509, 105, 192 significantly metabolites (SDMs) identified mantle, gill, adductor muscle, digestive gland, respectively. Growth-related pathways including sphingolipid metabolism, fatty acid biosynthesis, ABC transporter pathway, along 11 SDMs associated all four tissues, implying they involved scallops. Tissue-specific profiling indicated sulfur-containing amino metabolism mantle potentially contributed to shell growth, while gill synergistically participated through various processes, such as tyrosine glycine, serine, threonine melanogenesis; energy was crucial muscle growth; nutrients digestion absorption gland linked scallop growth. Our results first comprehensive analysis C. farreri, offering valuable insights future production.
