Abstract
Enteritis is one of the main diseases affecting Pacific whiteleg shrimp (Litopenaeus vannamei) in recent years, and it has resulted in huge losses to the aquaculture industry. Prior to this study, the molecular mechanism underlying enteritis in L. vannamei was unclear, and comprehensive multi-omics analysis had not been conducted. In this study, 1209 differentially expressed genes (DEGs) were identified from the hepatopancreas of L. vannamei with and without enteritis. Kyoto Encyclopedia of Genes and Genomes analysis showed that genes were significantly enriched in immune, metabolic, and endocrine regulatory pathways. Forty-eight significantly different microRNAs (miRNAs) were identified in the miRNA-Seq analysis. Further functional annotation analysis showed that the regulatory pathway of target gene enrichment of differentially expressed miRNAs was consistent with DEGs. Through miRNA-mRNA integration analysis, 47 meaningful miRNA-mRNA pairs were obtained, of which melanogenesis and pancreatic secretion were considered key pathways. Subsequent miRNA-mRNA interaction network analysis revealed that mja-miR-6493-3p, Mja-miR-6494, novel-198, novel-272, novel-261, novel-200, novel-183, novel-184, novel-237, and novel-192 may be key miRNAs involved in the regulation of these two signaling pathways. Finally, the RAS signaling pathway was found to inhibit the translation level of proteins in the hepatopancreas. These results suggest that target gene integration analysis of mRNA-miRNA can reveal the molecular mechanism underlying enteritis in L. vannamei and also provide valuable new insights for resisting enteritis.

Regulation of Tyrosinase Gene Expression by Retinoic Acid Pathway in the Pacific Oyster Crassostrea gigas. Int J Mol Sci 2022; 23:12840. [PMID: 36361629 PMCID: PMC9656583 DOI: 10.3390/ijms232112840] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 09/28/2022] [Accepted: 10/19/2022] [Indexed: 08/26/2023] Open
Abstract
Retinoic acid (RA) plays important roles in various biological processes in animals. RA signaling is mediated by two types of nuclear receptors, namely retinoic acid receptor (RAR) and retinoid x receptor (RXR), which regulate gene expression by binding to retinoic acid response elements (RAREs) in the promoters of target genes. Here, we explored the effect of all-trans retinoic acid (ATRA) on the Pacific oyster Crassostera gigas at the transcriptome level. A total of 586 differentially expressed genes (DEGs) were identified in C. gigas upon ATRA treatment, with 309 upregulated and 277 downregulated genes. Bioinformatic analysis revealed that ATRA affects the development, metabolism, reproduction, and immunity of C. gigas. Four tyrosinase genes, including Tyr-6 (LOC105331209), Tyr-9 (LOC105346503), Tyr-20 (LOC105330910), and Tyr-12 (LOC105320007), were upregulated by ATRA according to the transcriptome data and these results were verified by real-time quantitative polymerase chain reaction (RT-qPCR) analysis. In addition, increased expression of Tyr (a melanin-related TYR gene in C. gigas) and Tyr-2 were detected after ATRA treatment. The yeast one-hybrid assay revealed the DNA-binding activity of the RA receptors CgRAR and CgRXR, and the interaction of CgRAR with RARE present in the Tyr-2 promoter. These results provide evidence for the further studies on the role of ATRA and the mechanism of RA receptors in mollusks.

COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY D-GENOMICS & PROTEOMICS 2021; 37:100788. [PMID: 33516925 DOI: 10.1016/j.cbd.2020.100788] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 12/22/2020] [Accepted: 12/22/2020] [Indexed: 11/28/2022]
Abstract
Tyrosinase (EC1.14.18.1, TYR) is also called phenol oxidase, is not only involved in pigmentation but also plays an important role in modulating innate immunity in invertebrates. Tyrosinase is a copper containing metalloenzyme. The tyrosinase protein has two copper binding sites and three conserved histidines. In this study, 21 tyrosinase genes (RpTYR) were obtained from the whole genome of Ruditapes philippinarum. Their open reading frames were from 951 to 5424 aa, the range of predicted relative molecular weight from 36.72 to 203.81 kDa, and the range of isoelectric point from 4.72 to 9.88. Transcriptome analysis showed that RpTYR gene was expressed specifically in different developmental stages, adult tissues, four strains and two groups with different shell colors. Besides, the expression profiles of 21 RpTYRs were investigated against the immune response of R. philippinarum to a Vibrio challenge. The qPCR results showed that RpTYRs were involved in the immune response of R. philippinarum after Vibrio anguillarum challenge. This study provides preliminary evidence that the tyrosinases genes are involved in the immune defense and the potential immune function of R. philippinarum. Overall, these findings suggested that the expansion of TYR genes may play vital roles in larval development, the formation of shell color pattern, and immune response in R. philippinarum.

Genomics 2020; 112:3636-3647. [PMID: 32353476 DOI: 10.1016/j.ygeno.2020.04.020] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2020] [Revised: 03/23/2020] [Accepted: 04/24/2020] [Indexed: 01/19/2023]
Abstract
Color plays a vital function in camouflage, sexual selection, immunity, and evolution. Mollusca possess vivid shell colors and pigmentation starts at the juvenile stage. The hard clam Mercenaria mercenaria is a widely cultivated bivalve of high economic value. To explore the molecular mechanism of pigmentation in juvenile clams, here, we performed RNA-Seq analysis on non-pigmented, white, and red M. mercenaria specimens. Clean reads were assembled into 358,285 transcripts and 149,234 unigenes, whose N50 lengths were 2107 bp and 1567 bp, respectively. Differentially expressed genes were identified and analyzed for KEGG enrichment. "Melanoma/Melanogenesis", "ABC transporters", and "Porphyrin and chlorophyll metabolism" pathways appeared to be associated with pigmentation. Pathways related to carotenoid metabolism seemed to also play a vital role in pigmentation in juveniles. Our results provide new insights into the formation of shell color in juvenile hard clams.
