The Probiotic Phaeobacter inhibens Provokes Hypertrophic Growth via Activation of the IGF-1/Akt Pathway during the Process of Metamorphosis of Greater Amberjack ( Seriola dumerili, Risso 1810). Animals (Basel) 2023; 13:2154. [PMID: 37443952 DOI: 10.3390/ani13132154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 06/04/2023] [Accepted: 06/27/2023] [Indexed: 07/15/2023] Open
Abstract
Metamorphosis entails hormonally regulated morphological and physiological changes requiring high energy levels. Probiotics as feed supplements generate ameliorative effects on host nutrient digestion and absorption. Thereby, the aim of the present research was to investigate the impact of the probiotic Phaeobacter inhibens as a water additive on cellular signaling pathways in the metamorphosis of greater amberjack (Seriola dumerili). Activation of insulin-like growth factor type 1 receptor (IGF-1R), protein kinase B (Akt), mitogen-activated protein kinases (MAPKs) and AMP-activated protein kinase (AMPK), induction of heat shock proteins (Hsps), and programmed cell death were assessed through SDS-Page/immunoblot analysis, while energy metabolism was determined through enzymatic activities. According to the results, greater amberjack reared in P. inhibens-enriched water entered the metamorphic phase with greater body length, while protein synthesis was triggered to facilitate the hypertrophic growth as indicated by IGF-1/Akt activation and AMPK inhibition. Contrarily, MAPKs levels were reduced, whereas variations in Hsps response were evident in the probiotic treatment. Apoptosis and autophagy were mobilized potentially for the structural remodeling processes. Furthermore, the elevated enzymatic activities of intermediary metabolism highlighted the excess energy demands of metamorphosis. Collectively, the present findings demonstrate that P. inhibens may reinforce nutrient utilization, thus leading greater amberjack to an advanced growth and developmental state.

Abstract
Insulin-like growth factor-1 receptors (igf1rs) play important roles in regulating development, differentiation, and proliferation in diverse organisms. In the present study, subtypes of medaka igf1r, igf1ra, and igf1rb were isolated and characterized. RT-PCR results showed that igf1ra and igf1rb mRNA were expressed in all tissues and throughout embryogenesis. Using real-time PCR, the differential expression of igf1ra and igf1rb mRNA during folliculogenesis was observed. The results of in situ hybridization (ISH) revealed that both of them were expressed in ovarian follicles at different stages, and igf1rb was also expressed in theca cells and granulosa cells. In the testis, both igf1ra and igf1rb mRNA were highly expressed in sperm, while igf1rb mRNA was also obviously detected in spermatogonia. In addition, igf1ra mRNA was also present in Leydig cells in contrast to the distribution of igf1rb mRNA in Sertoli cells. Collectively, we demonstrated that differential igf1rs RNA expression identifies medaka meiotic germ cells and somatic cells of both sexes. These findings highlight the importance of the igf system in the development of fish gonads.

Abstract
Many genes related to muscle growth modulate myoblast proliferation and differentiation and promote muscle hypertrophy. MyoD is a myogenic determinant that contributes to myoblast determination, and insulin-like growth factor 1 (IGF-I) interacts with MyoD to regulate muscle hypertrophy and muscle mass. In this study, we aimed to assess DNA methylation and mRNA expression patterns of MyoD and IGF-I during different developmental stages of Japanese flounder, and to examine the relationship between MyoD and IGF-I gene. DNA and RNA were extracted from muscles, and DNA methylation of MyoD and IGF-I promoter and exons was detected by bisulfite sequencing. The relative expression of MyoD and IGF-I was measured by quantitative polymerase chain reaction. IGF-I was measured by radioimmunoassay. Interestingly, the lowest expression of MyoD and IGF-I emerged at larva stage, and the mRNA expression was negatively associated with methylation. We hypothesized that many skeletal muscle were required to complete metamorphosis; thus, the expression levels of MyoD and IGF-I genes increased from larva stage and then decreased. The relative expression levels of MyoD and IGF-I exhibited similar patterns, suggesting that MyoD and IGF-I regulated muscle growth through combined effects. Changes in the concentrations of IGF-I hormone were similar to those of IGF-I gene expression. Our results the mechanism through which MyoD and IGF-I regulate muscle development and demonstrated that MyoD interacted with IGF-I to regulate muscle growth during different developmental stages.

The complete salmonid IGF-IR gene repertoire and its transcriptional response to disease. Sci Rep 2016; 6:34806.

Abstract
The insulin-like growth factor (IGF) receptor (IGF-IR) is necessary for IGF signalling and has essential roles in cellular growth. In teleost fish, two distinct IGF-IR duplicates are conserved called IGF-IRa and IGF-IRb. However, while a salmonid-specific whole genome duplication (ssWGD) is known to have expanded several key genes within the IGF axis, its impact on the IGF-IR repertoire remains unresolved. Using bioinformatic and phylogenetic approaches, we establish that salmonids retain two IGF-IRa paralogues from ssWGD and a single IGF-IRb copy. We measured the tissue-specific and developmental transcriptional regulation of each IGF-IR gene, revealing tight co-expression between the IGF-IRa paralogues, but expression divergence comparing IGF-IRa and IGF-IRb genes. We also examined the regulation of each IGF-IR gene in fish challenged by bacterial and viral infections, adding to recent reports that the IGF axis has roles linking growth and immunity. While whole salmonid fry showed a small upregulation of IGF-IR expression during both types of infection, bacterial challenge caused striking downregulation of IGF-IRa1 and IGF-IRa2 in head kidney and spleen of adult fish, alongside genes coding IGF hormones, highlighting a strong repression of IGF-signalling in primary immune tissues. The reported immune-responsive regulation of IGF-IR genes adds to an emerging body of evidence that supports important cross-talk between master growth and immune pathways in vertebrates.

Molecular cloning, expression profiles and promoter analysis of insulin-like growth factor binding protein-4 (IGFBP-4) in Japanese flounder (Paralichthys olivaceus). Comp Biochem Physiol B Biochem Mol Biol 2014; 175:41-52. [PMID: 24984076 DOI: 10.1016/j.cbpb.2014.06.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2013] [Revised: 05/24/2014] [Accepted: 06/20/2014] [Indexed: 11/27/2022]
Abstract
We cloned and characterized cDNA sequence of insulin-like growth factor binding protein-4 (IGFBP-4) from Japanese flounder (Paralichthys olivaceus). The 1493 bp full-length cDNA sequence contained an open reading frame (ORF) of 780 bp, which encoded a protein of 259 amino acids. The deduced amino acid sequences included a putative signal peptide of 28 amino acid residues resulting in a mature protein of 231 amino acids. Twenty cysteine residues and two conserved IGFBPs motif (GCGCCXXC and CWCV) were found in the N- and C-terminal domain. In the over 13 kbp genomic sequence, four exons, three introns, and 5'-/3'-flanking sequences were identified. Sequence alignment and phylogenetic analysis showed that Japanese flounder IGFBP-4 was indeed the ortholog of the human IGFBP-4 gene and shared high identities with other teleost IGFBP-4 genes. The promoter region was also analyzed and several potential transcription factor (TF) binding sites were determined which may modulate the IGFBP-4 expression. Quantitative real-time PCR analysis revealed that IGFBP-4 mRNA was observed in various tissues, with intestine showing the highest expression. The maternal transcripts of IGFBP-4 gene existed in the early embryonic stages and then increased in the following stages until hatching, suggesting that IGFBP-4 may be involved in the fish early development. The expression level of IGFBP-4 mRNA was relatively higher at 3 days post hatching (dph) and 15 dph, and gradually decreased during the metamorphosis period. All these results indicated that IGFBP-4 plays a significant role in IGF regulating vertebrate growth and development.

Abstract
In this study, we cloned and characterized cDNA sequences of two insulin-like growth factor binding protein-2 (IGFBP-2a and IGFBP-2b) from Japanese flounder, Paralichthys olivaceus. The full-length cDNA of IGFBP-2a is 1,046 bp long and consists an open frame (ORF) of 876 bp, a 5'-untranslated region (UTR) of 125 bp and a 3'-UTR of 45 bp. IGFBP-2b is 1,067 bp, including a 5'-UTR of 53 bp, a 3'-UTR of 198 bp and an ORF of 816 bp. Real-time quantitative PCR results revealed that IGFBP-2a -2b mRNA was expressed in all detected tissues. Interestingly, the levels of IGFBP-2a mRNA in all detected tissues were higher in female than male, but IGFBP-2b was precisely the opposite. At different embryonic stages, the levels of IGFBP-2a mRNA were typically higher than IGFBP-2b. After hatching, IGFBP-2a mRNA was gradually decreased to a relatively lower level. However, the expression of IGFBP-2b mRNA was increased after hatching, including 3, 7, 10, 14, 17, 20 and 23 days post-hatching (dph), and it presents a higher level until 29 (metamorphic climax), 36 (post-climax) and 41 dph (the end of metamorphosis). In levothyroxine sodium salt (T4, the main form of thyroid hormone in animals)-treated and thiourea (TU)-treated larvae, the expressions of IGFBP-2a had not visibly changed, except in T4-treated 17 dph larvae. The expressions of IGFBP-2b mRNA were distinctly increased from 17 to 23 dph, but suddenly dropped to a lower level in and after 29 dph. However, the levels of IGFBP-2b mRNA during metamorphosis were greatly down-regulated after TU treatment. These results provided basic information for further studies on the role of IGF system in flatfish development and metamorphosis.

Abstract
Insulin-like growth factor binding protein-1 (IGFBP-1) plays an important role in IGF regulating vertebrate growth and development. In this study, we cloned IGFBP-1 cDNA from Japanese flounder (Paralichthys olivaceus) liver. The full-length cDNA is 1070 bp, including a 5'-untranslated region (UTR) of 69 bp, a 3'-UTR of 272 bp, and an open reading frame (ORF) of 729 bp encoding a polypeptide of 242 amino acids. Real-time quantitative PCR revealed that IGFBP-1 mRNA is mainly expressed in the liver, and a small amount of mRNAs was also found in other adult tissues. There are maternal transcripts of IGFBP-1 gene, and relatively low mRNA levels were observed in different embryonic stages. A higher level of IGFBP-1 mRNA was detected at 3 days post hatching (dph), and it got to the highest level at 29 dph (metamorphic climax), and finally brought back to a lower level at the end of metamorphosis. The expression of IGFBP-1 mRNA was greatly up-regulated in thyroid hormone (TH)-treated larvae, and declined after thiourea (TU) treatment. These results provide basic information for further studies on the role of IGF system in the P. olivaceus development and metamorphosis.
