Abstract
Live food is necessary for the proper development of zebrafish larvae, providing nutrition in a form that is easily digestible and available to the larvae. Live food is commonly enriched to increase the dietary content of certain nutrients. However, little research has been done on protein-based enrichments, especially those of plant origin. This study sought to examine how different quality protein enrichments affected the composition of live food as well as growth and digestive tract development of larval zebrafish, Danio rerio. Larval zebrafish were fed from 3 to 22 days posthatch (dph) with one of six live food (rotifers Brachionus plicatilis and Artemia spp.) treatments: (1) live food with no enrichment (starved; control); (2) live food enriched with commercially used Spirulina spp. algae; (3) live food enriched with soybean meal (SBM); (4) live feed enriched with soy protein concentrate (SPC); (5) live feed enriched with a fishmeal hydrolysate; and (6) live feed enriched with intact fishmeal (FM). Proximate composition of live food was significantly affected by enrichment, in particular, protein content of rotifers was significantly increased by enrichment with SBM. Zebrafish fed SBM-enriched live food showed longer total body length than all other groups, except SPC. Zebrafish in the SBM group also showed increased gene expression of chymotrypsin in the intestine, possibly indicating improved intestinal development and extracellular digestion, which likely contributed to improved growth. Conversely, zebrafish fed hydrolysate-enriched live food showed reduced gene expression of alkaline phosphatase, possibly indicating a less developed intestinal tract, correlating with reduced growth compared to SBM group. Overall, plant protein was shown to be a promising source of live food enrichment for improving larval zebrafish growth.

BACH family members regulate angiogenesis and lymphangiogenesis by modulating VEGFC expression. Life Sci Alliance 2020; 3:e202000666. [PMID: 32132179 PMCID: PMC7063472 DOI: 10.26508/lsa.202000666] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2020] [Revised: 02/23/2020] [Accepted: 02/24/2020] [Indexed: 12/23/2022] Open
Abstract
Angiogenesis and lymphangiogenesis are key processes during embryogenesis as well as under physiological and pathological conditions. Vascular endothelial growth factor C (VEGFC), the ligand for both VEGFR2 and VEGFR3, is a central lymphangiogenic regulator that also drives angiogenesis. Here, we report that members of the highly conserved BACH (BTB and CNC homology) family of transcription factors regulate VEGFC expression, through direct binding to its promoter. Accordingly, down-regulation of bach2a hinders blood vessel formation and impairs lymphatic sprouting in a Vegfc-dependent manner during zebrafish embryonic development. In contrast, BACH1 overexpression enhances intratumoral blood vessel density and peritumoral lymphatic vessel diameter in ovarian and lung mouse tumor models. The effects on the vascular compartment correlate spatially and temporally with BACH1 transcriptional regulation of VEGFC expression. Altogether, our results uncover a novel role for the BACH/VEGFC signaling axis in lymphatic formation during embryogenesis and cancer, providing a novel potential target for therapeutic interventions.

Abstract
MicroRNAs (miRNAs), as important regulators of post-transcriptional gene expression, play important roles in the occurrence and function of organs. In this study, morpholino (MO) knockdown of miR-462/miR-731 was used to investigate the potential mechanisms of the miR-462-731 cluster during zebrafish liver development. The results showed significant reduction of digestive organs, especially liver and exocrine pancreas after the miR-462/miR-731 knockdown, and those phenotypes could be partially rescued by corresponding miRNA duplex. Acinar cells of the exocrine pancreas were also severely affected with pancreatic insufficiency. In particular, knockdown of miR-462 caused pancreas morphogenesis abnormity with specific bilateral exocrine pancreas. Additionally, it was found that miR-731 played a role in liver and exocrine pancreas development by directly targeting dkk3b, instead of the down-regulation of Wnt/β-catenin signaling. These findings contribute significantly to our understanding of molecular mechanisms of miR-462-731 cluster in development of digestive organs.

Abstract
Iron overload increases the risk of osteoporosis, which leads to an increase in the incidences of bone fracture after menopause. In vitro studies have demonstrated that excess iron can inhibit osteoblast activity. Hepcidin, a central regulator of iron homeostasis, prevents iron overload, and thus, it is considered to have anti-osteoporosis effects. In this study, a zebrafish model was employed to investigate the therapeutic role of hepcidin in iron overload-induced inhibition of bone formation. Our results show that ferric ammonium citrate (FAC) treatment decreased osteoblast-specific gene expression (runx2a, runx2b, and bglap) and bone mineralization in the zebrafish embryo, accompanied with increased whole-body iron levels and oxidative stress. Bone mineralization and osteoblast-specific gene expression increased with the microinjection of hepcidin-flag Capped-mRNA into zebrafish embryos. Moreover, the whole-body iron content and oxidative stress in the iron-overloaded zebrafish embryos decreased when microinjection of hepcidin preceded the FAC treatment. Therefore, our study suggests that hepcidin could prevent and rescue reduced bone formation caused by FAC treatment by preventing iron absorption.

Abstract
Vertebrate embryonic development requires specific signaling events that regulate cell proliferation and differentiation to occur at the correct place and the correct time in order to build a healthy embryo. Signaling pathways are sensitive to perturbations of the endogenous redox state, and are also susceptible to modulation by reactive species and antioxidant defenses, contributing to a spectrum of passive vs. active effects that can affect redox signaling and redox stress. Here we take a multi-level, integrative approach to discuss the importance of redox status for vertebrate developmental signaling pathways and cell fate decisions, with a focus on glutathione/glutathione disulfide, thioredoxin, and cysteine/cystine redox potentials and the implications for protein function in development. We present a tissue-specific example of the important role that reactive species play in pancreatic development and metabolic regulation. We discuss NFE2L2 (also known as NRF2) and related proteins, their roles in redox signaling, and their regulation of glutathione during development. Finally, we provide examples of xenobiotic compounds that disrupt redox signaling in the context of vertebrate embryonic development. Collectively, this review provides a systems-level perspective on the innate and inducible antioxidant defenses, as well as their roles in maintaining redox balance during chemical exposures that occur in critical windows of development.

Abstract
Copper nanoparticles (CuNPs) are used widely due to their attractive antimicrobial properties. However, their biosafety and kinetics on vertebrate embryogenesis are still limited. In this study, CuNPs were revealed to induce eye hypoplasia and almost no digestive gut in zebrafish embryos in a dose-dependent manner. Then, transcriptional responses of zebrafish embryos to CuNPs were investigated, and it was revealed that the genes related to wound healing and stimulus responses were up-regulated, but the genes associated with phototransduction and metabolisms were down-regulated. Differentially expressed genes (DEGs) in CuNPs-exposed and Cu2+-exposed embryos were compared further. Increased VEGF signaling and expression of fli1 were observed in CuNPs rather than Cu2+ treated embryos, but increased reactive oxygen species (ROS) and the resulting enhanced hemoglobin were observed in both CuNPs and Cu2+ treated embryos. This study for the first time revealed that CuNPs and Cu2+ both down-regulated the genes related to phototransduction and metabolisms, but up-regulated the genes associated with hemoglobin. Additionally, compared with Cu2+, CuNPs might be more effective in elevating blood vessels in embryos. Our results suggest that the biological effects of CuNPs are organogenesis-specific during fish embryogenesis, and both particles and ions might mediate their biological effects on embryogenesis.

Abstract
Bach1 disrupts Wnt/β-catenin signaling, reduces the proliferation, migration, and tube formation activity of endothelial cells (ECs), and suppresses angiogenesis in mice with surgically induced hind-limb ischemia (HLI). However, the function of Bach1 during developmental angiogenesis in zebrafish remains unclear. Here, we found that zebrafish Bach1 was expressed ubiquitously during early embryonic development in zebrafish. Bach1b mRNA injection of Tg(fli1:gfp) fish disrupted intersegmental vessels (ISV) and dorsal longitudinal anastomotic vessels (DLAV) and suppressed endogenous Wnt/β-catenin signaling and Wnt8a stimulated vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8) gene expression at early embryonic stages of zebrafish. Furthermore, chromatin immunoprecipitation experiments confirmed that Bach1 occupied the TCF/LEF-binding site of the VEGF promoter in human umbilical vein endothelial cells (HUVECs). Bach1 inhibited VEGF transcription by recruiting histone deacetylase 1 (HDAC1) to the VEGF promoter in HUVECs. Exogenous administration of VEGF or IL-8 partially rescued Bach1-driven antiangiogenic functions in HUVECs. Taken together, these observations indicate that Bach1 suppresses the developmental angiogenesis of zebrafish and that this function is associated with declines in Wnt/β-catenin signaling and VEGF and IL-8 expression.

Abstract
Background The common carp (Cyprinus carpio) is the oldest, most domesticated and one of the most cultured fish species for food consumption. Besides its economic importance, the common carp is also highly suitable for comparative physiological and disease studies in combination with the animal model zebrafish (Danio rerio). They are genetically closely related but offer complementary benefits for fundamental research, with the large body mass of common carp presenting possibilities for obtaining sufficient cell material for advanced transcriptome and proteome studies. Results Here we have used 19 different tissues from an F1 hybrid strain of the common carp to perform transcriptome analyses using RNA-Seq. For a subset of the tissues we also have performed deep proteomic studies. As a reference, we updated the European common carp genome assembly using low coverage Pacific Biosciences sequencing to permit high-quality gene annotation. These annotated gene lists were linked to zebrafish homologs, enabling direct comparisons with published datasets. Using clustering, we have identified sets of genes that are potential selective markers for various types of tissues. In addition, we provide a script for a schematic anatomical viewer for visualizing organ-specific expression data. Conclusions The identified transcriptome and proteome data for carp tissues represent a useful resource for further translational studies of tissue-specific markers for this economically important fish species that can lead to new markers for organ development. The similarity to zebrafish expression patterns confirms the value of common carp as a resource for studying tissue-specific expression in cyprinid fish. The availability of the annotated gene set of common carp will enable further research with both applied and fundamental purposes.

Abstract
Iron overload, as a risk factor for osteoporosis, can result in the up-regulation of Hepcidin, and Hepcidin knockout mice display defects in their bone microarchitecture. However, the molecular and genetic mechanisms underlying Hepcidin deficiency-derived bone loss remain unclear. Here, we show that hepcidin knockdown in zebrafish using morpholinos leads to iron overload. Furthermore, a mineralization delay is observed in osteoblast cells in hepcidin morphants, and these defects could be partially restored with microinjection of hepcidin mRNA. Quantitative real-time PCR analyses revealed the osteoblast-specific genes alp, runx2a, runx2b, and sp7 in morphants are down-regulated. Furthermore, we confirmed qRT-PCR results by in situ hybridization and found down-regulated genes related to osteoblast function in hepcidin morphants. Most importantly, we revealed that hepcidin was capable of removing whole-body iron which facilitated larval recovery from the reductions in bone formation and osteogenesis induced by iron overload.

Abstract
The spatial-temporal expressions of bach1a, bach1b, bach2a and bach2b in early development of zebrafish Danio rerio embryos were examined in the present study by whole mount in situ hybridization. Transcripts of all genes were found at the one cell stage, suggesting that these four genes are maternally inherited. From the phylogenetic analyses, Bach1a and Bach1b from fishes form a well-supported group with two sub-groups. Bach2a and Bach2b, however, did not fall into one clade, suggesting that Bach2 proteins diverged faster or earlier than Bach1 proteins in fishes. The differentially regulated expression of the exocrine zymogen (such as the trypsin-like gene, tryl) of both paralogs of bach1 and bach2, respectively, showed that their functions are still active and already divergent, coinciding with subfunction partitioning.

Abstract
Oxidative stress is an important mechanism of chemical toxicity, contributing to developmental toxicity and teratogenesis as well as to cardiovascular and neurodegenerative diseases and diabetic embryopathy. Developing animals are especially sensitive to effects of chemicals that disrupt the balance of processes generating reactive species and oxidative stress, and those anti-oxidant defenses that protect against oxidative stress. The expression and inducibility of anti-oxidant defenses through activation of NFE2-related factor 2 (Nrf2) and related proteins is an essential process affecting the susceptibility to oxidants, but the complex interactions of Nrf2 in determining embryonic response to oxidants and oxidative stress are only beginning to be understood. The zebrafish (Danio rerio) is an established model in developmental biology and now also in developmental toxicology and redox signaling. Here we review the regulation of genes involved in protection against oxidative stress in developing vertebrates, with a focus on Nrf2 and related cap'n'collar (CNC)-basic-leucine zipper (bZIP) transcription factors. Vertebrate animals including zebrafish share Nfe2, Nrf1, Nrf2, and Nrf3 as well as a core set of genes that respond to oxidative stress, contributing to the value of zebrafish as a model system with which to investigate the mechanisms involved in regulation of redox signaling and the response to oxidative stress during embryolarval development. Moreover, studies in zebrafish have revealed nrf and keap1 gene duplications that provide an opportunity to dissect multiple functions of vertebrate NRF genes, including multiple sensing mechanisms involved in chemical-specific effects.

Heme-mediated inhibition of Bach1 regulates the liver specificity and transience of the Nrf2-dependent induction of zebrafish heme oxygenase 1. Genes Cells 2015; 20:590-600.

Abstract
The induction of the gene encoding heme oxygenase 1 (Hmox1, HO-1) by Nrf2 is unique compared with other Nrf2 targets. We previously showed that the Nrf2a-mediated induction of zebrafish hmox1a was liver specific and transient. We screened transcription factors that could repress the induction of hmox1a but not other Nrf2a targets and concluded that Bach1b was a prime candidate. In bach1b-knocked-down larvae, the induction of hmox1a was observed ectopically in nonliver tissues and persisted longer than normal fish, suggesting that Bach1 is the only regulator for both the liver-specific and transient induction of hmox1a. Co-knockdown of bach1b with its co-ortholog bach1a enhanced these effects. To determine why Bach1 could not repress the hmox1a induction in the liver, we analyzed the effects of a heme biosynthesis inhibitor, succinylacetone, and a heme precursor, hemin. Succinylacetone decreased the Nrf2a-mediated hmox1a induction, whereas pre-treatment with hemin caused ectopic induction of hmox1a in nonliver tissues, implying that the high heme levels in the liver may release the repressive activity of Bach1. Our results suggested that Bach1 regulates the liver specificity and transience of the Nrf2a-dependent induction of hmox1a and that heme mediates this regulation through Bach1 inhibition based on its level in each tissue.
