The Mexican tetra, Astyanax mexicanus, exists as eyed surface and blind cave dwelling populations. The opportunity for comparative approaches between independently evolved populations has led to the rapid growth of A. mexicanus as a model for evolution and biomedical research. However, a slow and inconsistent growth rate remains a major limitation to the expanded application of A. mexicanus. Fortunately, this temporal limitation can be addressed through husbandry changes that accelerate growth rates while maintaining optimal health outcomes. Here, we describe a husbandry protocol that produces rapid growth rates through changes in diet, feeding frequency, growth sorting and progressive changes in tank size. This protocol produced robust growth rates and decreased the age of sexual maturity in comparison to our previous protocol. To determine whether changes in feeding impacted behavior, we tested fish in exploration and schooling assays. We found no difference in behavior between the two groups, suggesting that increased feeding and rapid growth will not impact the natural variation in behavioral traits. Taken together, this standardized husbandry protocol will accelerate the development of A. mexicanus as a genetic model.","PeriodicalId":23872,"journal":{"name":"Zebrafish","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10123811/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10038004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the motoneuron-dependent swim-up behavior is important for swim bladder inflation, the underlying molecular mechanism remains largely unknown. We generated a sox2 KO zebrafish using TALEN and found that the posterior chamber of the swim bladder was uninflated. The tail flick and the swim-up behavior were absent in the mutant zebrafish embryos and the behavior could not be accomplished. As the tail flick behavior is absent, the mutant larvae therefore cannot reach the water surface to gulp air, ultimately leading to the uninflation of the swim bladder. To understand the mechanism underlying the swim-up defects, we crossed the sox2 null allele in the background of Tg(huc:eGFP) and Tg(hb9:GFP). The deficiency of sox2 in zebrafish resulted in abnormal motoneuron axons in the regions of trunk, tail, and swim bladder. To identify the downstream target gene of sox2 to control the motor neuron development, we performed RNA sequencing on the transcriber of mutant embryos versus wild type embryos and found that the axon guidance pathway was abnormal in the mutant embryos. RT-PCR demonstrated that the expression of sema3bl, ntn1b, and robo2 were decreased in the mutants.","PeriodicalId":23872,"journal":{"name":"Zebrafish","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/bb/88/zeb.2022.0043.PMC9968866.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9423413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of dispersed signals of histones H2A, H2B, H3, and H4 in the karyotype of both species, with each sequence displaying a varied level of accumulation and dispersion of these sequences between them was observed; in addition, U2 snDNA probe only showed positive results in H. zebra, which present this multigene in the terminal region of three chromosomal pairs. The obtained results resemble data already analyzed in the literature, in which the action of transposable elements interfere in the organization of these multigene families, in addition to other evolutionary processes that shape the evolution of the genome, such as circular or ectopic recombination.

Currently, the use of molecular tools has proved to be fundamental in aiding phylogenetics and cataloging biodiversity; therefore, in this study, we molecularly characterize a possible new species of Cnesterodon from the Ivaí River basin encoding the mitochondrial genes Cytochrome c Oxidase, subunit I (COI), and NADH dehydrogenase subunit 2 (ND2). The genetic differences found showed that this species really differs from the other Cnesterodon species, indicating that it is a distinct species, which is possibly already in serious danger of extinction since its habitat often suffers from human exploitation and its distribution is restricted to only two sites in the upper Ivaí River basin, but it has disappeared in one of them.","PeriodicalId":23872,"journal":{"name":"Zebrafish","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9968864/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10864985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, exceptionally high levels of MET and its metabolites in plasma have been found to be toxic and can lead to cell alterations. Long-term exposure to MET has been shown to mimic psychotic symptoms in schizophrenic patients and rodents. The present study evaluated behavioral and neurochemical effects of long-term exposure to MET in zebrafish. Five groups of zebrafish were exposed to MET at a concentration of 4.5 mM for 7 days, along with acute exposure to 25 μM of clozapine and 750, 1000, and 1250 μM of metoclopramide. In contrast, the normal group was exposed to only water and dimethyl sulfoxide. After the treatment, social interaction, anxiety, memory, and locomotion of zebrafish and serotonin levels in zebrafish brains were evaluated. Our results showed that metoclopramide was not only beneficial in improving MET-induced cognitive impairment but it also prevented social withdrawal in zebrafish exposed to MET. In addition, metoclopramide reversed anxiety-like behavior, as indicated by significant changes in locomotion activity. Despite slight changes in serotonin levels in the zebrafish brain, an in vitro serotonin assay failed to demonstrate significant differences between the disease control, normal, and two treatment groups. Finally, results from the study showed that repeated administration of MET induced schizophrenia-like symptoms, although metoclopramide ameliorated the MET-mediated negative symptoms and cognitive deficits in zebrafish. Overall, our findings suggest a new perspective to further explore the antipsychotic properties of metoclopramide.","PeriodicalId":23872,"journal":{"name":"Zebrafish","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9447912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Environmental enrichment has been shown to improve welfare and health of a large number of species of animals studied in laboratories, kept in zoos, or used in agriculture. However, most laboratories keep zebrafish in barren tanks. Artificial and live aquatic plants have been used in a variety of contexts for aquarium fish, and they have also been suggested as a potential enrichment strategy for the zebrafish. However, no systematic studies have been conducted to investigate their beneficial effects in zebrafish husbandry and biology research. In this study, we review some of the potential benefits of using live plants, and argue that systematic analyses for proper choice and use of live plants in zebrafish husbandry are sorely needed. We provide a few examples of aquatic plant species out of the large variety produced for the aquarium hobby that could be adopted to the zebrafish laboratory setting as environmental enrichment. We speculate that once systematic analyses have been conducted, they will show benefits of this ethologically/ecologically relevant enrichment method, one of which will be healthier and less stressed fish leading to increased reproducibility of results in zebrafish research.","PeriodicalId":23872,"journal":{"name":"Zebrafish","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10576446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
