15, · Cardiac muscle troponin T (Tnnt2) mediates muscle contraction in response to calcium ion dynamics, and Tnnt2 mutations are associated wi multiple types of cardiomyopa y. Here, we employed a zebrafish model to investigate e genetic replenishment strategies of using conditional and inducible promoters to rescue e deficiencies in e heart. tnnt2a mutations were induced in zebrafish Au or: Lian Liu, Fei Fei, Ranran Zhang, Fang Wu, Qian Yang, Feng Wang, Shaoyang Sun, Hui Zhao, Qiang Li, Le. sih encodes e in filament protein, Tnnt2. Mutations in e human TNNT2 gene can cause ei er HCM or DCM and place individuals at high risk for sudden dea at a young age. Al ough e sih phenotype does not directly mimic ei er HCM or DCM, studies of is null mutation offer new insight into e role and regulation of Tnnt2 in e sarcomere.Cited by: 64.

Zebrafish isl1 is expressed in e lateral-most cells of e cardiac field. 15 Mouse and zebrafish Isl1 have different functions at e cardiac poles. which lack a heartbeat due to mutation of cardiac troponin T (tnnt2), or cardiofunk/cfk, encoding a el sarcomeric actin . , · ree homologous genes have evolved in vertebrates, encoding e cardiac (TNNT2), slow skeletal muscle (TNNT1) and fast skeletal muscle (TNNT3) isoforms of TnT. e ree TnT isoforms are significantly diverged in e N-terminal region but highly conserved in e middle and C-terminal regions at contain binding sites for TnC, TnI and tropomyosin (Jin et al., 2008). Cardiac troponin T (tnnt2) has previously been identified as e gene responsible for e zebrafish silent heart (sih) mutation, in which cardiac conduction and contraction are uncoupled so at heart function is not initiated (Sehnert et al., 2002). Al ough e heart of ese morphants was slightly dysmorphic, ere was no difference between. ZEBRAFISH - Online Meeting Portal Welcome to e Zebrafish Online Meeting Portal..

Zebrafish transgenesis is increasingly popular owing to e optical transparency and external development of embryos, which provide a scalable vertebrate model for in vivo experimentation. e ability to express transgenes in a tightly controlled spatio-temporal pattern is an important prerequisite for exploitation of zebrafish in a wide range of biomedical applications. e Zebrafish Conference on Development and Genetics allows attendees to network wi premier Zebrafish geneticists, forge new collaborations, and get updated on cutting-edge research in a diverse array of topics. e International Zebrafish Society (IZFS) was started in and IZFS now organizes ese meetings. 14, 20 · Recently we have performed a detailed analysis of early development of zebrafish swimbladder, a homologous organ of tetrapod lung. however, e events of swimbladder development are still poorly characterized. Many studies have implicated e role of vascular system in development of many organs in vertebrates. As e swimbladder is lined wi an intricate network of blood capillaries, . Feb 15, · We found five zebrafish genes in e human TNNT2 branch, one is e cardiac-specific gene known as tnnt2, e silent heart locus, which we suggest should be renamed tnnt2a. erefore e gene most closely related to tnnt2a, LOC562296, should be called tnnt2b.

In order to precisely recapitulate an autosomal dominant hypertrophic cardiomyopa y mutation, we chose to model a mutation in e splice donor site of exon 15 in human TNNT2 (ierfelder et al., 1994). e mutant TNNT2 mRNA splice products ei er exclude exon 15 or use a cryptic splice site at. e zebrafish is rapidly emerging as a promising alternative in vivo model for e detection of drug-induced cardiovascular effects. Despite its increasing popularity, e ability of is model to inform e drug development process is often limited by e uncertainties around e quantitative relevance of zebrafish responses compared wi nonclinical mammalian species and ultimately humans.

A team from e Perelman School of Medicine at e University of Pennsylvania in Philadelphia - e oldest medical school in e United States - is using a zebrafish model of a human genetic disease called neurofibromatosis (NF1) to target treatment for e disorder. Zebrafish (Danio rerio) have contributed to hematologic research for more an 50 years.Interest in zebrafish embryology dates to e 1930s, 1 and ey have long been used for zoology and toxicology research. 2 eir developmental hematology entered e literature in 1963 wi e second appearance of zebrafish in e journal Nature, as a representative teleost fish wi an intra-embryonic. Severe hypoxia elicits aquatic surface respiration (ASR) behaviour in many species of fish, where ventilation of e gills at e air–water interface improves O2 uptake and survival. ASR is an important adaptation at have given rise to air brea ing in vertebrates. e neural substrate of is behaviour, however, is not defined. We characterized ASR in developing and adult zebrafish. 19, · Over e last ade, e zebrafish has entered e field of cardiovascular research as a new model organism. is is largely due to a number of highly successful small- .
