Rodent models of AD have been exploited extensively and have given considerable insight into this disease. established as an excellent vertebrate model for the study of developmental biology and gene function. Their amino. However, the use of GSIs comes with the potential side affects of also affecting Notch signaling. (2012). The language interprets these to logical concepts and extracts functional relationships between proteins, small molecules, and cellular processes (Nikitin et al., 2003b; Novichkova et al., 2003a). Title: The Zebrafish Model: Use in Studying Cellular Mechanisms for a Spectrum of Clinical Disease Entities VOLUME: 4 ISSUE: 2 Author(s):Chi-Hsin Hsu, Zhi-Hong Wen, Chan-Shing Lin and Chiranjib Chakraborty Affiliation:Resources, College of Marine Science, National Sun Yat-sen University, Kaohisung, Taiwan. Both mutations affected ribosomal protein gene expression but in opposite directions. Moreover, autophagy-deficiency-induced neurodegeneration was exacerbated by amyloidosis, which together severely impaired memory. The zebrafish is becoming an increasingly popular model for the investigation of Alzheimer’s disease and will complement studies using other models to help complete our understanding of this disease.

There are a number of cellular pathways and processes that are aberrant in AD. doi: 10.1016/j.ydbio.2005.12.056, Rademakers, R., and Rovelet-Lecrux, A. Together, our data offered the first concreate evidences of structural integration and inheritance in peptide cross-seeding, a crucial knowledge gap in understanding the pathological correlations between different amyloid diseases. This review will focus on how the zebrafish has been used to study the genes and various cellular pathways implicated in FAD and SAD pathogenesis and will conclude by examining the limitations of the zebrafish and what the future may hold for use of this model in AD research.

Reverse genetic analysis of neurogenesis in the zebrafish retina. This supports the evolutionary conservation of function of these truncated proteins. negative effects of pathogenic PSEN1 mutations on gamma-secretase activity and, et al. The involvement of the purinergic system in several models of neurological disorders, such as Alzheimers disease, Parkinson's disease, epilepsy, schizophrenia, and autism has been investigated in zebrafish. However, instead of the (at that time) expected exon exclusion, injection of morpholinos blocking splice acceptor sites lead to the failure of introns 7 and 8 to be correctly spliced out of transcripts (Nornes et al., 2008). However, they could not detect the transcripts of these genes in the endothelial cells of the vasculature. doi: 10.1126/science.1132341, Wilson, L., and Lardelli, M. (2013). The Q(o) site of the mitochondrial complex III is required for the transduction of hypoxic signaling via reactive oxygen species production. However, this approach is mostly limited to mice among the vertebrate models because of the difficulty in establishing ES cells.

Single molecule profiling of tau gene expression in Alzheimer’s disease. These isoforms can be classified into two groups, 3R or 4R, depending on the number of tubulin-binding motifs. Presenilin 1 is required for Notch1 and DII1 expression in the paraxial mesoderm. Evaluation of exon-skipping strategies for Duchenne muscular dystrophy utilizing dystrophin-deficient zebrafish. Injection of mRNAs coding for proteins truncated after exon 6- or 7-derived sequence had the same dominant effect on Psen1 activity as the morpholino-induced aberrant psen1 transcripts. PLoS ONE 8:e67506. Both apolipoprotein E and A-I genes are present in a nonmammalian vertebrate and are highly expressed during embryonic development. Interestingly, similar effects were also observed after injection of synthetic mRNAs encoding equivalent truncations of human PSEN1. Aging 15, 347–352. To reconcile the dominant action of pathogenic PSEN1 mutations with evidence that they confer a loss of mutant protein function, we tested the hypothesis that PSEN1 mutations interfere with γ-secretase activity in a dominant-negative manner. Brain Dis. J. Neurochem. These overlap considerably with the risk factors for cardiovascular disease (Kotze and van Rensburg, 2012) including hypertension, hypercholesterolemia and obesity (Martins et al., 2006). Diseases with tau-like pathology are collectively termed “tauopathies.” A review by Bai and Burton (2011) discussed how the zebrafish has been used to investigate these diseases. A study by Cameron et al. The only published study that has generated a transgenic Aβ toxicity model in zebrafish involved fusing the human Aβ-42 sequence to the promoter of the mitfa (nacre) gene (Newman et al., 2010). Catchen, J. M., Braasch, I., and Postleth. The zebrafish “co-orthologs” of the human MAPT gene, mapta and maptb have similar but not completely overlapping patterns of expression in developing embryos (Chen et al., 2009). doi: 10.1111/jnc.12460, Selfridge, J. E., E, L., Lu, J., and Swerdlow, R. H. (2012). Various dysfunctions of the tau protein are found in other neurodegenerative disorders such as frontotemporal dementia (FTD), corticobasal degeneration and progressive supranuclear palsy (Pittman et al., 2006). doi: 10.1523/JNEUROSCI.0954-13.2013, Herreman, A., Hartmann, D., Annaert, W., Saftig, P., Craessaerts, K., Serneels, L., et al. doi: 10.1016/j.phrs.2003.12.028, Veth, K.

Once an Appa:GFP/ free GFP ratio is determined for a protein sample from a pool of manipulated embryos (e.g., drug treatment, morpholino or mRNA injection) it can then be compared to control embryos to determine how that particular manipulation is affecting γ-secretase cleavage activity. doi: 10.1083/jcb.201201076, Conrad, C., Zhu, J., Conrad, C., Schoenfeld, D., Fang, Z., Ingelsson, M., et al.
