A novel group of zebrafish Class II ADP-ribosylation factors and their potential role in photoreceptor development
DownloadFall 2013
In this study we identified an unknown set of Class II Arf isoforms in zebrafish. Bioinformatics analyses grouped these paralogues into three distinct clades. Using antisense morpholino gene knockdown, we tested the effect of loss of each zebrafish Class II Arf on early development and...

Analysis of Foxc1 Function During Somite Formation and Chondrogenesis of the Axial Skeleton
DownloadSpring 2018
Development of the axial skeleton in vertebrates begins with the segmentation of the paraxial mesoderm into somites. Somites are transient structures in the embryos that ultimately give rise to the skeletal muscle, dermis, tendons, cartilage, and bony structures of the axial skeleton. Once...

Aquatic nanotoxicity testing: Insights at the biochemical, cellular, and whole animal levels
DownloadFall 2013
Aquatic organisms are susceptible to waterborne nanoparticles and there is only limited understanding of the mechanisms by which these emerging contaminants affect biological processes. The unique properties of nanomaterials necessitate evaluation of standard toxicity testing techniques to...

Chaperone and Gene Regulatory Roles of SMYD1b during Early Skeletal Muscle Development and Heart Morphogenesis
DownloadFall 2017
Sarcomeres are the basic contractile units that make up the striated muscle of the heart and skeletal muscle. The specification and differentiation of muscle cells and the contractile function of the sarcomere are generally well understood, but how the sarcomere assembles remains largely unknown....

Normal eye development requires a complex series of morphological movements and ocular patterning with aberrant eye development resulting in birth defects and retinal dystrophies. Eleven percent of paediatric blindness is caused by microphthalmia (small eyes), anophthalmia (no eyes) and coloboma...

Characterizing the role of the endocannabinoid system’s catabolic enzymes FAAH and MAGL in the development of functional sensorimotor activities in zebrafish
DownloadFall 2022
The endocannabinoid system (eCS) plays a critical role in a variety of homeostatic and developmental processes. Generally, the eCS relies on the naturally produced compounds known as endocannabinoids (eCBs), which are lipophilic signaling molecules that interact with cannabinoid receptors to...

Differential expression of nicotinic acetylcholine receptor subunits is critical for the embryonic development of zebrafish muscle and neuromuscular junction
DownloadSpring 2020
Nicotinic acetylcholine receptors (nAChRs) are ligand gated ion channels primarily expressed on muscle fibers and neurons. They are comprised of five subunits arranged in different stoichiometries. nAChRs expressed at the neurons are comprised of different combinations of α1-10 and β1-4 subunits,...

Functional Characterization of Homeodomain Transcription Factors and Retinoic Acid Signaling in Hematopoiesis
DownloadSpring 2015
Improper regulation of hematopoiesis generates a spectrum of defects that range from anemia and embryonic lethality to leukemia. Identifying the molecular pathways that regulate hematopoiesis is therefore a major goal of both basic and clinical biology. Vertebrate hematopoiesis occurs in two...

Gene structure of the goldfish agouti-signaling protein: A putative role in the dorsal-ventral pigment pattern of fish
Download2005
Schioth, H.B., Haitina, T., Cerdá-Reverter, J.M., Peter, R.E.
One of the most successful chromatic adaptations in vertebrates is the dorsal-ventral pigment pattern in which the dorsal skin is darkly colored, whereas the ventrum is light. In fish, the latter pattern is achieved because a melanization inhibition factor inhibits melanoblast differentiation and...
