Functional Characterization Of Rai1 In Zebrafish, Joshua S. Beach
Functional Characterization Of Rai1 In Zebrafish, Joshua S. Beach
Theses and Dissertations
Smith-Magenis Syndrome (SMS; OMIM #182290) is a multiple congenital abnormality and intellectual disability (ID) disorder caused by either an interstitial deletion of the 17p11.2 region containing the retinoic acid induced-1 (RAI1) gene or a mutation of the RAI1 gene. Individuals diagnosed with SMS typically present characteristics such as ID, self-injurious behavior, sleep disturbance, ocular and otolaryngological abnormalities, craniofacial and skeletal abnormalities, neurological and behavioral abnormalities, as well as other systemic defects and manifestations. Previous work by Vyas in 2009 showed temporal expression of rai1 in zebrafish embryos as early as 9 hpf. We hypothesize that there is maternal …
A Structure/Function Analysis Of Nhsl1b In Facial Branchiomotor Neurons, John Ojumu
A Structure/Function Analysis Of Nhsl1b In Facial Branchiomotor Neurons, John Ojumu
Theses and Dissertations
The goal of this study was to identify critical regions of a novel gene, Nance-Horan syndrome-like 1b (nhsl1b). It was previously discovered that C-terminal truncation of the Nhsl1b protein in nhsl1b mutants resulted in a loss of migration in the facial motor neurons of the hindbrain (Walsh et al. 2011). As nhsl1b expresses many isoforms, multiple targets were investigated in order to determine which transcript bears the largest impact on the motor neurons. Using confocal microscopy to observe immunostained embryos, we examined a mutation in an nhsl1b transcript that encodes a WHD, a domain that is known to …
