Novel Characterization Of The Role Of Orthologous Xap5 In Caenorhabditis Elegans, Nabor Vazquez
Novel Characterization Of The Role Of Orthologous Xap5 In Caenorhabditis Elegans, Nabor Vazquez
Lawrence University Honors Projects
Cilia are one of the oldest and most well conserved cellular organelles. Cilia provide an essential role in cellular locomotion, fluid regulation, and are a site for signal transduction pathways involved in sensation. A new study suggests that XAP5 is a transcription factor in a unicellular organism, Chlamydomonas reinhardtii, which regulates gene expression needed for proper cilium assembly. Our study investigates the conservation of the role of XAP5 in a multicellular system, Caenorhabditis elegans. Alignments between protein, coding region, and promoter sequences for XAP5 orthologs from related species show a good conservation in DNA and protein sequences. As part of …

Theses and Dissertations
The development of the nervous system is a multi-level, time-sensitive process that relies heavily on cell differentiation. However, the molecular mechanisms that control brain development remain poorly understood. We generated a knockout (KO) mouse for the cilia associated gene Spag17. These animals develop hydrocephalus and enlarged ventricles consistent with the role of Spag17 in the motility of ependymal cilia. However, other phenotypes that cannot be explained by this role were also present. Recently, a mutation in Spag17 has been associated with brain malformations and severe intellectual disability in humans. Therefore, we hypothesized that Spag17 plays a crucial role in …
