Undergraduate Theses, Professional Papers, and Capstone Artifacts
The receptor tyrosine kinases (RTKs) are known to help regulate cell behaviors including differentiation, proliferation and migration during embryonic development of the neural crest. RTKs are believed to initiate signaling cascades in response to extracellular cues in part by controlling localization of Src-family kinases (SFKs). The scaffolding protein PAG1 binds SFKs and is believed to influence SFK activity and location within the cell by promoting interaction of SFKs with regulatory proteins and by drawing SFKs into different components of the endocytic pathway. By targeting the PAG1 gene in SH-SY5Y neuroblastoma cells with CRISPR/Cas9 plasmids, we created PAG1-mutant cell-lines in which …

A degenerative disease-like phenotype, specifically reduction in synaptic protein levels in adult worms, is correlated with loss-of-function of the only RFX transcription factor gene, daf-19, in C. elegans. This gene encodes four known transcription factor isoforms, two of which are correlated with particular functions. The DAF-19C isoform activates genes responsible for cilia development, while DAF-19M is needed for cilia specification in males. A comparison of the transcriptome of daf-19 null and isogenic wild type adult worms suggests both positive and negative regulation of gene expression is correlated with the presence of DAF-19 proteins. We have assessed DAF-19 regulation …
