Characterization Of Genes In The Cftr-Mediated Innate Immune Response, Eric Peterman

Honors College

Recently, the Kim Lab has shown that the cystic fibrosis transmembrane conductance regulator (cftr) gene is responsible for mediating resistance to Pseudomonas aeruginosa in a zebrafish infection model. Using the Gene Expression Omnibus, an NCBI functional genomics data repository, it was determined that Smad3, a transcription factor in the TGF-β signaling pathway, is upregulated in the presence of P. aeruginosa. It was found that in our zebrafish model, the Smad3 paralogs Smad3a and Smad3b are upregulated following microinjection of a cftr antisense morpholino oligomer. It was also found that microinjection of Smad3a and Smad3b morpholinos, along with …
