Testing Ssa4:Ade3 Reporters For Mcs Screening, Karah Edmonds, Rebecca Adams
Science University Research Symposium (SURS)
In eukaryotic cells, after transcription, mRNA is escorted from the nucleus to the cytoplasm to be translated. This process, called mRNA export, is essential for gene expression. However, when the cell exists in stressful conditions, mRNA export becomes regulated, and only select transcripts, including the stress-responsive SSA4 mRNA, can be exported. This project aims to uncover the mechanism of selective SSA4 mRNA export by generating a reporter that enables phenotypically visible expression under stressful conditions. Specifically, the ADE3 ORF was placed under the regulatory sequence of SSA4, which was anticipated to induce a red color for colonies only following stress. …
An Analysis Of Crispr-Cas Gene Editing In Agriculture, Ashley Laliberte
An Analysis Of Crispr-Cas Gene Editing In Agriculture, Ashley Laliberte
Honors Scholar Theses
The CRISPR-Cas system is a promising form of gene editing, especially for the agriculture industry. The ability to make single-nucleotide edits within a gene of interest, without the need to introduce foreign DNA, is a powerful tool for designing healthier and more efficient crops and food animals. This system provides opportunity for increased nutritional value, decreased food waste, and more economically and environmentally sustainable food production. Though this biotechnology is facing mechanistic limitations due to off-target effects and inefficient homology-directed repair, vast improvements have already been made to improve its efficacy. The CRISPR-Cas system is already the most advanced form …

Phosphatase of Regenerating Liver (PRL) proteins regulate a number of important cellular processes, including cell growth and division. Humans have three PRL proteins: PRL-1, PRL-2, and PRL-3. An accumulation of evidence has shown that elevated levels of PRLs are strongly correlated with uncontrollable growth and metastasis of tumors. However, contradictory findings have arisen indicating that PRLs instead function to halt cell division thereby preventing uncontrollable tumor growth. In light of these results, the underlying mechanisms regarding how PRLs function within cellular processes remains unclear. To investigate the functions of PRLs, we will create transgenic fruit flies (Drosophila melanogaster) …
