Overexpression Of Foxf2 In Prostate Cancer Cells Causes An Increase In Cancer Cell Apoptosis And A Decrease In Proliferation, Vaughn Poon
Honors Projects
FOXF2 is a transcription factor that plays a crucial role in organ development, and recent studies have shown that it suppresses tumor growth and progression in mouse prostate models by attenuating the cancer-associated fibroblasts (CAF) phenotype and transcriptionally downregulating Cxcl5. However, the effects of FOXF2 overexpression in prostate cancer cells have not been extensively studied. Here, we investigate the impact of FOXF2 overexpression in prostate cancer cells and demonstrate that it leads to a significant increase in cell apoptosis and a decrease in proliferation. These findings suggest that FOXF2 may have potential as an immunotherapy drug target for prostate …

Bci Validation: Yfiler Plus Kit Validation, Chloe Koon
Honors Projects
In order to have access and use the Combined DNA Index System (CODIS), it is required by the Federal Bureau of Investigation's Quality Assurance Standards (FBI-QAS) for Forensic DNA Units to complete comprehensive validation studies on all equipment, materials, and methods used in the process of DNA analysis. This study continues validation previous done within the Ohio Bureau of Criminal Investigation (BCI). YFiler Plus is a DNA amplification kit that is used in cases where it is most useful to examine only male DNA profile(s) within a sample by amplifying loci only on the Y-Chromosome. Components of this study include …
Genetic Analysis Of Adhesion Protein Elmo3 In Arabidopsis Thaliana, Garrison Asper
Genetic Analysis Of Adhesion Protein Elmo3 In Arabidopsis Thaliana, Garrison Asper
Honors Projects
The Extracellular Matrix (ECM) between plant cells is vital for structure, development, and intercellular adhesion. A pectin rich layer in between cells, the middle lamella, is largely responsible for regulating the adhesive properties of adjacent plant cells. Homogalacturonan (HG) pectin, the most common, is synthesized in the Golgi and secreted into the ECM where it undergoes calcium crosslinking, increasing its adhesive properties. Mutations in proteins essential for HG synthesis can reveal a severe adhesion defective phenotype, where the hypocotyls of dark grown Arabidopsis exhibit cell sloughing, curling, and general disorganization. A family of five ELMO proteins are suspected to act …
Examining The Role Of Grp And Lik1 In Wall Associated Kinase (Wak) Perception Of Pectin In The Plant Cell Wall, Jack Ryan Mitchell
Examining The Role Of Grp And Lik1 In Wall Associated Kinase (Wak) Perception Of Pectin In The Plant Cell Wall, Jack Ryan Mitchell
Honors Projects
Wall associated kinases (WAKs) are cell membrane bound receptor kinases that bind pectin and pectin fragments (OGs).The binding of WAKs to pectin sends a growth signal required for cell elongation and plant development. WAKs bind OGs with higher affinity than native pectin and instead activate a stress response. Glycine rich proteins (GRPs) are secreted cell wall proteins of unknown function. Seven GRPs with 65% sequence similarity are coded on a 90kb locus of Arabidopsis chromosome 2. GRP3 and WAK1 have been shown to bind in vitro, but single null mutations have no discernible phenotype, suggesting that the GRPs are redundant. …
Purification Of A Bacteriophage Protein Involved In Host Range Specificity, Alec Brown
Purification Of A Bacteriophage Protein Involved In Host Range Specificity, Alec Brown
Honors Projects
The Escherichia coli ferric hydroxamate uptake receptor FhuA serves as the receptor for ferrichrome-Fe(III) complexes, with TonB protein energizing the active transport of the complex. The FhuA receptor is exploited by a variety of bacteriophages as a conduit into the cell. Interestingly, certain of these phages carry a gene called “Cor”, the product of which, when cloned and expressed from a plasmid, blocks transport by FhuA. In the present study, components of the cor gene from the bacteriophage ϕ80 were used to construct an IPTG-inducible MalE-Cor-His6 fusion protein, which allowed for affinity purification of the Cor protein. At 61 residues …

The oomycete Phytophthora parasitica has a worldwide distribution and is an economically important pathogen of more than 100 species4. RNA-seq analysis showed that one gene, PPTG_16698 has the 5th highest level of expression of all transport proteins in the zoospore stage, and is highly conserved throughout Phytophthora species. This project attempts to characterize the important biological role that PPTG_16698 plays in P. parasitica and other oomycetes. Three strategies have been implemented to accomplish this goal: growth analysis by heterologous expression in yeast, metabolite analysis in yeast, and construction of a GFP fusion protein to enable localization of …
