Engineering Bioluminescent Sensors Of Cyclic Amp To Study Opioid Signaling, Alexander L. Tesmer, Alexander R. French, Mathew Tantama
The Summer Undergraduate Research Fellowship (SURF) Symposium
Opioids are small signaling molecules which bind to opioid receptors on the surface of cells. The kappa opioid receptor (KOR) is one of three major types of opioid receptors found in human neurons. When an opioid binds to a KOR, a variety of biochemical signaling pathways are activated inside the cell. Each of these pathways are associated with different physiological effects of KOR activation. The production of a small signaling molecule, cyclic adenosine monophosphate (cAMP), is known to be inhibited during KOR activation of the analgesic (pain-killing) signaling pathway. The ability to interrogate the individual responses of KOR signaling pathways …
Cost-Effective Paper-Based Diagnostic Using Split Proteins To Detect Yeast Infections, Zachary R. Berglund, Kevin V. Solomon, Mohit S. Verma, Moiz Rasheed, Zachary Hartley, Kevin Fitzgerald, Kok Zhi Lee, Janice Chan, Julianne Dejoie, Makayla Schacht, Alex Zavala

The common yeast infection, vulvovaginal candidiasis, affects three out of four women throughout their lifetime and can be spread to their child in the form of oral candidiasis (thrush). This disease is caused by the fungal pathogen Candida albicans, which is also a major cause of systemic candidiasis, a rarer but deadly disease with up to a 49% lethality rate. Current widely-used diagnostic methods include cell cultures, pH tests, and antibody detection, to assist effective treatment. Despite availability of various diagnostic methods, there is no inexpensive, rapid, and accurate way to detect C. albicans infection. This project aims to …
Targeted Epigenetic Editing Using Optogenetic Tools, Joshua Hahn, Chongli Yuan
Targeted Epigenetic Editing Using Optogenetic Tools, Joshua Hahn, Chongli Yuan
The Summer Undergraduate Research Fellowship (SURF) Symposium
Epigenetics markers, such as DNA methylation and histone post-translational modifications, are modifications to the structure of DNA that impact gene expression without altering the genetic code. Among them, DNA methylation plays a critical role in various biological processes including the differentiation of stem cells, regulation of gene expression, and adaptation to environmental signals. The ability to modify DNA methylation at particular genes in various cell types is thus desirable for engineering specific cell phenotypes. Although technologies exist that can alter DNA methylation at target genes, these techniques lack spatial and temporal resolution and are not able to selectively edit individual …
Genome Analysis Of Multiple Mycobacteriophage, Emily Kerstiens, Kari Clase, Yi Li, Gillian Smith, Sarah Bell
Genome Analysis Of Multiple Mycobacteriophage, Emily Kerstiens, Kari Clase, Yi Li, Gillian Smith, Sarah Bell
The Summer Undergraduate Research Fellowship (SURF) Symposium
Bacteriophage are viruses that infect and kill bacteria. They can be used as treatments for antibiotic resistant bacterial infections, but more knowledge is needed about phage and how they interact with bacteria in order to develop safe and effective phage therapy treatments. This study examines the genomes of eighteen mycobacteriophage that were isolated from the environment on and surrounding Purdue University. Phage genomes were annotated using several bioinformatics software, including DNA Master, GeneMark, and PECAAN. Evidence was examined to determine the correct location within the genome and the potential function. Approximately two thousand genes were annotated in this study. A …
Targeting Neuropeptides To Bone Fractures For Accelerated Healing, Nicholas A. Young, Jeffery J. Nielsen, Philip S. Low
Targeting Neuropeptides To Bone Fractures For Accelerated Healing, Nicholas A. Young, Jeffery J. Nielsen, Philip S. Low
The Summer Undergraduate Research Fellowship (SURF) Symposium
In patients over the age of 65 especially, bone fractures represent a significant disease burden. Non-invasive drug therapies are not available for bone fractures which represents a problem for this population. Vasoactive intestinal peptide (VIP) and Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP), two neuromodulator peptides in the glucagon superfamily, have demonstrated positive regulation of osteoblast proliferation and activity. Using acidic oligopeptides, we have developed ligands that target to and accumulate at fracture sites. These targeting ligands can be synthesized in sequence with bone anabolic peptides to minimize off target effects and increase potency at the fracture site to create safer and …
Investigation On The Effect Of Pasteurisation On The Bacteria Contamination Of Eggs, Alya Sufiyah Bte Mohamed Subhan
Investigation On The Effect Of Pasteurisation On The Bacteria Contamination Of Eggs, Alya Sufiyah Bte Mohamed Subhan
The International Student Science Fair 2018
This project is a research on bacteria contamination on pasteurised and non-pasteurised eggs. In Singapore, there has been an increase in salmonella cases since 2016. Recently in the US, more than 206 million eggs in supermarkets and grocery chains had to be recalled. This project will explain about the different in bacterial colonies found on seemingly similar eggs.
The Use Of Potato (Solanum Tuberosum) Suspension Cells For Rapid Screening Of Chloroplast Transformation Vectors, Lindsey Shover
The Use Of Potato (Solanum Tuberosum) Suspension Cells For Rapid Screening Of Chloroplast Transformation Vectors, Lindsey Shover
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Chloroplast genetic engineering is unique in that it allows for high levels of gene expression while providing a means of natural bio-confinement. Although the chloroplast genome sequence of over 800 plant species is known, the elements that naturally regulate chloroplast gene expression are poorly understood. Recently, our lab has developed a 264 part modular cloning kit that contains known chloroplast regulatory elements. This kit can be used for the construction of novel chloroplast transformation cassettes; however, functional testing of these cassettes is currently hindered by standard chloroplast transformation technologies. Therefore, the aim of this experiment was to develop a rapid …
