Fret Biosensors: Engineering Fluorescent Proteins As Biological Tools For Studying Parkinson’S Disease, Nathan J. Leroy, Jacob R. Norley, Saranya Radhakrishnan, Mathew Tantama Aug 2017

Fret Biosensors: Engineering Fluorescent Proteins As Biological Tools For Studying Parkinson’S Disease, Nathan J. Leroy, Jacob R. Norley, Saranya Radhakrishnan, Mathew Tantama

The Summer Undergraduate Research Fellowship (SURF) Symposium

Parkinson’s Disease (PD) is a common neurodegenerative disease with over 200,000 new cases each year. In general, the cause of the disease is unknown, but oxidative stress inside of neurons has been associated with the disease’s pathology for some time. Currently, techniques to study the onset of PD inside of neurons are limited. This makes treatments and causes difficult to discover. One solution to this has been fluorescent protein biosensors. In short, these proteins can be engineered to glow when a certain state is achieved inside a cell. The present research discusses the engineering of a genetically-encoded ...

Performing A Genetic Screen To Identify Factors That Promote Lncrna-Dependent Gene Repression, Chrishan Fernando, Cecilia Yiu, Sara Cloutier, Siwen Wang, Elizabeth Tran

The Summer Undergraduate Research Fellowship (SURF) Symposium

Long non-coding RNAs (lncRNAs) were once thought not to have useful functions in organisms but rather to be products of aberrant transcription. However, roles are being found for lncRNAs in beneficial processes such as controlling gene expression. In some of these cases, lncRNAs form R-loops in vivo. R-loops are nucleic acid structures consisting of hybridized strands of single-stranded DNA (ssDNA) and single-stranded RNA (ssRNA) as well as the displaced strand of ssDNA. Formation of these R-loops is important for gene regulation by the lncRNAs. However, factors that promote formation of lncRNA R-loops are not known. The gene PHO84 is being ...


Fluorescent Protein Biosensor For Use In Parkinson's Research, Piper R. Miller, Keelan Trull, Mathew Tantama Aug 2017

Fluorescent Protein Biosensor For Use In Parkinson's Research, Piper R. Miller, Keelan Trull, Mathew Tantama

The Summer Undergraduate Research Fellowship (SURF) Symposium

Purinergic signaling is a type of extracellular communication that occurs between cells, mediated by adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine. In Parkinson’s Disease, purinergic signaling is disrupted, which contributes to neurodegeneration. In order to monitor this change in cell-to-cell signaling, there is a need for the development of a fluorescent protein (FP) biosensor to study the changes in the concentration of the signaling molecule ATP and its decomposition bioproduct ADP. This summer a genetically encoded ADP sensor that measures changes in ADP concentration was developed. This sensor utilizes Forster Resonance Energy Transfer (FRET) which is a sensing ...

Streptococcus mutans JH1140 is a strain of bacteria which produces a lantibiotic product, named mutacin 1140. Mutacin 1140 has been shown to be effective at inhibiting Gram-positive bacterial infections caused by Staphylococcus aureus and Streptococcus pneumoniae. Mutacin 1140 is a ribosomally synthesized peptide antibiotic that undergoes extensive posttranslational modifications (PTM). We have found that Mutacin 1140 and an aminoglycoside, Kanamycin, when combined together, act synergistically against Staphylococcus aureus. This was determined by performing serial kill curve dilution overlays on solid media, followed up with kill curve by microdilution plate, and most recently confirmed with kill curve CFU count plates on ...

FSHD is linked to the misexpression of the DUX4 gene contained within the D4Z4 repeat array on chromosome 4. The gene encodes the DUX4 protein, a cytotoxic transcription factor that presumably causes the symptoms of the disease. However, individuals have been identified who express DUX4 in their muscle biopsies, but who remain asymptomatic, suggesting that there are other factors that modify FSHD penetrance or severity. We hypothesized that an FSHD-modifying factor would physically interact with DUX4, and we took a proteomic approach to identify DUX4-interacting proteins. We identified the multifunctional C1QBP protein as one such factor. C1QBP is known to ...

Celiac Disease is a hypersensitive response to gluten caused by HLA-DQ2 or HLA-DQ8 T-cell presentation, initiating destruction of intestinal epithelial cells. Currently, the only remedy for those suffering from celiac disease is elimination of all gluten from the diet. Studies indicate that an indigestible fragment of the gluten molecule, alpha-gliadin subcomponent 33-mer, rich in proline and glutamine, is responsible for the hypersensitivity response. Determination of 33-mer concentration in wheat lines could be beneficial to future development of wheat lines with reduced 33-mer concentration. Protein from wheat flour was extracted and subjected to ELISA techniques in order to quantify the concentration ...

Molecular Regulation Of Stem Cell Behavior During Tissue Repair And Cancer Formation, Nestor J. Oviedo Mar 2017

Molecular Regulation Of Stem Cell Behavior During Tissue Repair And Cancer Formation, Nestor J. Oviedo

Science Seminar Series

Oviedo will be presenting his work on identifying the mechanisms of adult stem cell fate determination based on their topographical location in the adult body. Understanding stem cell fate determination is crucial because tissue repair and neoplastic growth are greater in anterior than in posterior regions of adult animals. Despite its critical implications for stem cell biology, carcinogenesis and regenerative medicine, this physiological phenomenon has remained overlooked. Recent findings from his group provide intriguing evidence implying DNA repair mechanisms and cellular signaling through post-translational modifications regulate stem cell fate decision depending on their topographical location in the adult body. We ...
