Trick to the Treat of Internships and Research
This program is a 10-week internship designed for undergraduates interested in the scientific field to engage in current research. Students have the option of requesting to work under three mentors, one of which they will be paired. Students will work in the lab with the principal investigator and other members of the lab. Along with working in the lab, students in the program will also attend bi-weekly talks/lectures from researchers, grad students, and professionals at TSRI as well as participating in two presentations and a final poster or oral presentation.

Brain homeostasis can be affected in a number of ways that lead to gross anatomical, cellular, and molecular disturbances giving rise to diseases like Alzheimer’s disease (AD) and related dementias. Unfortunately, the mechanistic pathoetiology of AD’s hallmark features of cerebral amyloid plaque buildup and neuronal death are still disputed. Using human brain AD sections, immunohistochemistry experiments revealed internalized surface proteins, co-localized to an expanded lysosomal compartment. Other stains for amyloid-β1-42 (Aβ42) and various immunoglobulin (Ig) species displayed them leaking out of the cerebrovasculature through a dysfunctional blood-brain barrier (BBB), binding to neurons in the vicinity, and localizing to intracellular vesicles …
Regulation Of Breast Cancer Initiation And Progression By 14-3-3zeta, Chia-Chi Chang
Regulation Of Breast Cancer Initiation And Progression By 14-3-3zeta, Chia-Chi Chang
Dissertations & Theses (Open Access)
14-3-3ζ is a ubiquitously expressed family member of proteins that have been implicated to have oncogenic potential through its interactions and involvement in cancer initiation and progression. 14-3-3ζ belongs to the highly conserved 14-3-3ζ protein family and modulates numerous pathways in cancer. Overexpression of 14-3-3ζ is an early event, occurs in more than 40% of human breast cancer cases, and is associated with disease recurrence and poor prognosis. Metabolic reprogramming is a hallmark of cancer. Cancer cells elevate aerobic glycolysis to produce metabolic intermediates and reducing equivalents, thereby facilitating cellular adaptation to the adverse environment and sustaining fast proliferation. Interestingly, …

DAF-19, the only RFX transcription factor found in C. elegans, is required for the formation of neuronal sensory cilia. Four isoforms of the DAF-19 protein have been reported, and the m86 nonsense (null) mutation affecting all four isoforms has been shown to prevent cilia formation. Transcriptome analyses employing microarrays of L1 and adult stage worms were completed using RNA from daf-19(m86) worms and an isogenic wild type strain to identify additional putative DAF-19 target genes. Using transcriptional fusions with GFP, we compared the expression patterns of several potential gene targets using fluorescence confocal microscopy. Expression patterns were characterized in …

Senior Theses and Projects
A growing body of research suggests that dopaminergic cell death seen in Parkinson’s disease is caused by mitochondrial dysfunction. Oxidative stress, with subsequent generation of reactive oxygen species, is the hallmark biochemical product of mitochondrial dysfunction. The ketogenic diet has been found to enhance mitochondrial energy production, protect against reactive oxygen species-generated cell death, and increase adenosine, a purine that modulates dopamine activity. The current study evaluates the effects of a long-term (5-month) ketogenic diet on behavioral, neurochemical, and neuroanatomical measures in PINK1-KO rats, a new animal model of Parkinson’s disease. Both wild-type and PINK1-KO animals fed a ketogenic diet …

We have frequently implemented crossover studies to evaluate new therapeutic interventions for genital herpes simplex virus infection. The outcome measured to assess the efficacy of interventions on herpes disease severity is the viral shedding rate, defined as the frequency of detection of HSV on the genital skin and mucosa. We performed a simulation study to ascertain whether our standard model, which we have used previously, was appropriately considering all the necessary features of the shedding data to provide correct inference. We simulated shedding data under our standard, validated assumptions and assessed the ability of 5 different models to reproduce the …

In order for a cancer cell to thrive, it must alter its metabolism to produce the energy needed for rapid growth. Cells accomplish this by the Warburg Effect, or switching metabolism to aerobic glycolysis, where a cell can rapidly break down sugar into ATP, lactic acid and additional byproducts. Hexokinase 2, the enzyme that catalyzes the first committed step of glycolysis, may also be upregulated in cancer cells to increase glucose breakdown. Similar proteins for metabolism are found in both S. cerevisiae and mammalian cells. S. cerevisiae regulates metabolism through glucose repression, by Snf1 (mammalian homolog: AMPK) activation, which aids …
