Temporal Resolution Of Cell Death Signaling Events Induced By Cold Atmospheric Plasma And Electroporation In Human Cancer Cells, Danielle M. Krug, Prasoon K. Diwakar, Ahmed Hassanein

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cancer treatment resistance and their invasive and expensive nature is propelling research towards developing alternate approaches to eradicate cancer in patients. Non-thermal, i.e., cold atmospheric plasma (CAP) and electroporation (EP) applied to the surface of cancerous tissue are new methods that are minimally invasive, safe, and selective. These approaches, both independently and synergistically, have been shown to deplete cancer cell populations, but the signaling mechanisms of death and their timelines of action are still widely unknown. To better understand the timeframe of signaling events occurring upon treatment, human cancer cell lines were treated with CAP, EP, and combined CAP with …

Genome-Scale Precision Proteomics Identifies Cancer Signaling Networks And Therapeutic Vulnerabilities, Hong Wang

Theses and Dissertations (ETD)

Mass spectrometry (MS) based-proteomics technology has been emerging as an indispensable tool for biomedical research. But the highly diverse physical and chemical properties of the protein building blocks and the dramatic human proteome complexity largely limited proteomic profiling depth. Moreover, there was a lack of high-throughput quantitative strategies that were both precise and parallel to in-depth proteomic techniques. To solve these grand challenges, a high resolution liquid chromatography (LC) system that coupled with an advanced mass spectrometer was developed to allow genome-scale human proteome identification. Using the combination of pre-MS peptide fractionation, MS2-based interference detection and post-MS computational interference correction, …

Ultrasound Monitoring Of Extant Adnexal Masses In The Era Of Type 1 And Type 2 Ovarian Cancers: Lessons Learned From Ovarian Cancer Screening Trials, Eleanor L. Ormsby, Edward J. Pavlik, John P. Mcgahan

Obstetrics and Gynecology Faculty Publications

Women that are positive for an ovarian abnormality in a clinical setting can have either a malignancy or a benign tumor with probability favoring the benign alternative. Accelerating the abnormality to surgery will result in a high number of unnecessary procedures that will place cost burdens on the individual and the health delivery system. Surveillance using serial ultrasonography is a reasonable alternative that can be used to discover if changes in the ovarian abnormality will occur that favor either a malignant or benign interpretation. Several ovarian cancer screening trials have had extensive experiences with changes in subclinical ovarian abnormalities in …

Ten Important Considerations For Ovarian Cancer Screening, Edward J. Pavlik

Obstetrics and Gynecology Faculty Publications

The unique intricacies of ovarian cancer screening and perspectives of different screening methods are presented as ten considerations that are examined. Included in these considerations are: (1) Deciding on the number of individuals to be screened; (2) Anticipating screening group reductions due to death; (3) Deciding on the duration and frequency of screening; (4) Deciding on an appropriate follow-up period after screening; (5) Deciding on time to surgery when malignancy is suspected; (6) Deciding on how screen-detected ovarian cancers are treated and by whom; (7) Deciding on how to treat the data of enrolled participants; (8) Deciding on the most …

Complications From Surgeries Related To Ovarian Cancer Screening, Lauren A. Baldwin, Edward J. Pavlik, Emma Ueland, Hannah E. Brown, Kelsey M. Ladd, Bin Huang, Christopher P. Desimone, John R. Van Nagell, Frederick R. Ueland, Rachel W. Miller

Obstetrics and Gynecology Faculty Publications

The aim of this study was to evaluate complications of surgical intervention for participants in the Kentucky Ovarian Cancer Screening Program and compare results to those of the Prostate, Lung, Colorectal and Ovarian Cancer Screening trial. A retrospective database review included 657 patients who underwent surgery for a positive screen in the Kentucky Ovarian Cancer Screening Program from 1988–2014. Data were abstracted from operative reports, discharge summaries, and office notes for 406 patients. Another 142 patients with incomplete records were interviewed by phone. Complete information was available for 548 patients. Complications were graded using the Clavien–Dindo (C–D) Classification of Surgical …

E2f Transcription Factor 1 And Its Role In The Cell Cycle And Tumor Suppressor Proteins, Thea Hisuler, Yu Kuang

AANAPISI Poster Presentations

E2F Transcription Factor 1 (E2F1) E2F1 is a transcription factor, in which its expression is increased in human cancers. “Transcription factor E2F1 binds to and activates transcription,” in return leading to increased transcription at the G1 and S phase of the cell cycle (Slansky). The E2F transcription factor family “plays a crucial role in the control of cell cycle and action of tumor suppressor proteins and is also a target of the transforming proteins of small DNA tumor viruses” (NCBI).

The Effect Of K562-Il21-2 Plasma Membrane Particles On The Proliferation Of Natural Killer Cells To Fight Cancer, Michelle Prophete

Honors Undergraduate Theses

Immunotherapy has emerged as a current and future paradigm of cancer treatment, which utilizes the body’s immune system to eradicate cancer. Natural Killer (NK) cells as part of the innate immune system have immense potential in their anti-tumor cytotoxic activities and host cell surveillance properties. NK cells comprise approximately five to fifteen percent of peripheral blood lymphocytes and can be proliferated in vitro using recently developed methods with co-cultures with feeder cells (derived from engineered tumor cells) or plasma membrane (PM) particles, produced from the fore mentioned feeder cells, in combination with soluble cytokines. For efficient growth and maintenance of …

Fluorescent Probe Development For Fructose Specific Transporters In Cancer, Joseph Fedie

Dissertations, Master's Theses and Master's Reports

Carbohydrate transporters or GLUTs of the major facilitator superfamily (MFS) are responsible for transporting sugars into the cell and have been of research interest for decades. Disruptions, mutations, and over-activations of GLUTs have been linked to a number of major diseases including cancer, obesity, and diabetes. Differentiating between transporters is incredibly difficult due to highly conserved structures, and so specific targeting between transporters has proven a complex challenge. GLUTs are highly flexible in their conformations however exactly what will and will not pass through the transporter is ambiguous at best, and many attempt to target these transporters have failed.
