Introduction To Nanoscopy Nano-Talk, George Mcnamara

George McNamara

T7-1 is the designation for the LMRG Nanoscopy session at ABRF in Orlando, FL, on March 20, 2012. The PDF file here is a draft of my presentation.

May not be very helpful since (1) would probably help to know what is in my head and each slide will [hopefully] prompt me to say, and (2) 10 minute talk so I am going to push the "next slide" button after saying very little.

Pubspectra - Open Data Access Fluorescence Spectra, George Mcnamara

George McNamara

The Internet is enabling greater access to spectral imaging publications, spectral graphs, and data than that was available a generation ago. The spectral imaging systems discussed in this issue of Cytometry work because reagent and hardware spectra are reproducible, reusable, and provide input to spectral unmixing and spectral components recognition algorithms. These spectra need to be readily available in order to determine what to purchase, how to use it, and what the output means. We refer to several commercially sponsored and academic spectral web sites and discuss our spectral graphing and data sites. Sites include fluorescent dye graph servers from …

Investigating The Mechanism Of Nur77-Induced Apoptosis In T Cells, Heather E. Fogarty

Masters Theses 1911 - February 2014

Nur77 is a member of the orphan nuclear receptor family, where it is known to play an important role in apoptosis in both negative selection in T cells and in cancer cell lines. In the development of T cells, it is critical for the immune system to discriminate self from non-self by eliminating auto-reactive cells. It was originally thought that Nur77 initiated apoptosis by activating downstream gene targets. However, it is now clear that Nur77 has its own distinct role outside of the nucleus and the precise mechanisms by which Nur77 induces apoptosis in T cells still needs to be …

Notch Regulation Of Adam12 Expression In Glioblastoma Multiforme, Ala'a S. Alsyaideh

Masters Theses 1911 - February 2014

Glioblastoma is the most common malignant brain tumor, accounting for 17% of all primary brain tumors in the United States. Despite the available surgical, radiation, and chemical therapeutic options, the invasive and infiltrative nature of the tumor render current treatment options minimally effective. Recent reports have identified multiple regulators of glioblastoma progression and invasiveness. It has been demonstrated that ADAM12, A Disintegrin And Metalloproteinase encoded by ADAM12 gene, is over-expressed in glioblastoma and directly correlated with tumor proliferation. Additionally, dysregulation of the Notch signaling pathway has been implicated in the pathogenesis of many gliomas. Lastly, an evolving role of microRNAs, …

The Effects Of Cancer, Mara Lapayne

A with Honors Projects

I chose to do a project related to cancer for my Painting 1 class. Using oil paint, I wanted to create a more symbolic representation of cancer. So I made a cloud-like, cancerous mass with streaks of chaotic color swirling around a central face. The face represents any person affected by cancer and has had to “shut down” their emotions in order to function. I wanted the skin texture to be almost metallic as if it is metal armor or robotic-like, to support the idea of “shutting down” one’s emotions. The blank expression also portrays this idea.

This project focuses on the common long term side effects of cancer treatments, apart from cure. In addition to physiological function changes, it focuses on the chemical composition of chemotherapy drugs.

Integrative Bayesian Analysis Of High-Dimensional Multi-Platform Genomics Data, Wenting Wang, Veerabhadran Baladandayuthapani, Jeffrey S. Morris, Bradley M. Broom, Ganiraju C. Manyam, Kim-Anh Do

Jeffrey S. Morris

Motivation: Analyzing data from multi-platform genomics experiments combined with patients’ clinical outcomes helps us understand the complex biological processes that characterize a disease, as well as how these processes relate to the development of the disease. Current integration approaches that treat the data are limited in that they do not consider the fundamental biological relationships that exist among the data from platforms.

Statistical Model: We propose an integrative Bayesian analysis of genomics data (iBAG) framework for identifying important genes/biomarkers that are associated with clinical outcome. This framework uses a hierarchical modeling technique to combine the data obtained from multiple platforms …

1 '- Acetoxychavicol Acetate Inhibits Growth Of Human Oral Carcinoma Xenograft In Mice And Potentiates Cisplatin Effect Via Proinflammatory Microenvironment Alterations, Noor Hasima Nagoor

Noor Hasima Nagoor

Background: Oral cancers although preventable, possess a low five-year survival rate which has remained unchanged over the past three decades. In an attempt to find a more safe, affordable and effective treatment option, we describe here the use of 1'S-1'-acetoxychavicol acetate (ACA), a component of Malaysian ginger traditionally used for various medicinal purposes. Methods: Whether ACA can inhibit the growth of oral squamous cell carcinoma (SCC) cells alone or in combination with cisplatin (CDDP), was explored both in vitro using MTT assays and in vivo using Nu/Nu mice. Occurrence of apoptosis was assessed using PARP and DNA fragmentation assays, while …

Cdk1 And Plk1 Mediate A Clasp2 Phospho-Switch That Stabilizes Kinetochore–Microtubule Attachments, Ana R. R. Maia, Zaira Garcia, Lilian Kabeche, Marin Barisic

Dartmouth Scholarship

Accurate chromosome segregation during mitosis relies on a dynamic kinetochore (KT)-microtubule (MT) interface that switches from a labile to a stable condition in response to correct MT attachments. This transition is essential to satisfy the spindle-assembly checkpoint (SAC) and couple MT-generated force with chromosome movements, but the underlying regulatory mechanism remains unclear. In this study, we show that during mitosis the MT- and KT-associated protein CLASP2 is progressively and distinctively phosphorylated by Cdk1 and Plk1 kinases, concomitant with the establishment of KT-MT attachments. CLASP2 S1234 was phosphorylated by Cdk1, which primed CLASP2 for association with Plk1. Plk1 recruitment to KTs …

Targeting The Cancer Cell Cycle By Cold Atmospheric Plasma, Olga Volotskova, Teresa S. Hawley, Mary Ann Stepp, Michael Keidar

Anatomy and Regenerative Biology Faculty Publications

Cold atmospheric plasma (CAP), a technology based on quasi-neutral ionized gas at low temperatures, is currently being evaluated as a new highly selective alternative addition to existing cancer therapies. Here, we present a first attempt to identify the mechanism of CAP action. CAP induced a robust ~2-fold G2/M increase in two different types of cancer cells with different degrees of tumorigenicity. We hypothesize that the increased sensitivity of cancer cells to CAP treatment is caused by differences in the distribution of cancer cells and normal cells within the cell cycle. The expression of γH2A.X (pSer139), an oxidative stress reporter indicating …

Prl-1’S Inhibition Of Drosophila Melanogaster Cell Growth Is Dependent On The Caax Membrane Localization Domain, Bryce Bunn

Summer Research

The human body exhibits a spectacular collection of cells, integrated with seemingly infinite communication techniques and control mechanisms. Cancer’s disastrous influence on this complex system proves difficult to map. The shotgun clinical trial testing of human cancers has provided a feast of proteins suspected of encouraging cancerous cell behavior. One, Phosphatase of Regenerating Liver protein-1 (PRL-1), has been found to encourage cancerous growth while localizing in a variety of subcellular locations within metastasizing human tumor cells. However, PRL-1 has also been found to act as a tumor suppressor while localizing to the cell membrane in mammalian and insect models. In …

Nanosecond pulsed electric fields (nsPEF) induce apoptotic pathways in human cancer cells. The potential therapeutic effective of nsPEF has been reported in cell lines and in xenograft animal tumor model. The present study investigated the ability of nsPEF to cause cancer cell death in vivo using carcinogen-induced animal tumor model, and the pulse duration of nsPEF was only 7 and 14 nano second (ns). An nsPEF generator as a prototype medical device was used in our studies, which is capable of delivering 7-30 nanosecond pulses at various programmable amplitudes and frequencies. Seven cutaneous squamous cell carcinoma cell lines and five …

Effect Of Chlorogenic Acid And Neochlorogenic Acid On Human Colon Cancer Cells, Taylor Thurow, Sun-Ok Lee

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Prune consumption has been associated with a decreased risk of colon cancer; yet there has been confusion as to which chemical component(s) of the prune are responsible for its anticarcinogenic properties. Previous studies have evaluated chlorogenic acid as a chemotherapeutic agent; however, only a limited amount of studies have investigated neochlorogenic acid, the predominant phenolic compound found in the prune. The purpose of this study was to determine the effects that chlorogenic acid and neochlorogenic acid have as anticarcinogenics on the human adenocarcinoma, Caco-2 cell line. The anti-colon cancer effects of chlorogenic acid and neochlorogenic acid were analyzed by experiments …

Analysis Of Human Tacc3 In Cellular Responses To Polycyclic Aromatic Hydrocarbons, Ivan H. Still, B. Lauffart

Journal of the Arkansas Academy of Science

Very little is known about the etiology of ovarian cancer. However, studies have shown that occupational exposure to polycyclic aromatic hydrocarbons (PAHs) and tobacco smoking can increase ovarian cancer risk. Previously, we have determined that 100% of ovarian tumors show loss or aberrant subcellular localization of TACC3 (transforming acidic coiled coil 3) relative to the normal ovarian surface epithelium (OSE). In mice, a role for TACC3 in the cellular response to PAH has been defined. However, comparable studies for human TACC3 has not been performed. In this report, we show that specific knockdown of TACC3 in human ovarian cancer cells …
