Stability Of Eukaryotic Elongation Factor One Alpha Protein In The Cell, Jennifer Watry Apr 2007

Stability Of Eukaryotic Elongation Factor One Alpha Protein In The Cell, Jennifer Watry

Honors Theses

Eukaryotic Elongation Factor One Alpha (eEF1A) is an abundant protein found in every cell of every organism and is involved in functions concerning protein synthesis and degradation, the cytoskeleton, and signaling. How these functions are regulated is not yet understood for this protein. Regulation of the protein may be controlled by transcription of the genes encoding the protein or the stability and modification of the protein. The goal of this project was to determine the stability of eEf1A proteins in Arabidopsis thaliana. Protein stability was determined by treating tissues with cycloheximide, an inhibitor of protein synthesis. Gel electrophoresis and …

Development Of Proliferation Assays To Explore The Role Of Calcium Activated Potassium Channels In Cell Proliferation, Sean Foster Jan 2006

Development Of Proliferation Assays To Explore The Role Of Calcium Activated Potassium Channels In Cell Proliferation, Sean Foster

Honors Theses

Due to the large variety of K† channel families implicated in cancer cell proliferation, it is desirable to develop techniques capable of quickly and reliably screening a variety of potential channels for a role in proliferation. While there are many established cell counting procedures, the time-consuming nature of such protocols limits their usefulness in broadly identifying particular channels in uncharacterized cell lines. For this reason, a primary goal of the present research was the development of techniques capable of implicating particular ion channels in proliferation with both qualitative and quantitative data. Once this goal was accomplished, the project sought …

Oral Cancer Screening, Damon Omar Watson Jun 1997

Oral Cancer Screening, Damon Omar Watson

Honors Theses

Cancers of the oral cavity and pharynx have increased throughout the decades. Since oral cancer represents a small percentage of the total cancers in the United States, it is often overlooked. Though this is the case, the results of this cancer can be devastating. To address this issue, an Oral Cancer Screening was organized on August 14, 1996 at the West Michigan Cancer Center in Kalamazoo. This was a joint collaboration between the author, the West Michigan Cancer Center, and the Kalamazoo Valley Dental Society. This event allowed research to take place concerning the data obtained. Confidential results and information …

A Quantitative Study Of The Distinctive Proteins Of The Eosinophil: A Comparison Of Normals And Eosinophilic Patients, James M. Olson Dec 1984

A Quantitative Study Of The Distinctive Proteins Of The Eosinophil: A Comparison Of Normals And Eosinophilic Patients, James M. Olson

Honors Theses

Eosinophils have long been associated with parasitic and allergic diseases. Methods of procurement and purification of eosinophils in the last ten years have allowed intensive investigation into their components, properties, functions, and mechanisms (Gleich et al, 1982). The goals of this project are to separate eosinophils in blood samples taken from patients with eosinophilia and from normals based on density over distontinuous Metrizamide gradients; to determine quantitatively the levels of the three distinctive proteins of the eosinophil, specifically MBP, EDN, and ECP; and to compare the levels of these proteins found in eosinophils of patients with eosinophilia to the amounts …

A Comparative Consideration Of Lipoprotein Distribution And Stress Response In The Mallard Duck And Man, Janice Mackay Apr 1972

A Comparative Consideration Of Lipoprotein Distribution And Stress Response In The Mallard Duck And Man, Janice Mackay

Honors Theses

Lipid is associated with all of the major serum protein fractions of both the mallard duck and man. however, whereas the ρ lipoproteins predominate in man with little lipo-albumin evident, according to available literature, in ducks the lipo-albumin constitutes more than half of the serum lipoproteins, and a substantial lipo-prealbumin fraction is evident. Most studies of lipo-proteins are carried out on human serum primarily for the purpose of diagnosis of abnormalities. The stress response in many animals includes a rise in serum α-globulin levels, but its physiological basis is still speculative. While a consideration of the changes in lipoprotein distribution …

The Effects Of Moist-Heat Treatments And Stratification On Germination Of Prairie Plant Seeds, John E. Stuurwold Apr 1972

The Effects Of Moist-Heat Treatments And Stratification On Germination Of Prairie Plant Seeds, John E. Stuurwold

Honors Theses

Germination of Silphium terebinthenaceum was enhanced by a post-stratification most-heat treatment at 80°C. Tested seeds of four other perennial herbs common to midwestern prairies (Andropogon scoparius, Sorghastrum nutans, Eryngium yuccifolium, and Solidago rigida) showed little adverse or beneficial effects of the heat treatment. Heat treatments alone had little effect on the seeds; the length of stratification periods necessary to effect maximal germination varied. The significance of these findings is examined in the light of related literature on grassland fire ecology.

The Role Of D-Gluconic Acid In The Regulation Of The Synthesis Of The Enzymes Of The Entner-Doudoroff Pathway In Pseudomonas Fluorescens, Steven C. Quay Aug 1971

The Role Of D-Gluconic Acid In The Regulation Of The Synthesis Of The Enzymes Of The Entner-Doudoroff Pathway In Pseudomonas Fluorescens, Steven C. Quay

Honors Theses

Induction of Entner-Duodoroff pathway enzymes in Pseudomonas fluorescens was investigated to study the role of gluconate as a possible inducer. Glucose oxidase-deficient mutants were isolated and characterized. One of these mutants, gox-7, was deficient in particulate glucose oxidase; another mutant, gox-17, was deficient in particulate glucose and gluconate oxidase activities. Gluconate, but not glucose, induced synthesis of gluconokinase and 6-phosphogluconate dehydratase in both mutants. High constitute levels of 2-keto-3-deoxy-6-phosphogluconate aldolase were found when both mutants were grown on glucose. Growth of parent and both mutant strains on glycerol also resulted in high levels of Entner-Doudoroff pathway enzymes. It was concluded …
