A Study Of Genetic Variation In Geographically Separated Populations Of Pediomelum Pariense, Asher Jones, Dr. Keith A. Crandall
A Study Of Genetic Variation In Geographically Separated Populations Of Pediomelum Pariense, Asher Jones, Dr. Keith A. Crandall
Journal of Undergraduate Research
Pediomelum pariense, also known as Paria River Indian Breadroot, has been listed by NatureServe as an imperiled organism because of its low population numbers. However, no state or federal agency has made any effort to promote the preservation of this species. Ashley Egan, PhD, designed a study with the purpose of changing that. Through the use of methods designed to measure genetic diversity, I was able to assist Dr. Egan in discovering if the amount of genetic variation that exists among the remaining P. pariense populations should be a cause of government concern.

Organizing Byu’S Fungi Collection, Tess Blackwelder, Dr. Leigh Johnson
Journal of Undergraduate Research
The Monte L. Bean Life Science Museum at Brigham Young University houses many biological collections for study and display. Among the collections of insects, plants, fish, and mammals, there is also a fungi collection. This was donated to BYU by mycologist Kent McKnight (former BYU faculty) several years ago upon his death. Unfortunately, this collection had been rather neglected; it was neither organized, documented, nor accessible to others, and a complete inventory of the scope of the collection did not exist. My ORCA grant idea was to sort through the collection, set up an effective system of organization, create a …

Crustaceans are some of the richest multi-cellular animals in the world in terms of species. Within the crustaceans the decapods are chief in species numbers and diversity with over 15,000. Among these are the very familiar and well-known species, such as crayfish, shrimp, and crabs, although there also are many lesser known groups as well. The current classification tells us that there are approximately 62,000 species of Crustacea in the world among 849 families. Approximately 152 of those families belong to the Decapoda. To add to this, the decapods have been referred to as “the pinnacle of crustacean evolution.” Knowing …

Phylogenetic Analyses Of The Burrowing Members In The Freshwater Crayfish Genera Fallicambarus And Procambarus In Arkansas, Timothy D. O'Connor, Dr. Keith A. Crandall
Journal of Undergraduate Research
There are an estimated 338 taxa of freshwater crayfish in the United States, with approximately 48% considered to be endangered, threatened, or of special concern (Taylor et al. 1996). Life history information for the majority of the primary burrowing species is lacking because they dig deep burrows and venture out only during breeding periods.
The Investigation Of X-Ray Diffraction Patterns From Human Hair In Correlation With Dietary Habits, Savannah Gore, Beverly L. Roeder
The Investigation Of X-Ray Diffraction Patterns From Human Hair In Correlation With Dietary Habits, Savannah Gore, Beverly L. Roeder
Journal of Undergraduate Research
Eating disorders, namely anorexia nervosa (AN) and bulimia nervosa (BN), are a serious problem affecting 1-5% of high school and college age women in the US. Unfortunately, the diagnostic methods used to determine if an individual is suffering from AN or BN are, for the most part, based on fallible self-report data. In an attempt to alleviate this problem, a quantitative, biologically based test able to accurately diagnosis AN 80% of the time using carbon and nitrogen stable isotope fractionation in hair was developed. In an effort to raise the accuracy of this test, I looked at x-ray diffraction patterns …

Chemical Analysis Of Synthetic Dimerizer Ap20187, Jad Mills, Dr. Sandra Burnett
Journal of Undergraduate Research
The synthetic dimerizer AP20187 initiates targeted dimerization of mutant FK506 binding proteins (FKBP) to study cell functions, cell signaling pathways, and protein functions. In Macrophage Fas-Induced Apoptosis (Mafia) transgenic mice, AP20187 is used to initiate Macrophage apoptosis . To determine the mechanism behind some depletion variability in Mafia mice, AP20187 was characterized and degradation was monitored using hydrogen and carbon nuclear magnetic resonance (1H- and 13C-NMR), high performance liquid chromatography (HPLC), electro spray mass spectrometry (ESMS), polarimetry, and spectrophotometry.
Cloning Bovine Ccl28, Melissa Hughes, Dr. Eric Wilson
Cloning Bovine Ccl28, Melissa Hughes, Dr. Eric Wilson
Journal of Undergraduate Research
I have successfully completed my project of cloning CCL28. CCL28 (MEC) is a protein that acts as a chemical signal in the body to attract antibody-secreting IgA cells that expresses a receptor called CCR10 to the mucosal tissue and to the mammary gland (1). CCL28 plays a vital role in allowing the maternal antibody secreting cells to home to the mammary gland and to pass antibodies to the breast-feeding infant, giving the infant passive immunity. This provides the infant with antibodies to antigens found in the mother’s environment (which is consequently the infant’s environment as well) and decreases mortality rates. …

Thymidine Kinase 1 Immunostaining For Marking The Progression Of Skin Cancer, Kendal Jensen, Dr. Kim O'Neill
Journal of Undergraduate Research
Each year in the United States there are over one million cases of nonmelanoma skin cancer. Detection of metastatic skin cancer requires skill and careful consideration of clinical and histologic features. An accurate and specific stain for early, definitive diagnosis of metastatic skin cancer would be a useful tool for clinicians. Investigations using antibodies against tumor-specific antigens (TSAs) as prognostic indicators in cancer are ongoing. A novel TSA, Thymidine Kinase 1 (TK1) has been discovered for a variety of solid tumors. This last year in Kim O’Neill’s lab I investigated the use of an antibody against TK1 for use in …
Feup Importance In The Symbiotic Infection In Sinorhizobium Melliloti, Rebecca Carlyon, Dr. Joel Griffitts
Feup Importance In The Symbiotic Infection In Sinorhizobium Melliloti, Rebecca Carlyon, Dr. Joel Griffitts
Journal of Undergraduate Research
How does infection work? How do bacteria know where they are to function within a host? These processes are vital for understanding both disease-causing and beneficial bacteria. For example, infection in alfalfa by a bacterium called Sinorhizobium meliloti is advantageous for the legume. Rhizobia infects special plant organs called root nodules where they function to fix nitrogen—a vital mechanism for the plants’ survival. This is a crucial agricultural process, yet remains a under researched subject. An important aspect of infection is that in order for it to occur, there must exist communication between the bacteria and the plant.
The Role Of Specific Estrogen-Responsive Genes In Breast Cancer Development, Laura Castillo, Dr. Chin-Yo Lin
The Role Of Specific Estrogen-Responsive Genes In Breast Cancer Development, Laura Castillo, Dr. Chin-Yo Lin
Journal of Undergraduate Research
Estrogen plays a role in the reproductive maturation of females, including breast development. It is also known that estrogen affects the development of malignant breast tumors. Estrogen works by binding to specific estrogen receptors found in the cytoplasm or near the nuclear membrane. Once bound to estrogen, these receptors diffuse into the nucleus where they bind to specific DNA sequences called estrogen-response elements. They then regulate the expression of specific genes. There are two types of estrogen receptors (ER): ERα and ERβ. Only ERα has been observed to play a role in breast cancer development. Dr. Chin-Yo Lin and associates …

The Role Of Ypo 2169 In Flea Transmission Of Plague, Paul Henry Beeston, Dr. David Erickson
Journal of Undergraduate Research
Yersinia pestis is the gram negative bacteria responsible for the disease known as the plague. It is transmitted to hosts primarily through fleas such as the Oriental rat flea North American ground squirrel flea. Y. pestis is mainly a disease that affects small mammal populations such as rats and squirrels. The environment of the rat flea and other fleas, however, is very different from small mammal hosts or human hosts. Fleas maintain a body temperature considerably lower than mammals. Fleas also have unique physiologies that greatly differ from mammals.

Finding A Correlation Between Aggressivity Of Cancer And Dna Repair Capacity, Kristie I. Aamodt, Dr. Kim L. O'Neill
Journal of Undergraduate Research
The initial proposal for this project outlined the study of the link between DNA damage and aggressiveness of cancer cells. A major portion of the project involved developing a more time-efficient method of measuring DNA repair using a fluorescent staining technique that quantifies the amount of DNA that is damaged in each sample. The staining process involves using terminal deoxytransferase (tDt), an enzyme which adds nucleotides to DNA at the 3′ end of single-strand breaks. By incubating the samples with fluorescein-conjugated dUTP in addition to the enzyme, one fluorescent molecule is incorporated for each single-strand break. The amount of fluorescence …

Retinal Detachment In Mice With Disproportionate Micromelia, Jared R. Jackson, Dr. Robert Seegmiller
Retinal Detachment In Mice With Disproportionate Micromelia, Jared R. Jackson, Dr. Robert Seegmiller
Journal of Undergraduate Research
Stickler syndrome, caused by a mutation of the Collagen 2A1 gene, is the most common cause of inherited retinal detachment in children. A mutation of the same gene in mice causes Disproportionate Micromelia (Dmm). “In cases where mouse mutations occur in genes that are also responsible for human disorders, the mouse strains provide essential model systems for studies of pathogenetic mechanisms.” The purpose of this study is to find and document evidence of retinal detachment that is hypothesized in heterozygous (Dmm/+) mutant mice.

Chondrocyte Apoptosis Correlated With Progression Of Osteoarthritis In Dmm Mice, Ryan Anderson, Dr. Robert E. Seegmiller
Journal of Undergraduate Research
Osteoarthritis (OA) is a progressive disease resulting in the degeneration of synovial joint cartilage and is the leading cause of chronic disability in the elderly1. Despite the prevalence of this disease, its pathogenesis is poorly understood. There is need for low cost, short generation animal model to study this disease. For this, we used a proven mouse model as the means for researching OA, the Disproportionate micromellia (Dmm) mouse which has been shown to develop early onset OA. One mechanism involved in OA that we are specifically researching is programmed cell death, apoptosis, of cartilage cells, chondrocytes and how it …

Across the planet, high-intensity farming has transformed native vegetation into monocultures, decreasing biodiversity on a landscape scale. Yet landscape-scale changes to biodiversity and community structure often emerge from processes operating at local scales. One common process that can explain changes in biodiversity and community structure is the creation of abrupt habitat edges, which, in turn, generate edge effects. Such effects, while incredibly common, can be highly variable across space and time; however, we currently lack a general analytical framework that can adequately capture such spatio-temporal variability. We extend previous approaches for estimating edge effects to a non-linear mixed modeling framework …
