Population Demographics And Genetic Structure Of Black Bears In Coastal Louisiana, Jesse Charles Troxler
Population Demographics And Genetic Structure Of Black Bears In Coastal Louisiana, Jesse Charles Troxler
Masters Theses
The range and abundance of the Louisiana black bear (Ursus americanus luteolus) were greatly diminished during the 20th century. This subspecies was reduced to 3 small, isolated subpopulations in Louisiana as bottomland hardwood habitat was converted to agriculture. These bears were listed as threatened by the U.S. Fish and Wildlife Service in 1992 and a recovery plan was published in 1995. Recovery requires estimates of population parameters to evaluate current population status and future viability. I conducted a mark-recapture study from 2010 to 2012 to estimate demographic parameters of the coastal population of Louisiana black bears. Because inbreeding …
Identification Of Set1 Target Genes, William Beyer, Scott D. Briggs
Identification Of Set1 Target Genes, William Beyer, Scott D. Briggs
The Summer Undergraduate Research Fellowship (SURF) Symposium
The Set1 complex, a histone methyltransferase complex found in S. cerevisiae (budding yeast), is the only histone methyltransferase responsible for catalyzing methylation of histone H3 at Lysine 4. It possesses homologues in other species, humans included. While yeast only have the Set1 complex, the human homologues of the yeast Set1 complex include mixed-lineage leukemia family (MLL1-4), Set1 A, Set1 B, among others. MLL1-4 has been shown to play a role in transcription, cell type specification, and the development of leukemia. One application of characterizing the role of a protein is that the information gained can provide insight into the function …
The Importance Of Epigenetic Phenomena In Regulating Activity Of The Genetic Material, Sin Chan
The Importance Of Epigenetic Phenomena In Regulating Activity Of The Genetic Material, Sin Chan
Senior Honors Projects
Genetics has taught us that genes are represented as discrete sequences within a larger DNA molecule found embedded within the chromosomes of a living cell. Collectively these chromosomes and their associated genes carry all of the instructions for life. Until recently, the prevailing thought has been that genes are destiny in the life of an individual since the genes carry the information that determines the general traits and characteristics associated with that individual. The relatively recent understanding of mechanisms that underlie epigenetic phenomena has led to a rethinking of this concept. Epigenetics describes cellular mechanisms that explain how two individuals …
Development Of Tools To Assess The Effects Of Lunasin On Normal Development And Tumor Progression In Drosophila Melanogaster, Gillian E. Jones
Development Of Tools To Assess The Effects Of Lunasin On Normal Development And Tumor Progression In Drosophila Melanogaster, Gillian E. Jones
Masters Theses & Specialist Projects
Soy contains many bioactive molecules known to elicit anti-cancer effects. One such peptide, Lunasin, has been shown to selectively act on newly transformed cells while having no cytotoxic effect on non-tumorigenic or established cancer cell lines. In this study we attempt to understand the developmental effects of Lunasin overexpression in vivo and create reagents that will help us understand Lunasin’s anti tumorigenic effects in an intact organism. cDNA encoding lunasin and EGFP-lunasin were cloned into pUAST and microinjected into Drosophila embryos. Tissue-specific overexpression of EGFP-Lun in the resulting transgenic lines was accomplished by crossing transgenics to various GAL4 driver lines. …
Encyclopedia Of Animal Behavior, A. Payne, P. Starks, Aviva Liebert
Encyclopedia Of Animal Behavior, A. Payne, P. Starks, Aviva Liebert
Aviva E Liebert
The Encyclopedia of Animal Behavior has engaged-with great success-the efforts of many of the best behavioral biologists of the 21st century. Section editors drawn from the most accomplished behavioral scientists of their generation have enrolled an international cast of highly respected thinkers and writers-all of whom have taken great care and joy in illuminating every imaginable corner of animal behavior. This comprehensive work covers not only the usual topics such as communication, learning, sexual selection, navigation, and the history of the field, but also emerging topics in cognition, animal welfare, conservation, and applications of animal behavior. The large section on …
Engaging Students In A Bioinformatics Activity To Introduce Gene Structure And Function, Barbara J. May
Engaging Students In A Bioinformatics Activity To Introduce Gene Structure And Function, Barbara J. May
Biology Faculty Publications
Bioinformatics spans many fields of biological research and plays a vital role in mining and analyzing data. Therefore, there is an ever-increasing need for students to understand not only what can be learned from this data, but also how to use basic bioinformatics tools. This activity is designed to provide secondary and undergraduate biology students to a hands-on activity meant to explore and understand gene structure with the use of basic bioinformatic tools. Students are provided an “unknown” sequence from which they are asked to use a free online gene finder program to identify the gene. Students then predict the …
Examining The Functional Role Of Dprl-1 In Drosophila Melanogaster, John Valenzuela
Examining The Functional Role Of Dprl-1 In Drosophila Melanogaster, John Valenzuela
Summer Research
The Phosphatase of Regenerating Liver (PRL) family of proteins control cell growth, motility and proliferation. They have been shown to elevate the levels of these functions, leading to an increase in cancer metastasis (“malignancy”), when they are overexpressed. The goal of this experiment is to knockout PRL gene expression to examine the general function of PRL proteins. Drosophila melanogaster have only one copy of the PRL gene (dPRL-1), as opposed to humans and other mammals, which have 3. Thus, using P-element imprecise excision to create mutant strains either fully lacking or with decreased function of the dPRL-1 protein, …
