Theses, Dissertations and Capstones

Prior to 1988, two subspecies of the mosquitofish Gambusia affinis (G. a. affinis and G. a. holbrooki) were recognized along the Gulf and Atlantic Coasts of the United States. Based on electrophoretic analysis, subsequent investigators recognized G. holbrooki and G. affinis as separate species. Populations in drainages west of Mobile Bay were considered G. affinis, and those east of this divide being G. holbrooki. The only mosquitofish population in West Virginia is found in the Meadow River wetlands (1392 ha). This wetland complex is located at the western end of Greenbrier County in the Allegheny Mountain Province. …

An Immunomodulating Mycotoxin Interferes With The Development Of Autoimmune Diabetes In Diabetes-Prone Bb/Wor Rats, Honggang Liu

Theses, Dissertations and Capstones

Various fungal products have immunomodulating activity and some have been studied regarding prevention of transplantation rejection. Prior to this investigation, the mycotoxin, gliotoxin (GT), has never been investigated as an immunotherapeutic drug for autoimmune disease. GT is a fungal secondary metabolite and a member of the epipolythiodioxopiperazine (ETP) family which has been shown to inhibit phagocytosis, induction of cytolytic T cells and the proliferation of T cells following mitogen stimulation. GT also induces in vitro apoptosis in certain immune cell types. More importantly, GT exhibits selective activity towards cells of hemopoietic origin.

Autoimmune diseases are disorders caused by immune responses …

Theses, Dissertations and Capstones

The (3)H-tetracycline bone labeling procedure was employed to monitor bone resorption from urinary loss curves in male and female rats of various ages. In addition, whole body dry skeletal mass and the loss of (3)H-tetracycline from individual bones was determined. It was found that the dry skeletal mass/body mass ratio of 24-week-old females was 30-40% greater than that for males. The urinary loss of (3)H-tetracycline was described by a double exponential equation indicating the presence of two distinct and independent exchangeable bone compartments. Both compartments decrease in size with age, but their label loss activities were different. The label loss …


Effect Of Retinoic Acid On The Expression And Function Of Ap-1 Transcription Factor In B16 Mouse Melanoma Cells: Role Of Protein Kinase, Sejal H. Desai Jan 1996

Effect Of Retinoic Acid On The Expression And Function Of Ap-1 Transcription Factor In B16 Mouse Melanoma Cells: Role Of Protein Kinase, Sejal H. Desai

Theses, Dissertations and Capstones

Retinoic acid (RA) induces differentiation of B16 mouse melanoma cells. This differentiation is accompanied by an increase in protein kinase Ca (PKCα) protein level and selective enrichment in nuclear-associated PKCα. PKC is thought to regulate gene expression through the TPA response element (TRE). This element is specifically recognized by the AP-1 transcription factor composed of jun and fos family members. In this study, I have analyzed the effect of RA on the expression and function of AP-1 in B16 mouse melanoma cells. Transient transfection analysis of B16 cells using leuciferase reporter gene constructs with or without AP-1 elements indicated that …


Regulation Of Melanogenesis In B16 Mouse Melanoma Cells By Protein Kinase C (Pkc), Harish Mahalingam Jan 1996

Regulation Of Melanogenesis In B16 Mouse Melanoma Cells By Protein Kinase C (Pkc), Harish Mahalingam

Theses, Dissertations and Capstones

The pigment cell-specific expression of tyrosinase and TRP1 has been shown to be important for the production of melanin in pigmented cells. Using a pigmented cell line, B16 mouse melanoma, we obtained evidence that PKC plays a major role in regulating melanogenesis. Chronic treatment with phorbol dibutyrate (PDBu) leads to downregulation of PKC activity and protein levels. This is accompanied by a loss of pigmentation which is correlated with a 50% reduction and a complete loss of TRP1 and tyrosinase respectively. Similar results were obtained with Northern and Western blotting indicating that PKC may regulate the steady state levels of …
