The Role Of Sr-B1 In Lipid Metabolism And Inflammation In 3t3-L1 Adipocytes, Christina Jiang
The Role Of Sr-B1 In Lipid Metabolism And Inflammation In 3t3-L1 Adipocytes, Christina Jiang
University Scholar Projects
Obesity is associated with a number of complications that may increase the risk for chronic disease, including inflammation and dysfunctional high-density lipoprotein (HDL) particles. Scavenger receptor class B member 1 (SR-B1) is an HDL receptor found in the cell plasma membrane involved in cholesterol exchange and the initiation of intracellular signaling cascades. During the process of adipocyte (fat cell) formation (adipogenesis), there is a delicate balance of transcriptional programs that affect cholesterol transport and facilitate lipid accumulation. Mice fed a high fat diet have increased SR-B1 mRNA expression in adipose tissue depots. Furthermore, SR-B1 mRNA expression was significantly increased in …
Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte
Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte
University Scholar Projects
Sickle cell disease (SCD) has been shown to be associated with decreased baseline immunity and thus increased susceptibility to infection. I sought to discern possible causes of this by looking into the correlations between SCD and hematopoiesis, the immune system and the neuroendocrine system, and ultimately by conducting experiments surrounding the impaired immune system of SCD. These experiments focused on the potential causes and effects of the diminution of B-1a cells in the SCD spleen. Adoptive transfers, infections with Streptococcus pneumoniae, and histologic imaging were conducted to establish if the diminution of the B-1a cells in the SCD spleen …
Characterization Of Myod And Myf5 Double-Knockout Muscle Stem Cells During Muscle Development, Andreea Dinicu
Characterization Of Myod And Myf5 Double-Knockout Muscle Stem Cells During Muscle Development, Andreea Dinicu
University Scholar Projects
MyoD and Myf5 are transcription factors that regulate myogenesis by promoting satellite cell transcription. The two genes are known to display functional redundancy. Both genes are considered myogenic determination genes and are expressed in satellite cells. The fate of myogenic precursors in the absence of both MyoD and Myf5 remains largely unknown. We aimed to begin attaining this knowledge as part of this project. We utilized a CreLoxP system to control the expression of MyoD in mice lacking Myf5. MyoD was knocked out at embryonic day (E) 11.5 during myogenesis. Limbs were collected from experimental mice following tamoxifen injection. …
Comparison Of Feather Pigments In Red-Winged Blackbirds (Agelaius Phoenicus) Between Historical And Modern Samples, Genevieve Nuttall
Comparison Of Feather Pigments In Red-Winged Blackbirds (Agelaius Phoenicus) Between Historical And Modern Samples, Genevieve Nuttall
University Scholar Projects
Coloration is vital to birds; it is involved in mating, territorial display, communication, camouflage, and predation. Birds rely on their environment for the raw materials necessary to make most colors present in their feathers. As a result, habitat quality can have lifetime fitness consequences through the color pathway. Widescale habitat change has affected the quality of habitats accessible to birds worldwide. Consequently, the availability of pigment-containing resources within many altered habitats has shifted, leading to modification in the coloration of some birds’ feathers. I hypothesized that the red pigmentation in the feather shoulders, or epaulets, of red-winged blackbirds (Agelaius …
Beyond Capture: Development And Validation Of A Method To Assess Body Condition In Mule Deer (Odocoileus Hemionus) Using Camera Traps, Rachel A. Smiley 6820420
Beyond Capture: Development And Validation Of A Method To Assess Body Condition In Mule Deer (Odocoileus Hemionus) Using Camera Traps, Rachel A. Smiley 6820420
University Scholar Projects
Advances in technology and availability associated with camera traps have resulted in a rapid rise in their use to monitor wildlife distribution, abundance, and behavior. We focus on assessing body condition, a new application of camera traps. Body condition indices must relate to the percent body fat if they are to be useful. To acquire measurements of body fat, most body condition indices require capture or mortality of animals to estimate, which has limitations when applied to free-ranging animals. We developed a non-invasive, visual body condition index (VBCI) to assess body condition of mule deer that can be applied …
