Development Of A Crispr System To Mutate Lpar4 In Chick Retinal Ganglion Cells, Garrett Driscoll
Development Of A Crispr System To Mutate Lpar4 In Chick Retinal Ganglion Cells, Garrett Driscoll
Graduate Theses
Growth cones direct axon pathfinding during neural development by detecting environmental stimuli, known as axon guidance molecules. In vitro studies have shown inhibitory axon guidance molecules to cause growth cones to change morphology to what is called a collapsed growth cone. Lysophosphatidic acid (LPA) has been demonstrated to collapse growth cones in culture, and thus it may act as an inhibitory molecule. However, identification of what LPA receptor is responsible for this physiological response is unknown. To investigate which receptor elicits collapse, we focused on LPA receptor-4 (LPA4) by designing a CRISPR construct to mutate Lpar4 in chick retinal ganglion …
Effect Of Morinda Citrifolia (Noni)-Enriched Diet On Hepatic Heat Shock Protein And Lipid Metabolism-Related Genes In Heat Stressed Broiler Chickens, Joshua Flees
Graduate Theses and Dissertations
Heat stress (HS) has been reported to alter fat deposition in broilers, however the underlying molecular mechanisms are not well-defined; therefore, the objectives of the current study were to: (1) determine the effects of acute (2 h) and chronic (3 wk) HS on the expression of key molecular signatures involved in hepatic lipogenic and lipolytic programs; and (2) assess if diet supplementation with dried Noni medicinal plant (0.2% of the diet) modulates these effects. Broilers (n=480 males, 1 d) were randomly assigned to 12 environmental chambers, subjected to two environmental conditions (HS at 35°C vs. thermoneutral condition [TN] at 24°C) …
Avian And Mammalian Facilitative Glucose Transporters, Mary Shannon Byers, Christianna Howard, Xiaofei Wang
Avian And Mammalian Facilitative Glucose Transporters, Mary Shannon Byers, Christianna Howard, Xiaofei Wang
Biology Faculty Research
The GLUT members belong to a family of glucose transporter proteins that facilitate glucose transport across the cell membrane. The mammalian GLUT family consists of thirteen members (GLUTs 1–12 and H+-myo-inositol transporter (HMIT)). Humans have a recently duplicated GLUT member, GLUT14. Avians express the majority of GLUT members. The arrangement of multiple GLUTs across all somatic tissues signifies the important role of glucose across all organisms. Defects in glucose transport have been linked to metabolic disorders, insulin resistance and diabetes. Despite the essential importance of these transporters, our knowledge regarding GLUT members in avians is fragmented. It is clear that …
Leptin Regulates The Expression Of Autophagy-Related Genes In Chickens, Peter Olawale Ishola
Leptin Regulates The Expression Of Autophagy-Related Genes In Chickens, Peter Olawale Ishola
Graduate Theses and Dissertations
Autophagy or cellular self-digestion, a lysosomal degradation pathway that is conserved from yeast to human, plays a key role in recycling cellular constituents, including damaged organelles. It also plays a pivotal role in the adaptation of cells to a plethora of distinct stressors including starvation. Autophagy has been extensively studied in mammals and yeast, but little is known in avian species. Thus, the major objective of the present study was to determine the effects of leptin on autophagy-related genes in chicken hypothalamus, muscle and liver. Leptin is an adipocytokine that is mostly produced by white adipose cells in mammals (as …
