Acl Injury, A Time Course Study Of Transcriptional Changes, Thomas Carter
Acl Injury, A Time Course Study Of Transcriptional Changes, Thomas Carter
Theses and Dissertations--Medical Sciences
ACL tear is a common injury in the United States with a significant cost and time burden during recovery; reconstructive surgery often results in weakened quadricep muscle and higher risk of posttraumatic osteoarthritis. Prior research has highlighted cellular derangements within the quadriceps after ACL injury and reconstruction, but the early molecular effectors of cellular dysfunction remain to be identified. To further understand the molecular effectors of quadriceps dysfunction following ACL injury, this study aims to quantify the timing and magnitude of transcriptional differences between the quadriceps muscle of injured and contralateral non-injured limbs. These data will provide insight into the …

S. Gordonii-Produced Hydrogen Peroxide Modulates Mir-663a And Ccl20 Expression In Oral Epithelial Cells, Marshall Houston Maynard

The mechanisms through which a persistent recognition of commensal bacteria by oral epithelial cells (OECs) mitigates an uncontrolled inflammatory response of the oral mucosa remain unknown. CCL20 secretion by OECs in response to pathogenic bacteria is regulated by S. gordonii (Sg)-induced miR-663a; nevertheless, the mechanisms involved in these Sg-modulated responses remain to be elucidated. Since Sg is a hydrogen peroxide (H2O2) producer, and H2O2 has been shown to stimulate miRNA expression, we hypothesized that H2O2 could be involved in Sg-induced miR663a and CCL20 responses. Expression of miR663a …
The Role Of Vascular Endothelial Growth Factor In Leukemia Trafficking, Shaw Powell
The Role Of Vascular Endothelial Growth Factor In Leukemia Trafficking, Shaw Powell
Theses and Dissertations--Medical Sciences
Vascular endothelial growth factor (VEGF) is a signaling protein involved in inducing and regulating endothelial cell proliferation and function (Duffy et al 2000). VEGF is also involved in cancer progression, as it induces vascular permeability and promotes angiogenesis to tumor laden areas, giving cancer cells critical oxygen and nutrients (Hoeppner et al.,2012. Studies indicate VEGF prevents lymphoblast apoptosis, which may contribute to leukemia formation and enable the proliferation of leukemic cells (Duffy et al 2000). Ongoing research seeks to further examine VEGF in leukemia, using a rag2:GFP-Myc expressing transgenic zebrafish as the animal model of T-cell Acute Lymphoblastic Leukemia (T-ALL). …
