Differential Effects Of Kim-1 In Subcutaneous And Orthotopic Renca Models Of Kidney Cancer, Demitra M. Yotis Dy
Differential Effects Of Kim-1 In Subcutaneous And Orthotopic Renca Models Of Kidney Cancer, Demitra M. Yotis Dy
Electronic Thesis and Dissertation Repository
Renal Cell Carcinoma (RCC) is the most common and fatal type of kidney cancer. Over 30% of patients that are diagnosed with RCC exhibit metastases. Almost 88% of patients with distant metastases succumb to the disease within 5 years of diagnosis. Kidney Injury Molecule-1 (KIM-1) is a cell surface glycoprotein that is not expressed in a healthy kidney but becomes highly expressed on proximal tubular epithelial cells (PTECs) following injury. Data from the Cancer Genome Atlas (TCGA) reveals that >90% of RCC tumours express KIM-1 mRNA and that higher expression levels correlate with increased overall survival rates of patients. The …
Targeting Cd5 To Enhance Immune T Cell Activation And Function In Treatment Of Solid Tumours, Faizah Alotaibi
Targeting Cd5 To Enhance Immune T Cell Activation And Function In Treatment Of Solid Tumours, Faizah Alotaibi
Electronic Thesis and Dissertation Repository
CD5 is a member of scavenger receptor cysteine-rich superfamily that is expressed primarily on T cells. It can attenuate T-cell receptor signaling and impair cytotoxic T lymphocyte (CTL) activation and is a therapeutic targetable tumour antigen expressed on leukemic T and B cells. However, the potential therapeutic effect of functionally blocking CD5 to increase T cell anti-tumour activity against tumours (including solid tumours) has not been explored. CD5- solid tumours in CD5 knockout mice display increased in anti-tumour immunity. Hence, blocking CD5 function may have a potential therapeutic effect by enhancing CTL function. Here, I assessed CD5 levels in …
Cell-Free Dna Release During Programmed Cell Death In Kidney Ischemia Reperfusion Injury, Alexander Dionne
Cell-Free Dna Release During Programmed Cell Death In Kidney Ischemia Reperfusion Injury, Alexander Dionne
Electronic Thesis and Dissertation Repository
Transplantation is invariably associated with ischemia reperfusion injury (IRI) which causes organ dysfunction. IRI is also directly linked to several forms of programmed cell death including apoptosis and necroptosis, which increase kidney dysfunction, promote inflammation and may contribute to premature graft failure. The contribution of necroptosis and apoptosis following kidney IRI to cell-free DNA (cfDNA) generation and the potential of cfDNA to activate effectors such as NK cells involved in kidney IRI have not been defined. Our data indicate that necroptotic microvascular endothelial cells (MVECs) release considerably more cfDNA than apoptotic MVECs or untreated controls (p
Granulocyte Colony-Stimulating Factor: Its Role In Gut-Homing Macrophage Generation And Colitis, And Production By Probiotics, Shahab Meshkibaf
Granulocyte Colony-Stimulating Factor: Its Role In Gut-Homing Macrophage Generation And Colitis, And Production By Probiotics, Shahab Meshkibaf

The pleiotropic cytokine granulocyte-colony stimulatory factor (G-CSF) is mainly required for the generation of neutrophils, but its role in macrophage generation has also been reported. In addition, G-CSF is effective for the down-regulation of inflammatory cytokines and ameliorating gut disorders, such as colitis. However, the G-CSF function in macrophage generation and gut immunity remains unclear. The first focus of this thesis was to assess the role of G-CSF in macrophage generation and its contribution to gut immunity. G-CSF was found to promote the generation of Gr-1high/F4/80+ macrophages in macrophage (M)-CSF-treated bone marrow cells, most likely through suppressing cell death. Gr-1high …
Transcriptional Regulation Of Peptidylarginine Deiminase Type Iv: Implications For Rheumatoid Arthritis, Ali Abbas
Electronic Thesis and Dissertation Repository
High titers of anti-citrullinated protein antibodies have been detected in sera of rheumatoid arthritis (RA) patients, implicating citrullinating enzymes in the pathogenesis of RA. Peptidylarginine deiminase type IV (PAD4) is a member of the PAD family of enzymes that catalyze the post- translational modification of arginine to citrulline and has been linked with RA. However, little is known about its transcriptional regulation. Therefore, our aim was to determine how transcription of PAD4 is activated in the myeloid lineage. Using bioinformatics, a potential nuclear factor kappa B (NF-kB) binding site was identified on the PAD4 promoter. Luciferase assays were used to …
