Modulation Of Bax/Bak Dependent Apoptosis By Sirtuin 3 And Mitochondrial Permeability Transition By Sirtuin 4, Manish Verma
Modulation Of Bax/Bak Dependent Apoptosis By Sirtuin 3 And Mitochondrial Permeability Transition By Sirtuin 4, Manish Verma
Graduate School of Biomedical Sciences Theses and Dissertations
Mitochondria are dynamic organelles that regulate a myriad of cellular functions, including energy production and metabolic regulation. Mitochondria are also a critical regulator of cell death signaling cascades modulating both apoptotic and necrotic cell death. However, what determines which cell death pathway is activated is still unclear. The mitochondrial/intrinsic pathway of apoptosis is dependent on the activation of pro-apoptotic proteins, Bax and Bak, which induce mitochondrial outer membrane permeabilization (MOMP). Once the integrity of outer mitochondrial membrane (OMM) is compromised, pro-apoptotic intermembrane space proteins like cytochrome c, Smac/Diablo, Omi/HtrA2 and AIF are released into the cytoplasm, which activates the post-mitochondrial …
Expression Of The Chemokine Receptor, Cxcr4, And Its Ligand, Sdf-1, Are Increased In Purkinje Cells Of The Multiple System Atrophy Cerebellum, Megan Welter
Masters Theses
Multiple System Atrophy (MSA) is a sporadic, neurodegenerative disease that consists of three conditions: autonomic dysfunction, Parkinsonism and cerebellar ataxia. Our lab conducted an Affymetrix global gene expression analysis using pons tissue of MSA patients to determine genes that are differentially expressed when compared to non- MSA controls. This study identified upregulated genes, including the C-X-C chemokine receptor type 4, CXCR4, to which stromal cell-derived factor-I (SDF-1) is the natural ligand. The CXCR4/SDF-1 signaling pair has been sho.wn to play multiple roles in the brain, such as inducing neuronal apoptosis and promoting leukocyte recruitment during inflammation. The MSA cerebellum presents …
Cytotoxic Properties Of Novel Platinum Compounds, Bbr3610-Dach And Trans-4-Nbd In Tumor Cells: Cellular Effects Of 1, 2-Dach And Nbd Ligands, Vijay Menon
Theses and Dissertations
Platinum-based chemotherapeutics are used for the treatment of a wide range of cancers and a number of attempts have been made toward developing compounds with better cellular stability and similar or enhanced cytotoxicity as compared to their predecessors. The first part of the work reported here focuses on the cellular effects of the metabolically stable dinuclear platinum compound, BBR3610-DACH. Comet assay showed this compound to form interstrand crosslinks, a highly toxic DNA lesion in HCT116 cells, at equimolar concentrations to its parental compound, BBR3610. Cell cycle studies showed that BBR3610-DACH causes G1/S and G2/M cell cycle arrest with S phase …
Functional Study Of Hemogen Knockout Mouse Model, Peng Gao
Functional Study Of Hemogen Knockout Mouse Model, Peng Gao
Theses and Dissertations (ETD)
Mouse Hemogen (Hemgn) is regarded as a homologue of human Erythroid Differentiation Associated Gene (EDAG). EDAG overexpression has been postulated for association with some leukemia cases. Meanwhile, Hemgn has been found to contribute to Hoxb4 mediated hematopoietic stem cell expansion. Based on these postulations and evidences, a Hemgn knockout mouse model has been generated to study its function in normal and stress hematopoiesis. I confirmed the Hemgn expression in hematopoietic organs including bone marrow and spleen, as well as round spematids in testis. Hemgn is expressed in mouse hematopoietic stem cells and erythroid progenitor cells. Moreover, Hemgn was also found …
