The Role Of Brct-Containing Proteins Brca1 And Paxip1 In Cancer, Ankita Jhuraney
The Role Of Brct-Containing Proteins Brca1 And Paxip1 In Cancer, Ankita Jhuraney
USF Tampa Graduate Theses and Dissertations
Modular domains of proteins are important in cellular signaling processes. Eukaryotic cells are constantly undergoing DNA damage due to exogenous and endogenous sources of damage. The DNA damage response (DDR) involves a complex network of signaling events mediated by modular domains such as the BRCT (BRCA1 C-terminal) domains. Therefore, proteins containing BRCT domains are important for DNA damage detection and signaling. In this dissertation, we focus on two BRCT-containing proteins BRCA1 and PAXIP1. BRCA1 is a gene that is known to be associated with increased risk of hereditary breast and ovarian cancer. Germline variants of BRCA1 are assessed to determine …
Targeting T-Bet For Prevention Of Graft-Versus-Host Disease And Leukemia Relapse After Allogeneic Hematopoietic Stem Cell Transplantation, Jianing Fu
USF Tampa Graduate Theses and Dissertations
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective therapeutic option for many malignant diseases. However, the efficacy of allo-HSCT is limited by the occurrence of destructive graft-versus-host disease (GVHD). Since allogeneic T cells are the driving force in the development of GVHD, their activation, proliferation, and differentiation are key factors to understanding GVHD pathogenesis. On the other hand, antigen-presenting cells (APCs) are essential for allogeneic T-cell priming and the development of GVHD. The T-box transcription factor T-bet is a master regulator for IFN-γ production and Th1 differentiation. T-bet also regulates the functions of APCs including dendritic cells (DCs) and …
