Novel Role Of Histone Deacetylase 11 (Hdac11) In Regulating Normal And Malignant Hematopoiesis, Jie Chen
Novel Role Of Histone Deacetylase 11 (Hdac11) In Regulating Normal And Malignant Hematopoiesis, Jie Chen
USF Tampa Graduate Theses and Dissertations
During hematopoiesis, multilineage progenitor cells and the precursors are committed to individual hematopoietic lineages. In normal myelopoiesis, the immature myeloid cells (IMCs) differentiate into macrophages, neutrophils or dendritic cells. However, under tumor burden, these IMCs differentiate into myeloid derived suppressor cells (MDSCs) result in an up-regulation of immune suppressive factors and pro-tumor effect. The development of normal or malignant is tightly controlled by endogenous signals such as transcription factors and epigenetic regulations. HDAC11 is the newest identified members of the histone deacetylase (HDAC) family. Previous study in our group had identified HDAC11 as a negative regulator of interleukin 10 (IL-10) …

Radiation-induced lung injury (RILI) is caused by an early inflammatory process triggered by damage to lung parenchyma, epithelial cells, vascular endothelial cells and stroma. Initially, oxidative injuries after radiation induce altered expression of pro-inflammatory cytokines. Infiltrating inflammatory cells are stimulated and activated, producing additional mediators, resulting in a cytokine cascade. The expansion and perpetual activation of inflammatory cells, as well as lung parenchyma, lead to clinical pneumonitis. Activated cells produce molecular mediators and growth factors that affect the proliferation and gene expression of lung fibroblasts. This process leads to increased collagen synthesis and deposition, eventually leading to the development of …

Dissertations & Theses (Open Access)
Among the first white blood cells to respond to bacterial and fungal infections, neutrophils are produced in the bone marrow, released into circulating blood, and recruited to inflamed tissue. The cytokine granulocyte colony-stimulating factor (G��CSF) is used clinically to induce neutrophil mobilization from the marrow. This process was previously demonstrated to require the STAT3 transcription factor (signal transducer and activator of transcription 3), the principal signaling molecule activated upon G-CSF-binding of its receptor, but the mechanism was unknown. The chemokines KC (Cxcl1) and MIP-2 (Cxcl2), and their shared receptor CXCR2 (l8rb), also stimulate neutrophil mobilization, in contrast to SDF-1 (Cxcl12), …
