Abstract
Prostate cancer (PCa) is the second leading cause of cancer-related deaths among men. Evidence suggests that age and obesity, conditions associated with adipocyte accumulation in the bone marrow, are linked to increased risk of developing PCa and progressing to metastatic disease. Studies presented in this dissertation were based on the hypothesis that metastatic progression in bone is a result of a cooperative effort between bone marrow adipocytes, macrophages, osteoclasts, and PCa cells. We specifically focused on two adipocyte-supplied chemokines, CXCL1 and CXCL2, and bone marrow macrophage-secreted osteopontin as key drivers of pro-inflammatory environment in the bone marrow and important …

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 …
