Adult stem cells represent a potential source for cell-based therapy of cancer. The present study evaluated the potential of bone marrow-derived mesenchymal stem cells (MSC), genetically modified to express interferon (IFN)-alpha, for the treatment of lung metastasis in an immunocompetent mouse model of metastatic melanoma. A recombinant adeno-associated(More)
OBJECTIVES The distant organs to which breast cancer preferentially metastasizes are of significant clinical importance. METHODS We explored the relationship between the clinicopathologic factors and the common sites of distant metastasis in 531 consecutive patients with advanced breast cancer. RESULTS Breast cancer subtype as a variable was(More)
Mesenchymal stem cells (MSCs) are the most popular among the adult stem cells in tissue engineering and regenerative medicine. Since their discovery and functional characterization in the late 1960s and early 1970s, MSCs or MSC-like cells have been obtained from various mesodermal and non-mesodermal tissues, although majority of the therapeutic applications(More)
PURPOSE Current evidence indicates that an osteoblast lesion in prostate cancer is preceded by osteolysis. Thus, prevention of osteolysis would reduce complications of bone metastasis. Bone marrow-derived mesenchymal stem cells have the ability to differentiate into osteoblast and produce osteoprotegerin, a decoy receptor for the receptor activator for(More)
BACKGROUND The antimicrobial peptide, leucine-leucine-37 (LL-37), stimulates proliferation, angiogenesis, and cellular migration, inhibits apoptosis and is associated with inflammation. Since these functional processes are often exaggerated in cancer, the aim of the present study was to investigate the expression and role of LL-37 in prostate cancer (PCa)(More)
Elevated levels of plasmacytoid dendritic cells (pDC) have been reported in breast cancer patients, but the significance remains undefined. Using three immunocompetent mouse models of breast cancer bone metastasis, we identified a key role for pDC in facilitating tumor growth through immunosuppression and aggressive osteolysis. Following infiltration of(More)
Antiangiogenic therapy is a promising alternative for prostate cancer growth and metastasis and holds great promise as an adjuvant therapy. The present study evaluated the potential of stable expression of angiostatin and endostatin before the onset of neoplasia and during the early and late stages of prostate cancer progression in transgenic adenocarcinoma(More)
INTRODUCTION Bone metastasis affects the majority of patients with advanced breast cancer and no adequate therapy exists. Bisphosphonates, like zoledronic acid, inhibit the osteolytic component of tumor growth in osseous tissues, but these drugs are not curative. The current study evaluated the combination of zoledronic acid with death receptor 5 agonists(More)
Enhanced production of receptor activator of nuclear factor-kappaB ligand (RANKL) and its binding to RANK on the osteoclasts have been associated with osteolysis in breast cancer bone metastasis. Osteoprotegerin (OPG) is a decoy receptor that prevents RANKL-RANK interaction. This study determined the effects of sustained expression of OPG using a(More)
PURPOSE The aims of this study were to investigate telomere function in normal and Barrett's esophageal adenocarcinoma (BEAC) cells purified by laser capture microdissection and to evaluate the effect of telomerase inhibition in cancer cells in vitro and in vivo. EXPERIMENTAL DESIGN Epithelial cells were purified from surgically resected esophagi.(More)
