Hematopoietic stem cells (HSCs) reside predominantly in bone marrow, but low numbers of HSCs are also found in peripheral blood. We examined the fate of blood-borne HSCs using genetically marked parabiotic mice, which are surgically conjoined and share a common circulation. Parabionts rapidly established stable, functional cross engraftment of(More)
The roles of the mitogen-activated kinase protein (MAPK) pathway, nuclear factor-kappa B (NF-kappaB), and activator protein-1 (AP-1) in cellular responses to growth factors and mitogen are well established. However, the manner by which these proliferative pathways are affected by the tumor suppressor protein p53 is not fully understood. We report here the(More)
We evaluated the efficacy and safety of capecitabine and temozolomide (CAPTEM) in patients with metastatic neuroendocrine tumors (NETs) to the liver. This regimen was based on our studies with carcinoid cell lines that showed synergistic cytotoxicity with sequence-specific dosing of 5-fluorouracil preceding temozolomide (TMZ). A retrospective review was(More)
BACKGROUND AND IMPORTANCE Rarely, corticotrophic pituitary tumors take on an aggressive form characterized by rapid growth, invasion into local structures, compression of cranial nerves, and possible spread to distant sites. When conventional surgery, radiation therapy, and hormones fail to control progression and symptoms, alternative therapies are needed.(More)
BACKGROUND Neuroendocrine tumors are uncommon tumors that are histopathologically and biologically heterogeneous and include the multiple endocrine neoplasia (MEN) 1 and 2 syndromes. The morbidity of MEN-1 and MEN-2 is often due to the symptomatology of the endocrine hormones produced, and the mortality mainly occurs from hepatic dysfunction incurred by(More)
recently, we published an important report on the role of radiotherapy in pancreatic neuroendocrine tumors (PNET) consisting of our experience and the data presented at the 2012 ASCO Gastrointestinal Cancers Symposium by the University of Maryland School of Medicine, Baltimore, MD, USA and Johns Hopkins University School of Medicine, Baltimore, MD, USA [1,(More)
BACKGROUND Gastrointestinal stromal tumor (GIST) is a mesenchymal malignancy of the gastrointestinal tract. Imatinib mesylate (Gleevec(®), ST1571, Novartis Pharmaceuticals, Basel, Switzerland) is a selective inhibitor of break point cluster-Ableson (BCR-ABL), c-Kit, and platelet-derived growth factor receptor alpha (PDGFRα) tyrosine kinases. Imatinib has(More)
