After prostate cancer cells (PCa) arrive in bone, interactions with cells that include long bone osteoblasts (LBOB) and bone marrow stromal cells (BMSC) lead to metastasis formation. The effect of heterotypic cell–cell contact between PCa cells and BMSC or LBOB on PCa cell gene expression is poorly understood. To establish the role of heterotypic contact in(More)
Cell adhesion molecules have been implicated in the colonization of cancer cells to distant organs. Prostate cancer (PCa) has a propensity to metastasize to bone, and cadherin-11, which is an osteoblast cadherin aberrantly expressed in PCa cells derived from bone metastases, has been shown to play a role in the metastasis of PCa cells to bone. However, the(More)
UNLABELLED Cadherin-11 (CDH11) is a member of the cadherin superfamily mainly expressed in osteoblasts but not in epithelial cells. However, prostate cancer cells with a propensity for bone metastasis express high levels of cadherin-11 and reduced levels of E-cadherin. Downregulation of cadherin-11 inhibits interaction of prostate cancer cells with(More)
Induction of new bone formation is frequently seen in the bone lesions from prostate cancer. However, whether osteogenesis is necessary for prostate tumor growth in bone is unknown. Recently, 2 xenografts, MDA-PCa-118b and MDA-PCa-133, were generated from prostate cancer bone metastases. When implanted subcutaneously in severe combined immunodeficient(More)
Background The purposes of this study were to establish a novel blood pressure (BP) scoring method and to correlate it with clinical response in advanced cancer patients treated with anti-vascular endothelial growth factor (VEGF) therapies. Methods We retrospectively analyzed data for 368 patients from 23 clinical trials that included at least one anti-VEGF(More)
Men with castration-resistant prostate cancer (PCa) frequently develop metastasis in bone. The reason for this association is unclear. We have previously shown that cadherin-11 (also known as OB-cadherin), a homophilic cell adhesion molecule that mediates osteoblast adhesion, plays a role in the metastasis of PCa to bone. Here, we report that(More)

BACKGROUND Ductal or endometrioid adenocarcinoma of the prostate may be a subtype of prostate cancer that is amenable to aggressive local therapeutic strategies. The authors of this report investigated the clinical outcome of patients who had prostate ductal adenocarcinoma after primary radical prostatectomy or radiotherapy. METHODS The clinical features(More)
A major goal of cancer research is to acquire knowledge that enables us to understand cancer and help mankind. To reach this goal, we need to conduct cancer research according to the scientific method. The scientific method stipulates that we begin by making observations of cancer. Then, we formulate hypotheses to explain our observations and devise(More)
Lhermitte-Duclos disease (LDD) (dysplastic cerebellar gangliocytoma) is a rare disorder of unknown pathogenesis, presenting with signs and symptoms resulting from obstruction of cerebrospinal fluid flow and mass effect in the posterior fossa. Magnetic resonance imaging is the diagnostic modality of choice allowing preoperative diagnosis with characteristic(More)
