Little is known about the dynamics of cancer cell death in response to therapy in the tumor microenvironment. Intravital microscopy of chemotherapy-treated mouse mammary carcinomas allowed us to follow drug distribution, cell death, and tumor-stroma interactions. We observed associations between vascular leakage and response to doxorubicin, including(More)
Sons and daughters (ages 8-14) of male alcoholics without psychiatric problems were compared with sons and daughters of controls employing two auditory paradigms to elicit event-related potentials (ERPs). All of the children of alcoholics were from high density families (each father had an average of 3.7 first and second-degree relatives meeting criteria(More)
Growth of multiple myeloma cells is controlled by various factors derived from host bone marrow microenvironments. Interaction between multiple myeloma cells and bone marrow stromal cells (BMSCs) plays an important role in the expression of adhesive molecules and secretion of growth factors involved in multiple myeloma (MM) cell growth, survival, and(More)
Human renal cell carcinoma (HRCC) is characterized by a high level of resistance to all treatment modalities. Therefore, the investigation of global gene expression in HRCC might help understand its biologic behavior and develop treatment strategies. Using cDNA microarray analysis, we initially compared gene expression profiles between HRCCs and adjacent(More)
IL-6 and TNF α were significantly increased in the bone marrow aspirate samples of patients with active multiple myeloma (MM) compared to those of normal controls. Furthermore, MM patients with advanced aggressive disease had significantly higher levels of IL-6 and TNF α than those with MM in plateau phase. TNF α increased interleukin-6 (IL-6) production(More)
The transcription factor nuclear factor-kappa B (NF-kappaB) regulates the transcription of a number of genes involved in a variety of cellular responses, including cell survival, inflammation, and differentiation. NF-kappaB is activated by a variety of stimuli, proinflammatory cytokines, mitogens, growth factors, and stress-inducing agents. Aberrant(More)
Although STI571 still plays a key role in the treatment of chronic myeloid leukemia, emergence of resistance to STI571 is a major obstacle to successful outcome. Therefore, new agents that increase the sensitivity of chronic myeloid leukemia cells to STI571 are urgently required. SK-7041 is a novel hybrid synthetic histone deacetylase inhibitor derived from(More)
Bortezomib has been known as the most promising anti-cancer drug for multiple myeloma (MM). However, recent studies reported that not all MM patients respond to bortezomib. To overcome such a stumbling-block, studies are needed to clarify the mechanisms of bortezomib resistance. In this study, we established a bortezomib-resistant cell line (U266/velR), and(More)
Mutations of nucleophosmin gene (NPM1) are known to be related to good prognosis in AML patients lacking FLT3 internal tandem duplication (FLT3-ITD). Recently, NPM1 mutations other than type A were reported, but their clinical significance is not well known. Retrospective medical record review of 106 de novo AML patients lacking FLT3-ITD, who received(More)
To characterize the molecular mechanisms involved in the transition from the chronic phase to blast crisis in chronic myelogenous leukemia (CML), gene expression profiles of leukemic cells from patients in the chronic and blast crisis phases were analyzed using an 8.7K cDNA chip and real-time PCR. A transient transfection analysis was conducted to evaluate(More)
