Chaetocin, a thiodioxopiperazine natural product previously unreported to have anticancer effects, was found to have potent antimyeloma activity in IL-6-dependent and -independent myeloma cell lines in freshly collected sorted and unsorted patient CD138(+) myeloma cells and in vivo. Chaetocin largely spares matched normal CD138(-) patient bone marrow(More)
PURPOSE The phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin (mTOR) pathway and the heat shock protein family are up-regulated in multiple myeloma and are both regulators of the cyclin D/retinoblastoma pathway, a critical pathway in multiple myeloma. Inhibitors of mTOR and HSP90 protein have showed in vitro and in vivo single-agent activity(More)
PURPOSE 2-Methoxyestradiol (2ME2), a natural endogenous product of estradiol metabolism, has demonstrated activity against tumor cell lines and can inhibit angiogenesis. There are limited treatment options for patients with multiple myeloma (MM) who relapse after high-dose therapy and stem cell transplantation. We studied the preclinical activity of 2ME2 as(More)
Phenylacetate (PA) and phenylbutyrate (PB) are aromatic fatty acids that are presently undergoing evaluation as potential antineoplastic agents. In vitro, PA and PB cause differentiation or growth inhibition of malignant cells. Clinical trials of these drugs as single agents indicate that they are not myelosuppressive; therefore, combinations with other(More)
To better understand the molecular changes that occur in Waldenstrom macroglobulinemia (WM), we employed antibody-based protein microarrays to compare patterns of protein expression between untreated WM and normal bone marrow controls. Protein expression was defined as a >2-fold or 1.3-fold change in at least 67% of the tumor samples. Proteins up-regulated(More)
W e read with great interest the article by Harte et al. (1), which reports that high intake of dietary fat results in increased levels of endotoxin in the blood of both type 2 diabetic patients and control subjects, thereby supporting an earlier article by Erridge et al. (2) who studied healthy subjects. Low-grade inflammation is associated with obesity,(More)
