Thymoglobulin targets multiple plasma cell antigens and has in vitro and in vivo activity in multiple myeloma.
Leukemia 2006 OCT
Abstract
Multiple myeloma is characterized by the proliferation of clonal plasma cells that have a heterogeneous expression of various cell surface markers,precluding successful use of monoclonal antibodies for therapeutic targeting of the tumor cell. Thymoglobulin (rabbit-derived polyclonal anti-thymocyte globulin),by virtue of its method of preparation,contains antibodies against several B-cell and plasma cell antigens and offers an attractive option for immunotherapy of myeloma. Here,we demonstrate potent anti-myeloma activity of the rabbit anti-thymocyte globulin preparation Thymoglobulin in vitro and in vivo in an animal model of myeloma. Thymoglobulin was able to induce dose- and time-dependent apoptosis of several myeloma cell lines,including those resistant to conventional anti-myeloma agents. Importantly,the anti-myeloma activity was preserved even when myeloma cells were grown with different cytokines demonstrating the ability to overcome microenvironment-mediated resistance. Thymoglobulin induced apoptosis of freshly isolated primary myeloma cells from patients. Using a competitive flow cytometric analysis,we were able to identify the potential antigen targets for Thymoglobulin preparation. Finally,in a plasmacytoma mouse model of myeloma,Thymoglobulin delayed the tumor growth in a dose-dependent manner providing convincing evidence for continued evaluation of this agent in the clinic in patients with myeloma,either alone or in combination with other agents.
Chaetocin: a promising new antimyeloma agent with in vitro and in vivo activity mediated via imposition of oxidative stress.
Blood 2007 MAR
Abstract
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 leukocytes,normal B cells,and neoplastic B-CLL (chronic lymphocytic leukemia) cells,indicating a high degree of selectivity even in closely lineage-related B cells. Furthermore,chaetocin displays superior ex vivo antimyeloma activity and selectivity than doxorubicin and dexamethasone,and dexamethasone- or doxorubicin-resistant myeloma cell lines are largely non-cross-resistant to chaetocin. Mechanistically,chaetocin is dramatically accumulated in cancer cells via a process inhibited by glutathione and requiring intact/unreduced disulfides for uptake. Once inside the cell,its anticancer activity appears mediated primarily through the imposition of oxidative stress and consequent apoptosis induction. Moreover,the selective antimyeloma effects of chaetocin appear not to reflect differential intracellular accumulation of chaetocin but,instead,heightened sensitivity of myeloma cells to the cytotoxic effects of imposed oxidative stress. Considered collectively,chaetocin appears to represent a promising agent for further study as a potential antimyeloma therapeutic.
17beta-estradiol downregulates interferon regulatory factor-1 in murine splenocytes.
Journal of molecular endocrinology 2006 DEC
Abstract
Interferon regulatory factor-1 (IRF-1) is an important transcription factor that mediates interferon-gamma (IFN-gamma)-induced cell-signaling events. In this study,we examined whether 17beta-estradiol alters IRF-1 in splenic lymphocytes,in view of the immunomodulatory effects of this natural female sex hormone including its ability to alter IFN-gamma levels. We find that IRF-1 expression is markedly downregulated in splenocytes or purified T-cells from estrogen-treated mice at all time points studied when compared with their placebo counterparts. This decrease in IRF-1 in splenocytes from estrogen-treated mice is neither due to upregulation of IRF-1-interfering proteins (nucleophosmin or signal transducer and activator of transcription (STAT)-5) nor due to alternatively spliced IRF-1 mRNA. Given that IFN-gamma is a potent inducer of IRF-1,direct addition of recombinant IFN-gamma to splenocytes from either wild-type or IFN-gamma-knockout mice,or the addition of recombinant IFN-gamma to purified T-cells,was expected to stimulate IRF-1 expression. However,robust expression of IRF-1 in cells from estrogen-treated mice was not seen,unlike what was observed in cells from placebo-treated mice. Diminished IFN-gamma induction of IRF-1 in cells from estrogen-treated mice was noticed despite comparable phosphorylated STAT-1 activation. These studies are the first to show that estrogen regulates IFN-gamma-inducible IRF-1 in lymphoid cells,a finding that may have implications to IFN-gamma-regulated immune and vascular diseases.
