Abstract
Metastatic castration-resistant prostate cancer (PC) is the final stage of PC that acquires resistance to androgen deprivation therapies (ADT). Despite progresses in understanding of disease mechanisms, the specific contribution of the metastatic microenvironment to ADT resistance remains largely unknown. The current study identified that the macrophage is the major microenvironmental component of bone-metastatic PC in patients. Using a novel in vivo model, we demonstrated that macrophages were critical for enzalutamide resistance through induction of a wound-healing-like response of ECM-receptor gene expression. Mechanistically, macrophages drove resistance through cytokine activin A that induced fibronectin (FN1)-integrin alpha 5 (ITGA5)-tyrosine kinase Src (SRC) signaling cascade in PC cells. This novel mechanism was strongly supported by bioinformatics analysis of patient transcriptomics datasets. Furthermore, macrophage depletion or SRC inhibition using a novel specific inhibitor significantly inhibited resistant growth. Together, our findings elucidated a novel mechanism of macrophage-induced anti-androgen resistance of metastatic PC and a promising therapeutic approach to treat this deadly disease.

Abstract
DAB389 IL-2 (Denileukin diftitox) is considered an immunotoxin, and it is the first immunotoxin approved by Food and Drug Administration. It is used for the treatment of a cutaneous form of T-cell lymphoma. This fusion protein has two disulfide bonds in its structure that play an essential role in toxicity and functionality of the immunotoxin. Escherichia coli (E. coli) strain BL21 (DE3) is not capable of making disulfide bonds in its reductive cytoplasm, but the E. coli strain Rosetta-gami (DE3) is a proper strain for the correct expression of the protein due to mutations in glutaredoxin reductase and thioredoxin reductase. In this study, a pET21a vector with the His6-tag fused at the N-terminus of DAB389 IL-2 was used to express the soluble immunotoxin in E. coli Rosetta-gami (DE3). After the purification of the soluble protein by two-step column chromatographies, the structure of DAB389 IL-2 was analyzed using the Native-PAGE and circular dichroism methods. In the following, the nuclease activity of soluble DAB389 IL-2 and its cytotoxicity activity were determined. It is concluded that the soluble recombinant protein expressed in the E. coli Rosetta-gami (DE3) has an intact structure and also functional; hence, this form of immunotoxin could be competitive with its commercial counterparts.

Mechanism of diphtheria toxin catalytic domain delivery to the eukaryotic cell cytosol and the cellular factors that directly participate in the process. Toxins (Basel) 2011; 3:294-308. [PMID: 22069710 PMCID: PMC3202816 DOI: 10.3390/toxins3030294] [Citation(s) in RCA: 104] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2011] [Revised: 03/03/2011] [Accepted: 03/10/2011] [Indexed: 11/17/2022] Open
Abstract
Research on diphtheria and anthrax toxins over the past three decades has culminated in a detailed understanding of their structure function relationships (e.g., catalytic (C), transmembrane (T), and receptor binding (R) domains), as well as the identification of their eukaryotic cell surface receptor, an understanding of the molecular events leading to the receptor-mediated internalization of the toxin into an endosomal compartment, and the pH triggered conformational changes required for pore formation in the vesicle membrane. Recently, a major research effort has been focused on the development of a detailed understanding of the molecular interactions between each of these toxins and eukaryotic cell factors that play an essential role in the efficient translocation of their respective catalytic domains through the trans-endosomal vesicle membrane pore and delivery into the cell cytosol. In this review, I shall focus on recent findings that have led to a more detailed understanding of the mechanism by which the diphtheria toxin catalytic domain is delivered to the eukaryotic cell cytosol. While much work remains, it is becoming increasingly clear that the entry process is facilitated by specific interactions with a number of cellular factors in an ordered sequential fashion. In addition, since diphtheria, anthrax lethal factor and anthrax edema factor all carry multiple coatomer I complex binding motifs and COPI complex has been shown to play an essential role in entry process, it is likely that the initial steps in catalytic domain entry of these divergent toxins follow a common mechanism.

Abstract
Background The stromal microenvironment and particularly the macrophage component of primary tumors influence their malignant potential. However, at the metastatic site the role of these cells and their mechanism of actions for establishment and growth of metastases remain largely unknown. Methodology/Principal Findings Using animal models of breast cancer metastasis, we show that a population of host macrophages displaying a distinct phenotype is recruited to extravasating pulmonary metastatic cells regardless of species of origin. Ablation of this macrophage population through three independent means (genetic and chemical) showed that these macrophages are required for efficient metastatic seeding and growth. Importantly, even after metastatic growth is established, ablation of this macrophage population inhibited subsequent growth. Furthermore, imaging of intact lungs revealed that macrophages are required for efficient tumor cell extravasation. Conclusion/Significance These data indicate a direct enhancement of metastatic growth by macrophages through their effects on tumor cell extravasation, survival and subsequent growth and identifies these cells as a new therapeutic target for treatment of metastatic disease.

Abstract
PURPOSE Hypoxia is a cause for resistance to cancer therapies. Molecularly targeted recombinant cytotoxins have shown clinical efficacy in the treatment of patients with primary brain tumors, glioblastoma multiforme, but it is not known whether hypoxia influences their antitumor effect. EXPERIMENTAL DESIGN We have exposed glioblastoma multiforme cells, such as U-251 MG, U-373 MG, SNB-19, and A-172 MG, to either anoxia or hypoxia and then reoxygenated them while treating with an interleukin (IL)-13-based diphtheria toxin (DT)-containing cytotoxin, DT-IL13QM. We measured the levels of immunoreactive IL-13Ralpha2, a receptor that mediates IL-13-cytotoxin cell killing, and the levels of active form of furin, a protease that activates the bacterial toxin portion in a cytotoxin. RESULTS We found that anoxia/hypoxia significantly alters the responsiveness of glioblastoma multiforme cells to DT-IL13QM. Interestingly, bringing these cells back to normoxia caused them to become even more susceptible to the cytotoxin than the cells maintained under normoxia. Anoxia/hypoxia caused a highly prominent decrease in the immunoreactive levels of both IL-13R and active forms of furin, and reoxygenation not only restored their levels but also became higher than that in normoxic glioblastoma multiforme cells. CONCLUSIONS Our results show that a recombinant cytotoxin directed against glioblastoma multiforme cells kills these cells much less efficiently under anoxic/hypoxic conditions. The reoxygenation brings unexpected additional benefit of making glioblastoma multiforme cells even more responsive to the killing effect of a cytotoxin.

Abstract
Much is known about the structure function relationships of a large number of bacterial protein toxins, the nature of their cell surface receptors, and their enzymatic activities which lead to the inactivation of their respective cytosolic targets. Despite this wealth of knowledge a detailed understanding of the mechanisms which underlie translocation of the catalytic domain across the eukaryotic cell membrane to the cytosol, the penultimate event in the intoxication process, have been slow in developing. In the case of diphtheria toxin, two prominent hypotheses have been advanced to explain how the catalytic domain is translocated from the lumen of endocytic vesicles to the target cell cytosol. We discuss each of these hypotheses and provide an overview of recent observations that tend to favor a mechanism employing a Cytosolic Translocation Factor complex in the entry process. This facilitated mechanism of translocation appears to rely upon protein-protein interactions between conserved domains within the transmembrane domain of diphtheria toxin with host cell factors to effect delivery of the enzymatic moiety. We have recently identified a 10 amino acid motif in the transmembrane domain of diphtheria toxin that is conserved in anthrax Lethal and Edema Factors, as well as in botulinum neurotoxins A, C and D. Stable eukaryotic cell transfectants that express a peptide containing this motif become resistant to the toxin, and sensitivity is completely restored by co-expression of siRNA which inhibits peptide expression. Data obtained from use of the protein fusion toxin DAB(389)IL-2 in cytotoxicity assays using susceptible Hut 102/6TG and resistant transfectant Hut102/6TG-T1 cells, as well as pull down assays have led to the formulation of a working model of facilitated delivery of the diphtheria toxin catalytic domain to the cytosol of target cells which is discussed in detail.

Abstract
There has been recent interest in the depletion of regulatory T cells (Tregs) as part of a multi-faceted approach to the immunotherapy of melanoma patients. This is in part due recent findings that convincingly show that Tregs are an integral part of regulating and even suppressing an immune response to growing tumor cells. We therefore compared three methods of Treg depletion and/or elimination, utilizing low dose cyclophosphamide (CY), a specific antibody directed against the IL-2 receptor found on Tregs (PC61) and the use of denileukin diftitox (DD), which is a fusion protein designed to have a direct cytocidal action on cells which express the IL-2 receptor. We show that CY administration resulted in the highest reduction in Tregs among the three reagents. However, the reduction in Tregs with CY was also associated with the concomitant reduction of CD8(+) T cells and a lack of tumor antigen priming. Utilization of DD resulted in a >50% Treg cell reduction without parallel cytocidal effects upon other T cell subsets but did not enhance anti-tumor immunity against B16 melanoma. Lastly, the PC61 showed a moderate reduction of Tregs that lasted longer than the other reagents, without a reduction in the total number of CD8(+) T cells. Furthermore, PC61 treatment did not abrogate tumor antigen-specific immunity elicited by dendritic cells (DC). We therefore conclude that PC61 administration was the most effective method of reducing Tregs in a murine melanoma model in addition to providing evidence of a synergistic effect when combined with DC-based immunotherapy.
