This book was released on 2017-03-20 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carcinoembryonic antigen (CEA), one of the onco-fetal proteins, is a cell surface glycoprotein, with a high molecular mass of 150-300 kDa. It is normally expressed in the early embryonic development and tends to disappear with the onset of differentiation of fetal tissue into adult ones. CEA has been studied extensively in ovarian cancer and has been reported to be elevated in 30-65% of epithelial tumors, mainly in patients with advanced stage disease. This antigen has been shown not to correlate well with status of disease.

Available in PDF, EPUB and Kindle. Book excerpt: Protective antigen (PA). the pore-forming component of anthrax toxin, has emerged as a platform for the development of cancer therapies because of its versatility and robust ability to translocate proteins into a cell's cytosol. More recently, development of new techniques for modifying PA is enabling it to be retargeted to receptors of interest via fusion with existing protein binders. There is a vast library of potential binders for PA based on natural or novel protein scaffolds generated by the field of protein engineering. This has allowed new approaches for tumor cells to be targeted for cytosolic delivery of toxins as a therapeutic strategy. In our work, we sought to leverage the anti-tumor properties of an antibody, Elv3, to retarget PA to epidermal growth factor receptor (EGFR). This PA construct was shown to be capable of translocating a recently discovered protease, Ras and RapI Specific Protease (RRSP), which cleaves and inactivates the signal effector, Ras, found in the cytosol. We demonstrated that when Ras is inhibited in this manner, downstream growth signaling through pERK is ablated and health of a pancreatic cancer cell line (AsPC-l) is affected. Our results suggest that this retargeted PA, rnPA-Elv3, efficiently translocates cytotoxic material into EGFR-positive tumor cells and thus presents a possible avenue for development of a potent therapeutic. Using the same approach, we also took another previously engineered antibody, sm3e and expressed it as a fusion to PA to confer specificity to carcinoembryonic antigen (CEA). Though CEA is not typically internalized, we demonstrated that this retargeted PA (mPA-sm3e) retained the property of endocytosis and translocation and was able to deliver toxins to inhibit proliferation of AsPC-1 tumor cells. Finally, the retargeted PA variants, mPA-Elv3 and mPA-sm3e, were further characterized for tumor growth inhibition using mouse models. Nude mice were treated with the engineered PA variants against EGFR and CEA to test delivery of toxins into the cells of subcutaneous tumors. Initial results were promising, and future work should be aimed at additional studies confirming this work in mouse models. Our work has demonstrated that protein engineering can be used to retarget PA against tumor cells with positive results. We believe that the modularity and versatility of this retargeting strategy holds great potential in the design of anti-cancer therapeutics.

Download or read book Antigen and Antibody Molecular Engineering in Breast Cancer Diagnosis and Treatment written by Roberto L. Ceriani and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, advances in the area of immunology and breast cancer are made at an increasing rate, yielding an amount of information that can become unwieldy. The opportunity for scientists in this area of research to gather together to exchange results and working hypotheses represents, in my belief, a very attractive proposition. With this in mind, these workshops have been convened with two year intervals for the last ten years. In each of them, selected topics have been highlighted. The present workshop underscores the large advancements made in the molecular biology of both breast cancer associated antigens and their corresponding antibodies. Understanding the genetic information for the expression of these antigens has been recently advanced leading to preparation of molecularly engineered reagents for use in vaccination, serum assays, and immunizations for novel antibody production. In the anti-breast cancer antibody field the availability of molecular engineering approaches to humanize murine antibodies has induced intense interest in the creation of less immunogenic antibody forms that are now available for clinical testing. Clinical studies using anti-breast murine antibody continue to be carried out and are presented at this meeting establishing a base line for safety and efficaciousness in imaging and immunotherapy that it is hoped will be superseded by the humanized forms. Basic immunology and immunochemistry studies in breast cancer are also included in this workshop that demonstrate the fast pace at which this research is advancing in many laboratories worldwide.

Download or read book Monoclonal Antibody Production written by National Research Council and published by National Academies Press. This book was released on 1999-05-06 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American Anti-Vivisection Society (AAVS) petitioned the National Institutes of Health (NIH) on April 23, 1997, to prohibit the use of animals in the production of mAb. On September 18, 1997, NIH declined to prohibit the use of mice in mAb production, stating that "the ascites method of mAb production is scientifically appropriate for some research projects and cannot be replaced." On March 26, 1998, AAVS submitted a second petition, stating that "NIH failed to provide valid scientific reasons for not supporting a proposed ban." The office of the NIH director asked the National Research Council to conduct a study of methods of producing mAb. In response to that request, the Research Council appointed the Committee on Methods of Producing Monoclonal Antibodies, to act on behalf of the Institute for Laboratory Animal Research of the Commission on Life Sciences, to conduct the study. The 11 expert members of the committee had extensive experience in biomedical research, laboratory animal medicine, animal welfare, pain research, and patient advocacy (Appendix B). The committee was asked to determine whether there was a scientific necessity for the mouse ascites method; if so, whether the method caused pain or distress; and, if so, what could be done to minimize the pain or distress. The committee was also asked to comment on available in vitro methods; to suggest what acceptable scientific rationale, if any, there was for using the mouse ascites method; and to identify regulatory requirements for the continued use of the mouse ascites method. The committee held an open data-gathering meeting during which its members summarized data bearing on those questions. A 1-day workshop (Appendix A) was attended by 34 participants, 14 of whom made formal presentations. A second meeting was held to finalize the report. The present report was written on the basis of information in the literature and information presented at the meeting and the workshop.
