Therapeutic efficacy of plant-produced Nivolumab in transgenic C57BL/6-hPD-1 mouse implanted with MC38 colon cancer.

ABSTRACT: The therapeutic blockade of inhibitory PD-1 signaling has emerged as an effective approach for cancer immunotherapy. Nivolumab (Opdivo®), a monoclonal antibody (mAb) targeting the PD-1 immune checkpoint, is approved for treatment of several cancer indications. It functions by blocking the PD-1-mediated T-cell inhibition thus reinstating anticancer immune responses. Tremendous advances in plant biotechnology offer an alternative and economical strategy to produce therapeutic mAbs for immune-based therapies. In this study, recombinant anti-PD-1 Nivolumab was produced in Nicotiana benthamiana and the plant-produced anti-PD-1 mAb was exploited for cancer treatment in syngeneic mice model C57BL/6 mice that were used to test the antitumor efficacy of plant produced Nivolumab, along with commercial Opdivo®. C57BL/6 syngeneic mice treated with plant produced anti-PD-1 mAb exhibited reduction in the growth of established MC38 tumors. The plant produced Nivolumab treatment showed 82.9% antitumor effect in decreasing the tumor volume along with 50% tumor-free mice, whereas Opdivo® showed 90.26% reduction in volume without any tumor-free mice. Finally, plant-derived anti-PD-1 therapy was also well tolerated in tumor-bearing mice that correlated with no significant body weight changes. Overall, our plant-produced Nivolumab elicits significant inhibition of tumor growth in vivo and provides a proof-of-concept for the production of immunotherapy targeting PD-1.

Project description:The common experimental use of B16-F10 melanoma cells focuses on exploring their metastatic potential following intravenous injection into mice. In this study, B16-F10 cells are used to develop a primary tumor model by implanting them directly into the ears of C57BL/6J mice. The model represents a reproducible and easily traceable tool for local tumor growth and for making additional in vivo observations, due to the localization of the tumors. This model is relatively simple and involves (i) surgical opening of the ear skin, (ii) removal of a square-piece of cartilage followed by (iii) the implantation of tumor cells with fibrin gel. The remodeling of the fibrin gel within the cartilage chamber, accompanying tumor proliferation, results in the formation of blood vessels, lymphatics and tissue matrix that can be readily distinguished from the pre-existing skin structures. Moreover, this method avoids the injection-enforced artificial spread of cells into the pre-existing lymphatic vessels. The tumors have a highly reproducible exponential growth pattern with a tumor doubling time of around 1.8 days, reaching an average volume of 85mm3 16 days after implantation. The melanomas are densely cellular with proliferative indices of between 60 and 80%. The induced angiogenesis and lymphangiogenesis resulted in the development of well-vascularized tumors. Different populations of immunologically active cells were also present in the tumor; the population of macrophages decreases with time while the population of T cells remained quasi constant. The B16-F10 tumors in the ear frequently metastasized to the cervical lymph nodes, reaching an incidence of 75% by day 16. This newly introduced B16-F10 melanoma model in the ear is a powerful tool that provides a new opportunity to study the local tumor growth and metastasis, the associated angiogenesis, lymphangiogenesis and tumor immune responses. It could potentially be used to test different treatment strategies.

Project description:Colorectal cancer (CRC) is one of the most deaths causing diseases worldwide. Several risk factors including hormones like insulin and insulin like growth factors (e.g., IGF-1) have been considered responsible for growth and progression of colon cancer. Though there is a huge advancement in the available screening as well as treatment techniques for CRC. There is no significant decrease in the mortality of cancer patients. Moreover, the current treatment approaches for CRC are associated with serious challenges like drug resistance and cancer re-growth. Given the severity of the disease, there is an urgent need for novel therapeutic agents with ideal characteristics. Several pieces of evidence suggested that natural products, specifically medicinal plants, and derived phytochemicals may serve as potential sources for novel drug discovery for various diseases including cancer. On the other hand, cancer cells like colon cancer require a high basal level of reactive oxygen species (ROS) to maintain its own cellular functions. However, excess production of intracellular ROS leads to cancer cell death via disturbing cellular redox homeostasis. Therefore, medicinal plants and derived phytocompounds that can enhance the intracellular ROS and induce apoptotic cell death in cancer cells via modulating various molecular targets including IGF-1 could be potential therapeutic agents. Alkaloids form a major class of such phytoconstituents that can play a key role in cancer prevention. Moreover, several preclinical and clinical studies have also evidenced that these compounds show potent anti-colon cancer effects and exhibit negligible toxicity towards the normal cells. Hence, the present evidence-based study aimed to provide an update on various alkaloids that have been reported to induce ROS-mediated apoptosis in colon cancer cells via targeting various cellular components including hormones and growth factors, which play a role in metastasis, angiogenesis, proliferation, and invasion. This study also provides an individual account on each such alkaloid that underwent clinical trials either alone or in combination with other clinical drugs. In addition, various classes of phytochemicals that induce ROS-mediated cell death in different kinds of cancers including colon cancer are discussed.
