Abstract
Sickle Cell Disease (SCD) is a severe genetic disorder causing vascular occlusion and pain by upregulating the adhesion molecule P-selectin on endothelial cells and platelets. It primarily affects infants and children, causing chronic pain, circulatory problems, organ damage, and complications. Thus, effective treatment and management are crucial to reduce SCD-related risks. Anti-P-selectin antibody Crizanlizumab (Crimab) has been used to treat SCD. In this study, the heavy and light chain (HC and LC) genes of anti-P-Selectin antibody Crimab were cloned into a plant expression binary vector. The HC gene was under control of the duplicated 35S promoter and nopaline synthase (NOS) terminator, whereas the LC gene was under control of the potato proteinase inhibitor II (PIN2) promoter and PIN2 terminator. Agrobacterium tumefaciens LBA4404 was used to transfer the genes into the tobacco (Nicotiana tabacum cv. Xanthi) plant. In plants the genomic PCR and western blot confirmed gene presence and expression of HC and LC Crimab proteins in the plant, respectively. Crimab was successfully purified from transgenic plant leaf using protein A affinity chromatography. In ELISA, plant-derived Crimab (CrimabP) had similar binding activity to P-selectin compared to mammalian-derived Crimab (CrimabM). In surface plasmon resonance, the KD (dissociation binding constant) and response unit values were lower and higher than CrimabP, respectively. Taken together, these results demonstrate that the transgenic plant can be applied to produce biofunctional therapeutic monoclonal antibody.

Abstract
MAIN CONCLUSION LSC CO17-1AK and anti-HER2 VHH-FcK can be produced in a single plant and exhibit anti-tumor activities comparable to those of their respective parent antibodies. Recombinant monoclonal antibodies (mAbs) which can be applied to treat various cancers, are primarily produced using mammalian, insect, and bacteria cell culture systems. Plant expression systems have also been developed to produce antibodies. Plant expression systems present several advantages, including a lack of human pathogenic agents, efficient production costs, and easy large-scale production. In this study, we generated a transgenic plant expressing anti-colorectal cancer large single chain (LSC) CO17-1AK and anti-human epidermal growth factor receptor 2 (HER2) VHH-FcK mAbs by cross-pollinating plants expressing LSC CO17-1AK and anti-HER2 VHH-FcK, respectively. F1 siblings expressing both LSC CO17-1AK and anti-HER2 VHH-FcK were screened using polymerase chain reaction and Western-blot analyses. The cell enzyme-linked immunosorbent assay (Cell ELISA) confirmed the binding of LSC CO17-1AK and anti-HER2 VHH-FcK to target proteins in the SW620 human colorectal cancer and the SKBR-3 human breast cancer cell lines, respectively. The wound healing assay confirmed the inhibitory activity of both antibodies against SW620 and SKBR-3 cell migration, respectively. In conclusion, both LSC CO17-1AK mAb and anti-HER2 VHH-FcK can be produced in a single plant, achieve binding activities to SW620 and SKBR-3 cancer cells, and inhibitory activity against SW620 and SKBR-3 cell migration similar to their parental antibodies, respectively.

Co-transient expression of PSA-Fc and PAP-Fc fusion protein in plant as prostate cancer vaccine candidates and immune responses in mice. PLANT CELL REPORTS 2023; 42:1203-1215.

Abstract
KEY MESSAGE PAP-FcK and PSA-FcK prostate cancer antigenic proteins transiently co-expressed in plant induce their specific humoral immune responses in mice. Prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) have been considered as immunotherapeutic antigens for prostate cancer. The use of a single antigenic agent is unlikely to be effective in eliciting immunotherapeutic responses due to the heterogeneous and multifocal nature of prostate cancer. Thus, multiple antigens have been combined to enhance their anti-cancer effects. In the current study, PSA and PAP were fused to the crystallizable region (Fc region) of immunoglobulin G1 and tagged with KDEL, the endoplasmic reticulum (ER) retention signal motif, to generate PSA-FcK and PAP-FcK, respectively, and were transiently co-expressed in Nicotiana benthamiana. Western blot analysis confirmed the co-expression of PSA-FcK and PAP-FcK (PSA-FcK + PAP-FcK) with a 1:3 ratios in the co-infiltrated plants. PSA-FcK, PAP-FcK, and PSA-FcK + PAP-FcK proteins were successfully purified from N. benthamiana by protein A affinity chromatography. ELISA showed that anti-PAP and anti-PSA antibodies successfully detected PAP-FcK and PSA-FcK, respectively, and both detected PSA-FcK + PAP-FcK. Surface plasmon resonance (SPR) analysis confirmed the binding affinity of the plant-derived Fc fusion proteins to FcγRI/CD64. Furthermore, we also confirmed that mice injected with PSA-FcK + PAP-FcK produced both PSA- and PAP-specific IgGs, demonstrating their immunogenicity. This study suggested that the transient plant expression system can be applied to produce the dual-antigen Fc fusion protein (PSA-FcK + PAP-FcK) for prostate cancer immunotherapy.

Abstract
Abstract
Transgenic plants expressing immunoglobulin (Ig) M Fc-fused Prostate acid phosphatase (PAP) antigenic proteins (PAP-IgM FcK) and J-chain proteins were generated by Agrobacterium-mediated transformation. The Fc region was tagged with the ER retention motif (KDEL) to make PAP-IgM FcK. Two transgenic plants were crossed together to generate F1 expressing both PAP-IgM FcK and J-chain proteins (PAP-IgM FcK × J-chain). PCR and RT-PCR analyses confirmed the transgene insertion and mRNA transcription of PAP-IgM FcK and J-chain in leaf tissue of PAP-IgM FcK × J-chain F1 plant. Western blot confirmed the expression of PAP-IgM FcK × J-chain protein. Size exclusion (SEC)-high performance liquid chromatography (HPLC) and Bio-transmission electron microscope (TEM) analyses were performed to show the size and shape of the PAP- IgM FcK × J-chain fusion proteins. These results suggest that PAP-IgM FcK with J-chain can be produced in plant expression system with plant crossing.

KDEL Receptors: Pathophysiological Functions, Therapeutic Options, and Biotechnological Opportunities. Biomedicines 2022; 10:biomedicines10061234.

Abstract
KDEL receptors (KDELRs) are ubiquitous seven-transmembrane domain proteins encoded by three mammalian genes. They bind to and retro-transport endoplasmic reticulum (ER)-resident proteins with a C-terminal Lys-Asp-Glu-Leu (KDEL) sequence or variants thereof. In doing this, KDELR participates in the ER quality control of newly synthesized proteins and the unfolded protein response. The binding of KDEL proteins to KDELR initiates signaling cascades involving three alpha subunits of heterotrimeric G proteins, Src family kinases, protein kinases A (PKAs), and mitogen-activated protein kinases (MAPKs). These signaling pathways coordinate membrane trafficking flows between secretory compartments and control the degradation of the extracellular matrix (ECM), an important step in cancer progression. Considering the basic cellular functions performed by KDELRs, their association with various diseases is not surprising. KDELR mutants unable to bind the collagen-specific chaperon heat-shock protein 47 (HSP47) cause the osteogenesis imperfecta. Moreover, the overexpression of KDELRs appears to be linked to neurodegenerative diseases that share pathological ER-stress and activation of the unfolded protein response (UPR). Even immune function requires a functional KDELR1, as its mutants reduce the number of T lymphocytes and impair antiviral immunity. Several studies have also brought to light the exploitation of the shuttle activity of KDELR during the intoxication and maturation/exit of viral particles. Based on the above, KDELRs can be considered potential targets for the development of novel therapeutic strategies for a variety of diseases involving proteostasis disruption, cancer progression, and infectious disease. However, no drugs targeting KDELR functions are available to date; rather, KDELR has been leveraged to deliver drugs efficiently into cells or improve antigen presentation.

Effect of an Endoplasmic Reticulum Retention Signal Tagged to Human Anti-Rabies mAb SO57 on Its Expression in Arabidopsis and Plant Growth. Mol Cells 2021; 44:770-779. [PMID: 34711693 PMCID: PMC8560589 DOI: 10.14348/molcells.2021.2002] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2020] [Revised: 08/20/2021] [Accepted: 08/27/2021] [Indexed: 11/30/2022] Open
Abstract
Transgenic Arabidopsis thaliana expressing an anti-rabies monoclonal antibody (mAb), SO57, was obtained using Agrobacterium-mediated floral dip transformation. The endoplasmic reticulum (ER) retention signal Lys-Asp-Glu-Leu (KDEL) was tagged to the C-terminus of the anti-rabies mAb heavy chain to localize the mAb to the ER and enhance its accumulation. When the inaccurately folded proteins accumulated in the ER exceed its storage capacity, it results in stress that can affect plant development and growth. We generated T1 transformants and obtained homozygous T3 seeds from transgenic Arabidopsis to investigate the effect of KDEL on plant growth. The germination rate did not significantly differ between plants expressing mAb SO57 without KDEL (SO plant) and mAb SO57 with KDEL (SOK plant). The primary roots of SOK agar media grown plants were slightly shorter than those of SO plants. Transcriptomic analysis showed that expression of all 11 ER stress-related genes were not significantly changed in SOK plants relative to SO plants. SOK plants showed approximately three-fold higher mAb expression levels than those of SO plants. Consequently, the purified mAb amount per unit of SOK plant biomass was approximately three times higher than that of SO plants. A neutralization assay revealed that both plants exhibited efficient rapid fluorescent focus inhibition test values against the rabies virus relative to commercially available human rabies immunoglobulins. KDEL did not upregulate ER stress-related genes; therefore, the enhanced production of the mAb did not affect plant growth. Thus, KDEL fusion is recommended for enhancing mAb production in plant systems.

Abstract
Gaucher disease is an inherited lysosomal storage disorder caused by a deficiency of functional enzyme β-glucocerebrosidase (GCase). Recombinant GCase has been used in enzyme replacement therapy to treat Gaucher disease. Importantly, the terminal mannose N-glycan structure is essential for the uptake of recombinant GCase into macrophages via the mannose receptor. In this research, recombinant GCase was produced using Agrobacterium-mediated transient expression in both wild-type (WT) and N-acetylglucosaminyltransferase I (GnTI) downregulated Nicotiana benthamiana (ΔgntI) plants, the latter of which accumulates mannosidic-type N-glycan structures. The successfully produced functional GCase exhibited GCase enzyme activity. The enzyme activity was the same as that of the conventional mammalian-derived GCase. Notably, N-glycan analysis revealed that a mannosidic-type N-glycan structure lacking plant-specific N-glycans (β1,2-xylose and α1,3-fucose residues) was predominant in all glycosylation sites of purified GCase produced from ΔgntI plants. Our research provides a promising alternative plant line as a host for the production of recombinant GCase with a mannosidic-type N-glycan structure. This glycoengineered plant might be applicable to the production of other pharmaceutical proteins, especially mannose receptor targeted protein, for therapeutic uses.
