Effect of N-glycosylation on secretion, stability, and biological activity of recombinant human interleukin-3 (hIL-3) in Pichia pastoris. 3 Biotech 2022; 12:221.

Abstract
Human interleukin-3 (hIL-3) is a clinically important cytokine used to treat hematological malignancies, bone marrow transplantation, cytopenias, and immunological disorders. The cloning of hIL-3 gene was previously reported by our group, where its expression was optimized under methanol-inducible AOX1 promoter having N-terminal α mating factor signal sequence from Saccharomyces cerevisiae. This study investigated the role of glycosylation pattern on its molecular stability, secretion efficiency, and biological activity using the mutagenesis approach. The two N-linked glycosylation positions at N15th (Asn15) and N70th (Asn70) were sequentially mutated to generate three recombinant hIL-3 variants, i.e., N15A, N70A, and N15/70A. Asparagine at these positions was replaced with non-polar alanine amino acid (Ala, A). The alteration of N-linked glycosylation sites was disadvantageous to its efficient secretion in Pichia pastoris, where a 52.32%, 36.48%, 71.41% lower production was observed in N15A, N70A, and N15/70A mutants, respectively, as compared to native control. The fully glycosylated native hIL-3 protein showed higher thermal stability over its deglycosylated counterparts. The biological activity of native, N15A, N70A, and N15/70A hIL-3 protein was evaluated, where N15/70A mutant showed slightly higher proliferation efficacy than other combinations.

Abstract
Cytokines consist of peptides, proteins and glycoproteins, which are biological signaling molecules, and boost cell-cell communication in immune reactions to stimulate cellular movements in the place of trauma, inflammation and infection. Recombinant cytokines are designed in such a way that they have generalized immunostimulation action or stimulate specific immune cells when the body encounters immunosuppressive signals from exogenous pathogens or other tumor microenvironments. Recombinant cytokines have improved the treatment processes for numerous diseases. They are also beneficial against novel toxicities that arise due to pharmacologic immunostimulators that lead to an imbalance in the regulation of cytokine. So, the production and use of recombinant human cytokines as therapeutic proteins are significant for medical treatment purposes. For the improved production of recombinant human cytokines, the development of host cells such as bacteria, yeast, fungi, insect, mammal and transgenic plants, and the specific expression systems for individual hosts is necessary. The recent advancements in the field of genetic engineering are beneficial for easy and efficient genetic manipulations for hosts as well as expression cassettes. The use of metabolic engineering and systems biology approaches have tremendous applications in recombinant protein production by generating mathematical models, and analyzing complex biological networks and metabolic pathways via simulations to understand the interconnections between metabolites and genetic behaviors. Further, the bioprocess developments and the optimization of cell culture conditions would enhance recombinant cytokines productivity on large scales.

Abstract
The potential of urate oxidase (uricase) for clinical use has been highlighted because of its role in lowering the blood uric acid levels for the treatment of tumor lysis syndrome. In the present study, the codon-optimized synthetic gene of Aspergillus flavus uricase was fused to the Mxe GyrA intein and chitin-binding domain. The construct was inserted into pPICZA and pPICZαA vectors and electroporated into Pichia pastoris GS115 for the cytosolic and secretory expression. Transformants were screened on gradients of Zeocin up to 2000 μg/ml to find multi-copy integrants. For both constructs, colonies with more resistance were screened for the highest uricase producers by enzyme assay. PCR analysis confirmed successful cassettes insertion into the genome and Mut + phenotype. The gene copy index was determined to be two and five for cytosolic and secretory strains, respectively. Productivity of the cytosolic and secretory strains was found to be 0.74 and 0.001 U/ml culture media in order while the cytosolic recombinant enzyme accounted for about 6% of total proteins. One-step purification of the expressed uricase was done with the aid of the chitin affinity column, followed by DTT induction for intein on-column cleavage. The yield of 40.8 mg/L and K m of 0.22 mM was obtained for intracellular expression. It seems that the intracellular production of uricase can indeed serve as an effective alternative to secretory expression. Moreover, this is the first report considering cytosolic production of uricase using the intein-mediated protein purification in the methylotrophic yeast, P. pastoris.

Molecular characterization of an interleukin-4/13B homolog in grass carp (Ctenopharyngodon idella) and its role in fish against Aeromonas hydrophila infection. FISH & SHELLFISH IMMUNOLOGY 2016; 57:136-147. [PMID: 27546554 DOI: 10.1016/j.fsi.2016.08.022] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/03/2016] [Revised: 08/10/2016] [Accepted: 08/13/2016] [Indexed: 06/06/2023]
Abstract
Mammalian interleukin 4 (IL-4) and interleukin 13 (IL-13) molecules are anti-inflammatory cytokines mediating the alternative activation of macrophages. However, the role of fish IL-4/13 homologs in monocytes/macrophages (MO/MФ) polarization remains unclear. In this study, we have functionally identified an IL-4/13B homolog in grass carp (Ctenopharyngodon idella), which is termed as CiIL-4/13B. Multiple alignment showed that CiIL-4/13B shared the typical characteristics and structure with other known fish IL-4/13. Phylogenetic analysis showed that CiIL-4/13B is evolutionarily closely related to zebrafish (Danio rerio) and common carp (Cyprinus carpio) IL-4/13B. CiIL-4/13B mRNA was constitutively expressed in tissues and peripheral blood lymphocytes (PBLs) examined, with its highest expression seen in PBLs. Following Aeromonas hydrophila infection, CiIL-4/13B mRNA expression was upregulated. Recombinant CiIL-4/13B (rCiIL-4/13B) was overexpressed in Escherichia coli and purified for a functional study. Using prepared anti-rCiIL-4/13B antiserum, Western blot analysis showed that native CiIL-4/13B in grass carp plasma is N-glycosylated. Intraperitoneal injection of bioactive rCiIL-4/13B significantly increased the survival rate of grass carp against A. hydrophila, and decreased the tissue bacterial load, with a higher dose having better effects. Bioactive rCiIL-4/13B treatment decreased nitrite production and mRNA expression of proinflammatory cytokines (IL-1β and TNF-α), while it increased arginase activity and mRNA expression of anti-inflammatory cytokines (TGF-β and IL-10). The phagocytosis by grass carp MO/MФ had no significant changes by the 8 h treatment of bioactive rCiIL-4/13B compared to that of the negative control, while it was significantly inhibited by the 24 h treatment of bioactive rCiIL-4/13B. The inhibitory effect of rCiIL-4/13B on MO/MФ phagocytosis may be a consequence of MO/MФ proliferation. In summary, our results suggest that CiIL-4/13B plays a protective effect in grass carp against A. hydrophila by inducing alternatively activated MO/MФ.

Abstract
Fish have a complex self-defense mechanism against microbial invasion. Recently, l-lysine α-oxidases have been identified from a number of fish species as a novel type of antibacterial protein in the integument. These enzymes exhibit strict substrate specificity for l-lysine, but the underlying mechanisms and details of their catalytic properties remain unknown. In this study, a synthetic gene coding for Scomber japonicus l-lysine α-oxidase, originally termed AIP (for apoptosis-inducing protein), was expressed in Pichia pastoris, and the recombinant enzyme (rAIP) was purified and characterized. rAIP exhibited essentially the same substrate specificity as the native enzyme, catalyzing the oxidative deamination of l-lysine as an exclusive substrate. rAIP was N-glycosylated and remained active over a wide range of pH, with an optimal pH of 7.5. The enzyme was stable in the pH range from 4.5 to 10.0 and was thermally stable up to 60°C. A molecular modelling of rAIP and a comparative structure/sequence analysis with homologous enzymes indicate that Asp(220) and Asp(320) are the substrate-binding residues that are likely to confer exclusive substrate specificity for l-lysine on the fish enzymes.
