Abstract
Interferons (IFNs) are divided into 3 types (type I, type II, and type III) on the basis of sequence homology and functional properties. Recombinant IFNs have been approved by regulatory agencies in many countries for clinical treatment of hepatitis B, hepatitis C, and other diseases; these IFNs are mainly produced in microorganisms and mammalian cell systems. However, there are serious obstacles to the production of recombinant IFNs in microorganism systems; for example, the recombinant IFN may have different glycosylation patterns from the native protein, be present in insoluble inclusion bodies, be contaminated with impurities such as endotoxins and nucleic acids, have a short half-life in human blood, and incur high production costs. Some medicinal proteins have been successfully expressed in plants and used in clinical applications, suggesting that plants may also be a good system for IFN expression. However, there are still many technical problems that need to be addressed before the clinical application of plant-expressed IFNs, such as increasing the amount of recombinant protein expression and ensuring that the IFN is modified with the correct type of glycosylation. In this article, we review the classification of IFNs, their roles in antiviral signal transduction pathways, their clinical applications, and their expression in plant systems.

A De Novo Optimized Cell-Free System for the Expression of Soluble and Active Human Tumor Necrosis Factor-Alpha. BIOLOGY 2022; 11:biology11020157. [PMID: 35205024 PMCID: PMC8868817 DOI: 10.3390/biology11020157] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 01/14/2022] [Accepted: 01/17/2022] [Indexed: 11/27/2022]
Abstract
Simple Summary As a result of increasing demand for the pleiotropic cytokine TNF-α, recombinant human TNF-α protein with appropriate bioactivities was produced in several heterologous in vivo expression systems. While in vivo expression of this cytokine is laborious and lengthy, cell-free or in vitro expression system has the benefits of speed, simplicity, flexibility, focus of all the system energy on target protein synthesis alone, besides high soluble and functional protein yield. Therefore, we employed and optimized an E. coli-based cell-free system for the first time to express recombinant human TNF-α. Our findings revealed that cell-free expression system can be an alternative platform for producing soluble and functionally active recombinant TNF-α with a yield of 390 µg/mL in only 2 h at a temperature of 40 °C for further research and clinical trials. Abstract Cell-free (in vitro) expression is a robust alternative platform to the cell-based (in vivo) system for recombinant protein production. Tumor necrosis factor-alpha (TNF-α) is an effective pro-inflammatory cytokine with pleiotropic effects. The aim of the current study was de novo optimized expression of soluble and active human TNF-α by an in vitro method in an E. coli-based cell-free protein synthesis (CFPS) system and its biological activity evaluation. The codon-optimized synthetic human TNF-α gene was constructed by a two-step PCR, cloned into pET101/D-TOPO vector and then expressed by the E. coli CFPS system. Cell-free expression of the soluble protein was optimized using a response surface methodology (RSM). The anticancer activity of purified human TNF-α was assessed against three human cancer cell lines: Caco-2, HepG-2 and MCF-7. Data from RSM revealed that the lowest value (7.2 µg/mL) of cell-free production of recombinant human TNF-α (rhTNF-α) was obtained at a certain incubation time (6 h) and incubation temperature (20 °C), while the highest value (350 µg/mL) was recorded at 4 h and 35 °C. This rhTNF-α showed a significant anticancer potency. Our findings suggest a cell-free expression system as an alternative platform for producing soluble and functionally active recombinant TNF-α for further research and clinical trials.

Biotechnol J 2021; 16:e2100143.

Abstract
BACKGROUND Lactose-based induction strategy in E. coli cultivation has several advantages over IPTG as it is cheap, does not impart metabolic stress to cells, and is non-toxic to cells. However, complexity of lactose as an inducer limits its application in fed-batch cultivation. A mixed glycerol-lactose based induction strategy is generally opted during fed-batch cultivation of E. coli. However, slow growth of E. coli in glycerol and lactose results in slower induction of heterologous protein. MAIN METHODS AND MAJOR RESULTS In this study, initially we have demonstrated supplementation of critical amino acids (AAs) improves uptake rate of glycerol and lactose in wildtype E. coli BL21(DE3) in defined medium. A feeding strategy of mixed glycerol-lactose feed along with supplement of critical AAs enhances recombinant production of pramlintide multimer (rPramlintide). High cell density cultivation of E. coli using mixed glycerol-lactose feed and critical AAs supplement resulted in final cell density of 52.2 ± 0.90 g L-1 and rPramlintide titer of 7.8 g L-1 . RT-qPCR analysis of genes involved in glycerol and lactose metabolism of recombinant culture showed upregulation with AAs supplementation. CONCLUSIONS AND IMPLICATIONS We hypothesize that supplementation of critical AAs serves dual purpose: (i) faster assimilation of carbon sources, and (ii) combating metabolic stress arises due to AAs starvation. The substrate uptake and gene expression profiles demonstrate that AAs addition enhances glycerol and lactose assimilation due to overall improvement in their metabolism governed by global regulators of carbon metabolism.

Strategies for the Production of Soluble Interferon-Alpha Consensus and Potential Application in Arboviruses and SARS-CoV-2. Life (Basel) 2021; 11:life11060460.

Abstract
Biopharmaceutical production is currently a multibillion-dollar industry with high growth perspectives. The research and development of biologically sourced pharmaceuticals are extremely important and a reality in our current healthcare system. Interferon alpha consensus (cIFN) is a non-natural synthetic antiviral molecule that comprises all the most prevalent amino acids of IFN-α into one consensus protein sequence. For clinical use, cIFN is produced in E. coli in the form of inclusion bodies. Here, we describe the use of two solubility tags (Fh8 and DsbC) to improve soluble cIFN production. Furthermore, we analyzed cIFN production in different culture media and temperatures in order to improve biopharmaceutical production. Our results demonstrate that Fh8-cIFN yield was improved when bacteria were cultivated in autoinduction culture medium at 30 °C. After hydrolysis, the recovery of soluble untagged cIFN was 58% from purified Fh8-cIFN molecule, fourfold higher when compared to cIFN recovered from the DsbC-cIFN, which achieved 14% recovery. The biological activity of cIFN was tested on in vitro model of antiviral effect against Zika, Mayaro, Chikungunya and SARS-CoV-2 virus infection in susceptible VERO cells. We show, for the first time, that cIFN has a potent activity against these viruses, being very low amounts of the molecule sufficient to inhibit virus multiplication. Thus, this molecule could be used in a clinical approach to treat Arboviruses and SARS-CoV-2.

Abstract
The human hCLCA1 gene is a member of the CLCA gene family that has a well-documented role in inflammatory airway diseases. Previously, we demonstrated that secreted hCLCA1 plays a role in regulating the innate immune response by activating airway macrophages. However, the mechanism of this regulation remains unclear. In this present study, recombinant proteins containing different hCLCA1 domains are expressed to determine the specific hCLCA1 domain(s) responsible for macrophage activation. Specifically, hCLCA1 constructs containing the hydrolase domain (HYD), the von Willebrand Factor Type A (VWA) domain, and the fibronectin type III (FN3) domain were heterologously expressed and affinity purified through fast protein liquid chromatography. Circular dichroism spectroscopy revealed that the purified hCLCA1 constructs exhibited secondary structure consistent with folded proteins. The VWA domain clearly demonstrated an ability to activate macrophages, inducing an increase in both IL-1β mRNA and protein expression. This activation was associated with the activation of MAPKs and NF-κB pathways, identifying potential mechanistic pathways by which hCLCA1's VWA domain exerts its signaling effect. Altogether, this work identifies a domain with signaling function within hCLCA1, providing a specific target to one of the most highly induced gene products of airway inflammatory disease.

Abstract
The Escherichia coli phosphoglucose isomerase (pgi) mutant strain GALG20 was developed previously from wild-type K12 strain MG1655 for increased plasmid yield. To investigate the potential effects of the pgi deletion/higher plasmid levels on recombinant human Interferon Gamma (IFN-γ) production, a detailed network of the central metabolic pathway (100 metabolites, 114 reactions) of GALG20 and MG1655 was constructed. Elementary mode analysis (EMA) was then performed to compare the phenotypic spaces of both the strains and to check the effect of the pgi deletion on flux efficiency of each metabolic reaction. The results suggested that pgi deletion increases amino acid biosynthesis and flux efficiency towards IFN-γ synthesis by 11%. To further confirm the qualitative prediction that the pgi mutation favours recombinant human IFN-γ expression, GALG20 and MG1655 were lysogenised, transformed with a plasmid coding for IFN-γ and tested alongside with BL21(DE3) for their expression capabilities in shake flask experiments using complex media. IFN-γ gene expression was analysed by quantifying plasmid and mRNA copy number per cell and IFN-γ protein production level. Specific IFN-γ yields confirmed the in silico metabolic network predictions, with GALG20(DE3) producing 3.0-fold and 1.5-fold more IFN-γ as compared to MG1655(DE3) and BL21(DE3), respectively. Most of the total IFN-γ was expressed as inclusion bodies across the three strains: 95% in GALG20(DE3), 97% in BL21(DE3) and 72% in MG1655(DE3). The copy number of mRNA coding for IFN-γ was found to be higher in GALG20(DE3) as compared to the other two strains. Overall, these findings show that GALG20(DE3) has the potential to become an excellent protein expression strain.

Abstract
A myc-tag and of which recognition by an antibody 9E10 has long been used for the detection and purification of recombinant proteins. We have previously expanded the application of the tag to the specific detection and purification of backbone-cyclized proteins. Here we sought a more practical way to using the 9E10 antibody by expressing its single chain antibody (scAb) form in Escherichia coli. The combined use of a strong T7 promoter and auto-induction strategy rather than early to mid-log induction of a Lac promoter resulted in the soluble over-expression of 9E10 scAb. However, the co-expression of a chaperone, Skp, was absolutely necessary for the activity even when the protein was expressed in a soluble manner. We could purify about 4 mg of 9E10 scAb from 1 l of culture, and the resulting scAb could be used to detect and purify the backbone-cyclized protein as the parental full-length 9E10. Moreover, the immunoaffinity resin prepared using 9E10 scAb could be regenerated several times after the elution of bound proteins using an acid, which added more value to the ready preparation of the active antibody in bacteria.
