Targeting delivery of a novel TGF-β type I receptor-mimicking peptide to activated hepatic stellate cells for liver fibrosis therapy via inhibiting the TGF-β1/Smad and p38 MAPK signaling pathways. Eur J Pharmacol 2024; 977:176708. [PMID: 38843945 DOI: 10.1016/j.ejphar.2024.176708] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 06/01/2024] [Accepted: 06/03/2024] [Indexed: 06/23/2024]
Abstract
Excessive transforming growth factor β1 (TGF-β1) secreted by activated hepatic stellate cells (aHSCs) aggravates liver fibrosis via over-activation of TGF-β1-mediated signaling pathways in a TGF-β type I receptor (TβRI) dependent manner. TβRI with the C-terminal valine truncated (RIPΔ), as a novel TβRI-mimicking peptide, is an appealing anti-fibrotic candidate by competitive binding of TGF-β1 to block TGF-β1 signal transduction. Platelet-derived growth factor receptor β (PDGFβR) is highly expressed on the surface of aHSCs in liver fibrosis. Herein, we designed a novel RIPΔ variant Z-RIPΔ (PDGFβR-specific affibody ZPDGFβR fused to the N-terminus of RIPΔ) for liver fibrosis therapy, and expect to improve the anti-liver fibrosis efficacy by specifically inhibiting the TGF-β1 activity in aHSCs. Target peptide Z-RIPΔ was prepared in Escherichia coli by SUMO fusion system. Moreover, Z-RIPΔ specifically bound to TGF-β1-activated aHSCs, inhibited cell proliferation and migration, and reduced the expression of fibrosis markers (α-SMA and FN) and TGF-β1 pathway-related effectors (p-Smad2/3 and p-p38) in vitro. Furthermore, Z-RIPΔ specifically targeted the fibrotic liver, alleviated the liver histopathology, mitigated the fibrosis responses, and blocked TGF-β1-mediated Smad and p38 MAPK cascades. More importantly, Z-RIPΔ exhibited a higher fibrotic liver-targeting capacity and stronger anti-fibrotic effects than its parent RIPΔ. Besides, Z-RIPΔ showed no obvious toxicity effects in treating both an in vitro cell model and an in vivo mouse model of liver fibrosis. In conclusion, Z-RIPΔ represents a promising targeted candidate for liver fibrosis therapy.

[PMID: 37020212 PMCID: PMC10074672 DOI: 10.1186/s12896-023-00779-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 03/28/2023] [Indexed: 04/07/2023] Open
Abstract
BACKGROUND Some peptides are targets for degradation when heterologously expressed as fusion proteins in E. coli, which can limit yields after isolation and purification. We recently reported that peptide degradation may be prevented by production of a "sandwiched" SUMO-peptide-intein (SPI) fusion protein, which protects the target peptide sequence from truncation and improves yield. This initial system required cloning with two commercially available vectors. It used an N-terminal polyhistidine tagged small ubiquitin-like modifier (SUMO) protein and a C-terminal engineered Mycobacterium xenopii DNA Gyrase A intein with an inserted chitin binding domain (CBD) to create "sandwiched" fusion proteins of the form: His6-SUMO-peptide-intein-CBD. However, the major drawback of this previously reported fusion protein "sandwich" approach is the increased time and number of steps required to complete the cloning and isolation procedures, relative to the simple procedures to produce recombinant peptides in E. coli from a single (non-"sandwiched") fusion protein system. RESULTS In this work we generate the plasmid pSPIH6, which improves upon the previous system by encoding both the SUMO and intein proteins and allows facile construction of a SPI protein in a single cloning step. Additionally, the Mxe GyrA intein encoded in pSPIH6 contains a C-terminal polyhistidine tag, resulting in SPI fusion proteins of the form: His6-SUMO-peptide-intein-CBD-His6. The dual polyhistidine tags greatly simplify isolation procedures compared to the original SPI system, which we have here demonstrated with two linear bacteriocin peptides: leucocin A and lactococcin A. The yields obtained for both peptides after purification were also improved compared to the previous SPI system as a result of this streamlined protocol. CONCLUSIONS This modified SPI system and its simplified cloning and purification procedures described here may be generally useful as a heterologous E. coli expression system to obtain pure peptides in high yield, especially when degradation of the target peptide is an issue.

Protein Expr Purif 2022; 198:106128.

Abstract
Cre recombinase is a widely-used genetic manipulation of genomic DNA. However, the conventional transfection of the DNA vectors expressing the Cre recombinase or viral transduction method yields low transfection efficiencies or insertion mutagenesis. The present paper evaluated whether the direct protein delivery of Cre recombinase through electroporation can induce the Cre-mediated recombination in the HEK 293T cells. Here, the small ubiquitin-related modifier (SUMO) -tagged His-Cre fusion protein was expressed in a soluble pattern in the Eschrichria coli (E.coli) cells, purified using affinity chromatography, and finally electroporated into the HEK 293T cells. These cells were previously transfected with three different Cre reporter vectors. The electroporation of the HEK 293T cells revealed either the activation of EGFP expression, or a decrease in RFP expression, and a concomitant increase in EGFP expression, indicating a desired recombinase-mediated cassette exchange (RMCE) event (conversion of RFP to EGFP), and a biological activity of the purified SUMO-His-Cre protein, which is expected to serve in the Easi-CRISPR-LoxP-mediated genome editing to generate transgenic animal models.

Avsar B. Effective Strategies for Heterologous Expression of Plant Heterotrimeric
G-protein γ Subunits without Gβ Subunit Partners. Protein Pept Lett 2022; 29:429-439. [DOI: 10.2174/0929866529666220203094448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 11/27/2021] [Accepted: 12/13/2021] [Indexed: 11/22/2022]
Abstract
Background:
In plants, heterotrimeric G-protein (Gγ) subunits are diverse, and they have
structural plasticity to provide functional selectivity to the heterotrimer. Although the Gβ and Gγ
subunits dimerize to function in the signaling pathway, the interaction mechanism of various Gγ
subunits with the Gβ subunit partners is still elusive.
Objective:
To better understand the interaction mechanism, one approach is to separate the subunits
for the re-assembly in vitro. Hence, developing a reliable method for achieving the efficient
production and purification of these proteins has become necessary.
Method:
In this study, Gγ1 and Gγ2 proteins from Oryza sativa and Arabidopsis thaliana were
successfully identified, cloned, expressed in bacteria, and purified as recombinant proteins with the
fusion tags. Highly expressed recombinant Gγ subunits in E. coli were digested by proteases, which
were also produced in the presented study.
Results:
Preliminary structural characterization studies without the Gβ partners showed that Gγ1
proteins have disordered structures with coiled-coil, α-helix extensions, and loops, whereas the Gγ2
protein has a more dominant β-sheet and turns structure. Finally, computational analyses performed
on Gγ genes have laid the foundation of new targets for biotechnological purposes.
Conclusion:
The proposed optimized expression and purification protocol can contribute to
investigations on the Gβγ binding mechanism in plant G-protein signaling. The investigations on
selective binding are critical to shed light on the role(s) of different plant Gγ subunit types in
biological processes.

Abstract
Interleukin-24 (IL-24) can specifically induce apoptosis in a broad range of cancer cells without harming normal cells. The interaction of contortrostatin (CN) with integrins on angiogenic vascular endothelial and tumor cells is modulated by the RGD motifs that can significantly inhibit metastasis and angiogenesis. To achieve superior therapeutic efficacy by combining anti-metastasis with tumor-selective apoptosis activity, CN was fused at the C-terminus of IL-24 with a flexible linker (G4S)2, and the recombinant IL-24-CN was expressed in Escherichia coli as a Thioredoxin (Trx)/IL-24-CN fusion protein. The target protein was purified using nickel affinity chromatography. Furthermore, we simplified the purification process by purifying Trx-IL-24-CN and cleaving the Trx tag in one step. The final yield of IL-24-CN was 27.6 mg/L based on flask fermentation. In vitro activity assay demonstrated that the recombinant IL-24-CN could more effectively suppress tumor growth and induce apoptosis of melanoma cells. Scratch and transwell assays suggested that IL-24-CN strongly reduced the migration and invasion behavior of melanoma cells. Immunofluorescence analysis and cell adhesion assay showed that CN could evidently improve the tumor inhibition capability of IL-24 by enhancing the affinity of recombinant protein toward cancer cells. In summary, a highly efficient strategy was developed for producing the bioactive IL-24-CN from prokaryotic cells, supporting IL-24-CN in melanoma therapy.Key points• Efficient heterologous production of recombinant IL-24-CN in E. coli using Trx fusion strategy.• Improved tumor growth suppression and apoptosis induction potency of IL-24-CN.• Enhanced cell adhesion ability of IL-24-CN in cancer cells.

SUMO-fusion and autoinduction-based combinatorial approach for enhanced production of bioactive human interleukin-24 in Escherichia coli. Appl Microbiol Biotechnol 2020; 104:9671-9682.

Abstract
High-level production of recombinant human interleukin-24 (IL-24), a multifunctional immunomodulatory cytokine, has been challenging due primarily to its aggregation as inclusion bodies in the bacterial host while persistent poor-expression in the insect/mammalian expression systems. The present study presents a robust, vector-host combination (pE-SUMO-IL24), auto-inducible medium (YNG/M9NG), and a simple purification scheme for soluble, bioactive, and cost-effective production of native-like IL-24 (nIL-24) in Escherichia coli. The final protein yield, following a three-step purification scheme (IMAC, SEC, dialysis), was 98 mg/L in shake-flask culture (with scale-up potential), which was several folds higher than reported earlier. In vitro cytotoxicity assays with HeLa and HCT116 cancer cell lines (performed using different concentrations of nIL-24) and the fluorescence activated cell sorting analysis (FACS) revealed a dose- and concentration-dependent increase in the population of pro-apoptotic cells with concomitant, statistically significant drop in the number of cells existent at Go/G1-, S-, and G2/M-phases (P < 0.002). The bioactive nIL-24, developed through this study, holds promise for use in further functional characterizations/applications. KEY POINTS: • Yeast SUMO fusion partner at N-terminus for improved solubility of an otherwise insoluble IL-24 in E. coli. • Enhanced cell densities with concomitant several-fold increase in protein yield by lactose-inducible media. • Improved inhibition of cervical and colorectal carcinomas by native-like nIL-24 compared with Met-containing IL. • Heterologous nIL-24 may enable better understanding of the functional intricacies linked up with its unique cancer-specific features.

Abstract
Immunotoxins are a class of recombinant proteins which consist of an antibody and a part of a bacterial or herbal toxin. Immunotoxins containing Pseudomonas aeruginosa exotoxin A (PEA) have been found to be very applicable in clinical trials. Many obstacles such as solubility and absorbency reduce their usability in solid tumors. The current study aims to overcome the mentioned barriers by addition and removal of functional and non-functional domains with a structural approach. In the experimental section, we took advantage of molecular dynamics simulations to predict the functionality of candidate immunotoxins which target human HER2 receptors and confirmed our findings with in vitro experiments. We found out when no changes were made to domain II of PEA, addition of solubilizing domains to immunotoxins would not reduce their targeting and anti-tumor activity, while increasing the yield of expression and stability. On the other side, when we replaced domain II with eleven amino acids of furin cleavage site (FCS), the activity of the immunotoxin was mainly affected by the FCS neighboring domains and linkers. A combination of seven beneficial point mutations in domain III was also assessed and reconfirmed that the toxicity of the immunotoxin would be reduced dramatically. The obtained results indicate that the addition or removal of domains cannot depict the activity of immunotoxins and the matter should be assessed structurally in advance.

Abstract
Kumamolisin from Alicyclobacillus sendaiensis strain NTAP-1 is a serine protease with collagenase activity. After molecular engineering, a kumamolisin mutant, named Kuma030, was obtained with high proteolytic activity against gluten, which might cause celiac disease. Kuma030 exhibited its potential application in industrial and medicine, while challenges remained of its large-scale purification and production. In the studies here, we successfully overexpressed the Kuma030 in E. coli BL21 (DE3) by anchoring a SUMO (Small Ubiquitin-like Modifier) fusion protein at its N-terminal end. In addition, a fast protein purification procedure was developed according to the acidophilic and thermophilic properties of Alicyclobacillus sendaiensis. After a simple acid treatment followed by a heat treatment, a total of 9.9 mg functional Kuma030 was quickly obtained form 1 L LB media culture. This purified Kuma030 was confirmed to be functional to cleave the PQ sequences in a designed protein substrate, and the gluten in actual food samples, such as whole wheat bread and beer, in a fast manner. Our studies provided an efficient strategy for the overexpression and purification of functional Kuma030 in E. coli, which might expand its broad practical applications.

Construction and characterization of the recombinant immunotoxin RTA-4D5-KDEL targeting HER2/neu-positive cancer cells and locating the endoplasmic reticulum. Appl Microbiol Biotechnol 2018; 102:9585-9594. [PMID: 30141083 DOI: 10.1007/s00253-018-9291-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Revised: 07/28/2018] [Accepted: 08/01/2018] [Indexed: 10/28/2022]
Abstract
The specific targeting of immunotoxins enables their wide application in cancer therapy. The A-chain of the ricin protein (RTA) is an N-glycosidase that catalyzes the removal of adenine from the 28S rRNA, preventing protein translation and leading to cell death. Ricin is highly toxic but can only exert its toxic effects from within the cytoplasm. In this study, we linked the anti-HER2 single-chain variable fragment 4D5 scFv and the endoplasmic reticulum-targeting peptide KDEL to the C-terminal of the RTA to construct immunotoxin RTA-4D5-KDEL. In vitro experiments showed that the anticancer effect of RTA-4D5-KDEL towards ovarian cancer cells SKOV-3 increased 440-fold and 28-fold relative to RTA and RTA-4D5, respectively. RTA-4D5-KDEL had a strong inhibitory effect on HER2-overexpressing SKOV-3 cells and caused little damage to normal HEK-293 cells and H460 lung cancer cells. Immunofluorescence experiments showed that the immunotoxin RTA-4D5 could specifically bind to SKOV-3 cells, but not to normal cells HEK-293. The immunotoxin RTA-4D5-KDEL could rapidly localize the recombinant protein to the endoplasmic reticulum. These results suggest that the recombinant immunotoxin RTA-4D5-KDEL has a strong inhibitory effect on ovarian cancer cells that overexpress HER2 but little harm to the normal cells.

Abstract
In the work a recombinant chemotaxis protein CheW from Thermotoga petrophila RKU-1 (TpeCheW) and its mutant homolog (TpeCheW-mut) were created. It was shown that, despite the low homology with CheW prototypes from intestinal bacteria, these proteins didn't cause metabolic overload and were well expressed by cells of E. coli laboratory strains. We have discovered a broad spectrum of industrial valuable properties of the TpeCheW-mut protein such as stability in a wide range of temperatures and pH, high expression level, solubility and possibility of the application of a simple low-stage purification methodology with the use of preliminary heat treatment. Possible directions of the scientific and industrial application of this protein were claimed.

Functional expression and purification of recombinant Hepcidin25 production in Escherichia coli using SUMO fusion technology. Gene 2017; 610:112-117.

Abstract
Hepcidin25 is a small cysteine-rich peptide hormone known as a new class of antimicrobial peptides. The purpose of the present study was to express, purify and investigate the antibacterial properties of recombinant human hepcidin25 protein production in Escherichia coli. Human hepcidin25 gene was optimized and fused to a small ubiquitin-related modifier (SUMO) gene for higher expression. Then SUMO-hepcidin25 was cloned into the pET-32a (+) vector and expressed in E. coli Origami. The fusion protein with a molecular weight of approximately 35kDa was analyzed on SDS-PAGE gel. The highest expression was observed after 6h induction and the fusion protein consisted approximately 47% of the total cellular protein. The purified SUMO-hepcidin25 purity was determined to be higher than 95%, with a final yield of 3.9mgl-1 of media. The recombinant hepcidin25 showed antibacterial activity against both Gram negative (Klebsiella pneumonia) and Gram positive (Staphylococcus aureus and Bacillus cereus) bacteria with minimum inhibitory concentrations (MICs) of 150μgml-1, 18.7μg/ml-1 and 37.5μg/ml-1, respectively. These results indicated that thioredoxin and SUMO dual fusion system is an efficient production system for synthesis functional human hepcidin25.

Abstract
Virtually all recombinant proteins are now prepared using fusion domains also known as "tags". The use of tags helps to solve some serious problems: to simplify procedures of protein isolation, to increase expression and solubility of the desired protein, to simplify protein refolding and increase its efficiency, and to prevent proteolysis. In this review, advantages and disadvantages of such fusion tags are analyzed and data on both well-known and new tags are generalized. The authors own data are also presented.

Abstract
Ubiquitin-like protease 1 (Ulp1) of Saccharomyces cerevisiae emerges as a fundamental tool to obtain the natural N-terminal target protein by cleavage of the small ubiquitin-related modifier (SUMO) fusion protein. However, the costly commercial Ulp1 and its complicated procedures limit its application in the preparation of the target protein with natural N-terminal sequence. Here, we describe the preparation of bioactive codon-optimized recombinant truncated Ulp1 (Leu403-Lys621) (rtUlp1) of S. cerevisiae in Escherichia coli using only one-step with Ni–NTA affinity chromatograph, and the application of rtUlp1 to cleave the SUMO fusion protein by simply mixing the purified rtUlp1, SUMO fusion protein and DL-Dithiothreitol in Tris–HCl buffer. The optimal expression level of non-fusion protein rtUlp1 accounts for approximately 50 % of the total cellular protein and 36 % of the soluble form by addition of isopropyl β-D-l-thiogalactopyranoside at a final concentration of 0.4 mM at 18 °C for 20 h. The purification of target protein rtUlp1 was conducted by Ni–NTA affinity chromatography. The final yield of rtUlp1 was 45 mg/l in flask fermentation with a purity up to 95 %. Furthermore, the high purity of rtUlp1 could effectively cleave the SUMO-tTβRII fusion protein (SUMO gene fused to truncated transforming growth factor-beta receptor type II gene) with the above simplified approach, and the specific activity of the rtUlp1 reached up to 2.8 × 104 U/mg, which is comparable to the commercial Ulp1. The preparation and application strategy of the rtUlp1 with commonly available laboratory resources in this study will be convenient to the cleavage of the SUMO fusion protein to obtain the natural N-terminal target protein, which can be implemented in difficult-to-express protein functional analysis.
