[PMID: 36838891 PMCID: PMC9965216 DOI: 10.3390/molecules28041901] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 02/12/2023] [Accepted: 02/14/2023] [Indexed: 02/19/2023] Open
Abstract
The incorporation of photoproteins into proteins of interest allows the study of either their localization or intermolecular interactions in the cell. Here we demonstrate the possibility of in vivo incorporating the photoprotein Aequorea victoria enhanced green fluorescent protein (EGFP) or Gaussia princeps luciferase (GLuc) into the tetradecameric quaternary structure of GroEL chaperonin and describe some physicochemical properties of the labeled chaperonin. Using size-exclusion and affinity chromatography, electrophoresis, fluorescent and electron transmission microscopy (ETM), small-angle X-ray scattering (SAXS), and bioluminescence resonance energy transfer (BRET), we show the following: (i) The GroEL14-EGFP is evenly distributed within normally divided E. coli cells, while gigantic undivided cells are characterized by the uneven distribution of the labeled GroEL14 which is mainly localized close to the cellular periplasm; (ii) EGFP and likely GLuc are located within the inner cavity of one of the two GroEL chaperonin rings and do not essentially influence the protein oligomeric structure; (iii) GroEL14 containing either EGFP or GLuc is capable of interacting with non-native proteins and the cochaperonin GroES.

Abstract
Chaperones play a vital role in the life of cells by facilitating the correct folding of other proteins and maintaining them in a functional state, being themselves, as a rule, more stable than the rest of cell proteins. Their functional properties naturally tempt investigators to actively adapt them for biotechnology needs. This review will mostly focus on the applications found for the bacterial chaperonin GroE and its counterparts from other organisms, in biotechnology or for research purposes, both in their engineered or intact versions.

Abstract
Hydrophobic recombinant proteins often tend to aggregate upon expression into inclusion bodies and are difficult to refold. Producing them in soluble forms constitutes a common bottleneck problem. A fusion system for production of insoluble hydrophobic proteins in soluble stable forms with thermophilic minichaperone, GroEL apical domain (GrAD) as a carrier, has recently been developed. To provide the utmost flexibility of the system for interactions between the carrier and various target protein moieties a strategy of making permutated protein variants by gene engineering has been applied: the original N- and C-termini of the minichaperone were linked together by a polypeptide linker and new N- and C-termini were made at desired parts of the protein surface. Two permutated GrAD forms were created and analyzed. Constructs of GrAD and both of its permutated forms fused with the initially insoluble N-terminal fragment of hepatitis C virus' E2 protein were tested. Expressed fusions formed inclusion bodies. After denaturation, all fusions were completely renatured in stable soluble forms. A variety of permutated GrAD variants can be created. The versatile format of the system provides opportunities for choosing an optimal pair between particular target protein moiety and the best-suited original or specific permutated carrier.

Abstract
Membrane proteins such as cytokine receptors and G protein-coupled receptors can be drug targets. Recently, we have generated specific monoclonal antibodies (mAbs) against the mouse IL-9 receptor (IL-9R) and found that IL-9R on memory B cells have critical roles in T-dependent immune response. So far, most antibodies against cell surface proteins have been generated by immunization of animals with recombinant proteins produced in Escherichia coli (E. coli) or peptides derived from the protein. However, such antibodies often fail to recognize native proteins on cell surfaces because these antigens lack posttranslational modification and natural protein conformations. To circumvent such problems, we have developed a mouse immunization method, the DNA-immunization utilizing hyaluronidase and E. coli GroEL. Herein, we report an application of the original mouse immunization method in rats to generate anti-mouse IL-9R mAbs which could react with the native form of mouse IL-9R on cell surfaces. Thus, we suggest that the DNA-immunization method is feasible for generating monoclonal antibodies against cell surface proteins in rats.

Abstract
We have developed a fusion system for reliable production of insoluble hydrophobic proteins in soluble stable forms. A carrier is thermophilic minichaperone, GroEL apical domain (GrAD), a 15 kDa monomer able to bind diverse protein substrates. The Met-less variant of GrAD has been made for further convenient use of Met-specific CNBr chemical cleavage, if desired. The Met-less GrAD retained stability and solubility of the original protein. Target polypeptides can be fused to either C-terminus or N-terminus of GrAD. The system has been tested with two unrelated insoluble proteins fused to the C-terminus of GrAD. One of the proteins was also fused to GrAD N-terminus. The fusions formed inclusion bodies at 25°C and above and were partly soluble only at lower expression temperatures. Most importantly, however, after denaturation in urea, all fusions without exception were completely renatured in soluble stable forms that safely survived freezing-thawing as well as lyophilization. All fusions for both tested target proteins retained solubility at high concentrations for days. Functional analysis revealed that a target protein may retain functionality in the fusion. Convenience features include potential thermostability of GrAD fusions, capacity for chemical and enzymatic cleavage of a target and His6 tag for purification.

Abstract
Antibody-based drug research involves the preparation of polyclonal and monoclonal antibodies, especially those that are reactive with native G protein-coupled receptors (GPCRs) on the cell membrane. Here, we report that DNA immunization of mice with a plasmid that encodes endothelin A receptor (ETAR) fused to Escherichia coli (E. coli) GroEL at its C-terminus (ETAR-GroEL) induced very strong and specific antibody responses to native ETAR. Co-injection of plasmids that expressed ETAR and GroEL (ETAR+GroEL) induced significantly lower antibody responses compared with the ETAR-GroEL plasmid. Monoclonal antibodies that are prepared by using GroEL as a molecular adjuvant could be used in immunoassays, such as flow cytometry, western blotting, and immunoprecipitation, to detect both exogenous and endogenous ETAR. The adjuvant activity of GroEL might involve inflammatory cytokine mediators via Toll-like receptor 4 in addition to the anticipated carrier effect. DNA immunization using GroEL might become a standard method for producing antibodies that are useful for the functional analysis of GPCRs.

Abstract
The hyperthermophilic archaeon Thermococcus sp. strain KS-1 (T. KS-1) expresses two different chaperonin subunits, alpha and beta, for the folding of its proteins. The composition of the subunits in the hexadecameric double ring changes with temperature. The content of the beta subunit significantly increases according to the increase in temperature. The homo-oligomer of the beta subunit, Cpn beta, is more thermostable than that of the alpha subunit, Cpn alpha. Since Cpn alpha and Cpn beta also have different protein folding activities and interactions with prefoldin, the hetero-oligomer is thought to exhibit different characteristics according to the content of subunits. The hetero-oligomer of the T. KS-1 chaperonin has not been studied, however, because the alpha and beta subunits form hetero-oligomers of varying compositions when they are expressed simultaneously. In this study, we characterized the T. KS-1 chaperonin hetero-oligomer, Cpn alphabeta, containing both alpha and beta in the alternate order, which was constructed by the expression of alpha and beta subunits in a coordinated fashion and protease digestion. Cpn alphabeta protected citrate synthase from thermal aggregation, promoted the folding of acid-denatured GFP in an ATP-dependent manner, and exhibited an ATP-dependent conformational change. The yield of refolded GFP generated by Cpn alphabeta was almost equivalent to that generated by Cpn beta but lower than that generated by Cpn alpha. In contrast, Cpn alphabeta exhibited almost the same level of thermal stability as Cpn alpha, which was lower than that of Cpn beta. The affinity of Cpn alphabeta to prefoldin was found to be between those of Cpn alpha and Cpn beta, as expected.

Abstract
ATP drives the conformational change of the group II chaperonin from the open lid substrate-binding conformation to the closed lid conformation to encapsulate an unfolded protein in the central cavity. The detailed mechanism of this conformational change remains unknown. To elucidate the intra-ring cooperative action of subunits for the conformational change, we constructed Thermococcus chaperonin complexes containing mutant subunits in an ordered manner and examined their folding and conformational change abilities. Chaperonin complexes containing wild-type subunits and mutant subunits with impaired ATP-dependent conformational change ability or ATP hydrolysis activity, one by one, exhibited high protein refolding ability. The effects of the mutant subunits correlate with the number and order in the ring. In contrast, the use of a mutant lacking helical protrusion severely affected the function. Interestingly, these mutant chaperonin complexes also exhibited ATP-dependent conformational changes as demonstrated by small angle x-ray scattering, protease digestion, and changes in fluorescence of the fluorophore attached to the tip of the helical protrusion. However, their conformational change is likely to be transient. They captured denatured proteins even in the presence of ATP, whereas addition of ATP impaired the ability of the wild-type chaperonin to protect citrate synthase from thermal aggregation. These results suggest that ATP binding/hydrolysis causes the independent conformational change of the subunit, and further conformational change for the complete closure of the lid is induced and stabilized by the interaction between helical protrusions.

Abstract
PURPOSE This study compared gene expression profiles in mouse lungs after administration of the cationic polymers polyethyleneimine (PEI) or chitosan alone or formulated with a luciferase reporter plasmid (PEI-pLuc, chitosan-pLuc). METHODS The polymers and formulations were administered intratracheally to Balb/c mice at doses judged to be nontoxic according to intracellular dehydrogenase activity and tissue morphology. RNA was isolated from the lungs 24 or 72 h after administration, and a dedicated stress and toxicology cDNA array was used to monitor the in vivo response to the gene delivery system in the lung tissue. RESULTS The gene expression profiles differed between the PEI and chitosan groups with regard to both the total number and the type of expressed genes. Chitosan-pLuc upregulated genes that protect the cell from oxidative stress and inflammation, such as heme oxygenase-1 and catalase, whereas PEI-pLuc upregulated genes involved in inflammatory processes, such as the cyclooxygenases 1 and 2, indicating possible involvement in the development of adverse reactions. However, both polymers activated genes involved in reaction to stress, such as DNA damage repair. Furthermore, in the PEI group, chaperone genes and members of the p38 mitogen-activated protein kinase pathway were also upregulated, suggesting a possible explanation for the better performance of PEI in gene delivery systems. CONCLUSIONS The results indicate that gene expression profiling is a useful and sensitive tool for the evaluation of tissue responses after administration of polymers or gene delivery systems. The results also suggest a possible explanation for the differences in gene delivery performance between the two polymers in gene delivery systems.
