Abstract
In sensory neurons that transmit pain signals, whether acute or chronic, voltage-gated sodium channels (VGSCs) are crucial for regulating excitability. NaV1.1, NaV1.3, NaV1.6, NaV1.7, NaV1.8, and NaV1.9 have been demonstrated and defined their functional roles in pain signaling based on their biophysical properties and distinct patterns of expression in each subtype of sensory neurons. Scorpions and spiders are traditional Chinese medicinal materials, belonging to the arachnid class. Most of the studied species of them have evolved venom peptides that exhibit a wide variety of knottins specifically targeting VGSCs with subtype selectivity and conformational specificity. This review provides an overview on the exquisite knottins from scorpion and spider venoms targeting pain-related NaV channels, describing the sequences and the structural features as well as molecular determinants that influence their selectivity on special subtype and at particular conformation, with an aim for the development of novel research tools on NaV channels and analgesics with minimal adverse effects.

Application of an Autoinduction Strategy to Optimize the Heterologous Production of an Antitumor Bispecific Fusion Protein Based on the TRAIL Receptor-Selective Mutant Variant in Escherichia coli. Mol Biotechnol 2023; 65:581-589. [PMID: 36094644 DOI: 10.1007/s12033-022-00561-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Accepted: 09/06/2022] [Indexed: 10/14/2022]
Abstract
Autoinduction is a simple approach for heterologous protein expression that helps to achieve the high-level production of recombinant proteins in soluble form. In this work, we investigated if the application of an autoinduction strategy could help to optimize the production of bifunctional protein SRH-DR5-B, the DR5-specific TRAIL variant DR5-B fused to a VEGFR2-specific peptide SRHTKQRHTALH for dual antitumor and antiangiogenic activity. The protein was expressed in Escherichia coli SHuffle B T7, BL21(DE3), and BL21(DE3)pLysS strains. By IPTG induction, the highest expression level was in SHuffle B T7, while by autoinduction, the similar expression level was achieved in BL21(DE3)pLysS. However, in SHuffle B T7, only 45% of IPTG-induced SRH-DR5-B was expressed in soluble form, in contrast to 75% autoinduced in BL21(DE3)pLysS. The yield of purified SRH-DR5-B protein expressed by autoinduction in BL21(DE3)pLysS was 28 ± 4.5 mg per 200 ml of cell culture, which was 1.4 times higher than the yield from IPTG-induced SHuffle B T7. Regardless of the production method, SRH-DR5-B was equally cytotoxic to BxPC-3 human tumor cells expressing DR5 and VEGFR2 receptors. Thus, the production of SRH-DR5-B by autoinduction in the E. coli BL21(DE3)pLysS strain is an efficient, technologically simple, and economical technique that allows to obtain a large amount of active protein from the cytoplasmic cell fraction. Our work demonstrates that the strategy of induction of protein expression is no less important than the strain selection.

Strategies for Heterologous Expression, Synthesis, and Purification of Animal Venom Toxins. Front Bioeng Biotechnol 2022; 9:811905. [PMID: 35127675 PMCID: PMC8811309 DOI: 10.3389/fbioe.2021.811905] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 12/24/2021] [Indexed: 11/13/2022] Open
Abstract
Animal venoms are complex mixtures containing peptides and proteins known as toxins, which are responsible for the deleterious effect of envenomations. Across the animal Kingdom, toxin diversity is enormous, and the ability to understand the biochemical mechanisms governing toxicity is not only relevant for the development of better envenomation therapies, but also for exploiting toxin bioactivities for therapeutic or biotechnological purposes. Most of toxinology research has relied on obtaining the toxins from crude venoms; however, some toxins are difficult to obtain because the venomous animal is endangered, does not thrive in captivity, produces only a small amount of venom, is difficult to milk, or only produces low amounts of the toxin of interest. Heterologous expression of toxins enables the production of sufficient amounts to unlock the biotechnological potential of these bioactive proteins. Moreover, heterologous expression ensures homogeneity, avoids cross-contamination with other venom components, and circumvents the use of crude venom. Heterologous expression is also not only restricted to natural toxins, but allows for the design of toxins with special properties or can take advantage of the increasing amount of transcriptomics and genomics data, enabling the expression of dormant toxin genes. The main challenge when producing toxins is obtaining properly folded proteins with a correct disulfide pattern that ensures the activity of the toxin of interest. This review presents the strategies that can be used to express toxins in bacteria, yeast, insect cells, or mammalian cells, as well as synthetic approaches that do not involve cells, such as cell-free biosynthesis and peptide synthesis. This is accompanied by an overview of the main advantages and drawbacks of these different systems for producing toxins, as well as a discussion of the biosafety considerations that need to be made when working with highly bioactive proteins.
