Abstract
The increased risk of breast cancer metastasis is closely linked to the effects of platelets. Our previously light-switchable diphtheria toxin A fragment (DTA) gene system, known as the LightOn system, has demonstrated significant therapeutic potential; it lacks antimetastatic capabilities. In this study, we devised an innovative system by combining cell membrane fusion liposomes (CML) loaded with the light-switchable transgene DTA (pDTA) and a ticagrelor (Tig) prodrug. This innovative system, named the sequential rocket-mode bioactivating drug delivery system (pDTA-Tig@CML), aims to achieve targeted pDTA delivery while concurrently inhibiting platelet activity through the sequential release of Tig triggered by reactive oxygen species with the tumor microenvironment. In vitro investigations have indicated that pDTA-Tig@CML, with its ability to sequentially release Tig and pDTA, effectively suppresses platelet activity, resulting in improved therapeutic outcomes and the mitigation of platelet driven metastasis in breast cancer. Furthermore, pDTA-Tig@CML exhibits enhanced tumor aggregation and successfully restrains tumor growth and metastasis. It also reduces the levels of ADP, ATP, TGF-β, and P-selectin both in vitro and in vivo, underscoring the advantages of combining the bioactivating Tig prodrug nanoplatform with the LightOn system. Consequently, pDTA-Tig@CML emerges as a promising light-switchable DTA transgene system, offering a novel bioactivating prodrug platform for breast cancer treatment.

Abstract
Regulated systems for transgene expression are useful tools in basic research and a promising platform in biomedicine due to their regulated transgene expression by an inducer. The emergence of optogenetics expression systems enabled the construction of light-switchable systems, enhancing the spatial and temporal resolution of a transgene. The LightOn system is an optogenetic tool that regulates the expression of a gene of interest using blue light as an inducer. This system is based on a photosensitive protein (GAVPO), which dimerizes and binds to the UASG sequence in response to blue light, triggering the expression of a downstream transgene. Previously, we adapted the LightOn system to a dual lentiviral vector system for neurons. Here, we continue the optimization and assemble all components of the LightOn system into a single lentiviral plasmid, the OPTO-BLUE system. For functional validation, we used enhanced green fluorescent protein (EGFP) as an expression reporter (OPTO-BLUE-EGFP) and evaluated the efficiency of EGFP expression by transfection and transduction in HEK293-T cells exposed to continuous blue-light illumination. Altogether, these results prove that the optimized OPTO-BLUE system allows the light-controlled expression of a reporter protein according to a specific time and light intensity. Likewise, this system should provide an important molecular tool to modulate gene expression of any protein by blue light.

Spatiotemporally controllable diphtherin transgene system and neoantigen immunotherapy. J Control Release 2023; 355:538-551. [PMID: 36063962 DOI: 10.1016/j.jconrel.2022.08.059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 07/12/2022] [Accepted: 08/29/2022] [Indexed: 02/16/2023]
Abstract
Individualized immunotherapy has attracted great attention due to its high specificity, effectiveness, and safety. We used an exogenous antigen to label tumor cells with MHC I molecules, which allowed neoantigen-specific T cells to recognize and kill tumor cells. A neoantigen vaccine alone cannot achieve complete tumor clearance due to a tumor immunosuppressive microenvironment. The LightOn system was developed to effectively eliminate tumor cells through the spatiotemporally controllable expression of diphtheria toxin A fragment, leading to antigen release in the tumor region. These antigens stimulated and enhanced immunological function and thus, recruited neoantigen-specific T cells to infiltrate tumor tissue. Using the nanoparticle delivery system, neoantigens produced higher delivery efficiency to lymph nodes and improved tumor targeting ability for tumor cell labelling. Good tumor inhibition and prolonged survival were achieved, while eliciting a strong immune response. The combination of a spatiotemporally controllable transgene system with tumor neoantigen labeling has great potential for tumor immunotherapy.

Abstract
Breast cancer is a common malignancy in women. The abnormally dense collagen network in breast cancer forms a therapeutic barrier that hinders the penetration and anti-tumor effect of drugs. To overcome this hurdle, we adopted a therapeutic strategy to treat breast cancer which combined a light-switchable transgene system and losartan. The light-switchable transgene system could regulate expression of the diphtheria toxin A fragment (DTA) gene with a high on/off ratio under blue light and had great potential for spatiotemporally controllable gene expression. We developed a nanoparticle drug delivery system to achieve tumor microenvironment-responsive and targeted delivery of DTA-encoded plasmids (pDTA) to tumor sites via dual targeting to cluster of differentiation-44 and αvβ3 receptors. In vivo studies indicated that the combination of pDTA and losartan reduce the concentration of collagen type I from 5.9 to 1.9 µg/g and decreased the level of active transforming growth factor-β by 75.0% in tumor tissues. Moreover, deeper tumor penetration was achieved, tumor growth was inhibited, and the survival rate was increased. Our combination strategy provides a novel and practical method for clinical treatment of breast cancer.

Abstract
Light-regulated modules offer unprecedented new ways to control cellular behaviour with precise spatial and temporal resolution. Among a variety of bacterial light-switchable gene expression systems, single-component systems consisting of single transcription factors would be more useful due to the advantages of speed, simplicity, and versatility. In the present study, we developed a single-component light-activated bacterial gene expression system (eLightOn) based on a novel LOV domain from Rhodobacter sphaeroides (RsLOV). The eLightOn system showed significant improvements over the existing single-component bacterial light-activated expression systems, with benefits including a high ON/OFF ratio of >500-fold, a high activation level, fast activation kinetics, and/or good adaptability. Additionally, the induction characteristics, including regulatory windows, activation kinetics and light sensitivities, were highly tunable by altering the expression level of LexRO. We demonstrated the usefulness of the eLightOn system in regulating cell division and swimming by controlling the expression of the FtsZ and CheZ genes, respectively, as well as constructing synthetic Boolean logic gates using light and arabinose as the two inputs. Taken together, our data indicate that the eLightOn system is a robust and highly tunable tool for quantitative and spatiotemporal control of bacterial gene expression.

Abstract
Gene therapy with external gene insertion (e. g. a suicide gene) and expression specifically in mutated tumor cells has shown to be a promising strategy in treatment of tumors. However, current tumor gene therapy often suffered from low efficiency in gene expression and off-target effects which may cause damage to normal tissues. To address these issues, in this study, a light-switchable transgene nanoparticle delivery system loaded with a diphtheria toxin A (DTA) segment encoded gene, a suicide gene for tumor cells, was developed. The nanoparticles contained vitamin E succinate-grafted polyethyleneimine core and arginylglycylaspartic acid (RGD)-modified pegylated hyaluronic acid shell for targeted delivery of the loaded gene to tumor cells via receptor-mediated (CD44 and αvβ3) endocytosis. Notably, the expression of target proteins in tumor cells could be conveniently regulated by adjusting the blue light intensity in the Light-On system. In in-vitro studies in cultured B16-F10 cells, the pG-DTA-loaded nano-micelles showed greatly improved inhibitory rate compared with the pG-DTA group. Moreover, in the tumor-bearing C57BL/6 mice model, the pG-DTA-loaded nanoparticle exhibited greatly improved efficacy and reduced systemic toxicity with significantly increased survival rate after 21 days. Significantly suppressed tumor angiogenesis was also identified in the nanoparticle-treated group likely due to the targeting ability of the RGD-modified nanoparticle. All the above results indicated that the combination of a light-switchable transgene system with a nanoparticle-based targeted delivery system have great potentials in gene therapy of malignant tumors with improved precision and efficacy.

Abstract
Breakthroughs in gene synthesis has allowed synthetic biologists the ability to design any DNA sequence of interest, enabling the possibility to create complex systems inside cells with novel functions to tackle problems in immunology. Synthetic immunology of mammalian cells expressing natural or synthetic genes can guide and induce immune responses in patients. Through recent developments in engineering chimeric receptors, it is now feasible to customize control over engineered cells to target the disease sites with specificity. These cells can avoid immune rejection if derived from expandable cell types (e.g., stem cells or T cells) and then can be grown in abundance before implantation. However, safety concerns of engineered cells in circulation necessitates the development of a wide range of mechanisms to kill cells after their therapeutic life ends. This therapeutic effect is still predominantly the secretion of therapeutic proteins, but novel therapeutic interventions have been explored by synthetic biologists. In the pursuit of engineering new cell functions for synthetic immunology, it is possible that many problems previously thought intractable may actually be possible.

Abstract
On-cue regulation of gene transcription is an invaluable tool for the study of biological processes and the development and integration of next-generation therapeutics. Ideal reagents for the precise regulation of gene transcription should be nontoxic to the host system, highly tunable, and provide a high level of spatial and temporal control. Light, when coupled with protein or small molecule-linked photoresponsive elements, presents an attractive means of meeting the demands of an ideal system for regulating gene transcription. In this review, we cover recent developments in the burgeoning field of light-regulated gene transcription, covering both genetically encoded and small-molecule based strategies for optical regulation of transcription during the period 2012 till present.

Abstract
Recent advances in the development of light-inducible transgene expression systems have overcome many inherent drawbacks of conventional chemically regulated systems. The latest generation of those light-regulated systems that are specifically responsive to different wavelengths allows spatiotemporal control of gene expression in a so far unprecedented manner.In this chapter, we first describe the available light-inducible gene expression systems compatible with mammalian cells and explain their underlying mechanisms. Afterward, we give a detailed protocol for the implementation of a UVB light-inducible expression system in mammalian cells.

Abstract
Light-mediated control of protein-protein interactions to regulate metabolic pathways is an important approach of optogenetics. Here, we report the first optogenetic system based on a reversible light-induced binding between a bacterial phytochrome BphP1 and its natural partner PpsR2 from Rhodopseudomonas palustris bacteria. We extensively characterized the BphP1–PpsR2 interaction both in vitro and in mammalian cells, and then used it to translocate target proteins to specific cellular compartments, such as plasma membrane and nucleus. Applying this approach we achieved a light-control of cell morphology resulting in the substantial increase of cell area. We next demonstrated the light-induced gene expression with the 40-fold contrast in cultured cells, 32-fold subcutaneously and 5.7-fold in deep tissues in mice. The unique characteristics of the BphP1–PpsR2 optogenetic system are its sensitivity to 740–780 nm near-infrared light, ability to utilize an endogenous biliverdin chromophore in eukaryotes including mammals, and spectral compatibility with blue-light optogenetic systems.
