Abstract
Therapeutic proteins garnered significant attention in the field of disease treatment. In comparison to small molecule drugs, protein therapies offer distinct advantages, including high potency, specificity, low toxicity, and reduced carcinogenicity, even at minimal concentrations. However, the full potential of protein therapy is limited by inherent challenges such as large molecular size, delicate tertiary structure, and poor membrane penetration, resulting in inefficient intracellular delivery into target cells. To address these challenges and enhance the clinical applications of protein therapies, various protein-loaded nanocarriers with tailored modifications were developed, including liposomes, exosomes, polymeric nanoparticles, and nanomotors. Despite these advancements, many of these strategies encounter significant issues such as entrapment within endosomes, leading to low therapeutic efficiency. In this review, we extensively discussed diverse strategies for the rational design of nanocarriers, aiming to overcome these limitations. Additionally, we presented a forward-looking viewpoint on the innovative generation of delivery systems specifically tailored for protein-based therapies. Our intention was to offer theoretical and technical support for the development and enhancement of nanocarriers capable of facilitating cytosolic protein delivery.

Abstract
Nudix hydrolase 9 (NUDT9) is a member of the nucleoside linked to another moiety X (NUDIX) protein superfamily, which hydrolyses a broad spectrum of organic pyrophosphates from metabolic processes. ADP‐ribose (ADPR) has been the only known endogenous substrate accepted by NUDT9 so far. The Ca2+‐permeable transient receptor potential melastatin subfamily 2 (TRPM2) channel contains a homologous NUDT9‐homology (NUDT9H) domain and is activated by ADPR. Sustained Ca2+ influx via ADPR‐activated TRPM2 triggers apoptotic mechanisms. Thus, a precise regulation of cellular ADPR levels by NUDT9 is essential. A detailed characterization of the enzyme‐substrate interaction would help to understand the high substrate specificity of NUDT9. Here, we analysed ligand binding to NUDT9 using a variety of biophysical techniques. We identified 2′‐deoxy‐ADPR as an additional substrate for NUDT9. Similar enzyme kinetics and binding affinities were determined for the two ligands. The high‐affinity binding was preserved in NUDT9 containing the mutated NUDIX box derived from the human NUDT9H domain. NMR spectroscopy indicated that ADPR and 2′‐deoxy‐ADPR bind to the same binding site of NUDT9. Backbone resonance assignment and subsequent molecular docking allowed further characterization of the binding pocket. Substantial conformational changes of NUDT9 upon ligand binding were observed which might allow for the development of NUDT9‐based ADPR fluorescence resonance energy transfer sensors that may help with the analysis of ADPR signalling processes in cells in the future.

Delivery of Mixed-Lineage Kinase Domain-Like Protein by Vapor Nanobubble Photoporation Induces Necroptotic-Like Cell Death in Tumor Cells. Int J Mol Sci 2019; 20:ijms20174254. [PMID: 31480289 PMCID: PMC6747363 DOI: 10.3390/ijms20174254] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 08/23/2019] [Accepted: 08/29/2019] [Indexed: 02/02/2023] Open
Abstract
Modern molecular medicine demands techniques to efficiently deliver molecules directly into mammalian cells. As proteins are the final mediators of most cellular pathways, efficient intracellular protein delivery techniques are highly desired. In this respect, photoporation is a promising recent technique for the delivery of proteins directly into living cells. Here, we show the possibility to deliver a model saccharide (FD70) and a model protein (FITC-BSA) into murine B16 melanoma cells by using the vapor nanobubble photoporation technique with an efficiency of 62% and 38%, respectively. Next, we delivered the mixed-lineage kinase domain-like (MLKL) protein, the most terminal mediator of necroptosis currently known, and caspase-8 and -3 protein, which are important proteins in the initiation and execution of apoptosis. A significant drop in cell viability with 62%, 71% and 64% cell survival for MLKL, caspase-8 and caspase-3, respectively, was observed. Remarkably, maximal cell death induction was already observed within 1 h after protein delivery. Transduction of purified recombinant MLKL by photoporation resulted in rapid cell death characterized by cell swelling and cell membrane rupture, both hallmarks of necroptosis. As necroptosis has been identified as a type of cell death with immunogenic properties, this is of interest to anti-cancer immunotherapy. On the other hand, transduction of purified recombinant active caspase-3 or -8 into the tumor cells resulted in rapid cell death preceded by membrane blebbing, which is typical for apoptosis. Our results suggest that the type of cell death of tumor cells can be controlled by direct transduction of effector proteins that are involved in the executioner phase of apoptosis or necroptosis.

Abstract
Nanoparticle laser interactions are in widespread use in cell manipulation. In particular, molecular medicine needs techniques for the directed delivery of molecules into mammalian cells. Proteins are the final mediator of most cellular cascades. However, despite several methodical approaches, the efficient delivery of proteins to cells remains challenging. This paper presents a new protein transfection technique via laser scanning of cells previously incubated with gold nanoparticles. The laser-induced plasmonic effects on the gold nanoparticles cause a transient permeabilization of the cellular membrane, allowing proteins to enter the cell. Applying this technique, it was possible to deliver green fluorescent protein into mammalian cells with an efficiency of 43%, maintaining a high level of cell viability. Furthermore, a functional delivery of Caspase 3, an apoptosis mediating protein, was demonstrated and evaluated in several cellular assays. Compared to conventional protein transfection techniques such as microinjection, the methodical approach presented here enables high-throughput transfection of about 10 000 cells per second. Moreover, a well-defined point in time of delivery is guaranteed by gold nanoparticle mediated laser transfection, allowing the detailed temporal analysis of cellular pathways and protein trafficking.

Abstract
The global impairment of mature microRNAs (miRNAs) is emerging as a common feature of human tumors. One interesting scenario is that defects in the nuclear export of precursor miRNAs (pre-miRNAs) might occur in transformed cells. Exportin 5 (XPO5) mediates pre-miRNA nuclear export and herein we demonstrate the presence of XPO5-inactivating mutations in a subset of human tumors with microsatellite instability. The XPO5 genetic defect traps pre-miRNAs in the nucleus, reduces miRNA processing, and diminishes miRNA-target inhibition. The XPO5 mutant form lacks a C-terminal region that contributes to the formation of the pre-miRNA/XPO5/Ran-GTP ternary complex and pre-miRNAs accumulate in the nucleus. Most importantly, the restoration of XPO5 functions reverses the impaired export of pre-miRNAs and has tumor-suppressor features.
