Abstract
Background Messenger RNA (mRNA)-based immunogene therapy holds significant promise as an emerging tumor therapy approach. However, the delivery efficiency of existing mRNA methods and their effectiveness in stimulating anti-tumor immune responses require further enhancement. Tumor cell lysates containing tumor-specific antigens and biomarkers can trigger a stronger immune response to tumors. In addition, strategies involving multiple gene therapies offer potential optimization paths for tumor gene treatments. Methods Based on the previously developed ideal mRNA delivery system called DOTAP-mPEG-PCL (DMP), which was formed through the self-assembly of 1.2-dioleoyl-3-trimethylammonium-propane (DOTAP) and methoxypoly (ethylene glycol)-b-poly (ε-caprolactone) (mPEG-PCL), we introduced a fused cell-penetrating peptide (fCPP) into the framework and encapsulated tumor cell lysates to form a novel nanovector, termed CLSV system (CLS: CT26 tumor cell lysate, V: nanovector). This system served a dual purpose of facilitating the delivery of two mRNAs and enhancing tumor immunogene therapy through tumor cell lysates. Results The synthesized CLSV system had an average size of 241.17 nm and a potential of 39.53 mV. The CLSV system could not only encapsulate tumor cell lysates, but also deliver two mRNAs to tumor cells simultaneously, with a transfection efficiency of up to 60%. The CLSV system effectively activated the immune system such as dendritic cells to mature and activate, leading to an anti-tumor immune response. By loading Bim-encoded mRNA and IL-23A-encoded mRNA, CLSV/Bim and CLSV/IL-23A complexes were formed, respectively, to further induce apoptosis and anti-tumor immunity. The prepared CLSV/dual-mRNA complex showed significant anti-cancer effects in multiple CT26 mouse models. Conclusion Our results suggest that the prepared CLSV system is an ideal delivery system for dual-mRNA immunogene therapy.

Abstract
Cationic copolymers are widely used in gene delivery as a non-viral gene vector, but their applications are limited by low transfection efficiency and high cytotoxicity. In order to enhance the transfection efficiency of copolymer micelles to endothelial cells (HUVECs) and reduce their cytotoxicity, this study synthesized an amphipathic multi-targeted copolymer micelle delivery system PCLMD-PPEGMA-NLS-TAT-REDV (TCMs). Gel test results showed that TCMs showed good pZNF580 binding ability and could effectively load the pZNF580 plasmid. The CCK-8 results show that when the concentration of TCMs is greater than 60 μg mL-1, it will affect cell viability and have low cytotoxicity. We found that the multi-targeted copolymer micelles can be effectively taken up by HUVECs in vitro. The transfection efficiency of TCMs@pZNF580 (w/wpZNF580 = 3) to HUVECs was comparable to that of the positive control group lip2000@pZNF580, and WB also showed the same trend. In addition, the TCMs@pZNF580 complex also significantly enhanced the proliferation and migration of HUVECs. The experimental results on blood vessel formation showed that TCMs@pZNF580 accelerated the vascularization of HUVECs. This experiment provided a new technology platform for targeted gene therapy, especially for endothelialization and vascularization. The research results have important reference value for the treatment of cardiovascular diseases.

Abstract
OBJECTIVE The E2F2 transcription factor can accelerate cell proliferation and wound healing. However, its mechanism of action in a diabetic foot ulcer (DFU) remains unclear. Therefore, this study explores the influence of E2F2 on wound healing in DFU by examining cell division cycle-associated 7-like (CDCA7L) expression. METHODS CDCA7L and E2F2 expression in DFU tissues were analyzed with databases. CDCA7L and E2F2 expression were altered in human umbilical vein endothelial cells (HUVECs) and spontaneously transformed human keratinocyte cell culture (HaCaT) cells. Cell viability, migration, colony formation, and angiogenesis were evaluated. Binding of E2F2 to the CDCA7L promoter was examined. Subsequently, a diabetes mellitus (DM) mouse model was established and treated with full-thickness excision followed by CDCA7L overexpression. Wound healing in these mice was observed and recorded, and vascular endothelial growth factor receptor 2 (VEGFR2) and hematopoietic progenitor cell antigen CD34 (CD34) expression were determined. E2F2 and CDCA7L expression levels in cells and mice were evaluated. The expression of growth factors was tested. RESULTS CDCA7L expression was downregulated in DFU tissues and wound tissues from DM mice. Mechanistically, E2F2 bound to the CDCA7L promoter to upregulate CDCA7L expression. E2F2 overexpression enhanced viability, migration, and growth factor expression in HaCaT cells and HUVECs, and augmented HUVEC angiogenesis and HaCaT cell proliferation, which was nullified by silencing CDCA7L. In DM mice, CDCA7L overexpression facilitated wound healing and elevated the expression level of growth factors. CONCLUSIONS E2F2 facilitated cell proliferation and migration and fostered wound healing in DFU cells through binding to the CDCA7L promoter.

H 2O 2-responsive VEGF/NGF gene co-delivery nano-system achieves stable vascularization in ischemic hindlimbs. J Nanobiotechnology 2022; 20:145.

Abstract
Peripheral vascular disease (PVD) is a common clinical manifestation of atherosclerosis. Vascular endothelial growth factor (VEGF) gene therapy is a promising approach for PVD treatment. However, due to single-gene therapy limitations and high H2O2 pathological microenvironment, VEGF gene therapy are not as expectations and its clinical application are limited. Synergistic effects of Nerve factors and vascular factors in angiogenesis have attracted attention in recent years. In this study, VEGF and nerve growth factor (NGF) genes co-delivery nanoparticles (VEGF/NGF-NPs) were prepared by using H2O2 responsive 6s-PLGA-Po-PEG as a carrier. 6s-PLGA-Po-PEG could react with H2O2 specifically due to the internal peroxalate bond. Angiogenic effects of VEGF/NGF-NPs has been evaluated in cells and hindlimb ischemia mice model. Results showed that VEGF/NGF-NPs promoted VEGF and NGF co-expression simultaneously, eliminated excessive H2O2, strengthened reactions between SH-SY5Ys and HUVECs, and finally enhanced migration, tube formation, proliferation and H2O2 damage resistance of HUVECs. VEGF/NGF-NPs also recovered blood perfusion, promoted the expression of VEGF, NGF, eNOS and NO, and enhanced vascular coverage of pericytes. Treatment effects of VEGF/NGF-NPs may related to VEGF/eNOS/NO pathway. Altogether, VEGF/NGF-NPs eliminated excessive H2O2 while achieving gene co-delivery, and promoted stable angiogenesis. It’s a promising way for PVD treatment by using VEGF/NGF-NPs.

Abstract
Burns, trauma, surgery and chronic diabetic ulcers are the most common reasons causing skin wounds in clinic. Thus, developing a functional wound dressing has been an imperative issue. Herein, functional wound dressing (poly(l-lactic acid) PLLA-((tanic acid (TA)/europium (Eu))n ) is fabricated through a facile polyphenol-europium ion assembly to ameliorate wound microenvironment via scavenging excessive reactive oxygen species (ROS) and promoting angiogenesis. The physicochemical characterization indicates that the multicycle assembled TA/Eu is uniformly deposited on PLLA-(TA/Eu)n nanofiber mats surface. In vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH) antioxidant tests display good antioxidant ability by scavenging more than 75% ROS, and significantly increasing the antioxidant enzyme levels in vivo. Cytocompatibility experiments illustrate that PLLA-(TA/Eu)n nanofiber mats can promote the adhesion and proliferation of human umbilical vein endothelial cells (HUVECs) and L929 cells. Meanwhile, real-time quantitative polymerase chain reaction (PCR) (RT-qPCR) and western blot assays illustrate that it can stimulate proangiogenesis by elevating the expression of angiogenesis-related genes and proteins. In vivo Sprague-Dawley (SD) rats experiments indicate that PLLA-(TA/Eu)n nanofiber mats can significantly promote wound healing by improving both angiogenesis and antioxidant activity. Taken together, the functional PLLA-(TA/Eu)n nanofiber mats can offer significant promise as wound dressing for accelerated wound healing.

Abstract
As an urgently needed device for vascular diseases, the small-diameter vascular graft is limited by high thrombogenicity in clinical applications. Rapid endothelialization is a promising approach to construct an antithrombogenic inner surface of the vascular graft. The main bottleneck for rapid endothelialization is the adhesion, migration, and proliferation of endothelial cells (ECs) in situ of the small-diameter vascular graft. Herein, we innovatively fabricated an intelligent gene delivery small-caliber vascular graft based on electrospun poly(lactic acid-co-caprolactone) and gelatin for rapid in situ endothelialization. The graft surface was co-modified with EC adhesive peptide of Arg-Glu-Asp-Val (REDV) and responsive gene delivery system. REDV can selectively adhere ECs onto the graft surface; subsequently, the overexpressed matrix metalloproteinase by ECs can effectively cleave the linker peptide GPQGIWGQ-C; and finally, the gene complexes were intelligently and enzymatically released from the graft surface, and thereby, the gene can efficiently transfect ECs. Importantly, this enzymatically releasing gene surface has been proven to be safe and temporarily stable in blood flow owing to the biotin-avidin interaction to immobilize gene complexes on the inner surface of vascular grafts through the GPQGIWGQ-C peptide linker. It has the advantage of specifically adhering the ECs to the surface and smartly transfecting them with high transfection efficiency. The co-modified surface has been demonstrated to accelerate the luminal endothelialization in vivo, which might be attributed to the synergistic effect of REDV and effective gene transfection. Particularly, the intelligent and responsive gene release surface will open a new avenue to enhance the endothelialization of blood-contacting devices.

Abstract
Gene therapy exerts powerful potential in the treatment of various diseases, such as overexpressing pro-angiogenic gene to accelerate angiogenesis and restore vascular flow of ischemic tissue. Tremendous efforts have been invested in developing gene carriers for high transfection efficiency, while little research has been devoted to synergistically expressing functional proteins via optimizing therapeutic genes. Actually, the amplified gene expression is the ultimate goal of gene delivery. Dual-gene co-delivery and coordinate expression become a "breach" of strengthened gene expression. Herein, we explored the synergistic effects on gene expression and pro-angiogenesis by two typical dual-gene delivery strategies to determine which one is more efficient. The physical mixing method used ZNF580 and VEGF165 plasmids with a 1/1 weight ratio (p1:1), and the other strategy involved chemically inserting ZNF580 and VEGF165 genes into one plasmid as a dual-gene co-expression plasmid (pZNF-VEGF). p1:1 and pZNF-VEGF were loaded by REDV-TAT-NLS-H12 carrier, a promising peptide carrier, to form corresponding dual-gene delivery systems. Both systems exhibited approximately similar size and zeta potential, guaranteeing almost the same cellular uptake. We comprehensively evaluated two delivery systems through gene expression at mRNA and protein levels and angiogenesis-related activities in vitro and in vivo. Interestingly, the pZNF-VEGF group showed a remarkably amplified synergistic effect in the expression of ZNF580 and VEGF165 genes in comparison with the p1:1 group. More importantly, the unexpected amplified synergistic effect of dual-gene co-expression plasmid was further verified for proliferation, migration, and angiogenesis in vitro and in vivo. Accordingly, we believed that the co-delivery of dual genes via constructing co-expression plasmids offers a better option for gene therapy, which can more effectively enhance the synergistic expression of target genes than the physical mixing method.

Abstract
Cardiovascular devices have been widely applied in the clinical treatment of cardiovascular diseases. However, poor hemocompatibility and slow endothelialization on their surface still exist. Numerous surface engineering strategies have mainly sought to modify the device surface through physical, chemical, and biological approaches to improve surface hemocompatibility and endothelialization. The alteration of physical characteristics and pattern topographies brings some hopeful outcomes and plays a notable role in this respect. The chemical and biological approaches can provide potential signs of success in the endothelialization of vascular device surfaces. They usually involve therapeutic drugs, specific peptides, adhesive proteins, antibodies, growth factors and nitric oxide (NO) donors. The gene engineering can enhance the proliferation, growth, and migration of vascular cells, thus boosting the endothelialization. In this review, the surface engineering strategies are highlighted and summarized to improve hemocompatibility and rapid endothelialization on the cardiovascular devices. The potential outlook is also briefly discussed to help guide endothelialization strategies and inspire further innovations. It is hoped that this review can assist with the surface engineering of cardiovascular devices and promote future advancements in this emerging research field.

Abstract
Diabetic foot ulcer (DFU) is a major complication of diabetes in the elderly population. The aim of this study was to investigate the potential mechanism of DFU at the molecular level and explore a feasible therapy for it. Using data from the Gene Expression Omnibus (GEO) database, we found that phosphatase and tensin homolog (PTEN) is differentially expressed between diabetic patients and those without diabetes. We also found that PTEN expression is regulated by glucose stimulation. In addition, decreased function of human umbilical vein endothelial cells (HUVECs) was found to be associated with reduction of PTEN. We identified microRNA-152-3p (miR-152-3p) to be a putative upstream negative regulator of PTEN, and in vivo and in vitro results indicated that miR-152-3p antagonist could restore HUVEC function and accelerate wound repair. Thus, miR-152-3p-induced downregulation of PTEN appears responsible for the delayed wound healing in DFU, and miR-152-3p inhibition may effectively accelerate wound repair, thereby providing a potential target for DFU therapy.
