Biofabrication of bimetallic selenium@zinc nanoparticles using Champia parvula aqueous extract: Investigation of anticancer activity and its apoptosis induction. Biochem Biophys Res Commun 2024; 733:150417. [PMID: 39047428 DOI: 10.1016/j.bbrc.2024.150417] [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: 03/30/2024] [Revised: 07/15/2024] [Accepted: 07/16/2024] [Indexed: 07/27/2024]
Abstract
Selenium@zinc nanoparticles, or Se@Zn NPs, are extensively employed in various environmental, industrial and biological domains. However, the biological potential of Se@Zn NPs has not been thoroughly investigated. This study focused on fabricating Se@Zn NPs from algae using an aqueous extract of Champia parvula seaweed. Analytical techniques were used to describe the successfully synthesized Se@Zn NPs. In addition, a biological function analysis of the Se@Zn NPs was conducted. The Ultraviolet-visible spectroscopy (UV-vis) spectrum showed a specific absorbance peak for the Se@Zn NPs at 350-400 nm. The biomolecules involved in forming Se@Zn NPs were identified by their potential functional groups, as revealed by Fourier transform infrared spectroscopy (FTIR). By scanning electron microscopy (SEM) and transmission electron microscopy (TEM), Se@Zn NPs were shown to be spherical and to have a diameter range of 100-200 nm. NPs with a crystallite diameter of 54.8 nm and chemical compositions of zinc and selenium (1:1.5 ratio) were revealed by X-ray diffraction analysis (XRD) and energy dispersive x-ray spectroscopy (EDS). IC50 values were determined for the anticancer activity against A549, MCF-7 and HeLa cells. Cell morphological changes in fluorescence microscopy and apoptosis mechanisms by flow cytometry analysis were investigated, which show that Se@Zn NPs induced apoptosis in various cancer cells. DNA fragmentation and ROS levels were studied by fluorescence microscopy. In conclusion, conditions required for therapeutic and preventative applications may be met by the green synthesis of Se@Zn NPs.

Abstract
Acute myocardial infarction (AMI) causes acute cardiac cell death when oxygen supply is disrupted. Improving oxygen flow to the damaged area could potentially achieve the to prevent cell death and provide cardiac regeneration. Here, we describe the production of oxygen-producing injectable bio-macromolecular hydrogels from natural polymeric components including gelatin methacryloyl (GelMA), hyaluronic acid (HA) loaded with catalase (CAT). Under hypoxic conditions, the O2-generating hydrogels (O2 (+) hydrogel) encapsulated with Mesenchymal stem cells (MSCs)-derived-exosomes (Exo- O2 (+) hydrogel) released substantial amounts of oxygen for >5 days. We demonstrated that after 7 days of in vitro cell culture, exhibits identical production of paracrine factors compared to those of culture of rat cardiac fibroblasts (RCFs), rat neonatal cardiomyocytes (RNCs) and Human Umbilical Vein Endothelial Cells (HUVECs), demonstrating its ability to replicate the natural architecture and function of capillaries. Four weeks after treatment with Exo-O2 (+) hydrogel, cardiomyocytes in the peri-infarct area of an in vivo rat model of AMI displayed substantial mitotic activity. In contrast with infarcted hearts treated with O2 (-) hydrogel, Exo- O2 (+) hydrogel infarcted hearts showed a considerable increase in myocardial capillary density. The outstanding therapeutic advantages and quick, easy fabrication of Exo- O2 (+) hydrogel has provided promise favourably for potential cardiac treatment applications.

Abstract
Magnetic oxygen-loaded nanodroplets (MOLNDs) are a promising class of nanomaterials dually sensitive to ultrasound and magnetic fields, which can be employed as nanovectors for drug delivery applications, particularly in the field of hypoxic tissue treatment. Previous investigations were primarily focused on the application of these hybrid systems for hyperthermia treatment, exploiting magnetic nanoparticles for heat generation and nanodroplets as carriers and ultrasound contrast agents for treatment progress monitoring. This work places its emphasis on the prospect of obtaining an oxygen delivery system that can be activated by both ultrasound and magnetic fields. To achieve this goal, Fe3O4 nanoparticles were employed to decorate and induce the magnetic vaporization of OLNDs, allowing oxygen release. We present an optimized method for preparing MOLNDs by decorating nanodroplets made of diverse fluorocarbon cores and polymeric coatings. Furthermore, we performed a series of characterizations for better understanding how magnetic decoration can influence the physicochemical properties of OLNDs. Our comprehensive analysis demonstrates the efficacy of magnetic stimulation in promoting oxygen release compared to conventional ultrasound-based methods. We emphasize the critical role of selecting the appropriate fluorocarbon core and polymeric coating to optimize the decoration process and enhance the oxygen release performance of MOLNDs.

Abstract
Biomedicine and tissue regeneration have made significant advancements recently, positively affecting the whole healthcare spectrum. This opened the way for them to develop their applications for revitalizing damaged tissues. Thus, their functionality will be restored. Cardiac tissue engineering (CTE) using curative procedures that combine biomolecules, biomimetic scaffolds, and cells plays a critical part in this path. Stimuli-responsive hydrogels (SRHs) are excellent three-dimensional (3D) biomaterials for tissue engineering (TE) and various biomedical applications. They can mimic the intrinsic tissues' physicochemical, mechanical, and biological characteristics in a variety of ways. They also provide for 3D setup, adequate aqueous conditions, and the mechanical consistency required for cell development. Furthermore, they function as competent delivery platforms for various biomolecules. Many natural and synthetic polymers were used to fabricate these intelligent platforms with innovative enhanced features and specialized capabilities that are appropriate for CTE applications. In the present review, different strategies employed for CTE were outlined. The light was shed on the limitations of the use of conventional hydrogels in CTE. Moreover, diverse types of SRHs, their characteristics, assembly and exploitation for CTE were discussed. To summarize, recent development in the construction of SRHs increases their potential to operate as intelligent, sophisticated systems in the reconstruction of degenerated cardiac tissues.

Abstract
Cancer is a leading cause of death worldwide, accounting for an estimated 10 million deaths by 2020. Over the decades, various strategies for tumor therapy have been developed and evaluated. Photodynamic therapy (PDT) has attracted increasing attention due to its unique characteristics, including low systemic toxicity and minimally invasive nature. Despite the excellent clinical promise of PDT, hypoxia is still the Achilles' heel associated with its oxygen-dependent nature related to increased tumor proliferation, angiogenesis, and distant metastases. Moreover, PDT-mediated oxygen consumption further exacerbates the hypoxia condition, which will eventually lead to the poor effect of drug treatment and resistance and irreversible tumor metastasis, even limiting its effective application in the treatment of hypoxic tumors. Hypoxia, with increased oxygen consumption, may occur in acute and chronic hypoxia conditions in developing tumors. Tumor cells farther away from the capillaries have much lower oxygen levels than cells in adjacent areas. However, it is difficult to change the tumor's deep hypoxia state through different ways to reduce the tumor tissue's oxygen consumption. Therefore, it will become more difficult to cure malignant tumors completely. In recent years, numerous investigations have focused on improving PDT therapy's efficacy by providing molecular oxygen directly or indirectly to tumor tissues. In this review, different molecular oxygen supplementation methods are summarized to alleviate tumor hypoxia from the innovative perspective of using supplemental oxygen. Besides, the existing problems, future prospects and potential challenges of this strategy are also discussed.

Abstract
Cardiovascular diseases caused by ischemia are attracting considerable attention owing to its high morbidity and mortality worldwide. Although numerous agents with cardioprotective benefits have been identified, their clinical outcomes are hampered by their low bioavailability, poor drug solubility, and systemic adverse effects. Advances in nanoscience and nanotechnology provide a new opportunity to effectively deliver drugs for treating ischemia-related diseases. In particular, cardiac ischemia leads to a characteristic pathological environment called an ischemic microenvironment (IME), significantly different from typical cardiac regions. These remarkable differences between ischemic sites and normal tissues have inspired the development of stimuli-responsive systems for the targeted delivery of therapeutic drugs to damaged cardiomyocytes. Recently, many biomaterials with intelligent properties have been developed to enhance the therapeutic benefits of drugs for the treatment of myocardial ischemia. Strategies for stimuli-responsive drug delivery and release based on IME include reactive oxygen species, pH-, hypoxia-, matrix metalloproteinase-, and platelet-inspired targeting strategies. In this review, state-of-the-art IME-responsive biomaterials for the treatment of myocardial ischemia are summarized. Perspectives, limitations, and challenges are also discussed for the further development of innovative and effective approaches to treat ischemic diseases with high effectiveness and biocompatibility.

Abstract
In the case of serious cardiovascular diseases, such as refractory heart failure, heart transplantation is the only possible intervention. Currently, the modes of organ transport in hypothermic cardioplegic solution do not allow the implantation of the heart beyond 4-5 hours from the explant. The heart being an organ with a greater consumption of oxygen and high metabolism than the brain, its transport in hypothermic cardioplegic solutions presents critical issues in terms of time and conservation. An ambitious goal of many researchers and clinicians is to minimize the hypoxia of the explanted heart and extend the permanence time in cardioplegic solution without damage from hypoxia. Adequately oxygenating the explanted organs may extend the usability time of the explanted organ. This challenge has been pursued for years with approaches that are often expensive, risky, and/or difficult to use. We propose to consider oxygenated nanocarriers realizing oxygen for a long time. In this way, it will also be possible to use organs from distant countries with respect to the recipient, thus exceeding the canonical 4-5 hours tolerated up to now. In addition to the lack of oxygen, the transplanted organ can undergo the accumulation of catabolites due to the lack of perfusion during transport. Therefore, nanocarriers can also be perfused in adequate solution during organ transportation. A better oxygenation improving the postoperative recovery of the transplanted heart will improve the recipient's quality of life.

Abstract
Myocardial infarction (MI), triggered by blockage of a coronary artery, remains the most common cause of death worldwide. After MI, the capability of providing sufficient blood and oxygen significantly decreases in the heart. This event leads to depletion of oxygen from cardiac tissue and consequently leads to massive cardiac cell death due to hypoxemia. Over the past few decades, many studies have been carried out to discover acceptable approaches to treat MI. However, very few have addressed the crucial role of efficient oxygen delivery to the injured heart. Thus, various strategies were developed to increase the delivery of oxygen to cardiac tissue and improve its function. Here, we have given an overall discussion of the oxygen delivery mechanisms and how the current technologies are employed to treat patients suffering from MI, including a comprehensive view on three major technical approaches such as oxygen therapy, hemoglobin-based oxygen carriers (HBOCs), and oxygen-releasing biomaterials (ORBs). Although oxygen therapy and HBOCs have shown promising results in several animal and clinical studies, they still have a few drawbacks which limit their effectiveness. More recent studies have investigated the efficacy of ORBs which may play a key role in the future of oxygenation of cardiac tissue. In addition, a summary of conducted studies under each approach and the remaining challenges of these methods are discussed.

Abstract
Adipose-derived stem cells (ADSCs) treatment offers support to new methods of transporting baseline cell protein endothelial cells in alginate (A)/silk sericin (SS) lamellar-coated antioxidant system (ASS@L) to promote acute myocardial infarction. In the synthesized frames of ASS, the ratio of fixity modules, pores, the absorption and inflammation was detected at ka (65ka), 151 ± 40.12 μm, 92.8%, 43.2 ± 2.58 and 30.10 ± 2.1. In this context, ADSC-ASS@L was developed and the corresponding material was stable and physically chemical for the development of cardiac regenerative applications. ADSC-ASS@L injectable hydrogels in vitro examination demonstrated higher cell survival rates and pro-angiogenic and pro-Inflammatory expression factors, demonstrating the favorable effect of fractional ejections, fibre-areas, and low infracture vessel densities. In successful cardiac damage therapy in acute myocardial infarction the innovative ADSC injection hydrogel approach may be helpful. The approach could also be effective during coronary artery hypertrophy for successful heart damage treatment.

Abstract
The reconstruction of blood perfusion is a crucial therapeutic method to save and protect cardiac function after acute myocardial infarction (AMI). The activation of the hepatocyte growth factor precursor (pro-HGF) has a significant effect on promoting angiogenesis and antiapoptosis. The oxygen/glucose deprivation (OGD) caused by AMI could induce vascular adventitia fibroblasts to differentiate into myofibroblasts and secrete the pro-HGF. Meanwhile, the specific Met receptor of the hepatocyte growth factor (HGF) is upregulated in endothelial cells during AMI. However, the poor prognosis of AMI suggests that the pro-HGF is not effectively activated. Improving the activation efficiency of the pro-HGF may play a positive role in the treatment of AMI. Herein, we designed supramolecular nanofibers self-assembled by compound 1 (Comp.1, Nap-FFEG-IVGGYPWWMDV), which can strongly activate the pro-HGF and initiate HGF-Met signaling. Studies have proven that Comp.1 possesses a better ability to activate the pro-HGF to perform antiapoptosis and pro-angiogenesis. In vivo results have confirmed that the retention time of Comp.1 and its accumulation in the infarct area of the heart are promoted. Moreover, Comp.1 plays an effective role in promoting angiogenesis in the marginal area of AMI, reducing myocardial fibrosis, and protecting cardiac function. Herein, we will optimize the structure of bioactive peptides through supramolecular self-assembly and amplify their therapeutic effect by improving their efficiency, providing a new strategy for the therapy of AMI.
