Abstract

Targeted drug delivery for primary brain tumors, particularly gliomas, is currently a promising approach to reduce patient relapse rates. The use of substitutable scaffolds, which enable the sustained release of clinically relevant doses of anticancer medications, offers the potential to decrease the toxic burden on the patient's organism while also enhancing their quality of life and overall survival. Upconversion nanoparticles (UCNPs) are being actively explored as promising agents for detection and monitoring of tumor growth, and as therapeutic agents that can provide isolated therapeutic effects and enhance standard chemotherapy. Our study is focused on the feasibility of constructing scaffolds using methacrylated hyaluronic acid with additional impregnation of UCNPs and the chemotherapeutic drug temozolomide (TMZ) for glioma treatment. The designed scaffolds have been demonstrated their efficacy as a drug and UCNPs delivery system for gliomas. Using the aggressive orthotopic glioma model in vivo, it was found that the scaffolds possess the capacity to ameliorate neurological disorders in mice. Moreover, upon intracranial co-implantation of the scaffolds and glioma cells, the constructs disintegrate into distinct segments, augmenting the release of UCNPs into the surrounding tissue and concurrently reducing postoperative damage to brain tissue. The use of TMZ in the scaffold composition contributed to restraining glioma development and the reduction of tumor invasiveness. Our findings unveil promising prospects for the application of photopolymerizable biocompatible scaffolds in the realm of neuro-oncology.

利用富含上转换纳米粒子和替莫唑胺的三维支架在正位小鼠模型中加强胶质瘤治疗。
目前,针对原发性脑肿瘤(尤其是胶质瘤)的靶向给药是降低患者复发率的一种很有前景的方法。使用可替代的支架可持续释放临床相关剂量的抗癌药物,从而有可能减轻患者机体的毒性负担,同时提高他们的生活质量和总体生存率。人们正在积极探索上转换纳米粒子(UCNPs),将其作为检测和监测肿瘤生长的有前途的药物,以及作为可提供独立治疗效果和增强标准化疗的治疗药物。我们的研究重点是利用甲基丙烯酸化透明质酸构建支架的可行性,并在支架中额外浸渍 UCNPs 和化疗药物替莫唑胺(TMZ),用于胶质瘤治疗。所设计的支架作为胶质瘤的药物和 UCNPs 给药系统,其疗效已得到证实。利用侵袭性正位胶质瘤体内模型,研究发现支架具有改善小鼠神经系统疾病的能力。此外,当支架和胶质瘤细胞共同植入颅内时,构建物会分解成不同的片段,从而增加 UCNPs 向周围组织的释放,同时减少术后对脑组织的损伤。在支架成分中使用 TMZ 有助于抑制胶质瘤的发展和降低肿瘤的侵袭性。我们的研究结果揭示了光聚合生物相容性支架在神经肿瘤学领域的应用前景。

期刊介绍: Frontiers in Chemistry is a high visiblity and quality journal, publishing rigorously peer-reviewed research across the chemical sciences. Field Chief Editor Steve Suib at the University of Connecticut is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to academics, industry leaders and the public worldwide. Chemistry is a branch of science that is linked to all other main fields of research. The omnipresence of Chemistry is apparent in our everyday lives from the electronic devices that we all use to communicate, to foods we eat, to our health and well-being, to the different forms of energy that we use. While there are many subtopics and specialties of Chemistry, the fundamental link in all these areas is how atoms, ions, and molecules come together and come apart in what some have come to call the “dance of life”. All specialty sections of Frontiers in Chemistry are open-access with the goal of publishing outstanding research publications, review articles, commentaries, and ideas about various aspects of Chemistry. The past forms of publication often have specific subdisciplines, most commonly of analytical, inorganic, organic and physical chemistries, but these days those lines and boxes are quite blurry and the silos of those disciplines appear to be eroding. Chemistry is important to both fundamental and applied areas of research and manufacturing, and indeed the outlines of academic versus industrial research are also often artificial. Collaborative research across all specialty areas of Chemistry is highly encouraged and supported as we move forward. These are exciting times and the field of Chemistry is an important and significant contributor to our collective knowledge.
