Abstract

Circumvention of cancer drug resistance is one of the major investigations in nanomedicine. In this regard, nanotechnology-based drug delivery has offered various implications. However, protein-based nanocarriers have been a versatile choice compared to other nanomaterials, provided by their favorable characteristics and safety profiles. Specifically, albumin-based nanoparticles have been demonstrated to be an effective drug delivery system, owing to the inherent targeting modalities of albumin, through gp60- and SPARC-mediated receptor endocytosis. Furthermore, surface functionalization was exploited for active targeting, due to albumin's abundance of carboxylic and amino groups. Stimuli-responsive drug release has also been pertained to albumin nano-systems. Therefore, albumin-based nanocarriers could potentially overcome cancer drug resistance through bypassing drug efflux, enhancing drug uptake, and improving tumor accumulation. Moreover, albumin nanocarriers improve the stability of various therapeutic cargos, for instance, nucleic acids, which allows their systemic administration. This review highlights the recent applications of albumin nanoparticles to overcome cancer drug resistance, the nano-fabrication techniques, as well as future perspectives and challenges.

摘要

克服癌症耐药性是纳米医学的主要研究方向之一。在这方面,基于纳米技术的药物递送具有多种意义。然而,与其他纳米材料相比,基于蛋白质的纳米载体因其良好的特性和安全性而成为一种通用的选择。具体而言,基于白蛋白的纳米颗粒已被证明是一种有效的药物递送系统,这归因于白蛋白通过gp60和富含半胱氨酸的酸性分泌蛋白(SPARC)介导的受体胞吞作用所具有的内在靶向方式。此外,由于白蛋白富含羧基和氨基,表面功能化被用于主动靶向。刺激响应性药物释放也与白蛋白纳米系统有关。因此,基于白蛋白的纳米载体有可能通过绕过药物外排、增强药物摄取和改善肿瘤蓄积来克服癌症耐药性。此外,白蛋白纳米载体提高了各种治疗性货物(如核酸)的稳定性,使其能够进行全身给药。本综述重点介绍了白蛋白纳米颗粒在克服癌症耐药性方面的最新应用、纳米制造技术以及未来的前景和挑战。
