Breast cancer incidence and mortality rates have increased exponentially during the last decade, particularly among female patients. Current therapies, including surgery and chemotherapy, have significant negative physical and mental impacts on patients. As a safer alternative, gene therapy utilising a therapeutic gene with the potential to treat various ailments is being considered. Delivery of the gene generally utilises viral vectors. However, immunological reactions and even mortality have been recorded as side effects. As a result, non-viral vectors, such as liposomes, a system composed of lipid bilayers formed into nanoparticles, are being studied. Liposomes have demonstrated tremendous potential due to their limitless ability to combine many functions into a system with desirable characteristics and functionality. This article discusses cationic, anionic, and neutral liposomes with their stability, cytotoxicity, transfection ability, cellular uptake, and limitation as a gene carrier suitable for gene therapy specifically for cancer. Due to the more practical approach of employing electrostatic contact with the negatively charged nucleic acid and the cell membrane for absorption purposes, cationic liposomes appear to be more suited for formulation for gene delivery and therapy for breast cancer treatment. As the other alternatives have numerous complicated additional modifications, attachments need to be made to achieve a functional gene therapy system for breast cancer treatment, which were also discussed in this review. This review aimed to increase understanding and build a viable breast cancer gene therapy treatment strategy.
在过去的十年中,乳腺癌的发病率和死亡率呈指数级增长,特别是在女性患者中。目前的治疗方法,包括手术和化疗,对患者的身体和精神都有很大的负面影响。作为一种更安全的选择,利用具有治疗各种疾病潜力的治疗基因的基因治疗正在被考虑。基因的传递通常利用病毒载体。然而,免疫反应甚至死亡已经被记录为副作用。因此,正在研究非病毒载体,如脂质体,一种由形成纳米颗粒的脂质双层组成的系统。由于其将许多功能结合到具有理想特性和功能的系统中的无限能力,脂质体显示出了巨大的潜力。本文讨论了阳离子、阴离子和中性脂质体及其稳定性、细胞毒性、转染能力、细胞摄取以及作为基因载体用于癌症基因治疗的局限性。由于阳离子脂质体采用与带负电荷的核酸和细胞膜静电接触的更实用的方法进行吸收,因此似乎更适合用于基因传递和乳腺癌治疗的制剂。由于其他替代方案需要进行许多复杂的额外修饰,需要进行附加来实现用于乳腺癌治疗的功能性基因治疗系统,这在本综述中也进行了讨论。本综述旨在提高对乳腺癌基因治疗的理解并建立可行的治疗策略。
