In spite of all the efforts and researches on anticancer therapeutics, an absolute treatment is still a myth. Therefore, it is necessary to utilize novel technologies in order to synthesize smart multifunctional structures. In this study, for the first time, we have evaluated the anticancer effects of BCc1 nanocomplex by vitro and in vivo studies, which is designed based on the novel nanochelating technology.
Human breast adenocarcinoma cell line (MCF-7) and mouse embryonic fibroblasts were used for the in vitro study. Antioxidant potential, cell toxicity, apoptosis induction, and CD44 and CD24 protein expression were evaluated after treatment of cells with different concentrations of BCc1 nanocomplex. For the in vivo study, mammary tumor-bearing female Balb/c mice were treated with different doses of BCc1 and their effects on tumor growth rate and survival were evaluated.
BCc1 decreased CD44 protein expression and increased CD24 protein expression. It induced MCF-7 cell apoptosis but at the same concentrations did not have negative effects on mouse embryonic fibroblasts viability and protected them against oxidative stress. Treatment with nanocomplex increased survival and reduced the tumor size growth in breast cancer-bearing balb/c mice.
These results demonstrate that BCc1 has the capacity to be assessed as a new anticancer agent in complementary studies.
尽管在抗癌治疗方面付出了诸多努力并进行了大量研究,但彻底治愈癌症仍是一个神话。因此,有必要利用新技术来合成智能多功能结构。在本研究中,我们首次通过体外和体内研究评估了基于新型纳米螯合技术设计的BCc1纳米复合物的抗癌效果。
体外研究使用人乳腺癌细胞系(MCF - 7)和小鼠胚胎成纤维细胞。用不同浓度的BCc1纳米复合物处理细胞后,评估其抗氧化能力、细胞毒性、凋亡诱导以及CD44和CD24蛋白表达。体内研究中,用不同剂量的BCc1处理荷乳腺肿瘤的雌性Balb/c小鼠,并评估其对肿瘤生长速率和存活率的影响。
BCc1降低了CD44蛋白表达,增加了CD24蛋白表达。它诱导MCF - 7细胞凋亡,但在相同浓度下对小鼠胚胎成纤维细胞活力没有负面影响,并保护它们免受氧化应激。纳米复合物处理提高了荷乳腺癌的Balb/c小鼠存活率并减小了肿瘤大小。
这些结果表明,BCc1有能力在补充研究中作为一种新型抗癌剂进行评估。
