基于镁铝水滑石纳米片载药系统的研制并应用于癌症细胞的治疗
evelopment of drug delivery system based on magnesium aluminum hydrotalcite nanoparticles and its application in the treatment of cancer cells.
p53基因编码出的p53蛋白,作为一种重要的肿瘤抑制因子,在预防肿瘤的发生过程中起到了关键作用。突变型p53(Mutp53)丧失了原先的抑癌活性,却能促进肿瘤细胞的生长、增殖、浸润、转移等。此外,有研究表明Mutp53需要与HSP90形成分子伴侣复合物来维持其蛋白结构稳定性。基于此,我们提出利用无机纳米复合材料(MgAl-LDH)将具有高催化活性的葡萄糖氧化酶(GOx)递送至Mutp53型肿瘤细胞中,通过催化分解葡萄糖,降低胞内ATP的供应。结果表明,此纳米复合材料具有均一性、稳定性,能有效的进入细胞并成功实现溶酶体逃逸,并对Mutp53型细胞系产生明显的杀伤。该方法对基于Mutp53型癌细胞的治疗提供了一种新颖和有前途的治疗手段。
he p53 protein encoded by the Tp53 gene, as an important tumor suppressor, plays a key role in preventing the occurrence of tumors.Mutant p53(Mutp53)can promote the growth, proliferation, invasion and metastasis of tumor cells while losing the original anti-cancer activity.In addition, studies have shown that Mutp53 needs to form a molecular chaperone complex with HSP90 to maintain its protein structure stability. Therefore, we propose to deliver a highly catalytically active Glucose oxidase (GOx) by inorganic nanoparticles(MgAl-LDH)into Mutp53 tumor cells to reduce the supply of intracellular ATP by catalytically decomposing Glucose. The results showed that the nanoparticles was homogeneous and stable and could effectively enter the cell and successfully achieve lysosome escape and cause obvious killing to the Mutp53 cells. This method provides a novel and promising therapeutic approach for the treatment of cancer cells based on Mutp53 type.
