Abstract Introduction Clinoptilolite has antiviral, antibacterial, anti-inflammatory, antidiabetic, and anticancer properties due to its biological activities. In various cancer cell culture studies, it has been reported effective against tumour cells and gave positive results in treatment of various tumours in dogs. No study was found on the effects of the nanoparticulate form, nanoclinoptilolite, on cancer cells. The aim of this study was to determine its cytotoxic and apoptotic effects in canine osteosarcoma (OSA) cell culture. Material and Methods Doses at 50% inhibitory concentration were determined by measuring the dose- and duration-dependent cytotoxicity of nanoclinoptilolite on canine D-17 osteosarcoma cells by methylthiazol tetrazolium (MTT) test for 24 h, 48 h, and 72 h. Murine caspase-3 and -7 activity and expression levels of the BAX and BCL2 genes were measured using RT-PCR to investigate the apoptotic effect. Results Nanoclinoptilolite decreased cell viability and induced caspase-3- and -7-mediated apoptosis in treated canine OSA cells. Furthermore, its application to canine OSA cells downregulated the expression of BCL2 and upregulated the expression of proapoptotic BAX. Conclusion Clinoptilolite, which was previously demonstrated to have anticancer properties, decreased cell viability effectively and rapidly and increased the apoptotic cell ratio in a novel use in nanoparticle form, exhibiting this effect by increasing the BAX/BCL2 ratio.

纳米斜发沸石对犬骨肉瘤细胞系的细胞毒和凋亡作用

摘要 引言斜发沸石由于其生物活性而具有抗病毒、抗菌、抗炎、抗糖尿病和抗癌的特性。在各种癌细胞培养研究中,据报道它对肿瘤细胞有效,并在治疗狗的各种肿瘤方面取得了积极成果。没有发现关于纳米颗粒形式纳米斜发沸石对癌细胞的影响的研究。本研究的目的是确定其在犬骨肉瘤 (OSA) 细胞培养中的细胞毒性和凋亡作用。材料和方法 通过甲基噻唑四唑 (MTT) 试验 24 小时、48 小时和 72 小时,通过测量纳米斜发沸石对犬 D-17 骨肉瘤细胞的剂量和持续时间依赖性细胞毒性来确定 50% 抑制浓度的剂量。使用 RT-PCR 测量小鼠 caspase-3 和 -7 活性以及 BAX 和 BCL2 基因的表达水平以研究细胞凋亡作用。结果纳米斜发沸石降低了处理过的犬 OSA 细胞的细胞活力并诱导了 caspase-3 和 -7 介导的细胞凋亡。此外,它在犬 OSA 细胞中的应用下调了 BCL2 的表达并上调了促凋亡 BAX 的表达。结论 斜发沸石以前被证明具有抗癌特性,在纳米颗粒形式的新用途中有效且快速地降低细胞活力并增加凋亡细胞比率,通过增加 BAX/BCL2 比率来表现这种效果。结果纳米斜发沸石降低了处理过的犬 OSA 细胞的细胞活力并诱导了 caspase-3 和 -7 介导的细胞凋亡。此外,它在犬 OSA 细胞中的应用下调了 BCL2 的表达并上调了促凋亡 BAX 的表达。结论 斜发沸石以前被证明具有抗癌特性,在纳米颗粒形式的新用途中有效且快速地降低细胞活力并增加凋亡细胞比率,通过增加 BAX/BCL2 比率来表现这种效果。结果纳米斜发沸石降低了处理过的犬 OSA 细胞的细胞活力并诱导了 caspase-3 和 -7 介导的细胞凋亡。此外,它在犬 OSA 细胞中的应用下调了 BCL2 的表达并上调了促凋亡 BAX 的表达。结论 斜发沸石以前被证明具有抗癌特性,在纳米颗粒形式的新用途中有效且快速地降低细胞活力并增加凋亡细胞比率,通过增加 BAX/BCL2 比率来表现这种效果。
