The aim of the present research is to elucidate the anti-oxidant and anti-tumor activities of the mucin extracted from Ereminia desertorum snails´ mucus against two types of tumor cell lines; human colon adenocarcinoma (CACO-2) cells and human hepatoma (HepG-2) cells.
Both cell lines were treated with Ereminia desertorum snails´ mucin and the oxidative markers were measured in culture media and cells by biochemical and gene expression analysis using RT-PCR. The tumor suppressor gene expression was also evaluated using RT-PCR.
The culture media of HepG-2 or CACO-2 cells treated with the extract have high significant increased levels of catalase, SOD, GSH and total antioxidants. Apart from SOD in CACO-2 cells that didn't differ from untreated cells. Also, Gene expression levels (2^-ddct) of the antioxidant markers in HepG-2 cells; GSTA-1, catalase, SOD, and GPx increased in mucin- treated cells. Also, these antioxidant genetic markers were up-regulated in CACO-2 cells by treatment with mucin extract. Gene expression levels (2^-ddct) of tumor suppression genes (p53, Rb, APC, and PTEN) in both HepG-2 and CaCO-2 cells were increased in mucin extract-treated cells.
The present study highlighted the anti-oxidant and the anti-cancer activities of the mucin extracted from E. desertorum snails´ mucus that could attract attention to such natural product as a possible source of therapeutic compounds against liver and colon cancers.
本研究旨在阐明从荒漠凹顶蛤黏液中提取的黏蛋白对两种肿瘤细胞系(人结肠腺癌(CACO-2)细胞和人肝癌(HepG-2)细胞)的抗氧化和抗肿瘤活性。
用荒漠凹顶蛤黏液处理两种细胞系,通过生化和 RT-PCR 基因表达分析在培养物和细胞中测量氧化标记物。还使用 RT-PCR 评估肿瘤抑制基因的表达。
用提取物处理的 HepG-2 或 CACO-2 细胞的培养基中,过氧化氢酶、SOD、GSH 和总抗氧化剂的水平显著升高。除 CACO-2 细胞中的 SOD 与未处理的细胞没有差异外。此外,HepG-2 细胞中抗氧化标记物的基因表达水平(2^-ddct);GSTA-1、过氧化氢酶、SOD 和 GPx 在黏蛋白处理的细胞中增加。此外,用黏蛋白提取物处理 CACO-2 细胞也上调了这些抗氧化遗传标记物。HepG-2 和 CaCO-2 细胞中肿瘤抑制基因(p53、Rb、APC 和 PTEN)的基因表达水平(2^-ddct)在黏蛋白提取物处理的细胞中增加。
本研究强调了从荒漠凹顶蛤黏液中提取的黏蛋白的抗氧化和抗肿瘤活性,这可能引起人们对这种天然产物的关注,将其作为治疗肝癌和结肠癌的潜在化合物的来源。
