Abstract

OBJECTIVE

Cancer or neoplasm is a cosmopolitan catastrophe that results in more than 20 million new cases and 10 million deaths every year. Some factors lead to carcinogenesis like infectious diseases. Parasites like , by its components, could modulate the cancer system by inducing apoptosis. The objective of this investigation is to assess the potential of peptides derived from in combating cancer by examining their effects on Caco-2, Hep-G2, and HT29 cell lines.

MATERIALS AND METHODS

Candidate peptide by its similarity to anticancer compounds was predicted through the computer-based analysis/platform. The impact of the peptide on cell viability, cell proliferation, and gene expression was evaluated through the utilization of MTT assay, flow cytometry, and real-time polymerase chain reaction (PCR) methodologies.

RESULTS

The cell viability rate exhibited a significant decrease (p < 0.001) across all cell lines when exposed to a concentration of ≤160 μg. Within the 48-hour timeframe, the half maximal inhibitory concentration (IC) for HT29 and Hep-G2 cell lines was determined to be 107.2 and 140.6 μg/mL, respectively. Notably, a marked decrease in the expression levels of and genes was observed in both the Hep-G2 and HT29 cell lines.

CONCLUSION

These findings indicate that the peptide affected cancer cell mortality and led to changes in the expression of genes associated with apoptosis.

摘要

目的

癌症或肿瘤是一场全球性的灾难,每年导致超过2000万新发病例和1000万人死亡。一些因素如传染病会导致致癌作用。某些寄生虫,就其成分而言,可通过诱导细胞凋亡来调节癌症系统。本研究的目的是通过检测源自该寄生虫的肽对Caco - 2、Hep - G2和HT29细胞系的影响,评估其抗癌潜力。

材料与方法

通过基于计算机的分析平台,根据其与抗癌化合物的相似性预测候选肽。利用MTT法、流式细胞术和实时聚合酶链反应(PCR)方法评估该肽对细胞活力、细胞增殖和基因表达的影响。

结果

当暴露于浓度≤160μg时,所有细胞系的细胞活力率均显著下降(p < 0.001)。在48小时内,HT29和Hep - G2细胞系的半数最大抑制浓度(IC)分别确定为107.2和140.6μg/mL。值得注意的是,在Hep - G2和HT29细胞系中均观察到某些基因的表达水平显著下降。

结论

这些发现表明该寄生虫肽影响癌细胞死亡率,并导致与细胞凋亡相关的基因表达发生变化。
