چکیده

پیشینه مطالعه و هدف: سرطان سینه، یکی شایع‌ترین سرطان‌ها و دومین عامل مرگ و میر در زنان به شمار می‌رود. هدف از این مطالعه، بررسی اثرات ضد سرطانی عصاره سیانوباکتریPhormidiumm animale با کمک آزمون MTT و ارزیابی بیان ژنی p53 در رده سلولی سرطان سینه می باشد.
روش مطالعه: در این مطالعه رده های سلولی سرطانی سینه (MCF-7) و نرمال (HEK293) تحت تیمار عصاره Phormidiumm animale با غلظت‌های مختلف 50، 100 و 200 میلی گرم در میلی‌لیتر طی زمان 24 ساعت قرار گرفتند. درصد زنده مانی سلول‌ها برروی رده‌های سلولی با کمک روش رنگ سنجی MTT ارزیابی شد. بیان کمی ژن P53 نسبت به ژن کنترل GAPDH با کمک تکنیک Real-time PCR بررسی شد.
نتایج: نتایج تست MTT نشان داد که عصاره P. animale، میزان زنده مانی سلول‌های سرطانی را نسبت به سلول‌های نرمال به طور معنی داری کاهش می دهد. همچنین، بیان ژن p53 بعد از تیمار با غلظت‌های 50، 100 و 200 میلی گرم بر میلی لیتر عصاره P. animale به ترتیب 34/3 ، 15/5 و 11/9 برابر نسبت به ژن کنترل افزایش یافت.
نتیجه گیری: نتایج این پژوهش نشان داد که عصاره سیانوباکتری P. animale توانایی کشتن سلول‌های سرطانی را دارد و این امر می‌تواند با کمک مرگ برنامه ریزی شده آپوپتوز با افزایش بیان ژن p53 در رده ی سلولی سرطانی سینه MCF-7 انجام گیرد.

چکیده [English]

Introduction and Aim: Breast Cancer is the most prevalent type of tumor and is also have second major death among women. The aim of the current study was to investigate the anticancer properties of Phormidiumm Animale cyanobacterium extract using MTT assay and through modulation of p53 gene expression in breast cancer cells.
Methods: In the current study, the breast cancer MCF-7 and normal HEK293 cell lines were treated with various concentrations of P. animale extract ranging 50, 100, 200 mg/mL for 24 hours. Cell viability was measured using MTT (3-(4, 5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) assay against cell lines. The gene expressions of p53 compared with GAPDH were measured using the real-time PCR method.
Results: The MTT results showed that P. animale significantly decreased the viability of cancer cells compared to normal cells in dose-dependent mode. Moreover, the mRNA levels of p53 were significantly increased from 3.34 in MCF-7 cells to 5.15 and 9.11 fold, respectively, following treatment with 50, 100, and 200 mg/mL P. animale extract.
Conclusion: The data suggest that P. animale extract can induce cytotoxicity and might modulate apoptosis by up-regulating p53 gene expression in human breast cancer MCF-7 cell line.
