چکیده
امروزه با پیشرفت نانوفن‌آوری، میتوان نانو موادی با عدد اتمی بالا، نظیر نانو ذرات طلا، را به روش‌های مختلفی به طور اختصاصی در سلول‌های توموری متمرکز کرد و از مزیت افزایش دز ناشی از مجاورت این عنصر دارای عدد اتمی بالا در کنار سلول‌های سرطانی به عنوان یک حساس‌کننده‌ی پرتویی بهره برد. در این پژوهش نانو ذرات طلا با قطر میانگین 50 نانومتر سنتز و با مولکول فولیک اسید یکی شد. این کمپلکس به مدت 24 ساعت و در غلظت‌های مختلف با سلول‌های MCF-7 گرماگذاری شده و میزان سمیّت‌زایی آن مورد مطالعه قرار گرفت. نتایج نشان داد که افزایش غلظت نانو ذرات طلا به بالاتر از حد مشخصی می‌تواند سلامت سلولی را تحت تأثیر قرار دهد. میزان حساس‌کنندگی پرتویی نانو ذرات طلا با غلظت 50 میکروگرم بر میلیلیتر در سلول‌های MCF-7 تحت 2 گری پرتو ایکس از یک دستگاه پرتو درمانی ارتوولتاژ در انرژی‌های مختلف 120, 180, 200 کیلو ولت بیشینه و با استفاده از روش MTT ارزیابی شد. اختلاف معناداری در میزان بقا در گروه‌های تابش‌دهی شده در حضور و عدم حضور نانو ذرات طلا مشاهده شد. بیشترین مقدار ضریب افزایش دز برابر با 1.34±0.03 برای باریکه‌ی پرتو ایکس 180 کیلو ولت بیشینه به دست آمد. یافته‌های این پژوهش این امکان را می‌دهد که با اعمال کاهش دزی به میزان یک سوم دز تجویزی، اثر مشابه‌ی، از آسیب سلولی، در سلول‌های سرطانی همزمان با محافظت بیش‌تر از بافت‌های سالم در معرض خطر، در مجاورت هدف ایجاد شود.

چکیده [English]
Recent dvances in nanotechnology have enabled us to accumulate high atomic-number nano-materials, such as gold nanoparticles (GNPs), in tumor cells selectively using different techniques and take the advantage of the dose enhancement factor resulting from the presence of such high-Z elements as the vicinity of cancerous cells as a radiosensitizer agent. In this research, the GNPs with an average diameter of 50nm were synthesized and conjugated with folic acid. Different concentrations of this nanoconjugate were incubated with MCF-7 cells for 24 hours and its cytotoxicity was investigated. The results showed that increasing the nanoconjugate concentration up to a critical amount, affects the cells viability. The radiosensitizing effect of the folate nanoconjugate, with a concentration of 50μg/mL, on the MCF-7 cells was assessed under 2Gy of x-ray radiation, generated by an orthhovoltage radiotherapy machine, at various energies of 120, 180, 200 kVp, using the MTT assay. Significant differences in the cell survival were noted among the groups exposed to x-ray radiation with and without the nanoconjugate. A maximum dose enhancement factor of 1.34±0.03 was obtained for the 180kVp X-ray beam. The findings enable us to decrease by one third of the prescribed dose while having the same level of damage to cancer cells. Also, this dose reduction results in lower exposure to the normal tissues located close to the target.
