The study of the insulin-producing pancreatic b-cells transcends the realm of basic biology because of their importance for the maintenance of glucose homeostasis. As their autoimmunemediated destruction or the impairment of their function cause diabetes, the pursuit of strategies for b-cell replenishment and/or replication is a major objective of regenerative medicine. Owing to their slow turn...
Objective: Perovskia abrotanoides Karel, belongs to the family Lamiaceae and grows wild alongside the mountainous roads inarid and cold climate of Northern Iran. The anti-tumor activity of P. abrotanoides root extract has been shown previously. This study was designed to examine in vitro anti-proliferative and pro-apoptotic effects of flower extract of P. abrotanoides on MCF-7 and Hela cell lin...
Background & Objectives: Breast cancer is the most common cancer and the second leading cause of cancer deaths among women. Obesity, hormones, and growth factors are the risk factors for this kind of cancer. One of the changes observed in patients suffering from breast cancer is the elevated Visfatin or nicotinamide phosphoribosyl transferase (NAMPT) in their tumor tissues and blood. The increa...
Introduction: Non-target radiation effects are damages and effects that occur without the need for direct radiation exposure in cells. Bystander signals cause non-targeted irradiation effect that has been defined as radiation responses in which non-irradiated cells exhibit irradiated effects as a result of signals from adjacent irradiated cells. In this study, the bystander ef...
Hepatitis B virus (HBV) is a serious global health problem. The development of a safe and effective vaccinewould help infection prevention. Previous hepatitis B vaccine production involved the isolation of the noninfectious particle from chronic HBV carriers. DNA recombinant technology has been used for vaccineproduction without having been contaminated with blood-born infectious ag...
Background: Recently, iron oxide nanoparticles have attracted attention in various diagnosis and treatment fields. The aim of the present study was to investigate the cytotoxicity of various concentrations and incubation times of dextran-coated iron oxide nanoparticles (DIONPs) on HeLa and MCF-7 cancerous cell lines. Methods: This in-vitro study was conducted at Pharmaceutical Sciences Researc...
مقدمه: وروتوکسین ها سمومی با ساختمان دو بخشی هستند که در پاتوژنز سویه های اشرشیا کولی انتروهموراژیک دخالت دارند. مطالعات اولیه درمان برخی تومورهای سرطانی و نیز بررسی اثر سیتوتوکسیسیته این سموم روی رده های توموری در شرایط محیط کشت (In Vitro) وحیوانات آزمایشگاهی نشان دهنده اثر بخشی آنهاست.این سموم به دلیل دارا بودن گیرنده های اختصاصی بر روی رده های توموری مطالعه شده به صورت انتخابی عمل می ...
Breast cancer is recognized as the most common cause of cancer deaths in women. So far, no definite treatment has been identified there is no certain cure for breast cancer. The Ooverexpression of interleukin-8 is associated with increased tumor growth and breast cancer metastasis. Hesperetin is a flavonone sub-group of flavonoids that is abundantly found in citrus fruits, including lemons and ...
