آپوپتوز و اثرات تنظیمی چرخه سلولی آدنوزین با تعدیل مسیرهای GLI-1 و ERK1 / 2 در سلولهای بنیادی سرطان پستان CD44 + و CD24−

Abstract Objectives Breast cancer stem cells (CSCs) are a small population of tumour cells with the ability of self-renewal and resistance to chemotherapy. Targeting CSCs is a promising strategy for treatment of cancer. A recent study demonstrated that adenosine receptor agonists inhibit glioblastoma CSCs proliferation. At present, the effect of adenosine on breast CSCs has […]

مقایسه سطح تورین پلاسما بین بیماران مبتلا به سرطان مری و افراد سالم

Abstract: s Background and Objectives: The incidence rate of esophageal cancer (EC) is high in north and northeast of Iran. Taurine is a sulfur-containing amino acid with a wide range of vital biological functions. The aim of this study was to compare plasma levels of taurine between patients with EC and healthy controls. Methods: Plasma […]

آگونیست گیرنده های آدنوزین A3 از طریق مسیرهای GLI-1 و ERK1 / 2 مانع زنده ماندن سلول های بنیادی سرطان پستان می شود

ABSTRACT Numerous studies have demonstrated the role of A3 adenosine receptor (A3AR) and signaling pathways in the multiple aspects of the tumor. However, there is a little study about the function of A3AR in the biological processes of cancer stem cells (CSCs). CSCs have a critical role in the maintenance and survival of breast cancer. […]

آگونیست گیرنده های آدنوزین A3 باعث توقف چرخه سلولی G1 از طریق مسیرهای Cyclin D و ۴ وابسته به سیکلین در رده های سلول OVCAR-3 و Caov-4

Abstract Aim of the study: The cell cycle, a vital process that involves in cells’ growth and division, lies at the heart of cancer. It has been shown that IB-MECA, an A3 adenosine receptor agonist inhibits the proliferation of cancer cells by inducing cell cycle arrest in several tumors. In this study, we evaluated the […]

نقش هموسیستئین در بیماری ها: یک مرور

ABSTRACT: Cardiovascular disease (CVD) is one of the most important causes of mortality worldwide. Several risk factors have been proposed to be associated with CVD. The main risk factors include family history, smoking, hypertension, history of diabetes, hyperlipidemia and obesity. However, new factors have been recently proposed to be associated with CVD. These include blood […]

مقایسه سطح سرمی استرانسیوم و آنتیموان در بیماران مبتلا به سرطان مری و افراد سالم

ABSTRACT Background And Objective Esophageal cancer is the third most common type of cancer in Iran. Studies on water, soil, grains, waste and sediments in Golestan Province have shown that the environmental concentrations of antimony and strontium are increased in areas with high incidence rate for cancer. The carcinogenic effects of strontium have been reported, […]

ارزیابی فعالیت LDH و ارتباط آن با سطوح فروکتوز در پلاسمای منی مردان نرموسپرمیک و استنوسپرمیک

ABSTRACT         Background and Objectives: sperm motility mainly depends on aerobic glycolysis, and lactate dehydrogenase (LDH) is a key enzyme in the last step of this process. On the other hand, fructose is considered as the main energy source for sperm motility. Therefore, this study aimed to evaluate the LDH activity and fructose levels and their […]

تعیین کمی آفلاتوکسین با کروماتوگرافی مایع با کارایی بالا در سیلوهای گندم در استان گلستان ، شمال ایران

Abstract Background: Aflatoxins are the most common mycotoxins that contaminate crops. They are produced by fungi such as Aspergillus flavus and Aspergillus parasiticus. Wheat (Tricitumaestivum) is one of the most important staple foods used in Iran, and the environmental conditions in the north of Iran are favorable to fungal growth. This study was designed in order to determine […]

پیش بینی محاسباتی اثرات پلی مورفیسم های تک نوکلئوتیدی ژن کد کننده سنتز اکسید نیتریک اندوتلیال انسانی

ABSTRACT           Background and Objective: Genetic variations in the gene encoding endothelial nitric oxide synthase (eNOS) enzyme affect the susceptibility to cardiovascular disease. Identification of the way these changes affect eNOS structure and function in laboratory conditions is difficult and time-consuming. Thus, it seems essential to perform bioinformatics studies prior to laboratory studies to find  the […]
