Background: The use of medicinal herbs in traditional medicine has been important and many of these plants have antioxidant, anti-inflammatory, antimicrobial and anti-cancer effects. Objective: The aim of this study was to evaluate the antibacterial and anti-cancer effects of Artemisia turcomanica extract on gastric cancer cell line (AGS) and its effect on expression of cyclin D1 and cyclin E g...
objective(s):intermittent hypoxia (ih), caused by obstructive sleep apnea (osa), could cause hippocampus or neuron damage through multiple signaling pathways, while the underlying mechanisms are still unclear. thus, the present study aimed to explore the effect of ih on the biological functions of microglia cells. materials and methods:cell proliferation of bv2 cells after exposure to ih were o...
پیش زمینه و هدف: سرطان پستان شایع ترین سرطان در زنان می باشد و طبق مطالعات انجام شده در ایران شروع سرطان پستان حداقل یک دهه زودتر از شروع آن در کشورهای پیشرفته است. در سال های اخیر توجه زیادی به استفاده از بیومارکرها در پیشگویی پاسخ به درمان و پروگنوز بیماران شده است. مواد و روش ها: از فروردین ماه سال 1383 تا بهمن 1387 تعداد 38 بیمار که با تشخیص کارسینوم داکتال پستان در بیمارستان امام خمینی ارو...
objective: n-nitroso-n-methylurea (nmu) induces breast cancer in rodents, particularly in rats. this model of breast cancer is very similar to human breast cancer. as a continuation of our recent work, we investigated the expressions of cyclin d1 and p21 in nmu-induced breast cancer of wistar albino rats. materials and methods: in this experimental study, mammary carcinoma was induced in female...
Objective(s):Intermittent hypoxia (IH), caused by obstructive sleep apnea (OSA), could cause hippocampus or neuron damage through multiple signaling pathways, while the underlying mechanisms are still unclear. Thus, the present study aimed to explore the effect of IH on the biological functions of microglia cells. Materials and Methods:Cell proliferation of BV2 cells after exposure to IH were o...
Objective(s): Hepatocellular carcinoma (HCC) is one of the most significant health condition around the world. As the only curative therapies, liver transplantation and surgical resection are the clinical treatments of HCC. Due to the systemic toxicity and severe side effects of these treatments, it is vital to establish new therapeutic approaches. The present study ai...
Introduction: Proliferation of cancer cells and the potential of metastasis depend on the activity of different biomarkers such as proliferative ones. Proliferative biomarkers including ki-67, cyclin E1, cyclin D1, p27, and p21 were analyzed through immunohistochemistry (IHC) in previous studies. Methods: The current study aimed at investigating the utilizing role of RT-PCR in studying prolife...

Background: Hepatocellular carcinoma is the most common primary malignant tumor of the liver. The effect of some genes especially those involved in cell cycle regulation have been shown in the development of this cancer in several studies but there are some controversies about them yet. Materials and methods: The paraffin-embedded tissue samples of 25 patients (18 males and 7 females) with hep...
Background: Researchers argue that supplements are somewhat capable of influencing the lung tissue exposed to smoking carcinogens through cell cycle. Cyclin D1 is a gene involved in cell cycle. Objective: This study aimed to investigate the effects of 12-week injection of Nigella sativa nano-capsule on the expression of Cyclin D1 of the lung tissue of the rats receiving exposure to Nicotine-Der...
