Epidemiologic studies have established that pregnancy has a bidirectional, time-dependent effect on breast cancer risk; a period of elevated risk is followed by a long-term period of protection. The purpose of the present study was to determine whether pregnancy and involution are associated with gene expression changes in the normal breast, and whether such changes are transient or persistent....
Background: The risk of thyroid disease has been increased during recent years; more than 200 million people are suffering from various types diseases. rate nodules in women is 4 times that men. Epidemiological findings and experimental evidence lesions suggest sex hormones, especially estrogen, may affect this gland its neoplasms. Objectives: Considering the prevalence benign malignant women, ...
BACKGROUND The strong male predominance in oesophageal adenocarcinoma (OAC) and Barrett's oesophagus (BO) continues to puzzle. Hormonal influence, e.g. oestrogen or oxytocin, might contribute. METHODS This genetic-epidemiological study pooled 14 studies from three continents, Australia, Europe, and North America. Polymorphisms in 3 key genes coding for the oestrogen pathway (receptor alpha (E...
Psoriasis is a genetically determined inflammatory skin disease. Although the transition from uninvolved into lesional skin is accompanied by changes in the expression of multiple genes, much less is known about the difference between uninvolved skin from psoriatic patients as opposed to skin from normal individuals. Multiple biochemical and morphological changes were reported decades ago in un...
مطالعات انجام شده روی مکانیسمهای تکوینی و تکاملی گلبولهای قرمز منجر به دستیابی بشر به مفاهیم پایه و مهمی در ارتباط با مکانیسمهای عمومی تنظیم بیان ژن وشکل گیری بافتها شده است. تمایز اختصاصی به رده ارتیروئید و هر رده دیگری، شدیداً وابسته به تنظیم در سطح بیان ژن و فاکتورهای کنترلی خاص نظیر سیتوکین ها، فاکتورهای نسخه برداری ویژه، عناصر کنترل کننده چرخه سلولی، تکثیر،آپوپتوز و عناصر سیگنالینگ داخل سلو...
BACKGROUND Lung cancer is the leading cause of cancer death in Brunei Darussalam, accounting for almost 20% of the total. The epidermal growth factor receptor (EGFR) is a member of the erbB family of tyrosine kinase receptor proteins, which includes c-erbb2(HER2/neu), erb-B3, and erb-B4. EGFR overexpression is found in a third of all epithelial cancers, often associated with a poor prognosis. ...
Two estrogen receptors (ERA and ERB) are found throughout the mammary gland. Evidence indicates that, while ERA transduces proliferation signals, ERB opposes this effect and is necessary for epithelial differentiation. Using mouse mammary epithelial cells, we have previously shown that activation of ERB opposes ERA-induced proliferation and increases apoptosis. Furthermore, stable knockdown of ...
The above article from Andrology, 'Impact of polymorphisms in the oestrogen receptors alpha and beta (ESR1, ESR2) genes on risk of vasculogenic erectile dysfunction' by M. R. Safarinejad, A. Taghva, N. Shafiei and S. Safarinejad published online on 20 May 2013 in Wiley Online Library has been retracted by agreement between the journal Editors-in-Chief, Douglas Carrell and Ewa Rajpert-De Meyts a...
Variability in the subfertile patient population excludes the possibility of a single approach to controlled ovarian stimulation (COS) covering all the requirements of a patient. Modern medical science has made great advances in the understanding and the development of new drugs, treatment options and quantitative methods that can identify single patient characteristics. Factors that reduce fol...
Prostate cancer is the most commonly diagnosed malignancy in men in developed countries. ErbB2, a tyrosine kinase receptor overexpressed in many human cancer types, contributes to prostate cancer progression by activating the androgen receptor in a steroid poor environment, thus promoting androgen-independent cell growth. The consequent development of hormone refractory tumors is a major obstac...
