Background: Polycystic ovary syndrome (PCOS) has taken the prime position as an endocrine disease in women of reproductive age and is estimated to affect 2.2–22.5% worldwide Indian it ranges from 9% 12%. The primary defects that cause PCOS still remains unknown. A lot genetic factors not excluding polymorphisms mutations multiple genes have been linked with PCOS, exact mechanisms which might be...

The human cytochrome P450 3A subfamily of enzymes is involved in the metabolism of steroid hormones, carcinogens, and many drugs. A cytosine-to-guanine polymorphism in CYP3A43 results in a proline-to-alanine substitution at codon 340. Although the functional significance of this polymorphism is unknown, we postulate that the substitution of proline, an A-imino acid, with alanine, an amino acid,...

INTRODUCTION AND OBJECTIVES Previous studies angiotensin-converting enzyme gene insertion/deletion polymorphism ACE (I/D), angiotensinogen gene polymorphism, and angiotensin II AT1 receptor polymorphism in relation to coronary heart disease controversial results. This study was designed to analyze the association between these gene polymorphisms and the first coronary event in individuals resid...

The human cytochrome P450 3A subfamily of enzymes is involved in the metabolism of steroid hormones, carcinogens, and many drugs. A cytosine-to-guanine polymorphism in CYP3A43 results in a proline-to-alanine substitution at codon 340. Although the functional significance of this polymorphism is unknown, we postulate that the substitution of proline, an alpha-imino acid, with alanine, an amino a...

BACKGROUND Melanoma Inhibitory Activity 3 regulates the plasma level of LDL cholesterol. The c.3169 + 315G > A single-nucleotide polymorphism of the MIA3 gene has been reported to be associated with serum coronary artery disease (CAD). However, there have been no studies analyzing the association of this polymorphism with CAD in Iranian individuals with CAD. OBJECTIVES Therefore, in the prese...

Essential hypertension is considered a multifactorial trait resulting from a combination of environmental and genetic factors. The angiotensin II type 1 receptor mediates the vasoconstrictor and growth-promoting effects of Ang II. The A1166C polymorphism of the AT1 receptor gene may be associated with cardiovascular phenotypes, such as high arterial blood pressure, aortic stiffness, and increas...

The metabolic syndrome is related to increased risk of developing cardiovascular disease and type 2 diabetes. Adiponectin is an adipocyte-secreted protein with insulin-sensitizing and anti-atherogenic properties. The aims of this study were to evaluate adiponectin levels and biochemical parameters in metabolic-syndrome subjects and healthy controls. The study also sought to identify links betwe...

Some mechanisms have been proposed to explain the role of bradykinin on glucose homeostasis and some studies reported that the BDKRB2 +9/-9 polymorphism was associated to the transcriptional activity of the receptor. In this scenario, the main aim of this study was to evaluate the association of the BDKRB2 +9/-9 polymorphism with diabetes mellitus risk in the Brazilian general population. This ...

The greatest impact of the Human Genome Project on clinical medicine is the appreciation of the extra-ordinary molecular and biochemical individuality of each patient. Gene polymorphism occurs in 1 in 1000 DNA base pairs in the human genome. This is reflected in the diversity of the gene products structural proteins, enzymes, channel proteins, transporters and binding proteins, receptors and po...
