background: the metabolically active tumor cells may be characterized by a pronounced adenosine release that regulates the growth and development of the tumor. consequently, the expression pattern of defined receptor subtypes will be an important determinant for specific effects of adenosine on the control of tumor cell growth. in recent studies, the expression profile, signal transduction, mol...

Phytoestrogens have become one of the more topical areas of interest in clinical nutrition. These non-nutrient bioactive compounds are ubiquitous to the plant kingdom and possess a wide range of biological properties that contribute to the many different health-related benefits reported for soy foods and flaxseeds--two of the most abundant dietary sources of phytoestrogens. Reviewed is the rece...

It has been shown that higher levels of estrogens in females protect them against aging by upregulating the expression of antioxidant longevity-related genes. Phytoestrogens are naturally occurring polycyclic phenols found in certain plants that have weak estrogenic effects due to the fact that they are structurally and functionally similar to 17ß-estradiol, and thus, bind to estradiol receptor...

Regulation of linear bone growth in children and adolescents comprises a complex interaction of hormones and growth factors. Growth hormone (GH) is considered to be the key hormone regulator of linear growth in childhood. The pubertal increase in growth velocity associated with GH has traditionally been attributed to testicular androgen secretion in boys, and to oestrogens or adrenal androgen s...

BACKGROUND This study investigates the effect of alendronate-treated osteoblasts, as well as the effect of low-level laser therapy (LLLT) on the alendronate-treated osteoblasts. Bisphosphonate decreases the osteoblastic activity. Various treatment modalities are used to enhance the bisphosphonate-treated osteoblasts; however, there were no cell culture studies conducted using a low-level laser....

background: type-i diabetes is an autoimmune inflammatory disease in which pancreatic ß-cells are selectively destroyed by infiltrating cells. tnf-related apoptosis-inducing ligand (trail) is a type-ii membrane protein of the tnf superfamily which is expressed in different tissues, including pancreas and lymphocytes. in humans, trail interacts with four membrane receptors. trail-r1 and trail-r2...

Phytoestrogens are a diverse group of plant-derived compounds that structurally or functionally mimic mammalian estrogens and show potential benefits for human health. The number of articles published on phytoestrogens has risen dramatically in the past couple decades. Further research continues to demonstrate the biological complexity of phytoestrogens, which belong to several different chemic...

Oestrogens, including the natural hormones oestrone and oestradiol, induce various tumours in laboratory animals and have been recognized to be carcinogens in humans, raising the risk for breast and uterine cancer. As part of the search for the mechanism of hormone-induced carcinogenesis, various types of DNA damage have been detected which have been induced by oestrogens in cell-free systems, ...
