Vascular and Skeletal Protective Effects of Genistein in Postmenopausal Women

2014-07-24 14:24:18 | BioPortfolio

Summary

The present research program is proposed deepening some pharmacological effects of the genistein therapy in order to individualize alternative treatments to the conventional hormonal replacement therapy useful to reduce the cardiovascular morbidity and mortality and the osteoporotic consequences in postmenopausal women.

Description

Genistein is a phytoestrogen of the isoflavone family which has been shown to have beneficial effects on endothelial function and bone metabolism. On the basis of the so far obtained results, aim of our research was to investigate for a two years period the effects of genistein on cardiovascular risk factors, endothelial function and oxidative stress markers, bone metabolism and finally clarify pathophysiology mechanisms (by dosage of cytokines and endothelial markers) by which this molecule could interfere on atherosclerosis and bone mass loss progression.

Particularly, and in extreme synthesis the following parameters have been studied during the treatment:

1. inflammation markers as fibrinogen

2. lipid profile - total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, lipoprotein(a)-

3. endothelial function markers as VCAM-1 and ICAM-1

4. oxidative stress by the evaluation of the F(2)-isoprostane

5. cytokines as IL-6, OPG, RANK and RANKL

6. bone mineral density, by DEXA, at lumbar spine and femoral neck

7. Bone turnover markers as B-ALP, PYR, D-PYR

8. PAP-test, transvaginal uterine ecography and mammography.

Medical and Biotech [MESH] Definitions

The transitional period before and after MENOPAUSE. Perimenopausal symptoms are associated with irregular MENSTRUAL CYCLE and widely fluctuated hormone levels. They may appear 6 years before menopause and subside 2 to 5 years after menopause.

Metabolic disorder associated with fractures of the femoral neck, vertebrae, and distal forearm. It occurs commonly in women within 15-20 years after menopause, and is caused by factors associated with menopause including estrogen deficiency.

The last menstrual period. Permanent cessation of menses (MENSTRUATION) is usually defined after 6 to 12 months of AMENORRHEA in a woman over 45 years of age. In the United States, menopause generally occurs in women between 48 and 55 years of age.

The premature cessation of menses (MENSTRUATION) when the last menstrual period occurs in a woman under the age of 40. It is due to the depletion of OVARIAN FOLLICLES. Premature MENOPAUSE can be caused by diseases; OVARIECTOMY; RADIATION; chemicals; and chromosomal abnormalities.

The physiological period following the MENOPAUSE, the permanent cessation of the menstrual life.
