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.
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.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double-Blind, Primary Purpose: Treatment

BACKGROUND: Recent evidences showed that the phytoestrogen genistein positively affects bone metabolism with no clinically significant adverse effects in a cohort of osteopenic, postmenopa...
The purpose of this study is to determine whether the phytoestrogen genistein is effective in improving bone condition in pre-menopausal and post-menopausal women suffering for osteopenia....
RATIONALE: Genistein may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving genistein before surgery may ...
This Phase I/IIa study will test the combination of the epigenetic drug decitabine with the isoflavone genistein in children with leukemias and solid tumors. For the phase I study, the ma...
RATIONALE: Drugs used in chemotherapy, such as gemcitabine hydrochloride and genistein, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping...
The age at natural menopause has subsequent health implications. Earlier age at natural menopause is a risk factor for cardiovascular disease, atherosclerosis, and stroke. Despite extensive study, no ...
Genistein is a phytoestrogen found in soy. We previously found that adult exposure to dietary levels of genistein affected gestation time, parturition time, litter size, pup weight, and pup mortality ...
Genistein, a phytoestrogen with similarities to female sex hormones, has been shown to protect against oxidative stress and fibrosis in nonalcoholic fatty liver injury in animal studies. However, few ...
Parkinson's disease (PD) is the second-most common neurodegenerative disorder and is characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta. Oxidative stress h...
The effects of genistein on angiogenesis remain poorly understood. Some studies claim an antiangiogenic effect and others claim a pro-angiogenic one. Thus, the aim of this study was to determine if ge...
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.
