Grape seed extract is an aromatase inhibitor and a suppressor of aromatase expression.

Aromatase is the enzyme that converts androgen to estrogen. It is expressed at higher levels in breast cancer tissues than normal breast tissues. Grape seed extract (GSE) contains high levels of procyanidin dimers that have been shown in our laboratory to be potent inhibitors of aromatase. In this study, GSE was found to inhibit aromatase activity in a dose-dependent manner and reduce androgen-...

Aromatase over expression transgenic murine models for aromatase inhibitor studies.

In recent years the emerging importance of estrogen signaling in males in addition to its major role in the female reproductive system became highlighted. Aromatase is the key enzyme for synthesis of estrogens from androgens and is responsible for controlling the androgen/estrogen ratio. Inhibition of aromatase gene expression can be achieved in different ways and is important for the treatment...

The HDAC inhibitor LBH589 (panobinostat) is an inhibitory modulator of aromatase gene expression.

Aromatase converts androgens to estrogens. Although third-generation aromatase inhibitors (AIs) are important drugs in hormonal therapy for breast cancer in postmenopausal women, there are concerns about the side effects associated with the estrogen deprivation achieved with AIs. Expression of aromatase in breast cancer tissue is driven by different promoters than those in noncancer tissues; th...

Appraising adjuvant aromatase inhibitor therapy.

Tamoxifen, once the gold standard adjuvant endocrine therapy for early breast cancer, is being challenged by third-generation aromatase inhibitors (AIs) that have demonstrated improved disease-free survival in a variety of adjuvant settings for early breast cancer. Tamoxifen and AIs have different safety profiles, which should allow physicians to begin to individualize treatment based on a pati...

In one study, 287 patients diagnosed with asymptomatic carotid plaques or abnormal plaque free carotid intima-media thickness (CIMT) were randomly assigned to a GSE group (n = 146) or control group (n = 141). As anticipated, after treatment, GSE resulted in significant reduction in MMCIMT progression, while MMCIMT and plaque score were stable and even increased with the control group. The numbe...
