Aromatase Inhibitors: How much it Bites the Bone?
نویسندگان
چکیده
Tamoxifen in treatment of breast cancer is replaced by aromatase inhibitors (AI’s) which blocks and prevent estrogens by inhibiting aromatase enzyme. Treatments in breast cancer, such as oophorectomy, gonadotropin-releasing hormone (GnRH) agonists, chemotherapy and AIs, all decrease endogenous estrogens and cause significant decrease in bone mineral density (BMD) leading to bone loss and increase the risk of fractures. There is evidence to suggest that various musculoskeletal issues (pains) may be associated with low circulating estrogen levels. The most important and efficient step in preventing AI induced fracture risk is to assess for other clinical risk factors for osteoporosis before initiating AIs. The most robust non-BMD risk factors are age and prevalent fracture. The various steps in prevention of AIs induced fracture are. 1. Healthy and active lifestyle. 2. Regular Vitamin D and Calcium supplements. 3. Vigilant Monitoring of affected areas.

The comparison of the effect of different inhibitors on aromatase enzyme effective in the breast cancer by molecular docking method
Background: Aromatase is an enzyme that plays an important role in the development of estrogen-positive breast cancer. Estrogens are essential in human and mainly in women because of their role in sexual development and reproduction. Adverse effects of some aromatase inhibitors increase the need to discover new inhibitors with higher selectivity, lower toxicity and improved potency. In this stu...

In postmenopausal women, the use of aromatase inhibitors increases bone turnover and induces bone loss at sites rich in trabecular bone at an average rate of 1-3% per year leading to an increase in fracture incidence compared to that seen during tamoxifen use. The bone loss is much more marked in young women with treatment-induced ovarian suppression followed by aromatase inhibitor therapy (ave...

Change in sex ratios for broiler chickens, has many economic benefits of the poultry industry. The gonads in chick embryo at an early stage have the potential to convert to both sexes (male and female). Sexual differentiation is due to aromatase expression in the left gonad in 5-6 days of the embryonic period and the production of estrogen from testosterone. Administration of aromatase inhibito...
متن کاملAromatase and its inhibitors: significance for breast cancer therapy.
Endocrine adjuvant therapy for breast cancer in recent years has focussed primarily on the use of tamoxifen to inhibit the action of estrogen in the breast. The use of aromatase inhibitors has found much less favor due to poor efficacy and unsustainable side effects. Now, however, the situation is changing rapidly with the introduction of the so-called phase III inhibitors, which display high a...
متن کاملStatus of aromatase inhibitors in relation to other breast cancer treatment modalities.
Aromatase is one of the key enzymes possibly linked with the perpetuation or even initiation of breast cancer. Modulation of its activity by the new generation inhibitors has resulted in increased responses and improved therapeutic ratio compared with those of parent aromatase inhibitors. More recent trials have shown promising results with regard to improved therapeutic ratio compared with wha...
