2. Application
17alpha-methyl testosterone is used widely as a component of hormone replacement therapy. Previous reports have indicated that contrary to , 17alpha-methyl testosterone is not aromatized. However, 17alpha-methyl testosterone still could affect local estrogen formation by regulating aromatase expression or by inhibiting aromatase action.
Both possibilities have important clinical implications. To evaluate the effect of 17alpha-methyl testosterone on the expression and activity of aromatase, we tested the choriocarcinoma Jar cell line, a cell line that express high levels of P450 aromatase, and the macrophage-like THP-1 cells, which express aromatase only after undergoing differentiation. We found that in both cell lines, 17alpha-methyl testosterone inhibits aromatase activity in a dose-related manner.
The curve of inhibition parallels that of letrozole and gives complete inhibition at 10(-4) M 17alpha-methyl testosterone, determined by the tritium release assay. 17alpha-methyl testosterone does not have detectable effects on aromatase RNA and protein expression by Jar cells.
Undifferentiated THP-1 cells had no aromatase activity and showed no effect of 17alpha-methyl testosterone, but differentiated THP-1 (macrophage-like) cells had a similar inhibition of aromatase activity by 17alpha-methyl testosterone to that seen in Jar cells. The Lineweaver-Burke plot shows 17alpha-methyl testosterone to be a competitive aromatase inhibitor.
Our results show for the first time that 17alpha-methyl testosterone acts as an aromatase inhibitor. These findings are relevant for understanding the effects of 17alpha-methyl testosterone as a component of hormone replacement therapy. 17alpha-methyl testosterone may, as a functional androgen and orally active steroidal inhibitor of endogenous estrogen production, also offer special possibilities for the prevention/treatment of hormone-sensitive cancers.
3. How to use
17-Methyltestosterone, Take this medication by mouth with or without food,usually 1 to 4 times a day, as directed by your doctor. Dosage is based on your medical condition, testosterone blood levels, and response to treatment.
17-Methyltestosterone, Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same times each day.
17-Methyltestosterone, Do not suddenly stop using methyltestosterone if you have been using it regularly for an extended time or if it has been used in high doses. In such cases,your body will no longer make its own testosterone, and withdrawal reactions (such as tiredness,weakness,depression) may occur. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details,and report any withdrawal reactions immediately.
17-Methyltestosterone,Abnormal drug-seeking behavior is possible with this medication, and it is frequently misused for its muscle-enhancing effects. Do not increase your dose, take it more frequently, or take it for a longer time than prescribed. Doing so may increase serious side effects (such as increased risk for heart disease,stroke, liver disease, ruptured tendons/ligaments, improper bone development in adolescents). Properly stop the medication when so directed
