And brother i am not cured, I am recovering, I am expecting this step backs. I wish that in the end my worst case scenario is to keep my libido with sensitivity and best case is to complete reversal of pfs I believe it is possible. May be this increase on Ed is like the situation after we quit finasteride body overwhelmed with dht and free testosterone…

The binding of androgens to the AR increases the stability of the protein, transiently elevating AR protein levels in a variety of cell types22. The expression of the AR in MCF-7 cells usually is rather modest as can be seen in Fig. 3a, b. It can be enhanced considerably by incubation with DHT for 3 days. Surprisingly Exemestane is considerably more effective than Formestane. The western blot results are complemented by immunofluorescence results showing a drastic increase of the AR expression in MCF-7 cells caused by the incubation with the AIs and their derivatives. Immunofluorescence results also show a translocation of liganded AR into the nucleus. In contrast to the control, most AR proteins locate in treated cells nucleus (Fig. 3c). Apparently the induction of the AR is an additional feature of these substances which are able to inhibit the proliferation of ER(+)/AR(+) breast cancer cells through activating AR as androgens.
To confirm that steroidal AIs and their 17-OH derivatives reduce the growth of ER(+) breast cancer cells by activating AR, we investigate whether these compounds can bind to AR protein and promote AR transcriptional activity. As shown in Fig. 4a, 17-OH derivatives of Exemestane and Formestane competitively bind AR with an IC50 of 10.44 and 18.16 nM, respectively. Their affinity to the AR is almost as high as that of DHT (IC50, 4.02 nM).
