RESEARCH HIGHLIGHTS Members of the Division have been reasonably successful in establishing research collaborations with the Division of Radiation Oncology. Three themes are extremely active at the moment.

Faslodex alcohol Are less efficacious at inhibiting the aromatase enzyme. This is reflected in the fact that compared with the transplanted tumors treated with letrozole, E2 concentrations in the tumors treated with anastrozole and formestane are 1.5-fold and 2.5-fold higher, respectively. Although serum E2 levels were lower in the animals treated with anastrozole and formestane compared with the animals treated with letrozole, our results suggest that tissue E2 concentrations may be more important, because this is a reflection of the amount of E2 available in the tumor microenvironment. The half-life of anastrozole in rodents has been reported to be considerably shorter than the half-life of letrozole 47 ; . Therefore, the circulating levels of anastrozole may not approach those of letrozole. Thus, anastrozole may not be completely inhibiting tumor aromatase activity and, as a consequence, tumor growth. However, it is important to note that in our previous studies 30, 31 ; we reported that anastrozole had potent antitumor activity at a daily dose of 10 g day, and in this study anastrozole was administered at ten times that dose. After transplantation of the long-term letrozole-treated tumors, letrozole slowed but did not regress tumor growth, and tumor volumes actually increased slowly over the duration of the experiment. Thus, the transplanted tumors appear to have acquired at least partial but not complete resistance to letrozole. This suggests that there is a possibility of returning to letrozole therapy after initial relapse and second-line therapy with an antiestrogen. Nonetheless, in these experiments the transplanted long-term letrozole-treated tumors retained sensitivity to secondline treatment with the antiestrogens tamoxifen and faslodex. The pure antiestrogen faslodex was very effective at slowing tumor growth. In fact, over the 8-week duration of the experiment the volumes of the tumors treated with faslodex increased by only 0.55-fold. In summary, we have used the aromatase-transfected, estrogendependent MCF-7Ca human breast cancer cell line, and shown that when cells and tumor xenografts acquire the ability to proliferate in an estrogen-depleted environment in vitro they remain sensitive to second-line therapy with tamoxifen. Moreover, after a long-term treatment with the aromatase inhibitor letrozole in vivo, transplanted MCF-7Ca tumor xenografts are sensitive in the second-line to tamoxifen and to a greater extent to faslodex. This is most likely because of the increased cellular ER levels that enhance the sensitivity of estrogen-deprived cells to the antiproliferative effects of antiestrogens and felbamate.

Kimata, Institute for Molecular Science of Medicine, Aichi Medical University, for continuous encouragement and helpful suggestions throughout this study. In addition, estradiol administration significantly reduced the incidence and duration of reperfusion-induced ventricular tachycardia and ventricular fibrillation. Although 5-hydroxydecanoate alone caused no significant effect on the incidence of reperfusion arrhythmias in the presence or absence of estradiol, the administration of HMR 1098 abolished estrogen-induced improvement of reperfusion arrhythmias. Pretreatment with the estrogen-receptor antagonist faslodex ICI 182, 780 ; did not alter estrogen-induced infarct-limiting and antiarrhythmic effects. These results demonstrate that estrogen is cardioprotective against infarct sizes and fatal reperfusion arrhythmias by different ATP-sensitive K channels for an estrogen receptor-independent mechanism. The infarct size-limiting and antiarrhythmic effects of estrogen were abolished by 5-hydroxydecanoate and HMR 1098, suggesting that the effects may result from activation of the mitochondrial and sarcolemmal ATP-sensitive K channels, respectively and fennel.

It is very important that there is someone like Dr. Stone who is working to develop these new techniques of biologic joint reconstruction and willing to push the envelope to benefit the growing number of people like me who want to stay active and avoid prosthetic joint replacement. I feel very fortunate to have found him. Dan Cohen.

Sanke, a neuro-ophthalmologist from Minot, ND, arrived From left: David Epstein, MD and at the Eye Center in OctoRobert Sanke, MD, FACS ber as a visiting observer to learn about the latest methods of glaucoma treatment. With his specialty training, he had done much work with the optic nerve and had a special interest in learning more about glaucoma. During his visit Sanke accompanied faculty members as they saw patients and performed surgery, and he attended education programs such as grand rounds and research seminars. He says he was impressed by the Eye Center's high-quality advanced research and its use of newer diagnostic techniques. In Minot Sanke sees patients at the Williams Clinic at Trinity Medical Center.
