Researchers at Yale School of Medicine have discovered the breast cancer growth regulator sEGFR, which may be a useful tool in monitoring a patients responsiveness to treatment with the drug letrozole.
Published in a recent issue of the American Association of Cancer Researchers journal Cancer Research, the study focused on how decreased concentrations of sEGFR can indicate the effectiveness of letrozole.
In women with postmenopausal breast cancer, the hormone estrogen often stimulates tumor growth. Letrozole, which is currently used in breast cancer therapy, stops the local production of estrogen, therefore reducing tumor growth. To monitor the effectiveness of this drugs reduction in tumor growth, estrogen levels are measured. In postmenopausal women with breast cancer, estrogen can be difficult to measure because the levels are already quite low. The Yale team, led by Nita J. Maihle, professor in the Department of Obstetrics, Gynecology & Reproductive Sciences, discovered sEGFR, another regulator of breast cancer growth that can be used to measure responsiveness to treatment.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
