The expression level of luciferase within tumour cells can alter tumour growth upon in vivo bioluminescence imagingSusan Brutkiewicz
Department of Obstetrics and Gynecology, Indiana University School of Medicine, Indianapolis, IN 46202, USA
Luminescence 22:221-8. 2007..The observation that a high level of luciferase expression will inhibit tumour cell growth when an animal is subjected to serial in vivo bioluminescence imaging is potentially an important factor in designing these types of studies...
Estrogen promotes tumor progression in a genetically defined mouse model of lung adenocarcinomaZane Hammoud
Department of Obstetrics and Gynecology, Indiana University School of Medicine, 975 West Walnut Street IB360, Indianapolis, Indiana 46202 5121, USA
Endocr Relat Cancer 15:475-83. 2008..In conclusion, estrogen acts as a promoter for lung adenocarcinoma in a genetically defined lung cancer model; estrogen-induced cell proliferation in the oncogene-initiated cells is likely to play a role in this tumor promoter activity...

Technol Cancer Res Treat 2:449-54. 2003..Our results validate the use of the Gamma Knife for cataract studies in rodents, and confirmed the precision and utility of the instrument as a small animal irradiator for translational radiobiology experiments...
The activating enzyme of NEDD8 inhibits steroid receptor functionMeiyun Fan
