Statin-induced transcriptional changes in breast cancer


ABSTRACT: Global gene expression profiling was performed on paired tumor biopsies collected before and after 2 weeks of statin treatment with the aim of detecting statin induced changes on tumoral gene expression. In this phase II clinical study using the “window-of-opportunity” design, in which the treatment-free window between a cancer diagnosis and surgical tumor resection is used to study the biological effects of a certain drug, atorvastatin, a lipophilic statin, was prescribed to patients with primary breast cancer for two weeks pre-operatively. Tumor samples subjected to whole genome transcriptional profiling were collected before patients started treatment and after completing treatment.

Statins purportedly exert antitumoral effects, but the underlying mechanisms are currently not fully elucidated. The aim of this study was to explore potential statin-induced effects on global gene expression profiles in primary breast cancer.This window-of-opportunity phase II trial enrolled 50 newly diagnosed breast cancer patients prescribed atorvastatin (80 mg/day) for 2 weeks presurgically. Pre- and posttreatment tumor samples were analyzed using Significance Analysis of Microarrays (SAM) t  ...[more]
