New breast cancer research from Medical University of South Carolina described
December 18th, 2008
According to a study from the United States, "Prostate-derived Ets factor (PDEF) is an ETS transcription factor expressed in normal tissues with high epithelial cell content and noninvasive breast cancer cells. A putative tumor suppressor PDEF protein expression is often lost during progression to a more invasive phenotype." "Interestingly, PDEF mRNA has been found to be retained or even overexpressed in the absence of protein; however, the mechanisms for this remain to be elucidated. This study identifies two microRNAs (miRNA) that directly act on and repress PDEF mRNA translation, leading to the loss of PDEF protein expression and the gain of phenotypes associated...
