The aromatase inhibitor letrozole restores FADS2 function in ER+ MCF7 human breast cancer cells ✰

DNA amplification is a common mechanism leading to oncogenic activation in cancers [1 –3]. Several oncogenes map to the human chromosome 11q13 (HSA 11q13), established as among the most frequently amplified genomic regions in a number of human cancers, including breast cancer (BC) [2, 4–8]. The 11q13 region is amplified in 15–20% of BC and comprises multiple amplicons highly va riable in size, spanning several Mb of DNA from 11q12.2 to 11q14.1 [9–14]. 11q13 amplification in BC is associated with estrogen receptor (ER) expression, resistance to hormone therapy and poor prognosis [5, 14–17].
