CCND1 and breast cancer: There is a consistently demonstrated occurrence between co-amplification of genomic loci harboring 4EBP1 (EIF4EBP1) and Cyclin D1 (CCND1) in breast cancer patients such as the recent report by Giltnane and colleagues [27], so further studies should assess how these two oncogenes together can influence cell cycle states, meiotic progression, and the regulation of aneuploidy.
