NORAD and breast cancer: NORAD is highly conserved, it maintains genomic stability by repressing the stability and translation of mRNAs sequestering the PUMILIO protein.10 Previously, we reported that NORAD can act as a promoter of cellular stress responses in melanocytes.11 Moreover, NORAD knockdown suppresses the growth and proliferation of breast cancer cells, suggesting that NORAD may play an oncogenic role in breast cancer.12 However, the functions of NORAD in MM are still unknown.
