Further, cargoes of XPO1 also include the oncoprotein mRNAs cellular myelocytomatosis (c‐MYC), cyclin D1 and murine double minute 2 (MDM2), and their transport to the cytoplasm thus promotes the synthesis of these oncoproteins, which are known to be upregulated in MM [29]. This evidence concerns the gene XPO1 and Miyoshi myopathy.
