In addition, menin has been reported to directly regulate the expression of miRNA genes via its role as a transcriptional regulator or through miRNA processing (Luzi et al. 2012a,b, Wang et al. 2013, Gurung et al. 2014, Li et al. 2014, Ouyang et al. 2015, Ehrlich et al. 2017, Hou et al. 2017), although the role of miRNAs in MEN1-associated tumours remains to be established. This evidence concerns the gene MEN1 and neoplasm.
