Four of them (HMX2, HNF4A, LEF1, MAFB) are known to be expressed in the islets of Langerhans, and MAFB is known to be expressed only in rodent islet α cells within adult pancreas [25]; the presence of binding sites for this TF within the promoter of the genes encoding miR-296-3p and miR-298-5p suggests that it may regulate the expression of both miRNAs.

Altogether, high-throughput microRNA profiling, functional analysis with synthetic mimics and molecular characterization of modulated pathways strongly suggest that specific downregulation of miR-296-3p and miR-298-5p, coupled to upregulation of their targets as IGF1Rβ and TNFα, is a major determinant of mammalian pancreatic α cells resistance to apoptosis induction by cytokines.

In vivo, we observed decreased expression levels of miR-298 and miR-328 in the hippocampus of aging APPSwe/PS1 mice [8], which supports further the possibility that the loss of miRNA regulation of BACE1 mRNA translation may lead to higher BACE1 protein expression, an enhanced Aß formation and the development of AD.

Mir-136 and mir-718 were not detectable in the adipocyte cultures using the Taqman assays-on-demand, while mir-346, mir-298, mir-330 and mir-501 were expressed at low levels (Ct levels above 33), see Table 1. This suggests that currently there is no gold standard method (when RNA is limiting) to validate miRNA data profiles.
