Analysis of Numb 3’ UTR in Mouse Skeletal Muscle

Description
The Numb gene encodes an adaptor protein that has been shown to play a role in muscle repair, cell proliferation, and the determination of cell fate in satellite cells. Ablation of this gene in satellite cells results in an up-regulation of myostatin and p21, which inhibit the proliferation of myoblasts.…

The Numb gene encodes an adaptor protein that has been shown to play a role in muscle repair, cell proliferation, and the determination of cell fate in satellite cells. Ablation of this gene in satellite cells results in an up-regulation of myostatin and p21, which inhibit the proliferation of myoblasts. These results indicate that the regulation of numb and myostatin could be used to amplify muscle regeneration. This would function as a therapeutic approach to degenerative muscle diseases, such as muscular dystrophy. There are four mammalian NUMB proteins produced through alternative splicing of the Numb mRNA transcript. Only two isoforms are present in adult mammalian muscle, indicating some form of muscle-specific post-transcriptional control of the gene. Additionally, the presence of two polyadenylation sites, and multiple miRNA seed sequences within the 3’ untranslated region (UTR) of mouse Numb indicate the possibility of regulation by a muscle specific miRNA.
