Lamin A/C regulates cerebellar granule cell maturation.

ABSTRACT: Lamin A/C is a nuclear type V intermediate filament protein part of the meshwork structure underlying the inner nuclear membrane (nuclear lamina), which plays numerous roles, including maintenance of nuclear shape, heterochromatin organization, and transcriptional regulation. Our group has demonstrated the role of Lamin A/C in different pathophysiological conditions. Here, we investigated for the first time how Lamin A/C affects neuronal maturation in rat cerebellar granule cells (GCs). Primary rat cerebellar GCs where we silenced the Lmna gene constituted our key model; this provided a rather homogeneous cellular system showing a neuronal population in vitro. We then validated our findings in another in vivo murine model with knock-out of the Lmna gene and in an in vitro human neuronal mo
