The paradox of hnRNPK: both absence and excess impair skeletal muscle function in mice.

ABSTRACT:

Background

The RNA-binding protein hnRNPK is essential for animal growth and development, with a particular emphasis in myogenesis. Despite its importance, the precise mechanisms by which hnRNPK influences skeletal muscle physiology and development remain inadequately characterized.

Methods

To explore its regulatory function, we developed a Myf5-cre-mediated myoblast precursor-specific knockout mouse model (Hnrnpk mKO), an Acta1-CreEsr1-mediated myofiber-specific inducible knockout mouse model (Hnrnpk aKO), and an AAV9-mediated skeletal muscle-specific overexpression mouse model (AAV9-hnRNPK). Morphological alterations in skeletal muscle were assessed using hematoxylin and eosin (HE) staining subsequent to hnRNPK knockout or overexpression. Global gene expression changes in
