HNRNPA1 and infection: To investigate the in vivo implication of hnRNPA1 in arterial remodeling, we first generated Lenti-GFP (green fluorescent protein; control) and Lenti-hnRNPA1 lentiviral particles and observed high infection efficiency (>80% of cells were positive for GFP) in primary mouse VSMCs (Figure VIIIA in the online-only Data Supplement).
