PAK6 and neuroblastoma: To investigate the involvement of PAK6 in ciliogenesis in brain cells, we generated polyclonal stable neuroblastoma SH-SY5Y cells overexpressing PAK6 via lentiviral vector (PAK6 OE) and, as control, downregulated PAK6-OE cells with LV-shRNA against PAK6 (PAK6 OE + PAK6 shRNA) (Fig. 3b).
