ARHGAP30 and lentivirus infection: As shown in Fig. 2, we observed significant upregulation of ARHGAP30 mRNA (Fig. 2a) and protein expression (Fig. 2c) in ASPC1 cells in response to oeARHGAP30 lentivirus infection, as well as the significant downregulation of ARHGAP30 expression in SW1990 cells infected with three shARHGAP30 lentiviruses (Fig. 2b and d).
