 (F) CHO inducible cells expressing either wildtype M or Z α1-antitrypsin were induced with 0.5μg/mL doxycycline and treated with 10μM GSK716 or with 0.1% DMSO vehicle (NT, not treated). After induction for 48 h, cells were treated with various doses of tunicamycin for 36 h. Cell viability was measured by Cell Counting Kit-8. The results are shown as mean±SEM, n=4
