TMEM16A is important for cellular survival in HPV-negative, but not HPV-positive cell lines.
(a–d) Cell survival study with varying concentrations of the small molecule inhibitor of TMEM16A, CaCCinh: The two HPV-positive cell lines, (a) 93-VU-147T and (b) SCC90, had much higher IC50s for CaCCInh than the HPV-negative cell lines, (c) FaDu and (d) PE/CA-PJ34. (e) Table comparing the IC50s of each cell line.
