A: n = 11 human head and neck squamous cell carcinoma (HNSCC) samples were assessed for TMEM16A, cl-PARP, pErk 1/2, and Bim expression by western blot. B: TMEM16A expression had a strong, positive correlation with tumor size and a modest, negative correlation with cl-PARP in human HNSCC samples. C: TMEM16A expression had a strong, positive correlation with pErk 1/2 expression and a strong, negative correlation with Bim. p < .05 denotes a significantly non-zero slope of the trend line. Blots cropped for conciseness; clinical demographic information and full length blots available in supplemental materials.
