Western blot analysis showing that expression of HPV16E6 in HT3 cells increased the protein level of total YAP and casein kinase Iε, but decreased the protein level of SOCS6. Importantly, HPV16E6 increased YAP phosphorylation at serine 127, but suppressed its phosphorylation at serine 397. HPV16E6 had no effect on the level of β-TrcP, LATS1/2 and MOB1 in HT3cervical cancer cells.
