MYH9 and infection: The results indicated that all these cells except HeLa-MYH-9 had nearly the same levels of myosin-9 (Fig. 6B), but the infection of HPV16 in CHOK1 cells was significantly lower than those in the other three cells (Fig. 6C), suggesting that the N-glycans on CHOK1 cells could interfere with HPV infection without influencing the expression of myosin-9.
