βE2 treatment prevented the PCSK9-induced recruitment of clathrin. (A) HepG2 cells were incubated in the presence of rhPCSK9 (25 μg/mL), and clathrin levels were measured the specified time intervals. (B) HepG2 cells were treated with βE2 (0.01–1 μM) for 2 h in the presence of rhPCSK9 and were visualized for the detection of immunofluorescence-stained clathrin. The fluorescent quantification of clathrin was determined by ZEISS 2010 software. Values represent the means ± SEM, n = 3; *P < 0.05 for a comparison between two groups.
