Figure 6. Immunofluorescent evaluation of (A) PER2 protein expression in PLC/PRF/5 parental, PLC/PRF/5 EveR, and PLC/PRF/5 SorR, and (B) colocalization of PER2 and CK1ε in PLC/PRF/5 parental, PLC/PRF/5 EveR, and PLC/PRF/5 SorR. PER2: Period 2; CK1ε: casein kinase 1ε; EveR: everolimus-resistant; SorR: sorafenib-resistant.
