Propofol inhibits ER stress-associated proteins induced by TG with immunofluorescence assay.

(A-F) A series of representative images of PERK, p-PERK, eIF2α, p-eIF2α, ATF4 and NF-κB from immunofluorescence assay in three groups are shown. ARPE-19 cells were pretreated with 40 μM propofol for 12 h and then exposed to 1μM TG for 12 h. Nuclei were labeled with DAPI (blue).
