Article Title: Thrombospondin-1 triggers calreticulin expression in human mucoepidermoid carcinoma MC-3 cells via the PERK/CHOP pathway

doi: 10.3892/ol.2026.15589

Figure Lengend Snippet: TSP-1 promotes the translocation of CRT to the cell surface in MC-3 cells. Cells were stained with an APC-conjugated anti-CRT antibody, and CRT expression on the cell membrane is presented as mean fluorescence intensity. At the 72 h point: **P<0.01 vs. the control group; # P<0.05 vs. the TSP-1 group; and ▲ P<0.05 vs. the TSP-1 + ISRIB group. MFI, mean fluorescence intensity; CRT, calreticulin; TSP-1, thrombospondin-1.

Article Snippet: Primary antibodies, including anti-PERK (1:1,000; cat. no. MA8131; Abmart Pharmaceutical Technology Co., Ltd.), anti-CHOP (1:1,000; cat. no.
