Trehalose relieves oxidative stress induced ER stress in chondrocytes. (a and b) The protein levels of GRP78, CHOP, Caspase 12 and Caspase 9 in chondrocytes were detected. (c and d) Double immunofluorescence staining of p62 and CHOP in chondrocytes. (Green: p62, red: CHOP, bar: 10 μm). All data represent mean±S.D. (n=5). **P<0.01, *P<0.05
