Transcription levels of apoptosis-associated genes. Choriocarcinoma JEG-3 cells were transfected with either the empty vector (pEGFP, encoding enhanced green fluorescent protein) or pEGFP-GRA15II for 24 h. Abbreviations: ATF, activating transcription factor; GRP78, 78-kDa glucose-regulated protein; CHOP, C/EBP homologous protein; XBP1, X-box binding protein-1. *P < 0.05, **P < 0.01, when compared to the pEGFP-transfected cells
