"Data suggest that endoplasmic reticulum (ER) stress-induced apoptosis in hepatoma cells is regulated by highly labile and ER-associated BCL-2 family member BOK which is controlled at level of protein stability by ER-associated degradation components; DNAJB12 is required in hepatoma cells to maintain BOK at low levels and suppress ER stress. (DNAJB12 = DnaJ (Hsp40) homolog subfamily B member 12)"xsd:string
