Downstream of Bid (DOBI) known as Pus10, has been identified as a modulator of TRAIL-induced cell death using RNAi library screening. The crystal structure of DOBI has revealed that it is a crescent-shaped protein containing the pseudouridine synthase catalytic domain and a THUMP-containing domain. Here, we demonstrated that DOBI is expressed in various tissues such as heart and lung, and is also expressed in various tumor cells such as HeLa and A549. Although ectopic expression of DOBI does not promote TRAIL death signaling in HeLa cells, knock-down of DOBI expression using shRNA inhibited TRAIL death signaling. DOBI is cleaved into a 54 kD cleaved DOBI during cell death, and the recombinant DOBI protein can be directly cleaved by caspases-3, or -8 in vitro. Together, these data suggest that the cleaved DOBI may acquire a new function, possibly by cooperating with tBid in the mitochondrial event of cell death caused by TRAIL.

This article examined the different types of Jeonuhwa as recorded in 16 royal palace studies from the Joseon dynasty (1392-1909). The ingredients used in Jeonuhwa during the Joseon dynasty were categorized as follows: 16.0% for gray mullet(秀魚) and fish(生鮮), 14.2% each for liver and cow stomach, 12.3% for sea cucumber(海蔘), 4.7% each for crab(蟹), clam(生蛤), and chunyup(千葉), 3.9% each for pork meat(豬肉), octopus, 2.8% each for oyster(石花), pheasant(生雉), and chicken(鷄), 2.0% each for croaker(民魚), and brain (骨), 0.9% each for duck(鴨子), pigeon(山鳩), dobi(都飛), snapper, white fish(白魚), mussel(紅蛤), haeran(蟹卵), quail(鶉鳥), egg(鷄卵), and sesame(實荏子). This observation may be associated with commercial industrial development that prevailed during the late Joseon dynasty. Further studies will be conducted on recipes and ingredients recorded in Euigwe in order to develop a standardized recipe for Jeonuhwa.
