Abstract
|
|
|
|
Due to the shortage of human organ donors for transplant, various studies of xenotransplantation, or the use of animal organs instead of human organs, have been carried out. The organs of porcine are thought to be safer and of a more suitable size for xenotransplantationthan those of nonhuman primates. Understanding the levels of expression of proteins, and their post-translational regulation, would be very practical between different species and among developing stages, though the molecular profiling for xenotransplantation has been rarely studied for porcine, while that of human and rodent is well known. Here, in this present study, we report protein regulation of the developing stages of liver (4-day old neonate, 19-day old piglet and 14-month old adult miniature pigs) using 2-DE and MALDI-TOF. From images of the three different stages, a total of 8 spotswhich were differently regulated were identified, and 5 spots were identified with MALDI-TOF MS. The data presented within this study provides critical direction relating to the development of livers of miniature pigs, which will assist future proteome analysis of the liver, and advance our understanding of the hurdles facing xenotransplantaion.
