2.4.1.87 | medicine | development of alpha-1,3-galactosyltransferase (GGTA1) and cytidine monophosphate-N-acetylneuraminic acid hydroxylase (CMAH) double-knockout piglets as donor animals for xenotransplantation. Compared to cells from GGTA1-knockout pigs, human antibody binding and antibody-mediated complement-dependent cytotoxicity are significantly reduced in cells from GGTA1/CMAH double-knockout pigs | Sus scrofa |

1.14.18.2 | additional information | production of alpha1,3-galactosyltransferase and cytidine monophosphate-N-acetylneuraminic acid hydroxylase gene double-deficient pigs by CRISPR/Cas9 and cloning in porcine fetal fibroblast cells. Generation of bi-allelic GGTA1 and CMAH double-knockout cells, GGTA1/CMAH double-knockout (DKO) cells are cloned to produce piglets. Compared to cells from GGTA1-knockout pigs, human antibody binding and antibody-mediated complement-dependent cytotoxicity are significantly reduced in cells from GGTA1/CMAH DKO pigs, demonstrating that the pigs might exhibit reduced humoral rejection in xenotransplantation | Sus scrofa |

1.14.18.2 | physiological function | enzyme CMP-N-acetylneuraminic acid hydroxylase (CMAH) is responsible for the synthesis of N-glycolylneuraminic acid (Neu5Gc), a sialic acid present on the cell surface proteins of most deuterostomes. CMAH is the only enzyme capable of synthetizing Neu5Gc | Sus scrofa |
