Eleven nucleotide variations were detected: six in SLC6A8 and five in GAMT. These changes were analyzed at the mRNA level and specific alleles (most of which bore premature stop codons) were selected as nulls because they provoked nonsense-mediated decay activation. The impact of these CDS mutations on metabolic stress (ROS production, p38MAPK activation, aberrant proliferation and apoptosis) was analyzed in patient fibroblast cultures. Oxidative stress contributed toward the severe form of CDS, with increases seen in the intracellular ROS content and the percentage of apoptotic cells. An altered cell cycle was also seen in a number of CRTR and GAMT fibroblast cell lines (mostly those carrying null alleles). p38MAPK activation only correlated with oxidative stress in the CRTR cells. Based on intracellular creatine levels, the contribution of energy depletion toward metabolic stress was demonstrable only in selected CRTR cells. Together, these findings suggest that the apoptotic response to genotoxic damage in the present CDS cells may have been triggered by different cell signaling pathways. They also suggest that reducing oxidative stress could be helpful in treating CDS. Hum Mutat 32:1-10, 2011. © 2011 Wiley-Liss, Inc."xsd:string |
