PG - 2127-32 AB - The relationship between the proliferative dependent expression of the glyceraldehyde-3-phosphate dehydrogenase (GAPDH)/uracil DNA glycosylase (UDG) gene and the induction of uracil DNA glycosylase activity was examined in human cells. Three different cell types were studied to determine whether the growth-dependent regulation of this multifunctional gene was a common characteristic of human cells. These included WI-38 normal embryonic lung fibroblasts, a Japanese Bloom's syndrome non-transformed skin fibroblast cell strain (GM-05289) and a lymphoblastoid cell line transformed by the Epstein-Barr virus. The Japanese Bloom's syndrome cells displayed the altered immunoreactivity with marker monoclonal antibody 40.10.09 which characterizes cells from this human genetic disorder. In noncycling human cells Northern blot analysis using a plasmid (pChug 20.1) which contained the human GAPDH/UDG cDNA revealed a single 1.6 kb transcript. In each case, the expression of this gene was increased during cell proliferation. This increase in GAPDH/UDG gene expression was identical to that observed for UDG enzyme activity. Further, using anti-human UDG monoclonal antibodies, there was a growth-dependent rise in immunoreactivity suggesting an increase in the level of antigenic protein. These results demonstrate that: (i) the expression of the GAPDH/UDG gene was dependent on the proliferative state of the cell; and (ii) a correlation existed between the transcription of this gene and the level of uracil DNA glycosylase enzyme activity.
