We have demonstrated previously that GRO-alpha then stimulates HIV-1 replication in both T lymphocytes and macrophages.
These results indicate that PARP-1 is required for efficient HIV-1 replication in human cells.
The role of poly (ADP-ribosyl) ation in chromatin replication and the activity of poly (ADP-ribose) synthetase in the newly synthesized and old chromatin was studied.
When the nuclear fraction was incubated with (32P) NAD in the presence of nicotinamide , an inhibitor of poly (ADP-ribose) synthetase , some proteins with a molecular mass of 14.4 -21.5 kDa were ADP-ribosylated.
