1 Acetylation of polyamines by spermidine/spermine N(1)-acetyltransferase (SSAT) has been implicated in their degradation and/or export out of the cell. Polyamines spermidine/spermine N1-acetyltransferase 1 Homo sapiens
2 Acetylation of polyamines by spermidine/spermine N(1)-acetyltransferase (SSAT) has been implicated in their degradation and/or export out of the cell. Polyamines spermidine/spermine N1-acetyltransferase 1 Homo sapiens
3 The relationship of SSAT to polyamine pool dynamics and cell growth is not yet clearly understood. Polyamines spermidine/spermine N1-acetyltransferase 1 Homo sapiens
4 Growth inhibition could not be prevented with exogenous polyamines due to a previously unrecognized ability of SSAT to rapidly acetylate influxing polyamines and thereby prevent restoration of the endogenous pools. Polyamines spermidine/spermine N1-acetyltransferase 1 Homo sapiens
5 Growth inhibition could not be prevented with exogenous polyamines due to a previously unrecognized ability of SSAT to rapidly acetylate influxing polyamines and thereby prevent restoration of the endogenous pools. Polyamines spermidine/spermine N1-acetyltransferase 1 Homo sapiens
6 Overall, the findings demonstrate that conditional overexpression of SSAT lowers polyamine pools, inhibits cell growth, and markedly enhances growth sensitivity to certain analogs. Polyamines spermidine/spermine N1-acetyltransferase 1 Homo sapiens
