1 Cell growth inhibition by prostaglandin A2 results in elevated expression of gadd153 mRNA. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
2 Treatment of Hela cells with prostaglandin A2 (PGA2) resulted in a marked inhibition of cell proliferation which was associated with a significant induction of gadd153 mRNA, a member of a novel class of genes associated with growth arrest and DNA damage. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
3 Treatment of Hela cells with prostaglandin A2 (PGA2) resulted in a marked inhibition of cell proliferation which was associated with a significant induction of gadd153 mRNA, a member of a novel class of genes associated with growth arrest and DNA damage. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
4 Induction of gadd153 mRNA was specific to prostaglandins capable of arresting cell growth and was dose-dependent with the maximum effect seen at 36 microM PGA2. Prostaglandins DNA damage inducible transcript 3 Homo sapiens
5 Induction of gadd153 mRNA was specific to prostaglandins capable of arresting cell growth and was dose-dependent with the maximum effect seen at 36 microM PGA2. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
6 Induction was rapid, occurring within 2-4 h and reaching a maximum by 8 h. These effects were reversible as removal of PGA2 resulted in a rapid decline in gadd153 mRNA levels coincident with resumption of cell growth. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
7 PGA2 induction of gadd153 mRNA was completely prevented by the presence of actinomycin D at a concentration sufficient to block transcription and was partially inhibited (50%) by the protein synthesis inhibitor cycloheximide. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
8 PGA2 induction of gadd153 mRNA was completely prevented by the presence of actinomycin D at a concentration sufficient to block transcription and was partially inhibited (50%) by the protein synthesis inhibitor cycloheximide. Dactinomycin DNA damage inducible transcript 3 Homo sapiens
9 PGA2 induction of gadd153 mRNA was completely prevented by the presence of actinomycin D at a concentration sufficient to block transcription and was partially inhibited (50%) by the protein synthesis inhibitor cycloheximide. Cycloheximide DNA damage inducible transcript 3 Homo sapiens
10 The presence of the protein kinase inhibitor 2-aminopurine decreased the PGA2 induction of gadd153 mRNA by greater than 90%, suggesting that cellular kinases play a role in the induction of gadd153 by PGA2. 2-Aminopurine DNA damage inducible transcript 3 Homo sapiens
11 The presence of the protein kinase inhibitor 2-aminopurine decreased the PGA2 induction of gadd153 mRNA by greater than 90%, suggesting that cellular kinases play a role in the induction of gadd153 by PGA2. 2-Aminopurine DNA damage inducible transcript 3 Homo sapiens
12 The presence of the protein kinase inhibitor 2-aminopurine decreased the PGA2 induction of gadd153 mRNA by greater than 90%, suggesting that cellular kinases play a role in the induction of gadd153 by PGA2. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
13 The presence of the protein kinase inhibitor 2-aminopurine decreased the PGA2 induction of gadd153 mRNA by greater than 90%, suggesting that cellular kinases play a role in the induction of gadd153 by PGA2. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
14 The presence of the protein kinase inhibitor 2-aminopurine decreased the PGA2 induction of gadd153 mRNA by greater than 90%, suggesting that cellular kinases play a role in the induction of gadd153 by PGA2. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
15 The presence of the protein kinase inhibitor 2-aminopurine decreased the PGA2 induction of gadd153 mRNA by greater than 90%, suggesting that cellular kinases play a role in the induction of gadd153 by PGA2. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
16 Thus PGA2-mediated growth arrest provides a useful model to further define the role of gadd153 in the negative control of cell growth. prostaglandin A2 DNA damage inducible transcript 3 Homo sapiens
