Phosphatidylcholines 193-212 phospholipase A2 group VI Rattus norvegicus 97-106 11358821-4 2001 Addition of 0.1-10 microM doxorubicin to these cells led to a concentration- and time-dependent inhibition of total iPLA(2), as measured using (16:0, [(3)H]18:1) plasmenylcholine and phosphatidylcholine substrates in the presence or absence of calcium. Phosphatidylcholines 183-202 phospholipase A2 group VI Rattus norvegicus 116-123 10827200-7 2000 Analysis of molecular species of microsomal phosphatidylcholine and phosphatidylethanolamine by electron spray tandem mass spectrometry revealed that the enrichment of oleoyl moieties was altered by the treatment of iPLA(2) antagonist. Phosphatidylcholines 44-63 phospholipase A2 group VI Rattus norvegicus 216-223 10461922-4 1999 Under optimal conditions, the iPLA2 revealed the following substrate preference toward the fatty acid chain in the sn-2 position of phosphatidylcholine: linoleoyl > palmitoyl > oleoyl > arachidonoyl. Phosphatidylcholines 132-151 phospholipase A2 group VI Rattus norvegicus 30-35 9746498-5 1998 With phosphatidylcholine as substrate, TNF-alpha decreased both cytosolic and membrane-associated iPLA2 activities.
