Nicotine 226-234 phospholipase A2 group IB Homo sapiens 281-297 31492433-1 2019 We investigated the relationship between the rs10798059 (BanI) and rs4375 polymorphisms in the phospholipase A2 (PLA2)G4A and PLA2G6 genes and the risk of nicotine dependence in 263 Croatian patients with schizophrenia. Nicotine 155-163 phospholipase A2 group IB Homo sapiens 95-111 9873232-3 1999 Therefore, we studied: (a) the influence of nicotine and cotinine on the effects of PGE2 on placental vasculature in perfused human placental cotyledon, and (b) the activation of placental phospholipase A2 (PLA2) by nicotine and cotinine using 1-palmitoyl-2-[1-14C]arachidonyl-phosphatidylethanolamine (PE, 2.2 nmol) as substrate. Nicotine 216-224 phospholipase A2 group IB Homo sapiens 189-205 9873232-6 1999 Nicotine (2 microg/ml) prevented the effect of PGE2; (2) both cotinine (EC50 470-500 fmol/l) and nicotine (EC50 18-32 pmol/l) activated PLA2 in human placental tissues. Nicotine 0-8 phospholipase A2 group IB Homo sapiens 136-140 9873232-6 1999 Nicotine (2 microg/ml) prevented the effect of PGE2; (2) both cotinine (EC50 470-500 fmol/l) and nicotine (EC50 18-32 pmol/l) activated PLA2 in human placental tissues. Nicotine 97-105 phospholipase A2 group IB Homo sapiens 136-140 9873232-7 1999 These observations indicated that cotinine was more potent than in nicotine activating PLA2 and potentiating the vasoconstrictive effects of PGE2 on fetal placental circulation. Nicotine 67-75 phospholipase A2 group IB Homo sapiens 87-91 9067314-0 1997 Nicotine-induced inhibition of neuronal phospholipase A2. Nicotine 0-8 phospholipase A2 group IB Homo sapiens 40-56 9067314-7 1997 In fact, using the fluorogenic phospholipase A2 substrate 1,2-bis-(1-pyrenedecanoyl)-sn-glycero-3-phosphocholine, (-)-nicotine was found to inhibit both particulate and soluble phospholipase A2 activities from striatal neurons. Nicotine 114-126 phospholipase A2 group IB Homo sapiens 31-47 9067314-7 1997 In fact, using the fluorogenic phospholipase A2 substrate 1,2-bis-(1-pyrenedecanoyl)-sn-glycero-3-phosphocholine, (-)-nicotine was found to inhibit both particulate and soluble phospholipase A2 activities from striatal neurons. Nicotine 114-126 phospholipase A2 group IB Homo sapiens 177-193 9685679-4 1998 (-)Nicotine inhibits the AbetaP activation of phospholipase A2, with an IC50 of 76 microM and of phospholipase D with an IC50 of 252 microM. Nicotine 3-11 phospholipase A2 group IB Homo sapiens 46-62 9685679-8 1998 Exposure of LA-N-2 cells to (-)nicotine for 2 h resulted in the blockade of phospholipase A2 activation by kainate and AbetaP but did not affect the ability of quisqualate and AbetaP to activate phospholipase D. These data suggest that if the nicotine inhibition of AbetaP activations is receptor occupancy mediated then it is by an atypical receptor type.
