15522829 Anfuso CD, Assero G, Lupo G, Nicotra A, Cannavo G, Strosznajder RP, Rapisarda P, Pluta R, Alberghina M: Amyloid beta (1-42) and its beta (25-35) fragment induce activation and membrane translocation of cytosolic phospholipase A2 in bovine retina capillary pericytes. Biochim Biophys Acta. 2004 Nov 8;1686(1-2):125-38.

Treatment with inhibitors (AACOCF (3), staurosporine and cycloheximide) resulted in a sharp decrease in basal and stimulated cPLA (2) activity.

IL-1beta-induced cPLA2 expression and PGE2 production was inhibited by actinomycin D and cycloheximide, indicating the involvement of transcriptional and translational events in these responses.

In vivo, cycloheximide strongly inhibits the breakdown of PtdIns, and to a lesser extent PtdCho.
The genome of the yeast, Saccharomyces cerevisiae, contains three highly similar genes coding for phospholipases B/lysophospholipases.

16464966 Balzary RW, Cocks TM: Lipopolysaccharide induces epithelium- and prostaglandin E (2)-dependent relaxation of mouse isolated trachea through activation of cyclooxygenase (COX)-1 and COX-2. J Pharmacol Exp Ther. 2006 May;317(2):806-12. Epub 2006 Feb 7.

The LPS antagonist polymixin B; the nonselective COX inhibitor indomethacin; the selective COX-1 and COX-2 inhibitors 5-(4-chlorophenyl)-1-(4-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazole (SC560) and 4-[5-(4-chlorophenyl)-1-(trifluoromethyl)-1H-pyrazol-1-yl]-benzenesulfonam ide (SC236), respectively; the transcription inhibitor actinomycin D; the translation inhibitor cycloheximide; the p38 mitogen-activated protein kinase (p38 MAPK) inhibitor 4-(4-fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)-1H-imadazole (SB203580); and a combination of the mixed DP/EP1/EP2 receptor antagonist 6-isopropoxy-9-xanthone-2-carboxylic acid (AH6809) and the EP4 receptor antagonist 4'-[3-butyl-5-oxo-1-(2-trifluoromethyl-phenyl)-1-5-dihydro-[1,2,4] triazol- 4-ylmethyl]-biphenyl-2-sulfonic acid (3-methyl-thiophene-2-carbonyl)-amide (L-161982) all abolished relaxation to LPS, giving instead slowly developing, small contractions over 60 min.
Activation of both COX-1 and COX-2 seems to be essential for this novel response to LPS, which also involves cPLA (2), p38 MAPK, NF-kappaB, and an unidentified NF-kappaB-independent, labile regulatory protein.
