Comparison of myocardial mRNA expression levels of various types of phospholipase A₂ (PLA₂) between cytosolic PLA₂ (cPLA₂) wild-type (cPLA₂α^+/+) and knockout (cPLA₂α^−/−) mice at baseline. Real-time quantitative PCR analysis of various types of PLA₂ mRNA expression was performed in the left ventricle (LV) from cPLA₂α^+/+ (filled bars) and cPLA₂α^−/− (open bars) mice. The levels of mRNA expression normalized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA expression and expressed relative to the LV cPLA₂α^+/+ mice (=1). nd, Not detectable; n = 5∼7 mice. sPLA₂, secretory PLA₂; iPLA₂, Ca²⁺-independent PLA₂.
