CysLTR2 mRNA expression of ht1 ^+/+ or ht2 ^+/+ EBV-infected B cell lines. After B cell lines were cultured with or without PMA (10 ng/ml)/ionomycin (2 μM) for 24 h, the mRNA expression of CysLTR2 was analyzed by RT--PCR. (A) The intensities of PCR products were measured using a densitometer, and compared between ht1 ^+/+(n = 6) and ht2 ^+/+ (n = 6) B cell lines. (B) The data are presented as the mean ± SEM. * P < 0.05 calculated using a Mann--Whitney U-test for comparing PMA/ionomycin-treated ht1 ^+/+ or ht2 ^+/+ B cell lines. † P < 0.01 calculated using Wilcoxon's signed-ranks test for comparing PMA/ionomycin-treated and untreated ht2 ^+/+ B cell lines.
