Embryonic day 19 fetal rat lung explants, cultured for 24 h, under either control condition (without B-YL or PGZ supplementation) or treated with B-YL (100 mg/kg BW) alone or with PGZ (0.5, 1 or 2 mg/kg BW) + B-YL (100 mg/kg BW), demonstrated significant increases in PPARγ, SP-C, and CCT-α protein levels, as determined by Western analysis, along with a significant increase in [3H]choline incorporation into disaturated phosphatidylcholine (p <0.05 vs. control; N=3).
