Gene Expression of Peroxisome Proliferator-Activated Receptor ? in Mangalica and Large White Pigs

The expression of peroxisome proliferator-activated receptor ? gene (PPAR?) – a major regulator of adipogenesis and intramuscular fat deposition in pigs – was analysed in different tissues of Blonde Mangalica (M) and Hungarian Large White (LW) by means of quantitative reverse transcription PCR. In total, 20 experimental animals were raised and fed under identical conditions, and transported to the abattoir at similar body weight (124.7±10.3 kg; p>0.05). In both breeds highest PPAR? expression was observed in backfat (p0.05). Elevated PPAR? expression was observed in M backfat compared to LW (p
