Abstract

This study was conducted to investigate the effects of zearalenone (ZEA) on apoptosis of chicken splenic lymphocytes in vitro. The spleens of some healthy Isabel roosters of 40 to 60 days of age were taken under sterile condition and the lymphocyte suspensions were prepared. Chicken splenic lymphocytes were treated with 0 (control), 0.10, 0.40, 1.60, 6.25 and 25.00 μg/mL ZEA for 48 h in vitro, and the apoptosis rate, necrotic rate, cell mitochondria membrane potential, intracellular reactive oxygen species (ROS) content and the mRNA expression levels of B lymphocytoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), Bak-1, p53 and caspase-3 as well as their protein contents in the supernatant were measured. The results showed that compared with the control group, ZEA significantly or extremely significantly increased the apoptosis rate, necrotic rate, ROS content, contents of p53, Bax, Bak-1 and caspase-3 in the supernatant and the mRNA expression levels of intracellular p53, Bax, Bak-1 and caspase-3 (P<0.05 or P<0.01), which were higher and higher with ZEA concentration increasing. Whereas the mitochondria membrane potential and Bcl-2 content in the supernatant were extremely decreased in ZEA groups compared with the control group (P<0.01). These results suggest that ZEA induces apoptosis of chicken splenic lymphocytes in a dose-dependent manner.
