Gene expression of CATs [CAT-1 (a), CAT-2 (b) and CAT-3 (c)] in chicken intestinal epithelial cells stimulated with C. perfringens. Cells were cultured for 6 h in arginine-free DMEM/F12 containing 0, 50, 400 μmol/L arginine followed by incubating with or without C. perfringens for 4 h. CAT, cationic amino acid transporter. The results are expressed as means ± SEM (n = 6). Bars sharing different lowercase letters differ markedly (P < 0.05)
