Effect of Eimeria spp. challenge a and methionine supplementation b on the expression of genes encoding y+LAT-1, B0AT1, CAT-1, and PEPT1 in the jejunum of broilers. Results are expressed as arbitrary units, AU, and are presented as mean and standard error. a,b Different letters represent significant differences between treatments by the Tukey test, P < 0.05. UC = unchallenged broilers; EC = Eimeria-challenged broilers. NS = non-supplemented diet; dl-Met = diet supplemented with free methionine; dl-MMet = diet supplemented with methionine dipeptide. y+LAT-1 = neutral and cationic amino acid transporter 1 gene. CAT-1 = cationic amino acid transporter 1 gene; B0AT1 = system B0 neutral amino acid transporter 1 gene; PEPT1 = peptide transporter 1 gene
