Gene expression of AA sensors in porcine jejunum exposed to Lys. Gene expression (mRNA abundance) of AA receptors and transporters (T1R1 (A), T1R3 (B), CaSR (C), mGluR1 (D), mGluR4 (E), SLC7A1 (F) and SLC7A2 (G)) in the proximal jejunum of young pigs following 1 h incubation with a KRB/HEPES buffer containing 0 (control) or 20 mmol/L Lys. Data are presented as mean ± SEM (n = 6). P values indicate a statistical trend: 0.05 ≤ P ≤ 0.10
