Effects of hydrocortisone (HC), injected in 11 day old pups, on sucrase-isomaltase (SI) induction and cytokine expression. (A) Representative RT-PCR assays detecting SI, transforming growth factor β1 and β2 (TGF-β1, TGF-β2), transforming growth factor α (TGF-α), tumour necrosis factor α (TNF-α), interleukin 1β (IL-1β), and β-actin mRNAs at postnatal day 12: lanes 1, control; lanes 2, treated animals. (B) Densitometric analysis of SI, TGF-β1, TGF-β2, TGF-α, TNF-α, and IL-1β bands normalised to values of β-actin as internal control from three independent experiments. Results are illustrated in the HC treated tissues as percentages of control values. *p< 0.05, ** p<0.01, significant differences between HC treated and control animals (unpaired t test).
