The protein levels of TβRI and TβRII in jejunal mucosa during the 2 weeks after weaning.

<p>(A) shows representative blots of TβR I, TβR II proteins expression and β-actin on 0, 3, 7 and 14 post-weaning, respectively. (B) shows relative TβR I and TβR II proteins expression. ^a,b,Mean values with unlike letters were significantly different (<i>P</i><0.05). Values are means and standard deviations represented by vertical bars. The value of protein expression was the ratio of the densitometry units of TβR I, TβR II protein and β-actin. The control sample on day 0 post-weaning was used as the reference sample. The protein expression of all samples was expressed as fold changes, calculated relative to the control group on day 0 post-weaning.
