Abstract: | This test was designed to study the expression of POTs (PepT1, PepT2, PHT1 and PHT2) mRNA in calves'tissues.Tissue-specific expression of the mRNA corresponding to peptide transporter protein in four 3-month-old Chinese Holstein calves was examined by relative quantitative RT-PCR analysis.The results showed that the expression of PepT1 mRNA in the rumen was extremely significantly higher than that in the heart and muscle (P<0.01);The expression of PepT2 mRNA in the liver and kidney was extremely significantly higher than that in the heart, spleen, thymus, muscle, rumen, reticulum, omasum and abomasum (P<0.01);The expression of PHT1 mRNA in the lung and spleen was extremely significantly higher than that in the heart and muscle (P<0.01);The expression of PHT2 mRNA in the lung and thymus was significantly higher than that in the heart, liver, kidney, spleen, muscle, rumen, reticulum, omasum and abomasum (P<0.05).The results indicated that PepT1, PepT2, PHT1 and PHT2 mRNA were respectively abundantly expressed in rumen, kidney and liver, spleen and lung, lung and thymus. |
