Detection of HSP mRNA Transcription in Transport Stressed Pigs by Fluorescence Quantitative RT-PCR

The RNA transcripted in vitro was used as the standard quantitative template to make the standard curve and establish the fluorescence quantitative RT-PCR (FQ-PCR) method. By means of FQ-PCR, the transcription changes of HSP70 and HSP90 mRNA in the livers and hearts of transport stressed pigs were studied. The level of HSP70 mRNA transcription increased continuously from the beginning of transportation. The inductions of HSP70 mRNA transcription in the livers and hearts of 10 h transport stressed pigs were 2.5 and 4.1 times higher than that of the un-transport stressed pigs (P < 0.01). However, the transcription levels of HSP90 mRNA in the livers and hearts decreased with the transport stress.
