Abstract:

To further understand the function of Fas/ FasL system,the Fas and FasL genes of yak were cloned by RT-PCR method and their expressions were analyzed by combination of RT-PCR and immunohistochemistry.A complete cDNA sequences in 2 605 bp of Fas gene and 1 572 bp of FasL gene of yak was obtained.These sequences were highly homology with cattle.Fas and FasL mRNAs were co-expressed in all analyzed tissues except heart which expressed Fas mRNA alone.The two genes strongly co-expressed in liver,spleen,kidney,lymphonodus,thymus and testis.A cytoplasmic form of FasL protein was detected in several cell types of various organs.Fas and FasL were strongly co-expressed in lymphoid organs and immune privilege sites,they were also strongly co-expressed in other tissues like kidney and liver.The results suggested that Fas/FasL system was more complicated.
