Abstract
Among the numerous transmissible spongiform encephalopathies (TSEs), bovine spongiform encephalopathy (BSE) is the most well-known TSEs. It is a potential Creutzfeldt-Jakob (CJD) disease mutation that can be transferred through cattle to humans. In several animals, the prion protein gene (PRNP) is recognized to take active part in TSE vulnerability or tolerance. Previous studies have found indels polymorphism in PRNP gene promoter and intron1 region linked to BSE vulnerability. It's linked with 23 bp indels polymorphism in putative promoter and 12 bp indel in intron 1 of the PRNP gene. The aim of this study was to compare the allele, genotype and haplotype frequencies of PRNP indel polymorphisms in Zhongdian Yak (Bos grunniens) (YK), Zhongdian Yellow cattle (Bos taurus) (YC) and Zhongdian Yakow (Bos primigenius taurus × Bos grunniens) (PK) with worldwide reported healthy or affected BSE cattle, in order to assess their potential resistance to BSE. A comparison of Chinese bovine populations with healthy and BSE-affected German and Swiss cattle from globally was conducted, and result indicating significant difference (p < .001) between healthy and affected cattle. Additionally, as compared to prior studies with Chinese bovine population, the significant results were found. In this study, the allelic frequency D23 finding high deletion in all analyzed Chinese bovine species, and haplotype D12-D23 exhibited a less significant inclination toward susceptibility to BSE.

Abstract
Prion protein, encoded by the prion protein gene (PRNP), plays a crucial role in the pathogenesis of transmissible spongiform encephalopathies (TSEs). Several polymorphisms within the PRNP are known to be associated with influencing bovine spongiform encephalopathy (BSE) susceptibility in cattle, namely two insertion/deletion (indel) polymorphisms (a 23-bp indel in the putative promoter and a 12-bp indel in intron 1), the number of octapeptide repeats (octarepeats) present in coding sequence (CDS) and amino acid polymorphisms. The domestic buffaloes, Bubalus bubalis, are a ruminant involved in various aspects of agriculture. It is of interest to ask whether the PRNP polymorphisms differ between cattle and buffalo. In this study, we analyzed the previously reported polymorphisms associated with BSE susceptibility in Chinese buffalo breeds, and compared these polymorphisms in cattle with BSE, healthy cattle and buffalo by pooling data from the literature. Our analysis revealed three significant findings in buffalo: 1) extraordinarily low deletion allele frequencies of the 23- and 12-bp indel polymorphisms; 2) significantly low allelic frequencies of six octarepeats in CDS and 3) the presence of S4R, A16V, P54S, G108S, V123M, S154N and F257L substitutions in buffalo CDSs. Sequence alignments comparing the buffalo coding sequence to other species were analyzed using the McDonald-Kreitman test to reveal five groups (Bison bonasus, Bos indicus, Bos gaurus, Boselaphus tragocamelus, Syncerus caffer caffer) with significantly divergent non-synonymous substitutions from buffalo, suggesting potential divergence of buffalo PRNP and others. To the best of our knowledge this is the first study of PRNP polymorphisms associated with BSE susceptibility in Chinese buffalo. Our findings have provided evidence that buffaloes have a unique genetic background in the PRNP gene in comparison with cattle.

Abstract
Bovine spongiform encephalopathy (BSE) is one of the fatal neurodegenerative diseases known as transmissible spongiform encephalopathies (TSEs) caused by infectious prion proteins. Genetic variations correlated with susceptibility or resistance to TSE in humans and sheep have not been reported for bovine strains including those from Holstein, Jersey, and Japanese Black cattle. Here, we investigated bovine prion protein gene (PRNP) variations in Hanwoo cattle [Bos (B.) taurus coreanae], a native breed in Korea. We identified mutations and polymorphisms in the coding region of PRNP, determined their frequency, and evaluated their significance. We identified four synonymous polymorphisms and two non-synonymous mutations in PRNP, but found no novel polymorphisms. The sequence and number of octapeptide repeats were completely conserved, and the haplotype frequency of the coding region was similar to that of other B. taurus strains. When we examined the 23-bp and 12-bp insertion/deletion (indel) polymorphisms in the non-coding region of PRNP, Hanwoo cattle had a lower deletion allele and 23-bp del/12-bp del haplotype frequency than healthy and BSE-affected animals of other strains. Thus, Hanwoo are seemingly less susceptible to BSE than other strains due to the 23-bp and 12-bp indel polymorphisms.

Abstract
This study was conducted to investigate the presence of single nucleotide polymorphisms (SNPs) in the coding region of the bovine prion protein (PrP) gene among healthy and bovine spongiform encephalopathy (BSE-) affected cattle in Slovakia. Denaturing gradient gel electrophoresis (DGGE) and single-strand conformation polymorphism (SSCP) followed by DNA sequencing were used to identify SNPs and variations in octapeptide repeats. Altogether three single nucleotide polymorphisms (g234a, c339t and c576t) and variations in the number of octapeptide repeat units (5 or 6) were found in the analysed part of the prion protein gene. All single nucleotide polymorphisms were silent, causing no amino acid changes. Significant differences (P < 0.05) in the genotype distribution of g234a polymorphism were observed when the homozygous genotype with a mutated allele (caa/caa) was compared to the heterozygous genotype -/cag among healthy and BSE-affected cattle. The homozygous genotype caa/caa was characteristic of the group of BSE-affected cattle. Additionally, the homozygous genotype caa/caa was significant for the group of Simmental crossbreeds among healthy cattle. The allele and genotype distribution of the other polymorphisms was not significantly different among groups of healthy and BSE-affected cattle. The possible influence of a silent mutation on expression of the gene is not clearly determined and needs further investigations.

Abstract
The gayal (Bos frontalis) is a rare semi-wild bovid species in which bovine spongiform encephalopathy (BSE) has not been reported. Polymorphisms of the prion protein gene (PRNP) have been correlated significantly with resistance to BSE. In this study, the coding region of PRNP was cloned and characterized in samples from 125 gayal. A total of ten single nucleotide polymorphisms (SNPs), including six silent mutations (C60T, G75A, A108T, G126A, C357T and C678T) and four mis-sense mutations (C8A, G145A, G461A and C756G), corresponding to amino acids T3K, G49S9, N154S and I252M were identified, revealing high genetic diversity. Three novel SNPs including C60T, G145A and C756G, which have not been reported previously in bovid species, were retrieved. There also was one insertion-deletion (187Del24) at the N-terminal octapeptide repeat region. Alignment of nucleotide and amino acid sequences showed a high degree of similarity with other bovid species. Using phylogenetic analyses it was revealed that gayal has a close genetic relationship with Zebu cattle. In short, preliminary information is provided about genotypes of the PRNP in gayal. This could assist with the study of the pathogenesis of transmissible spongiform encephalopathies and cross species transmission as well as a molecular breeding project for gayal in China.
