Hypothesis

The study investigates the genomic region containing the SPRN gene in sheep to understand its role in TSE susceptibility.

Conclusion

The SPRN gene in sheep shows high homology with bovine and human sequences and is primarily expressed in brain tissue.

Supporting Evidence

  • The SPRN gene was identified for the first time in sheep.
  • A BAC mini-contig covering approximately 200,000 bp was constructed.
  • High levels of SPRN expression were found in brain tissues.

Takeaway

Scientists studied a gene in sheep that might help explain how they get sick from prions, and they found it is mostly active in the brain.

Methodology

The study involved constructing a BAC mini-contig, sequencing the SPRN gene, and performing transcription profiling in various tissues.

Limitations

The study is limited by the lack of publicly available sequences in sheep or related species for comparison.
