Hypothesis

Bovine animals with reduced prion protein (PrP) would be tolerant to BSE.

Conclusion

The most effective siRNA for knocking down bPRNP was found to be 21 mer GGGGAGAACTTCACCGAAACT, providing a basis for further studies in vivo.

Supporting Evidence

  • Four siRNA expression plasmid vectors were tested for their ability to knock down bPRNP.
  • Six target sites of bPRNP were designed and evaluated for effectiveness.
  • Longer siRNAs were generally less effective than shorter ones.

Takeaway

Scientists are trying to make cows that can't get mad cow disease by reducing a specific protein in their bodies using a special technique called RNA interference.

Methodology

The study involved creating siRNA expression plasmid vectors and testing their effectiveness in cultured mammalian cells.

Limitations

The study was conducted in vitro, and the effectiveness in vivo remains to be confirmed.
