Summary
Doppel mRNA expression varies significantly across sheep tissues and genotypes. This study highlights distinct Doppel gene expression patterns in ARR/ARQ and ARH/ARQ sheep, impacting future prion disease research.
Area of Science:
- Molecular Biology
- Genetics
- Veterinary Science
Background:
- Doppel is a homologue of the cellular prion protein (PrP)-like protein (PrPC).
- Understanding Doppel gene expression is crucial for prion-related research.
Purpose of the Study:
- To quantify Doppel mRNA expression in various sheep tissues.
- To investigate the influence of PrP gene genotypes (ARR/ARQ and ARH/ARQ) on Doppel mRNA levels.
Main Methods:
- Tissue samples were collected from the central nervous system, lymphoid system, digestive tract, and reproductive organs of sheep.
- Total RNA was isolated, and Doppel mRNA expression was quantified using real-time RT-PCR with SYBR Green.
Main Results:
- Doppel mRNA expression was highest in the ovary, hypothalamus, and brain.
- Significant differences in Doppel mRNA expression were observed between the ARR/ARQ and ARH/ARQ genotypes in the brain, ileum, cecum, rectum, colon, and uterus.
Conclusions:
- Doppel mRNA expression exhibits significant variation based on sheep PrP genotypes.
- These findings provide valuable insights into the differential expression of Doppel and its potential relationship with PrP in sheep.
