Hypothesis
To verify the accuracy of collagen-specific SNP mutation loci of Kele pigs selected by whole genome resequencing and to excavate collagen-related genes.
Conclusion
The study identified 307 genes related to collagen traits in Kele pigs, with significant expression of COL9A1 and COL6A5 in skin tissues and COL4A4 and COL4A3 in kidney tissues.
Supporting Evidence
- Whole genome resequencing identified 4,570 high-impact mutation sites in Kele pigs.
- COL9A1 and COL6A5 genes were significantly expressed in skin tissues.
- COL4A4 and COL4A3 genes were significantly expressed in kidney tissues.
- 14 SNP mutation sites were validated through Sanger sequencing.
Takeaway
Scientists studied Kele pigs to find out which genes help make collagen, a protein that affects meat quality, and discovered important genes that are active in their skin and kidneys.
Methodology
Whole genome resequencing was used to identify collagen-related genes, followed by Sanger sequencing and RT-qPCR for validation.
Potential Biases
Potential bias in gene selection and expression analysis due to the limited sample size.
Limitations
The study primarily focused on a specific breed and may not be generalizable to other pig breeds.
Participant Demographics
Kele pigs from Hezhang County, Bijie City, Guizhou Province, China.
