MCT1 and CD147 gene polymorphisms in standardbred horses.

The research studies the genetic differences in horses that may affect lactate transport in their muscles. It specifically focuses on the variants of MCT1 and CD147 genes which facilitate this process. The results found some genetic differences but these do not seem to be linked to muscle health or lactate transport.

Objective of the Research

• The research aimed at exploring the genetic differences within the MCT1 and CD147 genes in Standardbred horses. These two genes play a critical role in the lactate transport process which is crucial for muscle function. The study sought to examine if any variations in these sequences were connected to higher or lower lactacyte transport activities or signs of myopathy.

Methodology

• The research was conducted using muscle biopsy samples taken from three healthy horses and seven horses with myopathy symptoms following intense exercise as reported by their owners.
• The DNA and RNA were isolated from these samples and subjected to PCR analysis and sequencing to decipher the genetic sequences of MCT1 and CD147 in these horses.

Findings

• From the sequencing, PCR fragments covering 100% of MCT1 and 70% of CD147 coding region were obtained.
• The analysis revealed a single nucleotide polymorphism (SNP) each in MCT1 and CD147 genes. Both SNPs resulted in an amino acid alteration.
• However, these SNPs did not seem to be responsible for variations in lactate transport or signs of myopathy, contrary to what was initially assumed.

Conclusions

• The researchers conclude that extensive data from more samples is necessary for deriving any substantial conclusions regarding the significance of the SNPs identified.
• Furthermore, they postulated that full sequence coverage of the CD147 coding region could be a potential area of exploration.
• Finally, the molecular probes created during this research could potentially be employed to study the gene regulation aspects of lactate transport in the future.
