Molecular Characterization of EGLN1 Gene in Fast and Slow Moving Animals of Diverse Terrain

Abstract

Background: Process of animal migration from their habitat to a new environment is always problematic due to low adaptive tendency, which ultimately affect their production, behavior and overall performance. Current study is focused to explore the sequence diversity of EGLN1 gene in relation to animal acclimatization at higher altitude under deprived oxygen or ability of better utilization of oxygen which is considered to be liable for their agility in diverse terrains. Fast and slow moving animals of plain and hilly terrains are potential species to study this phenomenon. Methods: Molecular characterization of EGLN1 gene was performed in sheep, goat, buffalo and camels of Pakistan as slow moving candidate species, while tiger, leopard, wolf, ibex, urial and markhor as fast moving candidate species of diverse terrains by extraction their DNA from whole blood, followed by PCR amplification and sequence analysis of EGLN1 gene through BioEdit software. Later on, certain bioinformatics tools like MEGA, protparam and blast2sequence are used for the characterization of the normal and mutant EGLN1 protein. Results: Current study revealed that goat and camel showed a nucleotide change at c.810 position. While all fast moving animals of higher altitude showed a nucleotide change at position c.406 except one sample of markhor. Conclusion: Current study will assist to have an idea of sequence diversity of aforementioned candidate gene responsible for adaption of animals in oxygen deprived environment of diverse terrain and may be responsible for their agile behaviour of movement.
