The cDNA Sequences of Equine Antioxidative Enzyme Genes Cu/Zn-SOD and Mn-SOD, and These Expressions in Equine Tissues

摘要

References(25) Cited-By(2) The entire cDNA sequences were determined by reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) techniques for equine copper/zinc superoxide dismutase (Cu/Zn-SOD) and manganese superoxide dismutase (Mn-SOD) through the use of total RNA extracted from the testis of an adult Thoroughbred. The results revealed a protein coding region for equine Cu/Zn-SOD with bases totaling 465 bp, accompanied by an estimated 154 residues of amino acids. As for equine Mn-SOD, its coding region contained a total of 669 bp and an estimated 222 residues of amino acids. Further, the expression of Cu/Zn-SOD and Mn-SOD genes were confirmed in the equine tissues by RT-PCR and in situ hybridization.
