A disintegrin and metalloprotease-15 (ADAM-15) is a potential novel regulator of inflammatory response and tissue remodelling, which is thought to have the ability to attenuate the cardiac function resulting from myocardial infarction (MI). Therefore, the aim of our study was to investigate the expression of ADAM-15 in rat MI. Wistar rats were subjected to MI by ligation of the left anterior descending coronary artery. Euthanasia was performed at 1, 3, 7 and 14 days following MI. The mRNA and protein expression levels of ADAM-15 were detected respectively by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. The localization of ADAM-15 protein was observed by immunohistochemistry. Compared with sham-MI, the expression of ADAM-15 in MI increased at day 1, reached to maximum at day 3, decreased at day 7 and day 14 gradually. In addition, we also found that the localization of ADAM-15 was mainly at cardiac myocytes in the border area of MI and some macrophages in the border and infarcted areas. This study revealed a significant difference of ADAM-15 expression in rat MI and indicated that ADAM-15 maybe one of the important factors involved in inflammatory response and cardiac remodelling of rat MI.
