Abstract：
:This study aimed to assess platelets as a possible model for screening the accumulation of mitochondrial DNA mutations, particularly during normal ageing. For this purpose we isolated platelets from young and old donors selected by lack of systemic and haematological diseases. We studied the accumulation of a particular deletion (4977-bp deletion) that usually accumulates in an age-related manner in different post-mitotic tissues, such as brain, heart and skeletal muscle, and in some non-post-mitotic tissues (skin, liver). Using different primers, we failed to detect this particular species of deletion in platelets both from young and old individuals. However, we cannot exclude the presence of other species of deletions or point mutations affecting the mitochondrial DNA in platelets during the aging process.
