Aged hearts exhibit reduced tolerance to ischemia-reperfusion, together with altered structure and post-ischemic remodelling. The molecular bases of such changes are unclear. Using cDNA microarrays and quantitative RT-PCR we characterized shifts in gene expression patterns with aging in normoxic and post-ischemic (20 min global ischemia, 60 min reperfusion) murine hearts (young: 2-4 months; aged: 16-18 months). We identified an age-associated up-regulation of transcripts involved in cell death, ...[more]
