Characterizing the Key Metabolic Pathways of the Neonatal Mouse Heart Using a Quantitative Combinatorial Omics Approach. Characterizing the Key Metabolic Pathways of the Neonatal Mouse Heart Using a Quantitative Combinatorial Omics Approach

The heart of new-born mouse has exceptional capacity to regenerate from myocardial injury. However, the mouse heart loses this capacity within the first week of its life. In order to elucidate the molecular mechanisms taking place in the mouse heart during the loss of its regenerative potential, a systematic comparison of 1-day and 7-day-old mouse hearts was performed at the proteomic, metabolomic, and transcriptomic levels. Overall design: RNA-seq gene expression of hearts of postnatal day 1 and day 7 Hsd:ICR(CD-1®) male mice
