| Study Title | Metabolomics studies on human cardiac samples |
| Study Summary | Targeted metabolomics was performed to measure polar metabolites in both positive and negative ionization mode on left ventricular tissue acquired from pre-mortem healthy donor hearts as classified by formal pathological examination and stored at the Sydney Heart Bank. The minimum number of observations for young (age ≤ 25 years) and old (age ≥ 50 years) cohorts using liquid chromatography-tandem mass spectrometry (LC-MS/MS). |

| Project Title: | The Human Cardiac “Age-OME”: Age-specific changes in myocardial molecular expression |
| Project Type: | MS analysis |
| Project Summary: | A substantial proportion of the World’s population is ageing. One of the most significant risk factors for heart disease is ageing. However, we do not understand how the human heart changes with age. Taking advantage of a unique set of pre-mortem, cryopreserved, non-diseased human hearts, we performed multi-omic analyses (transcriptomics, proteomics, metabolomics and lipidomics), coupled with biological computational modelling in younger (<25 years old) and older hearts (>50years old) to describe the molecular landscape of human cardiac ageing. In older hearts, we observed a downregulation of proteins involved in calcium signalling and of the contractile apparatus itself. In addition, we found a potential counteractive upregulation of central carbon generation of fuel, upregulation of glycolysis and increases in long-chain fatty acids. This is the first molecular data set of normal human cardiac ageing, which may have important implications for the development of age-related heart disease. |
