Project description:Using transcriptomic we looked for changes in large-scale gene expression profiling of leukocytes of hypertensive patients with left ventricular remodeling compared to hypertensive patients without left ventricular remodeling and to control and whether these changes reflect metabolic pathway regulation already shown by positron emission tomography. Genes encoding for glycolytic enzymes were found over-expressed in the group of hypertensive patients with left ventricular remodeling. Expression of master genes involved in fatty acids β-oxidation was unchanged.
Project description:The goal of this study is to examine transcriptomic changes in the left ventricles during the transition from a regenerative to a non-regenerative state in the pig neonatal heart. RNA was isolated from pig left ventricular tissue at postnatal day (P)0, P7, and P15, to compare the regeneration-capable P0 cardiac transcriptomic environment to the non-regenerative timepoints of P7 and P15, in pig hearts.
Project description:Human left ventricular free wall heart tissue was obtained from end-stage heart failure patients at the moment of heart transplantation Left ventricular free wall samples were also obtained from healthy hearts of organ donors, which were not used for transplantation due to size mismatch with available recipients.
Project description:19 paired human left ventricular apex samples were harvested at the time of implant of a left ventricular assist device (PRE) and at the time of explant (POST). The cohort included patients that were clinically classified as "ischemic" (I) showing evidence of coronary artery disease, "non-ischemic" (N) no evidence of coronary artery disease or "acute Myocardial infarction" (IM) myocardial infarction within 10 days of the implant. Tissue was processed and hybridized to the Affymetrix HG-U133A chip. Keywords: other
