Project description:To evaluate the genome-wide changes in gene translational efficiency during the development of heart failure, we performed transverse aortic constriction(TAC) in male C57BL/6 mice. According to our experience, hypertrophy of the left ventricle was observed 2 weeks after TAC. Cardiac decompensation was observed at 5 weeks. We collected left ventricular tissues at 0, 2, 5 weeks after TAC and then performed ribosome footprinting and sequencing.
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: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

Project description:Wild-type C57BL/6N mice were treated with twice-weekly carfilzomib injections for a period of two weeks. Following this treatment, the left ventricular tissues were prepared for tmt-multiplexed mass spectrometry analysis to determine the protein-profiles of the treated hearts as opposed to those of untreated mouse specimens.
