Background: Cardiac transcription factors are master regulators during heart development. Recently, some were shown to transdifferentiate noncardiac mesoderm cells and cardiac fibroblasts into cardiomyocytes. However, the individual roles of each transcription factors in activating cardiac gene program have not been elucidated. We examined cardiac-specific and genome-wide gene expression in fibroblasts induced with cardiac transcription factors Nkx2.5 (N), Tbx5 (T), Gata4 (G), Myocardin (M) alone or different combinations.

View SamplesAccounting for transcriptional features of endurance adaptations to training is important and could help elucidate the high variability in oxygen uptake (VO2) response. We aimed to identify whole-transcriptome signatures of an endurance training protocol in whole-blood (leukocytes), PBMCs and skeletal muscle tissue of the same group of individuals in a controlled environment.

View Samples19 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.

View SamplesThere is an association between transcriptome and the exercise-related phenotype. Peripheral blood cells suffer alterations in the gene expression pattern in response to perturbations caused by exercise. The acute response to endurance activates stress and inflammation, as well as growth and tissue repair responses.
PBMCs express a transcriptome signature predictor of oxygen uptake responsiveness to endurance exercise training in men.
