Project description:From this array we would like to know the role of Smyd2 on hypoxic regulated genes mainly angiogenic pathway. We performed overexpressions of Smyd2 and beta galactosidase by adenoviral approach and knockdown of HIF1 and Smyd2 were performed by lipofectamine RNAiMAX.Cardiomyocytes were isolated from neonatal rats at P3.
Project description:We addressed the question of which protein kinases are expressed in cardiomyocytes. We assessed the changes during postnatal development, comparing profiles in rat neonatal ventricular cardiomyocytes (NVMs) with adult ventricular cardiomyocytes (AVMs). Neonatal and adult rat ventricular cardiomyocytes prepared according to established procedures (Marshall et al. PLoS ONE 2010 5(4):e10027; Fuller and Sugden, FEBs Lett. 1989 247:209-12; Rodrigues and Severson In Biochemical Techniques in the Heart (McNeill, J. H., Ed.) pp 101-115, CRC Press, New York.). mRNA expression profiles compared using Affymetrix rat genome 230 2.0 arrays.
Project description:TRIM24 (Tripartite Motif-Containing 24) is a key transcriptional co-regulator involved in various cellular processes, including chromatin remodeling and gene expression. However, its role in cardiomyocytes remains largely unexplored. In this study, we investigated the global proteomic changes associated with TRIM24 overexpression in neonatal rat ventricular cardiomyocytes (NRVCMs) to better understand its function in cardiac biology. NRVCMs were transduced by an Adenovirus overexpressing TRIM24. Protein isolated from the NRVCMs transduced by an Adenovirus overexpressing LacZ was used as control.
Project description:Study on changes in gene expression in primary cultures of neonatal rat ventricular cardiomyocytes to electric stimulation. Through comparing non-stimulated, stimulated and blebbistatin supplemented and stimulated cultures we set out to identify the genes that are specifically activated by electric pulsing separate from cardiomyocyte contractions. After initial recovery phase, primary cultures of neonatal rat ventricular cardiomyocytes were cultured for 3 days without pulsing, with electric pulsing or with electric pulsing combined with blebbistatin. Per treatment: 3 arrays, with samples obtained from 3 separate series of cardiomyocyte isolation and culturing. Per array: sample prepared from pooled (1:1) RNA from duplicate experiments.

Project description:TRIM24 (Tripartite Motif-Containing 24) is a key transcriptional co-regulator involved in various cellular processes, including chromatin remodeling and gene expression. However, its role in cardiomyocytes remains largely unexplored. In this study, we investigated the global proteomic changes associated with TRIM24 downregulation in neonatal rat ventricular cardiomyocytes (NRVCMs) to better understand its function in cardiac biology. NRVCMs were transduced by an Adenovirus with a synthetic microRNA targeting TRIM24. Protein isolated from the NRVCMs transduced with a scrambled microRNA was used as control.
Project description:This experiment investigated the effects of the novel bromodomain inhibitor 3i-1248 in neonatal mouse ventricular cardiomyocytes with and without neurohormonal stimulation with ET-1.
