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:Using the highly sensitive RNA array, we assessed the effect of 11β-HSD1 and BVT.2733 on modulating RNAs expression in the neonatal rat ventricular cardiomyocytes.
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:The adenovirus carrying Mettl14 gene infects primary neonatal mouse cardiomyocytes, which is in contrast with the primary neonatal mouse cardiomyocytes infected with empty virus. The purpose is to explore the effect of Mettl14 on the global mRNA m6A modification level in primary neonatal rat cardiomyocytes.
Project description:Expression profiles of microRNAs in neonatal (isolated from day0 newborn rats) and adult rat cardiomyocytes (isolated from 2month old rats) Two condition experiment; Biological replicates: 7 samples of cardiomyocytes from neonatal rats (from independent isolations); 6 samples of cardiomyocytes isolated from adult animals (from independent isolations)
Project description:RNA-Seq results of adult mouse cardiomyocytes with Jmjd4 knockout and neonatal rat cardiomyocytes with Jmjd4 knockdown. To investigate the role of Jmjd4 in dilated cardiomyopathy, we performed gene expression profiling with RNA-Seq results from heart samples of MCM+ Jmjd4f/f and control Jmjd4f/f mice, as well as neonatal rat ventricuar cardiomyocytes (NRVCs) treated with si-Jmjd4 and si-NC control.
Project description:miR-222 overexpression leads to promotion of proliferation and hypertrophy and inhibition of apoptosis in in primary neonatal rat ventricular cardiomyocytes (NRVMs). Isolated primary neonatal rat ventricular cardiomyocytes were plated in 6 cm BD Primaria tissue culture dishes. Transfection of microRNA precursors or scramble control (0.4 μM) was carried out using Lipofectamine RNAiMAX (Invitrogen) as recommended by the manufacturer. Forty-eight hours after transfection, RNAs from cultured cells and tissues were isolated with Tryzol (Invitrogen) following the manufacturesâ?? manuals. Total RNA was harvested and submitted to the Dana-Farber Cancer Institute Molecular Diagnostics Laboratory for assay. These results revealed miR-222 regulated gene expression in primary neonatal rat ventricular cardiomyocytes. Gene expression in NRVM cells tranfected with control scramble precursor (4 samples) or miR-222 precursor (4 smaples ) was evaluated using Affymetrix Rat Genome 230 v2.0.
