Project description:NIH3T3 cell transiently transfected with myocardin-EGFP or EGFP. Transfection: Lipofectamine 2000 according to the manufacturers instructions (Invitrogen).
Project description:Effect of the loss of both miR-1/133a clusters on the embryonic heart. Please note: dKO means it is a double KO of the two miR-1/133a clusters in the mouse. Control means we do not use just WT but also some heterozygous animals to compare to dKOs, however these controls do not have a phenotype. Transgene negative: these are littermates of the myocd transgenic animals that do not carry a transgene.
Project description:Inhibition of myostatin signaling induces strong skeletal muscle growth making it an attractive target to treat muscle wasting and sarcopenia. However, the biological function of myostatin in the heart is barely understood. We demonstrate that conditional inactivation of myostatin in the adult murine heart leads to cardiac hypertrophy, heart failure and increased lethality. To induce cardiomyocyte specific loss of myostatin a conditionally active Mstn^fl/fl allele was generated by insertion of loxP elements upstream and downstream of exons 1 and 2 of the mouse myostatin gene. The selection cassette was removed in vivo by flp-recombination. To inactivate myostatin, mice were mated to alphaMyHC-MCM mice (Sohal, DS, et al. (2001) Circulation Research 89, 20-25). Cre-recombination was achieved by intraperitoneal administration of Tamoxifen (40 mg/kg) for 5 consecutive days. The respective control alphaMyHC-MCM animals were equally treated.
Project description:Expression analysis of wild-type SAOS cells and SAOS cells transiently transfected with RB, SMYD2, or RB and SMYD2. Four samples of wild-type, rb1, smyd2 and rb1-smyd2 were analyzed on the Human Genome U133 Plus 2.0 array.
Project description:To identify potential transcriptional targets of Smyd2, we performed ChIP-sequencing (ChIP-seq) analysis in renal epithelial cells with an anti-Smyd2 antibody. We identified 91 potential Smyd2 target genes in Pkd1 wild type MEK cells and 116 potential Smyd2 target genes in Pkd1 null MEK cells. There were 14 genes identified in both Pkd1 wild type and null MEK cells. Thus, the number of potential Smyd2 target genes in Pkd1 null MEK cells are 116 - 14 = 102 genes
