(Submitter supplied) Overall goal: To elucidate the function served by Rpl3L in heart. Purpose of analysis: To determine effects of Rpl3L-deficiency on translational mRNA profile in heart. Experimental structure: Polysomes and monosomes were fractionated from cardiac ventricles and associated RNA extracted for library generation and differential gene expression analyses between wild-type and Rpl3L-null samples, using standard RNAseq pipeline.

(Submitter supplied) The ribosomal protein L3-like (RPL3L) is a striated muscle-specific ribosomal protein, and mutations in human RPL3L are linked with childhood cardiomyopathy and age-related atrial fibrillation. However, the function served by this protein, a paralogue of the ubiquitously expressed RPL3 protein, remains poorly characterized in both heart and skeletal muscle. To address this, null mutant mice with the Rpl3L gene deleted were generated and studied. more...

(Submitter supplied) Although several ribosomal protein (RP) paralogs are expressed in a tissue-specific manner, how these proteins affect translation and why they are required only in certain tissues have remained unclear. Here we show that RPL3L, a paralog of RPL3 specifically expressed in heart and skeletal muscle, influences translation elongation dynamics. Deficiency of RPL3L-containing ribosomes (RPL3L-ribosomes) in RPL3L knockout male mice resulted in impaired cardiac contractility. more...

Analysis of right and left plantaris muscle from young males (5 months old) subjected to 1, 3, 5, 7, 10 and 14 days of synergist ablation surgery to induce hypertrophy. Results provide insight into the molecular response of young skeletal muscle to mechanical overload induced by synergist ablation.

(Submitter supplied) Failure of molecular chaperones to direct the correct folding of newly synthesized proteins leads to the accumulation of misfolded proteins in cells. HSPA4 is a member of the heat shock protein 110 family (HSP110) that acts as a nucleotide exchange factor of HSP70 chaperones. We found that the expression of HSPA4 is upregulated in murine hearts subjected to pressure overload and in failing human hearts. more...

(Submitter supplied) The expression of the small molecular weight heat shock protein (Hsp) H11 kinase/Hsp22 (Hsp22) is restricted to a limited number of tissues, including the heart and skeletal muscle, both in rodents and in humans. We generated a mouse knockout (KO) model, and investigated the role of Hsp22 in regulating cardiac hypertrophy in response to pressure overload. We compared gene expression profiles between WT and KO mice in basal condition and three days pressure overload after transverse aortic constriction (TAC). more...

(Submitter supplied) Methylation is a common post-translational modification that occurs primarily on lysine and arginine, but also on some other residues, such as histidine. METTL18 is the last uncharacterized member of a group of human methyltransferases (MTases) that mainly exert lysine methylation, and here we set out to elucidate its function. We found METTL18 to be a nuclear protein that contains a functional nuclear localization signal and accumulates in nucleoli. more...

(Submitter supplied) Pressure overload (PO) leads first to cardiac hypertrophy and later to heart failure. In mice, PO leads to sex differences in cardiac morphology and function. However, early sex differences in gene regulation that precede sex differences in function have not yet been identified. To identify such changes, we developed a model of PO that is characterized by compensated hypertrophy without sex differences after 2 weeks and by heart failure with sex differences after 9 weeks. more...

(Submitter supplied) An important event in the pathogenesis of heart failure is the development of pathological cardiac hypertrophy. In cultured cardiac cardiomyocytes, the transcription factor Gata4 is required for agonist-induced cardiomyocyte hypertrophy. We hypothesized that in the intact organism Gata4 is an important regulator of postnatal heart function and of the hypertrophic response of the heart to pathological stress. more...
