Cardiac hypertrophy and failure are accompanied by a reprogramming of gene expression that involves transcription factors and chromatin remodeling enzymes. Little is known about the roles of histone methylation and demethylation in this process. To understand the role of JMJD2A, a histone trimethyl demethylase, in cardiac hypertrophy, we generated mouse lines with heart-specific Jmjd2a deletion...
The response of cardiomyocytes to biomechanical stress can determine the pathophysiology of hypertrophic cardiac disease, and targeting the pathways regulating these responses is a therapeutic goal. However, little is known about how biomechanical stress is sensed by the cardiomyocyte sarcomere to transduce intracellular hypertrophic signals or how the dysfunction of these pathways may lead to ...
Background—Although -adrenergic receptor (AR) blockade therapy is beneficial in the treatment of heart failure, little is known regarding the transcriptional mechanisms underlying this salutary action. Methods and Results—In the present study, we screened mice overexpressing Gs , 1AR, 2AR, or protein kinase A to test if a common genomic pathway exists in different models with enhanced -adrenerg...
BACKGROUND Although beta-adrenergic receptor (AR) blockade therapy is beneficial in the treatment of heart failure, little is known regarding the transcriptional mechanisms underlying this salutary action. METHODS AND RESULTS In the present study, we screened mice overexpressing Gsalpha, beta1AR, beta2AR, or protein kinase A to test if a common genomic pathway exists in different models with ...
Four and a half LIM domain protein 1 (FHL1) was initially described as an abundant skeletal muscle protein with four LIM domains and a GATA like zinc finger. FHL1 was shown to be expressed in skeletal muscle as well as in a variety of other tissues. Recently, alternatively spliced FHL1 mRNAs were identified coding for C-terminal truncated proteins. The tissue distribution of these variants is m...
In yeast, ribosome production is controlled transcriptionally by tight coregulation of the 138 ribosomal protein genes (RPGs). RPG promoters display limited sequence homology, and the molecular basis for their coregulation remains largely unknown. Here we identify two prevalent RPG promoter types, both characterized by upstream binding of the general transcription factor (TF) Rap1 followed by t...
Four and a half LIM domains protein 1 (FHL1) and FHL2, as the name suggests, contain four and a half LIM domain binding proteins. Proteins in this family capable of interacting with many types of proteins, including structural proteins, kinases, and several classes of transcription factors, have been identified. These interactions have been found to have important roles in a variety of fundamen...
We recently identified the X-chromosomal four and a half LIM domain gene FHL1 as the causative gene for reducing body myopathy, a disorder characterized by progressive weakness and intracytoplasmic aggregates in muscle that exert reducing activity on menadione nitro-blue-tetrazolium (NBT). The mutations detected in FHL1 affected highly conserved zinc coordinating residues within the second LIM ...
Monomeric actin regulates gene expression through serum response factor (SRF) by inhibiting its transcriptional coactivator myocardin-related transcription factor (MAL/MRTF). Many affected genes encode cytoskeletal components. We have analysed the migratory effects of actin-MAL signalling and of new target genes in non-invasive highly adherent cells. Expression of active MAL impaired migration ...
