Abstract
Microarray analysis reveals that the specific pattern of gene expression in cardiomyocytes derived from embryonic stem cells reflects the biological, physiological and functional processes occurring in mature cardiomyocytes. Background Characterization of gene expression signatures for cardiomyocytes derived from embryonic stem cells will help to define their early biologic processes. Results A transgenic α-myosin heavy chain (MHC) embryonic stem cell lineage was generated, exhibiting puromycin resistance and expressing enhanced green fluorescent protein (EGFP) under the control of the α-MHC promoter. A puromycin-resistant, EGFP-positive, α-MHC-positive cardiomyocyte population was isolated with over 92% purity. RNA was isolated after electrophysiological characterization of the cardiomyocytes. Comprehensive transcriptome analysis of α-MHC-positive cardiomyocytes in comparison with undifferentiated α-MHC embryonic stem cells and the control population from 15-day-old embryoid bodies led to identification of 884 upregulated probe sets and 951 downregulated probe sets in α-MHC-positive cardiomyocytes. A subset of upregulated genes encodes cytoskeletal and voltage-dependent channel proteins, and proteins that participate in aerobic energy metabolism. Interestingly, mitosis, apoptosis, and Wnt signaling-associated genes were downregulated in the cardiomyocytes. In contrast, annotations for genes upregulated in the α-MHC-positive cardiomyocytes are enriched for the following Gene Ontology (GO) categories: enzyme-linked receptor protein signaling pathway (GO:0007167), protein kinase activity (GO:0004672), negative regulation of Wnt receptor signaling pathway (GO:0030178), and regulation of cell size (O:0008361). They were also enriched for the Biocarta p38 mitogen-activated protein kinase signaling pathway and Kyoto Encyclopedia of Genes and Genomes (KEGG) calcium signaling pathway. Conclusion The specific pattern of gene expression in the cardiomyocytes derived from embryonic stem cells reflects the biologic, physiologic, and functional processes that take place in mature cardiomyocytes. Identification of cardiomyocyte-specific gene expression patterns and signaling pathways will contribute toward elucidating their roles in intact cardiac function.

A change of expression in the conserved signaling gene MKK7 is associated with a selective sweep in the western house mouse Mus musculus domesticus. J Evol Biol 2006; 19:1486-96.

Abstract
Changes in gene expression are known to occur between closely related species, but it is not yet clear how many of these are due to random fixation of allelic variants or due to adaptive events. In a microarray survey between subspecies of the Mus musculus complex, we identified the mitogen-activated protein-kinase-kinase MKK7 as a candidate for change in gene expression. Quantitative PCR experiments with multiple individuals from each subspecies confirmed a specific and significant up-regulation in the testis of M. m. domesticus. Northern blot analysis shows that this is due to a new transcript that is not found in other tissues, nor in M. m. musculus. A cis-trans test via allele specific expression analysis of the MKK7 gene in F1 hybrids between domesticus and musculus shows that the expression change is mainly caused by a mutation located in cis. Nucleotide diversity was found to be significantly reduced in a window of at least 20 kb around the MKK7 locus in domesticus, indicative of a selective sweep. Because the MKK7 gene is involved in modulating a kinase signalling cascade in a stress response pathway, it seems a plausible target for adaptive differences between subspecies, although the functional role of the new testis-specific transcripts will need to be further studied.
