View SamplesPressure overload induces a transition from cardiac hypertrophy to heart failure, but its underlying mechanisms remain elusive. Here we reconstruct a trajectory of cardiomyocyte remodeling and clarify distinct cardiomyocyte gene programs encoding morphological and functional signatures in cardiac hypertrophy and failure, by integrating single-cardiomyocyte transcriptome with cell morphology, epigenomic state and heart function. During early hypertrophy, cardiomyocytes activate mitochondrial translation/metabolism genes, whose expression is correlated with cell size and linked to ERK1/2 and NRF1/2 transcriptional networks. Persistent overload leads to a bifurcation into adaptive and failing cardiomyocytes, and p53 signaling is specifically activated in late hypertrophy. Cardiomyocyte-specific p53 deletion shows that cardiomyocyte remodeling is initiated by p53-independent mitochondrial activation and morphological hypertrophy, followed by p53-dependent mitochondrial inhibition, morphological elongation, and heart failure gene program activation. Human single-cardiomyocyte analysis validates the conservation of the pathogenic transcriptional signatures. Collectively, cardiomyocyte identity is encoded in transcriptional programs that orchestrate morphological and functional phenotypes. Overall design: Integrative analysis of single-cardiomyocyte RNA-seq of pressure-overload-induced heart failure model mice and heart failure patients with dilated cardiomyopathy, single-cell morphology, cardiac function and genetic perturbation

View SamplesMerm1/Wbscr22 is one of genes in chromosomal region deleted in Williams-Beuren syndrome, a multisystem developmental disorder. Wbscr22 contains a nuclear localization signal and an S-adenosyl-L-methionine-dependent methyltransferase fold, but its real function is completely unknown.In this study, to examine the function, we compared the gene expression profiles between control and Merm1/Wbscr22 knock-downed tumor cells.
The novel metastasis promoter Merm1/Wbscr22 enhances tumor cell survival in the vasculature by suppressing Zac1/p53-dependent apoptosis.

View SamplesThe accumulation of intramyocellular lipid (IMCL) is recognized as an important determinant of insulin resistance, and is increased by a high-fat diet (HFD). However, the effects of HFD on IMCL and insulin sensitivity are highly variable.
Increased intramyocellular lipid/impaired insulin sensitivity is associated with altered lipid metabolic genes in muscle of high responders to a high-fat diet.

View SamplesIn this study, we sought to establish the usefulness of LCM on cDNA microarray analysis. We reported that LCM samples improved the sensitivity of detection of differentially expressed genes over conventional bulk tissue analysis. We also provided the new information of chemokine and its receptor interaction within psoriatic lesional skin.

View SamplesMicroarray experiments were performed using Arabidopsis wild type plants (Col-0) and srk2cf double knockout mutants to investigate functions of two osmotic stress-activated protein kinases, SRK2C and SRK2F. Transcription profiles of wild type and mutants were compared under abscisic acid (ABA) treatment for 0, 1 and 4 h.
