Human MCF7 cells: Mock control vs. siRNA transfected against calreticulin

Project description:Transcriptional profiling of human MCF7 cells comparing mock control MCF7cells with MCF7cells transfected by siRNA against calreticulin. The latter was shown to be of having significantly decreased expression of calreticulin followed by significant decrease in migrative and invasive potentials of the MCF7 cells. Goal was to determine the effect of calreticulin knockdown on the global gene expression of MCF7 cells. Two-condition experiment, Mock control MCF7 cells vs. calreticulin siRNA knockdown MCF7 cells. Biological replicates: 3 mock control replicates, 3 transfected replicates.

KDM8 epigenetically controls cardiac metabolism to prevent initiation of dilated cardiomyopathy [CUT&Tag]

Project description:Cardiac metabolism is deranged in heart failure, but underlying mechanisms remain unclear. Lysine demethylase 8 (Kdm8) represses gene expression in the embryo and controls metabolism in cancer. However, its function in cardiac homeostasis is unknown. We show that Kdm8 maintains a mitochondrial gene network active by repressing Tbx15 to prevent dilated cardiomyopathy leading to lethal heart failure. Deletion of Kdm8 in mouse cardiomyocytes increased H3K36me2 with activation of Tbx15 and repression of target genes in the NAD+ pathway before dilated cardiomyopathy initiates. Moreover, NAD+ supplementation prevented dilated cardiomyopathy in Kdm8 mutant mice and TBX15 overexpression blunted NAD+-activated cardiomyocyte respiration. Furthermore, KDM8 was downregulated in human hearts affected by dilated cardiomyopathy and higher TBX15 expression defines a subgroup of affected hearts with the strongest downregulation of genes encoding mitochondrial proteins. Thus, KDM8 represses TBX15 to maintain cardiac metabolism. Our results suggest that epigenetic dysregulation of metabolic gene networks initiates myocardium deterioration towards heart failure and could underlie heterogeneity of dilated cardiomyopathy.

Cardiac disruption of SDHAF4-mediated mitochondrial complex II assembly promotes dilated cardiomyopathy

Project description:Succinate dehydrogenase, which is known as mitochondrial complex II, has proven to be a fascinating machinery, attracting renewed and increased interest in its involvement in human diseases. Herein, we find that succinate dehydrogenase assembly factor 4 (SDHAF4) is downregulated in cardiac muscle in response to pathological stresses and in diseased hearts from human patients. Cardiac loss of Sdhaf4 suppresses complex II assembly and results in subunit degradation and complex II deficiency in fetal mice. These defects are exacerbated in young adults with globally impaired metabolic capacity and activation of dynamin-related protein 1, which induces excess mitochondrial fission and mitophagy, thereby causing progressive dilated cardiomyopathy and lethal heart failure in animals. Targeting mitochondria via supplementation with fumarate or inhibiting mitochondrial fission improves mitochondrial dynamics, partially restores cardiac function and prolongs the lifespan of mutant mice. Moreover, the addition of fumarate is found to dramatically improve cardiac function in myocardial infarction mice. These findings reveal a vital role for complex II assembly in the development of dilated cardiomyopathy and provide additional insights into therapeutic interventions for heart diseases.

Study the effect of calreticulin knockdown on genome-wide transcript expression in HepG2 cells

Project description:The objective was to evaluate the status of the global hepatic transcriptome in the presence of inhibited calreticulin levels. Results identify a total of 324 genes were altered of which 245 genes were downregulated and 79 genes were upregulated. This suggests that such altered genes might be associated with altered hepatic physiology that are observed during calreticulin deficiency. Total RNA was isolated from HepG2 cells subjected to calreticulin (CRT) siRNA for 24 hours compared to control HepG2 cells subjected to scramble siRNA for 24 hours. This was then hybridized to Illumina HumanHT-12 v4 Expression BeadChip arrays.

changes in cardiac transcription profiles brought about by heart failure

Project description:To establish changes in cardiac transcription profiles brought about by heart failure we collected myocardial samples from patients undergoing cardiac transplantation whose failure arises from different etiologies (e.g. idiopathic dilated cardiomyopathy, ischemic cardiomyopathy, alcoholic cardiomyopathy, valvular cardiomyopathy, and hypertrophic cardiomyopathy) and from "normal" organ donors whose hearts cannot be used for transplants. The transcriptional profile of the mRNA in these samples will be measured with gene array technology. Changes in transcriptional profiles can be correlated with the physiologic profile of heart-failure hearts acquired at the time of transplantation. Keywords: other
