Comparison of transcriptome landscape between adenine-induced and nephrectomy-induced uremic cardiomyopathy

Project description:Adenine and nephrectomy can be used to establish models of uremic cardiomyopathy in rodents. Although these two approaches cause similar phenotypes of heart, adenine may directly act on cardiomyocytes and lead to different molecular changes from nephrectomy-induced uremic cardiomyopathy. Transcriptome analysis on left ventricles showed 789 upregulated and 345 downregulated genes in mice with nephrectomy-induced uremic cardiomyopathy compared to control mice, while 432 upregulated and 155 downregulated genes in mice with adenine diet-induced uremic cardiomyopathy compared to control mice. Functional analysis revealed that these DEGs were involved in pathways related to immune inflammation, metabolic responses, and synaptic transmission. Further analysis demonstrated that nephrectomy-induced uremic cardiomyopathy has enhanced cell cycle process/extracellular matrix remodeling and suppressed fatty acid metabolism, whereas adenine diet-induced uremic cardiomyopathy only exhibits increased inflammatory response/extracellular matrix remodeling. Compared with nephrectomy-induced uremic cardiomyopathy, adenine diet-induced uremic cardiomyopathy showed improved oxidative phosphorylation, aerobic electron transport chain, and tricarboxylic acid cycle, and suppressed cell cycle-related process, indicating that adenine and its derivates may affect the process of chronic kidney induced cardiac changes.

Role of adipose tissue Na/K ATPase signaling in uremic cardiomyopathy

Project description:The objective of the present study is to explore the role of human MSC derived adipocytes transduced with/without lenti adipo-NaKtide or lenti adipo-scrambled NaKtide in experimental uremic cardiomyopathy. We investigated the pathophysiological changes in recipient mice that underwent partial nephrectomy surgery, as a model of uremic cardiomyopathy, and implanted with NaKtide transfected human MSC derived adipocytes. We aimed to demonstrate that adipocyte specific NaKtide reprograms the adipocyte phenotype and transplantation of these metabolically healthy adipocytes in diseased condition exhibits improved systemic and cardiovascular function, through intra-organ crosstalk.

Gene expression profiles in experimental uremic cardiomyopathy.

Project description:Purpose: To define differentially regulated pathways in heart tissue from mice with chornic kidney disease (CKD) compared to age-matched controls. Methods: CKD was induced in 5-week-old, male 129X1/SvJ mice (JAX) through five-sixths nephrectomy in a two-step surgery (n=5). Age-matched mice undergoing bilateral sham surgeries served as controls (n=5). Heart tissue was collected at 8 weeks of CKD for next generation sequencing. Results: Hearts from mice with uremic cardiomyopathy yielded over 1,000 differentially-expressed mRNA transcripts compared to hearts from age-matched, sham-operated mice. Ingenuity biofunctions analysis identified significant enrichment for genes involved in Tissue Morphology, Immune Cell Trafficking, Cardiovascular Development and Function, and Humoral Immune Response. We focused on Ingenuity canonical pathways involving inflammation and immune system function including pathways needed for a T-cell mediated response: leukocyte extravasation, antigen presentation, dendritic cell maturation, T cell co-stimulatory signaling, and T-helper cell differentiation. Conclusions: Left ventricles from mice with CKD display differential expression in a number of pathways suggesting inflammation and surprisingly involved genes involved in the adaptive immune system.

B-Receptor Signaling in Cardiomyopathy

Project description:We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.

Uremic pruritus patients serum DIA

Project description:Uremic pruritus (UP) is one of the common symptoms in patients with uremia, and its etiology and mechanism have not been fully understood. In view of the high incidence of UP, finding the specific changed proteins in blood of UP patients will help revealing the potential biological mechanisms of UP and explore biomarkers. In this study, LC-MS/MS based data independent acquisition (DIA) mode was used to analyze the serum samples of 54 UP patients (DKD-UP, HN-UP and GN-UP, n=18 for each), 18 uremic patients without pruritus (Negative) and 18 CKD patients without pruritus (CKD).

Identification of novel hyper- or hypo-methylated CpG sites and genes associated with anthracycline-induced cardiomyopathy

Project description:Genome wide DNA methylation profiling of peripheral blood DNA from childhood cancer survivors with and without anthracycline induced cardiomyopathy. DNA methylation status of 850,000 CpG sites was analyzed using the Illumina HumanMethylation EPIC BeadChip arrays. Matched case-control study (COG-ALTE03N1); 52 non-Hispanic White, anthracycline-exposed childhood cancer survivors with cardiomyopathy were matched 1:1 with 52 survivors with no cardiomyopathy. Anthracycline-induced cardiomyopathy is a leading cause of late morbidity in childhood cancers survivors. Aberrant DNA methylation plays a role in de novo cardiovascular disease. Epigenetic processes could play a role in anthracycline-induced cardiomyopathy, but remain unstudied. We sought to examine if genome-wide differential methylation at ‘CpG’ sites in peripheral blood DNA is associated with anthracycline-induced cardiomyopathy. We observed significant differences in DNA methylation between anthracycline-exposed childhood cancer survivors with and without cardiomyopathy, implicating differential DNA methylation in anthracycline-induced cardiomyopathy.

Transcriptome analysis of adenine-treated murine microglial cells

Project description:In previous study, we demonstrated adenine-induced cell signaling on anti-inflammation in BV2 cells. To investigate the changes of transcriptome mediated by adenine, we used microarrays to compare the difference in expression levels.
