Project description:Diabetes leads to cardiomyopathy and heart failure, the leading cause of death for diabetic patients. Monoamine oxidase (MAO)-dependent reactive oxygen species (ROS) formation contributes to the development of diabetic cardiomyopathy by inducing mitochondrial and cardiomyocyte dysfunction. Yet, it is unclear whether, in addition to the direct effects exerted by MAO-dependent ROS on mitochondria, MAO activity is able to post-transcriptionally regulate cardiomyocyte function and survival in diabetes. To this aim, we performed gene and miRNA expression profiling in cardiac tissue from a mouse model of type 1 diabetes (T1D) with or without pharmacological MAO inhibition. We found that MAO-dependent ROS generation in T1D hearts leads to profound transcriptomic changes, affecting autophagy and pro-survival pathways activation. MAO activity in T1D hearts affected expression levels of miR-133a-3p, -193a-3p, and -27a-3p that target insulin-like growth factor receptor 1 (Igf1r), growth factor receptor bound protein 10 and inositol polyphosphate 4 phosphatase type 1A, respectively, all components of the Igf1r/PI3K/Akt signaling pathway. Indeed, Akt activation was significantly downregulated in T1D hearts, whereas MAO inhibition restored the activation of this pro-survival pathway. The present study provides an important link between MAO activity, transcriptomic changes, and activation of pro-survival signaling and autophagy in diabetic cardiomyopathy.

Project description:Here we used functional proteomics approaches to identify an upstream transcription complex (USTC) that is required for piRNA biogenesis. The complex contains PRDE-1, SNPC-4, TOFU-4, and TOFU-5, all of which are enriched on the two piRNA clusters on chromosome IV and form distinct piRNA foci in the nucleus.

Project description:Catecholamine metabolism via monoamine oxidase (MAO) contributes to cardiac injury in models of ischemia and diabetes, but the pathogenic mechanisms involved are unclear. MAO deaminates norepinephrine (NE) and dopamine (DA) to produce H2O2 and highly reactive ‘catecholaldehydes,’ which may be toxic to mitochondria due to the localization of MAO to the outer mitochondrial membrane. We performed a comprehensive analysis of catecholamine metabolism and its impact on mitochondrial energetics in atrial myocardium obtained from patients with and without type 2 diabetes. This data set contains a list of human cardiac mitochondrial proteins that were isolated following aminophenylboronic acid (APBA) column chromatography, which allows for selective purification of catechol-modified proteins. Samples of human heart mitochondria were prepared from discarded atrial appendage biopsies taken during elective cardiac surgery. Following extraction via APBA, bands were excised from a gel and subjected to proteomics analysis.

Project description:The effects of freeze-dried tofu, a traditional Japanese soy food, were compared with those of major active soy components, protein and isoflavone, by observing physiological differences and global transcriptomes in the liver of male rats. The GeneChip data was normalized and summarized by using SuperNORM data service (Skylight Biotech Inc.). Significance of expressional change among groups was tested by 2-way ANOVA on the normalized CEL data, which was deposited in a tab-separated ASCII text format. Principal components were identified on the summarized gene data. Rats were randomly divided into 6 groups of 5 samples and assigned experimental diets for 14 days. The experimental diets were as follows: casein diet (C); C containing isoflavone (CI) soy protein diet (S); S containing isoflavone (SI); a diet containing 100 g/kg each of protein derived from casein and freeze-dried tofu (T10); a diet containing 200 g/kg of protein derived from freeze-dried tofu (T20). CI and SI were supplemented with a mixture of isoflavones to match the isoflavone level of T20.

Project description:Soybean and fish contains various active components that were reported to prevent cardiovasucular diseases. Epidemiological studies indicated that Asian eating patterns, consisting of daily seafood and/or soy consumption, confer protection against cardiovascular diseases. In this context, we expected that simultaneous intake of soybean and fish may be greatly beneficial in a manner different from the ingestion of the individual food. To understand the detailed mechanism for modulating the lipid metabolism by co-ingestion of a soy food (tofu) and fish oil, we investigated the global changes in hepatic mRNA expression in rats by using a microarray analysis. Generally, ingestion of tofu contributed to prevent the mRNA expressions involved in hepatic lipogenesis, whereas fish oil facilitated the mRNA expressions related to the degradation of hepatic fatty acids. In terms of mRNA expression, the interaction of two dietary factors was limited. The expression data was normalized and summarized by using SuperNORM data service (Skylight Biotech Inc.). Significance of expressional change among groups was tested by 2-way ANOVA on the normalized CEL data, which was deposited in a tab-separated ASCII text format. Principal components were identified on the summarized gene data. Rats were divided into four groups each with similar average body weights and assigned experimental diets for 21 days as follows: casein and soybean oil diet (CS); casein and fish oil diet (CF); tofu and soybean oil diet (TS); tofu and fish oil diet (TF). Total protein and fat content of each diet was 200 and 150 g/kg, respectively. Soybean oil diets (CS and TS) contain 150 g/kg diet of soybean-derived fat (i.e. soybean oil and freeze-dried tofu), and 50 g/kg of fish oil was replaced with the same amount of soybean-derived fat for fish oil diets (CF and TF). Animals were allowed free access to food and water.

Project description:Piwi-interacting RNAs (piRNAs) play significant roles in suppressing transposons and nonself nucleic acids, maintaining genome integrity, and defending against viral infections, and are essential for fertility in a variety of organisms. In C. elegans, most piRNA precursors are transcribed by RNA polymerase II in the nucleus and are subjected to a number of processing and maturation steps. However, the biogenesis of piRNAs is still not fully understood. We used functional proteomics to study piRNA biogenesis in C. elegans and identified a piRNA processing and chromosome segregation (PICS) complex. The PICS complex contains two known piRNA biogenesis factors, TOFU-6 and PID-1, and three new proteins PICS-1, TOST-1, and ERH-2, which exhibit dynamic localization among different subcellular compartments. In the germlines of gravid animals, the PICS complex contains TOFU-6/PICS-1/ERH-2/PID-1, is largely concentrated at the perinuclear granule zone and engages in piRNA processing. During early embryogenesis, the TOFU-6/PICS-1/ERH-2/TOST-1 complex accumulates in the nucleus and plays essential roles in chromosome segregation and cell division. Interestingly, the functions of these factors in mediating chromosome segregation are independent of piRNA production. Therefore, we speculate that differential compositions of PICS factors may help cells coordinate distinct cellular processes.

Project description:Obesity is associated with insulin resistance and increased intrahepatic triglyceride (IHTG) content, which are key risk factors for diabetes and cardiovascular disease. However, a subset of obese people does not develop these metabolic complications. We tested the hypothesis that MNO, but not MAO, people are protected from the adverse metabolic effects of weight gain. To this end, global transcriptional profile in adipose tissue before and after weight gain was evaluated by microarray analyses. We collected subcutaneous adipose tissue samples from MNO (n=11) and MAO (n=7) subjects before and after moderate (~6%) weight gain (total 36 samples). We evaluated the effects of weight gain on adipose tissue gene expression in both MNO and MNO subjects.We used the GeneChip Human Gene 1.0 ST array (Affymetrix, Santa Clara, CA, USA).
