Abstract
BACKGROUND High doses of doxorubicin put cancer patients at risk for developing dilated cardiomyopathy. Previously, we showed that doxorubicin treatment decreases SIRT3 (sirtuin 3), the main mitochondrial deacetylase and increases protein acetylation in rat cardiomyocytes. Here, we hypothesize that SIRT3 expression can attenuate doxorubicin induced dilated cardiomyopathy in vivo by preventing the acetylation of mitochondrial proteins. METHODS Nontransgenic, M3-SIRT3 (truncated SIRT3; short isoform), and M1-SIRT3 (full-length SIRT3; mitochondrial localized) transgenic mice were treated with doxorubicin for 4 weeks (8 mg/kg body weight per week). Echocardiography was performed to assess cardiac structure and function and validated by immunohistochemistry and immunofluorescence (n=4-10). Mass spectrometry was performed on cardiac mitochondrial peptides in saline (n=6) and doxorubicin (n=5) treated hearts. Validation was performed in doxorubicin treated primary rat and human induced stem cell derived cardiomyocytes transduced with adenoviruses for M3-SIRT3 and M1-SIRT3 and deacetylase deficient mutants (n=4-10). RESULTS Echocardiography revealed that M3-SIRT3 transgenic mice were partially resistant to doxorubicin induced changes to cardiac structure and function whereas M1-SIRT3 expression prevented cardiac remodeling and dysfunction. In doxorubicin hearts, 37 unique acetylation sites on mitochondrial proteins were altered. Pathway analysis revealed these proteins are involved in energy production, fatty acid metabolism, and oxidative stress resistance. Increased M1-SIRT3 expression in primary rat and human cardiomyocytes attenuated doxorubicin-induced superoxide formation, whereas deacetylase deficient mutants were unable to prevent oxidative stress. CONCLUSIONS Doxorubicin reduced SIRT3 expression and markedly affected the cardiac mitochondrial acetylome. Increased M1-SIRT3 expression in vivo prevented doxorubicin-induced cardiac dysfunction, suggesting that SIRT3 could be a potential therapeutic target for mitigating doxorubicin-induced dilated cardiomyopathy.

Abstract
Through unknown mechanisms, fetal exposure to gestational diabetes mellitus (GDM) increases the risk for cardiovascular disease development later in life. We hypothesize that fetal exposure to GDM alters offspring cardiomyocyte metabolism and left ventricular (LV) function with age. To induce GDM, female rats were fed a high fat (45% kcal) and sucrose diet prior to mating, throughout pregnancy and lactation. Lean controls received a low fat (10% kcal) diet. Fetal rat ventricular cardiomyocytes (FRVC) were isolated from e20 offspring for U-13C glucose metabolic flux analysis, mitochondrial respiration and calcium handling. The cardiac transcriptome and metabolome were measured in 3-month old offspring. LV morphology and function was assessed in the offspring from e18 to 12-months of age by transthoracic ultrasound. Offspring exposed to GDM exhibited increased LV posterior wall thickness and impaired LV filling across their life course (fetal to 12-months of age; p<0.05). Consistent with the development of diastolic dysfunction in vivo, alterations in calcium flux and sarcoplasmic reticulum-dependent calcium re-uptake (1.5 and 1.6-fold greater, respectively) were observed in FRVC isolated from GDM offspring (p<0.05). When FRVC were treated with isoproterenol, U-13C glucose metabolic flux through glycolysis and the citric acid cycle was reduced in GDM offspring, compared to Lean controls. In 3-month old GDM offspring serum and cardiac metabolomics revealed an altered acylcarnitine profile, with specific elevation in long chain acylcarnitine species including stearoylcarnitine. Alterations in the metabolome corresponded to changes in gene expression patterns identified by RNA-Seq associated with glucose metabolism and fatty acid transport pathways (e.g.
Irs2, Slc2a4, Pfkfb2, Pdk4
and
Cpt1a).
These alterations corresponded with mitochondrial dysfunction, impaired cardiomyocyte metabolic flux and contractility, in concert with LV hypertrophy and diastolic dysfunction in the rat offspring. Multi-omics profiling reveals stearoylcarnitine as a novel biomarker and implicates mitochondrial oxidative metabolism as a mechanism that links early-life GDM exposure to the development of cardiovascular disease later in life.

Abstract
Lipotoxicity is a form of cellular stress caused by the accumulation of lipids resulting in mitochondrial dysfunction and insulin resistance in muscle. Previously, we demonstrated that the mitophagy receptor BNIP3L/Nix is responsive to lipotoxicity and accumulates in response to a high-fat (HF) feeding. To provide a better understanding of this observation, we undertook gene expression array and shot-gun metabolomics studies in soleus muscle from rodents on an HF diet. Interestingly, we observed a modest reduction in several autophagy-related genes. Moreover, we observed alterations in the fatty acyl composition of cardiolipins and phosphatidic acids. Given the reported roles of these phospholipids and BNIP3L in mitochondrial dynamics, we investigated aberrant mitochondrial turnover as a mechanism of impaired myocyte insulin signaling. In a series of gain-of-function and loss-of-function experiments in rodent and human myotubes, we demonstrate that BNIP3L accumulation triggers mitochondrial depolarization, calcium-dependent activation of DNM1L/DRP1, and mitophagy. In addition, BNIP3L can inhibit insulin signaling through activation of MTOR-RPS6KB/p70S6 kinase inhibition of IRS1, which is contingent on phosphatidic acids and RHEB. Finally, we demonstrate that BNIP3L-induced mitophagy and impaired glucose uptake can be reversed by direct phosphorylation of BNIP3L by PRKA/PKA, leading to the translocation of BNIP3L from the mitochondria and sarcoplasmic reticulum to the cytosol. These findings provide insight into the role of BNIP3L, mitochondrial turnover, and impaired myocyte insulin signaling during an overfed state when overall autophagy-related gene expression is reduced. Furthermore, our data suggest a mechanism by which exercise or pharmacological activation of PRKA may overcome myocyte insulin resistance.

Abstract
Fetal exposure to gestational diabetes mellitus (GDM) and poor postnatal diet are strong risk factors for type 2 diabetes development later in life, but the mechanisms connecting GDM exposure to offspring metabolic health remains unclear. In this study, we aimed to determine how GDM interacts with the postnatal diet to affect islet function in the offspring as well as characterize the gene expression changes in the islets. GDM was induced in female rats using a high-fat, high-sucrose (HFS) diet, and litters from lean or GDM dams were weaned onto a low-fat (LF) or HFS diet. Compared with the lean control offspring, GDM exposure reduced glucose-stimulated insulin secretion in islets isolated from 15-week-old offspring, which was additively worsened when GDM exposure was combined with postnatal HFS diet consumption. In the HFS diet-fed offspring of lean dams, islet size and number increased, an adaptation that was not observed in the HFS diet-fed offspring of GDM dams. Islet gene expression in the offspring of GDM dams was altered in such categories as inflammation (e.g., Il1b, Ccl2), mitochondrial function/oxidative stress resistance (e.g., Atp5f1, Sod2), and ribosomal proteins (e.g., Rps6, Rps14). These results demonstrate that GDM exposure induced marked changes in gene expression in the male young adult rat offspring that cumulatively interact to worsen islet function, whole-body glucose homeostasis, and adaptations to HFS diets.

Abstract
KEY POINTS Maternal resveratrol (RESV) administration in gestational diabetes (GDM) restored normoglycaemia and insulin secretion. GDM-induced obesity was prevented in male GDM+RESV offspring but not in females. GDM+RESV offspring exhibited improved glucose tolerance and insulin sensitivity. GDM+RESV restored hepatic glucose homeostasis in offspring. Glucose-stimulated insulin secretion was enhanced in GDM+RESV offspring. ABSTRACT Gestational diabetes (GDM), the most common complication of pregnancy, is associated with adverse metabolic health outcomes in offspring. Using a rat model of diet-induced GDM, we investigated whether maternal resveratrol (RESV) supplementation (147 mg kg-1 day-1 ) in the third week of pregnancy could improve maternal glycaemia and protect the offspring from developing metabolic dysfunction. Female Sprague-Dawley rats consumed a high-fat and sucrose (HFS) diet to induce GDM. Lean controls consumed a low-fat (LF) diet. In the third trimester, when maternal hyperglycaemia was observed, the HFS diet was supplemented with RESV. At weaning, offspring were randomly assigned a LF or HFS diet until 15 weeks of age. In pregnant dams, RESV restored glucose tolerance, normoglycaemia and improved insulin secretion. At 15 weeks of age, GDM+RESV-HFS male offspring were less obese than the GDM-HFS offspring. By contrast, the female GDM+RESV-HFS offspring were similarly as obese as the GDM-HFS group. Hepatic steatosis, insulin resistance, glucose intolerance and dysregulated gluconeogenesis were observed in the male GDM offspring and were attenuated in the offspring of GDM+RESV dams. The dysregulation of several metabolic genes (e.g. ppara, lpl, pepck and g6p) in the livers of GDM offspring was attenuated in the GDM+RESV offspring group. Glucose stimulated insulin secretion was also improved in the islets from offspring of GDM+RESV dams. Thus, maternal RESV supplementation during the third trimester of pregnancy and lactation induced several beneficial metabolic health outcomes for both mothers and offspring. Therefore, RESV could be an alternative to current GDM treatments.

Abstract
Background Birth cohort studies link gestational diabetes mellitus (GDM) with impaired cognitive performance in the offspring. However, the mechanisms involved are unknown. We tested the hypothesis that obesity-associated GDM induces chronic neuroinflammation and disturbs the development of neuronal circuitry resulting in impaired cognitive abilities in the offspring. Methods In rats, GDM was induced by feeding dams a diet high in sucrose and fatty acids. Brains of neonatal (E20) and young adult (15-week-old) offspring of GDM and lean dams were analyzed by immunohistochemistry, cytokine assay, and western blotting. Young adult offspring of GDM and lean dams went also through cognitive assessment. Cultured microglial responses to elevated glucose and/or fatty acids levels were analyzed. Results In rats, impaired recognition memory was observed in the offspring of GDM dams. GDM exposure combined with a postnatal high-fat and sucrose diet resulted in atypical inattentive behavior in the offspring. These cognitive changes correlated with reduced density and derangement of Cornu Ammonis 1 pyramidal neuronal layer, decreased hippocampal synaptic integrity, increased neuroinflammatory status, and reduced expression of CX3CR1, the microglial fractalkine receptor regulating microglial pro-inflammatory responses and synaptic pruning. Primary microglial cultures that were exposed to high concentrations of glucose and/or palmitate were transformed into an activated, amoeboid morphology with increased nitric oxide and superoxide production, and altered their cytokine release profile. Conclusions These findings demonstrate that GDM stimulates microglial activation and chronic inflammatory responses in the brain of the offspring that persist into young adulthood. Reactive gliosis correlates positively with hippocampal synaptic decline and cognitive impairments. The elevated pro-inflammatory cytokine expression at the critical period of hippocampal synaptic maturation suggests that neuroinflammation might drive the synaptic and cognitive decline in the offspring of GDM dams. The importance of microglia in this process is supported by the reduced Cx3CR1 expression as an indication of the loss of microglial control of inflammatory responses and phagocytosis and synaptic pruning in GDM offspring.

Abstract
The incidence of obesity and type 2 diabetes mellitus have risen across the world during the past few decades and has also reached an alarming level among children. In addition, women are currently more likely than ever to enter pregnancy obese. As a result, the incidence of gestational diabetes mellitus is also on the rise. While diet and lifestyle contribute to these trends, population health data show that maternal obesity and diabetes during pregnancy during critical stages of development are major factors that contribute to the development of chronic disease in adolescent and adult offspring. Fetal programming of metabolic function, through physiological and (or) epigenetic mechanisms, may also have an intergenerational effect, and as a result may perpetuate metabolic disorders in the next generation. In this review, we summarize the existing literature that characterizes how maternal obesity and gestational diabetes mellitus contribute to metabolic and cardiovascular disorders in the offspring. In particular, we focus on animal studies that investigate the molecular mechanisms that are programmed by the gestational environment and lead to disease phenotypes in the offspring. We also review interventional studies that prevent disease with a developmental origin in the offspring.
