Integrated analysis of lncRNA and mRNA expression profiles in the submandibular glands of DIO mice

ABSTRACT: Objective: Obesity contributes to the dysfunction of salivary gland. To explore the specific underlying mechanism for obesity-induced hyposalivation, a model for high-fat diet-induced obese (DIO) mice were constructed to analyze long non-coding RNAs (lncRNAs) and messenger RNAs (mRNAs) expression profiles. Methods: The DIO group and control group were fed a diet containing 60 kcal% fat and a normal chow diet for 16 weeks respectively. Microarray analyses were performed to detect the expression profiles of lncRNA and mRNA in submandibular gland tissues from control group mice and DIO mice. Gene ontology, kyoto encyclopedia of genes and genomes, protein-protein interaction, coding-non-coding gene co-expression, transcription factors and competing endogenous RNA analyses were performed to examine the function of differential expressed genes. Results: The microarray identified that 624 lncRNAs, along with 297 mRNAs were differentially expressed. Bioinformatic analyses revealed that “complement and coagulation cascades”, “glutathione metabolism”, “cysteine and methionine metabolism”, and “estrogen signaling pathway” were significantly associated with candidate lncRNAs, transcription factors analysis on candidate lncRNAs reveled several genes such as tribbles pseudokinase 3 may play regulatory roles. Conclusions: Our results revealed the expression profiles of lncRNAs and mRNAs and provided new insights into the mechanism of obesity-induced hyposalivation using bioinformatic analyses.

A MAFG-lncRNA axis links systemic nutrient abundance to hepatic glucose metabolism: RNA profiles of metabolically active tissues.

Project description:Obesity and type 2 diabetes mellitus are global emergencies and long noncoding RNAs (lncRNAs) are regulatory transcrips with elusive functions in metabolism. Here we report that an unexpectedly high fraction of lncRNAs, but not protein-coding mRNAs, is repressed during diet-induced obesity (DIO) and refeeding, whilst nutrient deprivation specifically induced lncRNAs in mouse liver. Similarly, lncRNAs were lost in diabetic humans. LncRNA promoter analyses, global cistrome and gain-of-function analyses confirmed that increased MAFG signaling during DIO curbs lncRNA expression. Silencing Mafg in primary hepatocytes and in vivo elicited a fasting-like expression profile, improved glucose metabolism, derepressed lncRNAs and prevented mammalian target of rapamycin (mTOR)-driven protein translation. We found that obesity-repressed lincIRS2 is controlled by MAFG and observed that genetic and RNAi-mediated lincIRS2 loss causes hyperglycemia, insulin resistance and aberrant glucose output in lean mice. Taken together, we identify a novel MAFG-lncRNA axis controlling hepatic glucose metabolism in health and metabolic disease.

Activation of thermogenesis pathways in testis of diet-induced obesity mice

Project description:High-fat diet (HFD) induced obesity (DIO) has been shown impacts on metabolism, hormonal profile, male fertility, and spermatogenesis. We employed genome-wide transcriptional analysis on the testis of diet induced obesity (DIO) and normal chow (NC) C57BL/6 J male mice to search genes regulated by obesity in testis. Both blood glucose and lipids contents significantly increased in DIO mice after 8 weeks fat-rich feeding. RNA-seq analysis revealed 371 down-regulated and 460 up-regulated transcripts in DIO group comparing to NC group. Chromosome 3, 4, 9, 16, and 18 were significantly more active, while chromosome 5, 10, and 19 were significantly more inactive after 8-week fat-diet feeding. Wilcoxon enrichment analysis discovered that the thermogenesis pathway (KEGG) was significantly enriched in the testis of DIO group (with 8 enriched up-regulated genes: Smarca2, Adcy3, Atp5pb, Creb1, Gnas, Rps6kb2, Upcrc1 and Dpf1). Real-time PCR further confirmed that Smarca2 and Atp5pb were upregulated in the testis of DIO mice. These finding implied that diet-induced thermogenesis pathways could be altered in the testis of DIO mice.

Expression data from induced pluripotent stem cell-derived endothelial cells from healthy and diet-induced obesity mice

Project description:Little is known about the function of induced pluripotent stem cell-derived endothelial cells (iPSC-ECs) generated from diabetics, as this could potentially limit subsequent therapeutic use in this patient population. Here, we demonstrate that iPSC-ECs derived from diet-induced obesity (DIO) mice exhibit evidence of endothelial dysfunction. We also observed that mice receiving intramuscular (IM) injections of DIO iPSC-ECs had significantly decreased reperfusion following hindlimb ischemia compared to mice administered with iPSC-ECs from control mice. Hindlimb sections revealed increased muscle atrophy and presence of inflammatory cells in mice receiving iPSC-ECs from DIO mice. When pravastatin was administered to mice receiving DIO iPSC-ECs, a significant increase in reperfusion was observed, which was blunted by co-administration of L-NAME. This study is the first to provide evidence that iPSC-ECs from pre-diabetic mice exhibit signs of endothelial function, and suggest that pravastatin administration may be needed for diabetic patients receiving autologous iPSC-ECs therapy in the clinic. Four samples were analyzed, two from the healthy (control) group and two from the diet-induced obesity group

Genome-wide analysis of long noncoding RNA and messager RNA expression in ApoE-deficient mice

Project description:Atherosclerosis is a multifactorial chronic inflammatory disease with high prevalence and has become the first reason for death worldwide. Long non-coding RNAs (lncRNAs) are non-coding RNAs with a length of >200 bp. LncRNAs participate in many biological and pathological processes such as carcinogenesis, cardiovascular diseases. The present study was designed to investigate the lncRNA and mRNA expression in the aorta of diet-induced ApoE(-/-) mice using microarray analysis. The homozygous male apoE(-/-) mice were randomly divided into two groups, with 3 animals for each group. The normal diet group was fed with normal chow, while the treated group was fed with a high-fat, high-cholesterol diet containing 20% fat and 2.5% cholesterol. The treatment duration is 8-week. After treatment, the aorta of each mouse was taken, and the lncRNA and mRNAs profiles were detected using Agilent mouse lncRNA Microarray (4*180K, Design ID: 049801) which contains 51302 lncRNAs and 39430 mRNAs. As a result, a total of 354 differentially expressed lncRNAs, including 168 up-regulated and 186 down-regulated, were identified (≥2.0 folds). Simultaneously, we also identified 357 differentially expressed protein coding mRNAs from the same chip, including 211 up-regulated 146 down-regulated mRNAs. The present study identified a panel of dysregulated lncRNAs and mRNAs that may be potential biomarkers or drug targets and correlated with the pathogenesis of atherosclerosis.
