Project description:Diabetic macroangiopathy is one of the most common serious complications of diabetes. Previous studies indicate that lncRNAs involved in the process of diabetes and another vascular disease. However, their detailed mechanism of the lncRNAs involved in diabetic macroangiopathy has not been well characterized. In the present study, we generated rat models of diabetic macroangiopathy induced by High fat. A total of 15 GK rats was constructed as a test group, along with 15 Wistar rats set as a control group, and thoracic aorta tissue from each group was collected. Whole genomic RNA sequencing was performed on thoracic aorta tissue;3223 novel lncRNAs and 20367 annotated lncRNAs were identified in thoracic aorta samples, and 864 lncRNAs were expressed differently in the test and control groups. Gene ontology term enrichment showed the apparent enrichment of inflammatory response and cell apoptosis, which consistent with the results of H&E Staining, TUNEL Assay, and ELISA; Extensive literature reveals inflammatory response and cell apoptosis play an important role in the process of diabetic macroangiopathy.The results of the present study indicated that lncRNAs, especiallyNrep.bSep08,Col5a1,aSep0,soygee.aSep08-unspliced,NONRATT013247.2,votar.aSep08-unspliced,etc,both participate in and mediate the process of inflammatory response,cell apoptosis.What’s more, Our research provides further insights into the understanding of the basic molecular mechanisms underlying diabetic macroangiopathy.

Project description:The aim of this study is to compare renal transcriptome profiling between diabetic nephropathy (DN) and DN treated with human placenta-derived mesenchymal stem cells (PMSCs) groups. Twelve renal cortex samples (n=6 for each DN and treatment group) were sequenced using Illumina Hiseq 4000. We identified 90 differentially expressed genes between DN and treatment griups with |og2 FoldChange| ≥1 and p value <0.05. Our study represents the first detailed analysis of renal transcriptomes, with biologic replicates, generated by RNA-seq technology.

Project description:AIMS/HYPOTHESIS: Pregnancies complicated by diabetes have a higher risk of adverse outcomes for mothers and children, including predisposition to disease later in life, such as metabolic syndrome and hypertension. We hypothesized that adverse outcomes from diabetic pregnancies may be linked to compromised placental function. Our goal in this study was to identify cellular and molecular abnormalities in diabetic placenta. METHODS: Using a mouse model of diabetic pregnancy, placental gene expression was assayed at midgestation and cellular composition was analyzed at various stages. Genome-wide expression profiling was validated by quantitative PCR, and tissue localization studies were performed to identify cellular correlates of altered gene expression in diabetic placenta. RESULTS: We detected significantly altered gene expression in diabetic placenta for genes expressed in the maternal as well as those in the embryonic compartments. We also found altered cellular composition of the decidual compartment. Furthermore, the junctional and labyrinth layers were reduced in diabetic placenta, accompanied by aberrant differentiation of spongiotrophoblast cells. CONCLUSIONS/INTERPRETATION: Diabetes during pregnancy alters transcriptional profiles in the murine placenta, affecting cells of both embryonic and maternal origin, and involving several genes not previously implicated in diabetic pregnancies. The molecular changes and abnormal differentiation of multiple cell types precede impaired growth of junctional zone and labyrinth, and placenta overall. Whether these changes represent direct responses to hyperglycaemia or physiological adaptations, they are likely to play a role in pregnancy complications and outcomes, and have implications for developmental origins of adult disease. The STZ diabetic mouse model was used to investigate gene expression changes in diabetic placentae at E10.5. Placentae were dissected from 5 different FVB dams at embryonic day 10.5 under diabetic conditions and from 5 control dams. Gene expression profiles from five individual placentae from independent pregnancies per group were compared.

Project description:Background: Long non-coding RNAs (lncRNAs) are an important class of pervasive genes involved in a variety of biological functions. They are aberrantly expressed in many types of diseases. We want to study the lncRNAs profiles in preeclampsia. Preeclampsia has been observed in patients with molar pregnancy where a fetus is absent demonstrating that the placenta is sufficient to cause the condition. So we analyze the lncRNAs profiles in preeclampsia placentas. In this study, we described the lncRNAs profiles in 6 preeclampsia placentas (T) and 5 matched normal pregnancy placentas (N) tissues by microarray. Methodology/Principal Findings: With abundant and varied probes accounting 33,045 LncRNAs in our microarray, the number of lncRNAs that expressed at a certain level could be detected is 28,443. From the data we found there were 738 lncRNAs that differentially expressed (M-bM-^IM-%1.5 fold-change) among preeclampsia placentas compared with matched controls. Up to 18,063 coding transcripts could be detected in placenta samples through 30,215 coding transcripts probes. Coding-non-coding gene co-expression networks (CNC network) were constructed based on the correlation analysis between the differential expressed lncRNAs and mRNAs. According to the GO-Pathway analysis of differential expressed lncRNAs/mRNAs, we choose three lncRNAs to analyze the relationship between lncRNAs and preeclampsia. LOC391533, LOC284100, CEACAMP8 were evaluated by qPCR in 40 of preeclampsia placentas and 40 of controls. The results showed three lncRNAs were aberrantly expressed in preeclampsia placentas compared with controls. Conclusions/Significance: Our study is the first one to determine genome-wide lncRNAs expression patterns in preeclampsia placenta by microarray. The results displayed that clusters of lncRNAs were aberrantly expressed in preeclampsia placenta compared with controls, which revealed that lncRNAs differentially expressed in preeclampsia placenta may exert a partial or key role in preeclampsia development. Misregulation of LOC391533, LOC284100, CEACAMP8 might be associated with preeclampsia. Taken together, this study may provide potential targets for future treatment of preeclampsia and novel insights into preeclampsia biology.
