METTL3-mediated m6A modification of EGR1 mRNA promotes T2DM vasculopathy.

Vascular endothelial dysfunction is one of the leading causes of developing vascular lesions in Type 2 diabetes mellitus (T2DM). In the development of vascular lesions, when endothelial cells are stimulated by hyperglycemia, inflammation and other external conditions, endothelial cell dysfunction will occur, which promotes endothelial cells to lose its typical phenotype and gain mesenchymal characteristics, with the occurrence of endothelial-to-mesenchymal transition (EndMT). At the same time promote endothelial cell proliferation and migration, induce vascular injury.

Comprehensive analysis of the mA demethylase FTO in endothelial dysfunction by MeRIP sequencing.

N6-methyladenosine (m6A) is the most general post-transcriptional modification of eukaryotic mRNAs and long-stranded non-coding RNAs. In this process, It has been shown that FTO associates with the m6A mRNA demethylase and plays a role in diabetic vascular endothelial dysfunction. In the present study, we detected FTO protein expression in HUVECs by Western blot and found that FTO was highly expressed in all disease groups relative to the control group.

Characterization of gut microbial and metabolite alterations in faeces of Goto Kakizaki rats using metagenomic and untargeted metabolomic approach.

Background: In recent years, the incidence of type 2 diabetes (T2DM) has shown a rapid growth trend. Goto Kakizaki (GK) rats are a valuable model for the study of T2DM and share common glucose metabolism features with human T2DM patients. A series of studies have indicated that T2DM is associated with the gut microbiota composition and gut metabolites.

Effect of berberine on hyperglycaemia and gut microbiota composition in type 2 diabetic Goto-Kakizaki rats.

Background: A recent investigation showed that the prevalence of type 2 diabetes mellitus (T2DM) is 12.8% among individuals of Han ethnicity. Gut microbiota has been reported to play a central role in T2DM.

Novel Polysaccharide H-1-2 from Pseudostellaria Heterophylla Alleviates Type 2 Diabetes Mellitus.

Background/aims: To investigate the potential therapeutic effect of novel polysaccharide H-1-2 from pseudostellaria heterophylla against type 2 Diabetes Mellitus (T2DM) and elucidate the underling molecular mechanisms.

Methods: Relative expression of HIF1α and Sirt1 in T2DM patients was determined via real-time PCR. The direct binding of HIF1α on Sirt1 promoter was validated by ChIP assay.

Effect of vitamin D on ventricular remodelling in heart failure: a meta-analysis of randomised controlled trials.

Objectives: The level of vitamin D is considered to be associated with the development and progression of heart failure (HF). However, it is still unclear whether supplementation of vitamin D could improve ventricular remodelling in patients with HF. This study aimed to systematically evaluate the influence and safety of additional vitamin D supplementation on ventricular remodelling in patients with HF.

[Research advances on astragaloside-IV in treatment of diabetes mellitus and its complications pharmacological effects].

Diabetes has become a global public health problem that seriously threatens human health. Traditional Chinese medicine, the characteristics of the role of multiple targets, has a unique advantage in the prevention and treatment of diabetes mellitus and its complications. Astragaloside-Ⅳ (AS-Ⅳ), one of the main activities of Astragalus membranaceus, has a series of pharmacological effects including improvement in the function of endothelial cells and neovascularization, anti-inflammatory, antioxidant, regulating energy metabolism, protectionnervous, anti-cancer and so on.

Integrated transcriptomic and proteomic analysis of the global response of Synechococcus to high light stress.

Sufficient light is essential for the growth and physiological functions of photosynthetic organisms, but prolonged exposure to high light (HL) stress can cause cellular damage and ultimately result in the death of these organisms. Synechococcus sp. PCC 7002 (hereafter Synechococcus 7002) is a unicellular cyanobacterium with exceptional tolerance to HL intensities.

Proteogenomic analysis and global discovery of posttranslational modifications in prokaryotes.

We describe an integrated workflow for proteogenomic analysis and global profiling of posttranslational modifications (PTMs) in prokaryotes and use the model cyanobacterium Synechococcus sp. PCC 7002 (hereafter Synechococcus 7002) as a test case. We found more than 20 different kinds of PTMs, and a holistic view of PTM events in this organism grown under different conditions was obtained without specific enrichment strategies.

Global phosphoproteomic analysis reveals diverse functions of serine/threonine/tyrosine phosphorylation in the model cyanobacterium Synechococcus sp. strain PCC 7002.

Increasing evidence shows that protein phosphorylation on serine (Ser), threonine (Thr), and tyrosine (Tyr) residues is one of the major post-translational modifications in the bacteria, involved in regulating a myriad of physiological processes. Cyanobacteria are one of the largest groups of bacteria and are the only prokaryotes capable of oxygenic photosynthesis. Many cyanobacteria strains contain unusually high numbers of protein kinases and phosphatases with specificity on Ser, Thr, and Tyr residues.

Efficacy of percutaneous kyphoplasty in treating osteoporotic multithoracolumbar vertebral compression fractures.

Percutaneous kyphoplasty is a minimally invasive technique that has become an effective and routine alternative for managing osteoporotic vertebral compression fractures. This article reports the clinical outcome of a series of 54 cases of osteoporotic thoracolumbar vertebrae compression fractures treated by percutaneous kyphoplasty. Fifty-four patients with confirmed osteoporosis and at least 1 level of thoracolumbar vertebrae compression fracture were retrospectively selected.

PII, the key regulator of nitrogen metabolism in the cyanobacteria.

PII proteins are a protein family important to signal transduction in bacteria and plants. PII plays a critical role in regulation of carbon and nitrogen metabolism in cyanobacteria. Through conformation change and covalent modification, which are regulated by 2-oxoglutarate, PII interacts with different target proteins in response to changes of cellular energy status and carbon and nitrogen sources in cyanobacteria and regulates cellular metabolism.

[Expression and characterization of FNRD in cyanobacterium Synechococcus sp. PCC 7002].

The petHL genes under the control of Lac and Kan promoters were transformed into Synechococcus sp. PCC 7002, respectively. Both of the petHL genes are integrated into the cyanobacterium chromosomes, which is inferred from the results of Southern blot analysis.

Genome-wide ORFeome cloning and analysis of Arabidopsis transcription factor genes.

Here, we report our effort in generating an ORFeome collection for the Arabidopsis transcription factor (TF) genes. In total, ORFeome clones representing 1,282 Arabidopsis TF genes have been obtained in the Gateway high throughput cloning pENTR vector, including 411 genes whose annotation lack cDNA support. All the ORFeome inserts have also been mobilized into a yeast expression destination vector, with an estimated 85% rate of expressing the respective proteins.
