Project description:Transcriptional profiling of E. faecalis E99 WT and an isogenic ΔperA strain grown in THB + 1% glucose. Pathogenic E. faecalis are enriched for a pathogenicity island (PAI). This 150-kb island harbors a number of well characterized virulence genes plus a number of determinants of unknown function including one encoding a transcriptional regulator, designated PerA. In this work, we show that PerA coordinately regulates both metabolic and virulence genes, and influences the platelet binding ability of E. faecalis. Finally, we show that PerA responds to bicarbonate, an intestinal ion frequently used by pathogens to determine the site of infection. Together, these results indicate that PerA is a global transcriptional regulator that coordinately regulates genes responsible for enterococcal pathogenicity. These findings highlight a novel feature of PAI-mediated virulence regulation, namely the coordinate regulation of metabolic and virulence factors in the core genome by a horizontally acquired PAI-encoded transcriptional regulator.

RNA was obtained from E. faecalis E99 ΔperA from mid-log (OD600 0.05), late log (OD600 0.5) and stationary phase (OD600 1.0) and compared to E. faecalis E99 WT RNA extracted from the same growth phases. Cultures were grown in THB + 1% glucose.

Project description:Second messenger nucleotides such as c-di-AMP are produced by bacteria in response to environmental stimuli and can contribute to the regulation of a number of cellular processes including osmoregulation, envelope homeostasis, central metabolism, and biofilm formation. Here, as part of an effort to uncover the biological significance of c-di-AMP in the opportunistic pathogen Enterococcus faecalis, we utilized high-throughout RNA Sequencing analysis to explore the impact of deletion of genes responsible for c-di-AMP synthesis (cdaA) and degradation (dhhP and gdpP).

Project description:Background: Electroacupuncture (EA) were progressively gained popularity in the treatment of neurological disorders such as ischaemic brain injury in recent years. But the therapeutic mechanisms of EA are yet not well addressed. This research aims to explore the effect of electroacupuncture stimulation of Lung Meridian of Hand-Taiyin on synaptic plasticity in rats with cerebral ischemia-reperfusion injury based on Transcriptomics Methods: Rats were randomly divided into sham operation group, model group and EA group. Rats in the model group and the EA group were prepared for the middle cerebral artery occlusion/reperfusion (MCAO/R) model. In the EA group, the representative acupoints of the Lung Meridian of Hand-Taiyin (Tianfu acupoints, Chize acupoints, Kongzui acupoints and Taiyuan acupoints) were selected for electroacupuncture stimulation. Transcriptomics was performed after the intervention.

Project description:Aim: To study the effect of electroacupuncture (EA) on circRNA expression of plasma Exosomes and signal pathway of type 2 diabetic mice (T2DM). Methods: 10 mice were randomly selected as normal group. 20 mice were for T2DM model preparation and then were randomly divided into model and model + EA group. Mice in model + EA group were given EA treatment. The changes of fasting blood glucose (FBG) and the Islet structure were evaluated. Plasma exosomes of mice were subjected to RNA sequencing. Bioinformatics analysis on differentially expressed circRNA was performed. 12 differentially expressed circRNA were confirmed for real-time quantitative PCR (qPCR). Results: EA treatment reduced the FBG, preserved islets structure and reduced the islet β cell apoptotic rate of T2DM mice. RNA-sequencing analysis showed EA treatment lead to significant change of 165 circRNA expressions. GO and KEGG revealed that the effects of EA on T2DM mainly focus on regulating the functions and pathways related to multi-link metabolism, cell growth and organ development. Especially, the thyroid hormone signaling pathway was actively regulated by EA. circRNA/miRNA interactions analysis revealed that that mmu-mir-7092-3p was closely combined with circINPP4B, suggesting phosphatidylinositol signaling pathway was affected by EA. 12 circRNAs were identified to have significant differences by qRT-PCR. Conclusion: EA intervention can significantly protect islet function and improve FBG in T2DM, which may be related to the regulation on thyroid hormone and Phosphatidylinositol signaling pathway.

Project description:Enterococcus faecalis is a major nosocomial pathogen frequently isolated from non- healing wound infections. The major factor responsible for the virulence and establishment of infection is its ability to form robust biofilm. This renders the recalcitrant nature of Enterococci towards the current treatment strategies. In the present study, the quantitative proteomic approach is carried out to elucidate the protein expression levels in E. faecalis at planktonic and biofilm stages. This will help to identify biofilm associated pathways in E. faecalis which inturn can be considered as novel targets for biofilm inhibition.

Project description:The FITExP profiling approach was used to identify protein hits from cells incubated with RAPTA-T or RAPTA-EA. Validation experiments with paclitaxel and cisplatin underlined the reliability of the method and hit lists for both test compounds (and?) gave physiologically viable anti-cancer mechanisms. The hit proteins for paclitaxel match with those published and the ones obtained for cisplatin were related to DNA repair, which is in line with the principal mechanism of cisplatin cytotoxicity involving the formation of nuclear DNA lesions. RAPTA-T treatment leads to upregulation of multiple hits suggesting a broad mechanism of action involving both metastasis and tumorigenicity. In contrast, hit proteins identified after incubation with RAPTA-EA are linked to regulation of the oxidative stress response and are therefore thought to be conferred by the EA moiety in the drug. From a therapeutic standpoint, RAPTA-EA could be explored in cancers where EA alone has shown potency, such as chronic lymphocytic leukemias,91 or where EA combined with another agent shows synergy, such as the combination of EA with afatinib, an irreversible epidermal growth factor receptor tyrosine kinase inhibitors for breast cancers.92 On the other hand, due to its broad mechanism of action, RAPTA-T could potentially be more useful if used concomitantly with drugs that target specific cancer pathways and could also play a role in therapies for later stage cancers due to its anti-metastatic properties. Here, application of the FITExP allowed us to gauge the mechanistic pathways involved in the action of two novel ruthenium(II) metallodrugs with very different phenotypic characteristics and from this knowledge infer their role in therapy. Potentially, future application of the FITExP approach in this manner could be useful for identification of cancer chemotherapy drug combinations, where commonly cancer clinical trials fail at phase II where drug combinations are first tried and tested.

Project description:The m⁶A reader proteins YTHDF1–3 are key post-transcriptional regulators of methylated transcripts and have been implicated in the progression of triple-negative breast cancer (TNBC). Owing to their roles in sustaining malignant phenotypes, YTHDF1–3 are attractive targets for therapeutic intervention. Here, we identify ellagic acid (EA), a naturally occurring polyphenol, as a pan-inhibitor of YTHDF proteins. To investigate the effect of YTHDF inhibition on mRNA stability, we performed RNA lifetime sequencing (RNA lifetime-seq) to profile transcriptome-wide RNA decay dynamics in EA-treated TNBC cells.
