Transcriptomic Landscape of Treatment - Naïve Erosive Esophagitis

Project description:Erosive Esophagitis (EE) is one of the common forms of gastroesophageal reflux disease (GERD). We performed transcriptomic analysis (RNA sequencing) of esophageal biopsies from patients with EE and healthy controls to increase understanding of complex cellular and molecular pathways in EE.

The translational landscape of naïve and primed state pluripotency

Project description:Translational control plays a central role in regulation of gene expression and can lead to significant divergence between mRNA- and protein-abundance. The translational landscape of early mammalian development and its impact on cellular proteome, however, remains largely un-explored. Here we used genome-wide approaches combined with time-course analysis to measure the mRNA-abundance, mRNA-translation rate and protein expression during the transition of naïve into primed embryonic stem cells (ESCs). We found that the ground state ESCs cultured with GSK3- and MEK-inhibitors and LIF (2iL) display higher ribosome density on a selective set of mRNAs. These mRNAs show reduced translation during the exit from ground state pluripotency and transition to serum/LIF (SL) culture or upon commitment to primed epiblast-like stem cells (EpiLSCs). Strikingly, integrative analysis with cellular proteome indicate a strong translational buffering of this set of mRNAs in 2iL-ESCs leading to stable protein expression levels. Our data reveal that the global alteration of cellular proteome is largely accompanied by transcriptional rewiring. Furthermore, we identified a set of genes (including UHRF1 and KRAS) that undergo selective post-translational regulation during the transition of naïve into primed pluripotency and linked the observed changes to upstream GSK- and MEK/MAPK-signaling pathways using single inhibitor treated ESCs. Thus, we provide a comprehensive and detailed overview of the global changes in gene expression during the transition of naïve to primed pluripotency and dissect the relative contributions of RNA-transcription, translation and regulation of protein stability in controlling protein abundance.

Single Cell Transcriptomic Analysis of Popliteal Lymph Nodes from TNF-Tg Mice with Early and Advanced Inflammatory-Erosive Arthritis

Project description:Immune cell dynamics in lymph nodes downstream of inflamed joints are associated with inflammatory-erosive arthritis in both tumor necrosis factor transgenic (TNF-Tg) mice and rheumatoid arthritis (RA) patients. In TNF-Tg mice, "Early" stages of arthritis are related to dramatic PLN "Expansion" with increases in joint-draining popliteal lymph node (PLN) volume and fluid flow, while CD21-high / CD23+ B-cells in inflamed nodes (Bin cells) accumulate in the PLN follicles. Onset of "Advanced" inflammatory-erosive arthritis is related to a PLN "Collapse" where fluid flow is reduced as Bin cells translocate from the PLN follicles into the sinuses and are thought to mechanically inhibit lymphatic drainage. Through single-cell RNA-sequencing, we aimed to evaluate changes in PLN immune cell populations during Early and Advanced arthritis to determine mechanisms mediating the Bin cell translocation and the relationship with arthritic progession in the afferent joints.

Gender-specific Effect of Micronutrient on Non-erosive Reflux Disease and Erosive Esophagitis.

Project description:Background/aimsThe effect of dietary micronutrients on non-erosive reflux disease (NERD) and reflux esophagitis is unclear. We aim to evaluate the gender-specific effect of micronutrient on erosive esophagitis and NERD.MethodsA total of 11 690 participants underwent endoscopy and completed 3-day recordings for dietary intake and questionnaires for reflux symptoms from 2004 to 2008. To evaluate the effect of dietary micronutrients on NERD or erosive esophagitis, adjusted regression analysis with odds ratio (OR) and 95% confidence interval (CI) was used. In addition, we performed gender-specific analysis.ResultsPrevalence of NERD and erosive esophagitis was 6.8% and 11.2% in men and 9.1% and 2.4% in women. In adjusted analysis, high intake of vitamin A (OR, 0.78; 95% CI, 0.64-0.96), retinol (OR, 0.73; 95% CI, 0.59-0.90), vitamin B2 (OR, 0.68; 95% CI, 0.54-0.87), vitamin B6 (OR, 0.75; 95% CI, 0.58-0.96), folic acid (OR, 0.77; 95% CI, 0.62-0.96), calcium (OR, 0.66; 95% CI, 0.53-0.82), and iron (OR, 0.68; 95% CI, 0.53-0.87) had an inverse association with NERD. However, erosive esophagitis has no relationship with micronutrients except vitamin C (OR, 0.78; 95% CI, 0.62-0.98). High dietary intake of calcium reduced the risk of NERD in men and high dietary intake of many micronutrients reduced NERD in women.ConclusionsWhile many dietary micronutrients reduced NERD, they had no effect on erosive esophagitis. The effect of micronutrient on NERD was more prominent in women than men.
