Project description:Podocyte injury is involved in the onset and progression of various kidney diseases. We previously demonstrated that the transcription factor, old astrocyte specifically induced substance (OASIS) in myofibroblasts, contributes to kidney fibrosis, as a novel role of OASIS in the kidneys. Importantly, we found that OASIS is also expressed in podocytes; however, the pathophysiological significance of OASIS in podocytes remains unknown. Upon lipopolysaccharide (LPS) treatment, there is an increase in OASIS in murine podocytes. Enhanced serum creatinine levels and tubular injury, but not albuminuria and podocyte injury, are attenuated upon podocyte-restricted OASIS knockout in LPS-treated mice, as well as diabetic mice. The protective effects of podocyte-specific OASIS deficiency on tubular injury are mediated by protein kinase C iota (PRKCI/PKCι), which is negatively regulated by OASIS in podocytes. Furthermore, podocyte-restricted OASIS transgenic mice show tubular injury and tubulointerstitial fibrosis, with severe albuminuria and podocyte degeneration. Finally, there is an increase in OASIS-positive podocytes in the glomeruli of patients with minimal change nephrotic syndrome and diabetic nephropathy. Taken together, OASIS in podocytes contributes to podocyte and/or tubular injury, in part through decreased PRKCI. The induction of OASIS in podocytes is a critical event for the disturbance of kidney homeostasis.

Project description:Investigation of whole genome gene expression level changes in OASIS KO calvaria compared to wild-type calvaria. To gain further insight into the potential mechanisms underlying the defective bone formation in OASIS KO mice, we compared the gene expression in calvaria between WT and OASIS KO mice using a microarray. Each sample of total RNA was collected from a number of mice.

Project description:To investigate the roles of OASIS/CREB3L1 in astrocytes during DNA damage response, we established OASIS wild type and deficient primary cultured mouse astrocytes treated with or without anti-cancer drug doxorubicin. We then performed gene expression profiling analysis using data obtained from RNA-seq of 4 different cells.

Project description:Purpose: The goals of this study is to compare and profile the smallRNA transcriptome of the placenta in preeclamptic and normal patients using RNA sequencing. Methods: Placental and Placental vesicles (STB-EVs) smallRNA profiles of normal and preeclamptic patients were generated by deep sequencing using Illumina HISEQ. FASTq.gz files were compressed with OASIS compressor and alignment was done with OASIS 2.0 ( by trimmimng with trimmomatic, aligning using default OASIS 2.0 aligning papameters). Quantitative PCR validation was performed using TaqMan gene expression assays Results: This contains a set of three parallel smallRNA sequencing experiments involving placenta tissue, medium/large STB-EVs and small STB-EVs. Comparison between PE and normal pregnancy placental tissue revealed 134 (p-value of <0.05 ) while in medium/large STB-EVs, 101 and in small STB-EVs, 16 (adjusted P-value of <0.05) differentially expressed small RNA We identified a number of mechanistic and biomarker targets, which were validated with qRT–PCR and confirmed to be signifficantly DE. The differentially expressed analysis identified potential yet undescribed small RNAs that may contribute to the pathogenesis of preeclampsia or/and may act as biomarkers of the disease. Conclusions: Our study represents the first combined analysis of placenta, medium/large and small STB-EV transcriptomes, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results identified potential Placenta EV small RNA biomarkers that can help diagnose the preeclampsia

Project description:D-galactose orally intake ameliorate DNCB-induced atopic dermatitis by modulating microbiota composition and quorum sensing. The increased abundance of bacteroidetes and decreased abundance of firmicutes was confirmed. By D-galactose treatment, Bacteroides population was increased and prevotella, ruminococcus was decreased which is related to atopic dermatitis.

Project description:The main goal of the project is the study the associations between the gut metagenome and human health. The dataset contains data for n=7211 FINRISK 2002 participants who underwent fecal sampling. Demultiplexed shallow shotgun metagenomic sequences were quality filtered and adapter trimmed using Atropos (Didion et al., 2017), and human filtered using Bowtie2 (Langmead and Salzberg, 2012).
