Project description:Systemic sclerosis (SSc) is a complex autoimmune disease characterized by microvascular dysfunction, immune dysregulation, and progressive fibrosis, and can be classified into limited cutaneous (lcSSc) and diffuse cutaneous (dcSSc) forms. Primary Raynaud’s phenomenon (RP) is a functional vascular disorder that may precede or occur independently of connective tissue diseases. Circulating microRNAs (miRNAs) have emerged as regulators of vascular and immune processes and can be detected in serum. In this study, serum miRNA profiles were assessed in patients with SSc, including lcSSc and dcSSc subtypes, RP, and healthy controls. Small RNA sequencing was performed in a discovery cohort to characterize circulating miRNA expression across the study groups. Libraries were prepared from serum-derived RNA and sequenced on an Illumina platform. Raw sequencing data were processed using a standardized pipeline for miRNA quantification, and normalized counts were generated for downstream analyses. This dataset provides a resource for the exploration of circulating miRNA profiles in SSc subtypes and RP.
Project description:We used data independent acquisition (DIA) mass spectrometry (MS) to profile ~800 proteinsfrom 122 serum samples Dengue or Zika Trinidadian patients. Two time points were collectedper patient. The DIA MS data were matched against a spectral library generated from high pH/low pH separated pooled serum samples.
Project description:Wildtype mice and Autotaxin-overexpressing transgenic mice, both with and without spontaneous tumor formation, were maintained in a colony. Serum samples from mice in the aforementioned three groups were collected and a random subset of mice were selected for microarray analysis. RNA was extracted from serum and subsequently cDNA was generated and run on two 384-well plates probing for 373 viable targets, including microRNAs, control probes and interplate calibrators. Raw Ct values obtained from qPCR analysis were analyzed using GenEx and graphed using GraphPad Prism.
Project description:A miRNA microarray was performed from HCV infected patient serum samples of bothe genotype 1b and genotype 3a, which are prevalent in India, with the aim of identifying a set of miRNAs which are uniquely differentially expressed during HCV infection. miR-320c, miR-483-5p, miR-134 and miR-198 were found to be upregulated in the patient samples as compared to the controls and are currenty being validated.
Project description:Metabolite analysis of DDW fecal samples, standard methanol extraction. Data were acquired using a Bruker Daltonics maXis Impact and C18 RP-UHPLC. Positive polarity acquisition of LC-MS/MS.
Project description:Retained placenta (RP), a quite common disorder in dairy cows, shows a high negative impact on their health status and milk production. Therefore, the biomarkers indicating the risk for RP could yield benefits in dairy management. The study aimed to investigate the serum proteome as the source of the biomarkers for diagnosing the RP. Using the high-resolution liquid chromatography-tandem mass spectrometry, we compared the composition of serum proteome between 9 cows with the RP and 6 with the physiologic puerperium (PP). Among 651 identified proteins, seven had higher, and three showed lower abundance in RP than in the PP group. The differently abundant proteins participated in 15 pathways: six related to hemostasis, three involved in the lipoprotein metabolism, and the remaining ones associated with redox homeostasis, post-translational modification, scavenging, etc. Validation of the proteomic results, using ELISA and spectrophotometric assays, showed that the two identified proteins, haptoglobin, and lipopolysaccharide-binding protein, could represent reliable RP biomarkers. Our results confirmed that the analysis of serum proteome shed "the light" on the counterparty piece(s) of the RP pathogenesis "puzzle" and could be an efficient "tool" in mining for RP biomarkers.
