Proteome analysis of human serum and plasma under the different pre-analytical processing

ABSTRACT: The storage conditions after collecting blood are expected to influence blood proteome. The present project assessed the differences in proteome between human serum and plasma, and stability of human plasma proteins under different storing duration at room temperature (0-30 min) and cold temperature (1-8 h).

The purpose of the present study was to assess the differences between the human serum and plasma proteomes, and the stability of human plasma proteins under different storage conditions following blood collection, by means of SWATH-MS analysis. When we compared plasma and serum prepared immediately after blood sampling, 95.5% of 176 quantified proteins differed by less than 1.5-fold. When we compared plasma samples prepared by centrifugation after storage of blood at room temperature for 0, 15 ...[more]

Genome-wide analysis of the effect of long-term freezing of PAXgene Blood RNA tubes

Project description:Analysis of long-term freezing on the stability of transcriptome profiles in PAXgene stabilized whole blood samples. In the present study it was tested if long-term freezing of PAXgene RNA tubes (up to one year) has an influence on the transcriptome profile of peripheral whole blood samples. Results indicated that gene expression profiles of whole blood samples stabilized with PAXgene RNA tubes remain stable for at least 1 year. Total RNA was obtained from peripheral whole blood samples collected in PAXgene RNA tubes of healthy human subjects. RNA was either isolated after 24h storage at room temperature or after freezing of PAXgene RNA tubes for up to 1 year (6 weeks, 6 months and 12 months).

RNA-Seq of rice endosperm under high temperature

Project description:High temperature during the grain-filling stage causes deleterious effects on storage material accumulation and grain quality. But it is still unclear how high temperature affects storage materials accumulation. In this study, we systemically analyzed the expression pattern of rice genes under high temperture during the grain-filling stage.

LC-MS/MS of Human Plasma Peptides

Project description:Discrepancies in blood sample collection and processing could have a significant impact on levels of peptides in the blood, thus sample quality control is critical for successful biomarker identification and validation. In this study, we analyzed the effects of several pre-analytical processing conditions, including different storage times and temperatures of blood or plasma samples and different centrifugation forces, on the levels of peptides in human plasma samples using ethylenediaminetetraacetic acid (EDTA) as an anticoagulant. Both time and temperature were identified as major factors for peptide variation.

The Effect of Calcium on Activity, Immunogenicity and Efficacy of a Recombinant N1/N2 Neuraminidase Vaccine

Project description:Despite the importance of immunity against neuraminidase (NA), NA content and immunogenicity is neglected in current influenza vaccines. To address this, a novel recombinant N1/N2 NA vaccine (NAV) was developed. Stability assays were used to determine optimal temperature and buffer conditions for vaccine storage. The effect of calcium-related enhancement of NA stability and activity on N1 and N2 immunogenicity and efficacy against viral challenge was assessed. Differences in activity between N1 and N2 and calcium-related activity enhancement did not translate into differences in immunogenicity or efficacy. NAV vaccinated mice showed robust antibody titers against N1 and N2, decreased viral titers, and decreased antiviral and inflammatory responses by transcriptomic analysis.

Expression data from postharvest Ponkan (Citrus reticulata Blanco) fruit under cold storage

Project description:Low temperature storage of citrus fruits are susceptible to chilling disorder symptoms that impact fruit quality. Understanding the molecular frame underlying the cold storage process will provide a basic guidance for practical control. We used Affymetrix Citrus GeneChip to examine the transcriptional changes in cold-stored Citrus reticulata Blanco cv. ‘Ponkan’ pulp tissue for three successive months.

Plasma Biomarker Profile Altered Through Variable Blood Storage

Project description:A major confounding factor for defining disease-specific molecular signatures is the variation in handling and processing of clinical samples. To address this, we assessed how the plasma proteome and degradome changes when whole blood remains at ambient temperature (AT) following collection and prior to processing.

Aspergillus flavus transcriptome under different temperature conditions

Project description:To better understand the effect of temperature on mycotoxin biosynthesis, RNA-Seq technology was used to profile the Aspergillus flavus transcriptome under different temperature conditions. This approachallowed us to quantify transcript abundance for over 80% of fungal genes including 1,153 genes that were differentially expressed at 30°C and 37°C. Wleven of the 55 secondary metabolite clusters were up-regulated at the lower temperature, including aflatoxin biosynthesis genes, which were among the most highly up-expressed genes. On average, transcript abundance for the 30 aflatoxin biosynthesis genes was 3,300 times greater at 30°C as compared to 37°C. The results are consistent with the view that high temperature negatively affects aflatoxin production by turning down transcription of the two key transcriptional regulators, aflR and aflS. Subtle changes in the expression levels of aflS to aflR appear to control transcription activation of the aflatoxin cluster.
