Evaluating bias-reducing protocols for RNA sequencing library preparation

Project description:The ligation step in RNA sequencing library generation is a known source of bias. We present the first comparison of the standard duplex adaptor protocol supplied by Life Technologies for use on the Ion Torrent PGM with an alternate single adaptor approach involving CircLigase (CircLig). We also investigate whether using the thermostable ligase Methanobacterium thermoautotrophicum RNA ligase K97A (Mth K97A) for the initial ligation step in the CircLigase protocol reduces bias. A pool of small RNA fragments of known composition was converted into a sequencing library using one of three protocols and sequenced on an Ion Torrent PGM. The single adaptor CircLigase-based approach significantly reduces, but does not eliminate, bias in Ion Torrent data. Using Mth K97A as part of the CircLig method does not further reduce bias.

Variations of Metabolites and Proteome from Lonicera japonica Thunb. Buds Blossom to Flowers under UV Radiation

Project description:Lonicera japonica Thunb., known as Jin Yin Hua or Japanese honeysuckle, is an herbal medicine in Asian countries. Its flowers have been used as folk medicine for clinical practice or used as food or making healthy beverage for 1500 years in China. To investigate the molecular developmental processes from L. japonica buds to flowers under UV radiation, comparative proteomics analyses of buds and flowers were performed. Fifty-four differential proteins were identified including 42 increased proteins and 12 decreased proteins. The abundance of proteins related to glycolysis, TCA/organic acid transformation, major carbohydrate metabolism, oxidative pentose phosphate, stress, secondary metabolism, hormone, and mitochondrial electron transport were increased during flower opening process under UV radiation. Six metabolites were identified and relatively quantified by LC-MS/MS in L. japonica buds and flowers. The 1,1-diphenyl-2-picrylhydrazyl assay revealed that antioxidant activity of L. japonica buds was better than that of flowers. These results suggest that UV-B radiation could induce the production of endogenous ethylene in L. japonica buds, which facilitate the buds blossom and activate the antioxidant system. Additionally, the higher content of metabolites and antioxidant capability in L. japonica buds indicates that L. japonica buds stage might be the better harvest time compared to the flower.

Auxin Response Factor mediated flower gene expression

Project description:The aim of this study was to examine the contribution of ARF6 and ARF8 to flower gene expression. Flowers from arf6 arf8 plants undergo a developmental arrest at approximately stage 12, just prior to flower opening. Flowers from wild-type, ARF6/arf6 arf8/arf8, and arf6 arf8 plants were separated into stage 1-10 flowers, stage 11+12 flowers, and stage 13-14 flowers to define the developmental stages at which ARF6 and ARF8 are required for gene expression. Keywords: comparison of wild type and arf6 arf8 mutants

Dye Bias Array Set

Project description:Spot intensity serves as a proxy for gene expression in dual-label microarray experiments. Dye bias is defined as an intensity difference between samples labeled with different dyes attributable to the dyes instead of the gene expression in the samples. Dye bias that is not removed by array normalization can introduce bias into comparisons between samples of interest. But if the bias is consistent across the samples for the same gene, it can be corrected by proper experimental design and analysis. If the dye bias is not consistent across samples for the same gene, but is different for different samples, then removing the bias becomes more problematic, perhaps indicating a technical limitation to the ability of fluorescent signals to accurately represent gene expression. Thus, it is important to characterize dye bias to determine: (1) whether it will be removed for all genes by array normalization, (2) whether it will not be removed by normalization but can be removed by proper experimental design and analysis and (3) whether dye bias correction is more problematic than either of these and is not easily removable. Keywords: dye swap design
