MetabolomicsDynamic Characteristics of Primary and Secondary Polar Metabolites in Cabernet Sauvignon Grapes at Different Growth Stages in the Ningxia Wine Region

This study focuses on the Helan Mountain East Foothills region of Ningxia, a typical continental climate wine-growing area, with Cabernet Sauvignon grapes as the subject. It combines trime-thylsilyl derivatization -Gas Chromatography-Mass Spectrometry (TMS-GC-MS) technology and the independently ...

MetabolomicsUntargeted and Targeted Plasma Metabolomics Analysis Identifies Aberrant Amino Acid Metabolism in Early Primary Angle-Closure Glaucoma

Purpose: To explore the plasma metabolite profiles of patients with early primary angle-closure glaucoma (PACG) and investigate their relevance to ocular characteristics and retinal-associated parameters.

Methods：Plasma samples were obtained from 30 early PACG patients and 30 healthy contro...

GenomicsChromatin and Sequence Features that Define the Fine and Gross Structure of Genomics Methylation Patterns
We report a new method for genome-wide methylation profiling that is able to probe methylation status in both single-copy DNA and interspersed repeats. This method, MethylMAPS, uses methylation-sensitive and -dependent enzymes to fractionate the genome according to methylation state. Methylated an...

TranscriptomicsVariation in homeodomain DNA-binding revealed by high-resolution analysis of sequence preferences
Most homeodomains are unique within a genome, yet many are highly conserved across vast evolutionary distances, implying strong selection on their precise DNA-binding specificities. We determined the binding preferences of the majority (168) of mouse homeodomains to all possible 8-base sequences, re...

TranscriptomicsMicroRNA sequence and expression analysis in breast tumors by deep sequencing [miRNA sequence data]
MicroRNAs (miRNAs) regulate many genes critical for tumorigenesis. We profiled miRNAs from 11 normal breast tissues, 17 non-invasive, 151 invasive breast carcinomas, and 6 cell lines by in-house-developed barcoded Solexa sequencing. miRNAs were organized in genomic clusters representing promoter-con...

Transcriptomicscis sequence effects on gene expression
Sequence and transcriptional variability within and between individuals are typically studied independently. The joint analysis of sequence and gene expression variation provides insight into biological mechanisms that underlie gene regulation and function. We investigated the role of sequence varia...

TranscriptomicsU87MG Decoded: The Genomic Sequence of a Cytogenetically Aberrant Human Cancer Cell Line
U87MG is a commonly studied grade IV glioma cell line that has been analyzed in at least 1,700 publications over four decades. In order to comprehensively characterize the genome of this cell line and to serve as a model of broad cancer genome sequencing, we have generated greater than 30x genomic s...

TranscriptomicsDigital RNA Sequencing Minimizes Sequence-Dependent Bias and Amplification Noise with Optimized Single Molecule Barcodes
RNA-Seq is a powerful tool for transcriptome profiling, but is hampered by sequence-dependent bias and inaccuracy at low copy numbers intrinsic to exponential PCR amplification. We developed a simple strategy for mitigating these complications, allowing truly digital RNA-Seq. Following reverse tra...

TranscriptomicsDeep Sequence Analysis of the Relationship between Gene Expression, CpG Island Methylation, and Gene Copy Number in Breast Cancer Cells
We used deep sequencinge technology to profile the transcriptome, gene copy number, and CpG island methylation status simultaneously in eight commonly used breast cell lines to develop a model for how these genomic features are integrated in estrogen receptor positive (ER+) and negative breast cance...
