RNA-sequencing (RNA-seq) and microarrays are methods for measuring gene expression across the entire transcriptome. Recent advances have made these techniques practical and affordable for essentially any laboratory with experience in molecular biology. A variety of computational methods have been developed ...Read More »
Exon-junction arrays – a viable alternative to RNA-seq for detection of alternative splicing events?
RNA-seq is a reference technology for determining alternative splicing at genome-wide level. Exon arrays remain widely used for the analysis of gene expression, but show poor validation rate with regard to splicing events. Commercial arrays that include probes within exon ...Read More »
The analysis of small RNA NGS data together with the discovery of new small RNAs is among the foremost challenges in life science. For the analysis of raw high-throughput sequencing data Saarland University researchers implemented the fast, accurate and comprehensive ...Read More »
Use of ‘omics technologies in environmental science is expanding. However, application is mostly restricted to characterizing molecular steps leading from toxicant interaction with molecular receptors to apical endpoints in laboratory species. Use in environmental decision-making is limited, due to difficulty ...Read More »
Malignant tumors of the central nervous system (CNS) cause substantial morbidity and mortality, yet efforts to optimize chemo- and radiotherapy have largely failed to improve dismal prognoses. Over the past decade, RNA sequencing (RNA-seq) has emerged as a powerful tool ...Read More »
RNA sequencing (RNA-Seq) and microarray are two of the most commonly used high-throughput technologies for transcriptome profiling; however, they both have their own inherent strengths and limitations. Researchers from Fudan University aimed to analyze the correlation between microarrays and RNA-Seq detection of ...Read More »
Gene Expression Signatures for Cancer Patient Stratification: Are Results Ready for Clinical Application?
Head and neck squamous cell carcinoma (HNSCC) is the sixth leading cancer by incidence worldwide and considering the recent EUROCARE-5 population-based study the 5-year survival rate of HNSCC patients in Europe ranges between 69% in localized cases and 34% in ...Read More »
To meet the increasing demand in the field, numerous long noncoding RNA (lncRNA) databases are available. Given many lncRNAs are specifically expressed in certain cell types and/or time-dependent manners, most lncRNA databases fall short of providing such profiles. Researchers at ...Read More »
Natural antisense transcripts, originally considered as transcriptional noises arising from so-called “junk DNA”, are recently recognized as important modulators for gene regulation. They are prevalent in nearly all realms of life and have been found to modulate gene expression positively ...Read More »
University of Cambridge researchers describe new method for revealing short-term changes in gene expression, alterations in RNA decay rates, and the kinetics of RNA processing
Cellular RNA levels are orchestrated by highly regulated processes involving RNA synthesis (transcription), processing (e.g., splicing, polyadenylation, transport), and degradation. Profiling these changes provides valuable information on the regulation of gene expression. Total cellular RNA is a poor template for ...Read More »
