A recurring challenge in interpreting genomic data is the assessment of results in the context of existing reference databases. Currently, there is no tool implementing automated, easy programmatic access to curated reference information stored in a diverse collection of large, ...

Next generation sequencing is a key technique in small RNA biology research that has led to the discovery of functionally different classes of small non-coding RNAs in the past years. However, reliable annotation of the extensive amounts of small non-coding ...

There is now a web portal that will provide the required tools and computing power for the research community to help drill down into the genetic make-up of horses. The portal was developed by scientists at the J. Craig Venter Institute, ...
Read More »The Ensembl gene annotation system
The Ensembl gene annotation system has been used to annotate over 70 different vertebrate species across a wide range of genome projects. Furthermore, it generates the automatic alignment-based annotation for the human and mouse GENCODE gene sets. The system is ...

RNA-Seq has become increasingly popular in transcriptome profiling. One aspect of transcriptome research is to quantify the expression levels of genomic elements, such as genes, their transcripts and exons. Acquiring a transcriptome expression profile requires genomic elements to be defined ...

RNA-Seq has become increasingly popular in transcriptome profiling. One aspect of transcriptome research is to quantify the expression levels of genomic elements, such as genes, their transcripts and exons. Acquiring a transcriptome expression profile requires genomic elements to be defined ...
Read More »Reduction of Gene Expression Variability from Single Cells to Populations follows Simple Statistical Laws
Recent studies on single cells and population transcriptomics have revealed striking differences in global gene expression distributions. Single cells display highly variable expressions between cells, while cell populations present deterministic global patterns. The mechanisms governing the reduction of transcriptome-wide variability ...

In ecological studies microbial diversity is nowadays mostly assessed via the detection of phylogenetic marker genes such as 16S ribosomal RNA. However, PCR amplification of these marker genes produces a significant amount of artificial sequences often referred to as chimeras. ...
