Complex in vivo RNA-Seq of a Bacterial Pathogen

Complex in vivo RNA-Seq of a Bacterial Pathogen

Researchers at Umeå University recently found that Yersinia pseudotuberculosis can be used as a model of persistent bacterial infections. They performed in vivo RNA-seq of bacteria in small cecal tissue biopsies at early and persistent stages of infection to determine ...

Are we sequencing too deep?

Are we sequencing too deep?

RNA-seq is increasingly used to study gene expression of various organisms. While it provides a great opportunity to explore genome-scale transcriptional patterns with tremendous depth, it comes with prohibitive costs. Establishing a minimal sequencing depth for required accuracy will guide ...

A comparison of commercially-available total RNA extraction kits

A comparison of commercially-available total RNA extraction kits

This study compared the performance of five commercially available kits in extracting total RNA from small eukaryotic tissue samples (<15 mg). Total RNA was isolated from fathead minnow (Pimephales promelas) tissues (spleen, blood, kidney, embryo, and larvae) using the Qiagen RNeasy® ...

A comprehensive transcriptional portrait of human cancer cell lines

A comprehensive transcriptional portrait of human cancer cell lines

Tumor-derived cell lines have served as vital models to advance our understanding of oncogene function and therapeutic responses. Although substantial effort has been made to define the genomic constitution of cancer cell line panels, the transcriptome remains understudied. Here researchers ...
