Normalization of RNA-sequencing data is essential for accurate downstream inference, but the assumptions upon which most methods are based do not hold in the single-cell setting. Consequently, applying existing normalization methods to single-cell RNA-seq data introduces artifacts that bias downstream ...

by Shelby Lyon of the Journal Sentinel – When a sheriff’s deputy found a van parked at the edge of Sparkling Lake in Vilas County at 2 a.m. on July 7, chances are he expected to find something nefarious afoot. ...

MADISON, Wis. — In one of the first studies to ‘read’ the genetic activity inside individual brain cells, University of Wisconsin-Madison neuroscientist Xinyu Zhao has identified the genetic machinery that causes maturation in a young nerve cell. The cells under ...

Mass spectrometry-based proteomic analysis underestimates proteomic variation due to the absence of variant peptides and posttranslational modifications (PTMs) from standard protein databases. Each individual carries thousands of missense mutations that lead to single amino acid variants, but these are missed ...

2015 Network Analysis Short Course – Systems Biology Analysis Methods for Genomic Data Speaker: Christina Kendziorski, University of Wisconsin-Madison The goal of the network analysis workshop is to familiarize researchers with network methods and software for integrating genomic data sets ...

Oscillatory gene expression is fundamental to development, but technologies for monitoring expression oscillations are limited. Researchers at the University of Wisconsin-Madison have developed a statistical approach called Oscope to identify and characterize the transcriptional dynamics of oscillating genes in single-cell ...

Current practice in mass spectrometry (MS)-based proteomics is to identify peptides by comparison of experimental mass spectra with theoretical mass spectra derived from a reference protein database; however, this strategy necessarily fails to detect peptide and protein sequences that are ...

The nematode Caenorhabditis elegans is an important model for studies of germ cell biology, including the meiotic cell cycle, gamete specification as sperm or oocyte and gamete development. Fundamental to those studies is a genome-level knowledge of the germline transcriptome. ...
