Data from: Repetitive concussive traumatic brain injury interacts with post-injury foot shock stress to worsen social and depression-like behavior in mice

Kristen C. Klemenhagen, Scott P. O'Brien, David L. Brody & Scott P. O’Brien
The debilitating effects of repetitive concussive traumatic brain injury (rcTBI) have been increasingly recognized in both military and civilian populations. rcTBI may result in significant neurological, cognitive, and affective sequelae, and is often followed by physical and/or psychological post-injury stressors that may exacerbate the effects of the injury and prolong the recovery period for injured patients. However, the consequences of post-injury stressors and their subsequent effects on social and emotional behavior in the context of...

Data from: Fine mapping quanitative trait loci affecting murine external ear tissue regeneration in the LG/J by SM/J advanced intercross line

External ear hole closure in LG/J mice represents a model of regenerative response. It is accompanied by the formation of a blastema-like structure and the re-growth of multiple tissues including cartilage. The ability to regenerate tissue is heritable. An F34 advanced intercross line of mice (Wustl:LG,SM-G34) was generated to identify genomic loci involved in ear hole closure over a 30 day healing period. We mapped nineteen quantitative trait loci (QTL) for ear hole closure. Individual...

Data from: Rapid quantitative pharmacodynamic imaging by a novel method: theory, simulation testing and proof of principle

Kevin J. Black, Jonathan M. Koller, Bradley D. Miller & Brad D. Miller
Pharmacological challenge imaging has mapped, but rarely quantified, the sensitivity of a biological system to a given drug. We describe a novel method called rapid quantitative pharmacodynamic imaging. This method combines pharmacokinetic-pharmacodynamic modeling, repeated small doses of a challenge drug over a short time scale, and functional imaging to rapidly provide quantitative estimates of drug sensitivity including EC50 (the concentration of drug that produces half the maximum possible effect). We first test the method with...

Data from: Echidna venom gland transcriptome provides insights into the evolution of monotreme venom

Emily S. W. Wong, Stewart Nichol, Wesley C. Warren, Katherine Belov & Stewart Nicol
Monotremes (echidna and platypus) are egg-laying mammals. One of their most unique characteristic is that males have venom/crural glands that are seasonally active. Male platypuses produce venom during the breeding season, delivered via spurs, to aid in competition against other males. Echidnas are not able to erect their spurs, but a milky secretion is produced by the gland during the breeding season. The function and molecular composition of echidna venom is as yet unknown. Hence,...

Data from: Differential Expression Analysis for Pathways

Winston A. Haynes, Roger Higdon, Larissa Stanberry, Dwayne Collins & Eugene Kolker
Life science technologies generate a deluge of data that hold the keys to unlocking the secrets of important biological functions and disease mechanisms. We present DEAP, Differential Expression Analysis for Pathways, which capitalizes on information about biological pathways to identify important regulatory patterns from differential expression data. DEAP makes significant improvements over existing approaches by including information about pathway structure and discovering the most differentially expressed portion of the pathway. On simulated data, DEAP significantly...

Data from: Effects of diet on resource utilization by a model human gut microbiota containing Bacteroides cellulosilyticus WH2, a symbiont with an extensive glycobiome

Nathan P. McNulty, Wu Meng, Alison R. Erickson, Chongle Pan, Brian K. Erickson, Eric C. Martens, Nicholas A. Pudlo, Brian D. Muegge, Bernard Henrissat, Robert L. Hettich, Jeffrey I. Gordon & Meng Wu
The human gut microbiota is an important metabolic organ. However, little is known about how its individual species interact, establish dominant positions, and respond to changes in environmental factors such as diet. In the current study, gnotobiotic mice colonized with a simplified model microbiota composed of 12 sequenced human gut bacterial species were fed oscillating diets of disparate composition. Rapid, reproducible and reversible changes in community structure were observed. Time series microbial RNA-Seq analyses revealed...

Data from: The Oxytricha trifallax macronuclear genome: a complex eukaryotic genome with 16,000 tiny chromosomes

Estienne C. Swart, John R. Bracht, Vincent Magrini, Patrick Minx, Xiao Chen, Yi Zhou, Jaspreet S. Khurana, Aaron D. Goldman, Mariusz Nowacki, Klaas Schotanus, Seolkyoung Jung, Robert S. Fulton, Amy Ly, Sean McGrath, Kevin Haub, Jessica L. Wiggins, Donna Storton, John C. Matese, Lance Parsons, Wei-Jen Chang, Michael S. Bowen, Nicholas A. Stover, Thomas A. Jones, Sean R. Eddy, Thomas G. Doak … & Laura F. Landweber
The macronuclear genome of the ciliate Oxytricha trifallax displays an extreme and unique eukaryotic genome architecture with extensive genomic variation. During sexual genome development, the expressed, somatic macronuclear genome is whittled down to the genic portion of a small fraction (~5%) of its precursor “silent” germline micronuclear genome by a process of “unscrambling” and fragmentation. The tiny macronuclear “nanochromosomes” typically encode single, protein-coding genes (a small portion, 10%, encode 2–8 genes), have minimal noncoding regions,...
