Data from: Structural and mechanistic basis of zinc regulation across the E. coli Zur regulon

Benjamin A. Gilston, Suning Wang, Mason D. Marcus, Mónica A. Canalizo-Hernández, Elden P. Swindell, Yi Xue, Alfonso Mondragón & Thomas V. O'Halloran
Commensal microbes, whether they are beneficial or pathogenic, are sensitive to host processes that starve or swamp the prokaryote with large fluctuations in local zinc concentration. To understand how microorganisms coordinate a dynamic response to changes in zinc availability at the molecular level, we evaluated the molecular mechanism of the zinc-sensing zinc uptake regulator (Zur) protein at each of the known Zur-regulated genes in Escherichia coli. We solved the structure of zinc-loaded Zur bound to...

Data from: Implicit racial attitudes influence perceived emotional intensity on other-race faces

Qiandong Wang, Guowei Chen, Zhaoquan Wang, Chao S. Hu, Xiaoqing Hu & Genyue Fu
An ability to accurately perceive and evaluate out-group members' emotions plays a critical role in intergroup interactions. Here we showed that Chinese participants' implicit attitudes toward White people bias their perception and judgment of emotional intensity of White people's facial expressions such as anger, fear and sadness. We found that Chinese participants held pro-Chinese/anti-White implicit biases that were assessed in an evaluative implicit association test (IAT). Moreover, their implicit biases positively predicted the perceived intensity...

Data from: Impact on offspring methylation patterns of maternal gestational diabetes mellitus and intrauterine growth restraint suggest common genes and pathways linked to subsequent type 2 diabetes risk

Size at birth, postnatal weight gain, and adult risk for type 2 diabetes may reflect environmental exposures during developmental plasticity and may be mediated by epigenetics. Both low birth weight (BW), as a marker of fetal growth restraint, and high birth weight (BW), especially after gestational diabetes mellitus (GDM), have been linked to increased risk of adult type 2 diabetes. We assessed DNA methylation patterns using a bead chip in cord blood samples from infants...

Data from: The gravity of pollination: integrating at-site features into spatial analysis of contemporary pollen movement.

Michelle F. DiLeo, Jenna C. Siu, Matthew K. Rhodes, Adriana López-Villalobos, Angela Redwine, Kelly Ksiazek & Rodney J. Dyer
Pollen-mediated gene flow is a major driver of spatial genetic structure in plant populations. Both individual plant characteristics and site-specific features of the landscape can modify the perceived attractiveness of plants to their pollinators and thus play an important role in shaping spatial genetic variation. Most studies of landscape-level genetic connectivity in plants have focused on the effects of inter-individual distance using spatial and increasingly ecological separation; yet have not incorporated individual plant characteristics or...

Data from: Defining the alloreactive T cell repertoire using high-throughput sequencing of mixed lymphocyte reaction culture

Ryan O. Emerson, James M. Mathew, Iwona M. Konieczna, Harlan S. Robins & Joseph R. Leventhal
The cellular immune response is the most important mediator of allograft rejection and is a major barrier to transplant tolerance. Delineation of the depth and breadth of the alloreactive T cell repertoire and subsequent application of the technology to the clinic may improve patient outcomes. As a first step toward this, we have used MLR and high-throughput sequencing to characterize the alloreactive T cell repertoire in healthy adults at baseline and 3 months later. Our...

Data from: Quantitative analysis of long-form aromatase mRNA in the male and female rat brain

Nino Tabatadze, Satoru M. Sato & Catherine S. Woolley
In vitro studies show that estrogens acutely modulate synaptic function in both sexes. These acute effects may be mediated in vivo by estrogens synthesized within the brain, which could fluctuate more rapidly than circulating estrogens. For this to be the case, brain regions that respond acutely to estrogens should be capable of synthesizing them. To investigate this question, we used quantitative real-time PCR to measure expression of mRNA for the estrogen-synthesizing enzyme, aromatase, in different...

Data from: The Red Death meets the abdominal bristle: polygenic mutation for susceptibility to a bacterial pathogen in Caenorhabditis elegans

Veronique Etienne, Erik C. Andersen, José Miguel Ponciano, Dustin Blanton, Analucia Cadavid, Joanna Joyner-Matos, Chikako Matsuba, Brandon Tabman & Charles F. Baer
Understanding the genetic basis of susceptibility to pathogens is an important goal of medicine and of evolutionary biology. A key first step toward understanding the genetics and evolution of any phenotypic trait is characterizing the role of mutation. However, the rate at which mutation introduces genetic variance for pathogen susceptibility in any organism is essentially unknown. Here we quantify the per-generation input of genetic variance by mutation (VM) for susceptibility of Caenorhabditis elegans to the...

Data from: The Caenorhabditis elegans Myc-Mondo/Mad complexes integrate diverse longevity signals

David W. Johnson, Jesse R. Llop, Sara F. Farrell, Jie Yuan, Lindsay R. Stolzenburg & Andrew Vaughn Samuelson
The Myc family of transcription factors regulates a variety of biological processes, including the cell cycle, growth, proliferation, metabolism, and apoptosis. In Caenorhabditis elegans, the “Myc interaction network” consists of two opposing heterodimeric complexes with antagonistic functions in transcriptional control: the Myc-Mondo:Mlx transcriptional activation complex and the Mad:Max transcriptional repression complex. In C. elegans, Mondo, Mlx, Mad, and Max are encoded by mml-1, mxl-2, mdl-1, and mxl-1, respectively. Here we show a similar antagonistic role...
