Data from: Loss of murine Paneth cell function alters the immature intestinal microbiome and mimics changes seen in neonatal necrotizing enterocolitis

Necrotizing enterocolitis (NEC) remains the leading cause of gastrointestinal morbidity and mortality in premature infants. Human and animal studies suggest a role for Paneth cells in NEC pathogenesis. Paneth cells play critical roles in host-microbial interactions and epithelial homeostasis. The ramifications of eliminating Paneth cell function on the immature host-microbial axis remains incomplete. Paneth cell function was depleted in the immature murine intestine using chemical and genetic models, which resulted in intestinal injury consistent with...

Data from: Bio-inspired imager improves sensitivity in near-infrared fluorescence image-guided surgery

Image-guided surgery can enhance cancer treatment by decreasing, and ideally eliminating, positive tumor margins and iatrogenic damage to healthy tissue. Current state-of-the-art near-infrared fluorescence imaging systems are bulky and costly, lack sensitivity under surgical illumination, and lack co-registration accuracy between multimodal images. As a result, an overwhelming majority of physicians still rely on their unaided eyes and palpation as the primary sensing modalities for distinguishing cancerous from healthy tissue. Here we introduce an innovative design,...

Data from: Expression of and choice for condition-dependent carotenoid-based color in an urbanizing context

Mathieu Giraudeau, Matthew B. Toomey, Pierce Hutton & Kevin J. McGraw
Urban environments create a unique suite of conditions, leading to changes in animal behavior, morphology, phenology or physiology. Condition-dependent traits such as the carotenoid-based coloration offer a unique opportunity to assess the impacts of urbanization on organisms because they reflect the nutrition, health or other resource-based attributes of their bearers and they play an essential role in intra- and inter-sex interactions. To determine if and how the carotenoid-based coloration of male house finches (Haemorhous mexicanus)...

Data from: A non-coding region near Follistatin controls head colour polymorphism in the Gouldian finch

Matthew B. Toomey, Cristiana I. Marques, Pedro Andrade, Pedro Miguel Ara├║jo, Stephen Sabatino, Malgorzata A. Gazda, Sandra Afonso, Ricardo J. Lopes, Joseph C. Corbo & Miguel Carneiro
Discrete color morphs coexisting within a single population are common in nature. In a broad range of organisms, sympatric color morphs often display major differences in other traits, including morphology, physiology, or behavior. Despite the repeated occurrence of this phenomenon, our understanding of the genetics that underlie multi-trait differences and the factors that promote the long-term maintenance of phenotypic variability within a freely interbreeding population are incomplete. Here, we investigated the genetic basis of red...

Data from: Validation of diffusion tensor imaging measures of nigrostriatal neurons in macaques

Objective: Interpretation of diffusion MRI in the living brain requires validation against gold standard histological measures. We compared diffusion values of the nigrostriatal tract to PET and histological results in non-human primates (NHPs) with varying degrees of unilateral nigrostriatal injury induced by MPTP, a toxin selective for dopaminergic neurons. Methods: Sixteen NHPs had MRI and PET scans of three different presynaptic radioligands and blinded video-based motor ratings before and after unilateral carotid artery infusion of...

Data from: Identification of a transporter complex responsible for the cytosolic entry of nitrogen-containing-bisphosphonates

Nitrogen-containing-bisphosphonates (N-BPs) are widely prescribed to treat osteoporosis and other bone-related diseases. Although previous studies established that N-BPs function by inhibiting the mevalonate pathway in osteoclasts, the mechanism by which N-BPs enter the cytosol from the extracellular space to reach their molecular target is not understood. Here we implemented a CRISPRi-mediated genome-wide screen and identified SLC37A3 (solute carrier family 37 member A3) as a gene required for the action of N-BPs in mammalian cells. We...

Data from: An integrated data resource for genomic analysis of cutaneous T-cell lymphoma

Li-Wei Chang, Larisa J. Geskin, Christina Chung Patrone, Fernando Gallardo, Blanca Espinet, Cornelis P. Tensen, Maarten Vermeer, Wei Yang & Michael Girardi
Recently, several groups have conducted sequencing studies of cutaneous T-cell lymphoma (CTCL) in order to identify disease driving mutations. An integrated genomic dataset that combines multiple cohorts may facilitate more comprehensive studies of disease pathways and genomic classification of CTCL, but currently no such resource is available. In this study we compiled and analyzed one such dataset that included matched genomic mutations and copy number alterations of 139 CTCL cases. Using this dataset, we studied...
