(Submitter supplied) Opioid abuse produces enduring associations between the drug euphoria and features of the drug-taking experience, and these powerful associations can trigger relapse in individuals recovering from opioid use disorder. We show here that the epigenetic enzyme, histone deacetylase 5 (HDAC5), functions in the nucleus accumbens (NAc) during active heroin use to limit future relapse-like behavior. Moreover, enhancing HDAC5 function in NAc dramatically suppresses context-associated and reinstated heroin seeking behaviors, but it does not impact sucrose seeking. more...

(Submitter supplied) Germinal centers (GCs) are the site of immunoglobulin somatic hypermutation and affinity maturation, processes essential to an effective antibody response. The formation of GCs has been studied in detail, but less is known about what leads to their regression and eventual termination, factors that ultimately limit the extent to which antibodies mature within a single reaction. We show that contraction of immunization-induced GCs is immediately preceded by an acute surge in GC-resident Foxp3+ T cells, attributed at least partly to upregulation of the transcription factor Foxp3 by T follicular helper (Tfh) cells. more...

(Submitter supplied) Galanin neurons at ventrolateral preoptic nuleus (VLPO) have been hypothesized to be sleep-active neurons. With the use of laser capture microdissection (LCM), we specifically isolated single galanin neurons, and our goal was to assess expression changes in VLPO galanin cells between sleeping mice and mice kept awake using gentle handling.

(Submitter supplied) Adhesion of T. cruzi trypomastigotes to components of the extracellular matrix (ECM) is an important step in mammalian host cell invasion. We have recently described a significant increase in the tyrosine nitration levels of histones H2A and H4 when trypomastigotes are incubated with components of the ECM. In this work, we used chromatin immunoprecipitation (ChIP) with an anti-nitro-tyrosine antibody followed by mass spectrometry to identify nitrated DNA binding proteins in T. more...

(Submitter supplied) Sleep abnormalities are common with aging. Studies show that sleep plays important roles in brain functions, and loss of sleep is associated with increased risks for neurological diseases. In this study, we used next generation RNA-sequencing to explore effects of age on transcriptome changes between sleep and sleep deprivation in medial prefrontal cortex. Old mice showed a 30% reduction in the number of genes significantly altered between sleep/wake, and, in general, had smaller magnitudes of changes in differentially expressed genes compared to young. more...

(Submitter supplied) This SuperSeries is composed of the SubSeries listed below. A valuable approach to understand how individual and population genetic differences can predispose to disease is to assess the impact of genetic variants on cellular functions (e.g., gene expression) of cell and tissue types related to pathological states. To understand the genetic basis of nonsyndromic cleft lip with or without cleft palate (NSCL/P) susceptibility, a complex and highly prevalent congenital malformation, we searched for genetic variants with a regulatory role in a disease-related tissue, the lip muscle (orbicularis oris muscle [OOM]), of affected individuals. more...

(Submitter supplied) The conserved RNA-binding protein Musashi1 (MSI1) has emerged as a key oncogenic factor in numerous solid tumors, including glioblastoma. However, its mechanism of action has not yet been established comprehensively. We set out to map its impact on the transcriptome in U251 cells using RNA-seq and iCLIP.

(Submitter supplied) Precise regulation of transduction signaling pathways genes is crucial for correct differentiation of kidney cells and perturbation may lead to tumor onset. Wilms tumors (WT), or nephroblastoma, originates from the metanephric blastema cells, which were unable to complete the differentiation, resulting in a triphasic tumor composed by distinct cell types, blastemal, epithelial and stromal, where the former harbor molecular characteristics similar to cells of the earliest stages of kidney development. more...

(Submitter supplied) The etiology of trauma-hemorrhage shock-induced acute lung injury has been difficult to elucidate due, at least in part, to the inability of in vivo studies to separate the non-injurious pulmonary effects of trauma-hemorrhage from the tissue injurious ones. To circumvent this in vivo limitation, we utilized a model of trauma-hemorrhagic shock (T/HS) in which T/HS-lung injury was abrogated by dividing the mesenteric lymph duct. more...
