Project description:Male and female rats received daily injections of saline or methamphetamine for 10 days. Changes in gene expression were assessed by RNA sequencing either 24 hours or 30 days following the last injection. Methamphetamine induced changes in the myocardial transcriptome were significantly greater in female hearts than male hearts both in terms of the number of genes affected and the magnitude of the changes. The largest changes in female hearts involved genes that regulate the circadian clock (Dbp, Per3, Per2, BMal1, and Npas2) which is known to impact myocardial sensitivity to ischemia. These genes were unaffected by methamphetamine in male hearts. All changes in gene expression identified at day 11 returned to baseline by day 30. These data demonstrate that female rats are more sensitive than males to methamphetamine-induced changes in the myocardial transcriptome and that methamphetamine does not induce changes in myocardial transcription that persist long term after exposure to the drug has been discontinued.

Project description:Purpose: The goals of this study are to compare E9.5 male and female C57 mouse embryonic hearts transcriptome profiling (RNA-seq) to conclude cardiac sex differences at the mRNA level. Methods: mRNA profiles of E9.5 male and female C57 mouse embryonic hearts were generated by deep sequencing, n=4 for each sex, using Illumina HiSeq2500. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. Results: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to the mouse genome (build mm10) and identified 16,460 transcripts in the mouse hearts.

Project description:Purpose: The goals of this study are to compare adult male and female C57 mouse hearts transcriptome profiling (RNA-seq) to conclude cardiac sex differences at the mRNA level. Methods: mRNA profiles of adult male and female C57 mouse hearts were generated by deep sequencing, n=4 for each sex, using Illumina HiSeq2500. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. Results: Using an optimized data analysis workflow, we mapped about 50 million sequence reads per sample to the mouse genome (build mm10) and identified 16,160 transcripts in the mouse hearts.

Project description:Substance use disorder (SUD) is a chronic neuropsychiatric condition characterized by long-lasting alterations in the neural circuitry regulating reward and motivation. Substantial work has focused on characterizing the molecular substrates which underlie these persistent changes in neural function and behavior; however, this work has overwhelmingly focused on male subjects, despite mounting clinical and preclinical evidence that females demonstrate dissimilar progression to SUD and responsivity to drugs of abuse, such as cocaine. Here, we show that sex is a critical biological variable that defines drug-induced plasticity in the NAc. Using quantitative mass spectrometry, we assessed the protein expression patterns altered by cocaine self-administration and demonstrate unique molecular profiles between males and females. We show that 1. Cocaine self-administration induces non-overlapping protein expression patterns in males and females and 2. Cocaine specifically acts on baseline sexual dimorphisms to exert these effects. Critically, we find that cocaine administration blunts not only basal sex-differences in the accumbens proteome, but also the pre-existing sex differences in behavior for natural rewards. Together, these data suggest that chronic cocaine is capable of rewriting baseline proteomic function to maintain cocaine-specific behaviors.

Project description:Methamphetamine can trigger dopamine releasing in human brain, now used as abuse drug. Some studies have shown that specific genes and proteins responded to, methamphetamine, but little is known about the overall “omic” response of organisms to this illicit substance. Here we demonstrate that Drosophila melanogaster has the potential to give us significant insights into evolutionarily conserved responses to methamphetamine. We performed metabolome, proteome, and transciptome profiling with Drosophila treated with methamphetamine. The proteomic profiling revealed responses associated with known physiological problems that occur with methamphetamine usage in mammals. The metabolomic result showed that the metabolite trehalose was decreased significantly after methamphetamine exposure, suggesting an oxidative stress response to this drug. Many of the differential transcribed genes, including detoxification enzymes, had the potential transcription factor-binding motif YY1 associated with their upstream regulatory regions. YY1 is known to be responsive to amphetamines in mammals.

Project description:We sought to investigate the scope of cellular and molecular changes within a mouse’s olfactory system as a function of its exposure to odors emitted from members of the opposite sex. To this end, we housed mice either separated from members of the opposite sex (sex-separated) or together with members of the opposite sex (sex-combined) until six months of age and then profiled transcript levels within the main olfactory epithelium (MOE), vomeronasal organ (VNO), and olfactory bulb (OB) of the mice via RNA-seq. For each tissue type, we then analyzed gene expression differences between sex-separated males and sex-separated females (SM v SF), sex-combined males and sex-combined females (CM v CF), sex-separated females and sex-combined females (SF v CF), and sex-separated males and sex-combined males (SM v CM). Within both the MOE and VNO, we observed significantly more numerous gene expression differences between males and females when mice were sex-separated as compared to sex-combined. Chemoreceptors were highly enriched among the genes differentially expressed between males and females in sex-separated conditions, and these expression differences were found to reflect differences in the abundance of the corresponding sensory neurons.

Project description:We performed RNA sequencing to characterize the effects of methamphetamine on HIV-infected mature monocytes. In vitro cultured HIV-infected mature (CD14+ CD16+) monocytes were treated with and without methamphetamine for 6h. RNA was extracted, sequenced, and analyzed for differential gene expression.

Project description:The study is relevant to an understanding of the forces that lead to sex differences in the brain and other somatic tissues. Many neural and psychiatric diseases affect men and women differently, so the understanding of sex differences in brain function impacts on our understanding of why the male and female brain differ in their susceptibility to disease. Using Affymetrix chicken arrays, we will measure the gene expression in male and female embryonic chicken heart, and compare to previous studies of brain and liver. Gene expression differs in the male and female embryonic chicken heart, liver, and brain. Higher expression of Z-chromosome genes in males is found in heart, liver and brain. Comparison of heart and brain will reveal brain-specific patterns of sex differences, and patterns that apply to multiple tissues. 20 male and 20 female chicken embryos will serve as source of heart tissue. In late stage embryos, we will remove the tissue and extract total RNA. Four birds will comprise each individual sample. Thus, we will have 5 biologically independent male samples, and an equal number of female samples. Keywords: dose response
