TranscriptomicsGene expression variation in Y-chromosome substitution lines of Drosophila melanogaster
These arrays were done in the context of a study to probe gene expression variation across Y-chromosome substitution lines of Drosophila melanogaster Keywords: polymorphism, evolution, chromosome substitution This series contains all the arrays and designs described in Lemos et al.

TranscriptomicsDrosophila melanosgaster 2nd chromosome substitution lines
Transcriptional profiling of Drosophila melanogaster 2nd chromosome substitution lines; Background chromosomes are identical across lines; 2nd chromosomes are different across line and can be homozygous or heterozygous within each line Keywords: Natural variation Loop design with 8 genotypes

TranscriptomicsHigh intake of dietary sugar enhances bisphenol A (BPA) disruption and reveals ribosome-mediated pathways of toxicity: Acute Exposure
Fly strain y[1]; bw[1]; e[4]; ci[1] ey[R] was obtained from the Bloomington Stock Center. Flies were reared in incubators at 25°C, 65% of relative humidity, and photoperiod of 12 hours. For gene expression analyses flies were exposed to BPA, DEHP, and high sugar for 48 hours (acute exposure). After ...

TranscriptomicsHigh intake of dietary sugar enhances bisphenol A (BPA) disruption and reveals ribosome-mediated pathways of toxicity: Chronic Exposure
Fly strain y[1]; bw[1]; e[4]; ci[1] ey[R] was obtained from the Bloomington Stock Center. Flies were reared in incubators at 25°C, 65% of relative humidity, and photoperiod of 12 hours. For gene expression analyses flies were reared in media containing BPA, high sugar, and BPA + high sugar (chronic ...

TranscriptomicsGene expression variation in Y-substitution lines in different genetic backgrounds of Drosophila melanogaster
We studied Y chromosomes from two geographically diverse populations of Drosophila melanogaster, and show that these Y chromosomes differentially modify the expression of hundreds of autosomal and X-linked genes. Genes showing Y-linked regulatory variation also show an association with immune respon...

TranscriptomicsCopy number variation: the balance between gene dosage and expression in Drosophila melanogaster
Copy number variants (CNVs) reshape gene structure, modulate gene expression, and contribute to significant phenotypic variation. Previous studies have revealed CNV patterns in natural populations of Drosophila melanogaster and suggested that selection and mutational bias shape genomic patterns of C...

TranscriptomicsVariable D. melanogaster Y chromosomes into the genetic background JIL-1/+, Mod(mdg4)/+, and Su(var)205/+.
Fly strains were obtained from the Bloomington Stock Center. The chromosomes containing the gene deletion mod(mdg4)L3101 {y[1] w[1118]; P{w[+mC]=lacW}mod(mdg4)[L3101]/TM3, Ser[1]}, HP1 {In(1)w[m4h]; Su(var)205[5]/In(2L)Cy,In(2R)Cy, Cy[1]}, mod(mdg4)G16853 {w[1118]; P{w[+mC]=EP}mod(mdg4)[G16853]/TM6C...

TranscriptomicsSex chromosome parent-of-origin effects on gene expression in Drosophila melanogaster
RNA was extracted from adult male and adult female Drosophila melanogaster with reversed sex-chromosome parent-of-origin (e.g. maternal-X/paternal-Y vs. paternal-X/maternal-Y) Parent-of-origin effects were assayed in X/Y males, XY/Y males, and XY/X females. Direct comparisons were made between indi...
