Gene expression analysis of the ovary of hybrid females of Xenopus laevis and X. muelleriJohn H Malone
Department of Biology, The University of Texas Arlington, Box 19498, Arlington, Texas, 76010, USA
BMC Evol Biol 8:82. 2008..muelleri). In this work, we examine the gene expression pattern in hybrid females of X. laevis x X. muelleri to determine if this asymmetrical pattern of expression also occurs in hybrid females...
The genomic 'inner fish' and a regulatory enigma in the vertebratesJohn Malone
Laboratory of Cellular and Developmental Biology, National Institute of Diabetes and Digestive and Kidney Diseases, Bethesda, MD 20892, USA
J Biol 8:32. 2009..It reveals a core set of genes with similar tissue-expression patterns yet no common regulatory signatures--a gene-expression paradox...
Patterns of reproductive isolation in toadsJohn H Malone
Department of Biology, The University of Texas at Arlington, Arlington, Texas, United States of America
PLoS ONE 3:e3900. 2008..We discuss explanations for these patterns, including the role of Haldane's rule in toads and anurans in general, and suggest mechanisms generating patterns of reproductive isolation in anurans...
Microarrays, deep sequencing and the true measure of the transcriptomeJohn H Malone
Laboratory of Cellular and Developmental Biology, National Institute of Digestive, Diabetes, and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892, USA
BMC Biol 9:34. 2011..We conclude that microarrays remain useful and accurate tools for measuring expression levels, and RNA-Seq complements and extends microarray measurements...
Germline-dependent gene expression in distant non-gonadal somatic tissues of DrosophilaMichael J Parisi
Department of Biology, University of Pennsylvania, Philadelphia, PA, USA
BMC Genomics 11:346. 2010..We know little about the coordinated regulation of gene expression patterns in distant somatic tissues that support the developmental cost of gamete production...
Physiological sex predicts hybrid sterility regardless of genotypeJohn H Malone
Department of Biology, University of Texas at Arlington, Box 19498, Arlington, TX 76019, USA
Science 319:59. 2008..Gene expression profiles match these adult phenotypes, and our results demonstrate that faster-male evolution is the most likely mechanism producing hybrid male sterility...
Sterility and gene expression in hybrid males of Xenopus laevis and X. muelleriJohn H Malone
Department of Biology, The University of Texas at Arlington, Arlington, Texas, United States of America
PLoS ONE 2:e781. 2007..muelleri)...
Gene expression polymorphism in Drosophila populationsPawel Michalak
Department of Biology, University of Texas at Arlington, Arlington, TX 76019 0498, USA
Mol Ecol 16:1179-89. 2007..melanogaster/races/strains and predicted to be translational-inactive in Cosmopolitan due to a major deletion, was found to be up-regulated in Zimbabwe and down-regulated, but still expressed, in Cosmopolitan...
Expression in aneuploid Drosophila S2 cellsYu Zhang
Laboratory of Cellular and Developmental Biology, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, Maryland, United States of America
PLoS Biol 8:e1000320. 2010..Our data indicate that expression dosage compensation dampens the effect of altered DNA copy number genome-wide. For the X chromosome, compensation includes fixed and dose-dependent components...
Testis-derived microRNA profiles of African clawed frogs (Xenopus) and their sterile hybridsPawel Michalak
Department of Biology, University of Texas Arlington, Box 19498, Arlington, TX 76019, USA
Genomics 91:158-64. 2008..A number of candidate differential microRNAs from this study have previously been described as testis-specific in the mouse, suggesting that microRNA structural conservation may be associated with functional retention...
The sex chromosome that refused to dieJohn H Malone
Laboratory of Cellular and Developmental Biology, National Institute of Diabetes, Digestive, and Kidney Diseases, National Institutes of Health, Department of Health and Human Services, Bethesda, MD 20892, USA
Bioessays 30:409-11. 2008..melanogaster genome.1 These results show that variation on Y has an important influence on the deployment of the genome...
Mediation of Drosophila autosomal dosage effects and compensation by network interactionsJohn H Malone
Laboratory of Cellular and Developmental Biology, National Institute of Diabetes and Digestive and Kidney Diseases, 50 South Drive, Bethesda, MD 20892, USA
Genome Biol 13:r28. 2012..While it is often assumed that reducing gene dose by half leads to two-fold less expression, there is partial autosomal dosage compensation in Drosophila, which may be mediated by feedback or buffering in expression networks...
Sex-biased gene expression in a ZW sex determination systemJohn H Malone
Department of Biology, The University of Texas--Arlington, Box 19498, Arlington, TX 76019, USA
J Mol Evol 63:427-36. 2006....
