This question is best addressed in a genetic mapping population in which all molecular polymorphisms are known and for which molecular endophenotypes and complex traits are assessed on the same genotypes. Here, we performed deep RNA sequencing of 200 Drosophila Genetic Reference Panel inbred lines with complete genome sequences and for which phenotypes of many quantitative traits have been evaluated. We mapped expression quantitative trait loci for annotated genes, novel transcribed regions, transposable elements, and microbial species. We identified host variants that affect expression of transposable elements, independent of their copy number, as well as microbiome composition. We constructed sex-specific expression quantitative trait locus regulatory networks. These networks are enriched for novel transcribed regions and target genes in heterochromatin and euchromatic regions of reduced recombination, as well as genes regulating transposable element expression. This study provides new insights regarding the role of natural genetic variation in regulating gene expression and generates testable hypotheses for future functional analyses.}, number={3}, journal={GENOME RESEARCH}, author={Everett, Logan J. and Huang, Wen and Zhou, Shanshan and Carbone, Mary Anna and Lyman, Richard F. and Arya, Gunjan H. and Geisz, Matthew S. and Ma, Junwu and Morgante, Fabio and St Armour, Genevieve and et al.}, year={2020}, month={Mar}, pages={485–496} } @article{gabrawy_campbell_carbone_morozova_arya_turlapati_walston_starz-gaiano_everett_mackay_et al._2019, title={Lisinopril Preserves Physical Resilience and Extends Life Span in a Genotype-Specific Manner in Drosophila melanogaster}, volume={74}, ISSN={["1758-535X"]}, DOI={10.1093/gerona/glz152}, abstractNote={Abstract Physical resiliency declines with age and comorbid conditions. In humans, angiotensin-converting enzyme (ACE) has been associated with attenuation of the decline in physical performance with age. ACE-inhibitor compounds, commonly prescribed for hypertension, often have beneficial effects on physical performance however the generality of these effects are unclear. Here, we tested the effects of the ACE-inhibitor Lisinopril on life span, and age-specific speed, endurance, and strength using three genotypes of the Drosophila melanogaster Genetic Reference Panel. We show that age-related decline in physical performance and survivorship varies with genetic background. Lisinopril treatment increased mean life span in all Drosophila Genetic Reference Panel lines, but its effects on life span, speed, endurance, and strength depended on genotype. We show that genotypes with increased physical performance on Lisinopril treatment experienced reduced age-related protein aggregation in muscle. Knockdown of skeletal muscle-specific Ance, the Drosophila ortholog of ACE, abolished the effects of Lisinopril on life span, implying a role for skeletal muscle Ance in survivorship. Using transcriptome profiling, we identified genes involved in stress response that showed expression changes associated with genotype and age-dependent responsiveness to Lisinopril. Our results demonstrate that Ance is involved in physical decline and demonstrate genetic variation in phenotypic responses to an ACE inhibitor.}, number={12}, journal={JOURNALS OF GERONTOLOGY SERIES A-BIOLOGICAL SCIENCES AND MEDICAL SCIENCES}, author={Gabrawy, Mariann M. and Campbell, Sarah and Carbone, Mary Anna and Morozova, Tatiana V and Arya, Gunjan H. and Turlapati, Lavanya B. and Walston, Jeremy D. and Starz-Gaiano, Michelle and Everett, Logan and Mackay, Trudy F.

Taking the position that resistance is nearly inevitable, we undertook a study to identify and exploit targetable vulnerabilities that were manifest in endocrine therapy-resistant disease. Using cellular and mouse models of endocrine therapy-sensitive and endocrine therapy-resistant breast cancer, together with contemporary discovery platforms, we identified a targetable pathway that is composed of the transcription factors FOXA1 and GRHL2, a coregulated target gene, the membrane receptor LYPD3, and the LYPD3 ligand, AGR2. Inhibition of the activity of this pathway using blocking antibodies directed against LYPD3 or AGR2 inhibits the growth of endocrine therapy-resistant tumors in mice, providing the rationale for near-term clinical development of humanized antibodies directed against these proteins.}, number={4}, journal={CELL REPORTS}, author={Cocce, Kimberly J. and Jasper, Jeff S. and Desautels, Taylor K. and Everett, Logan and Wardell, Suzanne and Westerling, Thomas and Baldi, Robert and Wright, Tricia M. and Tavares, Kendall and Yllanes, Alex and et al.}, year={2019}, month={Oct}, pages={889-+} } @article{garlapow_everett_zhou_gearhart_fay_huang_morozova_arya_turlapati_st armour_et al., title={Genetic and genomic response to selection for food consumption in Drosophila melanogaster}, volume={47}, number={2}, journal={Behavior Genetics}, author={Garlapow, M.
