Garat is in the lab of Jose Sotelo, which has been collaborating with George Bloom at the University of Virginia for several years on a study of Alzheimer’s disease’s effects on protein synthesis. Garat will extend that work in the Bloom lab. “This opportunity will allow me to work with excellent investigators and to use transgenic animal models that are not available in my country,” Garat said. “During my stay, we plan to work on single-cell Ribo-seq protocols in collaboration with Guillermo Eastman, a postdoc at Bloom´s lab, that will allow the study of translation regulation heterogeneity between different cell types in health and disease.”
Geovana S. Garcia
Project title: The biochemical basis of the growth induced by the xenotopic expression of the mitochondrial alternative oxidase in Drosophila larva
Geovana S. Garcia is a Ph.D. candidate at São Paulo State University’s Jaboticabal campus in Brazil. She’s working on a thesis about mitochondrial alternative oxidase expression in Drosophila in the lab of Marcos T. Oliveira, with whom Garcia first began working as an undergrad. Garcia will be hosted by Jason Tennessen’s lab at Indiana University Bloomington. The lab uses the fruit fly to study metabolism, physiology and development. “My research proposal aims to evaluate how the xenotopic expression of mitochondrial alternative oxidase — AOX, an enzyme with therapeutic potential — modulates larval growth in a metabolic level,” Garcia said. “In Tennessen’s lab, I will have technology available to quantify key metabolites and hormones in diverse larvae expressing AOX, aggregating our understanding of larval growth and metabolic basis of tumors. I will have the opportunity to work in the same building as Bloomington Drosophila Stock Center, one of the largest providers of stocks for fly research in the world. My academic career will be incredibly impacted by this opportunity.”

Project title: Zika virus infection modulates translation of cellular antiviral factors
Horacio Martín Pallarés is a Ph.D. student at the Leloir Institute Foundation in Argentina. He’s studying the mechanisms of Zika virus replication and viral immune system evasion processes in the lab of Andrea Gamarnik. Zika virus belongs to the Flaviviridae family, which includes a large number of emerging and re-emerging human pathogens that cause fever and encephalitis, such as West Nile virus, Japanese encephalitis virus and dengue virus. A Zika outbreak in the Americas and its suspected link to microcephaly put this virus at the forefront of an international research effort to understand its replication strategies and pathogenesis. Pallarés will spend time in the lab of Ariel Bazzini at the Stowers Institute for Medical Research. While in Kansas City, Missouri, he plans to use ribosome profiling and RNA sequencing to study how Zika virus regulates host gene expression. “I’m very excited about the PROLAB travel award. This is an invaluable opportunity for me! It will be crucial for my thesis project, and it will allow me to acquire new skills in techniques that are poorly developed in Argentina,” Pallarés said.
