Lab News

October 2022   Open positions: Newly in Hohenheim, we have positions available for a postdoc and a Ph.D. student, from early 2023.
This is very open-ended, for projects that fit the breadth of the Panfilio Lab's interests: from epithelial tissue biology, genetics of cell physiology, and fluorescence microscopy to molecular evolution, eco-evo, and insect comparative genomics. Spread the word, and/or get in touch directly (k.panfilio @ with any questions or to discuss potential projects in detail. Formal advertisements will be posted soon - stay tuned!
The Extraembryonic Tissues theme issue is now out! Our comparative review on EE tissue biology across amniote vertebrates and insects, with Susana Chuva de Sousa Lopes, features side-by-side comparisons of the bug, beetle, chick, human, and mouse. We address parallels in anatomy, morphogenesis, gene expression and function, polyploidy, and eco-devo roles.  
September 2022  
Inspired by the GfE meeting, Kristen finally succumbed and joined Twitter: personal musings and announcements @KAPanfilio (on my own behalf, not of the entire lab)!    
    Autumn meeting: As a great welcome to our new lab home, the biennial meeting of the German Society for Developmental Biology (GfE) is a local event in Hohenheim, including an invited talk by Kristen.
    Article featured: Our paper on dsRNA uptake during parental RNAi from empirical and phylogenomic perspectives is featured with the cover image of the September issue of Advanced Genetics and with a companion Research News article on Advanced Science News.
    Lab international transition, Part 2: Kristen joins the University of Hohenheim in Stuttgart, Germany, as the new Professor for Molecular Genetics!
Much to learn to keep the running system going in our department for research and teaching, even as we start to beetle-ify the lab (Notch pathway and genome stability in Drosophila meets evolutionary developmental genetics/genomics/morphogenesis in beetles and bugs).
August 2022   Lab international transition, Part 1: Kristen transitions from Reader to Honorary Professorial Fellow (guest scientist) status in Warwick, even as the team's research steams ahead in situ with Poornima's FACS and Will's eRNAi experiments...
July 2022   Summer meeting: Two years later, the '2020' International Congress of Entomology meeting takes place in person in Helsinki, with a talk by Kristen on current considerations with analyzing insect genome data.
    As Reviews Editor at Development, Genes and Evolution, Kristen pens an eco-evo-devo editorial to showcase a new review on striking features of aphid developmental genetics from Chun-che Chang and colleagues, encompassing viviparity, plasticity, patterning, the germline, and bacterial endosymbionts.
June 2022  
Image featured: One of the fluorescent images from our recent study on the mechanisms of parental RNAi is featured in the latest "Science in Pictures" collection from Wiley's Advanced Science News.  
May 2022   Congratulations to Eden Coetzer and Olivia Boucher on their symposium presentations and submitting their MBio theses, reflecting the culmination of their research projects in the lab this academic year. The social culmination was a very convivial lab pub lunch!
    Welcome to this year's bachelor's mini-project research students, who now begin the main analysis period of their diverse projects on the genetic regulation of epithelial tissue maturation and morphogenesis: Abi Hicks, Emily Sanderson, Narmin Sirdi, Juliana Jeyakumar, Adele Sandrone, and Swathi Krishnakumar.
April 2022   Spring meetings, II., in-person conference attendance: Kristen and Poornima attend the annual Spring Meeting of the British Society for Developmental Biology, held locally on the Warwick campus, with Poornima presenting a poster on her investigations to date on extraembryonic tissue polyploidy.
March 2022  
Paper accepted: On the first day of spring, our study on the mechanism of parental RNAi in Tribolium debuts in the new journal Advanced Genetics. This tripartite study shows that long dsRNA originally injected into the mother is directly transmitted into eggs, and yet -- without dsRNA amplification -- strain-specific knockdown can last for months. Furthermore, phylogenomic profiling reveals multiple losses of the dsRNA importer SID-1 from arthropod genomes, notably including the true bugs (Heteroptera).  
    Spring meetings, I., armchair conference travel: the lab attends the virtual meeting "Mind the Gap: From Genotype to Phenotype and the role of Modelling, Genomic Prediction and Development", organized by the Developmental Biology Section of the German Zoological Society, with presentations on an inspiring range of research organisms and developmental traits.
    Seminar reboot: After a two-year hiatus, we relaunch the local "Animal Cell Biology and Gene Expression" data seminar series across the School of Life Sciences and Warwick Medical School, bringing together the Bowman, Hebenstreit, Nelson, Panfilio, and Pires da Silva labs for shared research interests that span our widely disparate research systems.
February 2022   Paper accepted: Having gone on quite an intellectual journey for this, Kristen's review together with Susana Chuva de Sousa Lopes is accepted for publication in the forthcoming "Extraembryonic Tissues" theme issue in the Philosophical Transactions of the Royal Society B. Planned for summer 2022, we take a first comparative look at the surprising parallels between the independently evolved extraembryonic tissues of amniote vertebrates and insects.
December 2021   During a brief ebb in the pandemic, the lab manages to enjoy a Christmas pub lunch together, followed by a secret Santa exchange. Only some of the gifts were insect- or cell biology-themed!

This represents one of the first genomic characterizations for thrips (Thysanoptera), insects with unique features such as asymmetric mouthparts and neometaboly metamorphosis, as well as being vectors of viral plant diseases.
    As a satellite to the German Zoological Society's annual meeting, the "Protostome functional genetics - Tribolium and friends" day-long session was a wonderful international gathering for arthropod evo devo and the wider community. Kudos to Gregor Bucher for scheduling across time zone gradations and for fostering really effective coffee break and break-out session discussions!
August 2020   Grant funded: Our project "Functional significance and remodeling challenges of polyploidy across the lifetime of epithelial tissues" is awarded a responsive mode grant from the BBSRC.
    Paper accepted: Danka's beautifully detailed investigation of functional divergence of the Tribolium zen paralogues is accepted for publication in Communications Biology (currently available on bioRxiv). By integrating diverse gene expression and functional data, we demonstrate that the evolutionary acquisition of reciprocal paralogue regulation promotes developmental progression and may have underpinned multiple ancestral subfunctionalization events. Long-term expression profiling also informs the transcriptional landscape of late beetle embryogenesis and characterizes physiological processes in the serosal epithelium.
July 2020
