The Drosophila genome is organized by 2 types of elements: tethers mediate focal contacts, while insulators establish #TAD boundaries. We used genome editing and live transcription imaging to explore their roles in the temporal regulation of #Hox gene expression in the embryo. 
Transcription of the endogenous Scr gene, live! Active transcription foci (white spots) appear in a narrow stripe of nuclei (blue) just prior to the onset of gastrulation. (Scr-MS2, MCP-GFP, His2A-RFP)
Please enjoy our new #preprint, "High-throughput discovery and characterization of human transcriptional effectors"! 😀
We tested thousands of protein domains and mutants for the ability to repress/activate #GeneExpression and ID effectors in 600 proteins

For many human #TranscriptionFactors & #chromatin regulators, we know more about *where* they bind than *how* they regulate expression
To find effector domains in an unbiased way, we tested a library of the majority of nuclear protein domains with our new method, HT-recruit

We find hundreds of human #repressor domains, including several domains of unknown function
Excited to announce my first first-author publication (ever!) from my PhD is now online!!!! Co-first author with the amazing @Rafiqi51. Directed by @ehab_abouheif The Great @AbouheifLab. @BioMcGill @mcgillu @EvoDevoPanAm Want to know more? [A THREAD]

Developmental biology textbooks were of no use when the #segmentationhierarchy was #shook with #hoxgenes unleashed and the #fusion of highly conserved gene regulatory networks! #2germlines and an #embryo that gives humpty dumpty a run for his money. #CamponotusFloridanus 3/n
We’re proud to present our #preprint, where we induce embryo-like morphogenesis in #gastruloids, resulting in the generation of trunk-like-structures (#TLS) with #somites flanking the #neuraltube @MPI_MolGen w/ @adrianobolondi . A short summary (1/12) biorxiv.org/content/10.110…
#Gastruloids are a fantastic culture system, but lack proper morphogenesis, e.g. neural cells do not form a neural tube and presomitic mesoderm does not condense into somites. Can we induce proper embryo-like morphology by mechano-chemical manipulation? Yes, we can! (2/12)
Embedding 96h #gastruloids in 5% #matrigel resulted in trunk-like-structures, with somites flanking the neural tube. Activation of WNT signaling, either alone or in combination with BMP inhibition lead to hyper-epithelialized somites arranged as a bunch of grapes (3/12)
