Excited to share our new preprint on bioRxiv. 🎉 We uncovered a Wnt-induced phospho-switch of Dishevelled. This intramolecular coupling is mutually exclusive with FZD engagement and functionally required for the Wnt/β-catenin signaling. 🧵 doi.org/10.1101/2025...

Please do get in touch is you want to join our molecular and cellular biology community. Also look at out Development, Regeneration and Neurophysiology cluster, if that's a better fit: sheffield.ac.uk/biosciences/... We of course welcome people (like me!) that straddle the two

It's taken a while but final version of Alex's manuscript now out in eLife. We're proud of it – it was a difficult project with hard assays. Even the eLife editor admits it's 'useful' – and I'm not sure how often you see a genuinely useful paper these days?! elifesciences.org/articles/107...

Characterisation of cell-scale signalling by the core planar polarity pathway during Drosophila wing development

Quantitative Drosophila pupal wing experiments support planar polarity depending on cell-scale signalling that does not involve depletion of a limited pool of core proteins or polarised transport on microtubules.

Development folks: the next Northern England Developmental Biology @bsdb.bsky.social @biologists.bsky.social meeting will take place on the 10th of July in Sheffield. Great speaker line-up, cheap registration fee and plenty of slots for ECR talks. Registration deadline=31/5, see poster for details

New! 15y after the classic Aigouy et al "Cell Flow Reorients the Axis of Planar Polarity in the Wing Epithelium..." from lab of much missed Suzanne Eaton, we provide our take from post-doc Sara Tan "Tissue shear as a cue for aligning planar polarity in the developing Drosophila wing". rdcu.be/d81Vn

Now that my lab has moved to Emory I want you to join us in Atlanta. We have an NIH-funded postdoc position available to study Planar Cell Polarity (PCP) signaling using vestibular hair cells of the mouse as a model. Please repost and/or DM for details

My quote of the day (or possibly the week/month/year): ‘Building organisms is about bringing #SelfOrganization under control’ I’m going to borrow this to use in my talks

Alfonso Martinez Arias@amartinezarias.bsky.social · 2y ago

First. The potential of a gene on its own is bigger than what is revealed by its loss of function. Two. Don’t be fooled by deterministic genetic control. Underneath there is a capacity for #SelfOrganization which is the essence of biological systems. Building organisms is @ bringing SO under control

Drosophila cell culture people: we've been using Qiagen Effectene to transfect S2 cells with ~30% efficiency, but latest batch is only giving us <1% efficiency (so no use to us!!). Qiagen don't seem to have a solution. Anyone got suggestions for other (good!) fly cell culture transfection reagents?

A little pre-Christmas reading for my planar polarity follower(s) – I’m sure there’s at least one of you! The Fat-Dachsous planar polarity pathway competes with hinge contraction to orient polarized cell behaviors during Drosophila wing morphogenesis. Current Biology doi.org/10.1016/j.cu...

The Fat-Dachsous planar polarity pathway competes with hinge contraction to orient polarized cell behaviors during Drosophila wing morphogenesis

Morphogenesis involves interactions between biochemical and mechanical cues. Trinidad et al. show that during Drosophila pupal wing morphogenesis, Fat-Dachsous planar polarity competes with tissue tension to control oriented cell behaviors. Moreover, junctional tension stabilizes Fat-Dachsous, supporting the existence of biomechanical feedback.

For my planar polarity follower(s?), we have a new paper out on Fat-Dachsous. Fat-Dachsous are known to interact (signal?) in trans between cells, but we now find a second (more important!) trans-interaction suggesting new models for Fat-Dachsous clustering www.sciencedirect.com/science/arti...
