Back to the office after a great time at the GFÖ conference! We shared talks & posters on bee health, ground-nesting, grassland #Restoration, bird #Conservation, combinations of landscape-scale conservation measures, and the establishment of perennial flower fields as #AECM.

Plots showing how many collagens, ZP domain proteins, or other ECM families are expressed in a pulsatile manner in each cell type.
Using these new tools, we could ask what kinds of genes oscillate in glia, or skin, or pharynx. For glia and skin it turns out it's mostly #aECM - lots of collagens, ZP domain proteins, and other cuticle proteins. Pharynx has a different kind of cuticle and its oscillatory genes reflect that.

PCA plot of C. elegans ILso glia, with each cell colored by the established timing of the genes it expresses. Cells of similar color are adjacent to each other in PCA space, showing that the main source of transcriptional variation in these cells is explained by their timing within each larval stage.
We had shown that glia make the cuticle #aECM around neuronal cilia. So, we wondered if loops were a transcriptional cycle tied to cuticle synthesis.
We used expression data from @labgrosshans.bsky.social to color-code each cell based on when in the larval stage its genes are expressed. Bingo!

In this study, we uncover the critical role of #sulfation —a key post-translational modification of proteins and proteoglycan side chains—in organizing the apical extracellular matrix (aECM) during tubulogenesis. While the #aECM is essential for tissue development, it is still poorly understood.

There is so much cool #aECM work going on but most of the researchers don’t know or talk to each other; this is an attempt to change that! Link below

Catching up on more #aECM at #worm25 by watching the online videos: Physiology1 Talk23 from Jonathan Hodgkin provided evidence that, via social interactions, worms can transfer surface glycans (« BIM ») between each other to affect pathogen sensitivity. So cool!

#aECM at #worm25 : At the aECM workshop, Pooranachithra Murugesan described the ~100 protein fusions made by the Ward and Chisholm labs, identifying collagens present in different cuticle layers, tissues, and substructures - a great resource for the worm community!
