Would be helpful to have a scale bar. The cilia look 10x longer than the size of the nuclei… and the width/diameter should be <300 nm…

Lots of potential for future ciliary (and non-ciliary) screening applications. Great work by all authors, especially postdoc Jingbo Sun. And great collaboration with the Khokha lab!

David Breslow Lab @davidbreslowlab.bsky.social · 20/11/2025
We find that SMIM27/TZMP1 KO cells fail to form cilia. TZMP1 localizes to the transition and by IP/MS is part of the MKS complex at the transition zone. With Mustafa Khokha, we find conserved roles in ciliary function in Xenopus embryos.

David Breslow Lab @davidbreslowlab.bsky.social · 20/11/2025
Among hits, we characterize SMIM27/TZMP1 as a new microprotein component of the ciliary transition zone. A crazy gene... prev thought to be a lncRNA, it encodes a 55aa protein and overlaps another gene such that its start codon overlaps the start codon of a gene expressed from opposite strand!

David Breslow Lab @davidbreslowlab.bsky.social · 20/11/2025
We applied this technology in a series of genome-wide and targeted screens... We find known and novel ciliary regulators and we combine results from complementary screens to get multi-parameter phenotypic profiles with rich functional information.

David Breslow Lab @davidbreslowlab.bsky.social · 20/11/2025
Two methodologic highlights: 1) photoactivation in fixed cells using a PA small molecule dye, enabling use of Ab staining to define phenotypes (flexible analysis of diverse markers, including PTMs), 2) use of commercial microscope hardware and software (don't need to be an optics/programming expert)

David Breslow Lab @davidbreslowlab.bsky.social · 20/11/2025
Here we build on prior strategies that convert microscopy phenotypes into FACS-sortable fluorescence differences. The workflow combines: automated high-throughput imaging; AI-based ID of cells with desired phenotype; targeted photoactivation of these cells; cell recovery by FACS for sgRNA sequencing

As FCD is often caused by somatic GOF mutations, we wondered if aberrant cilia disassembly may occur in FCD. We found that FCD-linked mutations in SARM1 or RhoA act like GOF variants and potentiate cilia loss. Cilia loss via SARM1 also occurs for mTORC1-activating alterations commonly seen in FCD...

It seems there are many type 4 R01s issuing mult years of funding at once, possibly in lieu of standard non-competing renewals (i.e. MYF). I see ~220 awards, >450 grant-years, >$175m direct costs. I'm not familiar with type 4, but looks like ~10X as many since May than all of last year.
