Diet-derived Microbial Metabolites Modulate Stress-Responsive Gene Expression in Germ-free Zebrafish

Using a robogut bioreactor system, this study demonstrates that while diverse diets and fiber supplements yield distinct short-chain fatty acid profiles with minimal impact on microbial composition, the resulting diet-derived metabolites specifically mitigate stress-induced *bdnf* expression in germ-free zebrafish, highlighting the critical role of donor-specific microbial metabolite output in modulating host neurodevelopmental and immune responses.

A JNK-interacting protein 1 acts across the midline to mediate synaptic localization of the SARM1 calcium-signaling scaffold protein for asymmetric neuronal fate choice

This study reveals that the conserved JNK-interacting protein JIP-1 acts non-cell autonomously in the AWCON neuron to mediate the synaptic localization of the TIR-1/SARM1 calcium-signaling scaffold, thereby driving the asymmetric fate specification of the AWC olfactory neuron pair in *C. elegans*.

Wunen(s) help navigate Primordial Germ Cells by attenuating Hedgehog signaling

This study demonstrates that Wunen and Wunen2 guide Drosophila primordial germ cell migration by attenuating Hedgehog signaling through both non-autonomous and autonomous mechanisms, specifically by inhibiting Smoothened membrane localization and preventing the precocious clumping of germ cells.

Plac1 Ablation Disrupts Signaling Pathways Essential for Prenatal Development and Induces a Preeclampsia-Associated Transcriptomic Signature

This study demonstrates that ablation of the X-linked gene Plac1 disrupts essential signaling pathways governing placental development and induces a preeclampsia-associated transcriptomic signature, leading to fetal growth restriction and increased embryopathy risk consistent with the Developmental Origins of Health and Disease framework.

H2A.Z levels control the timing of major events at the maternal-zygotic transition

This study demonstrates that the dosage of the histone variant H2Av/H2A.Z acts as a conserved timer controlling the timing of key maternal-zygotic transition events, such as cell cycle progression and transcript turnover, while also revealing that its nuclear abundance specifically regulates cell cycle timing but not the full scope of transcriptome remodeling.

Concomitant DNA hydroxymethylation and histone H2B O-GlcNAcylation are prerequisites for zygotic genome activation in mice

This study reveals that successful zygotic genome activation in mice requires the coordinated action of Tet3-mediated DNA hydroxymethylation and OGT-mediated histone H2B O-GlcNAcylation on the paternal chromatin, where Stella selectively restricts OGT to the paternal genome to establish a dual epigenetic signature essential for transcriptional reprogramming.

Cohesin and NuRD Antagonistically Drive Alternative Neuronal Fates via PLZF Transcription Factors

This study reveals that in *C. elegans*, cohesin and the PLZF homolog EOR-1 promote GABAergic neuronal fate, while the NuRD complex and another PLZF homolog (TRA-4) drive an alternative tyraminergic fate when cohesin function is lost, demonstrating an antagonistic mechanism where genome architecture, epigenetic remodeling, and transcriptional regulation cooperate to specify neuronal identity.

Temporal degradation of PRC2 uncovers specific developmental dependencies

By combining rapid protein degradation with a scalable embryoid model, this study reveals that temporal loss of PRC2 causes specific developmental failures driven by ectopic expression of anterior and lateral lineage genes, where gene sensitivity is determined by the presence of cognate transcription factors and the timing of depletion relative to the exit from pluripotency.

Interactions between the myosin Dachs, the adaptor Dlish, and the palmitoyltransferase Approximated mediate Fat-Dachsous signaling

This study elucidates how the adaptor Dlish, palmitoylated by Approximated, mediates the Fat-Dachsous signaling pathway by tethering Dachs to the cortex and coupling it to opposing stabilization and destabilization effects from Ds and Fat, respectively, while protecting Dlish from degradation.
