Reconstructing signaling histories of single cells via perturbation screens and transfer learning

This paper introduces IRIS, an integrated experimental-computational framework that leverages high-throughput in vitro perturbation screens and transfer learning to accurately reconstruct in vivo single-cell signaling histories, revealing combinatorial signaling codes and accelerating stem cell differentiation optimization.

Inverted Assembly of the Lens Within Ocular Organoids Reveals Alternate Paths to Ocular Morphogenesis

This study demonstrates that medaka ocular organoids can achieve a functional lens-retina structure through an alternative "inside-out" morphogenesis pathway driven by BMP and FGF signaling, revealing that self-organization in unconstrained environments can bypass the embryonic "outside-in" constraints while still producing similar structural outcomes.

Brain morphological pattern is associated with the presence, severity, and transition of transdiagnostic psychiatric disorders in preadolescents

This longitudinal study of nearly 12,000 preadolescents identifies a robust latent brain morphological pattern—characterized by larger cortical surface area and volume—that serves as a transdiagnostic vulnerability-resilience continuum, where lower scores predict the presence, severity, and persistence of psychiatric disorders while higher scores correlate with cognitive strength and mental health stability.

Intellectual disability risk gene RFX4 regulates cortical neurogenesis by restraining neuronal differentiation

This study elucidates the role of the intellectual disability risk gene RFX4 in human cortical development, demonstrating that it restrains neurogenesis by cooperating with NOTCH signaling to repress neuronal differentiation and synaptic gene expression, while also revealing distinct pathogenic mechanisms for deficiency versus specific DNA-binding domain mutations.

TGF-β signaling regulates epithelial permeability in Drosophila ovaries by modulating adhesion independent of actomyosin contractility

This study demonstrates that in Drosophila ovaries, a TGF-β signaling gradient regulates epithelial permeability by cell-autonomously suppressing tricellular junction patency through the reinforcement of E-Cadherin-based adhesion, a mechanism that operates independently of actomyosin contractility.
