Cis‐ and Trans‐Regulatory Factors Independently Shape Phenotypic Heterogeneity of Retinitis Pigmentosa

open access: yesAdvanced Science, EarlyView.
A zebrafish model carrying an identical human RHO S334X allele reveals two independent genetic layers shaping retinitis pigmentosa (RP) severity: a protective 3‐bp cis‐regulatory insertion that attenuates transgene expression, and a dominant trans‐acting modifier that restores a severe phenotype.

Cancer‐Associated Fibroblasts Promote Tumor Immunosuppression in Hepatocellular Carcinoma via the NNMT‐ANGPTL4 Axis

open access: yesAdvanced Science, EarlyView.
ABSTRACT Background & Aims: Cancer‐associated fibroblasts (CAFs) drive immunosuppression in hepatocellular carcinoma (HCC). However, their metabolic regulation remains poorly defined. We investigated the role of nicotinamide N‐methyltransferase (NNMT) in CAFs. Approach & Results: High NNMT expression in CAF tissues was confirmed by western blotting and

Dose‐Dependent Reprogramming of Chromatin Accessibility by SOX4 Drives the Transcriptional Response to Iron Overload

open access: yesAdvanced Science, EarlyView.
This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

A Circuit of Mechanically Regulated Transcription Factors Balances Regenerative and Fibrotic Memory of Mesenchymal Stromal Cells

open access: yesAdvanced Science, EarlyView.
Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.

Development‐based In Vivo Bioreactor Strategy for Challenging Senescent Bone Reconstruction

open access: yesAdvanced Science, EarlyView.
We present a development‐based in vivo bioreactor strategy to generate rejuvenated bone grafts (vBR‐Bone) within aged hosts. By enclosing vBR‐Bone fragments within an asymmetric biomimetic periosteum, segmental femoral defects in aged mice were successfully repaired within 6 weeks. Mechanistically, the multifactors of vBR‐Bone reconstitute a remodeling
