RUNX2 Activation in Fibro/Adipogenic Progenitors Promotes Muscle Fibrosis in Muscular Dystrophy

open access: yesAdvanced Science, EarlyView.
This study revealed a novel role of the chemokine‐TGF‐β1‐RUNX2 axis in determining the fate of FAP differentiation and modulating muscle fibrosis in patients and mice with muscular dystrophies. ABSTRACT Clinical evidence indicates concurrent muscle inflammation and fibrosis in muscular dystrophies (MDs); however, the molecular mechanisms underlying ...

Conditional ergodicity in infinite dimension

open access: yes, 2014
The goal of this paper is to develop a general method to establish conditional ergodicity of infinite-dimensional Markov chains. Given a Markov chain in a product space, we aim to understand the ergodic properties of its conditional distributions given ...

LMO7 Suppresses Tumor‐Associated Macrophage Phagocytosis of Tumor Cells Through Degradation of LRP1

open access: yesAdvanced Science, EarlyView.
LMO7 in tumor‐associated macrophages suppresses phagocytosis of tumor cells and limits cytotoxic T lymphocytes infiltration, fostering tumor progression. Mechanistically, LMO7 mediates the ubiquitination and degradation of the phagocytic receptor LRP1, impairing its ability to engulf tumor cells and driving macrophages toward an antitumor phenotype ...

Lipid‐Driven OLR1/FOXM1/FGF19 Axis Orchestrates Crosstalk in an Epithelial‐Fibroblast Positive Feedback Promoting Progesterone Resistance in Endometrial Cancer

open access: yesAdvanced Science, EarlyView.
It is revealed that a metabolic–stromal loop driven by oxLDL–OLR1–FOXM1–FGF19 signaling promotes progesterone resistance in endometrial cancer. OxLDL activates epithelial–fibroblast crosstalk, enhancing proliferation and hormonal insensitivity. Disruption of this circuit, especially with resveratrol, restores MPA sensitivity, highlighting a potential ...

Adenylyl Cyclase 8 in Dorsal CA1 Neurons Prevents Depressive‐Like Behaviors by Maintaining Neuronal Excitability and Glutamatergic Neurotransmission Through TIP39‐PTH2R Signaling

open access: yesAdvanced Science, EarlyView.
Depression, a prevalent neuropsychiatric disorder with unclear pathogenesis, involves dysfunctional adenylyl cyclase 8 (Adcy8) as a key risk factor. Chronic stress selectively reduces Adcy8 expression in the dorsal CA1 (dCA1) neurons. Depletion of Adcy8 in dCA1 excitatory neurons induces depressive‐like behaviors by impairing neuronal excitability and ...

The Non-Regular CEO Problem

open access: yes, 2015
We consider the CEO problem for non-regular source distributions (such as uniform or truncated Gaussian). A group of agents observe independently corrupted versions of data and transmit coded versions over rate-limited links to a CEO.

MGM as a Large‐Scale Pretrained Foundation Model for Microbiome Analyses in Diverse Contexts

open access: yesAdvanced Science, EarlyView.
We present the Microbial General Model (MGM), a transformer‐based foundation model pretrained on over 260,000 microbiome samples. MGM learns contextualized microbial representations via self‐supervised language modeling, enabling robust transfer learning, cross‐regional generalization, keystone taxa discovery, and prompt‐guided generation of realistic,
