Sustained IGF-1 Secretion by Adipose-Derived Stem Cells Improves Infarcted Heart Function
Cell Transplantation, 2016 The mechanism by which stem cell-based therapy improves heart function is still unknown, but paracrine mechanisms seem to be involved. Adipose-derived stem cells (ADSCs) secrete several factors, including insulin-like growth factor-1 (IGF-1), which may ...

Cellular Identity Crisis: RD3 Loss Fuels Plasticity and Immune Silence in Progressive Neuroblastoma
Advanced Science, EarlyView.Researchers discovered that therapy‐induced loss of RD3 protein in neuroblastoma triggers a dangerous shift: cancer cells become more stem‐like, invasive, and resistant to treatment while evading immune detection. RD3 loss suppresses antigen presentation and boosts immune checkpoints, creating an immune‐silent environment.

IRS-1 acts as an endocytic regulator of IGF-I receptor to facilitate sustained IGF signaling
eLife, 2018 Insulin-like growth factor-I receptor (IGF-IR) preferentially regulates the long-term IGF activities including growth and metabolism. Kinetics of ligand-dependent IGF-IR endocytosis determines how IGF induces such downstream signaling outputs.

Mineralized Cryogel/Hydrogel Constructs to Recapitulate Early Breast Cancer Bone Metastasis In Vitro
Advanced Science, EarlyView.A new biphasic in vitro cryogel/hydrogel model of early breast cancer bone metastasis provides precise control over microenvironmental cues and microscopic access to the spatiotemporal cancer cell distribution. Deposited bone‐like mineral is observed to strongly impede the effects of biomolecular signals, as evidenced by both colonization profiles and ...

Advanced Science, EarlyView.Impaired endometrial receptivity contributes to the poor pregnancy outcomes in women with PCOS. The authors found that decreased endometrial IL‐22 levels and disrupted STAT3‐IGFBP5 signaling pathway contributed to impaired endometrial receptivity. Supplementation with IL‐22 or IGFBP5 exerts a protective effect on implantation failure in PCOS‐like mice,

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities
Advanced Science, EarlyView.T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Brain Science Advances, 2017 Insulin-like growth factor 1 (IGF-1) is a pluripotent growth factor, with multiple functions in the peripheral and central nervous systems. Increasing evidence suggests that IGF-1 fine-tunes the development of the central nervous system, ensuring proper ...

Stem Cells International, 2020 Background and Purpose. Previously, we found that insulin-like growth factor-1 (IGF-1) levels in the infarct cortex in the acute phase of distal middle cerebral artery occlusion (dMCAO) rats are increased by intravenous infusion of allogeneic mesenchymal

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

Advanced Science, EarlyView.Bimodal modulation of nitric oxide in endothelial cells is achieved by light‐sensitive polymer nanoparticles. In dark, P3HT/PEDOT:PSS NPs boost intracellular ·NO, upregulate both endothelial and induced nitric oxide synthase, and drive a metabolic shift toward glycolysis.
