IGF-1 impacts neocortical interneuron connectivity in epileptic spasm generation and resolution

Neurotherapeutics
Little is known about the mechanisms that generate epileptic spasms following perinatal brain injury. Recent studies have implicated reduced levels of Insulin-like Growth Factor 1 (IGF-1) in these patients’ brains.

Atrophic Skeletal Muscle‐Derived Extracellular Vesicles Transfer miR‐125a‐5p to Inhibit Bone Formation in Osteoporosis during Aging

Advanced Science, EarlyView.
A muscle‐bone endocrine pathway in aging is revealed in which extracellular vesicles released from atrophic skeletal muscle (Aged‐SKM‐EVs) inhibit bone formation. These EVs deliver miR‐125a‐5p to osteoblasts, thereby suppressing the SIRT7‐Sp7 signaling axis and osteogenic differentiation.

Serum insulin-like growth factor-1 as a potential marker for MDD diagnosis, its clinical characteristics, and treatment efficacy validation: data from an open-label vortioxetine study

BMC Psychiatry, 2020
Background IGF-1 is an essential neurotrophin produced peripherally and in the brain. Impairments in the brain IGF-1 concentrations might be responsible for some aspects of major depressive disorder (MDD) pathogenesis, whereas peripheral IGF-1 could have

GALNT10 Affects O‐Glycosylation of IGFBP7 to Promote Tumor Vascular Remodeling and Metastasis of Ovarian Cancer

Advanced Science, EarlyView.
The glycosyltransferase GALNT10 facilitates ovarian cancer metastasis through the induction of tumor cell EMT and tumor vascular dysfunction. GALNT10 enhanced the extracellular secretion of IGFBP7 through O‐GalNAc glycosylation modification at the T188 site, which subsequently interacts with CD93 on endothelial cells, leading to vascular remodeling ...

Direct Selection of Functional De Novo Macrocycles for Activation of On‐Cellulo Insulin Receptor

Angewandte Chemie, EarlyView.
A live‐cell screening platform, RaPID‐ExCells, integrates mRNA display‐derived macrocyclic peptide libraries with functional selection against native cell‐surface receptors. Application to the insulin receptor enabled de novo discovery of a macrocyclic agonist that activates endogenous signaling despite weak in vitro binding, highlighting the power of ...

Mitochondrial CircRNA CircMT‐RNR2 Safeguards Antioxidant Defense to Support Fibroblast Functions in Wound Repair

Advanced Science, EarlyView.
CircMT‐RNR2 promotes wound healing by enhancing fibroblast proliferation, migration, contraction, and extracellular matrix (ECM) production. It sustains mitochondrial redox balance by stabilizing the antioxidant protein PRDX3, thereby reducing ROS‐induced damage. In diabetic foot ulcers, hypoxia, hyperglycemia, and reduced FGF2 and EGF expression lower

Avaliação plasmática de igf-1 no prolactinoma IGF-1 plasma levels evaluation in prolactinoma

Arquivos de Neuro-Psiquiatria, 2006
Prolactinomas são os tumores hipofisários mais comuns, podendo co-secretar GH (hormônio do crescimento). IGF-1 (fator de crescimento insulina-símile-1) é o principal responsável pelas ações do GH e parâmetro diagnóstico de acromegalia.

Bone Organoids: A Novel Tool for Modeling and Managing Skeletal Disorders in Diabetes

Advanced Science, EarlyView.
This review synthesizes advances in bone organoid engineering and evaluates their potential to model diabetic bone fragility. Current in vitro and animal models do not fully recapitulate diabetes‐associated skeletal phenotypes. Cell‐based and scaffold‐based bone organoids are discussed as complementary approaches to reconstruct multicellular bone ...

Potent and Selective IGF‐IIR‐Recruiting Bifunctional Molecules for Targeted Lysosomal Degradation of Extracellular and Membrane Proteins

Advanced Science, EarlyView.
Lysosome‐targeting chimeras (LYTACs) enable degradation of extracellular and membrane proteins via lysosomal trafficking. We report a novel IGF‐II mutant (Del1–7, Y27L) that selectively engages IGF‐IIR while avoiding IGF‐IR and IR‐A. mutIGF‐II–based LYTACs enhance target internalization and degradation and support a genetically encodable, all‐protein ...
