MARCH1 regulates insulin sensitivity by controlling cell surface insulin receptor levels

Nature Communications, 2016
Insulin receptor levels at the cell surface are reduced in insulin resistance, for reasons that are not fully understood. Here, the authors identify the E3 ubiquitin ligase MARCH1 as a direct regulator of basal insulin receptor surface levels and ...

Low-Density Lipoprotein Receptor-Related Protein-1 Protects Against Hepatic Insulin Resistance and Hepatic Steatosis

EBioMedicine, 2016
Low-density lipoprotein receptor-related protein-1 (LRP1) is a multifunctional uptake receptor for chylomicron remnants in the liver. In vascular smooth muscle cells LRP1 controls reverse cholesterol transport through platelet-derived growth factor ...

The insulin superfamily of growth-promoting proteins [PDF]

arXiv, 2007
Recently, structural analysis of the human transferrin and growth hormone (GH) amino acid sequences has unravelled that they harbor a motif identical to a pattern found in viral oncoproteins known to bind the primarily nuclear tumor suppressor retinoblastoma protein (RB).

Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects

Advanced Functional Materials, EarlyView.
Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...

Modeling the distribution of insulin in pancreas [PDF]

arXiv
Maintenance of adequate physical and functional pancreatic $\beta$-cell mass is critical for the prevention or delay of diabetes mellitus. It is well established that insulin potently activates mitogenic and anti-apoptotic signaling cascades in cultured $\beta$-cells.

Inhibition of central insulin-receptor signaling by S961 causes hyperglycemia and glucose intolerance in rats [PDF]

, 2011
Genetic ablation studies confirmed the role of central insulin-receptor signaling (CIRS) in fuel metabolism. However, the need to examine the role of CIRS in glucose homeostasis under normal physiological condition is indispensable, as insulin affects ...

Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

Advanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Integration of TGF-β-induced Smad signaling in the insulin-induced transcriptional response in endothelial cells. [PDF]

, 2019
Insulin signaling governs many processes including glucose homeostasis and metabolism, and is therapeutically used to treat hyperglycemia in diabetes. We demonstrated that insulin-induced Akt activation enhances the sensitivity to TGF-β by directing an ...

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy

Advanced Functional Materials, EarlyView.
MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation

Antiproliferative MCR peptides block physical interaction of insulin with retinoblastoma protein (RB) in human lung cancer cells [PDF]

arXiv, 2007
Fifteen years ago, a structural analysis of the hormone insulin and the retinoblastoma tumor suppressor protein (RB) revealed that they may physically interact with one another. Subsequently, an RB peptide corresponding to the proposed RB binding site for insulin was found to recognize full-length insulin in vitro.
