Celecoxib inhibits proliferation and survival of chronic myelogeous leukemia (CML) cells via AMPK-dependent regulation of β-catenin and mTORC1/2. [PDF]

, 2016
CML is effectively treated with tyrosine kinase inhibitors (TKIs). However, the efficacy of these drugs is confined to the chronic phase of the disease and development of resistance to TKIs remains a pressing issue.

Inhibition of SLC11A1‐Mediated Lysosomal Iron Accumulation in Microglia Promotes Repair Following White Matter Stroke

Advanced Science, EarlyView.
Genetic and pharmacological inhibition of SLC11A1 functioning as an H+/Fe2+ antiporter–mediated lysosomal iron accumulation in microglia promotes lysosomal lumen acidification, increases CTSD expression, enhances lysosomal myelin debris uptake and degradation, and promotes repair following white matter stroke. ABSTRACT White matter stroke (WMS) results

Depletion of Flot1 attenuates macropinosome-dependent mTORC1 activation in podocytes

Cell Structure and Function
Podocytes are terminally differentiated renal epithelial cells that play a crucial role in kidney filtration. Given this essential function, podocyte dysfunction results in kidney diseases known as podocytopathies. Previous studies have demonstrated that

mTORC1 Signaling Is Palmitoylation-Dependent in Hippocampal Neurons and Non-neuronal Cells and Involves Dynamic Palmitoylation of LAMTOR1 and mTOR

Frontiers in Cellular Neuroscience, 2019
The mechanistic target of rapamycin (mTOR) Complex 1 (mTORC1) controls growth and proliferation of non-neuronal cells, while during neuronal development mTORC1 responds to glutamate and neurotrophins to promote neuronal migration and dendritic ...

p53 suppresses type II endometrial carcinomas in mice and governs endometrial tumour aggressiveness in humans [PDF]

, 2012
Type II endometrial carcinomas are a highly aggressive group of tumour subtypes that are frequently associated with inactivation of the TP53 tumour suppressor gene.

Farnesyltransferase Deficiency in Cardiomyocytes Initiates Senescence and Contributes to Cardiac Fibrosis

Advanced Science, EarlyView.
Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...

Modulating Integrin and Growth Factor Signaling With Peptides: Strategies to Synergistically Enhance Bone Tissue Regeneration

Advanced Science, EarlyView.
It has been demonstrated that, in the bone extracellular matrix (ECM), integrins and growth factor receptors (GFRs) engage in synergistic signaling to guide bone healing and regeneration. This review provides a comprehensive overview of current strategies using ECM‐derived peptides to recreate the cellular microenvironment and harness synergistic ...

Macropinocytosis, mTORC1 and cellular growth control [PDF]

Cellular and Molecular Life Sciences, 2017
The growth and proliferation of metazoan cells are driven by cellular nutrient status and by extracellular growth factors. Growth factor receptors on cell surfaces initiate biochemical signals that increase anabolic metabolism and macropinocytosis, an actin-dependent endocytic process in which relatively large volumes of extracellular solutes and ...
