The Role and Therapeutic Potential of Macropinocytosis in Cancer

open access: yesFrontiers in Pharmacology, 2022
Macropinocytosis, a unique endocytosis pathway characterized by nonspecific internalization, has a vital role in the uptake of extracellular substances and antigen presentation.

SNAT7 regulates mTORC1 via macropinocytosis

open access: yesProceedings of the National Academy of Sciences, 2022
Significance The mammalian target of rapamycin complex 1 (mTORC1) signaling pathway is frequently elevated in human disease, including cancer, type 2 diabetes, metabolic disorders, and neurodegeneration. We identify SNAT7 as an important regulator of mTORC1.

Macropinocytosis in Phagocytes: Regulation of MHC Class-II-Restricted Antigen Presentation in Dendritic Cells

open access: yesFrontiers in Physiology, 2015
Dendritic cells (DCs) are outstanding antigen presenting cells (APCs) due to their robust ability to internalize extracellular antigens using endocytic processes such as receptor-mediated endocytosis, phagocytosis, and macropinocytosis.

The PMA phorbol ester tumor promoter increases canonical Wnt signaling via macropinocytosis

open access: yeseLife, 2023
Activation of the Wnt pathway lies at the core of many human cancers. Wnt and macropinocytosis are often active in the same processes, and understanding how Wnt signaling and membrane trafficking cooperate should improve our understanding of embryonic ...

Wnt, GSK3, and Macropinocytosis

open access: yes, 2022
Here we review the regulation of macropinocytosis by Wnt growth factor signaling. Canonical Wnt signaling is normally thought of as a regulator of nuclear β-catenin, but emerging results indicate that there is much more than β-catenin to the Wnt pathway. Macropinocytosis is transiently regulated by EGF-RTK-Ras-PI3K signaling.

Exploration of Deformation of F-Actin during Macropinocytosis by Confocal Microscopy and 3D-Structured Illumination Microscopy

open access: yesPhotonics, 2022
Since their invention, confocal microscopy and super-resolution microscopy have become important choices in cell biology research. Macropinocytosis is a critical form of endocytosis.

Uses and abuses of macropinocytosis [PDF]

open access: yesJournal of Cell Science, 2016
ABSTRACT Macropinocytosis is a means by which eukaryotic cells ingest extracellular liquid and dissolved molecules. It is widely conserved amongst cells that can take on amoeboid form and, therefore, appears to be an ancient feature that can be traced back to an early stage of evolution.

Macropinocytosis: New Insights Into Its Underappreciated Role in Innate Immune Cell Surveillance

open access: yesFrontiers in Immunology, 2018
Macropinocytosis has received increasing attention in recent years for its various roles in nutrient acquisition, immune surveillance, and virus and cancer pathologies.

Macropinocytosis, mTORC1 and cellular growth control [PDF]

open access: yesCellular 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 ...

Macropinocytosis confers resistance to therapies targeting cancer anabolism

open access: yesNature Communications, 2020
Macropinocytosis allows cancer cells to cope with nutrient stress. Here, the authors use a selective, genetic approach to inhibit macropinocytosis and show that consuming necrotic cell debris via macropinocytosis—necrocytosis—affords resistance to many ...
