Molecular crosstalk via exosomes in lung cancer progression

Interdisciplinary Medicine, EarlyView.
“Molecular and theranostics roles of exosomes in Lung Cancer.” Abstract Exosomes play a critical role in lung cancer metastasis, facilitating tumor progression through intercellular communication between cancer cells and the tumor microenvironment. These nanosized extracellular vesicles carry bioactive molecules such as proteins, nucleic acids, and ...

In Vitro Membrane Remodeling by ESCRT is Regulated by Negative Feedback from Membrane Tension

iScience, 2019
Summary: Artificial cells can shed new light on the molecular basis for life and hold potential for new chemical technologies. Inspired by how nature dynamically regulates its membrane compartments, we aim to repurpose the endosomal sorting complex ...

Oncogenic H‐Ras Reprograms Madin‐Darby Canine Kidney (MDCK) Cell‐Derived Midbody Remnant Proteome Following Epithelial‐Mesenchymal Transition

PROTEOMICS, EarlyView.
ABSTRACT Epithelial‐mesenchymal transition (EMT) is a fundamental, dynamic cellular process involved in embryonic development, metastasis, organ fibrosis, and tissue regeneration. To define the molecular landscape of secreted midbody remnants (MBRs) to the EMT process, a proteome analysis of MBRs released from Madin–Darby canine kidney (MDCK) cells and

The role of VPS4 in ESCRT-III polymer remodeling [PDF]

Biochemical Society Transactions, 2019
Abstract The endosomal sorting complex required for transport-III (ESCRT-III) and VPS4 catalyze a variety of membrane-remodeling processes in eukaryotes and archaea. Common to these processes is the dynamic recruitment of ESCRT-III proteins from the cytosol to the inner face of a membrane neck structure, their activation and filament ...

The auxiliary ESCRT complexes provide robustness to cold in poikilothermic organisms

Biology Open, 2019
The ESCRT pathway, comprising the in sequence acting ESCRT-0, -I, -II, -III and Vps4 complexes, conducts the abscission of membranes away from the cytosol.

Migrasomes, Matrix‐Bound Nanovesicles, and More: Messengers in the Matrix

PROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) and particles (EPs) are diverse micro‐ and nanoparticles that circulate in bodily fluids and can attach to, or be deposited onto, the extracellular matrix (ECM) and other surfaces. To date, the nomenclature and classification of matrix‐bound or matrix‐associated EVs and EPs (MEVPs) have been unclear, largely due to

Assembly of the AAA ATPase Vps4 on ESCRT-III [PDF]

Molecular Biology of the Cell, 2010
Vps4 is a key enzyme that functions in endosomal protein trafficking, cytokinesis, and retroviral budding. Vps4 activity is regulated by its recruitment from the cytoplasm to ESCRT-III, where the protein oligomerizes into an active ATPase. The recruitment and oligomerization steps are mediated by a complex network of at least 12 distinct interactions ...

Proteomic and Lipidomic Profiling of Immune Cell‐Derived Subpopulations of Extracellular Vesicles

PROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are heterogeneous and play important roles in intercellular communication, contributing to physiological and pathological processes. Since few markers currently exist to differentiate subtypes of EVs, this study aimed to determine proteomic and lipidomic differences among four EV subpopulations. Large and small EVs

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Harnessing the Therapeutic Potential of Cell Secretomes and Extracellular Vesicles for Craniofacial Regenerative Applications

Journal of Periodontal Research, EarlyView.
The scoping review summarizes the current preclinical and clinical evidence for the use of “cell‐free” therapies in craniofacial (periodontal, bone and soft‐tissue) regeneration. It also aims to highlight key challenges and strategies towards the clinical translation of these therapies.
