Supracellular migration – beyond collective cell migration [PDF]

Journal of Cell Science, 2019
ABSTRACT Collective cell migration is a highly complex process in which groups of cells move together. A fundamental question is how cell ensembles can migrate efficiently. In some cases, the group is no more than a collection of individual cells.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Migration and Return Migration: A New Look at the Eastern Kentucky Migration Stream [PDF]

Journal of Agricultural and Applied Economics, 1974
Most studies of the economics of migration have implicitly assumed that migratory streams are homogeneous. However, migratory streams from one region to another consist of two distinct streams: a stream of first-time migrants and a stream of return migrants moving back to their area of origin. In fact, a substantial proportion of all U.S.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Chercheures… en migrations ? [PDF]

, 2014
La recherche sur les migrations ne peut faire l’économie d’une réflexion sur les conditions de son exercice. Cette exigence conduit le chercheur à interroger sa position politique et scientifique au sein du groupe social dans lequel il mène son étude.

Bordering Migration/Migrating Borders

, 2019
From the Great Wall of China to the Berlin Wall, border walls have long served as symbols of visible, fortified manifestations of sovereign control. Increasingly, however, prosperous countries utilize sophisticated legal tools to restrict mobility by detaching the border and its migration control functions from a fixed territorial marker, creating a ...
