Les Jeux olympiques de Berlin vus par la photographie de presse

Belphégor, 2017
Pendant les Jeux olympiques de Berlin, les photoreporters étrangers ont été encadrés par les autorités nazies et ont fourni, de ce fait, une masse d’images relativement homogène aux différents titres de la presse française.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Myrtle Cook, une femme à part

Belphégor, 2017
La couverture des Jeux olympiques de Berlin n’a pas fait exception à la règle en matière d’actualité sportive, alors qu’on ne dénombre qu’une seule femme attitrée au suivi des JO. En effet, Myrtle Cook, chroniqueuse sportive au Montreal Daily Star, signe

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Malaise à Olympie : Les Jeux de Berlin dans la presse française en 1936

Belphégor, 2017
Cet article traite de la couverture des Jeux olympiques de 1936 par la presse française. Il s’intéresse d’abord, dans une démarche de poétique des textes, à la pluralité des formes et des modes d’écriture journalistique auxquels les journalistes ont fait

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Le racisme à la péruvienne : contradictions et ambigüité de la notion de cholo

L'Ordinaire des Amériques, 2008
L’Indien qui migre vers la ville et devient urbain est appelé cholo ; il acquiert une identité métisse, mouvante, antagonique. Le racisme au Pérou s’exerce depuis longtemps contre les populations indigènes, mais la façon dont il se répand parmi les ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

FEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
