RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells
FEBS Open Bio, EarlyView.RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells
FEBS Open Bio, EarlyView.Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Rôle de la GTPase RhoB dans l'oncogenèse pulmonaire [PDF]
, 2010 Le cancer bronchique est la première cause de mortalité par cancer dans le monde et ceci est largement dû à des diagnostics tardifs et à un fort pouvoir métastatique.
Bousquet, Emilie

Insulin stimulates a novel GTPase activity in human platelets [PDF]
, 1987 Insulin stimulated the activity of a high-affinity GTPase activity in human platelet membranes some 62% over that of the basal activity. Half-maximal stimulation (Ka) was achieved with 3.1 nM insulin. The Km for GTP of the insulin-stimulated GTPase was 0.

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Rho GTPase expression in macrophages and osteoclasts.
, 2012 (A) Rho GTPase expression in macrophages generated with M-CSF or GM-CSF. The percentage of total Rho GTPase expression is depicted for each macrophage type in a pie chart. Rho GTPase subfamilies and individual Rho GTPases are color coded.

Protocol for quantifying miRNA trafficking across the endosomal membrane
FEBS Open Bio, EarlyView.An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Uncovering G Protein‐Coupled Receptors: Novel Targets and Biomarkers for Predicting Glioma Prognosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Low‐grade gliomas (LGG) exhibit significant heterogeneity and recurrence risk. G protein‐coupled receptors (GPCR) contribute to glioma malignant progression, but their prognostic value remains unclear. This work attempts to formulate a GPCR‐based outcome‐predicting model for LGG. Methods Based on TCGA LGG data, the enrichment scores
