Breast Cancer‐Secreted DPP3 Promotes Lung Metastasis by Remodelling the Vascular Niche in Lung via the Rap1 Signalling Pathway

Journal of Extracellular Vesicles, Volume 14, Issue 12, December 2025.
ABSTRACT Metastasis is the leading cause of death related to breast cancer. Premetastatic niches (PMNs), which are remodelled by the primary tumours in distant organs, are essential for the colonisation of disseminated cancer cells. The vascular niche is among the most pivotal PMNs in breast cancer lung metastasis, and the underlying mechanism remains ...

Pathophysiology of acute experimental pancreatitis: Lessons from genetically engineered animal models and new molecular approaches [PDF]

, 2005
The incidence of acute pancreatitis is growing and worldwide population-based studies report a doubling or tripling since the 1970s. 25% of acute pancreatitis are severe and associated with histological changes of necrotizing pancreatitis. There is still

Development and Validation of a High‐Throughput Screening Assay for the Legionella ADP‐Ribosyl Transferase SdeA

ChemBioChem, Volume 26, Issue 21, November 8, 2025.
We show the optimization and application of a fluorogenic assay to monitor Legionella SdeA activity in a High‐Throughput‐Screening campaign. Ubiquitination of proteins is one of the most crucial post‐translational modifications in eukaryotic cells, typically involving conjugation of ubiquitin to a lysine residue in a substrate using a three‐enzyme ...

Parkinson disease-associated mutations in LRRK2 cause centrosomal defects via Rab8a phosphorylation

Molecular Neurodegeneration, 2018
Background Mutations in LRRK2 are a common genetic cause of Parkinson’s disease (PD). LRRK2 interacts with and phosphorylates a subset of Rab proteins including Rab8a, a protein which has been implicated in various centrosome-related events. However, the

Signal transduction gRABs attention [PDF]

, 2006
Rab proteins are small GTPases involved in the regulation of vesicular membrane traffic. Research done in the past years has demonstrated that some of these proteins are under the control of signal transduction pathways.

Breaking barriers: The cGAS‐STING pathway as a novel frontier in cancer immunotherapy

Cancer Communications, Volume 45, Issue 11, Page 1513-1546, November 2025.
Abstract Since its discovery, the cyclic GMP‐AMP synthase (cGAS)‐stimulator of the interferon gene (STING) signaling pathway has been considered a pivotal component of innate immunity and a promising target for cancer immunotherapy. Beyond its canonical role in pathogen defense, accumulating evidence has demonstrated that the cGAS‐STING pathway ...

Role of Seminal Exosomes in Reproduction

Journal of Cellular Physiology, Volume 240, Issue 11, November 2025.
ABSTRACT Exosomes are small lipid bilayer vesicles, ranging from 30 to 150 nm in diameter, that are secreted by various cells and facilitate intercellular communication. They originate from the endosomal system and release their contents into the extracellular environment.

Membrane trafficking alterations in breast cancer progression

Frontiers in Cell and Developmental Biology
Breast cancer (BC) is the most common type of cancer in women, and remains one of the major causes of death in women worldwide. It is now well established that alterations in membrane trafficking are implicated in BC progression.
