Decoupling enzyme catalysis from thermal denaturation [PDF]

open access: yes, 2010
The equilibrium model (EM) (Daniel et al., 2001) postulates two forms of a folded enzyme, one catalytically active (Eact) and the other inactive (Einact), which interconvert via a fast thermal equilibrium (Keq) (Figure A). This model for enzyme catalysis

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Training differentially regulates elastin level and proteolysis in skeletal and heart muscles and aorta in healthy rats

open access: yesBiology Open, 2016
Exercise induces changes in muscle fibers and the extracellular matrix that may depend on elastin content and the activity of proteolytic enzymes. We investigated the influence of endurance training on the gene expression and protein content and/or ...

Extracellular proteolytic enzyme activity in sediments of an intertidal mudflat [PDF]

open access: yesLimnology and Oceanography, 1989
Extracellular proteolytic activity (EPA) on an intertidal mudflat was examined over a 2‐yr period, with focus on characteristics of enzyme systems and the controlling influences on enzyme activity levels. EPA was primarily associated with the particulate rather than the pore‐water phase.

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

open access: yesMolecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer

open access: yesMolecular Oncology, EarlyView.
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

Optimization of seminal extracellular vesicle isolation protocols for cancer biomarker analysis using proteomic profiling

open access: yesMolecular Oncology, EarlyView.
This paper shows that size‐exclusion chromatography and sequential centrifugation applied to seminal plasma enrich for different populations of extracellular vesicles. This may significantly affect the detection and analysis of extracellular vesicle‐associated cancer biomarkers.

Strategy for improving extracellular lipolytic activities by a novel thermotolerant Staphylococcus sp. strain

open access: yesLipids in Health and Disease, 2011
Background Extracellular bacterial lipases received much attention for their substrate specificity and their ability to function under extreme environments (pH, temperature...).
