Gestational diabetes mellitus and subsequent cardiovascular disease in a period of rising diagnoses: Cohort study.

Acta Obstet Gynecol Scand

January 2025

Department of Epidemiology, Biostatistics and Occupational Health, McGill University, Montreal, Quebec, Canada.

Introduction: Evidence suggests that gestational diabetes mellitus (GDM) is associated with subsequent cardiovascular disease; however, it is unclear what impact changes in screening and diagnostic criteria have had on the association of GDM with long-term outcomes such as cardiovascular disease. The purpose of this study was to determine the association between GDM and subsequent cardiovascular disease during a period of rising gestational diabetes diagnosis in England. Specifically, associations were compared before and after 2008, when national guidelines supporting risk factor-based screening were introduced.

The USP19 deubiquitinase is found in a locus associated with Parkinson's Disease (PD), interacts with chaperonins, and promotes secretion of α-synuclein (α-syn) through the misfolding-associated protein secretion (MAPS) pathway. Since these processes might modulate the processing of α-syn aggregates in PD, we inactivated USP19 (KO) in mice expressing the A53T mutation of α-syn and in whom α-syn preformed fibrils (PFF) had been injected in the striatum. Compared to WT, KO brains showed decreased accumulation of phospho-synuclein (pSyn) positive aggregates.

Role of extracellular vesicles in cancer-specific interactions between tumour cells and the vasculature.

Semin Cancer Biol

December 2022

Cancer progression impacts and exploits the vascular system in several highly consequential ways. Among different types of vascular cells, blood cells and mediators that are engaged in these processes, endothelial cells are at the centre of the underlying circuitry, as crucial constituents of angiogenesis, angiocrine stimulation, non-angiogenic vascular growth, interactions with the coagulation system and other responses. Tumour-vascular interactions involve soluble factors, extracellular matrix molecules, cell-cell contacts, as well as extracellular vesicles (EVs) carrying assemblies of molecular effectors.

Cancer associated thrombosis (CAT) including venous and arterial thromboembolism (VTE and ATE respectively), as well as subclinical hypercoagulable states pose a risk of serious morbidity and mortality and poor outcomes in cancer patients. It is increasingly clear that rather than being unspecific aftermaths of tumour growth, CAT is causally linked to the molecular phenotype of cancer cells and its genetic and epigenetic oncogenic drivers. Emerging data suggest that mutational events and factors modifying chromatin architecture in cancer cells influence the repertoire of genes (coagulome) the products of which may interact with the hemostatic system either directly or through modification of inflammatory system or release of cancer-related prothrombotic extracellular vesicles (EVs).
