Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD) is a chronic disease with increasing prevalence and for which non-invasive biomarkers are needed. Environmental endocrine disruptors (EDs) are known to be involved in the onset and progression of MASLD and assays to monitor their impact on the liver are being developed. Extracellular vesicles (EVs) mediate cell communication and their content reflects the pathophysiological state of the cells from which they are released.

Article Synopsis
  • Polycyclic aromatic hydrocarbons (PAHs), especially benzo(a)pyrene (B(a)P), are harmful environmental contaminants linked to serious health issues like cancer and immune system suppression.
  • This study investigates the use of extracellular vesicles (EVs) and their microRNA (miRNA) content as potential biomarkers for PAH exposure, focusing on changes in EV production and miRNA profiles following exposure to B(a)P.
  • The findings show that B(a)P exposure increases EV production and specifically regulates the expression of miR-342-3p, suggesting that EVs and miRNAs could serve as valuable indicators of PAH exposure in toxicological assessments.

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease. Up to now, no treatment can stop the progression of IPF. Vitamin D3 (VD) reduces experimental lung fibrosis in murine models and depletion of vitamin D3 might be associated with the reduced survival of patients with IPF.

The incidence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing worldwide. This disease encompasses several stages, from steatosis to steatohepatitis and, eventually, to fibrosis and cirrhosis. Exposure to environmental contaminants is one of the risk factors and an increasing amount of evidence points to a role for endocrine disrupting compounds (EDCs).

Article Synopsis
  • * Key components, like polycyclic aromatic hydrocarbons (PAHs), activate the aryl hydrocarbon receptor (AhR), leading to processes that promote tumor development, including DNA damage and oxidative stress.
  • * It appears that lung cancer associated with outdoor air pollution primarily promotes tumor growth in cells with pre-existing genetic mutations rather than causing typical mutations directly, indicating different mechanisms at play compared to smoking-related lung cancer.
