Abstract

The xenoestrogen bisphenol A (BPA), a commonly used industrial chemical, has been linked to endocrine disruption. The point of the study was to consider the effects of chronic BPA exposure on the respiratory system of adult female rats, and the potential mitigating benefits of Sodium hydrosulfide (NaHS), a donor of hydrogen sulfide (HS) administration. Detect biomarkers in Bronchoalveolar lavage fluid (BALF), including total protein content, Total cell counts, Neutrophils %, ICAM (intercellular adhesion molecule)-1 and TGF-β (Transforming growth factor beta). NaHS significantly reduced pro-inflammatory cytokines (IFN-β and MCAF,) also reduce (i.e. VCAM-1, VEGF, VIM, MMP-2, MMP-9), and reduced malondialdehyde and augmented activities of SOD and GSH-PX. Notably, HS induced a marked decrease in the expression levels of p-extracellular signal-regulated protein kinase (p-ERK), p-c-Jun N-terminal kinase (p-JNK), and p-p38, HS inhibits BPA-induced inflammation and injury in alveolar epithelial cells. These results suggest NaHS may prevent inflammation via the suppression of the ERK/JNK/ p-p38MAPK signaling pathway, Subsequent inhibition of inflammation, epithelial cell injury, and apoptosis may be providing insight into potential avenues for the treatment of lung injury.
