Abstract

Parishin, a natural compound, has demonstrated significant potential in mitigating age-related phenotypes and improving outcomes in age-associated diseases. Given that aging is a major risk factor for numerous chronic conditions, including pulmonary fibrosis, we investigated parishin's effects on cellular senescence and lung health. In our study, we treated mouse lung epithelial cells with parishin and observed a reduction in cellular senescence markers alongside an upregulation of sirtuin 1 (SIRT1). Building on these in vitro findings, we administered parishin to naturally aged mice. The treatment resulted in decreased pulmonary fibrosis and reduced DNA damage in lung tissue. Notably, we found that parishin treatment led to a reduction in Cluster of differentiation 38 (CD38) levels, concomitant with an increase in SIRT1 expression. These findings indicate that parishin may enhance lung function in aged mice, suggesting its potential as a therapeutic agent for treating age-related pulmonary disorders.
