Purpose: Increasing levels of domestic fine dust (DFD) have emerged as a serious problem that threatens public health by causing chronic respiratory diseases and skin aging. The present study was performed to investigate the inhibitory effects of Gryllus bimaculatus (the two-spotted cricket), which has recently attracted attention as an edible insect in South Korea, on DFD-induced aging and inflammation. Methods: To verify that DFD causes skin aging and investigate the anti-aging effect of an aqueous ethanolic-Gryllus bimaculatus extract (AE-GBE), human diploid fibroblasts (HDF) were treated with 100 μg/mL of European reference material (ERM)-CZ100 dust for 24 hrs in the presence or absence of 100 μg/ml AE-GBE. Aging and cellular toxicities were assessed by measuring reactive oxygen species (ROS) levels, DNA fragmentation, and β-galactosidase activity. The protein levels of cyclooxygenase (COX) 2, matrix metalloproteinase (MMP)-1, and collagen were measured by western blot, and the mRNA expressions of inflammationrelated genes were assayed by quantitative reverse transcriptase polymerase chain reaction. Results: Treatment with ERM-CZ100 induced an aged phenotype in HDF cells, as evidenced by increased ROS levels, DNA fragmentation, and senescence-associated β-galactosidase activity, but cotreatment with AE-GBE significantly reduced these inductions. The mRNA expressions of pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, induced by ERM-CZ100 were also reduced by AE-GBE cotreatment, which also reduced COX2 expression. Moreover, ERM-CZ100-induced MMP-1 expression and reduced collagen type I expression were recovered by AE-GBE treatment. Conclusion: These results suggest that AE-GBE is a potential treatment for domestic fine dust-induced skin inflammation and inflammaging.
