Assessment of the Cytotoxicity Mechanism of Diazinon on HFFF2 Cells: A Bioinformatic and Experimental Study

Pesticide exposure can cause many skin diseases such as hypopigmentation and contact dermatitis, but the underlying mechanisms remain unclear. Furthermore, Organophosphate pesticides (OPs) including Diazinon (DZN) can affect cellular pathways like ATPase, leading to mitochondrial energy deficit and even apoptosis in the cell's functions. Following cell exposure to the OP pesticide DZN through treatment, we evaluated alteration in gene expression and DNA damage. Bioinformatic analysis was performed based on the AutoDock, Protein Data Bank, STRING, Way2Drug, and Comparative Toxicogenomics databases and tools. The MTT assay, wound healing, DAPI staining, flow cytometry, and real-time PCR were applied in the current study. The results showed that the viability and migration capacity of HFFF2 cells decreased, and the apoptosis rate increased in the DZN-treated group. These findings revealed that DZN regulated the expression of the apoptotic genes in DZN cells.
