Expression levels and network analysis of inflammamiRs in peripheral blood mononuclear cells exposed to DDE “in vitro”

Zusammenfassung: | Recent studies have demonstrated that dichlorodiphenyldichloroethylene (DDE) induced a pro-inflammatory condition in peripheral blood mononuclear cells (PBMC). However, the molecular mechanisms implicated in this condition are poorly understood. Therefore, this study aimed to evaluate miR-155, miR-126, and miR-21 expression levels in PBMC exposed “in vitro” to DDE. PBMC were dosed with increasing concentrations of DDE (10–80 µg mL-1) at different treatment times (0–24 h). The results showed an up-regulation in the expression levels of assessed miRNAs (miR-155, miR-146, and miR-21) after PBMCs were exposed to DDE. Besides, bioinformatic analysis was performed to understand the biological roles of assessed miRNAs. The bioinformatic analysis shows that assessed miRNAs are associated with regulating signaling pathways involved in cancer, apoptosis, cell cycle, inflammation, metabolism, etc. These findings offer new insights into the molecular mechanisms related to the inflammatory processes and their regulation induced by DDE in PBMC exposed “in vitro”.
•Epigenetic changes (miRNAs dysregulation) were found in PBMC exposed to DDE.•InflammamiRs (miR-21, miR-146, and miR-155) were up-regulated in PBMC exposed to DDE.•Dysregulated miRNAs are related with different signaling paths linked to inflammation. |
