Özet

This research aims to examine the impact of programmed cell death 4 (PDCD4), microRNA-21 (miR-21) and microRNA-208a (miR-208a) transcripts, and protein levels on oral epithelial dysplasia (OED) development in oral squamous cell carcinoma (OSCC). Methods: The research investigation involved the collection of saliva, blood, and tissue samples from a total of 20 patients diagnosed with OSCC, 15 patients diagnosed with OED, and 15 healthy individuals. PDCD4, miR-21, and miR-208a expression was performed by quantitative reverse transcription polymerase chain reaction (qRT-PCR). PDCD4 protein levels were assessed using enzyme-linked immunosorbent assay (ELISA) in both saliva and blood samples. For statistical analysis, the Kruskal–Wallis test and the Spearmen rank test were utilised. Results: PDCD4 expression levels were considerably lower in patients with OSCC and OED (p < 0.05) in three biological samples. In contrast, miR-21 expression was higher in OED and OSCC patients. Patients with low PDCD4 mRNA levels and strong miR-21 expression had a significant connection (p < 0.05) with tumor size and depth. Conclusions: Examining PDCD4 and miR-21 transcript levels may help detect the transition from OED to OSCC. This work suggests that PDCD4 and miR-21 expression levels in liquid biopsies may be biomarkers for OED monitoring in the future.
