Glutaredoxin-1, as a component of antioxidant system, plays a crucial role in pathogenesis of some cancers and pre-malignant lesions. The aim of this study is to assess salivary levels of glutaredoxin-1 in oral lichen planus (OLP) and oral squamous cell carcinoma (OSCC) patients compared with healthy controls.This cross-sectional study was conducted on 28 OLP patients, 20 OSCC cases, and 40 healthy subjects. Their salivary glutaredoxin-1 was assessed by the enzyme-linked immunosorbent assay (ELISA).Regarding the glutaredoxin-1 level, there was no significant difference between the three studied groups (p=0.073); however, the salivary glutaredoxin-1levels were higher in the healthy subjects than the OLP and OSCC patients. Among OSCC patients, the salivary glutaredoxin-1 levels were significantly higher in the males (p=0.03). According to glutaredoxin-1 levels, the difference between keratotic and non-keratotic OLP lesions were not significant (p=0.98). Furthermore, there was no significant difference between various clinical manifestations and grades of OSCC, (p=0.08, p=0.56, respectively).Salivary glutaredoxin-1 levels were lower in OLP and OSCC patients compared to the normal volunteers; therefore the role of glutaredoxin-1 in the pathogenesis of these diseases could be proposed. |
