BACKGROUND: Thyroid cancer is ranked as the most common malignancy within the endocrine system and the seventh most prevalent cancer in women globally. Thyroid malignancies require evaluating biomarkers capable of distinguishing between them for accurate diagnosis. We examined both mRNA and protein levels of TSPAN1 in plasma and tissue samples from individuals with thyroid nodules to aid this endeavour.
METHODS: In this case-control study, TSPAN1 was assessed at both protein and mRNA levels in 90 subjects, including papillary thyroid cancer (PTC; N = 60), benign (N = 30), and healthy subjects (N = 26) using enzyme-linked immunosorbent assay (ELISA) and SYBR-Green Real-Time PCR, respectively.
RESULTS: TSPAN1 plasma levels were decreased in PTC and benign compared to healthy subjects (P = 0.002). TSPAN1 mRNA levels were also decremented in the tumoral compared to the paired normal tissues (P = 0.012); this drop was also observed in PTC patients compared to benign patients (P = 0.001). Further, TSPAN1 had an appropriate diagnostic value for detecting PTC patients from healthy plasma samples with a sensitivity of 76.7% and specificity of 65.4% at the cutoff value < 2.7 (ng/ml).
CONCLUSION: TSPAN1 levels are significantly reduced in patients with benign and PTC, demonstrating its potential value as a diagnostic biomarker. Additionally, the significant reduction in TSPAN1 mRNA expression within PTC tumor tissues may suggest its involvement in tumor progression and development. Further studies, including larger-scale validation studies and mechanistic investigations, are imperative to clarify the molecular mechanisms behind TSPAN1 and, ultimately, its clinical utility for treating thyroid disorders.
