Although PTC generally exhibits favorable prognosis, a subset of patients experiences aggressive progression and increased mortality. Current prognostic approaches, reliant on clinic-pathological factors, have limitations, underscoring the need for innovative biomarkers. MicroRNAs (miRs) have emerged as promising candidates due to their roles in cellular processes and cancer progression.

Dual-luciferase assays confirmed that miR-18b directly targeted the 3'-untranslated region of <i>CDK2</i> and suppressed the expression of <i>CDK2</i>.
