Natural compounds targeting miRNAs: a novel approach in oral cancer therapy

Abstract

Oral cancer (OC) is a significant global health issue, with high rates of both mortality and morbidity. Conventional treatments, including surgery, radiation, and chemotherapy, are commonly used, but they often come with serious side effects and may not fully eliminate cancer cells, resulting in recurrence and resistance to treatment. In recent years, natural products derived from plants and other biological sources have gained attention for their potential anticancer properties. These compounds offer advantages such as lower toxicity compared to traditional chemotherapy. Notable natural compounds like quercetin, berberine, curcumin, andrographolide, nimbolide, ovatodiolide, and cucurbitacin B have demonstrated effectiveness in inhibiting OC cell growth by targeting various signaling pathways involved in cancer progression. Recent breakthroughs in molecular biology have highlighted the crucial role of microRNAs (miRNAs) in the development of OC. Targeting dysregulated miRNAs with natural products offers a promising strategy for treating the disease. Natural compounds exert anticancer effects by influencing both altered cellular signaling pathways and miRNA expression profiles. This study aims to explore the role of miRNAs as potential molecular targets in OC and to investigate how natural products may regulate these miRNAs. Additionally, this review will shed light on the therapeutic potential of phytochemicals in modulating miRNA expression and their significance in OC treatment.
