AbstractBackground: Cervical cancer is the fourth most common cancer among women. In recent years, significant progress has been made in its treatment. Quercetin, a polyphenolic compound found in flavonoid-containing plants, is of interest due to its potential therapeutic effects. miR-21 plays a crucial role in cervical tumor metastasis by activating pathways related to invasion and migration, while miR-34a-5p is essential in regulating epithelial-to-mesenchymal transition and preventing increased cell proliferation and migration. The findings of this study could provide insight into the role of quercetin in cancer cells. Objectives: This study aims to investigate the effect of quercetin on the expression levels of miR-21 and miR-34a-5p in HeLa and Ca Ski cervical cancer cell lines. Methods: In this study, HeLa and Ca Ski cells were treated with quercetin. Cell viability and apoptosis were evaluated using the MTT assay and flow cytometry over a 48-hour period. Additionally, the effects of quercetin on the expression levels of miR-21 and miR-34a-5p were analyzed using qRT-PCR. Results: The study demonstrated that quercetin inhibited the viability of HeLa and Ca Ski cells and induced apoptosis in these cells. Quercetin suppressed cell viability with an IC50 of 102.9 μM for HeLa and 304.1 μM for Ca Ski cells after 48 hours. Quercetin down-regulated miR-21 in HeLa and Ca Ski cell lines by 2.5 ± 0.1 (P = 0.045) and 2.0 ± 0.2 (P = 0.016) fold, respectively. Additionally, miR-34a-5p increased by 3.3 ± 0.7 (P = 0.010) and 2.4 ± 0.8 (P = 0.047) fold after exposure to quercetin in HeLa and Ca Ski cell lines, respectively. Conclusions: Our study showed that quercetin has an anti-cervical cancer effect and can be used alongside standard therapies as a promising agent with fewer side effects in cervical cancer treatment.en
