ABSTRACT
AIM: Early cervical cancer diagnosis is a global challenge that needs to be addressed by the discovery of less invasive diagnostic and prognostic approaches. Circulating miRNAs are stable in plasma and their diagnostic potentials have been elucidated in some cancers. Therefore, in this cross-sectional study, we determined the patterns of expression of 7 selected circulating microRNAs that differ between patients with cervical cancer receiving therapy, patients with cervical not on therapy and healthy females. The goal was to investigate the diagnostic and prognostic potential of these selected miRNAs.
METHODS: Total RNA was extracted from plasma samples collected from 53 participants recruited from Komfo Anokye Teaching Hospital and the Cape Coast Teaching Hospital, Ghana. Complementary DNA (cDNA) synthesis was performed, followed by quantitative polymerase chain reaction (qPCR) to amplify and quantify the expression levels of the target microRNAs. Expression levels of seven microRNAs-hsa-miR-146a, hsa-miR-29a, hsa-miR-29b, hsa-miR-34a, hsa-miR-233, hsa-miR-155, and hsa-miR-27a were compared among three groups: healthy controls (n = 27), patients with cervical cancer on therapy (n = 13), and those not on therapy (n = 13).
RESULTS: miR-155 and miR-27a showed statistically significant differential expression between cancer patients and healthy controls. In addition, miR-29b expression levels differed significantly between stage 4b and stage 4a of patient with cervical cancer undergoing treatment.
CONCLUSION: These findings suggest that circulating plasma miRNAs may serve as non-invasive biomarkers for the early detection of cervical cancer, monitoring disease progression, and evaluating treatment response.
