Impact of High-Risk HPV Infection on PI3K, MALAT1, H19 and LINC00460 Expression in Cervical Cells

High-risk human papillomavirus (HPV) is a central factor in cervical cancer development, largely due to its E6 and E7 oncoproteins that disrupt normal cellular regulation. This study explored the influence of high-risk HPV on the expression of PI3K and the long non-coding RNAs (lncRNAs) MALAT1, H19 and LINC00460 in cervical cells. Using a case-control design, cervical liquid samples from 50 HPV-positive patients and 20 healthy controls were analysed via quantitative real-time PCR, with statistical methods employed to assess correlations between viral oncoproteins and target gene expression. Results demonstrated a significant upregulation of PI3K (24.59-fold change, p < 0.036), MALAT1 (9.75-fold change, p < 0.005), LINC00460 (1.15-fold change, p < 0.013) and H19 (7.1-fold change, p < 0.018) in HPV-infected samples, indicating their potential role in HPV-mediated oncogenesis. Although correlation analysis revealed trends between E6/E7 and certain lncRNAs, these were not statistically significant. Overall, these findings deepen our understanding of the molecular changes linked to high-risk HPV infections and identify PI3K, MALAT1 and H19 as promising biomarkers and therapeutic targets for cervical cancer. Future studies should further investigate these interactions to enhance early detection and improve treatment strategies for HPV-associated malignancies.
