Abstract
Aims: To investigate the biological impact of simultaneous overexpression of lncRNA MEG3 and miR-155, termed a "double hit," on multiple myeloma (MM) cells compared to individual biomarker substitution.
Materials and methods: Human MM cells were transfected with MEG3-overexpressed plasmids and miR-155 mimics. Cell cytotoxicity, apoptosis, and gene expression were evaluated in transfected cells and clinical samples.
Results: MEG3 and miR-155 were significantly downregulated in MM patients, with lower expression levels correlating with advanced disease stages and poorer survival. Dual overexpression induced potent cytotoxic effects in MM cells.
Conclusion: MEG3 and miR-155 are potential tumor suppressors in MM. Simultaneous overexpression of both biomarkers could represent a novel therapeutic strategy, and their levels could serve as diagnostic and prognostic markers.
