Metformin and 2-Deoxy-d-glucose synergistically inhibit the viability of thyroid papillary carcinoma with BRAF mutation by ROS-dependent PI3K/AKT signaling pathway.

The aim of this study was to explore the molecular mechanism through which metformin combined with 2-deoxy-d-glucose (2-DG) decreases the viability of BCPAP thyroid papillary carcinoma cells. BCPAP cells were treated with only metformin, only 2-DG, and both metformin and 2-DG. We used the CCK-8 assay to assess cell viability, dichlorofluorescein staining to detect reactive oxygen species (ROS), and western blot analysis to quantify protein expression.
