In fact, dysregulation of Mg2+ homeostasis has been increasingly associated with the development and progression of cancer, particularly colorectal cancer (CRC) . Transient receptor potential melastatin (TRPM) channels, especially TRPM6 and TRPM7, are essential regulators of epithelial Mg2+ influx. While TRPM7 promotes CRC progression, the role of TRPM6 and TRPM6/  \n7 channels remains unclear.  \nAIM  \nTo investigate the role of membrane-localized TRPM6 and TRPM6/7 channels in Mg2+ influx, spheroid (SP) formation, stemness, and migration.  \nMETHODS  \nWe used parental and SP-derived HT-29 cells at comparable passages as in vitro models. Mass spectrometry confirmed full-length sequences, phosphorylation, and methionine oxidation of TRPM6 and TRPM7. Mg2+ influx, total and free Mg2+ levels were measured by fluorescence imaging and biochemical assays. TRPM6 / TRPM7 expression and markers were analyzed by western blot. Func-tionalassays, including secondary SP formation and wound healing, assessed stemness and migration.

Mass spectrometric analysis confirmed the presence of full-length TRPM6 and TRPM7 with increased phosphorylation and oxidation in SP cells. Enhanced Mg2+ influx and total intracellular Mg2+ levels were observed in SP cells. Free ionized intracellular Mg2+ levels remained comparable across all experimental groups.
