| In vitro | METHODS: SCC cells were treated with Inecalcitol (TX 522) (0.0008, 0.003, 0.012, 0.05, 0.2, 0.8, 3.2, 12.5 nM, 48 hours) and cell viability was measured by MTT assay. RESULTS Inecalcitol inhibited the growth of SCC cells in a dose-dependent manner with an IC50 of 0.38 nM. [1] METHODS: SCC cells were treated with Inecalcitol (TX 522) (1,10 nM), and Western Blot analysis was used to investigate the mechanism of inecalcitol-induced apoptosis. RESULTS Inecalcitol-treated SCC cells resulted in increased activity of caspase 8, 10, and 3, indicating that inecalcitol promotes apoptosis by activating the extrinsic pathway mediated by caspase 8/10 and caspase 3. [1] |
| In vivo | METHODS: Inecalcitol (TX 522) (1.3 mg/kg, intraperitoneal injection, 3 times a week) was used to treat mice bearing LNCaP cell tumor xenografts. Tumor size was measured and calculated, and blood was collected to measure serum calcium levels. RESULTS Inecalcitol-treated mice bearing tumor xenografts had a significant reduction in tumor size. The half-life of plasma Inecalcitol was 18.3 minutes. [2] |
