Abstract
BACKGROUND
Calcium homeostasis is considered to be important in antineoplastic as well as in neurotoxic adverse effects of cisplatin.
AIMS
This study aimed to investigate the role of Ca(2+) in cisplatin neurotoxicity in cultured rat dorsal root ganglia (DRG) cells.
STUDY DESIGN
Cell culture study.
METHODS
DRG cells prepared from 1-day old Sprague-Dawley rats were used to determine the role of Ca(2+) in the cisplatin (10-600 μM) neurotoxicity. The cells were incubated with cisplatin plus nimodipine (1-3 μM), dizocilpine (MK-801) (1-3 μM) or thapsigargin (100-300 nM). Toxicity of cisplatinon DRG cells was determined by the MTT assay.
RESULTS
The neurotoxicity of cisplatin was significant when used in high concentrations (100-600 μM). Nimodipine (1 μM) but not MK-801 or thapsigargin prevented the neurotoxic effects of 200 μM of cisplatin.
CONCLUSION
Voltage-dependent calcium channels may play a role in cisplatin neurotoxicity.
