Abstract:
Background: Cisplatin is an effective synthetic chemotherapeutic drug used for cancer
treatment. Vitamin B12 has been shown to possess anti-genotoxic activity. This study aimed to investigate
the effect of vitamin B12 on chromosomal damage induced by cisplatin.
Methods: The level of sister chromatid exchanges (SCEs) and chromosomal aberrations (CAs)
were measured in cultured human blood lymphocytes treated with cisplatin and/or vitamin B12.
Results: The results showed a significantly elevated frequency of CAs and SCEs of cisplatin-treated
cultures compared to the control (P < 0.05). The CAs and SCEs induced by cisplatin were significantly
lowered by pretreatment of cell cultures with vitamin B12. In addition, cisplatin caused
a slight reduction in the mitotic index (MI), while vitamin B12 did not modulate the effect of cisplatin
on MI.
Conclusion: Vitamin B12 can protect human lymphocytes against genotoxicity associated with
cisplatin.
