Objective: This study examines if homeopathic drug Arsenicum Album 30C (Ars Alb 30C) can elicit ameliorative responses in yeast (Saccharomyces cerevisiae) exposed to arsenate.
Methods: The yeast S. cerevisiae 699 was cultured in a standard yeast extract peptone dextrose broth medium. It was exposed to the final concentration of 0.15 mmol/L arsenate for two intervals, 1 h and 2 h, respectively. The cell viability was determined along with the assessment of several toxicity biomarkers such as catalase (CAT), superoxide dismutase (SOD), total thiol (GSH) and glucose-6-phosphate dehydrogenase (G6PDH), lipid peroxidation, protein carbonylation and DNA damage. Reactive oxygen species (ROS) accumulation, expressions of relevant stress transcription activators like Yap-1 and Msn 2, and mRNA expression of yeast caspase-1 (Yca-1) were also measured.
Results: Treatment of arsenate increased lipid peroxidation, protein carbonylation, DNA damage, ROS accumulation and expressions of Yap-1, Msn 2 and Yca-1 and decreased GSH, G6PDH, CAT and SOD. Ars Alb 30C administration decreased lipid peroxidation, protein carbonylation, DNA damage, ROS formation and Msn 2 and Yca-1 expressions and increased cell viability, GSH, G6PDH, CAT and SOD significantly (P<0.05), except for a slight increase in Yap-1 expression.
Conclusion: Ars Alb 30C triggers ameliorative responses in S. cerevisiae exposed to arsenate.
