Abstract

Aquatic pollutant Malachite green (MG) induces oxidative stress by producing intracellular H2O2 and associated hydroxyl, hydroxymethyl or hydroperoxide radicals in Saccharomyces cerevisiae. These radicals disturb cellular functions leading to early aging. Exogenous supply of natural antioxidants may play a crucial role as anti-aging by ensuring the cellular survival. Protective effect of Chebulinic acid (CA) and Boeravinone B (BB) was biochemically evaluated by measuring the expression levels of antioxidant enzymes. Intracellular oxidants generation, nuclear damage, necrosis, apoptosis, reduction in caspase 3/7 activity studied microscopically, spectrofluorometrically and biochemically along with growth dynamics and relative quantitation of Yap1, Sir2 and Bir1 expression using RT-PCR. Malachite green (MG) showed adverse effect on S. cerevisiae showing 400.83% enhancement in accumulation of intracellular H2O2 and associated hydroxyl, hydroxymethyl or hydroperoxide radicals. Independent supplementation of CA (5 μg/ml) and BB (3 μg/ml) significantly reduced the accumulation by 385.78 and 372.68%, respectively. Presence of MG extended the lag phase of growth curve and also reduced colony forming units (CFUs)/ml to 3 × 108 from 15 ×...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
