Arsenic is shown to inhibit DNA maintenance by inhibiting poly ADP-ribose polymerase one (PARP-one), a liable enzyme for DNA split mend procedures (Ding et al., 2009). Resistance to apoptosis due to heavy metals exposure breaks down a simple cell defense. It has been proven that Cd can induce malignant transformation with the prostate epithelial mobile line as a result of elevated apoptotic resistance. Apoptotic resistance is attributed for the overexpression of Bcl-2 and disruption of a certain pathway of apoptosis generally known as the JNK pathway (Qu et al.
