Inhibition of DNA processing in heavy metal carcinogenesis
This untangles the DNA releasing the DNA spine again. Since the chemical composition of the DNA remains the same, the untangled DNAs are chemical isomers. Therefore, topoisomerases are isomerase enzymes which work on the DNA topology.The N-terminal domain is then preceded by a highly conserved, 421 amino acid core domain that contains all of the catalytic residues except the active site tyrosine. A protease-sensitive and poorly conserved linker domain comprising 77 amino acidsconnects the core

Immunotherapy in ovarian cancer
If the immune system identifies the differences in the cells of the transplanted organ, then the immune system will attack the host cells and the rejection rate will be very high and destructive to the patient. (Mantovani and Sica 2010). The presence of a single foreign gene in the transplant may make the own immune system to identify as a cancer cell and destroy it. Chemotherapy is used in combination with the organ transplant, but the survival rate is not high. Many drugs are being tried to
