Application
Bleomycin is used in combination with Etoposide and Cisplatin to treat testicular, ovarian and cervical cancer. This combination is popular as BEP chemotherapy and has also been demonstrated as effective and most successful chemotherapy regimen in germ-cell tumors. Since it is a cytotoxic agent, bleomycin is known to induce endothelial damage the lung vasculature referred to as bleomycin-induced lung-injury or bleomycin-induced pneumonitis (BIP). Researchers have used this property of bleomycin to induce lung fibrosis in mouse and rat models.
Biochem/physiol Actions
Bleomycin sulfate binds to DNA, causes ssDNA scission at specific base sequences and inhibits DNA synthesis. This inhibitory action requires bleomycin to bind oxygen and a metal ion. It can also cleave RNA, to a lesser degree but more selectively. It acts as an inducer and regulator of apoptosis and inhibits tumor angiogenesis.
