We have also shown that cisplatin cross-links nuclear matrix-associated transcription factors and cofactors to DNA in the MCF-7 human breast cancer cell line (5). WebThe platinum compounds cross-link DNA strands, thereby inhibiting DNA synthesis and function. If the DNA is damaged enough, the cell will undergo apoptosis ( Figure 20-5 ). The platinum compounds enter cells through an active transporter. On entering the cell, the Cl − ions dissociate, leaving behind a reactive complex that interacts with DNA. chip forge and brazing hearth
