The initiative role of XPC protein in cisplatin DNA damaging treatment-mediated cell cycle regulation.

XPC is an important DNA damage recognition protein involved in DNA nucleotide excision repair. We have studied the role of the XPC protein in cisplatin treatment-mediated cell cycle regulation. Through the comparison of microarray data obtained from human normal fibroblasts and two individual XPC-defective cell lines, 486 genes were identified as XPC-responsive genes in the cisplatin treatment (with a minimal 1.

Defining the function of xeroderma pigmentosum group F protein in psoralen interstrand cross-link-mediated DNA repair and mutagenesis.

Many commonly used drugs, such as psoralen and cisplatin, can generate a very unique type of DNA damage, namely ICL (interstrand cross-link). An ICL can severely block DNA replication and transcription and cause programmed cell death. The molecular mechanism of repairing the ICL damage has not been well established.

Defining the function of XPC protein in psoralen and cisplatin-mediated DNA repair and mutagenesis.

DNA damage recognition plays an important role in DNA repair and mutagenesis. Failure to recognize DNA damage may lead to DNA replication without damage repair as well as mutation accumulation. Mutations can lead to many disease conditions.
