Alternative splicing is a common natural tool for the inhibition of function of full length gene products. We explored whether there was evidence that alternative splicing of ERCC1 may serve such a function for nucleotide excision repair. The ratio of alternatively spliced species to full length species was assessed for the protein and/or for the mRNA, for a series of human cell lines and tissues. This ratio was plotted against the amount of cisplatin-DNA adduct repair in each cell line (n=9), as measured by atomic absorbance spectrometry. As the percentage of alternatively spliced protein and/or mRNA increased, the amount of cisplatin-DNA adduct that was repaired was reduced. This inverse relationship was associated with a substantial amount of scatter (r=0.635), particularly at low levels of repair. These data demonstrate an association between alternative splicing of ERCC1, and reduction in cellular capability to repair cisplatin-DNA adduct.

D011506 Proteins Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein. Gene Products, Protein,Gene Proteins,Protein,Protein Gene Products,Proteins, Gene
D002945 Cisplatin An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
