The CYFRA 21-1 assay which detects the cytokeratin 19 (CK19) fragment is widely used as a tumor marker for lung cancer. We previously suggested that the failure of PCR amplification of exon 1 is closely related to the inability of the expression of mRNA for CK19, and hypothesized that point mutations might exist within exon 1. In order to prove this, sequence analysis of the promoter region and exon...
The CYFRA 21-1 assay which detects cytokeratin 19 (CK19) fragment is widely used as a tumor marker for lung cancer. However, the reason why some lung cancer cell lines release CK19 fragment in culture supernatants and others do not, remains unclear. It was hypothesized that the release of CK19 fragment may be elucidated by the expression of mRNA for CK19. In order to prove this, the mRNA for CK19...
