Protective Effect of Transferrin C3 in Lung Cancer?

- Abstract
In a previous study of lung cancer patients and controls from the Stockholm area in central Sweden, we found a significantly decreased frequency of the transferrin (TF) variant C3 in small cell and squamous epithelial lung cancer but not in adenocarcinoma, suggesting a protective effect of TF C3 in small cell and squamous lung cancer. In an attempt to replicate this association we studied TF types in lung cancer patients and controls from two additional Swedish subpopulations, viz. northern Sweden and southwestern Sweden. We were able to confirm the significantly decreased frequency of TF C3, especially in small cell lung cancer, in northern Sweden but not in southwestern Sweden. Thus the eventual protective effect of TF C3 in small cell lung cancer is an open question. We hypothesize that the association between TF C alleles and lung cancer may be secondary and dependent on linkage disequilibrium with allelic variants of newly discovered tumor-associated genes known to map to the same position (3q21) as TF, e.g. NCK and H-RYK.
