We found that only the KLF10 gene shows in colon cancer cells a genomic VDR binding site, i.e. there is not much evidence that these four markers genes are primary VDR targets with a global expression profile as reported here for CD14 and THBD. Therefore, the expression changes of the four described genes probably cannot be used for a similar type of categorization as performed in this study with CD14 and THBD. This evidence concerns the gene KLF10 and colonic neoplasm.
