Using both PrimerF2 and PrimerR2 (Fig 1B), CD44V (v8-v10) which may represent total amounts of variants in a single band were strongly expressed in CRC cell lines except LOVO cells, which deemed consistent with CD44 Variants made by primerF1/primerR1 (middle panel of Fig 1C). This evidence concerns the gene CD44 and colorectal carcinoma.
