WiDr cells from a human colon adenocarcinoma cultivated in vitro express the calcium binding protein calretinin. The immunoreactivity is present in some interphasic cells and decreases after seven days in culture together with the augmentation of the cell number. Calretinin expression is maintained in the undifferentiated cells of the tumoral mass developed in nude mice and in recultivated isolated tumour cells from the xenograft. From the experiments here described, the protein expression is quantitatively influenced in vitro by the addition of drugs, such as colchicine and taxol, which intervene in cytoskeleton organisation. The percentage of the calretinin immunoreactive cells increases after the addition of colchicine to the medium while the immunoblot analysis shows a higher calretinin content in the cells treated with taxol. |
