We have previously shown overexpression of p53 and rearrangement of the p53 gene in AK-5 tumour. In order to study the role of p53 in AK-5 tumourogenicity, we introduced wild-type p53 in AK-5 cells. We have shown suppression of tumourogenicity in AK-5 cells after transfixion with wt p53. In one of the transfected clones 3B4, there was complete loss of tumour forming ability. Clone 3B4 also showed cellular aggregation which correlated well with the higher expression of cell adhesion molecules like fibronectin and hyaluronectin. These observations demonstrate tumour suppression in AK-5 after introduction of wt p53.
