The purpose of this study was to correlate abnormalities in chromosome 14 with the invasive metastatic phenotype of K-1735 murine melanoma cells. Low metastatic K-1735 clone 10 and clone 23 cells were transfected with either basic fibroblast growth factor (bFGF), Kaposi's fibroblast growth factor (kFGF), or c-H-ras gene. A high number of bFGF- and H-ras-transfected cells exhibited chromosome 14 rearrangements. These cells also had increased expression of collagenase IV. The kFGF transfected cells were highly metastatic but did not have increased expression of collagenase type IV, nor abnormalities in chromosome 14. The data imply that karyotypic changes in chromosome 14 are associated with increase expression of collagenase type IV.
