The effects of retinol, all-trans-retinoic acid, isotretinoin and etretinate on the activity of basement membrane collagen degrading enzyme was studied in melanoma cells. The results indicated that retinoids at concentrations of up to 10(-6) M did not significantly affect type IV collagenolytic activity in these cells in vitro. Since type IV collagenolytic enzyme may be involved in the metastatic potential of tumour cells, it appears that retinoids do not affect the metastatic potential of melanoma cells by affecting type IV collagenolytic activity.
