Abstract

Development of resistance to cisplatin (cDDP) is a major obstacle in the cure of many cancers. Recently, a cDNA from cDDP-resistant human ovarian carcinoma cells was identified as the mitochondrial hsp60 chaperonin. The aim of this study was to determine the changes in expression of hsp60 during selection for cDDP resistance in two head and neck cancer cell lines, UMSCC5 and UMSCC10b and whether the emergence of resistance could be correlated with the level of hsp60 expression. We have selected cDDP-resistant variants of two squamous cell carcinoma cell lines, the UMSCC5 and UMSCC10b with levels of resistance varying from 1.5 to 6-fold. Concomitant with the emergence of resistance, the basal level of hsp60 increased 2 to 3-fold. In addition, less cDDP resistance as well as lower hsp60 levels were detected in cDDP resistant variants of the UMSCC10b cell line when selected in the presence of tamoxifen, suggesting a correlation between the intrinsic level of hsp60 expression and cDDP resistance. Using linear regression analysis both UMSCC5 and UMSCC10b cell lines demonstrated a high degree of correlation with coefficients of 0.91 and 0.90, respectively. In conclusion, the expression of hsp60 was closely related to the development of cDDP resistance and could be used as a marker for the emergence of cDDP resistance.
