✦ Synopsis

ABSTRACT

Inhibition of a cell‐surface proteinase can inhibit the growth of many normal human cell types in culture. Some tumour cells are also sensitive to proteinase inhibitors, but others are resistant, and continue to grow in the presence of these inhibitors. Here we describe two human tumour cell lines which convert from the sensitive to the resistant state. In one case, the conversion occurs during routine passaging, but, in the other, it is determined by growth conditions, and is reversible.

## Abstract The polyphenolic compounds curcumin and quercetin increased sensitivity of ovarian cancer cells (CAOV3 and SKOV3) to cisplatin. The effect was obtained when the compounds were added simultaneously with cisplatin, as well as when they were added 24 h before. High serum levels of certain
