  • Lizosomske cisteinske proteinaze, njihovi endogeni zaviralci in rak = Lysosomal cysteine proteinases, their endogenous inhibitors and cancer
    Strojan, Primož
    Lysosomal cysteine proteinases, termed also cysteine cathepsins, are ubiquitous proteolytic enzymes. The most important group of their endogenous inhibitors belongs to the cystatin superfamily, which ... consists of three families: stefins, cystatins and kininogens. The involvement of cysteine cathepsins and cystatins in proteolytic processes, leading to invasion and disseminiantion of tumor cells, has been confirmed by the results of several in vitro and in vivo studies. These findings suggested that they paly a role in the prognosis of the course of the disease and survival of cancer patients.The paper describes the biochemical properties of lysosomal cysteine proteinases and their endogenoous inhibitors, as well as the role they play inthe cell and in malignant tumor growth and dissemination. Cinical studies evaluating these new biological prognostic factors in cancer patients are reviewed. The results are encouraging, particularly for patients with breast cancer, but they are not yet conclusive enough to be applied in the daily clinical practice along with the already established prognostic factors.
