Archivio istituzionale della ricerca dell'Università degli Studi di Palermo
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, pubblicazioni, progetti, attività) adottato dall’Università di Palermo, e ha lo scopo di raccogliere, conservare, documentare, e diffondere ad accesso aperto le informazioni relative alla produzione scientifica degli autori afferenti all’Ateneo.
EnglishThe serum levels of lysosomal cathepsin B and L and Stefin A, an intracellular inhibitor of these proteolytic enzymes, were determined in patients with hepatocellular carcinoma (HCC) and/or liver cirrhosis (LC) and correlated with some clinical and biochemical parameters of these diseases. Cathepsin B serum levels were increased in HCC and in LC patients as compared to normal subjects (p < 0.001). However no difference was observed between HCC and LC groups. Interestingly, a significant relationship was evidenced between cathepsin B serum content and the grade of severity of cirrhosis (r = 0.41; p < 0.001). Cathepsin L was significantly elevated only in sera of cancer patients as compared to normal subjects or LC patients (p < 0.001) and significantly correlated with the number of malignant lesions (r = 0.49; p = 0.001). Stefin A serum levels were increased in HCC and LC patients as compared to healthy subjects (p < 0.02). However, these levels were significantly higher in the LC group as compared to the HCC group (p < 0.05). In cancer patients, a significant relationship was observed between Stefin A serum content and tumor size (r = 0.35; p < 0.05), number of neoplastic lesions (r = 0.556; p < 0.001) and serum a-fetoprotein (r = 0.38; p < 0.01). These data suggest that cathepsin B and L and Stefin A may be potentially useful as additional biochemical parameters to monitor the therapeutic response of these diseases to clinical treatments and to identify patients with cirrhosis developing precancerous lesions. © 1997 S.

| Abstract: | The serum levels of lysosomal cathepsin B and L and Stefin A, an intracellular inhibitor of these proteolytic enzymes, were determined in patients with hepatocellular carcinoma (HCC) and/or liver cirrhosis (LC) and correlated with some clinical and biochemical parameters of these diseases. Cathepsin B serum levels were increased in HCC and in LC patients as compared to normal subjects (p < 0.001). However no difference was observed between HCC and LC groups. Interestingly, a significant relationship was evidenced between cathepsin B serum content and the grade of severity of cirrhosis (r = 0.41; p < 0.001). Cathepsin L was significantly elevated only in sera of cancer patients as compared to normal subjects or LC patients (p < 0.001) and significantly correlated with the number of malignant lesions (r = 0.49; p = 0.001). Stefin A serum levels were increased in HCC and LC patients as compared to healthy subjects (p < 0.02). However, these levels were significantly higher in the LC group as compared to the HCC group (p < 0.05). In cancer patients, a significant relationship was observed between Stefin A serum content and tumor size (r = 0.35; p < 0.05), number of neoplastic lesions (r = 0.556; p < 0.001) and serum a-fetoprotein (r = 0.38; p < 0.01).
