The levels of activity of cathepsin D were compared in neoplastic and normal gastric mucosa in 42 patients, aged 39-78, at different stages of the disease. A relationship was established between cathepsin D activity and main clinico-morphological characteristics of stomach tumor: cathepsin D activity was found to increase with decreasing differentiation and increasing depth of invasion and metastatic spreading of tumor tissue. Possible involvement of proteolytic enzymes and, in particular, an aspartyl proteinase--cathepsin D--in the mechanisms of invasion and metastatic spreading of neoplasms is discussed.

D002402 Cathepsin D An intracellular proteinase found in a variety of tissue. It has specificity similar to but narrower than that of pepsin A. The enzyme is involved in catabolism of cartilage and connective tissue. EC 3.4.23.5. (Formerly EC 3.4.4.23).
D005260 Female Females
D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.
