Abstract: | Saline extraction of tumor cells from YC8 lymphoma transplanted in Balb/c Mice, of lymphocytes from animals bearing this tumor and of lymphocytes from control animals, allowed us to show important hydrolytic activities towards UDP-(14C)]-galactose and galactose-(14C)]-1-phosphate in normal lymphocytes. These activities disappear in lymphocytes from Mice bearing this tumor and in tumor cells themselves. |
