Abstract

1. The specific activities of sialytransferase in metastatic tumor sites were 5-37% of those of uninvolved non-cancerous tissue. The non-cancerous host tissues had a slightly lower average sialyltransferase activity than that of non-pathological control livers (986 vs 1194 dpm/min/mg protein). 2. The levels of total and bound sialic acid are increased 1.4 to 7.2-fold in homogenates, supernatants and resuspended pellets of metastatic tumor sites compared to non-cancerous and non-pathological control livers. For all these tissues, 24-29% of the bound sialic acid is found on soluble components (in the 16,300 g supernatant). 3. Soluble sialoglycoconjugates from most metastatic tumor sites give gel filtration profiles different from those of non-cancerous and non-pathological control livers.
