Abstract
Factor Xβactivating activity (FXAA) was determined by a chromogenic assay in normal and malignant breast tissue. FXAA was found in all tissue (n = 38) irrespective of pathology, and the activity of normal tissue was similar to that of tumours. FXAA correlated with tissue hemoglobin in normal breast (p<0.02) but not in tumours. FXAA was markedly reduced by aluminium hydroxide, barium citrate, antiβhuman factor VII, DFP, PMSF and phospholipase C, but was unaffected by iodoacetamide and mercuric chloride. It is concluded that FXAA is a serine protease with the properties of a tissue factorβfactor VII complex. FXAA occurs in normal and malignant breast tissue, although the βnormalβ activity may be an artefact of the homogenization process.

Background. Some growth factors may promote tumor growth by affecting tumor angiogenesis. The angiogenic growth factor, pleiotrophin, was demonstrated previously in human breast carcinoma tissues; however, the pattern of pleiotrophin expression in normal breast tissues has not been established. Met
Cytogenetic and molecular studies have suggested that the 3p14.2 chromosome subband contains tumor suppressor genes involved in the pathogenesis of many types of human cancers. Recently, the FHIT (fragile histidine triad) gene was identified in this part of chromosome 3 as a candidate suppressor gen
