Early pregnancy factor is not only a product of dividing embryonic and neoplastic cells, as demonstrated previously, but also of normal proliferating cells. Eight hours after partial hepatectomy in rats, early pregnancy factor was detected in serum. It rose to a peak by 48 hr. Neutralization of early pregnancy factor in vivo by passive immunization with(More)
Early pregnancy factor (EPF) has been identified as an extracellular homologue of chaperonin 10 (Cpn10), a heat shock protein that functions within the cell as a molecular chaperone. Here, we report the production of polyclonal antibodies directed against several different regions of the human Cpn10 molecule and their application to specific protein(More)
Early pregnancy factor (EPF) is a secreted protein, present in serum during early pregnancy and essential for maintaining viability of the embryo. It is a homologue of chaperonin 10 (Cpn10) but, unlike Cpn10, it has an extracellular role. EPF has immunosuppressive and growth regulatory properties. Previously we have reported the preparation of recombinant(More)
Early pregnancy factor (EPF) is a secreted protein with immunosuppressive and growth factor properties. During pregnancy, it appears in maternal serum within 6-24 h of fertilization, is present for at least the first two-thirds of pregnancy in all species studied and is essential for embryonic survival. It is a homologue of chaperonin 10, a heat shock(More)
Early pregnancy factor (EPF) is a secreted protein with immunosuppressive and growth factor properties that has been shown to suppress acute experimental autoimmune encephalomyelitis (EAE) induced with myelin basic protein (MBP) in Lewis rats. EAE is associated with infiltration of the central nervous system (CNS) with inflammatory cells. Spontaneous(More)
Early pregnancy factor (EPF) is a secreted protein with growth regulatory and immunomodulatory properties. It functions as an autocrine growth factor for tumour cells and as an autocrine or paracrine growth factor for regenerating normal cells. Anti-EPF antibodies have demonstrable anti-tumour activity and, as a result, hybridomas which produce such(More)
The results of a cytoplasmic oestrogen receptor assay in 134 cases of primary breast cancer are reported. Overall, 57% of primary cancers tested were oestrogen-receptor 'positive' (ER+) and attention is drawn to the need for careful initial handling of tumour tissue, to ensure an accurate assay result. ER+ tumours occurred more often and showed higher assay(More)
