Lactoferrin, an iron-binding glycoprotein found in high concentrations in human milk and other epithelial secretions and in the secondary (specific) granules of neutrophils, is thought to be responsible for primary defence against microbial infection, mainly as a result of lactoferrin sequestration of iron required for microbial growth. Many other functions(More)
Lactoferrin (Lf), the major iron-binding component of milk, also a major constituent of the specific granules of neutrophils involved in antimicrobial activity and a glycoprotein thought to play a role in regulatory functions in the hematopoietic system as well as other physiologic activities, is shown to occur in three isoforms. One, Lf-alpha, binds iron;(More)
Primary monolayer cultures of normal and malignant human mammary epithelial cells were tested for fibronectin by indirect immunofluorescence using antisera specific for fibronectin. This protein was not detectable on either the normal or malignant epithelial cells. Similar results were obtained for normal and malignant mouse mammary epithelial cell(More)
Mixtures of friend virus (CFV) and the regressing strain of friend virus (RFV) induce leukemia which regresses. The dominance of the regressing phenotype is solely a function of a threshold dose of RFV. The minimum amount of RFV which induced regression of CFV leukemia is below the titer for induction of friend disease, but does correlate ith the titer of(More)
The very rapid growth rate (1 population doubling/day) of normal human epidermal keratinocytes (HK) cultured in serum-free medium can be utilized for wound closure in burn treatment. However, rapid growth in vitro may present the possibility of neoplastic transformation. To investigate this possibility, HK were cultured from primary isolation to large(More)
In the present studies the effect of bilateral adrenalectomy on the pathophysiologic responses to recombinant human interleukin-1 alpha (rHIL-1 alpha) was determined in RIF-1 tumour models. Acute vascular injury and haemorrhagic responses were quantitated by the intra-tumour accumulation of 59Fe radiolabelled erythrocytes. In vivo clonogenic tumour cell(More)
The RFV strain of the Friend virus complex induces an erythroleukemia that spontaneously regresses. The tropism of regressing Friend virus complex (RFV), which is conferred by its helper MuLV component, MuLV-RF, is different from that of the conventional virus strain, CFV. RFV is NB-tropic and CFV is N-tropic. Passage of nonregressing CFV through Fv-1(More)
