Sera from 25 metastatic breast cancer patients and 25 healthy controls were subjected to affinity chromatography using immobilized galectin-1. Serum from the healthy subjects contained on average 1.2 mg per ml (range 0.7-2.2) galectin-1 binding glycoproteins, whereas serum from the breast cancer patients contained on average 2.2 mg/ml (range 0.8-3.9), with a higher average for large primary tum...

The results indicate that haptoglobin may account for at least part of the inhibitor activity of plasma or serum. This seems to be consistent with the finding that administration of glucocorticoids in rats induced parallel changes in plasma inhibitor activity and haptoglobin concentration. However, no clear relationship between the haptoglobin concentration and the inhibitory actions of several...

BACKGROUND Allergic rhinitis (AR) is an allergic disorder of the nasal tissue that underlies diseases such as sinusitis, otits and asthma. Different predisposing factors including immunological and non-immunological factors contribute to the disease pathogenesis. OBJECTIVE To investigate association of haptoglobin (Hp) phenotypes (Hp1-1, 2-1 and 2-2) with serum immunoglobulins A and E levels ...

A method is described for the estimation of serum haptoglobin as ;haemoglobin-binding capacity'. The method relies on column chromatographic separation of the haemoglobin/haptoglobin complex from excess added free haemoglobin on the dextran gel Sephadex G.100. The method is simple and reproducible, and correlates well with another method of estimating haemoglobin-binding capacity over a wide ra...

BACKGROUND There is a marked difference in the degree of expression of the homozygous C282Y HFE genotype that is associated with hereditary hemochromatosis. It has been reported that individuals with the haptoglobin 2-2 type manifest increased iron concentrations, including serum iron, transferrin saturation, and ferritin. METHODS We studied 232 patients, 115 homozygous for the c.845G-->A (C2...

Altered glycosylation in glycoproteins is associated with carcinogenesis, and certain glycan structures and glycoproteins are well-known markers for tumor progression. To identify potential diagnostic candidate markers, we have developed a novel method for analysis of glycosylation changes of glycoproteins from crude serum samples using lectin-based glycoprotein capture followed by detection wi...

The physicochemical and biochemical properties of hemoglobin associated with haptoglobin were compared with those of hemoglobin bour,d by antihemoglobin antibody. The mechanism of enhanced peroxidase activity of hemoglobin bound by haptoglobin was concluded not to be activation but stabilization of hemoglobin at acidic pH by haptoglobin. Haptoglobin protects hemoglobin from denaturation by acid...
