Haptoglobin in lung defence

Haptoglobin (Hp) has been known to be associated with the host defence response to infection and inflammation. The biological functions of Hp can be related to its ability to bind haemoglobin or to modulate immune response. Hp is expressed at a high level in lung cells, yet its protective role(s) in the lung is not known. Using transgenic mice overexpressing Hp, we demonstrated that Hp can reduce blood-induced lung injury. Hp-mediated haemoglobin catabolism in lung cells appears to be linked to iron mobilization, and may be an efficient mechanism to reduce oxidative damage associated with haemolysis.

The acute phase protein haptoglobin and its relation to oxidative status in piglets undergoing weaning-induced stress

Haptoglobin (Hp) prevents the hemoglobin driven generation of hydroxyl radicals and lipid peroxides. Hp can reduce the neutrophil respiratory burst and is an antioxidative molecule in its own right. We aimed to evaluate Hp concentrations, oxidative stress and antioxidative capacity in blood during weaning and to characterise potential relationships between these parameters. Two batches of 10 piglets each (2 trials) weaned at the age of 27-30 days were fed a starter feed mix ad libitum. Blood samples were taken 1 week before weaning and at weekly intervals thereafter. Oxidative stress was monitored via the D-ROM system, antioxidative capacity was measured with the TEAC assay and Hp concentrations were measured by ELISA. Neutrophil phagocytic activity and oxidative burst were examined via flow-cytometry. Body weights were recorded weekly. Hp concentrations were increased in both trials post-weaning (P < 0.01); oxidative stress and oxidative burst were elevated in trial I (P < 0.005). In trial I, Hp and ROM values returned to baseline levels at 6 weeks post-weaning. The piglets in trial II showed respiratory symptoms and maintained elevated Hp concentrations. ROM values and Hp were related (r = 0.58; P < 0.01). Hp and body weight gain were inversely related post-weaning.     

Haptoglobin polymorphism among Saharian and West African groups. Haptoglobin phenotype determination by radioimmunoelectrophoresis on Hp O samples.

The haptoglobin (Hp) polymorphism is investigated in 11 African groups living in an area from the Algerian Sahara to Central Africa. More than 4,000 samples were examined. In the Saharian samples, the Hp1 gene frequency is higher than in any other African group. From north to south, a decrease in the Hp1 gene frequency is observed; in the Pygmy sample only, this frequency is lower than the frequency of the Hp2 gene. By means of a sensitive radioimmunoelectrophoresis, the presence of a residual Hp in Hp O sera in which the Hp polymorphism can also be determined can be revealed. Absence of Hp 1-1 and significant excess of Hp 2-2 individuals were observed. More Hp 2-1M phenotypes were detected in the Hp O population than in the non-Hp O population examined. In the Hp O samples, the influence of the phenotype distribution on the Hp gene frequencies is discussed. The heavy polymers of the Hp related to the presence of the alpha 2 chain (Hp2 gene product) are involved only in the biological mechanisms responsible for the presence of Hp O and Hp 2-1 M phenotypes among African groups.     

The Haptoglobin β chain as a supportive biomarker for human lung cancers

Haptoglobin (Hp) is produced as an acute phase reactant during inflammation, infection, malignant diseases, and several cancers. In proteomics analysis using human blood samples, the Hp peptide levels were about 3-fold higher in lung cancer patients versus normal individuals. This study is aimed at analyzing the elevation of which chain of Hp is closely related to lung cancers and can be a serum biomarker for lung cancers. In Western blot (WB) analysis, we found that the Hp β chain can be a better diagnostic biomarker for lung cancers. In the result of the Hp β chain ELISA developed by us, the concentrations of the Hp β chain in the sera increased about 4-fold in 190 lung adenocarcinoma patients versus 190 healthy controls (8.0 ± 3.8 μg ml(-1)vs. 1.9 ± 1.2 μg ml(-1)). ELISA data showed that the serum levels of the Hp β chain in breast cancer (1.5 ± 0.5 μg ml(-1)) and hepatocellular carcinoma (HCC) (1.4 ± 1.0 μg ml(-1)) patients remained similar to those of healthy controls. Compared to lung adenocarcinoma, the Hp β chain levels in the plasma of patients with other respiratory diseases such as tuberculosis (TBC), idiopathic pulmonary fibrosis (IPF) and bronchial asthma (BA) were closer to those of healthy controls. Our data suggest that an increase of the Hp β chain can be a potential serum biomarker for lung cancers.     

The role of the host versus the environment in duodenal ulcer disease.

Gastric functions can be understood only in the context of a network including the brain gut axis, neuro-endocrine and paracrine mechanisms and growth factors. These host factors including parietal cell sensitivity (PCS) may well interact with an important environmental factor, Helicobacter pylori (Hp), and help to explain its actions. The aim of this study was to investigate PCS related to Hp status and duodenal ulcer (DU). PCS was assessed by constructing dose-response curves after pentagastrin and calculating the D50. Five groups of patients were studied: I) active DU, Hp pos. (8); II) history of DU, Hp pos. (8); III) asymptomatic Hp pos. (8); IV) asymptomatic Hp neg. (10); V) DU on maintenance H2 blocker therapy, Hp pos. (20). PCS was repeated after Hp eradication. PCS was lowest in group IV, and in Hp pos. groups, was significantly higher, with insignificant differences among them, irrespective of DU. PCS declined significantly after Hp eradication. Group V showed an insignificant decline in PCS during treatment, not preventing recurrence. A higher PCS in Hp infection irrespective of DU, declining after eradication, suggests that this may be a reversible epiphenomena related to Hp infection. This may offer an explanation as to why DU develops only in some subjects with Hp, suggesting the importance of the host in the pathogenesis of DU.     

幽门螺旋杆菌感染与胃癌中Shh和C-myc表达的关系

为了探讨胃癌中幽门螺旋杆菌(Hp)感染和Sonic Hedgehog(Shh)、C-myc表达,它们之间的相关性以及胃癌发生的可能机制,采用免疫组化法检测89例胃癌组织及20例正常胃上皮组织中Shh及C-myc的表达。并采用快速尿素酶试验,组织病理学检测两种方法检查Hp。实验结果显示,胃癌组织Shh的表达要明显高于正常上皮组织,二者之间有显著差异(P<0.05);胃癌组织C-myc的表达水平也高于正常胃上皮组织,二者之间有显著差异(P<0.05);Hp阳性的C-myc阳性表达率明显高于Hp阴性,二者之间有显著差异(P<0.05);Shh表达阳性率在Hp阳性和阴性胃癌中无显著差异(P>0.05)。结果提示,胃癌的发生与癌基因Shh及C-myc的过度表达有关,Hp感染的致癌机制中可能有癌基因C-myc参与。     

Glycosylation of alpha-1-proteinase inhibitor and haptoglobin in ovarian cancer: evidence for two different mechanisms

The change in glycosylation of the two acute-phase proteins, alpha-1-proteinase inhibitor (API) and haptoglobin (Hp), in progressive ovarian cancer is different. This has been shown by monosaccharide analysis and lectin-binding studies of proteins purified from serum. In the glycan chains of API, there is decreased branching (more biantennary chains), less branches ending in alpha 2-3 sialic acid, more branches ending in alpha 2-6 sialic acid and more fucose, probably linked alpha 1-6 to the core region. On the other hand, Hp shows increased branching (more triantennary chains), more branches ending in alpha 2-3 sialic acid, less branches ending in alpha 2-6 sialic acid, and more fucose, probably in the alpha 1-3 linkage at the end of the chains. This is surprising because API and Hp are thought to be glycosylated by a common pathway in the liver. We have also shown that the fucose-specific lectin,lotus tetragonolobus, extracts abnormal forms of both Hp and API in ovarian cancer, but the expression of this Hp is related to tumour burden and the expression of this API is related to lack of response to therapy. It is suggested that this difference in the behaviour of API and Hp in ovarian cancer may be associated with the different changes in their glycosylation. Of the many mechanisms that could explain these findings, a likely one is that a pathological process is removing API with triantennary chains from the circulation. In addition to their normal roles (API-enzyme inhibitor and Hp-transport protein) these proteins are reported to have many other effects in biological systems, such as immunosuppression. As correct glycosylation of API and Hp is required for their normal stability/activity, changes in glycosylation could affect their functions in ovarian cancer and these modifications could alter the course of the disease.

Abstract

Haptoglobin (Hp) prevents the hemoglobin driven generation of hydroxyl radicals and lipid peroxides. Hp can reduce the neutrophil respiratory burst and is an antioxidative molecule in its own right. We aimed to evaluate Hp concentrations, oxidative stress and antioxidative capacity in blood during weaning and to characterise potential relationships between these parameters. Two batches of 10 piglets each (2 trials) weaned at the age of 27–30 days were fed a starter feed mix ad libitum. Blood samples were taken 1 week before weaning and at weekly intervals thereafter. Oxidative stress was monitored via the D-ROM^® system, antioxidative capacity was measured with the TEAC assay and Hp concentrations were measured by ELISA. Neutrophil phagocytic activity and oxidative burst were examined via flow-cytometry. Body weights were recorded weekly. Hp concentrations were increased in both trials post-weaning (P < 0.01); oxidative stress and oxidative burst were elevated in trial I (P < 0.005). In trial I, Hp and ROM values returned to baseline levels at 6 weeks post-weaning. The piglets in trial II showed respiratory symptoms and maintained elevated Hp concentrations. ROM values and Hp were related (r = 0.58; P < 0.01). Hp and body weight gain were inversely related post-weaning.     

Hematoporphyrin ethers--III. Cellular uptake and photosensitizing properties

1. The cellular uptake and the efficiency in sensitizing cells to photoinactivation were determined for hematoporphyrin (Hp) diphenyl ether, Hp dicyclohexyl ether and Hp dihexyl ether. 2. The phenyl diether was taken up by the cells to the same degree as was the clinically used porphyrin preparation photofrin II, while the dihexyl and notably the dicyclohexyl ether were taken up 3-4 times better. 3. Furthermore, the quantum yields for photoinactivation of cells were similar for the three diethers and twice as large as that for photofrin II. 4. Fluorescence- and absorption spectroscopy indicate that these findings are related to the fact that photofrin II is much more aggregated in the cells than are the three Hp diethers. 5. When cells loaded with the porphyrins are incubated with porphyrin-free medium containing serum a certain percentage of the cell-bound drug is removed: 14% for photofrin II, 28% for Hp diphenyl ether, 50% for Hp dicyclohexyl ether and 20% for Hp dihexyl ether. 6. With respect to cell uptake and retention of the dyes, the data did not show any uniform relationship to the polarity of the drugs, in contrast to what has been found earlier for Hp diethers of linear hydrocarbons.
