PGRP-S (Tag7) is an innate immunity protein involved in the antimicrobial defense systems, both in insects and in mammals. We have previously shown that Tag7 specifically interacts with several proteins, including Hsp70 and the calcium binding protein S100A4 (Mts1), providing a number of novel cellular functions. Here we show that Tag7–Mts1 complex causes chemotactic migration of lymphocytes, with NK cells being a preferred target. Cells of either innate immunity (neutrophils and monocytes) or acquired immunity (CD4+ and CD8+ lymphocytes) can produce this complex, which confirms the close connection between components of the 2 branches of immune response. 相似文献

Hemorrhagic fever with renal syndrome (HFRS) is a disease caused by viruses of the family Bunyaviridae,genus Hantavirus.HFRS from Dobrava virus (DOBV) is a seldom reported disease in Albania.Clinically HFRS is manifested as mild,moderate,or severe.Therefore,the number of cases of Hantavirus' infection may be underestimated,and should be included in the differential diagnosis of many acute infections,hematologic diseases,acute abdominal diseases and renal diseases complicated by acute renal failure.We report... 相似文献

Albumin is one of the most abundant plasma proteins and is heavily glycated in diabetes. In this study, we have addressed whether variation in the albumin levels influence glycation of plasma proteins and HbA1c. The study was performed in three systems: (1) streptozotocin (STZ)-induced diabetic mice plasma, (2) diabetic clinical plasma, and (3) in vitro glycated plasma. Diabetic mice and clinical plasma samples were categorized as diabetic high albumin plasma (DHAP) and diabetic low albumin plasma (DLAP) on the basis of their albumin levels. For the in vitro experiment, two albumin levels, high albumin plasma (HAP) and low albumin plasma (LAP), were created by differential depletion of plasma albumin. Protein glycation was studied by using a combination of two-dimensional electrophoresis (2DE), Western blotting, and LC-MS(E). In both mice and clinical experiments, an increased plasma protein glycation was observed in DLAP than in DHAP. Additionally, plasma albumin levels were negatively correlated with HbA1c. The in vitro experiment with differential depletion of albumin mechanistically showed that the low albumin levels are associated with increased plasma protein glycation and that albumin competes for glycation with other plasma proteins. 相似文献

Down-regulation of c-myc and c-Ha-ras gene expression by tiazofurin in rat hepatoma cells 总被引:3,自引:0,他引:3

There was an overexpression of the c-myc gene (11-fold) and of the c-Ha-ras gene (2-fold) in rat hepatoma 3924A cells compared to normal rat liver as measured by dot-blot analysis of total cytoplasmic RNA. The overexpression of c-myc was attributed to a 10- to 14-fold amplification and rearrangement of the c-myc sequences as determined by Southern blot analysis. The expression of the c-myc also was dependent upon the proliferative state of the hepatoma cells. Tiazofurin (2-beta-D-ribofuranosylthiazole-4-carboxamide; NSC 286193), an inhibitor of the activity of IMP dehydrogenase (EC 1.1.1.205), the rate-limiting enzyme of GTP biosynthesis, resulted in a rapid drop (less than 1 h) to 50% of control in the target enzyme activity in the hepatoma cells and in a subsequent marked decrease to 55% in GTP concentration. These events were followed at 12 h of tiazofurin treatment by a 3-fold reduction in the expression of the c-myc gene and a 9-fold decline in that of the c-Ha-ras gene. These results in the hepatoma cells provide evidence in support of the earlier demonstrated correlation in K562 cells between GTP concentration and expression of c-myc and c-ras genes (Olah et al., 1989). These genes might depend on GTP for their expression in hepatoma cells and they might cooperate in a signal pathway that controls cell proliferation. 相似文献

Analysis of AGE modified proteins and RAGE expression in HER2/neu negative invasive ductal carcinoma
Korwar AM Bhonsle HS Chougale AD Kote SS Gawai KR Ghole VS Koppikar CB Kulkarni MJ 《Biochemical and biophysical research communications》2012,419(3):490-494
Cancer is associated with increased glycolysis and carbonyl stress. In view of this, AGE modified proteins were identified from clinical breast cancer tissue using 2DE-immunoblot and mass-spectrometry. These proteins were identified to be serotransferrin, fibrinogen gamma chain, glycerol-3-phosphate dehydrogenase, lactate dehydrogenase, annexin II, prohibitin and peroxiredoxin 6, which have established role in cancer. Further, RAGE expression and its downstream signaling proteins NADPH oxidase and NF-kB were studied. Role of these AGE modified proteins and RAGE signaling in breast cancer is discussed. 相似文献

We present an efficient computational architecture designed using supervised machine learning model to predict amyloid fibril
forming protein segments, named AmylPepPred. The proposed prediction model is based on bio-physio-chemical properties of
primary sequences and auto-correlation function of their amino acid indices. AmylPepPred provides a user friendly web interface
for the researchers to easily observe the fibril forming and non-fibril forming hexmers in a given protein sequence. We expect that
this stratagem will be highly encouraging in discovering fibril forming regions in proteins thereby benefit in finding therapeutic
agents that specifically aim these sequences for the inhibition and cure of amyloid illnesses.

The treatment of chickpea milk was carried out in batch, repeated batch and continuous reaction by soluble and polyvinyl alcohol (PVA) immobilized Aspergillus oryzae alpha-galactosidase for the removal of raffinose family oligosaccharides (RFOs). In the batch mode of treatment 96 and 92% of RFOs hydrolysis was observed by soluble and immobilized enzyme, respectively. In repeated batch experiments, immobilized enzyme showed 70% RFOs hydrolysis up to sixth cycle. Polyvinyl alcohol immobilized alpha-galactosidase in fluidized bed reactor showed highest reduction of 94% at a flow rate of 30 ml/h. The results obtained from the present study are very interesting for industrial use of PVA-immobilized enzyme. 相似文献
