The purification and serological and chemical properties of Vicia graminea lectin (VGA) and Vicia unijuga lectin (VUA) were described, and then the binding-specificity of anti-M and -N antibodies and both the lectins was discussed in this review. On the basis of the facts that Vgu glycoproteins
We investigated biosynthesis of Vicia graminea lectin (VGA)- and Vicia unijuga lectin (VUA)-binding (Vgu) glycoproteins, which are human malignant tumor-associated antigens, in cultured human tumor and non-tumor cells by pulse-labeling experiments with [35S]-methionine, followed by
Chemical investigation of Vicia monantha subsp. monantha Retz. revealed isolation of one new hydroxy- fatty acid (6) identified as (6-Z, 10-E)-9-hydroxy henicosa-6,10-dienoic acid in addition to six known metabolites; hexadecanoic acid (1), β-sitosterol (2), β-amyrin (3), β-sitosterol-glucoside (4),
We have previously reported that Vicia graminea lectin (VGA)- and Vicia unijuga lectin (VUA)-binding glycoproteins (Vgu glycoproteins), malignant tumor-associated antigens, exist in human meconium and amniotic fluid. To examine the origin of Vgu glycoprotein, their presence, some of their chemical
Vgu glycoprotein (Vicia graminea lectin- or Vicia unijuga lectin-binding glycoprotein) has been reported as oncofetal antigen, which is found in many kind of tumor tissues, amniotic fluid and fetal membranes. In autoradiography with an 125I-labeled Vicia unijuga lectin (VUA) probe and an
Perchloric acid-soluble fractions (PASFs) were obtained from cyst fluids of human benign ovarian mucinous cystadenoma, benign dermoid cyst, "borderline" mucinous cystadenoma, and malignant ovarian clear cell carcinoma, and from fluids of malignant embryonal carcinoma and malignant serous
Vicia graminea- and Vicia unijuga-binding glycoprotein (Vgu glycoprotein) has been reported as a malignant tumor-associated antigen, which is found in various kinds of malignant tumor-tissues and ascitic and cyst fluids of malignant tumor patients, but not found in 20 kinds of normal human tissues.
A lectin present in the broad bean, Vicia faba, was isolated by affinity chromatography on Sephadex G-150. The active lectin had a molecular weight of 50 000. The lectin contained about 3% neutral sugar and it contained two different subunits. The subunits had molecular weights of 17 300 and 14 300.
BACKGROUND
Dietary lectins can alter the proliferation of colonic cells. Differentiation is regulated by adhesion molecules which, being glycosylated, are targets for lectin binding.
OBJECTIVE
To examine the effects of dietary lectins on differentiation, adhesion, and proliferation of colorectal
A single dose of 10 mg of 7,12-dimethylbenz[a]anthracene (DMBA), administered to rats through intragastric intubation, was sufficient to induce many biochemical and histopathological changes in their mammary tissue. Significant increases were observed in the activity levels of the enzymes acid
Vicia sativa L. (common vetch) is a potential food source for both human beings and animals because of its abundant nutritional composition. There is a lack of phytochemical study on the whole plant, and thus the objective of this study was to investigate the isolation of phytochemicals and evaluate
Recently, several investigators have demonstrated that the MN blood group precursor antigens Thomsen-Friedenreich antigen (T-Ag) and Tn-antigen (Tn-Ag) are expressed on the cell surfaces of several cancers, including urinary bladder cancer. T-Ag is composed of a specific carbohydrate chain,
Cathepsin D is a lysosomal protease which plays an important role in cancer invasion and metastasis. There are known inhibitors of that enzyme, such as pepstatin and potato inhibitor. In this study, we examined effects of the cathepsin D inhibitor from Vicia sativa L. seed hulls on cell cultures of
Exposure to inorganic arsenic (iAs) through drinking water is a major public health concern affecting most countries. Epidemiologic studies showed a significant association between consumption of iAs through drinking water and different types of cancer. However, the exact mechanisms underlying
