Lectins are proteins and glycoproteins of non-immune origin which bind specifically to carbohydrate residues, agglutinate cells and/or precipitate complex carbohydrates. Lectin-binding patterns in normal, hyperplastic and neoplastic endometria were studied using four biotinylated lectins (Con A,
This investigation of diet and other environmental factors reports on 588 patients with colorectal cancer and 1,176 hospitalized controls in three prefectures of Japan. Weak (not statistically significant) positive effects were found for social class and urbanization. The significant association of
OBJECTIVE
Endocervical and endometrial tissues were stained with four lectins to determine the difference in staining pattern between non-neoplastic and neoplastic conditions of these tissues.
RESULTS
The lectins used were Ulex europaeus agglutinin (UEA), Dolicho biflorus agglutinin (DBA).
A 64-kDa hemagglutinin from a Phaseolus vulgaris cultivar, the northeast red bean, was purified by a protocol composed of three chromatographic steps involving affinity chromatography on Affi-gel blue gel, cation exchange chromatography on SP-Sepharose and FPLC-gel filtration on Superdex 75. The
Beans (Phaseolus vulgaris) are an important food staple in many traditional diets. There is limited evidence to suggest an inverse relationship between bean consumption and colon cancer. The objective of this study was to determine whether consumption of black beans and/or navy beans would reduce
A proteolytic activity associated with the microsomal fraction of L-5178Y/Esb tumor cells has been characterized. The enzyme has a molecular weight of 80-90 kD as determined by affinity-labelling with [3H]DFP and SDS-gel electrophoresis. It cleaves ester substrates at the carboxyl position of lysine
Affinity electrophoresis of human alpha-fetoprotein (AFP) with the erythroagglutinating phytohemagglutinin of Phaseolus vulgaris (E-PHA) gave up to five resolved bands (y, h, i, l and a; given in the order of decreasing affinity for E-PHA); band a having no affinity and bands y and h representing
Common beans ( Phaseolus vulgaris L.) contain a high proportion of undigested carbohydrates (NDC) that can be fermented in the large intestine to produce short-chain fatty acids (SCFA) such as acetate, propionate, and butyrate. The objective of the present study was to evaluate the composition and
We have examined the ability of 5 tumour cell types to attach to plastic flasks in medium containing either 10% foetal calf serum or 10% normal human serum and compared this ability with cell-associated caseinolytic activity. The cell types used included fibrosarcoma cells which were obtained from a
To search for dried plant seeds with potent anti-diabetes activity, we conducted a large scale screening for inhibitory activity on tumor necrosis factor-alpha and facilitating activity on adiponectin production in vitro. These activities in 3T3-L1 adipocytes were screened from ethanol extracts of
BACKGROUND
Alteration of the expression of glycoconjugates is frequently observed in tumors. However, studies on the changes of cellular glycosylation in the early premalignant stage of prostate carcinogenesis are scarce.
METHODS
The present study characterized and compared the glycoconjugates
Blood-group-related antigens expressed in papillary carcinomas and other types of neoplasm of the human thyroid glands have been shown to be carried by poly-N-acetyllactosamines containing a linear domain susceptible to endo-beta-galactosidase digestion. To make clear more precisely the backbone
Morphologic and histochemical characteristics were noted for three spontaneous tumors with eosinophilic cytoplasmic granules that occurred in aged Fischer 344 rats. Macroscopic lesions were widely distributed in the body, mainly involving the intra-abdominal adipose tissue, pancreas, and
Legumes are considered to be a very good source of polyphenolic compounds that may act as chemopreventive agents, especially by their antioxidant properties. However, many of the chemopreventive properties may depend on the concentrations of the phytochemical compounds because potent antioxidant
A scanning electron microscopic study of indole-3-acetic acid (IAA) induced tumour in the hypocotyl region of bean embryos shows a distinct morphological, structural and topographical change from the non-treated bean embryos. The IAA-induced tumour surface, in the hypocotyl region, shows distinct
