An impedimetric biosensor was developed for the selective detection of the cancer-associated T antigen, using the lectin from Arachis hypogaea (peanut agglutinin, PNA) as the recognition element. The increase in the biosensor's impedance after sample incubation was indicative of lectin recognition
Qualitative changes of glycoconjugates in luminal surface and goblet cell mucin from colon mucosa of 1,2-dimethylhydrazine (DMH)-treated rats were studied. Eight fluoresceinated lectins were used: Dolichos biflorus (DBA), Glycine max (SBA), Triticum vulgare (WGA), Limax flavus (LFA), Arachis
Regional distribution of glycoconjugates in normal and neoplastic colonic mucosa was studied by means of eight lectins: Dolichos biflorus (DBA), Glycine max (SBA), Triticum vulgare (WGA), Arachis hypogaea (PNA), Griffonia simplicifolia-I (GS-I), Canavalia ensiformis (Con A), Limax flavus (LFA), and
A panel of seven fluorescein isothiocyanate (FITC) labeled lectins were used to study the distribution of specific binding sites in histologic sections of rat ovaries and ENU-induced Sertoli cell tumors (SCT) of the ovaries. Ten SCT and 5 normal ovaries derived from Berlin Druckey IV (BD-IV) rats
We examined the staining pattern of various lectins in the malignant and benign prostatic tissues to clarify the difference of sugar residues of mucosubstances between them. The binding of different lectins (Concanavalia ensiformis [Con A], Triticum vulgaris [WAG], Ricinus communis [RCA-I], Arachis
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
Oligosaccharides expressed by the 3327-H and 3327-MAT LyLu sublines of the Dunning rat prostate cancer model have been compared in formalin-fixed and routinely paraffin-embedded tumour tissues. Binding by lectins of defined specificity has been employed to identify expression of seven
Immunocharacterization of intermediate filament proteins and lectin-binding studies were carried out in canine transmissible venereal tumour (TVT), a unique neoplasia sharing some epidemiological features with Kaposi's sarcoma in humans. Neoplastic cells express vimentin, but neither cytokeratin nor
Six granular cell tumors (GCT) of the neurohypophysis were studied by immunohistochemical techniques. They were all labeled by peanut lectin (Arachis hypogaea) and three showed reactivity for S-100 protein. Unlike extracranial GCT, neuron specific enolase (NSE), myelin basic protein (MBP) and
The binding of peroxidase-conjugated Dolichos biflorus (DBA), Triticum vulgaris (WGA), Canavalia ensiformis (Con A), Arachis hypogaea (PNA), Lotus tetragonolobus, and Bandeiraea simplicifolia I (BSAI) to gastrointestinal carcinoid tumours was studied. The results indicate that carcinoid tumour cells
Galectin-3 has been implicated in tumor progression. We demonstrated immunohistochemically that galectin-3 was negative in normal breast tissue, but it was highly increased in breast cancer and in metastatic tissues to brain. Similarly, histochemistry with mucin-specific lectins showed increased
1. Three perchloric acid-soluble fractions from ascites of three primary ovarian cancer patients were subjected to Sephacryl S-300 gel filtration, respectively, and three Fr. 1 which were eluted in the vicinity of void volume as minor fractions, were then separated by a systematic affinity
A rare intracerebral granular cell tumor (GCT) was studied by immunocytochemical and ultrastructural methods. The tumor was composed of two cell types--filament-rich and granular cells. Granular cells contained PAS-positive, diastase-resistant granules that ultrastructurally corresponded to
Lectins linked to fluorescein were used as carbohydrate probes to examine the goblet cell mucin and epithelial cell surface glycoconjugate alterations in an experimental rodent model of colonic neoplasia induced with parenteral 1,2-dimethylhydrazine dihydrochloride. Lectins derived from Triticum
BACKGROUND
We aimed to investigate the tumor biology of nasal IP and identify the biological characteristics associated with early diagnosis and malignant transformation.
METHODS
Lectins immunohistochemistry were performed on inverted papilloma (IP), and associated neoplasms. IP synchronized with
