leukoplakia/carbohydrate

Cell surface carbohydrates in healthy oral mucosa (n = 15), leukoplakias without (n = 48) and with (n = 62) dysplasia, oral papillomas (n = 6) and squamous cell carcinomas (SCCs) (n = 40) were examined using the lectins peanut agglutinin (PNA), Ulex europaeus agglutinin I (UEA I), soybean agglutinin

The keratohyalin granules from 25 human oral leukoplakias, showing benign hyperorthokeratosis histologically, were examined employing a series of histochemical techniques. The tissues were fixed in 10% neutral buffered formalin, 80% methanol, or Carnoy's fluid. The keratohyalin granules stained

The distribution of carbohydrate structures related to the ABO(H) blood group antigen system was studied in biopsies from eight squamous cell carcinomas, and eight erythroplakias with epithelial dysplasia. Twenty oral lesions without histological evidence of malignancy (13 lichen planus lesions and

Ulex europeus (Ulex 1) has been used to study the expression of cell surface alpha-L-fucose on oral epithelial cells of normal human mucosa, white lesions and carcinomas. In normal tissue and in 11 of 12 specimens of non-specific keratoses (leukoplakia), Ulex 1 stained epithelial spinous cells only.

Galectin-1 (Gal-1) is a newly found immunoregulatory carbohydrate-binding protein in cancer biology. The purpose of this study was to evaluate the effects of Gal-1 on oral squamous cell carcinoma (OSCC) development. Immunohistochemistry, Western blotting and RT-PCR were carried out in 62 primary
