Mucin-specific lectin from Sambucus sieboldiana (SSA-M) reacts in Western blotting and ELISA with mucins from porcine stomach, bovine and ovine submaxillary glands, the human milk fat globule membrane, in vitro human ovarian, breast and colonic tumor cell lines, and mucins produced in vivo in the
Altered sialyl- and fucosyl-linkage on mucins in cystic fibrosis patients promotes formation of the sialyl-Lewis X determinant on salivary MUC-5B and MUC-7.

Destruction of the lungs as a consequence of recurrent infections with microorganisms such as Pseudomonas aeruginosa remains the underlying cause of most morbidity and mortality in cystic fibrosis (CF). We have hypothesized that changes in the glycosylation of key tracheal mucins such as MUC5B and
Monoclonal antibodies reacting with the mucin-specific lectin from Sambucus sieboldiana (SSA-M).

Monoclonal antibodies (MAbs) were prepared against the mucin-specific lectin from Sambucus sieboldiana (SSA-M). The majority of MAbs reacted with both free SSA-M and SSA-M bound to porcine mucin. However, MAbs SS16, SS18, and SS19 did not react with mucin-bound lectin, suggesting that these MAbs may

Three bark lectins were isolated from elderberry Sambucus sieboldiana using fetuin-Sepharose 4B and mucin-Sepharose 4B, and were studied comparatively for their binding to glycoprotein and to clarify various physicochemical features. For each, a unique pattern on isoelectric focusing was noted and
Reaction of various lectins to mucin derived from the different layers of rat gastric mucosa: comparison of enzyme-linked lectin binding assay with lectin histochemistry.

The purpose of this study was to demonstrate that the histochemical staining reactivities of lectins in rat stomach actually represent the gastric mucins, and to estimate the utility of the lectins for mucin histochemistry. In this paper, the lectin histochemistry was compared with an enzyme-linked
Effects of PGE2 and of different synthetic PGE derivatives on the glycosylation of pig gastric mucins.

The glycosylation of pig gastric mucins, discharged in response to prostaglandin (PG) E2 and to three synthetic PGE-derivatives (misoprostol, nocloprost, rioprostil) was compared. After a 20 h culture period in the absence or presence of 1 micromol/l of one of the PGs, mucins were isolated by gel
POMGNT1 Is Glycosylated by Mucin-Type O-Glycans.

Protein O-linked mannose β1,2-N-acetylglucosaminyltransferase 1 (POMGNT1) is a Golgi glycosyltransferase that catalyzes the formation of the N-acetylglucosamine (GlcNAc) β1→2Man linkage of O-mannosyl glycan. POMGNT1 is not modified by N-glycans because there are no potential N-glycosylation sites;

OBJECTIVE
O-linked carbohydrates (O-glycans) contribute to the hydrophilic character of mucins in mucosal tissues. This study was conducted to identify the repertoire of O-glycans in the tear film and the glycosyltransferases associated with their biosynthesis, in normal subjects and patients with

OBJECTIVE
To determine the expression of membrane-bound mucins and glycan side chain sialic acids in Helicobacter pylori (H. pylori)-associated, non-steroidal inflammatory drug (NSAID)-associated and idiopathic-gastric ulcers.
METHODS
We studied a cohort of randomly selected patients with H. pylori

O-Acetylated sialic acids have been reported in many sialoglycoproteins where they mediate a variety of immune and other biological events. We have previously demonstrated that the protective mucus barrier on the surface of the canine eye contains sialoglycoproteins. We have also investigated the

The glycocalyx of the mucosal surface of urinary bladder acts as an effective barrier against invasion by pathogenic microorganisms and injury from toxic substances in the urine. Defects in these bladder mucosal components could thus be important factors in the development of diseases such as
Novel interactions of complex carbohydrates with peanut (PNA), Ricinus communis (RCA-I), Sambucus nigra (SNA-I) and wheat germ (WGA) agglutinins as revealed by the binding specificities of these lectins towards mucin core-2 O-linked and N-linked glycans and related structures.

Moist mucosal epithelial interfaces that are exposed to external environments are dominated by sugar epitopes, some of which (e.g., sialic acids) are involved in host defense. In this study, we determined the abundance and distribution of two sialic acids to assess differences in their availability
