Of the nine (9) mucin gene transcripts detected, well-characterized antibodies were only available for localization of MUC1, 4, 5AC, 5B, and 6 proteins. both membrane-associated mucins, were detected in most ADX88178 tissues analyzed. Conversely, MUC6 was predominantly detected in seminal vesicle. MUC1, MUC5B and MUC6 were detected in seminal fluid samples by immunoblot analysis. Androgens experienced no effect on mucin expression by cultured human prostatic epithelial cells. CONCLUSIONS Each region of urogenital tract epithelium expressed a unique mucin gene repertoire. Secretory mucins are present in seminal fluid, and androgens do not appear to regulate mucin gene expression. 1995)MUC4528UndilutedPeptideI. K.

Samples lacking main antibody were run as negative controls. Sections were incubated in secondary antibody in ADX88178 the fluorescein-conjugated donkey-anti mouse IgG or donkey-anti chicken IgY (both at 1:50 dilution from Jackson Immuno Research; West Grove, PA) and were coverslipped with Vectashield, a propidium iodide-containing antifade mounting medium that also acts as a nuclear counterstain (Vector Laboratories; Burlingame, CA) (Argueso em et al. /em , 2002). Sections incubated with the MUC6 main antibody, CLH5, were pretreated with neuraminidase as previously reported (Gipson em et al. /em , 1992). Antigen retrieval (15 min at 97C in 10 mM citrate buffer, pH 6. 0) was necessary prior to incubation with the commercially available MUC4 antibody, 1G8. Agarose gel electrophoresis and immunoblot analysis Total protein (125 g) from seminal plasma was denatured and separated under reducing conditions in a 1% (w/v) agarose gel in electrophoresis buffer (Tris/Glycine/SDS), a modification of Thornton et al. (Thornton em et al. /em , 2000). Appropriate controls were ADX88178 also included in the assays to ensure the specificity of the protein detected. The proteins were then vacuum blot transferred to a nitrocellulose membrane, blocked with 5% nonfat dry milk (w/v) in Tris-buffered saline with 0.1% Tween 20 [TTBS] or PBS, and probed with the following antibodies: 214D4 (MUC1), 8G7 (MUC4), CLH2 (MUC5AC), 799W (MUC5AC), and CLH5 (MUC6) (Table II). Following incubation with peroxidase-conjugated-goat-anti-mouse IgG1 (MUC1, 4, 5AC, 6) or anti-chicken IgY (MUC5B) secondary antibody, binding was detected using SuperSignal Western Pico Chemiluminescent Substrate (Pierce; Rockford, IL). Outcomes To be able to determine the mucin profile for local human man urogenital tract epithelia, human being cells from multiple people, as obtainable, were examined for message (discover Desk III) and proteins. Normally, 3 to 7 specimens had been assayed for mucin message and 3 to 9 specimens for mucin proteins, whereas only one one to two 2 specimens of vas deferens and epididymis had been obtainable (discarded epithelial specimens from these cells were difficult to get). Five seminal plasma samples were gathered for immunoblot analysis.

A mucin gene was regarded as indicated by an epithelium if the examples obtained demonstrated a RT-PCR item for your gene. Samples obtained as required lengthy (4 sec) exposures. Mucin proteins and gene manifestation profile Epithelia from all main areas inside the man urogenital tract, from testis to foreskin, had been analyzed for mucin proteins and message. Gene transcripts for MUC1, 3, 4, 5AC, 6, 13, 15, 17, and 20 had been recognized by RT-PCR (Desk III, Shape 1). Human being epithelia recognized to communicate each mucin gene, and their related negative settings, validated all RT-PCR assays C human being trachea (MUC1, 4, 5B, 7, 13, 16, 19, 20), little intestine (MUC2, 3, 17), abdomen (MUC5AC, 6) and salivary gland (MUC15) (data not really demonstrated). The housekeeping gene, GAPDH, was amplified in every of the examples, in support of those examples with quality beginning mRNA had been assayed for mucin gene manifestation. MUC2, 5B, 7,.
