Bikunin, which is an inhibitor of serine proteases, is widely distributed in human tissues, including liver, kidney, and mucous membranes of the stomach and colon. The aim of this study was to clarify whether bikunin is expressed in human epidermis and its appendages. Immunoblot analysis using a
GCDFP-15 (gross cystic disease fluid protein, 15 kDa) is a secretory marker of apocrine differentiation in breast carcinoma. In human breast cancer cell lines, gene expression is regulated by hormones, including androgens and prolactin. The protein is also known under different names in different
Prostate-specific antigen (PSA), a serine protease thought to be exclusively produced by the prostate epithelial cells, has been recently found in human breast tissues and fluids. PSA in breast cancer is associated with the presence of steroid-hormones and receptors, and its presence seems to be a
Prolactin-induced protein (PIP) is a 17-kDa single polypeptide chain that is secreted by a number of normal apocrine cells, such as milk, saliva, and seminal fluid. PIP is widely expressed in breast cancer and is commonly used as a diagnostic biomarker for the histopathological diagnosis of this
Cytoplasmic clarity is a histological feature of normal prostatic secretory cells, but in this study, tissue fixation in strong (>2.5%) glutaraldehyde dramatically altered cytological staining. Secretory cytoplasm appeared red and granular on routine stains because of myriad intensely staining
Monoclonal antibody 7B10, raised against the human breast cancer cell line T47D, identifies an antigen found in human breast carcinomas and in normal breast. Western blot and immunoprecipitation studies detected a Mr 76,000 antigen in cytosol, cell membrane, and cell culture supernatants of T47D
The frequency of gross cystic breast disease in premenopausal women and its possible association with increased breast cancer risk emphasises the importance of investigations relating to breast cyst fluid composition. In order to contribute to a better analysis of this medium, we have measured the
Acne inversa (AI, OMIM 142690), also called hidradenitis suppurativa, is a chronic, inflammatory, recurrent and debilitating skin follicular disease that usually presents after puberty with painful, deep-seated, inflamed lesions in the apocrine gland-bearing areas of the body, most commonly the
Gross cystic breast disease (GCBD) is the most common benign disease of the human female breast, and patients with GCBD have an increased risk of breast cancer. The aim of this study was to evaluate the distribution inside apocrine cells and in breast cyst fluids aspirated from gross cysts of
Alpha 1-antichymotrypsin, a serum protease inhibitor, was found in 72 breast cyst fluids aspirated from women affected by gross cystic breast disease. When fractionated by gel chromatography, the presence of protein complexes or aggregates was demonstrated. A different distribution of the alpha
There are two types of breast cyst and women with apocrine breast cyst may have a higher risk of developing breast cancer than cyst lined by flattened epithelium. Transforming growth factor-beta's growth inhibitory effect on epithelial cells suggests a potential protective role in breast cancer. The
Recent findings in familial hidradenitis suppurativa (HS) demonstrated loss-of-function mutations of components of the γ-secretase (GS) complex leading to decreased protease cleaving activity, which may compromise canonical Notch signalling. Appropriate Notch signalling is of pivotal importance for
