fibrocystic breast disease/protease

The precise origin of breast cyst fluid remains obscure. Molina has presented evidence that type II cysts (high Na/K ratio) may be transudative, that is, partly derived from plasma elements which enter through gap junctions, while Type I cysts (high K/Na ratio) are primarily secretory. In

Cyst fluid from women with gross cystic breast disease was found to contain protease activity when assayed against [14C]albumin. At least six different proteases were detected when the fluid was fractionated by a combination of S-300 Sephacel, hydroxylapatite, and DEAE-Sephacel chromatographic

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

The necessity of screening high-risk patients with breast cancer who may require more intensive systemic therapy especially in the node negative subgroup was generally accepted. Cathepsin D, an estrogen induced protease, has been shown to be implicated in the proliferation and invasion of breast

We demonstrate for the first time that prostate specific antigen (PSA) is a component of breast cyst fluid. At the cutoff level of 0.01 or 0.03 micrograms/L of PSA, 64% or 43% of cyst fluids are positive for PSA, respectively. PSA in cyst fluid, as characterized by high performance liquid

BACKGROUND Human glandular kallikrein (hK2) belongs to the serine protease family of enzymes and has high sequence homology with prostate-specific antigen (PSA). The physiological role of hK2 has not as yet been determined, but there is evidence that it can regulate the proteolytic activity of PSA

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

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

Inflammation remains a key event during most of the diseases and physiological imbalance. Acute inflammation is an essential physiological event by immune system for a protective measure to remove cause of inflammation and failure of resolution lead to chronic inflammation. Over a period of time, a
