bladder/protease

The role of protease-activated receptor-2 (PAR-2) in the regulation of the rat urinary bladder contractility was investigated. Both trypsin and PAR-2 activating peptide (SLIGRL-NH(2)) produced a concentration-dependent contractile response in the urinary bladder preparations. These contractions were

The acid-soluble extract of the bladder mucosal surface was obtained by washing out the bladder with dilute acetic acid in the presence of protease inhibitors. The wash-out materials from rats, rabbits, pigs, and humans manifested strong bactericidal activity against E. coli in vitro. The

There is a growing body of basic science and epidemiologic evidence to support a research thrust to determine whether several natural or synthetic agents, given alone or together, can lower cancer incidence. Candidate agents include analogs of vitamin A and the vitamin A precursor, beta-carotene,

OBJECTIVE Studies suggest that protease activated receptors (PARs) are mediators of inflammation and repair. Studies suggest a neurogenic mechanism for PAR2 in inflammation and the fact that interaction between PAR2 and transient receptor vanilloid receptor (TRPV1 or VR1) are important for the

BACKGROUND Bladder pain is a prominent symptom in several urological conditions (e.g. infection, painful bladder syndrome/interstitial cystitis, cancer). Understanding the mechanism of bladder pain is important, particularly when the pain is not accompanied by bladder pathology. Stimulation of

The cysteine proteases of Paragonimus westermani metacercariae are involved in metacercarial excystment, host immune modulation, and possibly in tissue penetration. In order to clarify the origin of the enzymes, 28 and 27 kDa cysteine proteases in metacercarial excretory-secretory products were

Bladder pain is a prominent symptom of interstitial cystitis/painful bladder syndrome. Hydrogen sulfide (H2S) generated by cystathionine β-synthase (CBS) or cystathionine γ-lyase (CSE) facilitates bladder hypersensitivity. We assessed involvement of the H2S pathway in protease-activated receptor 4

Cathepsin D was measured in cytosols of 60 malignant bladder specimens and normal tissue from the same bladder at safety margin 5 cm of the tumor. Significant elevation in cathepsin D level (50 +/- 3.5 pmol/mg protein) in bladder carcinoma compared to normal tissue (12.7 +/- 1.58 pmol/mg protein)

The cysteine proteases of Paragonimus westermani metacercaria are known to initiate metacercaria excystment. However, their secretory sites, such as the intestine, tegument, and excretory bladder are not well defined. In this study, the metacercariae were labeled with bromodeoxyuridine (BrdU) to

Pain is the significant presenting symptom in Interstitial Cystitis/Painful Bladder Syndrome (IC/PBS). Activation of urothelial protease activated receptor 4 (PAR4) causes pain through release of urothelial macrophage migration inhibitory factor (MIF). High Mobility Group Box-1 (HMGB1), a

BACKGROUND All four PARs are present in the urinary bladder, and their expression is altered during inflammation. In order to search for therapeutic targets other than the receptors themselves, we set forth to determine TFs downstream of PAR activation in the C57BL/6 urinary bladders. METHODS For

BACKGROUND Macrophage migration inhibitory factor (MIF), a pro-inflammatory cytokine, is constitutively expressed in urothelial cells that also express protease-activated receptors (PAR). Urothelial PAR1 receptors were shown to mediate bladder inflammation. We showed that PAR1 and PAR4 activator,

OBJECTIVE The emptying of the gall bladder in response to feeding is pivotal for the digestion of fat, but the role of various food ingredients in contracting the gall bladder postprandially is not well understood. We hypothesized that different food ingredients, when consumed, will have a different

Increased mast cell numbers and mast cell activation represent one of the prevalent etiologic theories for interstitial cystitis, an inflammatory condition in the bladder. This study was designed primarily to determine whether increased mast cell tryptase in the bladder wall may play a role in
