Human beta-defensin-1: an antimicrobial peptide of urogenital tissues.
Antimicrobial peptides are widely distributed mediators of innate host defense in animals and plants. A 36 amino acid antimicrobial peptide belonging to the defensin family, and named human beta-defensin-1 (HBD-1), was purified recently from hemodialysate fluid, but its tissue sources were not identified. By Northern blotting, we found the highest concentrations of HBD-1 mRNA in the kidney and ...
متن کاملCimetidine induces apoptosis of human salivary gland tumor cells.
It has been reported that cimetidine, a histamine type-2 receptor (H2R) antagonist, inhibits the growth of glandular tumors such as colorectal cancer. However, its effects against salivary gland tumors are still unknown. We demonstrated previously that human salivary gland tumor (HSG) cells spontaneously express the neural cell adhesion molecule (NCAM) and also that HSG cell proliferation could...
متن کاملIn vitro activity of human beta-defensin 2 against Pseudomonas aeruginosa in the presence of tear fluid.
Pseudomonas aeruginosa causes vision-threatening keratitis and is difficult to treat due to emerging resistance. Human beta-defensin 2 (hBD-2) is an antimicrobial peptide expressed by ocular surface epithelia with broad-spectrum activity against various pathogens, including P. aeruginosa. The activity of hBD-2 against P. aeruginosa in the presence of human tears or NaCl was studied. In some exp...
متن کاملConsistent absence of BRAF mutations in salivary gland carcinomas
Introduction: Malignant salivary gland tumors are rare entities. Despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. The activation of EGFR- RAS-RAF signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic m...
متن کاملA Review of Signet Ring cells in Salivary Gland Tumors
Objectives: Signet Ring Cells (SRCs) are often seen in gastrointestinal, breast, bile duct and lung invasive carcinomas. Observing these cells in benign and malignant lesions of the salivary glands is not common. Signet-ring cell adenocarcinoma is rare and is commonly seen in the secondary salivary glands. Although, the presence of SRCs in other neoplasms of the body is usually associated with ...
