cholesteatoma/tyrosine

The basal stem/progenitor cell maintains homeostasis of the epidermis. Progressive disturbance of this homeostasis has been implicated as a possible cause in the pathogenesis of epithelial disease, such as middle ear cholesteatoma. In many cases of stem/progenitor cell regulation, the importance of

OBJECTIVE Proteomic analysis with 2D electrophoresis and matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) may be a powerful tool for identifying and characterizing the specific proteins relating to the pathogenesis of some diseases, including

OBJECTIVE Detect the expressions of the protein tyrosine phosphatase gene (PTEN), phosphorylated protein kinase B (P-AKT) and phosphorylated extracellular signal-regulated kinase (P-ERK) in human middle ear cholesteatoma tissue and its correlation to explore their important role in the mechanism of

Pseudomonas aeruginosa, a known biofilm-forming organism, is an opportunistic pathogen that plays an important role in chronic otitis media, tracheitis, cholesteatoma, chronic wounds, and implant infections. Eradication of biofilm infections has been a challenge because the biofilm phenotype

OBJECTIVE To explore the cells proliferation and its molecular regulating mechanisms of cholesteatomatous epithelium from the aspect of protein tyrosine kinases (PTKs) signal transduction and cell cycle control. METHODS The expressions of phosphated PTKs, CDK4 and p15 were investigated by
