OBJECTIVES To investigate the expression of prostaglandin E2 receptor subtypes, E-prostanoid (EP) 1-4 receptors, in acquired cholesteatoma and its possible role in the pathologic process of this disorder. METHODS Specimens of human acquired cholesteatoma were obtained from 29 patients and 19 skin biopsies of normal external auditory canal were as controls. The mRNA and protein expression of E...
متن کاملTNF-R2 expression in acquired middle ear cholesteatoma.
UNLABELLED Acquired middle ear cholesteatoma is a disease which promotes bone erosion resulting in potentially serious complications. The tumor necrosis factor alpha (TNF-α) is present in cholesteatoma and it is related to bone erosion, as shown by different authors. To understand the aggressiveness characteristics of cholesteatoma is necessary, however, to better address the presence and distr...
