Normal Cellular Function

Intracellular free Ca2+ ([Ca2+]i) plays a vital role both in maintaining normal cellular function and in cell killing. Few studies have been published regarding its role in ozone (O3)-induced health effects. This study investigated the effect and mechanism of O3 exposure on [Ca2+]i in human tracheal epithelial (HTE) cells. HTE cells grown on Costar Transwell inserts with a liquid-gas interface were exposed to 0, 0.05, 0.1, 0.2 and 0.4 ppm O3 at 37 degrees C for 1 h. After exposure, [Ca2+]i was measured using the fluorescent dye Fluo 3. O3 at 0.4 ppm produced a significant increase in [Ca2+]i, and the increases in [Ca2+]i were blocked by verapamil and 8-(diethylamino)-octyl-3,4,5,-trimethoxybenzoate (TMB-8). These results suggest that the O3-induced [Ca2+]i elevation may involve both Ca2+ release from internal stores and Ca2+ influx across the plasma membrane. Furthermore, both buffer and cell lysate of HTE cells exposed to 0.4 ppm O3 caused a rapid increase in [Ca2+]i of THP-1 human phagocytic monocytes, but the buffer and lysate from air exposed cells did not. These results suggest that O3 exposure causes HTE cells to release a diffusible mediator from the empty Ca(2+)-storing organelle and may be responsible for the sustained and persistent [Ca2+]i elevation in HTE cells exposed to 0.4 ppm O3.

A role for phospholipase C hydrolysis of phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2] as a mechanism of alpha 2-adrenergic signal transduction in rabbit tracheal epithelial cells (tracheocytes) was investigated in isolated cells grown in in vitro culture and prelabeled with myo-[3H]inositol (3 microCi/ml) for 72 h. Breakdown of polyphosphoinositides was measured by using thin-layer chromatography to detect phosphatidylinositol, phosphatidylinositol 4-phosphate [PtdIns(4)P], and PtdIns(4,5)P2. Inositol phosphates were separated by ion-exchange column chromatography. The endogenous catecholamine l-epinephrine and alpha 2-adrenergic agonists clonidine and 1-(2,6-dichlorobenzylideneamino)guanidine (guanabenz) produced a rapid transient accumulation of inositol trisphosphate and inositol 4,5-bisphosphate and breakdown of [PtdIns(4)P] and PtdIns(4,5)P2. The alpha 2-adrenergic effects were not blocked by the beta-adrenergic antagonist DL-propranolol or by the alpha 1-adrenergic antagonists prazosin and methylurapidil but were inhibited by pertussis toxin and blocked by yohimbine, an alpha 2-adrenergic antagonist. The 50% effective concentration for guanabenz-stimulated inositol trisphosphate generation was right shifted from 0.3 to 0.9 microM by yohimbine. The results provide the first demonstration of alpha 2A-adrenergic activation of pertussis toxin-sensitive PtdIns(4,5)P2-dependent phospholipase C in mammalian tracheocytes. The findings are consistent with previous observations on alpha 2A-adrenergic-mediated activation of NaCl cotransport in these cells.
