1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Nanoparticle (NP) exposure has been closely associated with the exacerbation and pathophysiology of many respiratory diseases such as Chronic Obstructive Pulmonary Disease (COPD) and asthma. Mucus hypersecretion and accumulation in the airway are major clinical manifestations commonly found in these diseases. Among a broad spectrum of NPs, titanium dioxide (TiO(2)), one of the PM10 components, is widely utilized in the nanoindustry for manufacturing and processing of various commercial products. Although TiO(2) NPs have been shown to induce cellular nanotoxicity and emphysema-like symptoms, whether TiO(2) NPs can directly induce mucus secretion from airway cells is currently unknown. Herein, we showed that TiO(2) NPs (<75 nm) can directly stimulate mucin secretion from human bronchial ChaGo-K1 epithelial cells via a Ca(2+) signaling mediated pathway. The amount of mucin secreted was quantified with enzyme-linked lectin assay (ELLA). The corresponding changes in cytosolic Ca(2+) concentration were monitored with Rhod-2, a fluorescent Ca(2+) dye. We found that TiO(2) NP-evoked mucin secretion was a function of increasing intracellular Ca(2+) concentration resulting from an extracellular Ca(2+) influx via membrane Ca(2+) channels and cytosolic ER Ca(2+) release. The calcium-induced calcium release (CICR) mechanism played a major role in further amplifying the intracellular Ca(2+) signal and in sustaining a cytosolic Ca(2+) increase. This study provides a potential mechanistic link between airborne NPs and the pathoetiology of pulmonary diseases involving mucus hypersecretion.
