Nicotine inhibits bFGF-induced neurite outgrowth through suppression of NO synthesis in H19-7 cells.

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.
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
NO (Nitric oxide) has been known as a biological signaling molecule that can function as a beneficial agent in physiologically essential functions such as differentiation or neurotransmission. In this study, we elucidated how nicotine inhibits neuronal differentiation induced by the basic fibroblast growth factor (bFGF) in hippocampal cell line, H19-7 cells, because nicotine is one of the key neuroregulatory components. Treatment of H19-7 cells with bFGF increased NO production through upregulated iNOS/ nNOS expression, and also increased expressions of neuronal markers such as brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT3) and Neuro-D. Pretreatment of the cells with nicotine decreased iNOS promoter activity as well as iNOS/nNOS expression induced by bFGF, resulting in decreased NO production. Nicotine also suppressed expressions of BDNF, NT3 and Neuro-D, resulting in decreased bFGF-induced neurite outgrowth. These results indicate that nicotine inhibits bFGF-induced neuronal differentiation in H19-7 cells through inhibition of NO formation by suppressing iNOS/nNOS expressions.
