Early thyroid hormone-induced gene expression changes in N2a-β neuroblastoma 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
Thyroid hormone has long been known to regulate neural development. Hypothyroidism during pregnancy and early postnatal period has severe neurological consequences including even mental retardation. The purpose of this study was to characterize gene expression pattern during thyroid hormone-induced differentiation of neuro-2a β cells in order to select "direct response genes" for further analysis. In this neuroblastoma cell line, thyroid hormone blocks proliferation and induces differentiation. Changes in gene expression level were examined after a T3 treatment of 3 and 24 h using cDNA arrays. Sixteen genes were significantly up-regulated and 79 down-regulated by T3 treatment. Five up-regulated genes not previously described as regulated by thyroid hormone and selected for their putative significance to understand T3 action on cell differentiation, were verified by RT-PCR analysis. The transcription factors Phox2a and basic helix-loop-helix domain containing, class B2 mRNAs exhibited a clear increase after 3- and 24-h treatment. The guanine-nucleotide exchange factor RalGDS was greatly up-regulated after 3-h treatment but not 24 h after. The results suggest an early involvement of these genes in T3 action during neuroblastoma cell differentiation probably mediating later changes in gene expression pattern.
