Construction and identification of the pshRNA-CACNA1G-SH-SY5Ycells targeted to silence Cav3.1 mRNA expression.
Article in Biomedical reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
T-type calcium channels are a class of low voltage-dependent calcium channels that may be activated following minor depolarizations of the cell membrane. Cav3.1 is the dominant subtype of the T-type calcium channel in SH-SY5Y cells. T-type channels play a key role in the regulation of the intracellular calcium concentration, which is involved in the neurotoxic effect of local anesthetics. However, there is a lack of specific inhibitors of T-type calcium channels. The existing T-type calcium channel inhibitors exhibit poor specificity and may block the high voltage-dependent calcium channels, such as the L- and N-type channels. Furthermore, there is no selectivity to the subtype of the T-type calcium channel. Therefore, the development of a specific T-type calcium channel inhibitor may contribute to the elucidation of the functions and characteristics of T-type calcium channels. The aim of this study was to silence the Cav3.1 mRNA expression in SH-SY5Y cells via the RNA interference (RNAi) method in order to construct pshRNA-CACNA1G-SH-SY5Y cells and assess Cav3.1 mRNA and protein expression by western blot analysis and reverse transcription-polymerase chain reaction (RT-PCR) to identify the constructed cell line. The results demonstrated that Cav3.1 mRNA and protein expression were significantly reduced following transfection with the SH-SY5Y cells by the supernatant liquors. The results also demonstrated that the pshRNA-CACNA1G-SH-SY5Y cells were successfully constructed. These findings may contribute to the elucidation of the functions of Cav3.1 in SH-SY5Y cells.
