Alpha7 nicotinic acetylcholine receptor expression in Sorafenib-resistant Hepatocellular carcinoma cells.
Article in Medical oncology (Northwood, London, England), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Hepatocellular carcinoma (HCC), the most prevalent kind of liver cancer, remains one of the world's main causes of death. The alpha7 nicotinic acetylcholine receptor (α7nAchR) has been recognized to be overexpressed in malignancies and chemoresistance. Since little is known about the role of α7nAchR expression in drug-resistant cells, this study was designed to investigate the effect of α7nAchR suppression in combination with Sorafenib (SOR) on SOR-resistant HCC cells. First, SOR-resistant HCC cells were generated. To suppress the expression of α7nAchR, cells were treated with SOR following siRNA transfection. qRT-PCR was used to examine the expression of α7nAchR and apoptotic genes by evaluating the IC50 of SOR and the combination of α7nAchR siRNA and SOR on the survival of resistant cells. Moreover, apoptosis, autophagy, and cell cycle analysis for resistant HCC cells were performed using flow cytometry. Cell migration and colony formation assays were also used for further confirmation. Our results suggest that inhibiting α7nAchR can lead resistant HCC cells to become sensitive. Furthermore, when siRNA and SOR were treated together, HCC-resistant cells showed a considerable reduction in α7nAchR mRNA gene expression. In addition, when α7nAchR was downregulated in combination with SOR, migration and colony formation were inhibited. Apoptosis was triggered by modulating the expression of apoptotic target genes, and cell cycle arrest was observed in the G2-M and subG1 phases. Overexpression of α7nAchR in SOR-resistant HCC cells suggests that it might be a therapeutic target for HCC cell resistance therapy.
