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

objectiveTo investigate the effect of curcumin on viability of clear cell renal cell carcinoma (ccRCC) and analyze its possible mechanism.

methodsIn cell lines of A498 and 786-O, the effects of curcumin (1.25, 2.5, 5 and 10 μ mol/L) on the viability of ccRCC were analyzed at 24, 48 and 72 h by MTT assay. The protein expression levels of ADAMTS18 gene, p65, phosphorylation p65 (pp65), AKT, phosphorylation AKT (pAKT) and matrix metallopeptidase 2 (MMP-2) before and after curcumin (10 μ mol/L) treatment were examined by Western blotting. Real-time PCR and methylation specific PCR (MSP) were applied to analyze the expression and methylation level of ADAMTS18 gene before and after curcumin treatment (10 μ mol/L).

resultsCurcumin significantly inhibited the viability of A498 and 786-O cell lines in a dose- and time-dependent manner (P<0.01). Up-regulation of ADAMTS18 gene expression with down-regulation of ADAMTS18 gene methylation was reflected after curcumin treatment, accompanied by down-regulation of nuclear factor κ B (NF-κ kB) related protein (p65 and pp65), AKT related protein (AKT and pAKT), and NF-κ B/AKT common related protein MMP-2. With ADAMTS18 gene overexpressed, the expression levels of p65, AKT and MMP2 were downregulated, of which were conversely up-regulated in silenced ADAMTS18 (sh-ADAMTS18). The expression of pp65, pAKT and MMP2 in sh-ADAMTS18 was down-regulated after being treated with PDTC (NF-κ B inhibitor) and LY294002 (AKT inhibitor).

conclusionsCurcumin could inhibit the viability of ccRCC by down-regulating ADAMTS18 gene methylation though NF-κ B and AKT signaling pathway.
