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

Leonurus sibiricus L. is a traditional medicinal plant which occurs in southern Siberia, China, Korea, Japan, and Vietnam. The plant shows several pharmacological effects, but the most interesting is its anti-cancer activity. The aim of our study was to examine the induction of apoptosis in malignant glioma cells, the most aggressive primary brain tumors of the central nervous system, following treatment with transformed root (TR) or non-transformed root (NR) L. sibiricus extracts. Both the NR and TR extracts were found to have cytotoxic activity in the glioma primary cells. The human glioblastoma cell lines obtained from patients were confirmed to be tumorogenic by the following three markers: D10S1709, D10S1172, and D22S283. HPLC and MS analysis revealed the presence of polyphenolic compounds (chlorogenic acid, ferulic acid, caffeic acid, p-coumaric acid, ellagic acid, and verbascoside) in both sets of root extracts. In summary, our findings demonstrate that treatment of the glioma cells with NR and TR extracts resulted (a) in significant cell growth inhibition, (b) S- and G2/M-phase cell cycle arrest, and (c) apoptosis in a dose-dependent fashion by changing Bax/Bcl-2 ratio (about 4-fold increase) and p53 (5-fold increase) activation. These findings indicate that NR and TR extracts exhibit anti-cancer activity through the regulation of genes involved in apoptosis. This is the first report to demonstrate the cytotoxic effect of polyphenolic extracts from L. sibiricus roots against glioma cells, but further studies are required to understand the complete mechanism of its apoptosic activity.
