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

This study investigated the efficacy of quercetin (QCT) in combination with sodium butyrate (NaB) in enhancing apoptosis in rat C6 and human T98G glioblastoma cells though blockage of autophagy under nutrient-starvation. The most synergistic doses of the drugs were determined to be 25 µM QCT and 1 mM NaB in both cell lines. After QCT and QCT + NaB treatments, autophagy quantification with acridine orange staining showed a drastic decrease in protective autophagy in the cells under nutrient-starvation. Decrease in autophagy was correlated with decreases in expression of Beclin-1 and LC3B II. Combination treatment increased the morphological signs of apoptosis including membrane blebbing, nuclear fragmentation, and chromatin condensation. Annexin V staining was also performed for detection and quantification of increases in apoptosis. Western blotting results showed that combination of QCT and NaB increased apoptosis by decreasing anti-apoptotic Bcl-2 and increasing pro-apoptotic Bax, decreasing survivin, activating caspase-3, and degrading poly (ADP-ribose) polymerase (PARP). This study demonstrated the therapeutic potentials of a novel combination therapy in inhibiting protective autophagy to enhance apoptosis in rat C6 and human T98G glioblastoma cells.
