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

Experimental studies were conducted to compare the relative effects of γ-tocotrienol, a natural isoform within the vitamin E family of compounds, with established galectin-3 inhibitor β-lactose, on galectin-3 levels and distribution in highly metastatic human MDA-MB-231, and mouse + SA and TS/A breast cancer cell lines. In contrast to β-lactose, γ-tocotrienol displays a dual-mode binding profile with the carbohydrate recognition domain and hydrophobic pocket located on galectin-3, as determined using Schrödinger molecular modeling. However, treatment with either γ-tocotrienol or β-lactose induces a significant decrease in galectin-3 expression, oligomerization, and a corresponding decrease in fibronectin fibril and lamellipodial protrusion formation, an indication of treatment-induced reversal in epithelial-mesenchymal transition (EMT). These same treatments also caused a significant decrease in galectin-3 Fluorescence Resonance Energy Transfer (FRET) signaling, as compared to the control group, demonstrating the intricate role of galectin-3 in modulating EMT in metastatic breast cancer cells. Combined treatment of doxorubicin with either γ-tocotrienol or β-lactose results in a large increase in doxorubicin levels in the nuclei of metastatic breast cancer cells, the primary site of action for this chemotherapeutic agent. Taken together these findings demonstrate that γ-tocotrienol-induced reversal of EMT in metastatic breast cancer cells is mediated, at least in part, by a disruption in the galectin-3 expression, distribution and function.
