Tetramethylpyrazine induces reactive oxygen species-based mitochondria-mediated apoptosis in colon cancer cells.

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
backgroundColon cancer is one of the most common malignancies worldwide, and chemotherapy is a widely used strategy in colon cancer clinical therapy. Chemotherapy resistance is the main cause of recurrence and progression in colon cancer. Thus, novel drugs for treatment are urgently needed. Tetramethylpyrazine (TMP), a component of the traditional Chinese medicine Chuanxiong Hort, has been proven to exhibit a beneficial effect in tumors.
aimTo investigate the potential anticancer activity of TMP in colon cancer and the underlying mechanisms.
methodsColon cancer cells were incubated with different concentrations of TMP. Cell viability was evaluated by crystal violet staining assay, and cell apoptosis was assessed by flow cytometry. Apoptosis-associated protein expression was measured using Western blot analysis. Intracellular reactive oxygen species (ROS) levels were assessed by flow cytometry using DCF fluorescence intensity. Xenografts were established by the subcutaneous injection of colon cancer cells into nude mice; tumor growth was monitored and intracellular ROS was detected in tumors by malondialdehyde assay.
resultsTMP induced apoptosis of colon cancer cells
conclusionOur study demonstrates that TMP induces the apoptosis of colon cancer cells and increases the generation of intracellular ROS. TMP triggers mitochondria-mediated apoptosis in a caspase-dependent manner. The accumulation of intracellular ROS is involved in TMP-induced apoptosis. Our findings suggest that TMP may be a potential therapeutic drug for the treatment of colon cancer.
