The caspase pathway of linoelaidic acid (9t, 12t-c18:2)-induced apoptosis in human umbilical vein endothelial 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
Trans fatty acids (TFA) are reported to contribute to inflammation and coronary heart disease. The study aim was to investigate the proapoptotic effects of two double bond TFA (TDTFA) on human umbilical vein endothelial cells (HUVEC). The HUVEC were grown in media supplied with linoelaidic acid (9t,12t-C18:2) at 50, 100, 200, 400 μmol/l for 24 or 48 h to examine the effects of TDTFA on the viability and apoptosis of these cells. Flow cytometry analysis and confocal scanning were used to measure apoptosis, cell binding of Annexin V and propidium iodide uptake. Colorimetric assay and RT-PCR were used to analyze enzyme activities and mRNA expression of caspase-3, -8 and -9 in HUVEC. Results showed that 9t,12t-C18:2 inhibited the viability of HUVEC in a dose-dependent and time-dependent manner. The percentages of 9t,12t-C18:2 induced apoptotic and necrotic cells significantly increased compared with that of the control. The activities and mRNA expression of caspase-8, -9 and -3 were significantly increased in 9t,12t-C18:2 treated cells compared to that of the control. Addition of specific inhibitors of caspase-8 (z-IETD-fmk) and caspase-9 (z-LEHD-fmk) to HUVEC was found to completely inhibit 9t,12t-C18:2-induced activation of caspase-3, and z-IETD-fmk inhibited the activation of caspase-9. Meanwhile, it was found that mRNA expression of Bid, Smac/DIABLO and the release of mitochondrial cytochrome c were significantly elevated by 9t,12t-C18:2 treatment. These results suggest that 9t,12t-C18:2 may induce apoptosis of HUVEC through activating caspase-8, -9 and -3. Both the death receptor pathway and the mitochondrial pathway may be involved in the apoptosis induced by 9t,12t-C18:2.
