Latex C-serum from Hevea brasiliensis induces apoptotic cell death in a leukemic cell line.

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
backgroundHevea brasiliensis latex is generally cultivated for the use of rubber particles. Previous studies have shown that the antiproliferative activity of C-serum in hepatocellular carcinoma is not induced through the classical apoptotic signaling pathway. However, in a leukemic cell line, the anti-proliferation effect of latex C serum remained unclear.
methodsLeukemic cell lines (K562 and U937) and human peripheral blood mononuclear cells (PBMCs) were examined for cell viability using the MTT assay. Flow cytometry was used for apoptotic cell detection by annexin V/PI staining. The expression levels of proapoptotic and antiapoptotic marker genes were measured by qRT‒PCR. Moreover, the caspase activities of the extrinsic and intrinsic apoptotic pathways were detected by enzymatic activities.
resultsLatex C-serum inhibited cell proliferation in the K562 and U937 leukemic cell lines but did not affect human PBMCs. Latex C-serum significantly induced the percentage of early and late apoptotic cells in the leukemic cell line. The expression levels of the pro-apoptotic marker genes BAD, BAX, and CASPASE3 significantly increased in the leukemic cell line after post-latex C-serum leukemic cell treatment. The extrinsic, intrinsic and common apoptotic pathways were also studied through caspase-8, -9, and -3 activities. Latex C-serum treatment significantly induced caspase-8, -9, and -3 activation in the K562 cell line and U937 cell line compared to the untreated cells.
conclusionsThese results indicate that latex C-serum enhanced anti-proliferation in leukemic cell lines by inducing apoptosis and caspase activation.
