Evaluation of ornithogalum sigmoideum extract-induced cytotoxicity and expression of xenobiotic metabolism-related genes in HT29 cells.
Article in Molecular biology reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundColorectal cancer (CRC) remains a major cause of cancer-related mortality worldwide, underscoring the need for novel therapeutic strategies. In this preliminary study, the cytotoxic and metabolic effects of Ornithogalum sigmoideum bulb extracts were explored in HT29 colorectal adenocarcinoma cells.
methodsMethanolic extracts were prepared and phytochemically characterized by gas chromatography-mass spectrometry (GC-MS). Cytotoxicity of the extract upon the HT29 cell line, assessed via MTT assay and modulation upon CYP1A1, CYP1B1, and PDX1 at IC₅₀, was examined via Quantitative real-time PCR.
resultsPhytochemical analysis identified methyl hexadecanoate (3.83%), 1,2-Benzenedicarboxylic acid, diethyl ester (3.46%), and methyl octadecanoate (3.18%) as the major constituents within a profile predominantly composed of fatty acid esters, aliphatic hydrocarbons, and aromatic compounds. The MTT assay demonstrated a concentration-dependent reduction in cell viability, with an IC₅₀ value of 429.62 µg/mL, indicating moderate cytotoxic potency. Quantitative real-time PCR analysis showed notable modulation of metabolic gene expression, including moderate downregulation of CYP1A1 and a small-to-moderate upregulation of CYP1B1, while PDX1 expression remained largely unchanged.
conclusionO. sigmoideum extract may modulate the transcription of xenobiotic metabolism-related genes in HT29 cell lines, suggesting a potential effect on metabolic pathways. Further protein-level and functional studies are required to confirm these transcriptional findings.
