Effect and mechanism of curcumin on colon cancer cell senescence through early growth response 1 (EGR1).
Article in Translational cancer research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
Background: The expression level of early growth response 1 (EGR1) is elevated in colon cancer (CC) tissues and is closely associated with poor prognosis in colorectal cancer. However, the role of EGR1 as a transcription factor (TF) influencing cell senescence in the progression of CC remains largely unexplored. This study aims to investigate the impact of curcumin on colorectal cancer cell senescence by modulating EGR1. Methods: Genes associated with cell senescence were obtained from a public database, and ChIP-X predicted TFs were utilized. The R2 database was employed to examine the relationship between gene expression and survival. CC cell lines were transfected with plasmids to achieve stable expression. Stable transfected cell lines were screened, and changes in RNA and protein expression were assessed using real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB) analysis. Senescence levels were measured by SA-β-Gal staining. Cell proliferation and invasion capabilities were evaluated through soft agar and Matrigel invasion assays. Molecular docking was used to predict the interaction between curcumin and EGR1. Gene activity changes were detected using a dual luciferase reporter gene assay. Results: The results indicated that EGR1 was overexpressed in CC tissues and correlated with poor prognosis. As a TF, EGR1 negatively regulated the expression of telomerase reverse transcriptase (TERT) and sirtuin 6 (SIRT6) genes associated with cell senescence. Knocking down EGR1 increased the rate of cell senescence and inhibited cell proliferation and invasion. Curcumin inhibited the transcriptional activity of EGR1, thereby promoting cell senescence and inhibiting tumor progression. Conclusions: In conclusion, curcumin hampers the activity of TF EGR1, affecting the transcription and translation of target genes TERT and SIRT6, thus promoting cell senescence and inhibiting CC cell proliferation. These findings provide potential insights for targeted therapy of CC.
