Effects of folic acid deficiency on genetic damage in colorectal cancer cells.
Article in American journal of translational research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo explore the effect of folic acid deficiency on genetic damage and mRNA expression in colorectal cancer cells.
methodsWe cultured human colonic epithelial cells ccd-841-con and colonic adenocarcinoma cells Caco-2 with RPMI1640 medium in folic acid-deficient concentration (22.6 nM) and standard concentration (2260 nM), respectively. Cytokinesis-block micronucleus cytometer was used to evaluate and compare the genetic damage of the tested cells. Poly(a) tailing method and dual luciferase reporter gene detection system were used to analyze the expression of miR-200a and its relationship with miR-190. Furthermore, the miR-190 expression was measured by RT-qPCR.
resultsWhen folic acid was deficient for 21 days, the frequency of genetic damage was increased in both types of tested cells, and micronucleus, a marker associated with chromosome breakage, was dominant (P < 0.01). miR-200a targeted the 3'-UTR region of miR-190. In colonic epithelial cells ccd-841-con, the transcript levels of miR-200a and miR-190 were upregulated when folic acid was depleted for 21 days (P < 0.01).
conclusionsFolate deficiency can cause cytogenetic damage and affect the expression of miR-200a and miR-190 in rectal cancer cells.
