Genome-Wide Impact of Folic Acid on DNA Methylation and Gene Expression in Lupus Adipocytes: An In Vitro Study on Obesity.

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
objectiveThis in vitro study aimed to investigate the impact of folic acid on DNA methylation and gene expression in adipocytes from subcutaneous adipose tissue of patients with systemic lupus erythematosus (SLE), with a focus on the influence of obesity on these epigenetic changes.
methodsTissue biopsies were collected from patients with normal weight (NW) and obesity (OBS). Adipocytes were isolated via enzymatic digestion and density separation. Each group was divided into control (standard medium) and folic acid treatment (2 mg/24 h for 48 h) conditions. After treatment, DNA methylation levels were analyzed using the Infinium Methylation EPIC v2.0 Kit, and gene expression analyses were performed by RT-qPCR. A pathway enrichment analysis was conducted using the KEGG database for functional insight.
resultsFolic acid induced differential methylation at 755 CpG sites in NW adipocytes, which were associated with immune regulation, including MAPK signaling. Also, OBS adipocytes showed methylation changes at 92 CpG sites, affecting pathways related to metabolic regulation, such as cAMP signaling.
conclusionsFolic acid treatment exerts distinct epigenetic and gene expression effects in adipocytes of SLE patients, modulated by obesity status. This weight-dependent response, marked by changes in pathways relevant to immune and metabolic function, highlights the need for further investigation into how nutrient-based interventions might support SLE management. From a clinical perspective, this study underscores the potential of targeted nutrient-based interventions to address immunometabolic dysfunctions in SLE patients. Further research could explore folic acid supplementation as a complementary approach to personalized treatment strategies, particularly for patients with obesity.
