Altered Methylation Levels in LINE-1 in Dental Pulp Stem Cell-Derived Osteoblasts.
Article in International dental journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectivesLong interspersed nuclear element-1 (LINE-1) and Alu elements are major targets of methylation, an epigenetic mechanism that is associated with several biological processes. Alterations of methylation of LINE-1 and Alu have been reported in cancers, diseases, and ageing. However, these alterations have not been studied in osteogenic differentiation of dental pulp stem cells (DPSCs), which are a promising source of tissue regeneration.
methodThis study was performed to investigate the methylation level of LINE-1 and Alu in dental pulp stem cell-derived osteoblasts (DPSC-DOs). By using the combined bisulfite restriction analysis, the levels of total methylation and 4 patterns of methylated cytosine-phosphate-guanine (CpG) dinucleotides of LINE-1 and Alu were compared between DPSC-DOs and DPSCs.
resultThe levels of total methylation and hypermethylated CpG dinucleotides of LINE-1 were significantly lower (P = .015 and .021, respectively), whilst levels of one pattern of partial methylated CpG dinucleotides were significantly higher in DPSC-DOs than DPSCs (P = .021). The methylation of Alu was not significantly different between DPSCs and DPSC-DOs.
conclusionsMethylation alterations of LINE-1 but not Alu were found in osteogenic differentiation of DPSCs. The results of this study offer foundational insights into osteoblast differentiation from an epigenetic perspective and may contribute to advancements in bone regeneration therapy in the future.
