Absence of PARP-1 affects Cxcl12 expression by increasing DNA demethylation.
Article in Journal of cellular and molecular medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Poly [ADP-ribose] polymerase 1 (PARP-1) has an inhibitory effect on C-X-C motif chemokine 12 gene (Cxcl12) transcription. We examined whether PARP-1 affects the epigenetic control of Cxcl12 expression by changing its DNA methylation pattern. We observed increased expression of Cxcl12 in PARP-1 knock-out mouse embryonic fibroblasts (PARP1-/-) in comparison to wild-type mouse embryonic fibroblasts (NIH3T3). In the Cxcl12 gene, a CpG island is present in the promoter, the 5' untranslated region (5' UTR), the first exon and in the first intron. The methylation state of Cxcl12 in each cell line was investigated by methylation-specific PCR (MSP) and high resolution melting analysis (HRM). Both methods revealed strong demethylation in PARP1-/- compared to NIH3T3 cells in all four DNA regions. Increased expression of the Ten-eleven translocation (Tet) genes in PARP1-/- cells indicated that TETs could be important factors in Cxcl12 demethylation in the absence of PARP-1, accounting for its increased expression. Our results showed that PARP-1 was a potential upstream player in (de)methylation events that modulated Cxcl12 expression.
