MiR-17-3p inhibits osteoblast differentiation by downregulating Sox6 expression.
Article in FEBS open bio, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Osteoporosis and osteoarthritis are orthopedic disorders that affect millions of elderly people worldwide; stimulation of bone formation is a potential therapeutic strategy for the treatment of these conditions. As the only bone-forming cells, osteoblasts play a key role in bone reconstruction. The microRNA miR-17-3p is downregulated during osteogenic differentiation of human bone marrow mesenchymal stem cells, but its precise role in this process is unknown. Here, we investigated the role of miR-17-3p in osteoblast differentiation. An in vitro model of osteogenesis was established by treating MC3T3-E1 murine preosteoblast cells with bone morphogenetic protein 2 (BMP2). The expression of miR-17-3p in BMP2-induced MC3T3-E1 cells was detected by reverse transcription-quantitative PCR, and its effects on cells transfected with miR-17-3p mimic or inhibitor were evaluated by Alizarin Red staining, alkaline phosphatase (ALP) activity assay, and by detection of osteoblast markers including the ALP, collagen type I α1 chain, and osteopontin genes. Bioinformatics analysis was carried out to identify putative target genes of miR-17-3p, and the luciferase reporter assay was used for functional validation. Rescue experiments were performed to determine whether SRY-box transcription factor 6 (Sox6) plays a role in the regulation of osteoblast differentiation by miR-17-3p. We report that miR-17-3p was downregulated upon BMP2-induced osteoblast differentiation in MC3T3-E1 cells, and this was accompanied by decreased differentiation and mineralization, ALP activity, and expression of osteogenesis-related genes. Sox6 was confirmed to be a target gene of miR-17-3p in osteoblasts, and the inhibitory effect of miR-17-3p on osteoblast differentiation was observed to occur via Sox6. These results suggest the existence of a novel mechanism underlying miRNA-mediated regulation of osteogenesis, which has potential implications for the treatment of orthopedic disorders.
