bmo-miR-275 down-regulates expression of Bombyx mori sericin gene 2 in vitro.
Article in PloS one, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
We hypothesized that bmo-miR-275 has a potential regulatory function regarding the expression of sericin gene 2 (BmSer-2). First, we examined the expression of bmo-miR-275 and its target gene BmSer-2 in seven different tissues from 5th instar day-3 silkworm larvae. The results showed that they were both specifically expressed in the middle silk gland, implying that spatio-temporal conditions are required for bmo-miR-275 to regulate the expression of BmSer-2. To test this hypothesis, we constructed a pri-bmo-miR-275 expressing plasmid pcDNA3.0 [ie1-egfp-pri-bmo-miR-275-SV40] and BmSer-2-3´UTR recombinant reporter plasmids pGL3.0 [A3-luc-Ser-2-3' UTR-SV40]. Finally, BmN cells were harvested and luciferase activity was detected. Results showed that luciferase activity was reduced significantly (P<0.05) in BmN cells co-transfected with pcDNA3.0 [ie1-egfp-pri-bmo-miR-275-SV40] and pGL3.0 [A3-luc-Ser-2-3'UTR-SV40], suggesting that bmo-miR-275 can down-regulate the expression of BmSer-2 in vitro. Our results improve the understanding of the regulatory function of Bombyx mori miRNA on the expression of genes regulating silk formation.
