Qualitative research of alternatively splice variants of fibronectin in different development stage of mice heart.
Article in Journal of thoracic disease, 2015. 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
backgroundFibronectin (FN) plays vital roles in cell adhesion, differentiation, proliferation and migration. It is involved in the process of embryonic development and is highly conserved during evolution. The EIIIA and EIIIB of FN show a very high degree of homology among vertebrates. Embryos deleting both EIIIA and EIIIB displayed multiple embryonic cardiovascular defects, implying their crucial role during embryogenesis. The correlation of spliced EIIIB, EIIIA, and IIICS of FN to heart development was studied by observing their chronological expression in mice heart.
methodsC57 mice embryos at E11.5, E12.5, E13.5, E14.5, E15.5, E16.5, E17.5, E18.5, E19.5 days, postnatal day 1 (P1d), and adult male mice (3 months) were used. For each alternatively spliced FN1 domain (EIIIB, EIIIA and IIICS), primer pairs were designed for specific amplification. Total RNA was extracted from the heart tissue, reverse transcripted to cDNA, followed by RT-PCR with specific primers. The PCR amplification was verified by agarose gel electrophoresis, showing specific fragments of the expected sizes.
resultsIn adult mice heart, only alternatively splice variants of EIIIA-, EIIIB-, IIICS+ were expressed. While in embryonic mice, spliced variant of EIIIA+/-, EIIIB+/-, IIICS+ were observed. The expression of EIIIA and EIIIB changed during heart development.
conclusionsFN is crucial for the normal development of the embryonic heart by modulating cardiac neural crest (CNC) proliferation and survival, and maintenance of CNC cells. FN1 gene seems to play a significant role by expression of highly conserved EIIIA and EIIIB in embryonic heart development.
