Visfatin exerts an anti-proliferative and pro-apoptotic effect in the human placenta cells†.

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
Visfatin regulates energy homeostasis, metabolism, inflammation, and reproduction via the hypothalamus-pituitary-ovary axis. Our previous study showed the visfatin gene and protein expression in the human placenta. This study aimed to investigate the in vitro effect of visfatin on the proliferation and apoptosis of placental JEG-3 and BeWo cells but also in villous explants collected from normal pregnancies and complicated by intrauterine growth restriction (IUGR), preeclampsia (PE), and gestational diabetes mellitus (GDM). We studied placenta cells viability, proliferation, cell cycle, proliferation/apoptotic factors and insulin receptor (INSR) expression, DNA fragmentation, CASP3/7 activity, and phosphorylation of ERK1/2, AKT, AMPKα, STAT3 with their involvement after pharmacological inhibition in visfatin action on proliferation and apoptosis. Visfatin (1, 10, 100 ng/mL) decreased the viability and proliferation of JEG-3 after 48 h, and a similar effect was observed via co-administration of visfatin (10 ng/mL) and insulin (10 ng/mL) in JEG-3 and BeWo after 48 h and 72 h, respectively. Visfatin reduced the transition from the G2/M phase, and expression of PCNA or cyclins D, E, A, and B in JEG-3 and PCNA in normal, IUGR, PE, and GDM placentas. It increased DNA fragmentation, CASP3/7 activity, P53, BAX/BCL2, CASP9, CASP 8, CASP3 levels in BeWo, and CASP3 expression in tested placentas. Furthermore, visfatin modulated INSR, ERK1/2, AKT, AMPKα, and STAT3 expression in JEG-3 and BeWo, and its anti-proliferative and pro-apoptotic effects occurred via mentioned factors. In conclusion, visfatin, by affecting the proliferation and apoptosis of human placenta cells, may be an important factor in the development and function of the organ.
