Effects of cigarette smoke extract on angiogenesis and aromatase activity in KGN cells.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Cigarette smoking is associated with negative reproductive outcomes and an increased likelihood of failed in vitro fertilization. We investigated the impact of cigarette smoke on angiogenesis and aromatase activity in human granulosa cells. The human ovarian granulosa-like tumor cell line (KGN) was exposed to different cigarette smoke extract (CSE) concentrations and/or 10-μM forskolin. mRNA and protein levels and their secretion were measured using real-time polymerase chain reaction, western blotting, and enzyme-linked immunosorbent assay techniques, respectively. Additionally, KGN cells were transfected with small interfering RNA (siRNA) targeting hypoxia-inducible factor-1α (HIF-1α) for 24 h, followed by treatment with or without (control) CSE for 48 h. Data were statistically analyzed. Compared with the control group, the CSE group showed significantly increased vascular endothelial growth factor (VEGF), N-myc downstream-regulated gene 1 (NDRG1), and HIF-1α expression. Overexpression of VEGF and NDRG1 induced by CSE was inhibited by HIF-1α siRNA transfection. Furthermore, CSE exposure decreased progesterone and estradiol levels and increased testosterone levels. It also affected the expression of genes associated with steroid hormone synthesis, decreased anti-Müllerian hormone and anti-Müllerian hormone receptor II levels, and caused SMAD signaling pathway desensitization. Thus, CSE adversely affects the maturation of human granulosa cells, affecting both angiogenesis and aromatase activity.
