Impact of Secondhand Smoke and E-Cigarette Exposure on Placental Apoptotic and Growth-Regulatory Proteins in Mouse Pregnancy.
Article in Cells, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Apoptosis is critical in placental development, and its dysregulation is linked to pregnancy complications such as intrauterine growth restriction (IUGR) and preeclampsia (PE). Environmental exposures, particularly secondhand smoke (SHS) and e-cigarettes (eCigs), may contribute to placental dysfunction through apoptotic pathways. This study examined the effects of SHS and eCig exposure on placental apoptosis and growth-regulatory proteins in a murine model. C57BL/6 pregnant mice were exposed to SHS or eCigs at two critical gestational time points: early trophoblast invasion (E12.5 to E18.5) and established invasion (E14.5 to E18.5). Placental tissues were collected and analyzed for pro-apoptotic and anti-apoptotic markers, heat shock proteins, insulin-like growth factor-binding proteins (IGFBPs), and growth regulators. SHS exposure increased pro-apoptotic markers (BAD, Fas/FasL) and decreased mitochondrial function markers (cytochrome c), indicating compromised cellular survival. Both SHS and eCig exposure reduced anti-apoptotic markers (BCL-2, HSP27, survivin) and growth regulators (IGF-1, IGFBPs). SHS and eCig exposure create a pro-apoptotic environment in the placenta, potentially impairing fetal development through altered apoptotic and growth-regulatory pathways. These findings underscore the risks of environmental exposures during pregnancy, highlighting the need for strategies to minimize maternal exposure to SHS and eCigs.
