Abstract

Recent work has suggested that environmental chemicals, including those contained in cigarette smoke, can have adverse effects on the exposed individuals as well as their future progeny. The mechanisms underlying transmission of environmentally induced phenotypes through the germ line are not well understood. However, a predominant process appears to be the establishment of permanent heritable epigenetic alterations, and a number of studies have implicated microRNAs in such processes. Here, we show that cigarette smoke induces specific differences in the spermatozoal microRNA content of human smokers compared with non-smokers, and that these altered microRNAs appear to predominantly mediate pathways vital for healthy sperm and normal embryo development, particularly cell death and apoptosis. microRNA-mediated perturbation of such pathways may explain how harmful phenotypes can be induced in the progeny of smokers.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Smoking was later found to be associated with reduced sperm count, motility and morphology, and altered sperm microRNA, mitochondria and protein in the smoker parent.

    From Intergenerational transmission of trauma effects: putative role of epigenetic mechanisms (2018) · cites this paper as [202]

    The Discussion reports altered sperm microRNA expression in smokers. But the Study population section reports no significant difference in sperm count, motility, or morphology between smokers and non-smokers. The cited passages do not establish altered sperm mitochondria or protein; the reported Ston1 and TRIM26 changes concern mRNA expression. Page numbers are unavailable in our copy. (LLM, conf=0.90)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
