Acrylamide disrupts meiotic G2/M transition and SAC activity during oocyte maturation.

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
Acrylamide is a synthetic material which is widely used in water treatment and paper manufacturing, and it is also generated from food formation, which shows neurological effects, skin irritation, or reproductive toxicity. Several studies focused on the effects of acrylamide on mitochondria and apoptosis in oocytes. In present study, we reported that acrylamide disturbed cell cycle progression of mouse oocyte meiosis. Our data showed that acrylamide caused both germinal vesicle (GV) breakdown and polar body extrusion defects. Further analysis indicated that acrylamide induced DNA damage in the GV oocytes, showing with increased γ-H2A.X expression, which active CHK2 for G2/M transition. This could be confirmed by the altered Cyclin B1 and CDK1 expression in oocytes. Besides, we found kinetochore-microtubule attachment was aberrant in metaphase I (MI) oocytes, which active spindle assembly checkpoint (SAC) for polar body extrusion, and this was confirmed by the consistent presentence of BubR1 and Bub3. This was due to the reduced tubulin acetylation-based microtubule stability, since HDAC6 and NAT10 expression was changed and cold treatment reduced the tubulin polymerization. Taken together, our study reported that acrylamide exposure disrupted cell cycle progression through DNA damage-based MPF activity and tubulin acetylation-based SAC activation in oocytes.
