Pyrroloquinoline quinone promotes porcine oocyte in vitro maturation and subsequent embryo development by enhancing lipid metabolism and improving mitochondrial function.
Article in Animal bioscience, 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
objectiveThe present study evaluated the beneficial effects of pyrroloquinoline quinone (PQQ) on in vitro maturation (IVM) of porcine oocyte and subsequent early embryo development.
methodsPorcine cumulus oocyte complexes were cultured in IVM medium with supplementation of 0, 200, 400, 800 or 1600 nM PQQ for 42 h. We first examined cumulus expansion index (CEI) and the rate of oocyte nuclear maturation. Then, we assessed oocyte mitochondrial function, oxidative stress levels, lipid metabolism and subsequent embryonic development.
resultsPQQ (800 nM) supplementation significantly increased CEI and the nuclear maturation rate of oocytes following IVM. Additionally, oocysts supplemented with 800 nM of PQQ showed significantly increased mitochondrial content, mitochondrial membrane potential, activity, and mRNA expression levels of genes associated with mitochondrial biogenesis (PGC-1a, NRF1, NRF2 and TFAM). PQQ significantly reduced the levels of reactive oxygen species, lipid drop-lets, and fatty acids content, while enhancing the mRNA expression levels of genes related to antioxidant activity (SOD1, SOD2, GPX and CAT), lipolysis (ATGL and HSL) and β-oxidation (CPT1B and CPT2) in porcine oocytes. PQQ (800 nM) supplementation significantly increased cleavage rate, blastocyst formation rate, and total blastocyst cell numbers following partheno-genetic activation.
conclusionPQQ supplementation during IVM positively influences porcine oocyte maturation and subse-quent embryonic development by enhancing mitochondrial function and lipid metabolism and alleviating oxidative stress.
