[PMID: 36933589 DOI: 10.1016/j.ijbiomac.2023.124026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 03/07/2023] [Accepted: 03/08/2023] [Indexed: 03/18/2023]
Abstract
Bone morphogenetic protein 15 (BMP15) is specifically expressed in oocytes in pigs at all stages from early stages to ovulation and has an important role in oocyte maturation. However, there are few reports on the molecular mechanisms by which BMP15 affects oocyte maturation. In this study, we identified the core promoter region of BMP15 using a dual luciferase activity assay and successfully predicted the DNA binding motif of the transcription factor RUNX1. The effect of BMP15 and RUNX1 on oocyte maturation was examined using the first polar body extrusion rate, a reactive oxygen species (ROS) assay and total glutathione (GSH) content at three time points of 12, 24 and 48 h of in vitro culture of porcine isolated oocytes. Subsequently, the effect of the transcription factor RUNX1 on the TGF-β signaling pathway (BMPR1B and ALK5) was further verified using RT-qPCR and Western blotting. We found that the overexpression of BMP15 significantly increased the first polar body extrusion rate (P < 0.01) and total glutathione content of oocytes cultured in vitro for 24 h and decreased reactive oxygen levels (P < 0.01), whereas interference with BMP15 decreased the first polar body extrusion rate (P < 0.01), increased reactive oxygen levels in oocytes cultured in vitro for 24 h (P < 0.01), and decreased glutathione content (P < 0.01). The dual luciferase activity assay and online software prediction showed that RUNX1 is a potential transcription factor binding to the core promoter region (-1203/-1423 bp) of BMP15. Overexpression of RUNX1 significantly increased the expression of BMP15 and oocyte maturation rate, while inhibition of RUNX1 decreased the expression of BMP15 and the oocyte maturation rate. Moreover, the expression of BMPR1B and ALK5 in the TGF-β signaling pathway increased significantly after overexpression of RUNX1, whereas their expression decreased after inhibition of RUNX1. Overall, our results suggest that the transcription factor RUNX1 positively regulates the expression of BMP15 and influences oocyte maturation through the TGF-β signaling pathway. This study provides a theoretical basis for further complementing the BMP15/TGF-β signaling pathway to regulate mammalian oocyte maturation.

Abstract
The transfer of nuclear genomic DNA from a cell to a previously enucleated oocyte or zygote constitutes one of the main tools for studying epigenetic reprogramming, nucleus-cytoplasm compatibility, pluripotency state, and for genetic preservation or edition in animals. More than 50 years ago, the first experiences in nuclear transfer began to reveal that factors stored in the cytoplasm of oocytes could reprogram the nucleus of another cell and support the development of an embryo with new genetic information. Furthermore, when the nuclear donor cell is an oocyte, egg, or a zygote, the implementation of these technologies acquires clinical relevance for patients with repeated failures in ART associated with poor oocyte quality or mitochondrial dysfunctions. This review describes the current state, scope, and future perspectives of nuclear transfer techniques currently available for assisting mammal reproduction.

Abstract
The aim of this study was to produce porcine tetraploid (4N) parthenogenetic
embryos using various methods and evaluate their developmental potential. In
method 1 (M1), porcine 4N parthenogenetic embryos were obtained by inhibiting
extrusion of both first (PB1) and second (PB2) polar bodies; in methods 2 (M2)
and 3 (M3), 4N parthenogenetic embryos were obtained by electrofusion of 2-cell
stage diploid parthenogenetic embryos derived from inhibition of PB2 or PB1
extrusion, respectively. We found no differences in the rates of cleavage or
blastocyst formation or the proportion of 4N embryos among M1, M2, and M3
groups. The different methods also did not influence apoptosis rates (number of
TUNEL-positive cells/number of total cells) or expression levels of
apoptosis-related BAX and BCL2L1 genes.
However, total cell and EdU (5-ethynyl-2’-deoxyuridine)-positive cell
numbers in 4N parthenogenetic blastocysts derived from M1 were higher
(p < 0.05) than those for M2 and M3 groups. Our
results suggest that, although porcine 4N parthenogenetic embryos could be
produced by a variety of methods, inhibition of PB1 and PB2 extrusion (M1) is
superior to electrofusion of 2-cell stage diploid parthenogenetic embryos
derived from inhibition of PB2 (M2) or PB1 (M3) extrusion.

Abstract
As a natural plant-derived antitoxin, resveratrol possesses several pharmacological activities. This study aimed to evaluate the effects of resveratrol addition on nuclear maturation, oocyte quality during in vitro maturation (IVM) of porcine oocytes and subsequent early embryonic development following somatic cell nuclear transfer (SCNT). Our experiments showed that the treatment of porcine oocytes with 5 µM resveratrol during IVM resulted in the highest rate of the first polar body extrusion. Treatment of oocytes with resveratrol had no influence on cytoskeletal dynamics, whereas it significantly increased glucose uptake ability compared to the control oocytes. Oocytes matured with 5 μM resveratrol displayed significantly lower intracellular reactive oxygen species (ROS) levels and higher relative mRNA expression levels of the genes encoding such antioxidant enzymes as catalase (CAT) and superoxide dismutase 1 (SOD1). In addition, resveratrol also prevented onset and progression of programmed cell death in porcine oocytes, which was confirmed by significant upregulation of the anti-apoptotic B-cell lymphoma 2 (BCL-2) gene and significant downregulation of the pro-apoptotic BCL2-associated X (BAX) gene. Furthermore, the blastocyst rates and the blastocyst cell numbers in cloned embryos derived from the oocytes that had matured in the presence of 5 μM resveratrol were significantly increased. In conclusion, supplementation of IVM medium with 5 μM resveratrol improves the quality of porcine oocytes by protecting them from oxidative damage and apoptosis, which leads to the production of meiotically matured oocytes exhibiting enhanced developmental potential following SCNT.

Procedure used for denuding pig oocytes influences oocyte damage, and development of in vitro and nuclear transfer embryos. Anim Reprod Sci 2014; 152:65-76. [PMID: 25487568 DOI: 10.1016/j.anireprosci.2014.11.009] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2014] [Revised: 11/10/2014] [Accepted: 11/11/2014] [Indexed: 11/20/2022]
Abstract
The effects of different denuding procedures used during the in vitro culture of porcine embryos on oocyte damage and aspects of porcine embryo development were investigated in a series of studies. Oocytes were denuded by vortexing or pipetting after 44h in vitro maturation (IVM) or pre-denuded after 22h IVM. The total oocyte death rate was significantly (P<0.05) higher for pre-denuded (27.3±1.4%) than for vortexed (20.3±1.2%) or pipetted (16.2±2.2%) oocytes. There was no significant difference between the treatments in the percentage of oocytes that extruded the first polar body. The type I cortical granule distribution (reflecting complete maturity) and normal spindle formation rates were significantly lower in the pre-denuding than in the vortexing and pipetting treatments. Blastocyst formation rates were significantly lower for the pre-denuding treatment in PA (25.7±4.5%) and IVF (6.1±1.5%) culture than in the vortexing (PA 42.0±4.5%; IVF 11.2±0.5%) and pipetting (PA 43.4±3.1%; IVF 9.4±1.6%) treatments. The proportion of oocytes developing to blastocysts in SCNT culture was not significantly different between treatments ranging from 9.9±1.8% for pre-denuding to 12.3±2.7% for vortexing. No significant differences in apoptosis or embryonic fragmentation were observed. This study shows that the denuding procedure used for porcine oocytes during the in vitro production of embryos can significantly affect oocyte damage, spindle patterns, oocyte maturation, embryo development but not embryonic apoptosis or the frequency of fragmentation.
