The coculture of in vitro produced porcine embryos and oviductal epithelial cells improves blastocyst formation and modify embryo quality. Theriogenology 2024; 226:141-150. [PMID: 38885555 DOI: 10.1016/j.theriogenology.2024.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 06/11/2024] [Accepted: 06/11/2024] [Indexed: 06/20/2024]
Abstract
The efficiency of in vitro embryo production in mammals is influenced by variables associated with culture conditions during maturation, fertilization, and embryonic development. The embryos obtained often exhibit low quality due to suboptimal in vitro culture conditions compared to the in vivo environment. Co-culturing gametes and embryos with somatic cells has been developed to enhance in vitro culture conditions. This study aimed to assess the impact of coculturing in vitro-produced porcine embryos with porcine oviductal epithelial cells (POEC) on embryo development and quality. Firstly, a pure culture of POEC suitable for coculture systems was established. The epithelial origin of the cells was confirmed by the expression of E-cadherin and cytokeratin. The expression pattern of hormone receptors aligned with the diestrous oviduct, and POEC also secreted oviductal glycoprotein type 1 (OVGP-1). Secondly, POEC from passage 1 (POEC-1) were used to coculture with in vitro-produced porcine embryos. A successful coculture system was established without the addition of fetal bovine serum as a supplement. Coculturing POEC-1 in monolayers with in vitro-produced porcine embryos during the initial two days of culture enhanced the percentage of blastocysts and their hatching. Although the coculture did not alter the number of cells in the blastocysts or apoptosis assessed by TUNEL, it significantly reduced reactive oxygen species (ROS) levels in cleaved porcine embryos. This study represents the first report evaluating the quality of porcine embryos produced by IVF in coculture systems and assessing ROS levels in cleaved porcine embryos obtained by IVF.

Kumar S, Chaves MS, Ferreira ACA, Bezerra da Silva AF, Pereira LMC, Vale WG, Filho STR, Watanabe YF, Melo LM, Figueirêdo Freitas VJD. Oocyte competence and gene expression in parthenogenetic produced embryos from repeat breeder and normally fertile buffaloes (Bubalus bubalis) raised in sub-humid tropical climate. Anim Reprod Sci 2024; 262:107426. [PMID: 38377631 DOI: 10.1016/j.anireprosci.2024.107426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 01/20/2024] [Accepted: 01/29/2024] [Indexed: 02/22/2024]
Abstract
The reproductive management of the buffalo species still faces several unresolved problems, which directly affect the productivity of the herd, one of them being the presence of repeat breeder females. Given this scenario, this study aimed to verify the developmental competence of oocytes obtained from repeat breeder females and submitted to parthenogenetic activation. In addition, embryo gene expression was compared to normally fertile females. Murrah buffaloes were divided into two groups: repeat breeder (RB, n = 8) and normally fertile or control (CR, n = 7). Cumulus-oocyte complexes (COCs) were aspirated by transvaginal ovum pick-up from estrus synchronized females. The COCs were submitted to IVM for 24 h, and subsequently, the oocytes were activated using ionomycin, followed by 6-DMAP. Afterwards, the presumptive parthenotes were cultured for six or seven days in a microenvironment of 5 % CO2, 5 % O2, and 90 % N2 at 38.5 °C. The expression of OCT4, GLUT1, BCL2 and TFAM genes from blastocysts was evaluated. The overall COCs recovery rate was 70.9 % (190/268). The maturation (57.8 vs 71.1), cleavage (45.2 vs 62.2) and blastocyst (30.1 vs 45.9) rates did not differ (P > 0.05) between RB and CR females, respectively. Similarly, no significant difference (P > 0.05) was observed for the expression of studied genes in both RB and CR females. In conclusion, oocytes obtained from RB were as developmentally competent as those collected from CR females, with similar energy metabolism and in vitro development capacity. Thus, the low fertility rate of repeat breeder buffaloes, when compared to normal cyclic females, must be due to subsequent events to the blastocyst stage.

Inhibition of the pyroptosis-associated inflammasome pathway: The important potential mechanism of ginsenosides in ameliorating diabetes and its complications. Eur J Med Chem 2023; 253:115336. [PMID: 37031528 DOI: 10.1016/j.ejmech.2023.115336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 04/01/2023] [Accepted: 04/02/2023] [Indexed: 04/08/2023]
Abstract
Diabetes mellitus (DM) and its complications have become an important global public health issue, affecting human health and negatively impacting life and lifespan. Pyroptosis is a recently discovered form of pro-inflammatory programmed cell death (PCD). To date, pyroptosis-associated inflammasome pathways have been identified primarily in the canonical and non-canonical inflammasome pathway, apoptotic caspase-mediated pathway, granzyme-mediated pathway, and streptococcal pyrogenic exotoxin B (SpeB)-mediated pathway. The activation of diabetes-mediated pyroptosis-associated factors play an important role in the pathophysiology of DM and its complications. Studies have shown that ginsenosides exert significant protective effects on DM and its complications. Through inhibiting the activation of pyroptosis-associated inflammasome pathways, and then the DM and its complications are improved. This review summarizes the subtypes of ginsenosides and their chemical characteristics, pharmacokinetics and side effects, the main pyroptosis-associated inflammasome pathways that have been discovered to date, and the potential mechanism of different subtypes of ginsenosides in the treatment of DM and its complications (such as diabetic cardiomyopathy, diabetic nephropathy, diabetic liver injury, diabetic retinopathy, and diabetic ischemic stroke) via anti-pyroptosis-associated inflammasome pathways. These findings may provide ideas for further research to explore ginsenoside mechanism in improving DM and its complications. However, many pyroptosis-associated inflammasome pathways and targets involved in the occurrence and development of DM and its complications are still unknown. In the future, further studies using in vitro cell models, in vivo animal models, and human disease models can be used to further elucidate the mechanism of ginsenosides in the treatment of DM and its complications.

Ginsenoside Rg1 Inhibits High Glucose-Induced Proliferation, Migration, and Angiogenesis in Retinal Endothelial Cells by Regulating the lncRNA SNHG7/miR-2116-5p/SIRT3 Axis. JOURNAL OF ONCOLOGY 2022; 2022:6184631. [PMID: 36510610 PMCID: PMC9741534 DOI: 10.1155/2022/6184631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 08/22/2022] [Accepted: 08/26/2022] [Indexed: 12/04/2022]
Abstract
Background Diabetic retinopathy (DR), including retinal angiogenesis and endothelial cell proliferation and migration, is a serious complication in diabetic patients. It has been reported that ginsenoside Rg1 can prevent retinal damage. However, the mechanism by which Rg1 prevents retinal damage is unknown. Therefore, the aim of the present study was to investigate the mechanism by which Rg1 inhibits high glucose-induced complications through the regulation of the lncRNA SNHG7/miR-2116-5p/SIRT3 axis. Methods Under high glucose (HG) conditions, human retinal endothelial cells (HRECs) were cultured to simulate a DR environment, and Rg1 was added after 48 h. Negative control (NC), miR-2116-5p mimic, si-SNHG7, pc-DNA SIRT3, and miR-2116-5p inhibitor were transfected into HRECs, and CCK-8 assay was used to detect the cell viability. Angiogenesis and transwell assays were used to evaluate angiogenesis and cell migration, respectively. qRT-PCR and Western blot were used to detect the expression of related genes and proteins. Luciferase reporter assays and bioinformatics were used to analyze the target binding sites of miR-2116-5p to lncRNA SNHG7 and SIRT3. Results The proliferation, migration and angiogenesis of HRECs were induced by HG. As expected, HG upregulated miR-2116-5p and VEGF expression but downregulated lncRNA SNHG7 and SIRT3 expression. Importantly, Rg1 inhibited HG-induced HREC proliferation, migration, and angiogenesis by upregulating the lncRNA SNHG7, and miR-2116-5p had a target regulatory relationship with both lncRNA SNHG7 and SIRT3. Conclusion Rg1 inhibits HG-induced proliferation, migration, angiogenesis, and VEGF expression in retinal endothelial cells through the lncRNA SNG7/miR-2116-5p/SIRT3 axis. This finding provides theoretical evidence for the clinical application of Rg1 in DR.

Linoleic acid reduces apoptosis via NF-κB during the in vitro development of induced parthenogenic porcine embryos. Theriogenology 2022; 187:173-181. [PMID: 35596974 DOI: 10.1016/j.theriogenology.2022.05.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 05/06/2022] [Accepted: 05/09/2022] [Indexed: 11/22/2022]
Abstract
Fatty acid has a various role in preimplantation embryo development. Especially, Linoleic acid, polyunsaturated fatty acid, has been reported to affect the apoptosis pathway via nuclear transcription factor-kappa B. But to date, the function of NF-κB has not been demonstrated in porcine preimplantation embryos. We demonstrated that linoleic acid had a positive effect on embryo development at a certain concentration(25 μM), but developmental failure was observed at higher concentration. Furthermore, the expression level of NF-κB increased, unlike that of IL-6, as the concentration of linoleic acid increased. Interestingly, the concentration of NF-κB was found to increase even at the concentration of linoleic acid at which embryo development decreased. We found that pro-apoptotic gene expression was downregulated in the linoleic acid-treated group. It was also found that MCL-1, an anti-apoptotic gene known to be unaffected by IL-6, was found to be increased at the mRNA level in the linoleic acid-treated group. As the concentration of NF-kB increased, the nuclear translocation of C-JUN gradually increased dependent on the linoleic acid concentration. It was confirmed that NF-κB is an important factor in porcine embryos by treated ammonium pyrrolidinedithiocarbamate (APDC 0.1 μM, an inhibitor of NF-κB) affected NF-κB protein expression, IL-6 expression, and blastocyst production. These data supported porcine embryos can use exogenous linoleic acid as a metabolic energy source via NF-κB.

Abstract
This paper demonstrates that ginseng mixtures and individual ginseng chemical constituents commonly induce hormetic dose responses in numerous biological models for endpoints of biomedical and clinical relevance, typically providing a mechanistic framework. The principal focus of ginseng hormesis-related research has been directed toward enhancing neuroprotection against conditions such as Alzheimer's and Parkinson's Diseases, stroke damage, as well as enhancing spinal cord and peripheral neuronal damage repair and reducing pain. Ginseng was also shown to reduce symptoms of diabetes, prevent cardiovascular system damage, protect the kidney from toxicities due to immune suppressant drugs, and prevent corneal damage, amongst other examples. These findings complement similar hormetic-based chemoprotective reports for other widely used dietary-type supplements such as curcumin, ginkgo biloba, and green tea. These findings, which provide further support for the generality of the hormetic dose response in the biomedical literature, have potentially important public health and clinical implications.
