In vitro evaluation of ginsenoside Rg1 immunostimulating effect in bovine mononuclear cells. Res Vet Sci 2023; 158:1-12. [PMID: 36898322 DOI: 10.1016/j.rvsc.2023.03.003] [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: 01/24/2022] [Revised: 03/01/2023] [Accepted: 03/03/2023] [Indexed: 03/08/2023]
Abstract
The aim of this study was to evaluate the immunomodulatory effect of ginsenoside Rg1 on mammary secretion and peripheral blood mononuclear cells (MSMC and PBMC, respectively). The mRNA expression of TLR2, TLR4 and selected cytokines were evaluated on MSMC after Rg1 treatment. Also, TLR2 and TLR4 protein expression was evaluated on MSMC and PBMC after Rg1 treatment. Phagocytic activity and capacity, ROS production and MHC-II expression were evaluated on MSMC and PBMC after Rg1 treatment and co-culture with Staphylococcus aureus strain 5011. Rg1 induced mRNA expression of TLR2, TLR4, TNF-α, IL-1β, IL-6 and IL-8 in groups treated with different concentrations and at different times in MSMC, and induced TLR2 and TLR4 protein expression in MSMC and PBMC. Rg1 increased phagocytic capacity and ROS production in MSMC and PBMC. Rg1 increased MHC-II expression by PBMC. However, Rg1 pre-treatment had no effect on cells co-cultured with S. aureus. In conclusion, Rg1 was able to stimulate several sensing and effector activities in these immune cells.

Abstract
Alternariol (AOH), a mycotoxin belonging to the genus Alternaria, has been shown to induce cytotoxicity, including apoptosis and cell cycle arrest, in several mammalian cell types. However, its effects on early-stage embryonic development require further investigation. Here, we have shown that AOH exerts embryotoxic effects on mouse blastocyst-stage embryos and long-term adverse effects on immunity in one-day-old newborn mice of the next generation. Significant apoptosis and decrease in total cell number, predominantly through loss of inner cell mass (ICM), and to a minor extent, trophectoderm (TE) cells, were observed in AOH-treated blastocysts. Moreover, AOH exerted detrimental effects on pre- and post-implantation embryo development potential and induced a decrease in fetal weight in in vitro development and embryo transfer assays. Injection of pregnant mice with AOH (1, 3 and 5 mg/kg body weight/day) for 4 days resulted in apoptosis of blastocyst-stage embryos and injurious effects on embryonic development from the zygote to blastocyst stage or embryo degradation and a further decrease in fetal weight. Furthermore, AOH exerted a long-term impact on the next generation, triggering a significant increase in total oxidative stress content and expression of genes encoding antioxidant proteins. Lower expression of CXCL1, IL-1β and IL-8 related to innate immunity was detected in liver tissue extracts obtained from one-day-old newborns of AOH-injected pregnant mice (5 mg/kg body weight/day) relative to their non-treated counterparts. In addition, ROS served as an upstream regulator of AOH-triggered apoptotic processes and impairment of embryonic development. Our collective results highlight the potential of AOH as an embryotoxic and immunotoxic risk factor during embryo and infant development stages in mice.

Ginsenoside RG1 enhances the paracrine effects of bone marrow-derived mesenchymal stem cells on radiation induced intestinal injury. Aging (Albany NY) 2020; 13:1132-1152.

Abstract
UNLABELLED Content and aims: Ginsenoside RG1 (RG1) is thought to enhance proliferation and differentiation of stem cell, however, its role on paracrine efficacy of stem cell remains unclear. Here we examined if and how RG1 enhances the paracrine effects of bone marrow-derived mesenchymal stem cells (BM-MSCs) on radiation induced intestinal injury (RIII). METHOD Irradiated rats randomly received intraperitoneal injection of conditioned medium (CM) derived from non-activated BM-MSCs (MSC-CM) or BM-MSCs pre-activated by RG-1 (RG1-MSC-CM). Intestinal samples were collected, followed by the evaluation of histological and functional change, apoptosis, proliferation, inflammation, angiogenesis and stem cell regeneration. The effects of heme oxygenase-1 (HO-1) were investigated using HO-1 inhibitor or siRNA. RESULT RG1 enhanced the paracrine efficacy of BM-MSCs partially through upregulation of HO-1. RG1-MSC-CM rather than MSC-CM significantly improved the survival and intestinal damage of irradiated rats via improvement of intestinal proliferation/apoptosis, inflammation, angiogenesis and stem cell regeneration in a HO-1 dependent mechanism. The mechanism for the superior paracrine efficacy of RG1-MSC-CM is related to a higher release of two pivotal cytokines VEGF and IL-6. CONCLUSION Our study revealed that RG1 enhances paracrine effects of BM-MSCs on RIII, providing a novel method for maximizing the paracrine potential of MSCs.

Abstract
The current study has focused on the effects of enniatin B (ENN B, a major mycotoxin produced by Fusarium fungi) on early embryonic development. In in vitro analysis, mouse blastocysts were incubated in medium with ENN B (0-40 μM) or 0.5% DMSO (control group) for 24 hours. In an animal study, blastocysts were collected from mice which were intravenously injected with ENN B (1, 3, 5, and 7mg/kg body weight/day) for 4 days in order to analyze apoptosis and necrosis via Annexin V/PI staining assay; and proliferation using dual differential staining. Exposure to low ENN B concentration (10 μM in vitro and 3 mg/kg/day in vivo) promoted Reactive Oxygen Species (ROS) generation and apoptosis in the Inner Cell Mass (ICM), the mass of cells inside the blastocyst, impairing post-implantation development alone. On the other hand, exposure to a higher ENN B concentration (40 μM in vitro and 7 mg/kg/day in vivo) induced ROS generation and decreased in intracellular ATP which encouraged necrotic processes in both trophectoderm (TE) and ICM of blastocysts leading to impaired implantation and post-implantation development. Moreover, 5 and 7 mg/kg/day ENN B intraperitoneal injection to female mice for 4 days has caused downregulation of CXCL1, IL-1β and IL-8 expressions and increased ROS generation in the liver of newborn mice. Over all, ENN B can induce apoptosis and/or necrosis depending on the treatment dosage in mouse blastocysts. ENN B-induced necrosis in blastocysts may exert long-term harmful effects on next-generation newborns.

[PMID: 32905254 DOI: 10.1093/toxres/tfaa043] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Revised: 05/27/2020] [Accepted: 06/02/2020] [Indexed: 12/26/2022] Open
Abstract
Previous studies have shown that berberine, an isoquinoline alkaloid isolated from several traditional Chinese herbal medicines, suppresses growth and induces apoptosis in some tumor cell lines. It has also been shown that berberine possesses anti-atherosclerosis and antioxidant activities in hyperlipidemic model rats. Our previous study in mice found that berberine causes harmful effects on preimplantation and postimplantation embryonic development, both in vitro and in vivo, by triggering reactive oxygen species (ROS)-mediated apoptotic cascades in mouse blastocysts. In the current investigation, we further showed that berberine treatment has distinct dose-dependent effects on oocyte maturation and subsequent development. Preincubation of oocytes with 2.5 μM berberine significantly enhanced maturation and in vitro fertilization (IVF) rates, with subsequent beneficial effects on embryonic development. In contrast, preincubation with 10 μM berberine negatively impacted mouse oocyte maturation, decreased IVF rates and impaired subsequent embryonic development. Similar dose-dependent effects were also demonstrated in vivo. Specifically, intravenous injection of berberine significantly enhanced mouse oocyte maturation, IVF rate and early-stage embryo development after fertilization at a dose of 1 mg/kg body weight but significantly impaired oocyte maturation and IVF rates and caused harmful effects on early embryonic development at a dose of 5 mg/kg. Mechanistically, we found that berberine enhanced intracellular ROS production and apoptosis of oocytes at a concentration of 10 μM but actually significantly decreased total intracellular ROS content and had no apoptotic effect at a concentration of 2.5 μM. Moreover, pretreatment of oocytes with Ac-DEVD-cho, a caspase-3-specific inhibitor, effectively blocked berberine-induced negative impacts on oocyte maturation, fertilization and subsequent development. Collectively, these findings establish the dose-dependent beneficial versus deleterious effects of berberine and suggest that the mechanism underlying the deleterious effects of berberine involves a caspase-3-dependent apoptotic process acting downstream of an increase in intracellular ROS levels.

Abstract
Ginsenoside Rb1 (GRb1), the major saponin component of ginseng root, has a wide range of therapeutic applications for various diseases. Previously, our group showed that GRb1 triggers ROS-mediated apoptotic cascades in mouse blastocysts, leading to decreased cell viability and impairment of pre- and postimplantation embryonic development, both in vitro and in vivo. In this study, we further found that GRb1 exerted dose-dependent effects on oocyte maturation and sequent development in vitro. Oocytes preincubated with 25 μg/mL GRB1 displayed significantly enhanced maturation and in vitro fertilization (IVF) rates, along with progression of subsequent embryonic development. In contrast, treatment with 50 and 100 μg/mL GRB1 led to impairment of mouse oocyte maturation, decreased IVF rates, and injurious effects on subsequent embryonic development. In vivo, intravenous injection of 1 mg/kg body weight GRb1 significantly promoted mouse oocyte maturation, IVF, and early-stage embryo development after fertilization while administration of 5 mg/kg body weight GRb1 led to a marked decrease in oocyte maturation and IVF rates concomitant with impairment of early embryonic development in our animal model. In terms of the mechanisms underlying the regulatory effects of GRb1 demonstrated increased intracellular reactive oxygen species (ROS) production and apoptosis in the 100 μg/mL GRb1 treatment group. However, we observed a significant decrease in total intracellular ROS content and inhibition of apoptosis events in the 25 μg/mL GRb1 treatment group, signifying that the intracellular ROS content serves as a key upstream regulator of GRb1 that influences its dose-dependent beneficial or deleterious effects on oocyte maturation and sequent embryonic development. For further clarification of the mechanisms underlying GRb1-triggered injurious effects, oocytes were pretreated with Ac-DEVD-CHO, a caspase-3-specific inhibitor, which effectively blocked injury to oocyte maturation, fertilization, and sequent development. In sum, study findings highlight the potential involvement of p53-, p21-, and caspase-3-dependent regulatory signaling cascades in GRb1-mediated apoptotic processes.

Abstract
Ochratoxin A (OTA), a mycotoxin constituent of a range of food commodities, including coffee, wine, beer, grains, and spices, exerts toxicological and pathological effects in vivo, such as nephrotoxicity, hepatotoxicity, and immunotoxicity. In a previous report, we highlighted the potential of OTA to induce apoptosis via reactive oxygen species (ROS) generation in mouse blastocysts that led to impaired preimplantation and postimplantation embryo development in vitro and in vivo. Here, we have shown that liquiritigenin (LQ), a type of flavonoid isolated from Glycyrrhiza radix, effectively protects against OTA-mediated apoptosis and inhibition of cell proliferation in mouse blastocysts. Preincubation of blastocysts with LQ clearly prevented OTA-triggered impairment of preimplantation and postimplantation embryonic development and fetal weight loss, both in vitro and in vivo. Detailed investigation of regulatory mechanisms revealed that OTA mediated apoptosis and embryotoxicity through ROS generation, loss of mitochondrial membrane potential (MMP), and activation of caspase-9 and caspase-3, which were effectively prevented by LQ. The embryotoxic effects of OTA were further validated in an animal model in vivo. Intravenous injection of dams with OTA (3 mg/kg/day) led to apoptosis of blastocysts, impairment of embryonic development from zygote to blastocyst stage and decrease in day 18 fetal weight. Notably, preinjection of dams with LQ (5 mg/kg/day) effectively prevented OTA-induced apoptosis and toxic effects on embryo development. Our collective results clearly demonstrate that OTA exposure via injection has the potential to damage preimplantation and postimplantation embryonic development against which LQ has a protective effect.

Abstract
Enniatins are mycotoxins of Fusarium fungi that naturally exist as mixtures of cyclic depsipeptides. Previous reports have documented hazardous effects of enniatins on cells, such as apoptosis. However, their effects on pre- and post-implantation embryonic development require further clarification. Here, we showed for the first time that enniatin B1 (ENN B1) exerts cytotoxic effects on mouse blastocyst-stage embryos and induces intracellular oxidative stress and immunotoxicity in mouse fetuses. Co-incubation of blastocysts with ENN B1 triggered significant apoptosis and led to a decrease in total cell number predominantly through loss of inner cell mass. In addition, ENN B1 appeared to exert hazardous effects on pre and postimplantation embryo development potential in an in vitro development assay. Treatment of blastocysts with 1-10 μM ENN B1 led to increased resorption of post-implantation embryos and decreased fetal weight in the embryo transfer assay in a dose-dependent manner. Importantly, in an in vivo model, intravenous injection with ENN B1 (1, 3, and 5 mg/kg body weight/d) for 4 days resulted in apoptosis of blastocyst-stage embryos and impairment of embryonic development from the zygote to blastocyst stage, subsequent degradation of embryos, and further decrease in fetal weight. Intravenous injection with 5 mg/kg body weight/d ENN B1 additionally induced a significant increase in total reactive oxygen species (ROS) content and transcription levels of genes encoding antioxidant proteins in mouse fetal liver. Moreover, ENN B1 triggered apoptosis through ROS generation and strategies to prevent apoptotic processes effectively rescued ENN B1-mediated hazardous effects on embryonic development. Transcription levels of CXCL1, IL-1β, and IL-8 related to innate immunity were downregulated after intravenous injection of ENN B1. These results collectively highlight the potential of ENN B1 to exert cytotoxic effects on embryos as well as oxidative stress and immunotoxicity during mouse embryo development.

Protective Effects and Target Network Analysis of Ginsenoside Rg1 in Cerebral Ischemia and Reperfusion Injury: A Comprehensive Overview of Experimental Studies. Cells 2018; 7:cells7120270. [PMID: 30545139 PMCID: PMC6316103 DOI: 10.3390/cells7120270] [Citation(s) in RCA: 115] [Impact Index Per Article: 19.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2018] [Revised: 12/07/2018] [Accepted: 12/10/2018] [Indexed: 12/14/2022] Open
Abstract
Cerebral ischemia-reperfusion is a complicated pathological process. The injury and cascade reactions caused by cerebral ischemia and reperfusion are characterized by high mortality, high recurrence, and high disability. However, only a limited number of antithrombotic drugs, such as recombinant tissue plasminogen activator (r-TPA), aspirin, and heparin, are currently available for ischemic stroke, and its safety concerns is inevitable which associated with reperfusion injury and hemorrhage. Therefore, it is necessary to further explore and examine some potential neuroprotective agents with treatment for cerebral ischemia and reperfusion injury to reduce safety concerns caused by antithrombotic drugs in ischemic stroke. Ginseng Rg1 (G-Rg1) is a saponin composed of natural active ingredients and derived from the roots or stems of Panax notoginseng and ginseng in traditional Chinese medicine. Its pharmacological effects exert remarkable neurotrophic and neuroprotective effects in the central nervous system. To explore and summarize the protective effects and mechanisms of ginsenoside Rg1 against cerebral ischemia and reperfusion injury, we conducted this review, in which we searched the PubMed database to obtain and organize studies concerning the pharmacological effects and mechanisms of ginsenoside Rg1 against cerebral ischemia and reperfusion injury. This study provides a valuable reference and clues for the development of new agents to combat ischemic stroke. Our summarized review and analysis show that the pharmacological effects of and mechanisms underlying ginsenoside Rg1 activity against cerebral ischemia and reperfusion injury mainly involve 4 sets of mechanisms: anti-oxidant activity and associated apoptosis via the Akt, Nrf2/HO-1, PPARγ/HO-1, extracellular regulated protein kinases (ERK), p38, and c-Jun N-terminal kinase (JNK) pathways (or mitochondrial apoptosis pathway) and the caspase-3/ROCK1/MLC pathway; anti-inflammatory and immune stimulatory-related activities that involve apoptosis or necrosis via MAPK pathways (the JNK1/2 + ERK1/2 and PPARγ/HO-1 pathways), endoplasmic reticulum stress (ERS), high mobility group protein1 (HMGB1)-induced TLR2/4/9 and receptor for advanced glycation end products (RAGE) pathways, and the activation of NF-κB; neurological cell cycle, proliferation, differentiation, and regeneration via the MAPK pathways (JNK1/2 + ERK1/2, PI3K-Akt/mTOR, PKB/Akt and HIF-1α/VEGF pathways); and energy metabolism and the regulation of cellular ATP levels, the blood-brain barrier and other effects via N-methyl-D-aspartic acid (NMDA) receptors, ERS, and AMP/AMPK-GLUT pathways. Collectively, these mechanisms result in significant neuroprotective effects against cerebral ischemic injury. These findings will be valuable in that they should further promote the development of candidate drugs and provide more information to support the application of previous findings in stroke clinical trials.

ENVIRONMENTAL TOXICOLOGY 2018; 33:1039-1049. [PMID: 29964317 DOI: 10.1002/tox.22590] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2018] [Revised: 06/01/2018] [Accepted: 06/04/2018] [Indexed: 06/08/2023]
Abstract
Silver nanoparticles (AgNPs) are antibacterial materials widely used in numerous products and medical supplies. Previously, we showed that AgNPs trigger apoptotic processes in mouse blastocysts, leading to a decrease in cell viability and impairment of preimplantation and postimplantation embryonic development in vitro and in vivo. In the present study, we further investigated the hazardous effects of AgNPs on mouse oocyte maturation, in vitro fertilization (IVF), and subsequent preimplantation and postimplantation development in vitro and in vivo. Data from in vitro experiments revealed that AgNPs impair mouse oocyte maturation, decrease IVF rates, and induce injury effects on subsequent embryonic development to a significant extent. In an animal model, intravenous injection of AgNPs (5 mg/kg body weight) led to a significant decrease in mouse oocyte maturation and IVF concomitant with impairment of early embryonic development in vivo. Importantly, pretreatment with N-acetylcysteine effectively prevented AgNP-triggered reactive oxygen species (ROS) production and apoptosis, clearly suggesting a critical role of ROS as an upstream initiator or key regulator of AgNP-induced hazardous effects on oocyte maturation and sequent embryonic development. Furthermore, preincubation of oocytes with Ac-DEVD-cho, a caspase-3-specific inhibitor, effectively prevented hazardous effects, highlighting the potential involvement of caspase-dependent apoptotic signaling cascades in AgNP-mediated events. Expression levels of p53 and p21 of blastocysts were upregulated upon preincubation of mouse oocytes with AgNPs. Our collective results imply that cell apoptosis in mouse blastocysts derived from the AgNP-pretreated oocytes via intracellular ROS generation, which is further mediated through p53-, p21-, and caspase-3-dependent regulatory mechanisms.

[PMID: 29168595 DOI: 10.1002/tox.22515] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/01/2017] [Revised: 11/02/2017] [Accepted: 11/07/2017] [Indexed: 06/07/2023]
Abstract
Berberine, an isoquinoline alkaloid isolated from several traditional Chinese herbal medicines, has been shown to suppress growth and induce apoptosis in some tumor cell lines. However, berberine has also been reported to attenuate H2 O2 -induced oxidative injury and apoptosis. The basis for these ambiguous effects of berberine-triggering or preventing apoptosis-has not been well characterized to date. In the current investigation, we examined whether berberine exerts cytotoxic effects on mouse embryos at the blastocyst stage and affects subsequent embryonic development in vitro and in vivo. Treatment of blastocysts with berberine (2.5-10 μM) induced a significant increase in apoptosis and a corresponding decrease in trophectoderm cell number. Moreover, the implantation success rate of blastocysts pretreated with berberine was lower than that of their control counterparts. Pretreatment with berberine was also associated with increased resorption of postimplantation embryos and decreased fetal weight. In an animal model, intravenous injection of berberine (2, 4, or 6 mg/kg body weight/d) for 4 days resulted in apoptosis of blastocyst cells and early embryonic developmental injury. Berberine-induced injury of mouse blastocysts appeared to be attributable to oxidative stress-triggered intrinsic apoptotic signaling processes that impaired preimplantation and postimplantation embryonic development. Taken together, our results clearly demonstrate that berberine induces apoptosis and retards early preimplantation and postimplantation development of mouse embryos, both in vitro and in vivo.

Int J Mol Sci 2017; 18:ijms18122538. [PMID: 29186930 PMCID: PMC5751141 DOI: 10.3390/ijms18122538] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2017] [Revised: 11/24/2017] [Accepted: 11/24/2017] [Indexed: 12/23/2022] Open
Abstract
The mycotoxin citrinin (CTN), a natural contaminant in foodstuffs and animal feeds, exerts cytotoxic and genotoxic effects on various mammalian cells and embryos. A previous investigation by our group revealed potentially hazardous effects of CTN on mouse oocyte maturation and pre- and post-implantation embryo development via the induction of apoptosis. The present study showed that CTN induces apoptosis and inhibits cell proliferation in the inner cell mass of mouse blastocysts. Notably, we observed for the first time that both these effects are suppressed by liquiritigenin (LQ). LQ is a type of flavonoid isolated from Glycyrrhiza radix with several biochemical and pharmacological activities, including antioxidant and anti-inflammatory properties. The preincubation of blastocysts with LQ clearly prevented CTN-induced disruption of pre- and post-implantation embryonic development and fetal weight loss, both in vitro and in vivo. CTN-induced damage processes directly promoted reactive oxygen species (ROS) generation, loss of mitochondrial membrane potential (MMP) and activation of caspase-9 and caspase-3, which were effectively blocked by LQ. Moreover, in an animal model, intravenous injection of dams with CTN (3 mg/kg/day) triggered apoptosis of blastocysts, disruption of embryonic development from the zygote to the blastocyst stage and a decrease in fetal weight. Pre-injection with LQ (5 mg/kg/day) effectively reduced apoptosis and impaired the cytotoxic effects of CTN on development. Our in vivo findings further confirm that CTN exposure via injection has the potential to impair pre- and post-implantation development, leading to apoptosis and the suppression of sequent embryonic development, which can be effectively prevented by LQ.
