Abstract
BACKGROUD The interactions between Chinese herbs and drugs pose a great challenge to the combined clinical application of Chinese herbs and drugs. Chinese medicinal products contain complex pharmacologically active components that may influence the in vivo processes of drugs in a variety of ways. In China, drugs based on Panax ginseng total saponins (PNS) are often combined with warfarin for the treatment of cardiovascular diseases. OBJECTIVES To assess the effects of Panax notoginseng saponins (PNS) on the pharmacokinetics of warfarin and its mechanism. METHOD Blood was collected for the determination of the prothrombin time (PT) and international normalized ratio (INR) from rats treated with warfarin alone or with warfarin + PNS. The plasma concentration of warfarin was determined by high-performance liquid chromatography. Western blot was used to detect the expression of cytochrome P450 (CYP) enzymes. RESULTS When warfarin and PNS were co-administered, the PT and INR increased compared to when warfarin was given alone. 72 hours after administration, compared to the warfarin alone group, the warfarin + low-dose PNS, warfarin + medium-dose PNS, and warfarin + high-dose PNS groups showed 110%, 122%, and 126% increases in PT, respectively (all P < 0.05), as well as 111%, 124%, and 128% increases in INR (all P < 0.05). Compared with the warfarin alone group, the clearance rate (CL/F) of warfarin in the warfarin + low-dose PNS, warfarin + medium-dose PNS, and warfarin + high-dose PNS groups was 10% (P > 0.05), 23% (P < 0.05), and 33% (P < 0.05) lower, respectively, while the systemic exposure (area under the concentration-time curve, AUC0-t) increased by 106% (P > 0.05), 119% (P < 0.05), and 134% (P < 0.05), respectively, and the blood concentration of warfarin incresed by 112%, 113%, and 114%, respectively (all P > 0.05). After combined treatment of HepG2 cells with warfarin + PNS, CYP1A2 expression was upregulated (P < 0.05) and CYP3A4 was downregulated (P < 0.05) but there was no effect on CYP2C9. In animal experiments, PNS had different effect on the expression of CYP1A2 in different doses. While a low dose of PNS resulted in downregulated CYP1A2 expression (P < 0.05), a medium dose resulted in upregulation (P < 0.05), and CYP1A2 expression was not significantly affected by a high dose of PNS (P > 0.05). Meanwhile, PNS at all doses downregulated the expression of CYP3A4 (P < 0.05) but had no effect on the expression of CYP2C9 (P > 0.05). CONCLUSION PNS can increase the blood concentration of warfarin, as well as the exposure time, and it can enhance the anticoagulant effect of warfarin by inhibiting the expression of the liver enzyme CYP3A4.

Abstract
Infertility is an emerging health issue worldwide, and female infertility is intimately associated with embryo implantation failure. Embryo implantation is an essential process during the initiation of prenatal development. Recent studies have strongly suggested that autophagy in the endometrium is the most important factor for successful embryo implantation. In addition, several studies have reported the effects of various natural products on infertility improvement via the regulation of embryo implantation, embryo quality, and endometrial receptivity. However, it is unclear whether natural products can improve embryo implantation ability by regulating endometrial autophagy. Therefore, we performed a literature review of studies on endometrial autophagy, embryo implantation, natural products, and female infertility. Based on the information from these studies, this review suggests a new treatment strategy for female infertility by proposing natural products that have been proven to be safe and effective as endometrial autophagy regulators; additionally, we provide a comprehensive understanding of the relationship between the regulation of endometrial autophagy by natural products and female infertility, with an emphasis on embryo implantation.

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.

Mol Med Rep 2021; 23:291. [PMID: 33649817 PMCID: PMC7930927 DOI: 10.3892/mmr.2021.11931] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 12/10/2020] [Indexed: 12/21/2022] Open
Abstract
Ginsenoside Rg1 (Rg1) is traditional Chinese medicine with neuroprotective activity. Previous studies have demonstrated that Rg1 improves Alzheimer's disease (AD) and alters gut microbiology, but its mechanism remains to be elucidated, and thus far, its use in the treatment of AD has not been satisfactory. The present study investigated the improvement effects of Rg1 and its association with the microbiota of the large intestine. Following treatment with Rg1 in AD tree shrews, the treatment group demonstrated significantly shorter escape latency and crossed a platform more frequently in a water maze test. Western blotting demonstrated that Rg1 inhibited the expression of β-secretase 1, while increasing microtubule-associated protein 2 and Fox-3 in the hippocampus. Immunohistochemical analysis revealed that Rg1 decreased the expression of amyloid β, tau phosphorylated at serine 404 and pro-apoptotic factor Bax, while increasing the expression of Bcl-2 in the hippocampus and cortex. High throughput sequencing of 16S rRNA demonstrated that Rg1 altered the microbiota abundance of the large intestine. In conclusion, Rg1 affected the expression of apoptosis proteins, possessed a neuroprotective effect and may have a close association with the microbiota of large intestine by significantly reducing the abundance of Bacteroidetes and increasing the energy requirement of tree shrews.

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
ETHNOPHARMACOLOGICAL RELEVANCE Panax notoginseng (Burk.) F. H. Chen, also called Sanqi, is a widely used traditional Chinese medicine, which has long history used as herbal medicines. It is currently an important medicinal material in China, holding the first place in the sale volume of the whole patent medicines market in China, and the market size of the single species has exceeded 10 billion yuan. In addition, P. notoginseng is an important constituent part of many famous Chinese patent medicines, such as Compound Danshen Dripping Pills and Yunnan Baiyao. P. notoginseng saponins (PNSs), which are the major active components of P. notoginseng, are a kind of chemical mixture containing different dammarane-type saponins. Many studies show that PNSs have been extensively used in medical research or applications, such as atherosclerosis, diabetes, acute lung injury, cancer, and cardiovascular diseases. In addition, various PNS preparations, such as injections and capsules, have been made commercially available and are widely applied in clinical practice. AIM OF THE REVIEW Since the safety and efficacy of compounds are related to their qualitative and quantitative analyses, this review briefly summarizes the analytic approaches for PNSs and their biological effects developed in the last decade. METHODOLOGY This review conducted a systematic search in electronic databases, such as Pubmed, Google Scholar, SciFinder, ISI Web of Science, and CNKI, since 2009. The information provided in this review is based on peer-reviewed papers and patents in either English or Chinese. RESULTS At present, the chromatographic technique remains the most extensively used approach for the identification or quantitation of PNSs, coupled with different detectors, among which the difference mainly lies in their sensitivity and specificity for analyzing various compounds. It is well-known that PNSs have traditionally strong activity on cardiovascular diseases, such as atherosclerosis, intracerebral hemorrhage, or brain injury. The recent studies showed that PNSs also responded to osteoporosis, cancers, diabetes, and drug toxicity. However, some other studies also showed that some PNSs injections and special PNS components might lead to some biological toxicity under certain dosages. CONCLUSION This review may be used as a basis for further research in the field of quantitative and qualitative analyses, and is expected to provide updated and valuable insights into the potential medicinal applications of PNSs.

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.

Less SO 2 residue may not indicate higher quality, better efficacy and weaker toxicity of sulfur-fumigated herbs: Ginseng, a pilot study. JOURNAL OF HAZARDOUS MATERIALS 2019; 364:376-387. [PMID: 30384248 DOI: 10.1016/j.jhazmat.2018.10.038] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/10/2018] [Revised: 09/21/2018] [Accepted: 10/12/2018] [Indexed: 06/08/2023]
Abstract
Sulfur dioxide (SO2) is a hazardous residue in sulfur-fumigated herbs. Standards limiting SO2 content have been adopted worldwide for quality control of sulfur-fumigated herbs, and herbs with less SO2 are believed to be better. However, the standards are based only on the safe dose of SO2 and may not characterize changes in herbal quality, thereby the efficacy and toxicity, resulting from sulfur fumigation. To confirm this, here the correlation of residual SO2 content with the quality/efficacy/toxicity of sulfur-fumigated herb was investigated, and ginseng was selected as a pilot study object. Four sulfur-fumigated ginseng samples with different SO2 contents were systemically compared regarding their quality, anti-inflammatory, anti-shock and anti-stress efficacies, as well as acute and chronic toxicities. The results demonstrated that the SO2 content did not correlate with the quality, efficacy and toxicity changes of ginseng; more specifically, less SO2 residue did not indicate higher quality, better efficacy nor weaker toxicity. This fact suggests that SO2 content cannot characterize the variations in quality, efficacy and toxicity of sulfur-fumigated herbs. Therefore, the standard limiting SO2 content alone may be inadequate for quality control of sulfur-fumigated herbs, and new standards including other indicators that can exactly reflect herbal efficacy and safety are necessary.

ENVIRONMENTAL TOXICOLOGY 2019; 34:48-59. [PMID: 30259633 DOI: 10.1002/tox.22656] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/07/2018] [Revised: 08/17/2018] [Accepted: 08/18/2018] [Indexed: 06/08/2023]
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.

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.

Protective Effects of Ginsenoside Rb1 against Blood-Brain Barrier Damage Induced by Human Immunodeficiency Virus-1 Tat Protein and Methamphetamine in Sprague-Dawley Rats.

Abstract
Although antiretroviral therapy has helped to improve the lives of individuals infected with human immunodeficiency virus 1 (HIV-1), these patients are often still afflicted with HIV-1-associated neurocognitive disorders, which can lead to neurocognitive impairment and even dementia, and continue to hamper their quality of life. Methamphetamine abuse in HIV-1 patients poses a potential risk for HIV-associated neurocognitive disorders, because methamphetamine and HIV-1 proteins such as transactivator of transcription can synergistically damage the blood-brain barrier (BBB). In this study, we aimed to examine the effects of methamphetamine and HIV-1 Tat protein on the blood-brain barrier function and to determine whether ginsenoside Rb1 (GsRb1) plays a role in protecting the BBB. Sprague-Dawley rats were divided into four groups. The experimental groups received methamphetamine and HIV-1 Tat protein or both and the control group received saline or GsRb1 pretreatment. Oxidative stress-related factors, tight junction (TJ) proteins, blood-brain barrier permeability, and morphological changes were recorded in each group. The results showed that the group treated with Methamphetamine[Formula: see text]Tat showed a significant change at the ultrastructural level and in the levels of oxidative stress-related factors, TJ proteins, and BBB permeability, suggesting that the BBB function was severely damaged by HIV-1 Tat and methamphetamine synergistically. However, malondialdehyde levels and BBB permeability were lower and the oxidative stress-related factors superoxide dismutase and glutathione were higher in the GsRb1-treated group than in the Methamphetamine[Formula: see text]Tat-treated group, indicating that GsRb1 can protect the BBB against the toxic effects of HIV-1 Tat and methamphetamine. These results show that GsRb1 may offer a potential therapeutic option for patients with HIV-associated neurocognitive disorders or other neurodegenerative diseases.

[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.

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.

Abstract
BACKGROUND AND ETHNOPHARMACOLOGICAL RELEVANCE Ginseng has been used as efficient tonic and for the treatment of various diseases including hepatic disorders. Ginseng saponins, also known as ginsenosides, are principal constituents and have been treated to be responsible for disparate ginseng health benefits. The current review mainly focuses on ginsenoside Rg1, a compound isolated from traditional Chinese herbal medicine Panax ginseng Meyer. AIMS To summary the hepataprotective effects and related mechanisms of ginsenoside Rg1, we conclude this review by combining the literature and our own researches. METHODS As evidenced, we organized the pharmacological function of ginsenoside Rg1 by searching the pubmed. It has been deeply studied and summarized in the field of neurobiology, however, in this paper we described the pharmacological function of Rg1 in liver related to antioxidative stress and anti-inflammation. R&D: Individual ginsenoside could be used since it shows a wide array of beneficial functions in the regulation and disorders of acute and chronic hepatotoxicity, hepatitis, hepatic fibrosis and cirrhosis in various pathways and different mechanisms. Of note, the antioxidant hepatic protection of ginsenoside Rg1 is mainly through the induction of Keap1-Nrf2-ARE signaling pathway. CONCLUSION The multi-target actions of Rg1 substantiates it as a promising drug candidate for the treatment of hepatic impairment in different factors induced liver diseases.
