Xie W, Chen HG, Chen RH, Zhao C, Gong XJ, Zhou X. Intervention effect of Lycium barbarum polysaccharide on lead-induced kidney injury mice and its mechanism: A study based on the PI3K/Akt/mTOR signaling pathway. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117197. [PMID: 37722516 DOI: 10.1016/j.jep.2023.117197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 05/22/2023] [Accepted: 09/14/2023] [Indexed: 09/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The traditional medicinal application of Lycium barbarum is centered on the improvement of eyesight, as well as the nourishment of liver and kidney functions. Lycium barbarum polysaccharide (LBP), serving as the principal active constituent of Lycium barbarum, has been identified as the main contributor to these beneficial effects. Previous studies have indicated that Lycium barbarum polysaccharide exhibits a renoprotective effect against lead-induced injury, but its mechanism and efficacy remain unclear. AIM OF THE STUDY The objective of this study was to examine the effectiveness of LBP in preventing lead-induced renal injury and investigate both the toxic mechanism of lead-induced renal injury and the efficacy mechanism of LBP against it, with a focus on the PI3K/AKT/mTOR signaling pathway. MATERIALS AND METHODS The drug effect and mechanism of LBP on lead-induced kidney injury were investigated by administering positive drugs and LBP to mice with established lead-induced kidney injury. RESULTS The renal function of mice with lead-induced renal injury was significantly restored, renal tissue lesions and renal mitochondrial damage were delayed, a disorder of hematological parameters induced by lead was improved, the increase of lead-induced renal index was reduced, and the body weight of mice with lead-induced renal injury was increased by the LBP intervention, as revealed by the results of pharmacodynamic experiments. Based on PI3K /AKT /mTOR signaling pathway, the toxic mechanism of lead-induced kidney injury and the pharmacodynamic mechanism of LBP against lead-induced kidney injury were studied. The results showed that lead could activate the TLR4 receptor, and then activate PI3K /AKT /mTOR signaling pathway, inhibit autophagy of kidney tissue cells, and enhance apoptosis of kidney tissue cells to induce kidney injury; LBP inhibits the activation of TLR4 receptor, which in turn inhibits the PI3K/AKT/mTOR signaling pathway, enhances the autophagy of kidney tissue cells, reduces the apoptosis of kidney tissues, and delays lead-induced kidney injury.

Qin X, Wang X, Xu K, Yang X, Wang Q, Liu C, Wang X, Guo X, Sun J, Li L, Li S. Synergistic antitumor effects of polysaccharides and anthocyanins from
Lycium ruthenicum
Murr. on human colorectal carcinoma LoVo cells and the molecular mechanism. Food Sci Nutr 2022; 10:2956-2968. [PMID: 36171788 PMCID: PMC9469862 DOI: 10.1002/fsn3.2892] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 03/15/2022] [Accepted: 04/05/2022] [Indexed: 11/11/2022] Open
Abstract
The antitumor effects of Lycium ruthenicum Murr. polysaccharides (LRPS) and Lycium ruthenicum Murr. anthocyanins (LRAC) were comprehensively investigated in this study. LPRS was obtained by water extraction and alcohol precipitation and further purified using diethylaminoethyl cellulose (DEAE‐Cellulose) and Sephadex G‐75 columns. High‐performance liquid chromatography (HPLC) and Fourier transform‐infrared (FT‐IR) spectroscopy were used to characterize the purified LRPS. The results showed that the purified LRPS contained heteropolysaccharides, mainly composed of arabinose, galactose, and glucose with weight percentage of 41.2%, 33.6%, and 10.8%, respectively. More importantly, LRPS (500 μg/ml) and LRAC (80 μg/ml) failed to impede the proliferation of tumor cells when applied solely (48 h incubation), yet remarkable antineoplastic effects were found once they were applied altogether, since the LoVo cells, a typical human colorectal carcinoma cell line, were significantly inhibited by the mixture of LRPS (150 μg/ml) and LRAC (20 μg/ml) (LRPS&AC) in 24 h. The antineoplastic activity resulted from the combination of both LRPS and LRAC (LRPS&AC), by means of blocking the cell cycle at the G0–G1 phase and inducing LoVo cell apoptosis via reactive oxygen species (ROS)‐dependent pathway. The inhibitory effects of LRPS&AC were specific to the tumor cells, without imposing on the proliferation of normal cells. Western blotting revealed that the antitumor effect was related to the mitochondria‐mediated apoptosis launched by the cross‐action of PI3K/Akt (phosphatidylinositol 3‐kinase/protein kinase B) and JAK2/STAT3 (janus kinase 2/signal transduction and activator of transcription 3) signaling pathways. These findings for the first time reveal the synergistic antitumor effects of LRPS&AC and the related mechanisms, which enable Lycium ruthenicum Murr. to serve as a natural source to develop therapeutic reagents and functional foods with antineoplastic properties.

Abstract
In the last decades, several nutraceutical substances have received great attention for their potential role in the prevention and treatment of different diseases as well as for their beneficial effects in promoting the health of humans and animals. Goji berries (GBs) are the fruit of Lycium barbarum and other species of Lycium, used in traditional Chinese medicine, and they have recently become very popular in the Occidental world because of their properties, such as anti-aging, antioxidant, anticancer, neuroprotective, cytoprotective, antidiabetic, and anti-inflammatory activities. These effects are essentially evaluated in clinical trials in humans; in experimental animal models, such as mice and rats; and in cell lines in in vitro studies. Only recently has scientific research evaluated the effects of GBs diet supplementation in livestock animals, including rabbits. Although studies in the zootechnical field are still limited and the investigation of the GB mechanisms of action is in an early stage, the results are encouraging. This review includes a survey of the experimental trials that evaluated the effects of the GBs supplementation on reproductive and productive performances, immune system, metabolic homeostasis, and meat quality principally in the rabbit with also some references to other livestock animal species. Evidence supports the idea that GB supplementation could be used in rabbit breeding, although future studies should be conducted to establish the optimal dose to be administered and to assess the sustainability of the use of GBs in the diet of the rabbit.

Resveratrol and lycium barbarum polysaccharide improve Qinling giant panda (Ailuropoda melanoleuca Qinlingensis) sperm quality during cryopreservation. BMC Vet Res 2022; 18:23. [PMID: 34996430 PMCID: PMC8739993 DOI: 10.1186/s12917-021-03122-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Accepted: 12/20/2021] [Indexed: 11/23/2022] Open
Abstract
Background Semen cryopreservation has become an essential tool for conservation efforts of the giant panda (Ailuropoda melanoleuca); however, it is severely detrimental to sperm quality. Evidence has shown that antioxidants have the potential to reverse cryopreservation-induced damage in sperm. The purpose of this study was to screen effective antioxidants that could retain sperm quality during cryopreservation and to determine the optimal dose. Seven antioxidant groups, including resveratrol (RSV = 50 μM, RSV = 100 μM, RSV = 150 μM), lycium barbarum polysaccharide (LBP = 2 mg/mL, LBP = 4 mg/mL), laminaria japonica polysaccharides (LJP = 1 mg/mL) or combination (LBP = 2 mg/mL, LJP = 1 mg/mL and RSV = 100 μM) were assessed. Results RSV, LBP, LJP, or a combination of RSV, LBP, and LJP added to the freezing medium significantly improved sperm progressive motility, plasma membrane integrity, acrosome integrity, and mitochondrial activity during the cryopreservation process. Furthermore, the activities of glutathione peroxidase and superoxide dismutase were also improved. The levels of reactive oxygen species and malondialdehyde in semen were notably reduced. Hyaluronidase activity and acrosin activity were significantly increased in LBP-treated sperm. However, sperm total motility and DNA integrity were not significantly different between the groups. Conclusions RSV (50 μM) or LBP (2 mg/mL) are the best candidate antioxidants for inclusion in the freezing medium to improve the quality of giant panda spermatozoa during semen cryopreservation.

Abstract
Elevated serum aldosterone promotes arterial hypertension, cardiac hypertrophy, and diastolic dysfunction. However, the effect of elevated aldosterone levels on cardiac mitochondria remains unclear. We used primary cultures of mouse cardiomyocytes to determine whether aldosterone has direct effects on cardiomyocyte mitochondria, and aldosterone-infused mice as a preclinical model to evaluate the impact of aldosterone in vivo. We show that aldosterone suppressed mtDNA copy number and SOD2 expression via the mineralocorticoid receptor (MR)-dependent regulation of NADPH oxidase 2 (NOX2) and generation of reactive oxygen species (ROS) in primary mouse cardiomyocytes. Aldosterone suppressed cardiac mitochondria adenosine triphosphate production, which was rescued by N-acetylcysteine. Aldosterone infusion for 4 weeks in mice suppressed the number of cardiac mitochondria, mtDNA copy number, and SOD2 protein expression. MR blockade by eplerenone or the administration of N-acetylcysteine prevented aldosterone-induced cardiac mitochondrial damage in vivo. Similarly, patients with primary aldosteronism had a lower plasma leukocyte mtDNA copy number. Plasma leukocyte mtDNA copy number was positively correlated with 24-hour urinary aldosterone level and left ventricular mass index. In conclusion, aldosterone suppresses cardiac mitochondria in vivo and directly via MR activation of ROS pathways.

Abstract
Stress during pregnancy is not only detrimental to a woman's own physical and mental health, but can also cause changes in the intrauterine environment and even have an impact on later growth and development, this study was designed to understand the changes of gut microbiota in the maternal and offspring caused by prenatal chronic stress, and to explore the regulatory effect of LBP on gut microbiota, and then to improve the emotional damage caused by prenatal chronic stress in the offspring. A rat model of prenatal chronic stress was made and used LBP to intervene by gavage. Fresh feces of offspring were collected, the concentration of microbial metabolites were tested by ELISA. Illumina MiSeqPE300 sequencing technology was used to determine the sequence of 16S rRNA V3-V4 of microorganisms. On the PND 42, the emotional function of offspring were tested by open-field test (OFT), sucrose preference test (SPT) and tail of suspend test (TST). Results indicated that stress factors increased the plasma corticosterone level of rats during pregnancy and they appeared depressive behaviors. The body weight of offspring during prenatal chronic stress was lower than the control group, and the plasma corticosterone level was increased. Prenatal chronic stress had a significant impact on emotional performance of the offspring on OFT, SPT and TST. Alpha diversity of gut microbiota and microbiota composition in offspring of prenatal chronic stress was attenuated and some relationships existed between these parameters. LBP treatment reduced offspring's plasma corticosterone level and improved their body weight, changed the emotional function, increased the diversity of gut microbiota. Collectively, these findings disclose that prenatal chronic stress not only causes emotional injury on the offspring, but also changes the gut microbiota of the mother and offspring; LBP may regulate the intestinal flora of the mother, then reducing the influence of stress factors on the emotional injury of offspring.

Abstract
Lead is one of the most common heavy metal pollutants in the environment. Prolonged exposure to lead will induce oxidative stress, inflammation, and apoptosis in the kidneys, which in turn causes kidney injury. Lycium barbarum polysaccharide (LBP) is well known for its numerous pharmacological properties. This study aims to explore the efficacy and mechanism of LBP against lead-induced kidney damage in mice. Symptoms of renal injury were induced in mice by using 25 mg/kg lead acetate (PbAc2), and different doses of LBP (200, 400, and 600 mg/kg BW) were orally administrated to PbAc2-treated mice for five weeks. The results of the pharmacodynamics experiment showed that the renal pathological damages, serum creatinine (Cre), blood urea nitrogen (BUN), and kidney index of PbAc2-treated mice could be significantly alleviated by treatment with LBP. Further, LBP treatment significantly increased the weight and feed intake of PbAc2-treated mice. The dose effect results indicated that a medium dose of LBP was superior to high and low doses. The results of mechanistic experiments showed that LBP could attenuate oxidative stress, inflammation, and apoptosis in the kidneys of mice with lead toxicity by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway.

Ni J, Au M, Kong H, Wang X, Wen C. Lycium barbarum polysaccharides in ageing and its potential use for prevention and treatment of osteoarthritis: a systematic review. BMC Complement Med Ther 2021; 21:212. [PMID: 34404395 PMCID: PMC8371808 DOI: 10.1186/s12906-021-03385-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 07/29/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Lycium barbarum polysaccharide (LBP), the most abundant functional component of wolfberry, is considered a potent antioxidant and an anti-ageing substance. This review aims to outline the hallmarks of ageing in the pathogenesis of osteoarthritis (OA), followed by the current understanding of the senolytic effect of LBP and its potential use in the prevention and treatment of OA. This will be discussed through the lens of molecular biology and herbal medicine. METHODS A literature search was performed from inception to March 2020 using following keywords: "Lycium barbarum polysaccharide", "DNA damage", antioxidant, anti-apoptosis, anti-inflammation, anti-ageing, osteoarthritis, chondrocytes, fibroblasts, osteoblasts, osteoclasts, and "bone mesenchymal stem cell". The initial search yielded 2287 papers, from which 35 studies were selected for final analysis after screening for topic relevancy by the authors. RESULTS In literature different in vitro and in vivo ageing models are used to demonstrate LBP's ability to reduce oxidative stress, restore mitochondrial function, mitigate DNA damage, and prevent cellular senescence. All the evidence hints that LBP theoretically attenuates senescent cell accumulation and suppresses the senescence-associated secretory phenotype as observed by the reduction in pro-inflammatory cytokines, like interleukin-1beta, and matrix-degrading enzymes, such as MMP-1 and MMP-13. However, there remains a lack of evidence on the disease-modifying effect of LBP in OA, although its chondroprotective, osteoprotective and anti-inflammatory effects were reported. CONCLUSION Our findings strongly support further investigations into the senolytic effect of LBP in the context of age-related OA.

Patchouli Alcohol Improves the Integrity of the Blood-Spinal Cord Barrier by Inhibiting Endoplasmic Reticulum Stress Through the Akt/CHOP/Caspase-3 Pathway Following Spinal Cord Injury. Front Cell Dev Biol 2021; 9:693533. [PMID: 34368142 PMCID: PMC8339579 DOI: 10.3389/fcell.2021.693533] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Accepted: 06/28/2021] [Indexed: 01/09/2023] Open
Abstract
Spinal cord injury (SCI) is a destructive and complex disorder of the central nervous system (CNS) for which there is no clinical treatment. Blood-spinal cord barrier (BSCB) rupture is a critical event in SCI that aggravates nerve injury. Therefore, maintaining the integrity of the BSCB may be a potential method to treat SCI. Here, we showed that patchouli alcohol (PA) exerts protective effects against SCI. We discovered that PA significantly prevented hyperpermeability of the BSCB by reducing the loss of tight junctions (TJs) and endothelial cells. PA also suppressed endoplasmic reticulum stress and apoptosis in vitro. Furthermore, in a rat model of SCI, PA effectively improved neurological deficits. Overall, these results prove that PA exerts neuroprotective effects by maintaining BSCB integrity and thus be a promising candidate for SCI treatment.

Abstract
In vitro culture of the embryo is a useful method to treat infertility that shows embryo potential for selecting the best one to transfer and successfully implantation. However, embryo development in vitro is affected by oxidative stresses such as reactive oxygen species that may damage embryo development. Antioxidants are molecules found in fruits, vegetables, and fish that play an important role in reducing oxidative processes. In the natural environment, there is a physiological antioxidant system that protects embryos against oxidative damage. This antioxidant system does not exist in vitro. Antioxidants act as free radical scavengers and protect cells or repair damage done by free radicals. Various studies have shown that adding antioxidants into embryo culture medium improves embryo development in vitro. This review article emphasizes different aspects of various antioxidants, including types, functions and mechanisms, on the growth improvement of different species of embryos in vitro.

Abstract
AbstractThe main objective of this study is to obtain some knowledge of cationic and anionic radicals in early embryo implantation in mice. The method used in this study is known as histochemical staining, in which Xylidine ponceau was used at pH 2.5 and toluidine blue was used at pH 4.0. We detected the change in glycosaminoglycans and total proteins in the endometrial stroma during the preimplantation of mice. This study revealed that the distribution patterns of cationic radicals and anionic radicals are similar on days 4 and 5 of pregnancy. However, there was a distinct difference between cationic radicals and anionic radicals on day 8 of pregnancy. The distribution pattern of cationic radicals is more concentrated in the stroma near the conceptus. Laboratory studies on histochemical stain provide more information about early embryo implantation.
