Liposomal silymarin anti-oxidative and anti-apoptotic features in lung cells: An implication in cadmium toxicity. J Trace Elem Med Biol 2023; 80:127291. [PMID: 37672872 DOI: 10.1016/j.jtemb.2023.127291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 07/25/2023] [Accepted: 08/21/2023] [Indexed: 09/08/2023]
Abstract
BACKGROUND Several metallic elements with high atomic weight and density are serious systemic toxicants, and their wide environmental distribution increase the risk of their exposure to human. Silymarin (SL), a polyphenol from milk thistle (Silybum marianum) plant has shown protective role against heavy metal toxicity. However, its low aqueous solubility and rapid metabolism limits its therapeutic potential in clinic. METHODS We compared the role of silymarin nanoliposomes (SL-L) against cadmium (Cd) toxicity in normal MRC-5 and A 549 cancer cells. MRC-5 and A 549 cells exposed to Cd at 25 and 0.25 µM respectively, were treated with various non-toxic SL-L concentrations (2.5, 5, 10 µM) and cells viability, reactive oxygen species (ROS) generation, apoptosis and levels of cleaved PARP and caspase-3 proteins were determined following incubation. RESULTS Results indicated that Cd exposure significantly increased apoptosis due to ROS generation, and showed greater toxicity on cancer cells compared to normal cells. While SL-L at higher concentrations (25 µM and higher) exhibits pro-apoptotic features, lower concentrations (10 and 2.5 µM for MRC-5 and A 549 cancer cells, respectively) played a protective and anti-oxidant role in Cd induced toxicity in both cells. Further, lower SL-L was required to protect cancer cells against Cd toxicity. In general, treatment with SL-L significantly improved cell survival by decreasing ROS levels, cleaved PARP and caspase-3 in both MRC-5 and A 549 cells compared to free silymarin. CONCLUSION Results demonstrated that SL-L potential in protecting against Cd-induced toxicity depends on concentration-dependent antioxidant and anti-apoptotic balance.

Abstract
Lead (Pb) is a critical industrial and environmental contaminant that can cause pathophysiological changes in several cellular and organ systems and their processes, including cell proliferation, differentiation, apoptosis, and survival. The skin is readily exposed to and damaged by Pb, but the mechanisms through which Pb damages cells are not fully understood. We examined the apoptotic properties of Pb in mouse skin fibroblast (MSF) in vitro. Treatment of fibroblasts with 40, 80, and 160 μM Pb for 24 h revealed morphological alterations, DNA damage, enhanced caspase-3, -8, and -9 activities, and apoptotic cell population. Furthermore, apoptosis was dosage (0-160 μM) and time (12-48 h) dependent. Concentrations of intracellular calcium (Ca2+) and reactive oxygen species were increased, and the mitochondrial membrane potential was decreased in exposed cells. Cell cycle arrest was evident at the G0/G1 phase. The Bax, Fas, caspase-3 and -8, and p53 transcript levels were increased, whereas Bcl-2 gene expression was decreased. Based on our analysis, Pb triggers MSF apoptosis bydisrupting intracellular homeostasis. Our findings enrich the knowledge about the mechanistic function of Pb-induced cytotoxicity on human skin fibroblasts and could potentially guide future Pb health risk assessments.

Silymarin Protects against Acute Liver Injury Induced by Acetaminophen by Downregulating the Expression and Activity of the CYP2E1 Enzyme. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27248855. [PMID: 36557984 PMCID: PMC9784215 DOI: 10.3390/molecules27248855] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 12/03/2022] [Accepted: 12/10/2022] [Indexed: 12/15/2022]
Abstract
Previous studies have shown that silymarin protects against various types of drug-induced liver injury, but whether the protective mechanism of silymarin against acetaminophen-induced liver injury is related to the CYP2E1 enzyme remains unclear. In this study, we investigated the effect of silymarin on the activity and expression of CYP2E1 in vitro and in vivo. The results of in vitro studies showed that silymarin not only inhibited the activity of CYP2E1 in human and rat liver microsomes but also reduced the expression of CYP2E1 in HepG2 cells. In vivo studies showed that silymarin pretreatment significantly reduced the conversion of chlorzoxazone to its metabolite 6-OH-CLX and significantly increased the t1/2, area under the curve (AUC) and mean residence time (MRT) of chlorzoxazone. In addition, silymarin pretreatment significantly inhibited the upregulation of Cyp2e1 expression, reduced the production of 3-cysteinylacetaminophen trifluoroacetic acid salt (APAP-CYS), and restored the liver glutathione level. The results of our study show that silymarin plays an important protective role in the early stage of acetaminophen-induced acute liver injury by reducing the activity and expression of CYP2E1, reducing the generation of toxic metabolites, and alleviating liver injury.

Abstract
A new chiral molecularly imprinted polymer (MIP) sensor with dual recognition ability was developed for the highly selective separation of enantiomers with toxic side effects in drugs. The sensor contains double-stranded deoxyribonucleic acid (dsDNA) as the element that immobilizes the chiral molecular conformation: the dsDNA enables the imprinted cavities to match the three-dimensional structure and functional groups from the chiral molecule. By embedding the spatial orientation of dsDNA in MIPs, one can accurately capture and immobilize the molecular conformation, eliminating the influence of interfering analogues. Herein, L-penicillamine (L-Pen) was selected as the chiral template molecule and embedded into dsDNA to form dsDNA-L-Pen complex, which was then embedded into the MIPs by electropolymerization. After elution, the stereo-selective imprinted cavities were obtained. The ATATATATATAT-TATATATATATA base sequence showed a high affinity for the embedded L-Pen, which endowed the imprinted cavities with a larger number of sites and improved the selectivity toward Pen enantiomers. Under the optimal working conditions, the current response of the MIP/dsDNA sensor exhibited a positive linear relationship with the logarithm of the L-Pen concentration in the range of 3.0 × 10-16 to 3.0 × 10-13 mol/L, and the detection limit was 2.48 × 10-16 mol/L. After the introduction of dsDNA into the MIP, the selectivity of the sensor toward D-Pen increased by 6.4 times, and the sensor was successfully applied in the analysis of L-Pen in penicillamine tablets.

Abstract
Lead (Pb) is an environmental neurotoxin that can lead to toxicity. It has shown that tissues can be exposed to oxidative stress in lead poisoning. Since silymarin is a natural agent with antioxidant effects, this study aimed to investigate the antioxidant and chelation effects of silibinin and nano-silibinin on the oxidative stress status in lead-poisoned rats. Sixty male Wistar rats randomly divided into ten groups (n = 6). Control and Pb groups treated with or without silibinin and nano-silibinin for six days. Following measuring of weight and blood lead levels, biochemical antioxidant parameters evaluated. Finally, a histopathological examination of the liver performed. In this experiment, silibinin and more efficiently nano-silibinin prevented weight loss and blood lead level elevation induced by lead. Also, they increased the attenuated levels of superoxide dismutase (SOD) activity, catalase (CAT), total thiol molecules (TTM), glutathione (GSH), and total antioxidant capacity (TAC). Lead-induced elevation of lipid peroxidation products (MDA) and nitric oxide (NO) normalized to the standard level in silibinin and especially nano-silibinin groups. These data suggested that silibinin and especially nano-silibinin can decrease blood lead levels and prevent weight loss and oxidative stress in the lead-poisoned rat's model.

Abstract
BACKGROUND Liver fibrosis is a chronic wound-healing response to liver injury of various origins and represents a major health problem. OBJECTIVE The current study endeavored to investigate the repressing effect of fisetin on hepatic fibrosis induced by thioacetamide (TAA) in rats. MATERIALS AND METHODS Rats were injected with TAA (200 mg/kg) intraperitoneally twice per week for 6 weeks to induce liver fibrosis. Fisetin (50 and 100 mg/kg/day) or silymarin (50 mg/kg/day) were given orally on a daily basis along with TAA. Liver function parameters, oxidative stress, inflammatory and fibrogenic biomarkers as well as wnt3a, β-catenin, glycogen synthase kinase 3 (GSK-3β) and cyclin D1 were estimated. Histoapthological and immunohistochemical examinations were performed. RESULTS Fisetin restored normal liver functions, increased reduced glutathione (GSH) level and decreased malondialdehyde (MDA), as well as inflammatory biomarkers including; tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6). Additionally, it lessened transforming growth factor β1 (TGF-β1), collagen I and tissue inhibitor of metalloproteinase-1 (TIMP-1) levels as well as elevated matrix metalloproteinase-9 (MMP-9) hepatic content. Furthermore, fisetin significantly suppressed wnt3a gene expression associated with decreased β-catenin and increased GSK-3β levels. Moreover, fisetin decreased the progress of histologic hepatic fibroplasia and diminished hepatic expression of α-SMA and cyclin D1. CONCLUSION Fisetin curbed liver fibrosis and exhibited superior activity over silymarin through inhibition of hepatic stellate cells (HSCs) activation and proliferation via suppressing the Wnt/β-catenin pathway, modulating MMP-9 and TIMP-1, and inhibiting multiple profibrogenic factors, besides its antioxidant and anti-inflammatory effects. Therefore, fisetin is a promising therapeutic candidate for hepatic fibrosis.

Abstract
PURPOSE Lead Poisoning is a major health problem in Iran. We aimed to compare efficacy of a standard regimen (Succimer) with that of a low-priced combination of D-penicillamine and Garlic in outpatients with lead poisoning. METHODS In this retrospective cross-sectional study, year-long clinical files of outpatients with lead poisoning in two referral toxicology clinics in Mashhad, Iran were reviewed. A total of 79 patients (all men), received either Succimer or a combination of D-penicillamen plus garlic (DPN + Gar), for 19 and 30 days, respectively. Clinical and laboratory data, including blood lead level (BLL), were analyzed and treatment expanses were compared between the two regimens. RESULTS Of 79 male patients, 42 were treated by DPN + Gar and 37 received Succimer. Mean BLL of DPN + Gar group before treatment (965.73 ± 62.54 µg/L) was higher than that of the Succimer group (827.59 ± 24.41) (p < 0.001). After treatment, BLL in both groups significantly reduced to 365.52 ± 27.61 µg/L and 337.44 ± 26.34 µg/L, respectively (p < 0.001). The price of a 19-day treatment with Succimer was approximately 28.6 times higher than a one-month course of treatment with garlic plus DPN. None of the treatments caused serious side effects in the patients. CONCLUSION Combination therapy with DPN + Gar is as effective as Succimer in Pb poisoning, while treatment with Succimer is significantly more expensive.

Abstract
BACKGROUND Taraxacum officinale (TO) or dandelion has been frequently used to prevent or treat different liver diseases because of its rich composition in phytochemicals with demonstrated effect against hepatic injuries. This study aimed to investigate the possible preventing effect of ethanolic TO root extract (TOERE) on a rat experimental acute on chronic liver failure (ACLF) model. METHODS Chronic liver failure (CLF) was induced by human serum albumin, and ACLF was induced in CLF by D-galactosamine and lipopolysaccharide (D-Gal-LPS). Five groups (n = 5) of male Wistar rats (200-250 g) were used: ACLF, ACLF-silymarin (200 mg/kg b.w./day), three ACLF-TO administered in three doses (200 mg, 100 mg, 50 mg/kg b.w./day). RESULTS The in vivo results showed that treatment with TOERE administered in three chosen doses before ACLF induction reduced serum liver injury markers (AST, ALT, ALP, GGT, total bilirubin), renal tests (creatinine, urea), and oxidative stress tests (TOS, OSI, MDA, NO, 3NT). Histopathologically, TOERE diminished the level of liver tissue injury and 3NT immunoexpression. CONCLUSIONS This paper indicated oxidative stress reduction as possible mechanisms for the hepatoprotective effect of TOERE in ACLF and provided evidence for the preventive treatment.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Silybum marianum (L.) Gaertn. or Milk thistle is a medicinal plant native to Northern Africa, Southern Europe, Southern Russia and Anatolia. It also grows in South Australia, North and South America. In traditional knowledge, people have used S. marianum for liver disorders such as hepatitis, liver cirrhosis and gallbladder diseases. The main active compound of the plant seeds is silymarin, which is the most commonly used herbal supplement in the United States for liver problems. Nowadays, S. marianum products are available as capsules, powders, and extracts. AIM OF STUDY The aim of our study is to draw a more comprehensive overview of the traditional heritage, pharmacological benefits and chemical fingerprint of S. marianum extracts and metabolites; as well as their metabolism and bioavailability. MATERIALS AND METHODS An extensive literature search has been conducted using relavant keywords and papers with rationale methodology and robust data were selected and discussed. Studies involving S. marianum or its main active ingredients with regards to hepatoprotective, antidiabetic, cardiovascular protection, anticancer and antimicrobial activities as well as the clinical trials performed on the plant, were discussed here. RESULTS S. marianum was subjected to thousands of ethnopharmacological, experimental and clinical investigations. Although, the plant is available for use as a dietary supplement, the FDA did not yet approve its use for cancer therapy. Nowadays, clinical investigations are in progress where a global evidence of its real efficiency is needed. CONCLUSION S. marianum is a worldwide used herb with unlimited number of investigations focusing on its benefits and properties, however, little is known about its clinical efficiency. Moreover, few studies have discussed its metabolism, pharmacokinetics and bioavailability, so that all future studies on S. marianum should focus on such areas.

Abstract
Shoumei is a kind of white tea (slightly fermented Camellia sinensis) that is rich in polyphenols. In this study, polyphenols were extracted from Shoumei. High-performance liquid chromatography (HPLC) showed that the polyphenols included mainly gallic acid, catechin, hyperoside, and sulfuretin. In an in vitro experiment, H2O2 was used to induce oxidative damage in human normal hepatic L-02 cells. In an animal experiment, CCl4 was used to induce liver injury. The in vitro results showed that Shoumei polyphenols inhibited oxidative damage in normal hepatic L-02 cells, and the in vivo results showed that the polyphenols effectively reduced liver index values in mice with liver injury. The polyphenols also decreased aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), triglyceride (TG), total cholesterol (TC), blood urea nitrogen (BUN), nitric oxide (NO), malondialdehyde (MDA), interleukin 6 (IL-6), interleukin 12 (IL-12), tumour necrosis factor alpha (TNF-α), and interferon gamma (IFN-γ) levels and increased albumin (ALB), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) levels in the serum of mice with liver injury. Furthermore, pathological observation showed that the Shoumei polyphenols reduced CCl4-induced hepatocyte damage. qRT-PCR and Western blotting showed that the polyphenols upregulated the mRNA and protein expression of neuronal nitric oxide synthase (nNOS), endothelial nitric oxide synthase (eNOS), manganese- (Mn-) SOD, copper/zinc- (Cu/Zn-) SOD, CAT, and inhibitor of nuclear factor kappa B (NF-κB) alpha (IκB-α) and downregulated the expression of inducible nitric oxide synthase (iNOS) and NF-κB p65. The Shoumei polyphenols had a preventive effect against CCl4-induced mouse liver injury equivalent to that of silymarin. The four polyphenols identified as the key substances responsible for this effect mediated the effect through their antioxidant capacity. These results suggest that Shoumei polyphenols are high-quality natural products with liver-protective effects.

Hao L, Liu MW, Gu ST, Huang X, Deng H, Wang X. Sedum sarmentosum Bunge extract ameliorates lipopolysaccharide- and D-galactosamine-induced acute liver injury by attenuating the hedgehog signaling pathway via regulation of miR-124 expression. BMC Complement Med Ther 2020; 20:88. [PMID: 32178661 PMCID: PMC7076998 DOI: 10.1186/s12906-020-2873-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2019] [Accepted: 02/27/2020] [Indexed: 12/12/2022] Open
Abstract
Background Sedum sarmentosum is traditionally used to treat various inflammatory diseases in China. It has protective effects against acute liver injury, but the exact mechanism of such effects remains unclear. This study investigated the protective effects of S. sarmentosum extract on lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-induced acute liver injury in mice and the mechanism of such effects. Methods Mice were randomly divided into control, treatment, model, and model treatment groups. Acute liver injury was induced in model mice via intraperitoneal injection of LPS and D-GalN with doses of 10 μg/kg of LPS and 500 mg/kg, respectively. The mRNA expression levels of miR-124, Hedgehog, Patched (Ptch), Smoothened (Smo), and glioma-associated oncogene homolog (Gli) in liver tissues were determined through RT-PCR, and the protein levels of Hedgehog, Ptch, Smo, Gli, P13k, Akt, HMGB1, TLR4, IkB-α, p-IkB-α, and NF-kB65 were evaluated via Western blot analysis. The serum levels of IL-6, TNF-α, CRP, IL-12, and ICAM-1 were determined via ELISA. TLR4 and NF-κBp65 activity and the levels of DNA-bound NF-KB65 and TLR4 in LPS/D-GalN-induced liver tissues were also determined. We recorded the time of death, plotted the survival curve, and calculated the liver index. We then observed the pathological changes in liver tissue and detected the levels of liver enzymes (alanine aminotransferase [ALT] and aspartate transaminase [AST]) in the serum and myeloperoxidase (MPO) and plasma inflammatory factors in the liver homogenate. Afterward, we evaluated the protective effects of S. sarmentosum extracts on acute liver injury in mice. Results Results showed that after S. sarmentosum extract was administered, the expression level of miR-124 increased in liver tissues. However, the protein expression levels of Hedgehog, Ptch, Smo, Gli, P13k, p-Akt, HMGB1, TLR4, p-IκB-α, and NF-κB65 and the mRNA expression levels of Hedgehog, Ptch, Smo, and Gli decreased. The MPO level in the liver, the IL-6, TNF-α, CRP, IL-12, and MMP-9 levels in the plasma, and the serum ALT and AST levels also decreased, thereby reducing LPS/D-GalN-induced liver injury and improving the survival rate of liver-damaged animals within 24 h. Conclusions S. sarmentosum extract can alleviate LPS/D-GalN-induced acute liver injury in mice and improve the survival rate of mice. The mechanism may be related to the increase in miR-124 expression, decrease in Hedgehog and HMGB1 signaling pathway activities, and reduction in inflammatory responses in the liver. Hedgehog is a regulatory target for miR-124.

LncRNA Uc.173 is a key molecule for the regulation of lead-induced renal tubular epithelial cell apoptosis. Biomed Pharmacother 2018; 100:101-107. [PMID: 29425744 DOI: 10.1016/j.biopha.2018.01.112] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2017] [Revised: 01/21/2018] [Accepted: 01/24/2018] [Indexed: 01/28/2023] Open
Abstract
Transcribed ultra-conserved region (T-UCR) transcripts are a novel class of long non-coding RNAs (lncRNAs) transcribed from ultra-conserved region which is highly conserved in human, rat, and mouse genome. LncRNA UC.173 has been found significantly down-regulated in lead-exposed population and lead-exposed animal mode, and had an inhibitory effect on lead-induced nerve cell apoptosis. We supposed that lncRNA UC.173 had an inhibitory effect on lead-induced renal tubular epithelial cell apoptosis. Thus, the aim of our study was to explore the function of lncRNA UC.173 in lead-exposed renal tubular epithelial cells. In our results, lead exposure inhibited renal tubular epithelial cells viability and promoted cell apoptosis and apoptosis-associated genes expression, but no effect on cell-cycle distribution. Lead exposure inhibited the expression of lncRNA UC.173 in renal tubular epithelial cells, and the inhibition effect was time-dependent and concentration-dependent. Up-regulation of lncRNA UC.173 had no effect on renal tubular epithelial cell viability, cell cycle and apoptosis, but significantly rescued lead-induced inhibition of renal tubular epithelial cell viability and suppressed lead-induced cell apoptosis. In summary, our experiments suggest that lncRNA UC.173 is certainly involved in the regulation of lead-induced renal tubular epithelial cell apoptosis, which may supply a new strategy to minimize lead-induced nephrotoxicity.
