Abstract
A multitude of plant-derived bioactive compounds have shown significant promise in preventing chronic illnesses, with flavonoids constituting a substantial class of naturally occurring polyphenolic compounds. Apigenin, a flavone identified as 4',5,7-trihydroxyflavone, holds immense promise as a preventative agent against chronic illnesses. Despite its extensive research and recognized nutraceutical value, its therapeutic application remains underexplored, necessitating further clinical investigations. This review delves into the biological sources, nutraceutical prospects, chemistry, pharmacological insights, and health benefits of apigenin. Through multifaceted analytical studies, we explore its diverse pharmacological profile and potential therapeutic applications across various health domains. The manuscript comprehensively examines apigenin's role as a neuroprotective , anti-inflammatory compound, and a potent antioxidant agent. Additionally, its efficacy in combating cardiovascular diseases, anti-diabetic properties, and anticancer potential has been discussed. Furthermore, the antimicrobial attributes and the challenges surrounding its bioavailability, particularly from herbal supplements have been addressed. Available in diverse forms including tablets, capsules, solid dispersions, co-crystals, inclusion complexes and nano formulations. Additionally, it is prevalent as a nutraceutical supplement in herbal formulations. While strides have been made in overcoming pharmacokinetic hurdles, further research into apigenin's clinical effectiveness and bioavailability from herbal supplements remains imperative for its widespread utilization in preventive medicine.

COVID-19-Associated Sepsis: Potential Role of Phytochemicals as Functional Foods and Nutraceuticals. Int J Mol Sci 2024; 25:8481. [PMID: 39126050 PMCID: PMC11312872 DOI: 10.3390/ijms25158481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2024] [Revised: 07/30/2024] [Accepted: 08/01/2024] [Indexed: 08/12/2024] Open
Abstract
The acute manifestations of coronavirus disease 2019 (COVID-19) exhibit the hallmarks of sepsis-associated complications that reflect multiple organ failure. The inflammatory cytokine storm accompanied by an imbalance in the pro-inflammatory and anti-inflammatory host response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection leads to severe and critical septic shock. The sepsis signature in severely afflicted COVID-19 patients includes cellular reprogramming and organ dysfunction that leads to high mortality rates, emphasizing the importance of improved clinical care and advanced therapeutic interventions for sepsis associated with COVID-19. Phytochemicals of functional foods and nutraceutical importance have an incredible impact on the healthcare system, which includes the prevention and/or treatment of chronic diseases. Hence, in the present review, we aim to explore the pathogenesis of sepsis associated with COVID-19 that disrupts the physiological homeostasis of the body, resulting in severe organ damage. Furthermore, we have summarized the diverse pharmacological properties of some potent phytochemicals, which can be used as functional foods as well as nutraceuticals against sepsis-associated complications of SARS-CoV-2 infection. The phytochemicals explored in this article include quercetin, curcumin, luteolin, apigenin, resveratrol, and naringenin, which are the major phytoconstituents of our daily food intake. We have compiled the findings from various studies, including clinical trials in humans, to explore more into the therapeutic potential of each phytochemical against sepsis and COVID-19, which highlights their possible importance in sepsis-associated COVID-19 pathogenesis. We conclude that our review will open a new research avenue for exploring phytochemical-derived therapeutic agents for preventing or treating the life-threatening complications of sepsis associated with COVID-19.

Alamri ZZ. Apigenin attenuates indomethacin-induced gastric ulcer in rats: emphasis on antioxidant, anti-inflammatory, anti-apoptotic, and TGF-β1 enhancing activities. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024:10.1007/s00210-024-03200-w. [PMID: 38842560 DOI: 10.1007/s00210-024-03200-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 05/29/2024] [Indexed: 06/07/2024]
Abstract
Gastric ulcer disease is associated with significant morbidity and mortality rates. The most two common causes of the ulcer are Helicobacter pylori infection and non-steroidal anti-inflammatory drugs. In the past few decades, a significant decrease in the morbidity and mortality rate has been observed probably due to the discovery of proton pump inhibitors. However, the medications used to treat gastric ulcers impose several nauseous side effects. Therefore, recent studies focus on the use of natural products to treat gastric ulcers. In the current study, gastric ulcer was effectively induced using indomethacin, and the protective effect of apigenin, a potent antioxidant flavonoid, was assessed in comparison to omeprazole. The administration of a single oral indomethacin (50 mg/kg) induced gastric ulcer as manifested by hemorrhagic lesions in the gastric mucosa, increased ulcer index, and histopathological alterations. Indomethacin also increased lipid peroxidation, decreased the activities of the antioxidant enzymes superoxide dismutase (SOD) and catalase, increased the immunoreactivity of the inflammatory markers cyclo-oxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF-α), and nuclear factor-kappa B (NF-κB), increased the transcription of the apoptotic marker, Bax, and decreased that of the antiapoptotic Bcl-2. Indomethacin also decreased the immunoreactivity of transforming growth factor-beta 1 (TGF-β1). On the other hand, pretreatment with apigenin (10 and 20 mg/kg) resulted in a dose-dependent improvement in the macroscopic and microscopic features of the gastric mucosa in a manner comparable to that of omeprazole. The gastroprotective effects of apigenin may be attributed to its anti-inflammatory, anti-antioxidant, and anti-apoptotic activities as well as enhancing the expression of TGF-β1. Further experimental and clinical research is required to confirm activity of apigenin as anti-ulcer agent.

Abstract
BACKGROUND Natural components that can exert a wide range of anti-hair loss activity with fewer side effects are in high demand. The objective of this study was to investigate the anti-hair loss potential of Silybum marianum flower extract (SMFE) in vitro and in vivo. METHODS The effect of SMFE on dermal papilla cells was evaluated by measuring cell proliferation and VEGF production in hair follicle dermal papilla cells (HFDPCs). In addition, to confirm the effect of SMFE on dermal papilla senescence, SA-β-gal staining and senescence associated secretory phenotype (SASP) production such as IL-6 was observed in both replicative and hydrogen peroxide (H2 O2 )-induced senescence models. In a clinical study, hair growth was determined by reconstitution analysis after shaving the hair of the clinical subject's scalp and hair area. RESULTS SMFE increased the proliferation and VEGF production of HFDPCs. It also suppressed cellular senescence of HFDPCs and IL-6 production in replicative senescence and oxidative stress-induced senescence models. The hair density and total hair count at 16 and 24 weeks after using hair shampoo containing SMFE were significantly increased compared with those of the placebo group. CONCLUSION SMFE has the potential to be used as a natural ingredient for alleviating hair loss.

Abstract
Backgrounds In the present study, a cecal ligation and puncture (CLP)-induced experimental sepsis rat model was used to explore the effects of baicalein on inflammatory cytokine levels and oxidative stress as well as the possible regulatory role of nuclear factor-kappa B (NF-κB). Methods For that purpose, 42 Wistar albino rats were equally divided into control, sham, sepsis, B50 + S, B100 + S, S + B50, and S + B100 groups. The B50 + S and B100 + S groups received baicalein before the induction of sepsis, while the S + B50 and S + B100 groups received baicalein afterwards. Experimental sepsis in related groups is generated through ligation of cecum and a puncture in cecal wall. Serum samples were used for tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) analyses, and tissue Malondialdehyde (MDA), Superoxide dismutase (SOD), Glutathione (GSH), IL-6, and NF-κB levels were measured. Results Compared to the control group, there were significantly increases in the serum TNF-α, IL-6, tissue MDA, and NF-κB levels and decreases in the tissue SOD and GSH levels in the septic group (P < 0.05). Compared to the septic group, inflammation and oxidative stress were reduced in the baicalein-treated groups. Although all of the pre- and post-treatment protocols alleviated inflammation and oxidative stress to varying degrees, pre-treatment with 100 mg/kg was the most successful. Conclusions Findings of this study indicated that baicalein has the potential to reduce sepsis-related oxidative stress and inflammation in the lungs and that pathological outcomes could be regulated via NF-κB transcription factor activity.

Abstract
Three new compounds (1-2, 4) along with ten known ones (3, 5-13), were isolated from the whole plant of Erigeron breviscapus. Compounds 1 and 2, two novel C10 acetylenic acids and compound 4, a jasmone glucoside were elucidated by the detailed analysis of 1D and 2D NMR, HRESIMS spectra, and experimental and calculated electronic circular dichroism (ECD). Compounds 1-3 represent the first example of acetylenic acids incorporating C10 skeleton from E. breviscapus. In addition, the antioxidant effects of all compounds were evaluated by ferric reducing power, 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate acid) (ABTS) and 2.2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. Our results indicated the significant antioxidant activity of caffeoylquinic acids. Additionally, compounds 10-11 and 13 played protective role on alcoholic liver injury cells in a dose-dependent manner.

Abstract
Systemic inflammation includes a widespread immune response to a harmful stimulus that results in extensive systemic damage. One common example of systemic inflammation is sepsis, which is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Under the pro-inflammatory environment of sepsis, oxidative stress contributes to tissue damage due to dysfunctional microcirculation that progressively causes the failure of multiple organs that ultimately triggers death. To address the underlying inflammatory condition in critically ill patients, progress has been made to assess the beneficial effects of dietary supplements, which include polyphenols, amino acids, fatty acids, vitamins, and minerals that are recognized for their immuno-modulating, anticoagulating, and analgesic properties. Therefore, we aimed to review and discuss the contribution of food-derived supplementation in the regulation of inflammation from gene expression to physiological responses and summarize the precedented potential of current therapeutic approaches during systemic inflammation.

Abstract
In this study, the main hypothesis is that paeoniflorin may inhibit some cellular processes such as oxidative stress and inflammation. For this reason, we aimed to investigate the potential protective effects of a natural compound, paeoniflorin, on rat model of ovarian ischemia-reperfusion injury by detecting the oxidative stress parameters and inflammatory process parameters. 42 female Wistar-albino rats were divided into 6 random groups. The rats were subjected to 3-hour ischemia and 3-hour reperfusion process. Then, paeoniflorin at doses of 25, 50 and 100 mg/kg were applied 30 min before the reperfusion. The levels of pro-inflammatory (IL-1-β, IL-6, TNF-α) and anti-inflammatory (IL-10, TGF-β) cytokines were measured by ELISA. Similarly, IL-6, IL-10, TNF-α, NF-κB p65) positivity rates were detected by immunohistochemical staining. Additionally, oxidative stress parameters (MDA, GSH, SOD) were measured by tissue biochemistry. Ischemia-reperfusion injury caused significant increase in the levels of SOD, MDA, TNF-α, IL-1-β, IL-6 and NF-κB p65, while paeoniflorin treatments improved the related parameters in a dose-dependent manner. As a conclusion, our findings support the evidence that paeoniflorin has a potential protective effects on ovarian ischemia-reperfusion injury. Further detailed studies should be performed to shed light the molecular mechanism of these protective effects.

Abstract
Gossypol is a polyphenol from the cotton plant with anti-inflammatory and anti-oxidation activities and can also function as a histone deacetylase (HDAC) inhibitor. Sepsis is an inflammatory disease with high mortality. Inflammation, oxidative stress, and epigenetic factors are involved in sepsis and its complications. The biological activities of gossypol strongly suggest the potential effects of gossypol on sepsis. In the present study, the beneficial effects of gossypol on sepsis were evaluated. We established a cecal ligation and puncture (CLP) mouse model of sepsis and treated CLP mice with gossypol. The survival rate, serum level of myocardial injury markers, and myocardial level of oxidation markers were measured. We also administered gossypol to lipopolysaccharide (LPS)-treated primary cardiomyocytes. The production of pro-inflammatory cytokines, activation of protein kinase B (AKT) and IκB kinase (IKK), acetylation of histone, and expression of HDACs were measured. Gossypol prevented the death of CLP mice and ameliorated myocardial damage in CLP mice. Moreover, gossypol decreased oxidative factors, while promoting antioxidant production in CLP mice. Gossypol prevented LPS and cytosine-phosphate-guanosine-induced expression of pro-inflammatory cytokines, suppressed LPS-induced activation of AKT and IKK, inhibited histone acetylation, and decreased the expression of HDACs. In conclusion, gossypol ameliorates myocardial dysfunction in mice with sepsis.

Abstract
Sepsis is an abnormal immune response to infections and can trigger MODS. Despite the availability of advanced clinical techniques and monitoring methods, the mortality rate of the disease is still high, posing a heavy burden to patients and the whole society. Hence, the research on novel drugs and targets is particularly important. As a natural phyto-flavonoid, apigenin boasts anti-inflammatory, antioxidant, anti-cancer, anti-viral, and anti-bacterial effects. Besides, in-vitro experiments and animal models have also revealed the crucial role of apigenin in the treatment of infectious diseases and sepsis. In this context, this paper reviews the pharmacological activity and underlying mechanisms of action of apigenin in sepsis treatment and organ protection, as well as the potential apigenin-based therapeutic strategies against sepsis. Therefore, this review will shed new light on the scientific research and clinical treatment of sepsis.

Abstract
Artemisia anomala S. Moore exerts many pharmacological activities, including the removing of the blood stasis, relieving of the fever and analgesia, reducing the swelling and dampness. In this study, the extraction technology, chemical compositions and anti-inflammatory effect in vitro and mechanism of total flavonoids extract from Artemisia anomala S. Moore were studied. The optimal yield rate of total flavonoids extract was optimized by single factor experiments and response surface method, and the chemical constituents were analyzed by UPLC-QTOF-MS method; and the anti-inflammatory activity of the extract was evaluated with lipopolysaccharide induced RAW 264.7 cells. The highest extraction rate was 2.02% under these conditions of the concentration of ethanol 50%, the ultrasonic extraction time 30 min, and the ratio of solvent volume to material weight 20:1 (ml/g). In addition, the main components of total flavonoid extract were preliminarily identified and deduced based on mass spectrometry information and relevant literatures, and its stronger anti-inflammatory activity was demonstrated by reducing the phagocytosis, the content of nitric oxide and the level of related cytokines (tumor necrosis factor-α, interleukin-10, interleukin-6). Furthermore, it was further revealed that the anti-inflammatory effect of the extract was closely connected with the activation of TLR4-MyD88-NF-κB signalling pathway. This study indicated that the total flavonoids extract from Artemisia anomala S. Moore may be a better candidate anti-inflammatory natural medicine.

Two flavonoids, baicalein and naringin, are effective as anti-inflammatory and anti-oxidant agents in a rat model of polymicrobial sepsis. Immunopharmacol Immunotoxicol 2023; 45:597-606. [PMID: 36988563 DOI: 10.1080/08923973.2023.2197143] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 03/25/2023] [Indexed: 03/30/2023]
Abstract
INTRODUCTION In this study, our aim was to investigate the possible protective and therapeutic effects of these two flavonoids, baicalein, and naringin, in 50 and 100 mg/kg doses applied both before and after cecal ligation and puncture (CLP) procedures in a polymicrobial sepsis rat model, and evaluate the possible contribution of oxidative and inflammatory markers by immunological, biochemical, molecular, and histopathological methods. METHODS Sixty-six Wistar albino rats were divided into 11 groups. The pro-inflammatory (TNF-alpha, IL-1-beta, and IL-6) and anti-inflammatory (TGF-beta and IL-10) cytokine levels were measured by ELISA technique. CD3, CD68, and nuclear factor kappa B positivity rates were detected by immunohistochemical methods. Oxidative stress parameters (MDA, SOD, and GSH) were measured by tissue biochemistry. RESULTS Sepsis caused a significant increase in all pro-inflammatory cytokine levels and MDA activity. Also, it led to an increase in the positivities of CD3, CD68, and NF-κB markers. However, especially pre-CLP doses of baicalein and naringin inhibited the inflammation process by suppressing pro-inflammatory and increasing anti-inflammatory cytokine levels, as well as regulating the oxidative stress process by normalizing the oxidant/anti-oxidant enzyme levels. CONCLUSION Both pre- and post-application of baicalein and naringin are quite effective to prevent sepsis-caused cellular processes. This protective and therapeutic effects by baicalein and naringin in animals with sepsis seems to be originated from the high antioxidant capacity and inhibition of pro-inflammatory cytokine production. Thus, those natural agents may prove to be valuable protective agent against septic shock.

Abstract
In this study, our aim was to show both the single and combined effects of cisplatin and jaceosidin in SHSY-5Y neuroblastoma cells. For this purpose, we used MTT cellular viability assay, Enzyme-Linked Immunosorbent Assay (ELISA), Transmission Electron Microscopy (TEM), Immunofluorescence Staining Assay (IFA) and Western blotting (WB) assay. According to MTT findings, IC50 dose was detected as 50 µM cisplatin and 160 µM jaceosidin co-application. Therefore, experimental groups were finally selected as control, cisplatin, 160 µM jaceosidin and Cisplatin +160 µM jaceosidin. Cell viability was decreased in all groups, and the IFA findings confirmed the viability analysis. WB data indicated that matrix metalloproteinase 2 and 9 levels, as indicators of metastasis, decreased. While LPO and CAT levels increased in all treatment groups, it was observed that the activity of SOD decreased. When TEM micrographs were investigated, cellular damages were determined. In the light of these results, it can be said that cisplatin and jaceosidin have a potential to increase the effects of each other synergistically.

[PMID: 36721804 PMCID: PMC9871274 DOI: 10.34172/apb.2023.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 10/04/2021] [Accepted: 11/23/2021] [Indexed: 02/03/2023] Open
Abstract
Purpose: Colorectal cancer (CRC) is one of the most common and fatal malignancies in humans, still leading to serious morbidity and mortality. We here aimed to investigate the effects of flavonoid apigenin, which is considered to have anti-tumoral activity on CRC with high epidemiological prevalence, on cell proliferation and cell survivals, and the positive and negative dose-dependent effects of genetic or mutational alterations in SWH pathway components on HT29 CRC cell lines. Methods: Human colon cancer cell lines HT-29 were commercially available. In each flask, 5 groups were formed, each of which consists of 5,000 cells for different dose groups and the cells were plated. After a 24 and 48 h incubation period, cytotoxicity values were measured by MTT assay and gene expression was assessed by real-time polymerase chain reaction (PCR) analysis method. Results: Application of 12.5 and 25 nM of apigenin significantly increased cell death in HT29 cell lines. LATS1, STK3 and TP53 gene expression decreased in the same dose groups compared to control and other groups. Conclusion: It has been concluded that TP53 gene is strongly correlated with LATS1 and STK3 genes among the SWH pathway factors in the progression of CRC and could be used as an important marker for early detection of malignant transmission. In addition, it may be effective in CRC cases especially when 25 nM of apigenin applies for therapeutic purpose.

Alpha-Chymotrypsin Protects Against Acute Lung, Kidney, and Liver Injuries and Increases Survival in CLP-Induced Sepsis in Rats Through Inhibition of TLR4/NF-κB Pathway. Drug Des Devel Ther 2022; 16:3023-3039.

Abstract
Abstract Inflammation and oxidative stress play a major role in the development of sepsis and its associated complications, leading to multiple organ failure and death. The lungs, liver, and kidneys are among the early affected organs correlated with mortality in sepsis. Alpha-chymotrypsin (α-ch) is a serine protease that exerts anti-inflammatory, anti-edematous, and anti-oxidant properties. Purpose This study was undertaken to elucidate if the anti-inflammatory and anti-oxidant effects of α-ch observed in previous studies can alleviate lung, liver, and kidney injuries in a cecal ligation and puncture (CLP)-induced sepsis model, and thus decrease mortality. Materials and Methods Septic animals were given α-ch 2 h post CLP procedure. Sepsis outcomes were assessed in the lungs, liver, and kidneys. Separate animal groups were investigated for a survival study. Results CLP resulted in 0% survival, while α-chymotrypsin post-treatment led to 50% survival at the end of the study. Administration of α-chymotrypsin resulted in a significant attenuation of sepsis-induced elevated malonaldehyde (MDA) and total nitrite/nitrate (NOx) levels. In addition, there was a significant increase in reduced glutathione (GSH) content and superoxide dismutase (SOD) activity in the lungs, liver, and kidneys. Administration of α-ch reduced elevated tissue expression of toll-like receptor-4 (TLR4), nuclear factor kappa-B (NF-κB), myeloperoxidase (MPO), and inducible nitric oxide synthase (iNOS). Alpha-chymotrypsin resulted in a significant reduction in serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6). Alpha-chymotrypsin attenuated the rise in serum creatinine, cystatin C, blood urea nitrogen (BUN), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels that was observed in the septic group. In addition, α-ch significantly reduced the lung wet/dry weight ratio, total protein content, and leukocytic counts in bronchoalveolar lavage fluid (BALF). Histopathological examination of the lungs, liver, and kidneys confirmed the protective effects of α-ch on those organs. Conclusion α-ch has protective potential against sepsis through lowering tissue expression of TLR4, NF-κB, MPO, and iNOS leading to decreased oxidative stress and inflammatory signals induced by sepsis. This effect appeared to alleviate the damage to the lungs, liver, and kidneys and increase survival in rats subjected to sepsis.

Abstract
In cases of sepsis, the immune system responds with an uncontrolled release of proinflammatory cytokines and reactive oxygen species. The lungs, kidneys, and liver are among the early impacted organs during sepsis and are a direct cause of mortality. The aim of this study was to compare the effects of infliximab (IFX) and celecoxib (CLX) on septic rats that went through a cecal ligation and puncture (CLP) surgery to induce sepsis. This study included four groups: sham, CLP (untreated), and CLP-treated with CLX or IFX. The administration of “low dose” CLX or IFX was performed after 2 h following the induction of sepsis. Twenty-four hours following the induction of sepsis, the rats were sacrificed and blood samples were collected to evaluate kidney, liver, and lung injuries. MDA and NOx content, in addition to SOD activity and GSH levels, were evaluated in the tissue homogenates of each group. Tissue samples were also investigated histopathologically. In a separate experiment, the same groups were employed to evaluate the survival of septic rats in a 7-day observation period. The results of this study showed that treatment with either CLX or IFX ameliorated the three organs’ damage compared to septic-untreated rats, decreased oxidative stress, enhanced the antioxidant defense, and reduced serum cytokines. As a result, a higher survival rate resulted: 62.5% and 37.5% after the administration of CLX and IFX, respectively, compared to 0% in the CLP group after 7 days. No significant differences were observed between the two agents in all measured parameters. Histopathological examination confirmed the observed results. In conclusion, CLX and IFX ameliorated lung, kidney, and liver injuries associated with sepsis through anti-inflammatory and antioxidant actions, which correlated to the increase in survival observed with both of them.

Abstract
Radiation-induced intestinal injury (RIII) restricts the therapeutic efficacy of
radiotherapy in abdominal or pelvic malignancies. Also, intestinal injury is a major cause
of death following exposure to high doses of radiation in nuclear accidents. No safe and
effective prophylactics or therapeutics for RIII are currently available. Here, we
reported that the apigenin, a natural dietary flavone, prolonged the survival in c57 mice
after lethal irradiation. Apigenin pretreatment brought about accelerated restoration of
crypt-villus structure, including enhanced regenerated crypts, more differentiated
epithelium cells, and increased villus length. In addition, intestinal crypt cells in the
apigenin-treated group exhibited more proliferation and less apoptosis. Furthermore,
apigenin increased the expression of Nrf2 and its downstream target gene HO-1, and
decreased oxidative stress after irradiation. In conclusion, our findings demonstrate the
radioprotective efficacy of apigenin. Apigenin has the potential to be used as a
radioprotectant in cancer therapy and nuclear accidents.

Abstract
BACKGROUND Rehmannia Glutinosa Libosch. is applied for the treatment of renal and inflammatory-related diseases, and oleic acid (OA) is a compound isolated from Rehmannia Glutinosa Libosch.. Unfortunately, the pharmacological activity of OA on LPS treated acute kidney injury (AKI) has not been investigated. AIMS The research is aiming to probe the activities of OA on LPS-induced AKI. METHODS Information of OA effect on AKI were from network pharmacology. H&E staining, creatinine (CRE) and urea nitrogen (UN) were performed to evaluate the activities of OA on kidney function. Inflammatory factors in serum were measured by cytometric bead array. Increased ratio of reactive oxygen species (ROS) in kidney and immune cells in the peripheral blood were determined by flow cytometry (FCM). PPAR-γ, MAPK and apoptotic signaling pathways were measured by Western blot. Then, a metabolomics approach was utilized to investigate OA's response to AKI. The role of salirasib (FTS, Ras inhibitor) in OA acted on ROS, Ca2+, MMP and Ras signaling pathway in LPS treated NRK-52e cells were investigated by FCM and In-cell western. RESULTS It is proved that OA effetively ameliorated renal function, alleviated inflammatory response and oxidative stress, and transformed apoptotic, MAPK and PPAR-γ signaling pathways in mice with AKI, regulated phenylalanine metabolism, purine metabolism, sphingolipid metabolism, taurine and hypotaurine metabolism, moreover, the role of OA in injury of NRK-52e was blocked by FTS. CONCLUSION In a word, OA could alleviate AKI by restraining inflammation and oxidative stress via regulating the Ras/MAPKs/PPAR-γ signaling pathway, phenylalanine metabolism, purine metabolism, sphingolipid metabolism and taurine and hypotaurine metabolism, which might be a useful strategy for treating AKI.

Abstract
Diabetic foot infection caused by multidrug-resistant bacteria, is becoming serious problem. Moreover, polymicrobial biofilms contribute significantly to the persistent infections. In the present study, we investigated the effectiveness of novel toluidine blue conjugated chitosan coated gold-silver core-shell nanoparticles (TBO-chit-Au-AgNPs) mediated photodynamic therapy and demonstrate their use as a nontoxic antibacterial therapy to combat diabetic foot ulcer (DFU) caused by multi-drug resistant strains both in monomicrobial and polymicrobial state of infection. In vitro efficacy of TBO-chit-Au-AgNPs mediated photodynamic therapy (PDT) against polymicrobial biofilms was determined using standard plate count method and compared with that of monomicrobial biofilms of each species. Different anti-biofilm assays and microscopic studies were performed to check the efficacy of TBO-chit-Au-AgNPs mediated PDT, displayed significant decrease in the formation of biofilm. Finally, its therapeutic potential was validated in vivo type-2DFU. Cytokines level was found reduced, using nano-phototheranostic approach, indicating infection control. Expression profile of growth factors confirmed both the pathogenesis and healing of DFU. Hence, we conclude that TBO-chit-Au-AgNPs mediated PDT is a promising anti-bacterial therapeutic approach which leads to a synergistic healing of DFU caused by MDR bacterial strains.

Abstract
Apigenin, identified as 4', 5, 7-trihydroxyflavone, is a natural flavonoid compound that has many interesting pharmacological activities and nutraceutical potential including anti-inflammatory and antioxidant functions. Chronic, low-grade inflammation and oxidative stress are involved in both the initiation and progression of hypertension and hypertension-induced cardiac hypertrophy. However, whether or not apigenin improves hypertension and cardiac hypertrophy through modulating NADPH oxidase-dependent reactive oxygen species (ROS) generation and inflammation in hypothalamic paraventricular nucleus (PVN) has not been reported. This study aimed to investigate the effects of apigenin on hypertension in spontaneously hypertensive rats (SHRs) and its possible central mechanism of action. SHRs and Wistar-Kyoto (WKY) rats were randomly assigned and treated with bilateral PVN infusion of apigenin or vehicle (artificial cerebrospinal fluid) via osmotic minipumps (20 μg/h) for 4 weeks. The results showed that after PVN infusion of apigenin, the mean arterial pressure (MAP), heart rate, plasma norepinephrine (NE), Beta 1 receptor in kidneys, level of phosphorylation of PKA in the ventricular tissue and cardiac hypertrophy, perivascular fibrosis, heart level of oxidative stress, PVN levels of oxidative stress, interleukin 1β (IL-1β), interleukin 6 (IL-6), iNOS, monocyte chemotactic protein 1 (MCP-1), tyrosine hydroxylase (TH), NOX2 and NOX4 were attenuated and PVN levels of interleukin 10 (IL-10), superoxide dismutase 1 (Cu/Zn-SOD) and the 67-kDa isoform of glutamate decarboxylase (GAD67) were increased. These results revealed that apigenin improves hypertension and cardiac hypertrophy in SHRs which are associated with the down-regulation of NADPH oxidase-dependent ROS generation and inflammation in the PVN.

Abstract
We suppose that apigenin may inhibit the cellular process of sepsis-induced lung injury, which is considered to be a major cause of morbidity and mortality, and may improve inflammation and oxidative stress. The aim of this study was to investigate the potential protective effect of apigenin in a rat model of polymicrobial sepsis. Eight groups consisting of a total of 64 female Wistar albino rats were used for this study. Pro-inflammatory (TNF-α, IL-1-β, IL-6) and anti-inflammatory (TGF-β, IL-10) cytokine levels were measured with the enzyme-linked immunosorbent assay technique, oxidant/antioxidants parameters were measured using the spectrophotometric method and Bax and Caspase-3 immunohistochemical methods. TNF-α, TGF-β, IL-1β, and IL-6 levels significantly increased in the sepsis-induced group than in the control groups, while IL-10 levels decreased. Lipid peroxidase (LPO), an oxidative stress marker, increased, while the antioxidant defense parameters of superoxide dismutase (SOD), catalase (CAT) activities, glutathione (GSH) levels decreased. Although Bax and Caspase-3 immunoreactivity and H score levels significantly increased in the sepsis group, significant decreases were found in the groups treated with apigenin. In conclusion, we are of the opinion that apigenin treatment improves lung injury by inhibiting oxidative stress and inflammatory cell damage.

Abstract
The current was conducted to evaluate the ameliorating effect of Chlorella vulgaris (CV) extract against sodium nitrite-induced hepatotoxicity in rats. Forty-five rats were allocated randomly into 5 groups (n = 9). Group I (GI), control group: orally gavaged with normal saline daily. Group II (GII): orally gavaged with CV extract (70 mg/kg BW) for 3 months. Group III (GIII): orally gavaged with sodium nitrite (80 mg/kg BW) for 3 months. Group IV (GIV): received sodium nitrite as GIII and CV extract as GII simultaneously for 3 months. Group V (GV): received CV extract as GII and then, sodium nitrite as in GIII from the end of first month until the end of the experiment. Sodium nitrite significantly increased the activities of serum alanine aminotransferase, aspartate aminotransferase, and serum concentrations of tumor interleukin 1-β and necrosis factor α. In addition, it increased concentrations of malondialdehyde and nitric oxide and expression level of caspase-3 in the hepatic tissue. However, it decreased activities of hepatic glutathione peroxidase, catalase, and superoxide dismutase and induced degenerative and necrotic changes in hepatic tissues. In contrast, CV extract administration modulated sodium nitrite-induced inflammation, oxidative stress, and alteration in hepatic tissue function and architecture. This study indicated that CV extract modulated sodium nitrite-induced hepatic toxicity through decreasing oxidative stress and inflammation and enhancing antioxidant enzyme activities in hepatic tissue of rats.

Abstract
Biofilm mediated infection caused by multi-drug resistant bacteria are difficult to treat since it protects the microorganisms by host defense system, making them resistant to antibiotics and other antimicrobial agents. Combating such type of nosocomial infection, especially in immunocompromised patients, is an urgent need and foremost challenge faced by clinicians. Therefore, antimicrobial photodynamic therapy (aPDT) has been intensely pursued as an alternative therapy for bacterial infections. aPDT leads to the generation of reactive oxygen species (ROS) that destroy bacterial cells in the presence of a photosensitizer, visible light and oxygen. Here, we elucidated a possibility of its clinical application by reducing the treatment time and exposing curcumin to 20 J/cm2 of blue laser light, which corresponds to only 52 s to counteract vancomycin resistant Staphylococcus aureus (VRSA) both in vitro and in vivo. To understand the mechanism of action, the generation of total reactive oxygen species (ROS) was quantified by 2'-7'-dichlorofluorescein diacetate (DCFH-DA) and the type of phototoxicity was confirmed by fluorescence spectroscopic analysis. The data showed more production of singlet oxygen, indicating type-II phototoxicity. Different anti-biofilm assays (crystal violet and congo red assays) and microscopic studies were performed at sub-MIC concentration of curcumin followed by treatment with laser light against preformed biofilm of VRSA. The result showed significant reduction in the preformed biofilm formation. Finally, its therapeutic potential was validated in skin abrasion wistar rat model. The result showed significant inhibition of bacterial growth. Furthermore, immunomodulatory analysis with rat serum was performed. A significant reduction in expression of proinflammatory cytokines TNF-α and IL-6 were observed. Hence, we conclude that curcumin mediated aPDT with 20 J/cm2 of blue laser treatment (for 52 s) could be used against multi-drug resistant bacterial infections and preformed biofilm formation as a potential therapeutic approach.

Abstract
Human fetuses with trisomy 21 (T21) have atypical brain development that is apparent sonographically in the second trimester. We hypothesize that by analyzing and integrating dysregulated gene expression and pathways common to humans with Down syndrome (DS) and mouse models we can discover novel targets for prenatal therapy. Here, we tested the safety and efficacy of apigenin, identified with this approach, in both human amniocytes from fetuses with T21 and in the Ts1Cje mouse model. In vitro, T21 cells cultured with apigenin had significantly reduced oxidative stress and improved antioxidant defense response. In vivo, apigenin treatment mixed with chow was administered prenatally to the dams and fed to the pups over their lifetimes. There was no significant increase in birth defects or pup deaths resulting from prenatal apigenin treatment. Apigenin significantly improved several developmental milestones and spatial olfactory memory in Ts1Cje neonates. In addition, we noted sex-specific effects on exploratory behavior and long-term hippocampal memory in adult mice, and males showed significantly more improvement than females. We demonstrated that the therapeutic effects of apigenin are pleiotropic, resulting in decreased oxidative stress, activation of pro-proliferative and pro-neurogenic genes (KI67, Nestin, Sox2, and PAX6), reduction of the pro-inflammatory cytokines INFG, IL1A, and IL12P70 through the inhibition of NFκB signaling, increase of the anti-inflammatory cytokines IL10 and IL12P40, and increased expression of the angiogenic and neurotrophic factors VEGFA and IL7. These studies provide proof of principle that apigenin has multiple therapeutic targets in preclinical models of DS.

Abstract
Neuroinflammation leads to tissue injury causing many of the clinical symptoms of Multiple Sclerosis, an autoimmune disorder of the central nervous system (CNS). While T cells, specifically Th1 and Th17 cells, are the ultimate effectors of this disease, dendritic cells (DCs) mediate T cell polarization, activation, etc. In our previous study, Apigenin, a natural flavonoid, has been shown to reduce EAE disease severity through amelioration of demyelination in the CNS as well as the sequestering of DCs and other myeloid cells in the periphery. Here, we show that Apigenin exerts its effects possibly through shifting DC modulated T cell responses from Th1 and Th17 type towards Treg directed responses evident through the decrease in T-bet, IFN-γ (Th1), IL-17 (Th17) and increase in IL-10, TGF-β and FoxP3 (Treg) expression in cells from both normal human donors and EAE mice. RelB, an NF-κβ pathway protein is central to DC maturation, its antigen presentation capabilities and DC-mediated T cell activation. Apigenin reduced mRNA and protein levels of RelB and also reduced its nuclear translocation. Additionally, siRNA-mediated silencing of RelB further potentiated the RelB-mediated effects of Apigenin thus confirming its role in Apigenin directed regulation of DC biology. These results provide key information about the molecular events controlled by Apigenin in its regulation of DC activity marking its potential as a therapy for neuroinflammatory disease.

Abstract
Apigenin (API) is a natural flavonoid abundant in fruits and vegetables. The present study was undertaken to evaluate the effect of protein malnutrition (PMN) on acetaminophen (APAP)-induced hepatotoxicity, together with the protective effects of API, in male Wistar albino rats. In total, 64 male rats were divided into eight groups. Silymarin (SIL) (100 mg/kg, PO) as a reference standard and API (50 mg/kg, PO) were given to normal and APAP-induced hepatic injury in low protein-fed rats. The present results revealed that PMN significantly potentiated APAP-induced hepatotoxicity. Interestingly, the administration of SIL and API alleviated the induced damage, as revealed by reduced serum alanine aminotransferase and aspartate aminotransferase activities along with a significant improvement of the histopathological damage. API suppressed inflammatory response by reducing the interleukin-1β level and signal transducer and activator of transcription 3 expressions along with attenuating oxidative stress as shown by a significant reduction in liver contents of malondialdehyde and nitrite/nitrate as well as restoration of hepatic content of reduced glutathione and superoxide dismutase activity. API also counteracted apoptosis through downregulation of caspase-3 expression level. In conclusion, PMN greatly potentiated the hepatotoxic effects of APAP, and API produced a multimechanistic hepatoprotective activity that can be attributed to its antioxidant, anti-inflammatory, and antiapoptotic effects.

Abstract
Four new sesquiterpenes (1-2, 6-7), a new pyranone glycoside (10) along with six known compounds, were isolated from the whole plant of Erigeron breviscapus. Their planar structures were elucidated using extensive spectroscopic analyses. Brevisterpene A (1) and brevisterpene B (2) were proved to be a pair of diastereomer followed by mixtures resolution using chiral HPLC. Their absolute configurations were determined by ECD calculation. The relative configuration of brevisnoside B (7) was elucidated by a combined analysis of NOESY spectrum and computation of 13C NMR chemical shifts, and determination of the absolute configurations of 6 and 7 assisted by optical rotation calculations. Compounds 1 and 2 displayed moderate neuroprotective effects against H2O2-induced damage in SH-SY5Y cells.

Mercantepe T, Tümkaya L, Mercantepe F. Effects of Infliximab against Methotrexate Toxicity in Splenic Tissue via the Regulation of CD3, CD68, and C200R in Rats. Cells Tissues Organs 2019; 206:308-316. [DOI: 10.1159/000500905] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2018] [Accepted: 05/13/2019] [Indexed: 11/19/2022] Open
Abstract
Methotrexate (MTX), which has been used in clinical practice for approximately 70 years, is still widely employed in the treatment of rheumatoid arthritis (RA), psoriasis, and cancer. Although MTX toxicity causes nephrotoxicity, hepatotoxicity, bone marrow suppression, pulmonary fibrosis, and gastrointestinal damage, previous studies have not addressed splenic toxicity. This is the first study to examine the effectiveness of infliximab (INF) against MTX-induced toxicity in splenic tissues via the regulation of CD3, CD68, and C200R. We investigated the effects of MTX on macrophages and T lymphocytes in the spleen at the molecular level and examined the protective potential of the tumor necrosis factor (TNF)-α antagonist INF against MTX toxicity. Three groups of rats were set up. Group 1 received saline solution only, group 2 a single dose of MTX (20 mg/kg), and group 3 INF (7 mg/kg) before administration of a single dose of MTX (20 mg/kg). All injections were given intraperitoneally. Spleen tissues were removed 5 days after MTX administration and evaluated for CD3, CD68, and CD200R using immunohistochemical staining. Finally, the mean numerical density of CD3+, CD68+, and CD200R+ cells was estimated by a histopathologist using StereoInvestigator 8. MTX increased the numerical densities of CD3+, CD68+, and CD200R+ cells (p < 0.05). We also observed that INF reduced the numerical densities of these cells following MTX administration (p < 0.05). INF may, therefore, be a promising candidate for the prevention of the deleterious effects on spleen tissue of MTX, used in the treatment of RA and cancer.

[PMID: 30372841 DOI: 10.1016/j.biopha.2018.09.162] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2018] [Revised: 09/12/2018] [Accepted: 09/28/2018] [Indexed: 02/02/2023] Open
Abstract
BACKGROUNDS The aim of this study was to investigate the oxidative damage and inflammatory effects in the hippocampus and cerebellum in lipopolysaccharide (LPS)-induced sepsis model and possible ameliorating effects of pregabalin (PG). METHODS Twenty four female Wistar Albino rats (12 month old) were divided into 3 groups as follows: Group I (Control; 0.1 ml/gavage and i.p. saline, single dose), Group II (LPS; 5 mg/kg LPS, i.p, single dose), Group III (LPS + PG; 5 mg/kg LPS, i.p, single dose + 30 mg/kg, gavage, single dose). DNA damage, ischemia-modified albumin (IMA), total oxidant status (TOS), total antioxidant status (TAS) oxidative stress index (OSI), leukocyte (WBC), lymphocyte, neutrophil, hemoglobin (HGB), erythrocyte (RBC), and thrombocyte counts were measured in blood and brain tissues. Histopathological and immunohistochemical evaluation of Caspase- 3, G-CSF, IL-6, SAA, iNOS expressions were conducted using hippocampus and cerebellum tissues. RESULTS Comet analysis score, lymphocytes, neutrophils, WBC, IMA, TOS and OSI values were increased in Group II compared with to Group I (p < 0.05). IMA levels in blood, TOS and OSI levels in the brain were significantly decreased in Group III compared to Group II (p < 0.05). We observed increased hemorrhages, neutrophils, leukocytes infiltrations and neuron degeneration in Group II compared to Group I. Caspase 3, G-CSF, IL-6, SAA, iNOS expressions were increased in group II compared to Group I (p < 0.001). CONCLUSION Pregabalin partly ameliorated the damage caused by the exposure to LPS in hippocampus and cerebellum; however, further studies are needed to determine pregabalin's possible protective effects at different doses and with different techniques.

Abstract
Erigeron breviscapus, a traditional Chinese medicine, is clinically used for the treatment of occlusive cerebral vascular diseases. We developed a sensitive and reliable ultra-performance liquid chromatography-electrospray-tandem mass spectrometry (UPLC-ESI-MS/MS) method for simultaneous quantitation of chlorogenic acid, scutellarin, and scutellarein, the main active constituents in Erigeron breviscapus, and compared the pharmacokinetics of these active ingredients in sham-operated and middle cerebral artery occlusion (MCAO) rats orally administrated with Erigeron breviscapus extract. Plasma samples were collected at 15 time points after oral administration of the Erigeron breviscapus extract. The levels of chlorogenic acid, scutellarin, and scutellarein in rat plasma at various time points were determined by a UPLC-ESI-MS/MS method, and the drug concentration versus time plots were constructed to estimate pharmacokinetic parameters. The concentration of chlorogenic acid in the plasma reached the maximum plasma drug concentration in about 15 min and was below the limit of detection after 4 h. Scutellarin and scutellarein showed the phenomenon of multiple absorption peaks in sham-operated and MCAO rats, respectively. Compared with the sham-operated rats, the terminal elimination half-life of scutellarein in the MCAO rats was prolonged by more than two times and the area under the curve of each component in the MCAO rats was significantly increased. The results showed chlorogenic acid, scutellarin, and scutellarein in MCAO rats had higher drug exposure than that in sham-operated rats, which provided a reference for the development of innovative drugs, optimal dosing regimens, and clinical rational drug use.

Phytochemicals That Influence Gut Microbiota as Prophylactics and for the Treatment of Obesity and Inflammatory Diseases. Mediators Inflamm 2018; 2018:9734845. [PMID: 29785173 PMCID: PMC5896216 DOI: 10.1155/2018/9734845] [Citation(s) in RCA: 108] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2017] [Revised: 01/17/2018] [Accepted: 02/13/2018] [Indexed: 12/24/2022] Open
Abstract
Gut microbiota (GM) plays several crucial roles in host physiology and influences several relevant functions. In more than one respect, it can be said that you “feed your microbiota and are fed by it.” GM diversity is affected by diet and influences metabolic and immune functions of the host's physiology. Consequently, an imbalance of GM, or dysbiosis, may be the cause or at least may lead to the progression of various pathologies such as infectious diseases, gastrointestinal cancers, inflammatory bowel disease, and even obesity and diabetes. Therefore, GM is an appropriate target for nutritional interventions to improve health. For this reason, phytochemicals that can influence GM have recently been studied as adjuvants for the treatment of obesity and inflammatory diseases. Phytochemicals include prebiotics and probiotics, as well as several chemical compounds such as polyphenols and derivatives, carotenoids, and thiosulfates. The largest group of these comprises polyphenols, which can be subclassified into four main groups: flavonoids (including eight subgroups), phenolic acids (such as curcumin), stilbenoids (such as resveratrol), and lignans. Consequently, in this review, we will present, organize, and discuss the most recent evidence indicating a relationship between the effects of different phytochemicals on GM that affect obesity and/or inflammation, focusing on the effect of approximately 40 different phytochemical compounds that have been chemically identified and that constitute some natural reservoir, such as potential prophylactics, as candidates for the treatment of obesity and inflammatory diseases.

Abstract
PHARMACOLOGICAL RELEVANCE Artemisia argyi, a kind of ethnic drug, has a long-term use on gastric diseases and syndromes. AIM OF THE STUDY The aim of the study is to validate the traditional uses of A. argyi scientifically and to discover more efficient nature derived gastro-protective ethnomedicine and further elucidate the possible mechanisms. MATERIALS AND METHODS Sixty rats were randomly divided into control, model (ethanol-induced), reference (omeprazole-treated) and A. argyi extract (AT) (0.3, 0.1, 0.033g/mL) treated groups, respectively. The levels of biochemical indexes in tissues and serum and the activities of pepsin in gastric contents were measured after the sacrifice of rats. Moreover, the anti-inflammatory effects in LPS-induced RAW 264.7 cells of the isolated compounds were determined. RESULTS The studies indicated that A. argyi extract could exert strong protective effects on gastric mucosa in ethanol-induced rat model by regulating the levels of inflammatory factors, superoxide dismutase, and malonaldehyde, which were superior to those of positive control at 0.3g/mL. The isolated flavonoids could down-regulate the levels of pro-inflammatory cytokines on LPS-induced RAW 264.7 macrophage cells and eliminate free radicals in the anti-oxidative tests. The effects of eupatilin and jaceosidin, which were substituted by additional methoxy groups, were predominant, indicting the importance of methoxy to the activities. CONCLUSION The results confirmed that A. argyi can protect ethanol-induced rats from gastric mucosal injury through inhibiting inflammatory responses and ameliorating oxidative stress. A. argyi is suitable for people with gastric mucosal injuries or unhealthy dietary habits as a necessary dietary supplement, which will promote the planting and application of A. argyi in both agriculture and food industry.

Abstract
BACKGROUND/AIM The transcription factors Oct4 and Sox2 enhance the proliferation and pluripotency of human adipose tissue-derived mesenchymal stem cells (hAT-MSCs); however, the anti-inflammatory effects of Oct4- and Sox2-overexpressing hAT-MSCs (Oct4/Sox2-hAT-MSCs) are unclear. Here, we evaluated the anti-inflammatory effects of Oct4/Sox2-hAT-MSCs in vitro and in vivo. MATERIALS AND METHODS Supernatants from green-fluorescent protein (GFP)- and Oct4/Sox2-hAT-MSCs were used to treat lipopolysaccharide (LPS)-stimulated RAW264.7 cells and inflammatory cytokine expression was determined. In LPS-induced mice, GFP- and Oct4/Sox2-hAT-MSCs were injected intraperitoneally and survival rates, as well as sickness scores of mice, were monitored. RESULTS Decreased expression of pro-inflammatory cytokines was observed in Oct4/Sox2-hAT-MSC supernatant-exposed RAW264.7 cells compared to that in GFP-hAT-MSC supernatant-exposed RAW264.7 cells. The sickness score was reduced to 34.9% and the survival rate was increased by 11.1% in Oct4/Sox2-hAT-MSC-injected mice compared to that in GFP-hAT-MSC-injected mice. CONCLUSION Our findings provide important insights into the development of therapies utilizing Oct4/Sox2-hAT-MSCs in inflammatory diseases.

Abstract
The abuse of fructose in daily diet may cause cardiovascular diseases that seriously threaten human health, and both safe and efficient solutions need to be developed. We investigated whether apigenin can prevent the harmful impact of excessive fructose on cardiovascular events. Based on the reduction of percentage of body fat and systolic pressure as well as the improvements in insulin resistance, lipid metabolism, and pathological injury to the thoracic aorta, we suggested that high levels of fructose cause vascular injury and metabolic disorders, which can be improved to some extent by using apigenin. Fundamentally, apigenin down-regulates levels of phosphoinositide 3-kinase (PI3K), protein kinase B (AKT), and glucose transporter 1 (GLUT1), which increase with high concentrations of fructose. Moreover, the inflammation and asymmetric dimethylarginine (ADMA) levels increased in fructose group, but they decreased when the rats were fed with apigenin. The results suggest that PI3K/AKT/GLUT1 may have potential for alleviating cardiovascular injury, and apigenin can be an excellent candidate for supplements to ameliorate cardiovascular diseases related to high fructose consumption.

Abstract
Subcellular dysfunction and impaired metabolism derived from the complex interaction of cytokines and mediators with cellular involvement are on the basis of the cardiovascular response to sepsis. The lethal consequences of an infection are intimately related to its ability to spread to other organ sites and the immune system of the host. About one century ago, William Osler (1849-1919), a Canadian physician, remarkably defined the sequelae of the host response in sepsis: "except on few occasions, the patient appears to die from the body's response to infection rather than from it." Cardiac dysfunction has received considerable attention to explain the heart failure in patients progressing from infection to sepsis, but our understanding of the processes remains limited. In fact, most concepts are linked to a mechanical concept of the sarcomeric structure, and physiological data seems to be often disconnected. Cytokines, prostanoids, and nitric oxide release are high direct impact factors, but coronary circulation and cardiomyocyte physiology also play a prominent role in modulating the effects of monocyte adhesion and infiltration. Damage-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs) are involved in the host response. The identification of microRNAs, as well as the cyclic activation of the inflammatory cascade, has further added complexity to the scene. In this review, we delineate the current concepts of cellular dysfunction of the cardiomyocyte in the setting of sepsis and consider potential therapeutic strategies.

Apigenin Alleviates Endotoxin-Induced Myocardial Toxicity by Modulating Inflammation, Oxidative Stress, and Autophagy. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2017; 2017:2302896.

Abstract
Apigenin, a component in daily diets, demonstrates antioxidant and anti-inflammatory properties. Here, we intended to explore the mechanism of apigenin-mediated endotoxin-induced myocardial injury and its role in the interplay among inflammation, oxidative stress, and autophagy. In our lipopolysaccharide- (LPS-) induced myocardial injury model, apigenin ameliorated cardiac injury (lactate dehydrogenase (LDH) and creatine kinase (CK)), cell death (TUNEL staining, DNA fragmentation, and PARP activity), and tissue damage (cardiac troponin I (cTnI) and cardiac myosin light chain-1 (cMLC1)) and improved cardiac function (ejection fraction (EF) and end diastolic left ventricular inner dimension (LVID)). Apigenin also alleviated endotoxin-induced myocardial injury by modulating oxidative stress (nitrotyrosine and protein carbonyl) and inflammatory cytokines (TNF-α, IL-1β, MIP-1α, and MIP-2) along with their master regulator NFκB. Apigenin modulated redox homeostasis, and its anti-inflammatory role might be associated with its ability to control autophagy. Autophagy (determined by LAMP1, ATG5, and p62), its transcriptional regulator transcription factor EB (TFEB), and downstream target genes including vacuolar protein sorting-associated protein 11 (Vps11) and microtubule-associated proteins 1A/1B light chain 3B (Map1lc3) were modulated by apigenin. Thus, our study demonstrated that apigenin may lead to potential development of new target in sepsis treatment or other myocardial oxidative and/or inflammation-induced injuries.

Abstract
The aim of this study was to develop a novel mix micelles system composing of two biocompatible copolymers of Soluplus® and Pluronic F127 to improve the solubility, oral bioavailability of insoluble drug apigenin (AP) as model drug. The AP-loaded mixed micelles (AP-M) were prepared by ethanol thin-film hydration method. The formed optimal formulation of AP-M were provided with small size (178.5 nm) and spherical shape at ratio of 4:1 (Soluplus®:Pluronic F127), as well as increasing solubility of to 5.61 mg/mL in water which was about 3442-fold compared to that of free AP. The entrapment efficiency and drug loading of AP-M were 95.72 and 5.32%, respectively, and a sustained release of AP-M was obtained as in vitro release study indicated. Transcellular transport study showed that the cell uptake of AP was increased in Caco-2 cell transport models. The oral bioavailability of AP-M was 4.03-fold of free AP in SD rats, indicating the mixed micelles of Soluplus® and Pluronic F127 is an industrially feasible drug delivery system to promote insoluble drug oral absorption in the gastrointestinal tract.

Abstract
Objective To examine the potential relationship of EPCR polymorphisms and the risk of sepsis in a Chinese population. Methods Snapshot SNP genotyping assays and DNA sequencing methods were used to detect polymorphisms of the EPCR gene, rs2069948C/T (2532C/T) and rs867186A/G (6936A/G), in 64 patients with sepsis and in 113 controls. Soluble EPCR (sEPCR) was measured by ELISA. Results There were significant differences in the allele and genotype frequencies of EPCR gene rs2069948C/T and allele frequencies of rs867186A/G between male and female patients and controls. Females carrying rs2069948 C/T genotype or T allele and males carrying rs867186 A allele were associated with a significantly increased risk of sepsis. Plasma sEPCR levels of sepsis patients were higher than controls and showed no correlation with EPCR gene polymorphisms. Conclusions EPCR polymorphisms may be associated with increased risk of sepsis, but this has no effect on the release of sEPCR in patients with sepsis.

Abstract
Epigenetic modifications include DNA methylation, histone modification, and other patterns. These processes are associated with carcinogenesis and cancer progression. Thus, epigenetic modification-related enzymes, such as DNA methyltransferases (DNMTs), histone methyltransferases (HMTs), histone demethylases (HDMTs), histone acetyltransferases (HATs), and histone deacetylases (HDACs), as well as some related proteins, including methyl-CpG binding proteins (MBPs) and DNMT1-associated protein (DMAP 1), are considered as potential targets for cancer prevention and therapy. Numerous natural compounds, mainly derived from Chinese herbs and chemically ranging from polyphenols and flavonoids to mineral salts, inhibit the growth and development of various cancers by targeting multiple genetic and epigenetic alterations. This review summarizes the epigenetic mechanisms by which active compounds from Chinese herbs exert their anti-cancer effect. A subset of these compounds, such as curcumin and resveratrol, affect multiple epigenetic processes, including DNMT inhibition, HDAC inactivation, MBP suppression, HAT activation, and microRNA modulation. Other compounds also regulate epigenetic modification processes, but the underlying mechanisms and clear targets remain unknown. Accordingly, further studies are required.
