Abstract
BACKGROUND L-theanine is a unique non-protein amino acid in tea that is widely used as a safe food additive. We investigated the cardioprotective effects and mechanisms of L-theanine in myocardial ischemia-reperfusion injury (MIRI). METHODS The cardioprotective effects and mechanisms of L-theanine and the role of Janus Kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling were investigated in MIRI mice using measures of cardiac function, oxidative stress, and apoptosis. RESULTS Administration of L-theanine (10 mg/kg, once daily) suppressed the MIRI-induced increase in infarct size and serum creatine kinase and lactate dehydrogenase levels, as well as MIRI-induced cardiac apoptosis, as evidenced by an increase in Bcl-2 expression and a decrease in Bax/caspase-3 expression. Administration of L-theanine also decreased the levels of parameters reflecting oxidative stress, such as dihydroethidium, malondialdehyde, and nitric oxide, and increased the levels of parameters reflecting anti-oxidation, such as total antioxidant capacity (T-AOC), glutathione (GSH), and superoxide dismutase (SOD) in ischemic heart tissue. Further analysis showed that L-theanine administration suppressed the MIRI-induced decrease of phospho-JAK2 and phospho-STAT3 in ischemic heart tissue. Inhibition of JAK2 by AG490 (5 mg/kg, once daily) abolished the cardioprotective effect of L-theanine, suggesting that the JAK2/STAT3 signaling pathway may play an essential role in mediating the anti-I/R effect of L-theanine. CONCLUSIONS L-theanine administration suppresses cellular apoptosis and oxidative stress in part via the JAK2/STAT3 signaling pathway, thereby attenuating MIRI-induced cardiac injury. L-theanine could be developed as a potential drug to alleviate cardiac damage in MIRI.

Activation of AMPK/mTOR-Driven Autophagy and Suppression of the HMGB1/TLR4 Pathway with Pentoxifylline Attenuates Doxorubicin-Induced Hepatic Injury in Rats. Pharmaceuticals (Basel) 2024; 17:681. [PMID: 38931349 PMCID: PMC11206793 DOI: 10.3390/ph17060681] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 05/07/2024] [Accepted: 05/23/2024] [Indexed: 06/28/2024] Open
Abstract
Despite being an effective chemotherapeutic agent, the clinical use of doxorubicin (DOX) is limited by several organ toxicities including hepatic injury. Pentoxifylline (PTX) is a methylxanthine derivative with marked anti-inflammatory and anti-apoptotic features. It is unknown, however, whether PTX can mitigate DOX-evoked hepatotoxicity. This study aims to explore the potential hepatoprotective impact of PTX in DOX-induced hepatic injury and the underlying molecular mechanisms. Histopathology, immunohistochemistry, and ELISA were used to examine liver tissues. The current findings revealed that PTX administration to DOX-intoxicated rats mitigated the pathological manifestations of hepatic injury, reduced microscopical damage scores, and improved serum ALT and AST markers, revealing restored hepatic cellular integrity. These favorable effects were attributed to PTX's ability to mitigate inflammation by reducing hepatic IL-1β and TNF-α levels and suppressing the pro-inflammatory HMGB1/TLR4/NF-κB axis. Moreover, PTX curtailed the hepatic apoptotic abnormalities by suppressing caspase 3 activity and lowering the Bax/Bcl-2 ratio. In tandem, PTX improved the defective autophagy events by lowering hepatic SQSTM-1/p62 accumulation and enhancing the AMPK/mTOR pathway, favoring autophagy and hepatic cell preservation. Together, for the first time, our findings demonstrate the ameliorative effect of PTX against DOX-evoked hepatotoxicity by dampening the hepatic HMGB1/TLR4/NF-κB pro-inflammatory axis and augmenting hepatic AMPK/mTOR-driven autophagy. Thus, PTX could be utilized as an adjunct agent with DOX regimens to mitigate DOX-induced hepatic injury.

Abstract
Doxorubicin (DOX) is a widely used antitumor agent; however, its clinical application is limited by dose-related organ damage. Because organic cation/carnitine transporters (OCTN1 and OCTN2), which are critical for DOX uptake, are highly expressed in hepatocytes, we aimed to elucidate the role of these transporters in hepatic DOX uptake. The results indicated that inhibitors and RNA interference both significantly reduced DOX accumulation in HepG2 and HepaRG cells, suggesting that OCTN1/2 contribute substantially to DOX uptake by hepatocytes. To determine whether metformin (MET, an inhibitor of OCTN1 and OCTN2) ameliorates DOX-induced hepatotoxicity, we conducted in vitro and in vivo studies. MET (1-100 μM) inhibited DOX (500 nM) accumulation and cytotoxicity in vitro in a concentration-dependent manner. Furthermore, intravenous MET administration at 250 or 500 mg/kg or by gavage at 50, 100, or 200 mg/kg reduced DOX (8 mg/kg) accumulation in a dose-dependent manner in the mouse liver and attenuated the release of alanine aminotransferase, aspartate aminotransferase, and carboxylesterase 1. Additionally, MET reduced the distribution of DOX in the heart, liver, and kidney and enhanced the urinary elimination of DOX; however, it did not increase the nephric toxicity of DOX. In conclusion, our study demonstrated that MET alleviates DOX hepatotoxicity by inhibiting OCTN1- and OCTN2-mediated DOX uptake in vitro (mouse hepatocytes and HepaRG or HepG2 cells) and in mice.

Abstract
Background Doxorubicin, a commonly utilized anthracycline antibiotic and chemotherapeutic agent, has been associated with hepatotoxicity as an adverse effect. This study aimed to evaluate protective effects of zingerone, a bioactive compound derived from ginger renowned for its antioxidative attributes, on oxidative stress in doxorubicin-induced rat hepatotoxicity. Methods In this experimental study, a total of 48 male Wistar rats were allocated into six distinct groups. The first group received a control treatment of normal saline. The second group was administered an intraperitoneal dose of 20 mg/kg of doxorubicin on day 5. The third group received an oral dose of 40 mg/kg of zingerone for 8 days. The fourth, fifth, and sixth groups were administered zingerone at doses of 10, 20, and 40 mg/kg, respectively, for the same 8-day period. On day 5, all groups, except the control group, received an intraperitoneal injection of doxorubicin. Following a 72-hour interval, the animals were anesthetized, and blood samples were collected to assess serum factors. Moreover, portions of the liver tissue were subjected to histopathological analysis and assessment of oxidative stress parameters. Results The activity levels of serum enzymes, including aspartate transaminase (AST), alanine transaminase (ALT), and liver malondialdehyde (MDA), increased in the doxorubicin group. Conversely, the levels of other parameters such as glutathione peroxidase (GPX), superoxide dismutase (SOD), and glutathione (GSH) decreased. However, the co-administration of zingerone effectively reversed these levels, restoring them back to normal. Conclusions These findings suggest that zingerone, particularly at a high dose, exhibit a hepatoprotective effect in the doxorubicin-induced hepatotoxicity model.

Abstract
This study aimed to evaluate the hepatoprotective effect of combining bezafibrate with ginkgo biloba in doxorubicin-induced hepatotoxicity in rats. Thirty Wister albino rats were allocated into five groups: The negative control group, the positive control group, both received 1 ml of D.W, bezafibrate group received (100 mg/kg), ginkgo biloba group received (60 mg/kg) and the fifth group received bezafibrate + ginkgo biloba. All the treatments were for 14 days along with doxorubicin on days 11-14 except for the negative control. Blood samples were used for the measurement of ALT, AST, ALP, total protein, total bilirubin, albumin, globulin, GSH, catalase, and IL-6. Liver tissue was sent for histopathological examination. The combination of ginkgo biloba and bezafibrate significantly decreased AST, ALP, AST/ALT ratio, albumin/globulin ratio, and IL-6 with significant elevations of catalase, and GSH. The combination group produced more hepatoprotection. This could be attributed to the additive anti-inflammatory and antioxidant effects of the combination.

Abstract
Adriamycin (ADR) is an important chemotherapeutic drug, but it has serious side effects such as hepatotoxicity. This study aimed to evaluate whether N-acetylcysteine (NAC) has hepatoprotective effects against ADR-induced hepatotoxicity in rats. In addition, it was aimed to determine how Meteorin-Like (MtrnL), which has pleiotropic effects on immunology, inflammation, and metabolism, is affected by ADR and/or NAC applications in liver tissue. 28 rats were randomly assigned to one of four equal groups in the study: control (no treatment), NAC (150 mg/kg/day of NAC intraperitoneally (i.p), ADR (15 mg/kg only on the first day of the experiment), and ADR + NAC (ADR 15 mg/kg on the first day of the experiment + 150 mg/kg/day NAC i.p). After 15 days, liver enzyme levels in serum, oxidant/antioxidant parameters in liver tissue, histopathological changes, caspase 3 (Casp3) and heat shock protein 70 (HSP-70) immunoreactivities, and MtrnL levels were examined. Histopathological changes, liver enzyme levels, as well as HSP-70, and Casp3 immunoreactivities increased due to ADR application. Additionally, MtrnL levels in liver tissue were significantly increased as a result of ADR application. However, it was detected that the NAC application significantly regulated the ADR-induced changes. Furthermore, it was determined that NAC administration regulated the changes in ADR-induced oxidative stress parameters. We propose that NAC may exert a hepatoprotective effect by regulating ADR-induced altered oxidative stress parameters, MtrnL levels, Casp3, and HSP-70 immunoreactivities in the liver.

Abstract
Doxorubicin (DOX) is a widely used chemotherapeutic agent for various tumors treatment; apart from its chemotherapeutic activity, the traditional usage of DOX has been limited by its adverse effects on multiple organs, mainly hepatotoxicity. The molecular mechanisms underlying DOX hepatotoxicity are mainly due to the production of reactive oxygen species (ROS) inducing oxidative stress, diminishing antioxidant enzymes, apoptosis, inflammation, and mitochondrial dysfunction. Thus, there is an urgent need to develop a therapy that minimizes DOX hepatotoxicity and widens its use in various types of cancers without fear of its serious hepatotoxicity. Ginkgetin (GINK), a natural biflavonoid, exhibits diverse actions, including promising free radical scavenging, antioxidant, and anti-inflammatory activities. So, this study's objectives were to determine whether GINK could mitigate DOX's hepatotoxic effects and look into a putative hepatoprotective molecular pathway. Mice were divided into five groups: Normal control, control GINK 100, Untreated DOX group, and DOX groups treated with GINK (50 and 100 mg/kg) intraperitoneally daily for four days before DOX administration and an additional three days afterward. GINK 100 pretreatment showed marked protection from DOX hepatotoxicity and also attenuation of histopathological structural alterations. These outcomes were corroborated biochemically by a considerable decrease in alanine aminotransferases, aspartate aminotransferase, and alkaline phosphatase levels. GINK significantly augmented silent information regulator 1 and nuclear translocation of NF-E2-related factor 2 and repressed the expression and protein levels of forkhead box protein O1, inducible nitric oxide synthase, and P53 relative to DOX group. GINK alleviated oxidative stress and induced significant anti-inflammatory effects via suppression of interleukin-6, nuclear factor Kabba B, and iNOS respectively. This study is the first to investigate GINK's potentially beneficial effects in acute DOX hepatotoxicity, possibly exhibiting antioxidant, anti-inflammatory, and anti-apoptotic effects by modulation of Sirt1/FOXO-1/NF-κB Signal.

Abstract
Doxorubicin (DOX) is a highly effective chemotherapy agent prescribed for cancer treatment. However, the clinical use of DOX is limited due to off-target toxicity in healthy tissues. In this regard, hepatic and renal metabolic clearance results in DOX accumulation within these organ systems. Within the liver and kidneys, DOX causes inflammation and oxidative stress, which promotes cytotoxic cellular signaling. While there is currently no standard of care to treat DOX hepatic- and nephrotoxicity, endurance exercise preconditioning may be an effective intervention to prevent elevations in liver alanine transaminase (ALT) and aspartate aminotransferase (AST) and to improve kidney creatinine clearance. To determine whether exercise preconditioning is sufficient to reduce liver and kidney toxicity resulting from acute exposure to DOX chemotherapy treatment, male and female Sprague-Dawley rats remained sedentary or were exercise trained prior to saline or DOX exposure. Our findings demonstrate that DOX treatment elevated AST and AST/ALT in male rats, with no effects of exercise preconditioning to prevent these increases. We also showed increased plasma markers of renin-angiotensin-aldosterone system (RAAS) activation and urine markers of proteinuria and proximal tubule damage, with male rats revealing greater differences compared to females. Exercise preconditioning showed improved urine creatinine clearance and reduced cystatin c in males, while females had reduced plasma angiotensin II (AngII) levels. Our results demonstrate both tissue- and sex-specific responses related to the effects of exercise preconditioning and DOX treatment on markers of liver and kidney toxicity.

Abstract
Human colon microbiota produce a metabolite called urolithin A (URO A) from ellagic acid and linked compounds, and this metabolite has been demonstrated to have antioxidant, anti-inflammatory, and antiapoptotic activities. The current work examines the various mechanisms through which URO A protects against doxorubicin (DOX)-induced liver injury in Wistar rats. In this experiment, Wistar rats were administered DOX intraperitoneally (20 mg kg-1) on day 7 while given URO A intraperitoneally (2.5 or 5 mg kg-1 d-1) for 14 days. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma glutamyl transferase (GGT) were measured. Hematoxylin and eosin (HE) staining was used to evaluate histopathological characteristics, and then antioxidant and anti-inflammatory properties were evaluated in tissue and serum, respectively. We also looked at how active caspase 3 and cytochrome c oxidase were in the liver. The findings demonstrated that supplementary URO A therapy clearly mitigated DOX-induced liver damage. The antioxidant enzymes SOD and CAT were elevated in the liver, and the levels of inflammatory cytokines, such as TNF-α, NF-kB, and IL-6, in the tissue were significantly attenuated, all of which complemented the beneficial effects of URO A in DOX-induced liver injury. In addition, URO A was able to alter the expression of caspase 3 and cytochrome c oxidase in the livers of rats that were subjected to DOX stress. These results showed that URO A reduced DOX-induced liver injury by reducing oxidative stress, inflammation, and apoptosis.

The biosynthesis of EGCG, theanine and caffeine in response to temperature is mediated by hormone signal transduction factors in tea plant ( Camellia sinensis L.). FRONTIERS IN PLANT SCIENCE 2023; 14:1149182. [PMID: 37035086 PMCID: PMC10076774 DOI: 10.3389/fpls.2023.1149182] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Accepted: 03/06/2023] [Indexed: 06/19/2023]
Abstract
As the main flavor components of tea, the contents of epigallocatechin-3-gallate (EGCG), theanine and caffeine are regulated by ambient temperature. However, whether the biosynthesis of EGCG, theanine and caffeine in response to temperature is regulated by endogenous hormones and its mechanism is still unclear. In this study, tea cuttings cultivated in the phytotron which treated at different temperatures 15℃, 20℃, 25℃ and 30℃, respectively. The UPLC and ESI-HPLC-MS/MS were used to determine the contents of EGCG, theanine, caffeine and the contents of phytohormones in one leaf and a bud. The results showed that indoleacetic acid (IAA), gibberellin 1(GA1) and gibberellin 3 (GA3) were significantly correlated with the content of EGCG; Jasmonic acid (JA), jasmonate-isoleucine (JA-Ile) and methyl jasmonate (MeJA) were strongly correlated with theanine content; IAA, GA1 and gibberellin 4 (GA4) were significantly correlated with caffeine content at different temperatures. In order to explore the internal intricate relationships between the biosynthesis of these three main taste components, endogenous hormones, and structural genes in tea plants, we used multi-omics and multidimensional correlation analysis to speculate the regulatory mechanisms: IAA, GA1 and GA3 up-regulated the expressions of chalcone synthase (CsCHS) and trans-cinnamate 4-monooxygenase (CsC4H) mediated by the signal transduction factors auxin-responsive protein IAA (CsIAA) and DELLA protein (CsDELLA), respectively, which promoted the biosynthesis of EGCG; IAA, GA3 and GA1 up-regulated the expression of CsCHS and anthocyanidin synthase (CsANS) mediated by CsIAA and CsDELLA, respectively, via the transcription factor WRKY DNA-binding protein (CsWRKY), and promoted the biosynthesis of EGCG; JA, JA-Ile and MeJA jointly up-regulated the expression of carbonic anhydrase (CsCA) and down-regulated the expression of glutamate decarboxylase (CsgadB) mediated by the signal transduction factors jasmonate ZIM domain-containing protein (CsJAZ), and promoted the biosynthesis of theanine; JA, JA-Ile and MeJA also jointly inhibited the expression of CsgadB mediated by CsJAZ via the transcription factor CsWRKY and AP2 family protein (CsAP2), which promoted the biosynthesis of theanine; IAA inhibited the expression of adenylosuccinate synthase (CspurA) mediated by CsIAA via the transcription factor CsWRKY; GA1 and gibberellin 4 (GA4) inhibited the expression of CspurA mediated by CsDELLA through the transcription factor CsWRKY, which promoted the biosynthesis of caffeine. In conclusion, we revealed the underlying mechanism of the biosynthesis of the main taste components in tea plant in response to temperature was mediated by hormone signal transduction factors, which provided novel insights into improving the quality of tea.

Abstract
Doxorubicin is an effective chemotherapeutic agent applied in a wide variety of cancers. Despite its potent anticancer activity towards cancer cells, doxorubicin is also toxic to noncancerous cells. Therefore, doxorubicin can cause serious side effects in various organs, especially when dose escalation is required for patients with advanced disease. The liver is the major detoxification organ that metabolizes drugs, and hepatotoxicity is one of the most common adverse effects of doxorubicin administration. However, the exact mechanisms of doxorubicin-induced hepatotoxicity have not been clearly identified, and how doxorubicin treatment affects the biomolecular contents of normal human hepatocytes has rarely been studied. Synchrotron radiation-based Fourier transform infrared (SR-FTIR) microspectroscopy is a state-of-the-art analytical technique for characterizing the biomolecules present in cells. In this research, the biomolecular alterations of doxorubicin-treated normal human hepatocytes compared to untreated control cells were investigated at the single-cell level by combining SR-FTIR microspectroscopy with the Cell Counting Kit-8 (CCK-8) assay and flow cytometry. WRL68 human normal embryonic liver cells, which have been shown to be very promising for assessing the cytotoxicity of toxic compounds and investigating hepato-toxicology, were used in this research. Principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to further analyse the biomolecular contents of WRL68 cells. The order of lipid acyl chains and protein α-helix structures in doxorubicin-treated WRL68 cells was found to be distinctly changed, while the nucleic acids were altered relatively less. No alteration in the carbohydrate content was distinguishable after doxorubicin treatment. These results provide more comprehensive information about the biomolecular changes in hepatocytes induced by doxorubicin treatment and help to elucidate the mechanism of doxorubicin-induced hepatotoxicity. This research also proves that SR-FTIR microspectroscopy, combined with PCA and OPLS-DA, is a promising approach for investigating drug-cell interaction systems.

Metabolomic Signatures in Doxorubicin-Induced Metabolites Characterization, Metabolic Inhibition, and Signaling Pathway Mechanisms in Colon Cancer HCT116 Cells. Metabolites 2022; 12:metabo12111047.

Abstract
Doxorubicin (DOX) is a chemotherapeutic agent is used for various cancer cells. To characterize the chemical structural components and metabolic inhibition, we applied a DOX to HCT116 colon cancer cells using an independent metabolites profiling approach. Chemical metabolomics has been involved in the new drug delivery systems. Metabolomics profiling of DOX-applied HCT116 colon cancer cellular metabolisms is rare. We used 1H nuclear magnetic resonance (NMR) spectroscopy in this study to clarify how DOX exposure affected HCT116 colon cancer cells. Metabolomics profiling in HCT116 cells detects 50 metabolites. Tracking metabolites can reveal pathway activities. HCT116 colon cancer cells were evenly treated with different concentrations of DOX for 24 h. The endogenous metabolites were identified by comparison with healthy cells. We found that acetate, glucose, glutamate, glutamine, sn-glycero-3-phosphocholine, valine, methionine, and isoleucine were increased. Metabolic expression of alanine, choline, fumarate, taurine, o-phosphocholine, inosine, lysine, and phenylalanine was decreased in HCT116 cancer cells. The metabolic phenotypic expression is markedly altered during a high dose of DOX. It is the first time that there is a metabolite pool and phenotypic expression in colon cancer cells. Targeting the DOX-metabolite axis may be a novel strategy for improving the curative effect of DOX-based therapy for colon cancer cells. These methods facilitate the routine metabolomic analysis of cancer cells.

Co-Treatment With Resveratrol and FGF1 Protects Against Acute Liver Toxicity After Doxorubicin Treatment via the AMPK/NRF2 Pathway. Front Pharmacol 2022; 13:940406.

Abstract
Doxorubicin (DOX), an anthracycline type of chemotherapy, is an effective therapy for several types of cancer, but serious side effects, such as severe hepatotoxicity, limit its use currently. Accordingly, an effective therapeutic strategy to prevent DOX-related hepatotoxicity is urgently needed. Through the inhibition of oxidative stress, fibroblast growth factor 1 (FGF1) is an effect therapy for a variety of liver diseases, but its use is limited by an increased risk of tumorigenesis due to hyperproliferation. Resveratrol (RES), a natural product, inhibits the growth of many cancer cell lines, including liver, breast, and prostate cancer cells. Therefore, this study explored whether and how RES in combination with FGF1 can alleviate DOX-induced hepatotoxicity. The results showed that RES or FGF1 alone improved DOX-induced hepatic inflammation, apoptosis and oxidative stress, and these adverse effects were further attenuated after treatment with both RES and FGF1. Mechanistically, both in vivo and in vitro results showed that RES/FGF1 reduced oxidative stress and thereby alleviated liver injury by promoting nuclear translocation of nuclear factor erythroid 2-related factor 2 (NRF2) and subsequently upregulating expression of antioxidant proteins in an adenosine monophosphate-activated protein kinase (AMPK)-dependent manner. Together, our results not only demonstrate that co-treatment with RES and FGF1 significantly inhibited DOX-induced hepatic inflammation and apoptosis, but also that co-treatment with RES and FGF1 markedly suppressed DOX-induced hepatic oxidative stress, via targeting the AMPK/NRF2 pathway and subsequently ameliorating hepatic dysfunction. Thus, the combination of RES and FGF1 may provide a new therapeutic strategy for limiting DOX-induced hepatotoxicity.

Abstract
Doxorubicin (DOX), a common chemotherapeutic agent, suffers serious adverse effects including hepatotoxicity. Mokko lactone (ML) is a guainolide sesquiterpene with promising biological activities. The study aimed to evaluate the protection offered by ML against hepatotoxicity induced by DOX in rats. Our data indicated ML exhibited protective effects as evidenced by ameliorating the rise in serum activities of alanine transaminase, aspartate transaminase and alkaline phosphatase. This was confirmed histologically as ML prevented DOX-induced pathological alteration in liver architecture. Further, ML administration significantly prevented malondialdehyde accumulation, glutathione depletion and superoxide dismutase and catalase exhaustion. Antioxidant action of ML was associated with enhanced expression of the nuclear translocation of NF-E2-related factor 2 (Nrf2) and a lower expression of forkhead box protein O1 (FOXO1). Also, ML showed potent anti-inflammatory activities highlighted by decreased expression of interleukin 6, tumor necrosis factor α and nuclear factor κB (NF-κB). The anti-apoptotic effects of ML were associated with decreased Bax and enhanced Bcl-2 mRNA expression in liver tissues. ML caused a significant up-regulation in the expression of silent information regulator 1 (Sirt-1). Therefore, it can be concluded that ML prevents liver injury caused by DOX. This could partially be due to the ML regulatory activities on Sirt-1/FOXO1/NF-κB axis.

Abstract
Doxorubicin is an effective anti-neoplastic agent; the reported toxicities of DOX limit its use. Luteolin is a polyphenolic phytochemical that exhibits beneficial biological effects via several mechanisms. We investigate luteolin protective effects on hepatorenal toxicity associated with doxorubicin treatment in rats. For 2 weeks, randomly assigned rat cohorts were treated as follows: control, luteolin (100 mg/kg; per os), doxorubicin alone (2mg/kg; by intraperitoneal injection), co-treated cohorts received luteolin (50 and 100 mg/kg) in addition to doxorubicin. Treatment with doxorubicin alone significantly (p < 0.05) increased biomarkers of hepatorenal toxicities in the serum. Doxorubicin also reduced relative organ weights, antioxidant capacity, and anti-inflammatory cytokine interleukine-10. Doxorubicin also increased reactive oxygen and nitrogen species, lipid peroxidation, pro-inflammatory-interleukin-1β and tumour necrosis factor-α-cytokine, and apoptotic caspases-3 and -9). Morphological damage accompanied these biochemical alterations in the rat's liver and kidney treated with doxorubicin alone. Luteolin co-treatment dose-dependently abated doxorubicin-mediated toxic responses, improved antioxidant capacity and interleukine-10 level. Luteolin reduced (p < 0.05) lipid peroxidation, caspases-3 and -9 activities and marginally improved rats' survivability. Similarly, luteolin co-treated rats exhibited improvement in hepatorenal pathological lesions observed in rats treated with doxorubicin alone. In summary, luteolin co-treatment blocked doxorubicin-mediated hepatorenal injuries linked with pro-oxidative, inflammatory, and apoptotic mechanisms. Therefore, luteolin can act as a chemoprotective agent in abating toxicities associated with doxorubicin usage and improve its therapeutic efficacy.

Abstract
Doxorubicin (DOX) is a successful chemotherapeutic widely used for the treatment of a range of cancers. However, DOX can have serious side-effects, with cardiotoxicity and hepatotoxicity being the most common events. Oxidative stress and changes in metabolism and bioenergetics are thought to be at the core of these toxicities. We have previously shown in a clinically-relevant rat model that a low DOX dose of 2 mg kg-1 week-1 for 6 weeks does not lead to cardiac functional decline or changes in cardiac carbohydrate metabolism, assessed with hyperpolarized [1-13C]pyruvate magnetic resonance spectroscopy (MRS). We now set out to assess whether there are any signs of liver damage or altered liver metabolism using this subclinical model. We found no increase in plasma alanine aminotransferase (ALT) activity, a measure of liver damage, following DOX treatment in rats at any time point. We also saw no changes in liver carbohydrate metabolism, using hyperpolarized [1-13C]pyruvate MRS. However, using metabolomic analysis of liver metabolite extracts at the final time point, we found an increase in most acyl-carnitine species as well as increases in high energy phosphates, citrate and markers of oxidative stress. This may indicate early signs of steatohepatitis, with increased and decompensated fatty acid uptake and oxidation, leading to oxidative stress.

Abstract
The anti-neoplastic use of Doxorubicin (DOX) is hampered by several limitations, including reproductive toxicity. Luteolin (LUT)–a phytochemical-biological benefits include antioxidative and anti-inflammatory actions. Here we examined the protective effect of LUT against DOX-induced reproductive toxicity in an in vivo model—male albino Wistar rats—randomly assigned to five groups and treated as follows: Control (corn oil 2 mL/kg; per os), LUT (100 mg/kg; per os), DOX (2 mg/kg) by intraperitoneal injections, co-treated groups received LUT (50 and 100 mg/kg) with DOX. Treatment with DOX alone, significantly (p > 0.05), reduced biomarkers of testicular function, reproductive hormone levels, testicular and epididymal antioxidant, and anti-inflammatory cytokine. DOX increased (p > 0.05) sperm morphological abnormalities, as well as reactive oxygen and nitrogen species, lipid peroxidation, xanthine oxidase, a pro-inflammatory cytokine, and apoptotic biomarkers. Furthermore, testicular and epididymal histological lesion complemented the observed biochemical changes in treated rats. LUT co-treatment resulted in a dosage-dependent improvement in rats’ survivability, antioxidants capacity, reduction in biomarkers of oxidative stress, pro-inflammatory cytokines, and apoptosis in rat’s testis and epididymis. Also, LUT treatment resulted in improved histological features in the testis and epididymis, relative to DOX alone treated rats. LUT co-treatment abated DOX-mediated reproductive organ injuries associated with pro-oxidative, inflammatory, and apoptotic mechanisms. LUT supplementation may serve as a phyto-protective agent in alleviating male reproductive organ toxic injuries associated with Doxorubicin therapy.

Abstract
Doxorubicin (DOX) is a very effective broad-spectrum anticancer drug, yet its clinical application is badly restricted due to its serious side effects. Citronellal (CT), a specialized metabolite of plants found in Cymbopogon spp., is proved to exhibit many beneficial properties. In the current study, we intended to investigate the effect of CT on DOX-induced hepatotoxicity in rats. Rats were treated with CT (200 mg/kg b.w./day orally), and given DOX (2.5 mg/kg b.w./week, intraperitoneally) to induce hepatotoxicity for six consecutive weeks. The results showed that CT administration could attenuate the DOX-induced pathological changes of liver tissues and ameliorated the inappropriate alteration of liver function biomarkers (serum glutamic aspartate aminotransferase, glutamic pyruvic transaminase, and albumin) in serum and oxidative stress parameters (malondialdehyde, superoxide dismutase, and reduced glutathione) in the liver. Moreover, CT mitigated the Bax/Bcl-2 ratio and caspase-3 expression to inhibit cell apoptosis. Further study indicated that CT therapy could enhance the protein levels of p-PI3K, p-Akt, and CD31 in the liver. These results demonstrate that CT can ameliorate DOX-induced hepatotoxicity in rats mediated by antioxidative stress, antiapoptosis, and proangiogenesis.

Poult Sci 2020; 99:5625-5636. [PMID: 33142480 PMCID: PMC7647716 DOI: 10.1016/j.psj.2020.07.016] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Revised: 07/14/2020] [Accepted: 07/25/2020] [Indexed: 01/30/2023] Open
Abstract
L-theanine (γ-Glutamylethylamide) is a nonprotein water soluble amino acid (AA) mostly found in leaves of Camellia sinensis (green tea). This is a key component of green tea and is considered as the most abundant form of total AAs in green tea (i.e., about 50%). L-theanine is an exclusive taste ingredient of tea producing an attractive flavor and aroma in tea. It has biological effects such as antioxidant, growth promoter, immune booster, anti-stresser, hepatoprotective, antitumor, antiaging, antimicrobial, anti-inflammatory, and antianxiety activities that are worth noticing. It could reduce the oxidative impairment by reducing the synthesis of reactive oxygen species, oxidative parameters, and lipid damage as well as increasing the activity of antioxidant enzymes. The oral ingestion of L-theanine enhanced γδ T-cell proliferation. Therefore, it is being considered an essential compound of green tea that has the ability to improve immune function. The L-theanine can be used as a potential treatment for hepatic injury and immune-related liver diseases via the downregulation of the inflammatory response through the initiation of nitric oxide synthesis and glutathione production which are likely to be critical for the control of hepatic diseases as well as for the improvement of immune function. In addition, it could be used as a best natural feed additive with a potent antistressor by decreasing the levels of corticosterone, dopamine, and noradrenaline. After systematically reviewing the literature, it is noticed that most studies were carried out on mice, pig, human, and butterfly; while dietary supplementation studies of L-theanine in animal and poultry especially among broilers are very limited because of less awareness of this AA. So, the aim of this review is to encourage the veterinarian and poultry researchers to conduct more research at the molecular level about this AA to expose its more beneficial effects and its mechanism of absorption for potential use of this unique green tea AA in poultry nutrition.

Abstract
Thiophanate-methyl (TM) is widely used all over the world and is a typical example of pesticide residues, which can be detected in the soil, and even in vegetables and fruits. However, the molecular mechanisms underlying the hepatotoxicity of TM are not well understood. In this study, we utilized zebrafish to comprehensively evaluate the hepatotoxicity of TM and explore how the molecular mechanisms of hepatotoxicity are induced. The zebrafish larvae were exposed in 6.25, 12.5 and 25 mg/L TM from 72 to 144 hpf, while the adults were exposed in 2, 4 and 6 mg/L TM for 28 days. Here, we found that 12.5 and 25 mg/L TM induces specifically serious hepatotoxicity but not the toxicity of other organs in zebrafish larvae and adults. Moreover, it might triggered hepatotoxicity by activating the caspase-3 through apoptotic pathways and oxidative stress in zebrafish. Subsequently, this resulted in a metabolic imbalance in the zebrafish's liver. In conclusion, our results disclosed the fact that TM may induce severe hepatotoxicity by mediating activation of caspase-3 and oxidative stress in zebrafish.

Abstract
Chemotherapeutic antibiotic doxorubicin belongs to the anthracycline class, slaughters not only the cancer cells but also non-cancerous cells even in the non-targeted organs thereby resulting in the toxicity. The liver is primarily involved in the process of detoxification and this mini-review we focused mainly to investigate the molecular mechanisms heading hepatotoxicity caused due to doxorubicin administration. The alterations in the doxorubicin treated liver tissue include vacuolation of hepatocytes, degeneration of hepatocyte cords, bile duct hyperplasia and focal necrosis. About the literature conducted, hepatotoxicity caused by doxorubicin has been explained by estimating the levels of liver serum biomarkers, ROS production, antioxidant enzymes, lipid peroxidation, and mitochondrial dysfunction. The liver serum biomarkers such as ALT and AST, elated levels of free radicals inducing oxidative stress characterized by a surge in Nrf-2, FOXO-1 and HO-1 genes and diminution of anti-oxidant activity characterized by a decline in SOD, GPx, and CAT genes. The augmented levels of SGOT, SGPT, LDH, creatine kinase, direct and total bilirubin levels also reveal the toxicity in the hepatic tissue due to doxorubicin treatment. The molecular insight of hepatotoxicity is mainly due to the production of ROS, ameliorated oxidative stress and inflammation, deteriorated mitochondrial production and functioning, and enhanced apoptosis. Certain substances such as extracts from medicinal plants, natural products, and chemical substances have been shown to produce an alleviating effect against the doxorubicin-induced hepatotoxicity are also discussed.

Abstract
AIMS Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response against infection that triggers systemic inflammatory response syndrome. l-theanine (LT), a glutamate derivative, is a non-protein amino acid derived from tea (Camellia sinensis), and a valuable nutraceutical product used as an additive in the food industry. This study we aimed to investigate whether LT would exert any therapeutic effect on liver and kidney tissues in Sprague Dawley rats with sepsis induced with cecal ligation and puncture (CLP). MAIN METHODS Rats were divided into four groups; sham, CLP, CLP+LT1 (2x250 mg/kg) and CLP+LT2 (2 × 750 mg/kg). Liver and kidney tissues were subjected to histopathological examination. Apoptotic index percentages (AI%) were examined using the TUNEL method. The oxidized glutathione to total glutathione (GSSG/TGSH) ratio (as a marker of oxidative stress, levels of caspase-3 (a marker of apoptosis), glutathione peroxidase (GPx) and glutathione S-transferase (GST) (as antioxidant enzymes), inducible nitric oxide synthase (iNOS) and the tumor necrosis factor-α to Interleukin-10 ratio (TNF-α/IL-10) (as markers of inflammation) were investigated using commercial kits. Levels of malondialdehyde (MDA) (a marker of oxidative stress) were determined spectrophotometrically. KEY FINDINGS A high dose of LT exhibited more significant effects in reducing oxidative stress, inflammation and apoptosis than a low dose of LT in liver and kidney tissues with CLP-induced sepsis (p < 0.05). SIGNIFICANCE Our results indicated that LT significantly and dose-dependently inhibited sepsis induced liver and kidney injury. This effect may be attributed to the antioxidant, anti-inflammatory, and anti-apoptotic activities of LT.

Abstract
The therapeutic efficacy of anti-cancer nanomedicines is generally constrained due to limited accumulation in the solid tumors. In this study, we developed a biomimetic nano-carrier to enhance the chemo-therapeutic efficacy of doxorubicin and icotinib in a chemo-resistant non-small cell lung cancer (NSCLC) cell line harboring a mutation in the epidermal growth factor receptor (EGFR). The unique nanomedicine was prepared by coating with targeting cancer cell membrane proteins as highly specific ligands. The resulting biomimetic nanoparticles were highly stable and exhibited superior homologous targeting ability in vitro compared with control groups. In a mouse EGFR-mutated NSCLC xenograft model, intravenous injection of the biomimetic nanomedicine led to a high tumour inhibition rate (87.56%). Histopathological analysis demonstrated that the biomimetic nanomedicine had minimal side effects. Taken together, a cancer cell membrane-based biomimetic drug carrier can significantly enhance drug accumulation and improve therapeutic efficacy in cancers.

Acute and Subchronic Oral Toxicity of Fermented Green Tea with Aquilariae Lignum in Rodents. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:8721858.

Abstract
Green tea is generally considered safe, but there have been concerns regarding side effects relating to the main component, catechins, especially hepatotoxicities. We have previously shown beneficial effects of fermented green tea with Aquilariae Lignum (fGT) via an oral route in diabetic and obese models. Thus, the toxicological safety of fGT was assessed at limited oral doses for a rodent. Mice or rats of both genders were orally administered distilled water as a control and fGT at 2.0, 1.0, and 0.5 g/kg. There were no mortalities or gross abnormalities in the fGT groups for 2 weeks following the single oral dose in mice. No fGT-relevant abnormalities were found in postmortem and histopathological examinations, suggesting LD50 of fGT at more than 2.0 g/kg with no specific target organs. There were also no fGT-relevant mortalities or abnormal signs in the repeated oral dose for 13 weeks in rats. In the fGT groups, no body weight changes or daily metabolic changes were found, and hematological and serum biochemical ranges were normal. The postmortem and histopathological examinations revealed few fGT-related abnormalities in most of the organs including the liver, although slight lymphoid cell hyperplasia in the lymph node was observed in a few rats with fGT at 2.0 g/kg. This may be secondary to increased immune response to the highest dose because there were no histopathological lesions or organ weight changes. It suggests nontoxic safety of fGT at up to 2.0 g/kg, which provides useful information for clinical use.

Abstract
Chemotherapy is the most common and powerful cancer treatment. Although the nasty side effects seriously influence the clinical practice, no better ways can displace it. Therefore, searching for safe and effective strategies designed to ameliorate chemotherapy-induced toxicity has become an urgent issue in cancer research area. In clinical, a medicinal and edible formula YH0618 showed the effects of reducing the DOX-induced toxicity, especially improving alopecia, nail discoloration, skin hyperpigmentation and fatigue. This study was to investigate the role and mechanism of YH0618 in ameliorating DOX-induced toxicity by in vitro and in vivo experiments. YH0618 selectively attenuated DOX-induced growth inhibition and apoptosis in human normal liver L02 cells and kidney HEK-293 cells, and simultaneously potentiated the anti-cancer effect of DOX in breast cancer MCF-7 and MDA-MB-231 cells by apoptosis pathways. Western blotting results revealed that YH0618 attenuated DOX-induced apoptosis in normal liver and kidney cells through FOXO4-mediated mitochondria-dependent mechanism. Animal experiments demonstrated that, YH0618 did not interfere in DOX-induced reduction in tumor volume and significantly improved DOX-induced hair loss and the increase of alanine aminotransferase (ALT). Histological characteristics showed that YH0618 attenuated DOX-induced heart, liver and kidney damage. The study may shed light on the potential application of YH0618 as a novel medicinal food against chemotherapy-induced toxicity.

Abstract
Background Menthol is widely used as a constituent of functional foods and chemical drugs. In the present study, we investigated changes in the expression of cytochrome P450 isoform CYP3A4mRNA after treating human hepatocellular carcinoma HepG2 cells with menthol. We also examined the effects of pretreatment with menthol on the cytotoxic activity of paclitaxel (PAC) and vincristine (VIN), which are substrates of CYP3A4, in the cells. Methods HepG2 cells were maintained in Dulbecco's Modified Eagle's Medium. Expression of CYP3A4 was examined by the real-time polymerase chain reaction. Survival rate of HepG2 cells was evaluated by the MTT assay. Results The gene expression level of CYP3A4 in HepG2 cells was significantly reduced by treatment with menthol for 1 day. The viability of HepG2 cells was not affected by treatment with menthol alone once a day for two consecutive days. The degree of reduction in cell viability by PAC or VIN in HepG2 cells was significantly increased by menthol treatment for 24 h prior to exposure to these anti-cancer drugs. Conclusions These results demonstrate that menthol enhanced the anti-tumor effects of PAC and VIN through the downregulation of CYP3A4 in HepG2 cells without exerting cytotoxic activity.

Abstract
Theanine, a unique bioactive constituent from tea ( Camellia sinensis) leaves, is widely used as a functional ingredient and dietary supplement. To evaluate the anti-inflammatory and hepatoprotective effects of theanine and its molecular mechanism, the lipopolysaccharide (LPS)-induced inflammation mouse model was employed in this study. The survival rate of mice in the theanine-treated group increased significantly compared with that of LPS-only group mice. Furthermore, ICR male mice were randomly divided into three or four groups: control, LPS (LPS treatment only), LPS + theanine (20 mg/kg/day), and theanine (theanine treatment only). The results showed that compared with the LPS group, the liver damage and oxidative stress of the theanine-treated group decreased significantly, based on plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) concentrations, hepatic total superoxide dismutase (T-SOD), and malondialdehyde (MDA) levels, and histological scores and apoptosis [terminal deoxynucleotide transferase-mediated deoxyuridine triphosphate nick end-labeling (TUNEL) staining and caspase-3 activity] in the liver tissues. Furthermore, compared with no treatment, pretreatment with theanine significantly decreased the release of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, inhibited the expression of several inflammatory factors (including IL-1β, TNF-α, and IL-6), and increased the IL-10/interferon (IFN)-γ ratio in the hepatic tissues. In the LPS-induced inflammation model, theanine inhibited the expression of proinflammatory mediators involved in the nuclear factor-kappa B (NF-κB) pathway, such as inducible nitric oxide synthase (iNOS) and matrix metalloproteinase-3 (MMP-3), and attenuated the phosphorylation of NF-κB in the hepatic tissues. Moreover, theanine suppressed the acute-phase response (elevated nitric oxide and C-reactive protein levels). Furthermore, theanine suppressed the LPS-induced inflammatory state by normalizing hypothalamic-pituitary-adrenal (HPA) axis hyperactivity. Taken together, the results suggest that theanine potentially ameliorates LPS-induced inflammation and acute liver injury; molecular mechanism of action may involve normalization of HPA axis hyperactivity and inactivation of the NF-κB signaling pathway.

Abstract
Doxorubicin (DOX) is a highly potent anti-neoplastic agent widely used in clinical practice, but its dosage and duration of administration are strictly limited due to dose-related organ damage. In the present study, we examined whether theanine, an amino acid derivative found in green tea leaves, can protect against DOX-induced acute nephrotoxicity in rats. Decreases in the creatinine clearance by DOX administration were attenuated by concurrent treatment with theanine, which was consistent with the change in histological renal images assessed by microscopic examination. Theanine had no effect on the distribution of DOX to the kidney. The production of lipid peroxide in the kidney after DOX administration was suppressed by concurrent treatment with theanine. Reduced glutathione content, but not superoxide dismutase activity, was decreased following DOX administration, whereas this change was suppressed when theanine was given in combination with DOX. These results suggest that theanine prevents DOX-induced acute nephrotoxicity through its antioxidant properties.

Abstract
The present study investigated the effects and potential mechanisms of action of magnesium isoglycyrrhizinate (MgIG) in doxorubicin (DOX)-treated mice. Histopathological analysis and western blot analysis were conducted in the liver and heart tissues and biochemical analysis of the serum was performed. The results revealed that MgIG (10, 20 and 40 mg/kg/day) could protect the structure and functions of the liver and heart by inhibiting the activities of the myocardial enzymes creatine kinase (CK), CK-MB and lactate dehydrogenase and the hepatic-specific enzymes aspirate aminotransferase and alanine aminotransferase, increasing the activities of the antioxidants superoxide dismutase and glutathione peroxidase, and inhibiting cellular apoptosis induced by DOX (30 mg/kg). These results demonstrate that inhibiting lipid peroxidation and reducing myocardial and hepatocyte apoptosis may be one of the mechanisms by which MgIG exhibits hepatoprotective and cardioprotective effects in DOX-treated mice.

Abstract
Ipomoea aquatica Forssk. (Convolvulaceae) is an aquatic vegetable traditionally employed against toxic effects of xenobiotics. The present study has been designed to investigate the molecular mechanism underlying the beneficial role of the edible (aqueous) leaf extract of I. aquatica (AEIA) against doxorubicin (Dox)-induced liver injury. AEIA exhibited a dose-dependent (∼400 μg/ml) increase in cell viability against Dox (1 μM) in isolated rodent hepatocytes. AEIA (400 μg/ml) prevented the Dox-induced increase in ROS, redox imbalance, and activation of mitogen activated protein kinases (MAPK) and intrinsic pathway of apoptosis in hepatocytes. In the in vivo assay, administration of AEIA (100 mg/kg, p.o.) against Dox (3 mg/kg, i.p.) also reduced the oxidative impairment, DNA fragmentation, ATP formation, and up-regulated the mitochondrial co-enzymes Qs in the liver tissues of Wistar rats. Histological assessments were in agreement with the biochemical findings. Substantial quantities of phyto-antioxidants in AEIA may mediate its beneficial function against Dox-induced liver injury.

Abstract
Doxorubicin (DOX), a kind of wide-spectrum chemotherapeutic drug, can cause severe side effects in clinical use. To enhance its antitumor efficacy while reducing the side effects, two kinds of nanoparticles with desirable compositions and properties were assembled using optimally synthesized hydroxyethyl starch-grafted-polylactide (HES-g-PLA) copolymers and utilized as partner nanocarriers. The large empty HES-g-PLA nanoparticles (mean size, ca. 700 nm), at an optimized dose of 400 mg/kg, were used to block up the reticuloendothelial system in tumor-bearing mice 1.5 h in advance, and the small DOX-loaded HES-g-PLA nanoparticles (mean size, ca. 130 nm) were subsequently applied to the mice. When these partner nanocarriers were administered in this sequential mode, the released DOX had a significantly prolonged plasma half-life time and much slower clearance rate as well as a largely enhanced intratumoral accumulation as compared to free DOX. In vivo antitumor studies demonstrated that the DOX-loaded HES-g-PLA nanoparticles working together with their partner exhibited remarkably enhanced antitumor efficacy in comparison to free DOX. In addition, these HES-g-PLA partner nanocarriers showed negligible damage to the normal organs of the treated mice. Considering safe and efficient antitumor performance of DOX-loaded HES-g-PLA nanoparticles, the newly developed partner nanocarriers in combination with their administration mode have promising potential in clinical cancer chemotherapy.

Abstract
Cardiotoxicity is a limiting factor of doxorubicin (DOX)-based anticancer therapy. Due to its beneficial effects, we investigated whether standardized extract of Melissa officinalis (MO) can attenuate doxorubicin-induced cardiotoxicity and can potentiate the efficacy of DOX against human breast cancer cells. MO was administered orally to male albino rats once daily for 10 consecutive days at doses of 250, 500 and 750 mg/kg b.wt. DOX (15 mg/kg b.wt. i.p.) was administered on the 8th day. MO protected against DOX-induced leakage of cardiac enzymes and histopathological changes. MO ameliorated DOX-induced oxidative stress as evidenced by decreasing lipid peroxidation, protein oxidation and total oxidant capacity depletion and by increasing antioxidant capacity. Additionally, MO pretreatment inhibited inflammatory responses to DOX by decreasing the expressions of nuclear factor kappa-B, tumor necrosis factor-alpha and cyclooxygenase-2 and the activity of myeloperoxidase. MO ameliorated DOX-induced apoptotic tissue damage in heart of rats. In vitro study showed that MO augmented the anticancer efficacy of DOX in human breast cancer cells (MCF-7) and potentiated oxidative damage and apoptosis. Thus, combination of DOX and MO may prove future cancer treatment protocols safer and more efficient.

Safety and anti-hyperglycemic efficacy of various tea types in mice. Sci Rep 2016; 6:31703. [PMID: 27531374 PMCID: PMC4987693 DOI: 10.1038/srep31703] [Citation(s) in RCA: 46] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2016] [Accepted: 07/25/2016] [Indexed: 12/04/2022] Open
Abstract
Tea, a beverage consumed worldwide, has proven anti-hyperglycemic effects in animal models. Better efficacies of tea beverages are frequently associated with high-dose levels, whose safety attracts considerable attention. Based on the inherent nature of tea catechin oxidation, fresh tea leaves are manufactured into diverse tea types by modulating the oxidation degree of catechins. The present study aimed to assess various tea types for their safety properties and anti-hyperglycemic effects. Mice were allowed free access to tea infusion (1:30, w/v) for one week, and the rare smoked tea caused salient adverse reactions, including hepatic and gastrointestinal toxicities; meanwhile, the widely-consumed green and black teas, unlike the rare yellow tea, suppressed growth in fast-growing healthy mice. When mice were fed a high-fat diet and allowed free access to tea infusion (1:30, w/v) for 25 days, only yellow tea significantly reduced blood glucose. Therefore, various teas showed different safety profiles as well as anti-hyperglycemic efficacy strengths. To achieve an effective and safe anti-hyperglycemic outcome, yellow tea, which effectively suppressed high-fat diet-induced early elevation of hepatic thioredoxin-interacting protein, is an optimal choice.

Tsai WH, Wu CH, Yu HJ, Chien CT. l-Theanine inhibits proinflammatory PKC/ERK/ICAM-1/IL-33 signaling, apoptosis, and autophagy formation in substance P-induced hyperactive bladder in rats. Neurourol Urodyn 2016; 36:297-307. [PMID: 26828717 DOI: 10.1002/nau.22965] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2015] [Accepted: 01/15/2016] [Indexed: 12/13/2022]
Abstract
AIMS Upregulation of substance P (SP) and neurokinin-1 receptor (NK1R) activation induces pro-inflammatory bladder hyperactivity through the PKC/ERK/NF-κB/ICAM-1/IL-33 signaling pathways to increase the leukocyte infiltration and adhesion leading to reactive oxygen species (ROS) production, autophagy, and apoptosis. l-Theanine is a unique non-protein-forming amino acid present in tea (Camellia sinensis [L.] O. Kuntze) with its antioxidant, anti-inflammatory, and relaxation effects to improve cognition, mood, gastric ulcer injury, and cerebral ischemia/reperfusion injury, and posttraumatic stress disorder. We explored the protective effect of l-theanine on SP-induced bladder hyperactivity. METHODS In urethane-anesthetized female Wistar rats, we explored the transcystometrogram, pelvic nerve activity, proinflammatory PKC/ERK/NF-κB/ICAM-1/IL-33 signaling, apoptosis-related Caspase 3/poly-(ADP-ribose)-polymerase (PARP), and autophagy-mediated LC3 II expression by Western blot, electrophoretic-mobility shift assay and immunohistochemistry, bladder ROS amount by a ultrasensitive chemiluminescence method, and possible ROS sources from the different leukocytes by specific stains in SP-evoked hyperactive bladder. RESULTS l-Theanine dose-dependently depressed H2 O2 and HOCl activity in vitro. In urethane-anesthetized female Wistar rats, intra-arterial SP through NK1R activation increased voiding frequency (shortened intercontraction intervals) associated with the increase in bladder nerve activity, proinflammatory PKC/ERK/NF-κB/ICAM-1/IL-33 signaling, Caspase 3/PARP-mediated apoptosis, LC3 II-mediated autophagy, ROS amount, neutrophils adhesion, CD68 (monocyte/macrophage) infiltration, and mast cells degranulation in the hyperactive bladder. Intragastrical l-theanine (15 mg/kg) twice daily for 2 weeks efficiently ameliorated all the enhanced parameters in the SP-treated hyperactive bladder. CONCLUSIONS In conclusion, l-theanine through antioxidant and anti-inflammatory actions ameliorates SP-induced bladder hyperactivity via the inhibition of proinflammatory PKC/ERK/NF-κB/ICAM-1/IL-33 signaling, oxidative stress, bladder nerve hyperactivity, apoptosis, and autophagy.
