Chemotherapy-induced side effects affect the quality of life and efficacy of treatment of cancer patients. Current approaches for treating the side effects of chemotherapy are poorly effective and may cause numerous harmful side effects. Therefore, developing new and effective drugs derived from natural nontoxic compounds for the treatment of chemotherapy-induced side effects is necessary. Experiments in vivo and in vitro indicate that Panax ginseng (PG) and its ginsenosides are undoubtedly non-toxic and effective options for the treatment of chemotherapy-induced side effects, such as nephrotoxicity, hepatotoxicity, cardiotoxicity, immunotoxicity, and hematopoietic inhibition. The mechanism focus on anti-oxidation, anti-inflammation, and anti-apoptosis, as well as the modulation of signaling pathways, such as nuclear factor erythroid-2 related factor 2 (Nrf2)/heme oxygenase-1 (HO-1), P62/keap1/Nrf2, c-jun Nterminal kinase (JNK)/P53/caspase 3, mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinases (ERK), AMP-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR), mitogen-activated protein kinase kinase 4 (MKK4)/JNK, and phosphatidylinositol 3-kinase (PI3K)/AKT. Since a systemic review of the effect and mechanism of PG and its ginsenosides on chemotherapy-induced side effects has not yet been published, we provide a comprehensive summarization with this aim and shed light on the future research of PG.
Objectives The purpose of this study was to evaluate the effects of Curcumae Longae Rhizoma pharmacopuncture on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods Osteoarthritis was induced by injection of MIA ($50{\mu}L$ with 80 mg/mL) into knee joint cavity of rats. Rats were divided into 6 groups. Normal group was injected by normal saline into knee joint cavity only. Control group was induced for osteoarthritis by MIA and orally administered with distilled water. Normal Saline group was induced for osteoarthritis by MIA and injected with normal saline $100{\mu}L$. Positive comparison group was injected with MIA and orally administered with indomethacin 5 mg/kg. Curcumae Longae Rhizoma pharmacopuncture low concentration (CL) group was induced for osteoarthritis by MIA and injected with Curcumae Longae Rhizoma pharmacopuncture low concentration $100{\mu}L$. Curcumae Longae Rhizoma pharmacopuncture high concentration (CH) group was induced for osteoarthritis by MIA and injected with Curcumae Longae Rhizoma pharmacopuncture high concentration $100{\mu}L$. Curcumae Longae Rhizoma pharmacopuncture was injected at ST35 and EX-LE4 each group (CL, CH). After that, hind paw weight distribution was measured and oxidative stress biomarker in serum, liver function biomarker in serum, western blot analysis were measured. Histological analysis of knee joint tissue was performed by hematoxylin and eosin staining, Safranin-O staining and Masson's trichrome staining. Results Hind paw weight distribution was significantly improved in both group. alanine aminotransferanse and aspartate aminotransferase were decreased significantly in CH group compare with Indomethacin threated group. Antioxidant enzyme glutathione peroxidase, Catalase and heme oxygenase-1 were increased in CH group compare with control group. Inflammatory cytokine cyclooxygenase-2, inducible nitric oxide synthase and interleukin-1 beta were decreased significantly in CH group. Histological analysis result shows that protective effects of joint and cartilage were observed in both CH and CL groups in a concentration-dependent.

BACKGROUND/OBJECTIVE: The honeysuckle berry (HB) contains ascorbic acid and phenolic components, especially anthocyanins, flavonoids, and low-molecular-weight phenolic acids. In order to examine the potential of HB as a hepatoprotective medicinal food, we evaluated the in vitro anti-oxidant and anti-inflammatory activities of Korean HB (HBK) and Chinese HB (HBC). MATERIALS/METHODS: Antioxidant and anti-inflammatory effects of the extracts were examined in HepG2 and RAW 264.7 cells, respectively. The anti-oxidant capacity was determined by DPPH, SOD, CAT, and ARE luciferase activities. The production of nitric oxide (NO) as an inflammatory marker was also evaluated. The Nrf2-mediated mRNA levels of heme oxygenase-1 (HO-1), NAD(P)H dehydrogenase [quinone] 1 (Nqo1), and glutamate-cysteine ligase catalytic subunit (Gclc) were measured. The concentrations of HB extracts used were 3, 10, 30, 100, and $300{\mu}g/mL$. RESULTS: The radical scavenging activity of all HB extracts increased in a concentration-dependent manner (P < 0.01 or P < 0.05). SOD (P < 0.05) and CAT (P < 0.01) activities were increased by treatment with $300{\mu}g/mL$ of each HB extract, when compared to those in the control. NO production was observed in cells pretreated with 100 or $300{\mu}g/mL$ of HBC and HBK (P < 0.01). Treatment with $300{\mu}g/mL$ of HBC significantly increased Nqo1 (P < 0.01) and Gclc (P < 0.05) mRNA levels compared to those in the control. Treatment with $300{\mu}g/mL$ of HBK (P < 0.05) and HBC (P < 0.01) also significantly increased the HO-1 mRNA level compared to that in the control. CONCLUSIONS: Thus, the Korean and Chinese HBs were found to possess favorable in vitro anti-oxidant and anti-inflammatory activities. Nrf2 and its related anti-oxidant genes were associated with both anti-oxidant and anti-inflammatory activities in HB-treated cells. Further studies are needed to confirm these in vivo effects.
Nelumbo nucifera, also known as sacred lotus, has mainly been used as a food throughout the Asian countries. In the present study, we prepared ethanol extracts from leaf (NL), seed (NS), and seedpod (NSP) of Nelumbo nucifera and investigated their anti-inflammatory activities in mouse macrophage RAW 264.7 cells. To evaluate the anti-inflammatory activities of NL, NS, and NSP, nitric oxide (NO) production was measured in LPS-stimulated RAW 264.7 cells. NL, NS, and NSP significantly reduced NO production in a dose-dependent manner without affecting cell viabilities. NL, NS, and NSP dramatically decreased the protein expression of pro-inflammatory genes such as iNOS and COX-2. NL, NS, and NSP also suppressed phosphorylation of MAPKs and the nuclear translocation of $NF-{\kappa}B$ p65 indicating they have their anti-inflammatory activities via regulating mitogen-activated protein kinases (MAPKs) and nuclear factor kappa B ($NF-{\kappa}B$) pathways. In addition, we analyzed the production of reactive oxygen species (ROS) by the treatment of NL, NS, and NSP. All extracts reduced ROS production in a dose-dependent manner. And also, they increased heme oxygenase-1 (HO-1) protein expression and the nuclear translocation of nuclear respiratory factor 2 (Nrf2). In conclusion, our results suggest that Nelumbo nucifera has its anti-inflammatory activity via regulating MAPKs, $NF-{\kappa}B$, and Nrf2/HO-1 pathways.
The aim of this study was to investigate the effects of red ginseng-derived non-saponin fraction (NSF) on inflammatory responses and monocyte-to-macrophage differentiation in RAW264.7 and THP-1. NSF effectively inhibited inflammatory responses by downregulating nitric oxide (NO) production and protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). NSF ($2000{\mu}g/mL$) decreased the levels of NO, iNOS, and COX-2 by 33, 83, and 64%, respectively. NSF inhibited the differentiation of monocyte-to-macrophage by decreasing cell adherence along with downregulation of the cluster of differentiation molecule $11{\beta}$ ($CD11{\beta}$) and CD36. In addition, pro-inflammatory cytokines, such as tumor necrosis factor-alpha, interleukin 6, and monocyte chemoattractant protein 1 (MCP-1), were significantly reduced with NSF treatment. The NSF-mediated inhibition of inflammatory responses was due to the regulation of nuclear factor kappa-light-chain-enhancer of activated B cells ($NF-{\kappa}B$) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2). NSF effectively suppressed the translocation of $NF-{\kappa}B$ into the nucleus, while nuclear Nrf2 and its target protein, heme oxygenase-1, levels were significantly increased.
Aster yomena (Kitam.) Honda is an edible vegetable and perennial herb belonging to the Asteraceae family, and has been used for a long time for the prevention and treatment of various diseases. Although leaf extracts of A. yomena are known to have antioxidant and anti-inflammatory effects, accurate efficacy assessments are still inadequate. In this study, we investigated whether the antioxidant efficacy of ethanol extract of A. yomena leaf (EEAY) is correlated with the anti-inflammatory effect in RAW 264.7 macrophages. The results showed that EEAY significantly inhibited the hydrogen peroxide ($H_2O_2$)-induced growth inhibition in RAW 264.7 cells, which was associated with increased expression of nuclear factor erythroid 2-related factor-2 (Nrf2) and heme oxygenase-1 (HO-1). EEAY pretreatment also effectively prevented $H_2O_2$-induced reactive oxygen species generation and apoptosis through inhibition of caspase-3 activation and poly (ADP-ribose) polymerase degradation. Additionally, EEAY significantly increased the expression and production of interleukin-10, a representative anti-inflammatory cytokine, which was associated with increased expression of toll-like receptor 4 and myeloid differentiation factor 88 at transcriptional and translational levels. Furthermore, the increased production of nitric oxide (NO) by lipopolysaccharide was markedly abolished under the condition of EEAY pretreatment, and the inhibitory effect of NO production by EEAY was further increased by hemin, an HO-1 inducer. Overall, our results suggest that EEAY is able to activate the Nrf2/HO-1 signaling pathway to protect RAW 264.7 macrophages from oxidative and inflammatory stress.

Inflammatory and oxidative stimuli play a critical role not only in the process of transforming normal cells into cancer cells, but also in the proliferation process of cancer cells. Sipyukmiryukieum (SYMRKU), a traditional Korean herb-combined remedy, is composed of 16 kinds of herbal medicines, which were recorded for "Ongjeo" treatment in "Dongeuibogam". In this study, we investigated the inhibitory effect of SYMRKU against inflammatory and oxidative responses in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Our results showed that SYMRKU significantly inhibited LPS-induced secretion of pro-inflammatory mediators including nitric oxide (NO) and prostaglandin $E_2$ without showing any significant cytotoxicity. Consistent with these results, SYMRKU down-regulated LPS-induced expression of their regulatory enzymes such as inducible NO synthase and cyclooxygenase-2. SYMRKU also inhibited LPS-induced production and expression of pro-inflammatory cytokines such as tumor necrosis factor-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-6. In addition, SYMRKU significantly reduced the production of reactive oxygen species by LPS and showed a strong, which was associated with induction of nuclear factor erythroid 2-related factor 2 and heme oxygenase-1 expression. Although further studies are needed to fully understand the anti-inflammatory effects associated with the antioxidant capacity of SYMRKU, the findings of the current study suggest that SYMRKU may have potential benefits by inhibiting the onset and/or treatment of inflammatory and/or oxidative diseases.

In the present study, we prepared hot water extracts of green apple (GAHW) and unripe apple (UAHW), and ethanol extract of green apple (GAE), and investigated their anti-inflammatory activities in LPS-activated RAW264.7 cells. All extracts dramatically suppressed nitric oxide (NO) production in a dose-dependent manner in LPS-stimulated RAW264.7 cells without affecting cell viability. In addition, all extracts decreased the expression of iNOS, whereas UAHW only reduced the expression of COX-2. All extracts suppressed the phosphorylation of MAPKs (p38, ERK, and JNK) indicating all extracts show their anti-inflammatory activities via regulating MAPK pathway. Furthermore, all extracts reduced the production of reactive oxygen species in a dose-dependent manner and they increased the expression of heme oxygenase-I (HO-I) whereas UAHW could not. We also investigated whether apple flavonoids phloretin and phloridzin can have their anti-inflammatory activities in same in vitro model. Phloretin dramatically decreased NO production in a dose dependent manner without affecting cell viability, whereas phloridzin have no effects. Phloretin also reduced the expression of iNOS as well as COX-2, whereas phloridzin could not. Overall, these results suggest that apple extracts have their anti-inflammatory activities via regulating MAPKs and HO-1 pathways, and apple flavonoid phloretin can be one of phytochemicals responsible for anti-inflammatory effect of apple.
Benzo[a]pyrene (B[a]P) is a polycyclic aromatic hydrocarbon and ubiquitous environmental toxin with known harmful effects to human health. Abnormal phenotypes of keratinocytes are closely associated with their exposure to B[a]P. Resorcinol is a component of argan oil with reported anticancer activities, but its mechanism of action and potential effect on B[a]P damage to the skin is unknown. In this study, we investigated the effects of resorcinol on B[a]P-induced abnormal keratinocyte biology and its mechanisms of action in human epidermal keratinocyte cell line HaCaT. Resorcinol suppressed aryl hydrocarbon receptor (AhR) activity as evidenced by the inhibition of B[a]P-induced xenobiotic response element (XRE)-reporter activation and cytochrome P450 1A1 (CYP1A1) expression. In addition, resorcinol attenuated B[a]P-induced nuclear translocation of AhR, and production of ROS and pro-inflammatory cytokines. We also found that resorcinol increased nuclear factor (erythroid-derived 2)-like 2 (Nrf2) activity. Antioxidant response element (ARE)-reporter activity and expression of ARE-dependent genes NAD(P)H dehydrogenase [quinone] 1 (NQO1), heme oxygenase-1 (HO-1) were increased by resorcinol. Consistently, resorcinol treatment induced nuclear localization of Nrf2 as seen by Western analysis. Knockdown of Nrf2 attenuated the resorcinol effects on ARE signaling, but knockdown of AhR did not affect resorcinol activation of Nrf2. This suggests that activation of antioxidant activity by resorcinol is not mediated by AhR. These results indicate that resorcinol is protective against effects of B[a]P exposure. The mechanism of action of resorcinol is inhibition of AhR and activation of Nrf2-mediated antioxidant signaling. Our findings suggest that resorcinol may have potential as a protective agent against B[a]P-containing pollutants.
Atractylodes macrocephala is a perennial herb and is a member of the Compositae family. This plant is known to contain various bioactive constituents indicating anti-inflammatory, neuroprotective, anti-oxidant, immunological enhancement, and gastroprotective effects. In this investigation, we isolated four compounds with similar chemical structures from A. macrocephala, and evaluated their anti-inflammatory effects. Among the four compounds, compound 2(atractylenolide II) showed the second-best inhibitory effect on the lipopolysaccharide(LPS)-induced production of nitric oxide in RAW264.7 macrophages and BV2 microglial cells. Compound 2 also inhibited the LPS-induced the production of prostaglandin E2(PGE2), and the expression of inducible nitric oxide synthase(iNOS) and cyclooxygenase(COX)-2 proteins in both cells. In addition, compound 2 suppressed the production of pro-inflammatory cytokines including interleukin(IL)-1β, IL-6, and tumor necrosis factor(TNF)-α. These inhibitory effects were contributed by inactivation of nuclear factor kappa B(NF-κB) and mitogen-activated protein kinases(MAPKs) pathways by treatment with compound 2. This compound did not induce the expression of heme oxygenase(HO)-1 protein indicating that the anti-inflammatory effect of compound 2 was independent with HO-1 protein. Taken together, these results suggested that atractylenolide II can be a candidate material to treat inflammatory diseases.
