Abstract
Background Breast cancer (BC) is one of the most frequently observed malignancies globally, yet drug development for BC has been encountering escalating challenges. Commiphora myrrha is derived from the dried resin of C. myrrha (T. Nees) Engl., and is widely adopted in China for treating BC. However, the anti-BC effect and underlying mechanism of C. myrrha remain largely unclear. Methods MTT assay, EdU assay, and colony formation were used to determine the effect of C. myrrha n-hexane extract (CMHE) on the proliferation of human BC cells. Cell cycle distribution and apoptosis were assessed via flow cytometry analysis. Moreover, metastatic potential was evaluated using wound-scratch assay and matrigel invasion assay. The 4T1 breast cancer-bearing mouse model was established to evaluate the anti-BC efficacy of CMHE in vivo. RNA-sequencing analysis, quantitative real-time PCR, immunoblotting, immunohistochemical analysis, RNA interference assay, and database analysis were conducted to uncover the underlying mechanism of the anti-BC effect of CMHE. Results We demonstrated the significant inhibition in the proliferative capability of BC cell lines MDA-MB-231 and MCF-7 by CMHE. Moreover, CMHE-induced G0/G1 phase arrest and apoptosis of the above two BC cell lines were also observed. CMHE dramatically repressed the metastatic potential of these two cells in vitro. Additionally, the administration of CMHE remarkably suppressed tumor growth in 4T1 tumor-bearing mice. No obvious toxic or side effects of CMHE administration in mice were noted. Furthermore, immunohistochemical (IHC) analysis demonstrated that CMHE treatment inhibited the proliferative and metastatic abilities of cancer cells, while also promoting apoptosis in the tumor tissues of mice. Based on RNA sequencing analysis, quantitative real-time PCR, immunoblotting, and IHC assay, the administration of CMHE downregulated Cyclin D1/CDK4-Rb signaling pathway in BC. Furthermore, RNA interference assay and database analysis showed that downregulated Cyclin D1/CDK4 signaling cascade participated in the anti-BC activity of CMHE. Conclusion CMHE treatment resulted in the suppression of BC cell growth through the stimulation of cell cycle arrest at the G0/G1 phase and the induction of apoptotic cell death via the inhibition of the Cyclin D1/CDK4-Rb pathway, thereby enhancing the anti-BC effect of CMHE. CMHE has potential anti-BC effects, particularly in those harboring aberrant activation of Cyclin D1/CDK4-Rb signaling.

Abstract
Although vaccines are available for SARS-CoV-2, antiviral drugs such as nirmatrelvir are still needed, particularly for individuals in whom vaccines are less effective, such as the immunocompromised, to prevent severe COVID-19. Here we report an α-ketoamide-based peptidomimetic inhibitor of the SARS-CoV-2 main protease (Mpro), designated RAY1216. Enzyme inhibition kinetic analysis shows that RAY1216 has an inhibition constant of 8.4 nM and suggests that it dissociates about 12 times slower from Mpro compared with nirmatrelvir. The crystal structure of the SARS-CoV-2 Mpro:RAY1216 complex shows that RAY1216 covalently binds to the catalytic Cys145 through the α-ketoamide group. In vitro and using human ACE2 transgenic mouse models, RAY1216 shows antiviral activities against SARS-CoV-2 variants comparable to those of nirmatrelvir. It also shows improved pharmacokinetics in mice and rats, suggesting that RAY1216 could be used without ritonavir, which is co-administered with nirmatrelvir. RAY1216 has been approved as a single-component drug named 'leritrelvir' for COVID-19 treatment in China.

Abstract
Essential oils have many important biological properties, including antibacterial and antibiofilm activities. These unique properties make, essential oils good alternatives to synthetic chemical drugs, which have many side effects. In this study, we aimed to determine the chemical composition and biological activity of the essential oil obtained from Scutellaria brevibracteata subsp. brevibracteata. Specifically, its antibiofilm activity against Pseudomonas aeruginosa PAO1 and Staphylococcus aureus ATCC 29213 biofilms using XTT assay. Cytotoxic and apoptotic properties of the essential oil were investigated in human lung cancer cells (A540 and H1299) using MTT assay, Annexin V-FITC and propidium iodide staining and q-PCR. Thirty-two different compounds were identified from the essential oil, of which elemol (20.42 %), γ-eudesmol (20.12 %) and β-eudesmol (14.85 %) were the main components. The essential oil was more effective against P. aeruginosa PAO1 biofilm (79 %) than S. aureus ATCC 29213 biofilm (27 %). The specific activity of the essential oil against P. aeruginosa biofilm may be related to its high terpene contents. In addition, the essential oil showed high cytotoxic activity towards A549 (IC50 9.09 μg/ml) and H1299 (IC50 55.04 μg/ml) cell lines, inducing apoptosis in these cancer cells. These results demonstrate the antibiofilm and anticancer activities of S. brevibracteata subsp. brevibracteata essential oil.

Abstract
BACKGROUND Lung cancer is one of the leading causes of cancer-related deaths worldwide. Platycodin D (PD), a major pharmacological constituent from the Chinese medicinal herb named Platycodonis Radix, has shown potent anti-tumor activity. Also, it is also reported that PD could inhibit cellular growth in the non-small-cell lung carcinoma (NSCLC) A549 cell line. However, the underlying mechanism is not fully clarified. METHODS Cell proliferation was measured by MTT assay. Annexin V and propidium iodide (PI) assay were employed to study the apoptosis effects of PD on A549 cells. Western blot analysis was used to evaluate protein expression. Also, we used a siRNA against p53, as well as a plasmid-based RRM1 over-expression to investigate their functions. RESULTS It demonstrated PD inhibited A549 cell proliferation in a dose- and time-dependent manner. Further investigations showed that PD induced cell apoptosis, which was supported by dose-dependent and time-dependent caspase-3 activation and p53/VEGF/MMP2 pathway regulation. Also, PD demonstrated the inhibition effect of ribonucleotide reductase M1 (RRM1), whose role in various tumors is contradictory. Remarkably, in this work, RRM1 overexpression in A549 cells could have a negative impact on the regulation of the p53/VEGF/MMP2 pathway induced by PD treatment. Note as well that RRM1 overexpression also attenuated cell apoptosis and inhibition of cell proliferation of A549 treated with PD. CONCLUSION The results suggested that PD could inhibit A549 cell proliferation and induce cell apoptosis by regulating p53/VEGF/MMP2 pathway, in which RRM1 plays an important role directly.

Effect of Jinzhen granule on two coronaviruses: The novel SARS-CoV-2 and the HCoV-229E and the evidences for their mechanisms of action. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 95:153874.

Abstract
BACKGROUND Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and human coronavirus 229E (HCoV-229E) pose a huge threat to human public health, no specific treatment is available. Jinzhen granule (JZ) is a traditional eight ingredients-Chinese medicine with prominent efficacy for treating viral-induced diseases. However, little is known about the antiviral effect and mechanism of JZ against SARS-CoV-2 and HCoV-229E. PURPOSE This study aimed to reveal the antiviral effects of JZ against SARS-CoV-2 and HCoV-229E, and to further explore the underlying mechanisms regulating the host immune response. METHODS The chromatographic separation of JZ was performed using a Shimadzu analytical high-performance liquid chromatograph with UV detection and Alltech ELSD 2000ES. We conducted cytopathic effect (CPE) and plaque reduction assays to evaluate the antiviral effect of JZ. A lethal human angiotensin converting enzyme 2 (hACE2) transgenic mouse model of SARS-CoV-2 was established to determine the protective effect of JZ on mortality and lung virus titers. Real-time quantitative PCR assays were used to analyze the expression of proinflammatory cytokines in vitro and in vivo. Western blotting was further performed to determine the activities on regulating the nuclear factor kappa B (NF-κB)/MAPK pathway. Finally, mitochondrial membrane potential assays, flow cytometry analysis and western blotting were used to assess the anti-apoptotic potency toward HCoV-229E infection. RESULTS The results showed that 13 chemical components were identified and five peaks were determined and quantitated (gallic acid 1.97 mg/g, baicalin 20.69 mg/g, glycyrrhizic acid 4.92 mg/g, hyodeoxycholic acid 4.86 mg/g, cholic acid 4.07 mg/g). We found that JZ exerted inhibitory potency against SARS-CoV-2 and HCoV-229E in vitro by using CPE and plaque reduction assays, and it was further found that JZ protected mice infected by SARS-CoV-2 from death and inhibited lung virus titers. JZ also significantly decreased the induction of inflammatory cytokines (IL-1α, IL-6, CCL-5 and MIP-1β), similar to the observed in vitro effect. Moreover, JZ suppressed the release of inflammatory cytokines in vitro and it decreased the protein expression of p-p38 MAPK, p-JNK, p-NF-κB p65 and p-IκBα induced by HCoV-229E and increased the expression of IκBα. Notably, JZ significantly protected HCoV-229E-infected Huh-7 cells from mitochondrial damage and decreased apoptotic cells. The activation of the mitochondria-mediated apoptotic pathway was inhibited by JZ, as shown by the reduced expression of cleaved caspase-9, caspase-3 and p-PARP. CONCLUSIONS In conclusion, JZ (gallic acid 1.97 mg/g, baicalin 20.69 mg/g, glycyrrhizic acid 4.92 mg/g, hyodeoxycholic acid 4.86 mg/g, cholic acid 4.07 mg/g) exhibited antiviral activities against SARS-CoV-2 and HCoV-229E by regulating the NF-κB/MAPK pathway and the mitochondria-mediated apoptotic pathway. These findings demonstrated the efficacy of JZ against CoVs and suggested JZ treatment as a novel clinical therapeutic strategy for COVID-19.

Abstract
BACKGROUND Globally, lung cancer is the leading cause of cancer associated mortalities. The current conventional chemotherapy remains the preferred treatment option for lung cancer, as surgical resection plays little role in the treatment of over 75% of lung cancer patients. Therefore, there is a need to develop novel potential therapeutic drugs or adjuvants with a high efficiency and safety against lung cancer. Scutellaria baicalensis Georgi, a common Chinese medicinal herb that has been in use for more than 2000 years, has recently been shown to possess significant activities against lung cancer. However, current research progress on pharmacological effects and relevant molecular mechanisms of S. baicalensis in lung cancer therapy have not been systematically summarized. PURPOSE This review aimed at elucidating on the anti-lung cancer mechanisms and antitumor efficacies of S. baicalensis as well as its active ingredients, and providing a valuable reference for further investigation in this field. METHODS We used "Scutellaria baicalensis" or the name of the compound in S. baicalensis, in combination with "lung cancer" as key words to systematically search for relevant literature from the Web of Science and PubMed databases. Publications that investigated molecular mechanisms were the only ones selected for analysis. The PRISMA guidelines were followed. RESULTS Fifty-four publications met the inclusion criteria for this study. Five anti-lung cancer mechanisms of S. baicalensis and its constituent components are discussed. These mechanisms include apoptosis induction, cell-cycle arrest, suppression of proliferation, blockade of invasion and metastasis, and overcoming drug-resistance. These compounds exhibited high antitumor efficacies and safety against lung cancer xenografts. CONCLUSION Studies should aim at elucidating on the anti-cancer mechanisms of S. baicalensis to achieve the ultimate goal of lung cancer therapy.

[PMID: 34174375 PMCID: PMC8223030 DOI: 10.1016/j.jep.2021.114367] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 06/19/2021] [Accepted: 06/22/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Although the rapid emergence of coronavirus disease 2019 (COVID-19) poses a considerable threat to global public health, no specific treatment is available for COVID-19. ReDuNing injection (RDN) is a traditional Chinese medicine known to exert antibacterial, antiviral, antipyretic, and anti-inflammatory effects. In addition, RDN has been recommended in the diagnosis and treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated pneumonia by the National Health Council and the National Administration of Chinese Medicine. However, there is no information regarding its efficacy against COVID-19. AIM OF STUDY This study was designed to determine the clinical efficacy of RDN in patients with COVID-19 and characterize its antiviral activity against SARS-CoV-2 in vitro. MATERIALS AND METHODS A total of 50 adults with COVID-19 were included in this study, and the primary endpoint was recovery from clinical symptoms following 14 days of treatment. General improvements were defined as the disappearance of the major symptoms of infection including fever, fatigue, and cough. The secondary endpoints included the proportion of patients who achieved clinical symptom amelioration on days 7 and 10, time to clinical recovery, time to a negative nucleic acid test result, duration of hospitalization, and time to defervescence. Plaque reduction and cytopathic effect assays were also performed in vitro, and reverse-transcription quantitative PCR was performed to evaluate the expression of inflammatory cytokines (TNF-α, IP-10, MCP-1, IL-6, IFN-α, IFN-γ, IL-2 and CCL-5) during SARS-CoV-2 infection. RESULTS The RDN group exhibited a shorter median time for the resolution of clinical symptoms (120 vs. 220 h, P < 0.0001), less time to a negative PCR test result (215 vs. 310 h, P = 0.0017), shorter hospitalization (14.8 vs. 18.5 days, P = 0.0002), and lower timeframe for defervescence (24.5 vs. 75 h, P = 0.0001) than the control group. In addition, time to improved imaging was also shorter in the RDN group than in the control group (6 vs.8.9 days, P = 0.0273); symptom resolution rates were higher in the RDN group than in the control group at 7 (96.30% vs. 39.13%, P < 0.0001) and 10 days (96.30% vs. 56.52%, P = 0.0008). No allergic reactions or anaphylactic responses were reported in this trial. RDN markedly inhibited SARS-CoV-2 proliferation and viral plaque formation in vitro. In addition, RDN significantly reduced inflammatory cytokine production in infected cells. CONCLUSIONS RDN relieves clinical symptoms in patients with COVID-19 and reduces SARS-CoV-2 infection by regulating inflammatory cytokine-related disorders, suggestion that this medication might be a safe and effective treatment for COVID-19.

Abstract
The present work aimed to evaluate the reactivity of natural bioflavonoid hesperidin (HSP) and synthetically derived XAV939 (XAV) against human hepatocellular carcinoma (HepG2), human breast cancer (MDA-MB231) cancer cell lines, and related molecular and pathological profiles. Data recorded revealed that the cytotoxic potential of the tested products was found to be cell type- and concentration-dependent. The half-maximal inhibitory concentration (IC50) value of the HSP-XAV mixture against MDA-MB231 was significantly decreased in the case of using the HSP-XAV mixture against the HepG2 cell line. Also, there was a significant upregulation of the phosphotumor suppressor protein gene (P53) and proapoptotic genes such as B-cell lymphoma-associated X-protein (Bax, CK, and Caspase-3), while antiapoptotic gene B-cell lymphoma (Bcl-2) was significantly downregulated compared with the untreated cell control. The cell cycle analysis demonstrated that DNA accumulation was detected mainly during the G2/M phase of the cell cycle accompanied with the elevated reactive oxygen species level in the treatment of HepG2 and MDA-MB231 cell lines by the HSP-XAV mixture, more significantly than that in the case of cell control. Finally, our finding suggests that both HSP and XAV939 and their mixture may offer an alternative in human liver and breast cancer therapy.

RN181 regulates the biological behaviors of oral squamous cell carcinoma cells via mediating ERK/MAPK signaling pathway. Acta Histochem 2021; 123:151733. [PMID: 34052676 DOI: 10.1016/j.acthis.2021.151733] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 05/12/2021] [Accepted: 05/15/2021] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To explore the role of RN181 in the pathogenesis of oral squamous cell carcinoma (OSCC) cells via mediating ERK/MAPK signaling. METHODS The expression of RN181 was detected in OSCC tissues and cells. CAL27 and SCC-15 cells were divided into Control, Empty, RN181, si-RN181, U0126 (an inhibitor of ERK/MAPK pathway) and si-RN181 + U0126 groups. MTT was used to determine cell proliferation, flow cytometry to determine cell cycle and apoptosis, Transwell assay and wound healing test to determine cell invasion and migration, respectively. Western blotting was used to measure the protein expression. Furthermore, a xenograft tumor model was established to observe the effect of RN181 on the in vivo growth of OSCC cells. RESULTS RN181 was down-regulated in OSCC tissues and cells. As compared to the Control group, CAL27 and SCC-15 cells in the RN181 group and U0126 group presented with decreases in the proliferation, invasion and migration, but increases in the cell ratio at the G0/G1 phase and apoptosis, while the p-ERK 1/2/ERK 1/2 was down-regulated. Cells in the si-RN181 group manifested the opposite changes. U0126 could reverse the positive effect of si-RN181 on the growth of OSCC cells. In vivo experiment demonstrated that the tumor growth and weight were reduced in the RN181 group, with decreased Ki67 positive expression and elevated TUNEL positive cells. CONCLUSION RN181 was down-regulated in OSCC, and it could inhibit the proliferation, invasion and migration, cause the G0/G1 arrest, while promote the apoptosis of OSCC cells via inhibiting ERK/MAPK pathway.

Abstract
Flavonoids as the largest group of natural phytochemical compounds have received significant attention, as demonstrated by clinical trials, due to their chemotherapeutic and/or pharmacological effects against non-small-cell lung cancer (NSCLC) and asthma. Scutellaria baicalensis (S. baicalensis), known as one of the most popular medicinal plants and used in several countries, contains natural active flavone constituents, with the major compounds of the roots being baicalein, baicalin, wogonin, wogonoside and oroxylin A. S. baicalensis and their compounds are proven to have inhibitory effects on NSCLC cells when used at different concentrations. However, the exact mechanisms by which these compounds exert their therapeutic effects against asthma remain unexplored. Indeed, the mechanisms by which S. baicalensis and its flavone compounds exert a protective effect against nicotine-induced NSCLC and asthma are not yet fully understood. Therefore, this review explores the mechanisms involved in the therapeutic potential of flavone-rich extracts from S. baicalensis in nicotine-induced NSCLC and asthma.

The Root Extract of Scutellaria baicalensis Induces Apoptosis in EGFR TKI-Resistant Human Lung Cancer Cells by Inactivation of STAT3. Int J Mol Sci 2021; 22:ijms22105181. [PMID: 34068421 PMCID: PMC8153615 DOI: 10.3390/ijms22105181] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 05/03/2021] [Accepted: 05/10/2021] [Indexed: 12/20/2022] Open
Abstract
Resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) is a major obstacle in managing lung cancer. The root of Scutellaria baicalensis (SB) traditionally used for fever clearance and detoxification possesses various bioactivities including anticancer effects. The purpose of this study was to investigate whether SB exhibited anticancer activity in EGFR TKI-resistant lung cancer cells and to explore the underlying mechanism. We used four types of human lung cancer cell lines, including H1299 (EGFR wildtype; EGFR TKI-resistant), H1975 (acquired TKI-resistant), PC9/ER (acquired erlotinib-resistant), and PC9/GR (acquired gefitinib-resistant) cells. The ethanol extract of SB (ESB) decreased cell viability and suppressed colony formation in the four cell lines. ESB stimulated nuclear fragmentation and the cleavage of poly(ADP-ribose) polymerase (PARP) and caspase-3. Consistently, the proportion of sub-G1 phase cells and annexin V+ cells were significantly elevated by ESB, indicating that ESB induced apoptotic cell death in EGFR TKI-resistant cells. ESB dephosphorylated signal transducer and activator of transcription 3 (STAT3) and downregulated the target gene expression. The overexpression of constitutively active STAT3 reversed ESB-induced apoptosis, suggesting that ESB triggered apoptosis in EGFR TKI-resistant cells by inactivating STAT3. Taken together, we propose the potential use of SB as a novel therapeutic for lung cancer patients with EGFR TKI resistance.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has extensively and rapidly spread in the world, causing an outbreak of acute infectious pneumonia. However, no specific antiviral drugs or vaccines can be used. Phillyrin (KD-1), a representative ingredient of Forsythia suspensa, possesses anti-inflammatory, anti-oxidant, and antiviral activities. However, little is known about the antiviral abilities and mechanism of KD-1 against SARS-CoV-2 and human coronavirus 229E (HCoV-229E). PURPOSE The study was designed to investigate the antiviral and anti-inflammatory activities of KD-1 against the novel SARS-CoV-2 and HCoV-229E and its potential effect in regulating host immune response in vitro. METHODS The antiviral activities of KD-1 against SARS-CoV-2 and HCoV-229E were assessed in Vero E6 cells using cytopathic effect and plaque-reduction assay. Proinflammatory cytokine expression levels upon infection with SARS-CoV-2 and HCoV-229E infection in Huh-7 cells were measured by real-time quantitative PCR assays. Western blot assay was used to determine the protein expression of nuclear factor kappa B (NF-κB) p65, p-NF-κB p65, IκBα, and p-IκBα in Huh-7 cells, which are the key targets of the NF-κB pathway. RESULTS KD-1 could significantly inhibit SARS-CoV-2 and HCoV-229E replication in vitro. KD-1 could also markedly reduce the production of proinflammatory cytokines (TNF-α, IL-6, IL-1β, MCP-1, and IP-10) at the mRNA levels. Moreover, KD-1 could significantly reduce the protein expression of p-NF-κB p65, NF-κB p65, and p-IκBα, while increasing the expression of IκBα in Huh-7 cells. CONCLUSIONS KD-1 could significantly inhibit virus proliferation in vitro, the up-regulated expression of proinflammatory cytokines induced by SARS-CoV-2 and HCoV-229E by regulating the activity of the NF-кB signaling pathway. Our findings indicated that KD-1 protected against virus attack and can thus be used as a novel strategy for controlling the coronavirus disease 2019.

Abstract
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has spread worldwide through person-to-person contact, causing a public health emergency of international concern. At present, there is no specific antiviral treatment recommended for SARS-CoV-2 infection. Liu Shen capsule (LS), a traditional Chinese medicine, has been proven to have a wide spectrum of pharmacological properties, such as anti-inflammatory, antiviral and immunomodulatory activities. However, little is known about the antiviral effect of LS against SARS-CoV-2. Herein, the study was designed to investigate the antiviral activity of SARS-CoV-2 and its potential effect in regulating the host's immune response. The inhibitory effect of LS against SARS-CoV-2 replication in Vero E6 cells was evaluated by using the cytopathic effect (CPE) and plaque reduction assay. The number of virions of SARS-CoV-2 was observed under transmission electron microscope after treatment with LS. Proinflammatory cytokine expression levels upon SARS-CoV-2 infection in Huh-7 cells were measured by real-time quantitative PCR assays. The results showed that LS could significantly inhibit SARS-CoV-2 replication in Vero E6 cells, and reduce the number of virus particles and it could markedly reduce pro-inflammatory cytokines (TNF-α, IL-6, IL-1β, IL-8, CCL-2/MCP-1 and CXCL-10/IP-10) production at the mRNA levels. Moreover, the expression of the key proteins in the NF-κB/MAPK signaling pathway was detected by western blot and it was found that LS could inhibit the expression of p-NF-κB p65, p-IκBα and p-p38 MAPK, while increasing the expression of IκBα. These findings indicate that LS could inhibit SARS-CoV-2 virus infection via downregulating the expression of inflammatory cytokines induced virus and regulating the activity of NF-κB/MAPK signaling pathway in vitro, making its promising candidate treatment for controlling COVID-19 disease.

Ma Q, Huang W, Zhao J, Yang Z. Liu Shen Wan inhibits influenza a virus and excessive virus-induced inflammatory response via suppression of TLR4/NF-κB signaling pathway in vitro and in vivo. JOURNAL OF ETHNOPHARMACOLOGY 2020; 252:112584. [PMID: 31972325 DOI: 10.1016/j.jep.2020.112584] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Revised: 01/04/2020] [Accepted: 01/15/2020] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Liu Shen Wan (LSW), first prescribed in "Lei Yunshang Song Fen Tang Fang", traditional Chinese medicine (TCM), is used to cure influenza, tonsillitis, pharyngitis and mumps for more than one hundred years. AIM OF STUDY LSW was proved extensive pharmacological properties, for instance, anti-inflammatory, anticancer, antiviral, analgesic, antibacterial and immunomodulatory activities. Nevertheless, the mechanism of this process and the evaluation of this product is still ambiguous. Hence, the study was designed to investigate the antiviral and anti-inflammatory activities of LSW against the influenza virus in vitro and vivo. MATERIALS AND METHODS The antiviral activities of LSW were assayed in virus-infected cells and mice. To study the antiviral effects of LSW against influenza A/PR/8/34 virus (PR8), we employed CPE inhibition assay with different concentrations of LSW at different times of infection in vitro. The mice were intranasally infected with virus to induce viral pneumonia, then treated with different doses of LSW. The death protection of the mice, the lung index, virus titer and pathological changes in the lung tissue of mice were investigated to estimate the anti-virus effect of LSW. Moreover, RT-qPCR was used to determine the mRNA expression of TNF-α, IL-1β, IL-6, and IFN-γ in the A549 cells and the supernatant of lung tissues, and the concentrations of these four cytokines in serum of mice were determined with ELISA. Western blot was used to determine the expression of TLR4, p-NF-κB p65, NF-κB p65, p-IκBα and IκBα in the A549 cells and lung tissues, which are the key targets of TLR4/NF-κB pathway. Moreover, the immunohistochemical assay was used to determine the expression of the NF-κB p65 in the mice lungs. RESULTS LSW could significantly inhibit influenza virus at different stages of viral replication (at the process of the pre-, post-, and co-virus infection) in vitro. And LSW (100 mg/kg and 50 mg/kg) could effectively increase the survival time of mice. The virus titres, lung index, pathological changes in the mice lungs also decreased. Moreover, LSW could significantly reduce the contents of IL-1β, TNF-α, IFN-γ and IL-6 in the infected cells and the infected-mice. In addition, LSW could significantly reduce the expression of TLR4, p-NF-κB p65, NF-κB p65 and p-IκBα, while increase the IκBα in the infected cells and in the lung of mice. CONCLUSIONS LSW could significantly not only inhibit virus replication and proliferation in vitro, but also ameliorate pneumonia damage in vivo. The antiviral effect was attributed to down-regulating the expression of inflammatory cytokines induced by influenza virus via regulating the activity of TLR4/NF-кB signaling pathway.

Abstract
Scutellaria baicalensis (S. baicalensis) is a plant that is widely used for medicinal purposes. Baicalein, one of the primary bioactive compounds found in S. baicalensis, is thought to possess antitumor activity, although the specific mechanisms remain unclear. Therefore, the present study aimed to evaluate the ability of baicalein to disrupt the proliferation and metastatic potential of colorectal cancer (CRC) cells; a rapid and sensitive ultra-high performance liquid chromatography-tandem mass spectrometric method was employed for the identification of baicalein in an S. baicalensis aqueous extract and in rat plasma. To investigate the effects of baicalein, Cell Counting Kit-8 (CCK-8), western blotting, wound-healing and Transwell assays were performed. The data indicated that baicalein was absorbed into the blood and was able to effectively disrupt the proliferation, migration and invasion abilities of CRC cells in a dose- and time-dependent manner. Baicalein treatment was also revealed to decrease the expression of epithelial-mesenchymal transition (EMT)-promoting factors including vimentin, Twist1, and Snail, but to upregulate the expression of E-cadherin in CRC cells. The expression levels of cell cycle inhibitory proteins p53 and p21 also increased following baicalein treatment. In addition, Snail-induced vimentin and Twist1 upregulation, as well as E-cadherin downregulation, were reversed following treatment with baicalein. In conclusion, the results of the present study indicate that baicalein may suppress EMT, at least in part, by decreasing Snail activity.

Xu H, He L, Chen J, Hou X, Fan F, Wu H, Zhu H, Guo Y. Different types of effective fractions from Radix Isatidis revealed a multiple-target synergy effect against respiratory syncytial virus through RIG-I and MDA5 signaling pathways, a pilot study to testify the theory of superposition of traditional Chinese Medicine efficacy. JOURNAL OF ETHNOPHARMACOLOGY 2019; 239:111901. [PMID: 31051218 DOI: 10.1016/j.jep.2019.111901] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 04/16/2019] [Accepted: 04/19/2019] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix Isatidis, a commonly used traditional Chinese medicine, is also documented in "Dictionary of Chinese Ethnic Medicine" being as an ethnic herb clinically utilized by different nations in China such as Mongol, Uygur, and Dong et al. It has been reported to have a very strong efficacy on respiratory viruses, but to date the mechanism remains unknown. Similarly, it is unclear how different types of effective fractions of Radix Isatidis interact to exert antiviral effects. AIM OF STUDY To reveal the underlying mechanisms for the inhibitory effects of three active fractions from Radix Isatidis, i.e. total alkaloids, lignans and organic acids, on respiratory syncytial virus when used alone or in combination. In addition, we investigated whether these three parts worked synergistically in vivo and in vitro. MATERIALS AND METHODS A mouse model of RSV infection was constructed by intranasal infection, and the pathological changes of lung tissues in different parts were observed. The level changes of IFNβ and inflammatory cytokines in the mouse alveolar lavage fluid were detected by enzyme-linked immunosorbent assay (ELISA). The anti-RSV effects of different effective fractions were evaluated by the plaque reduction test. The mRNA and protein expressions of RIG-I, MDA-5, MAVS and IRF3 in RAW264.7 cells were detected by RT-PCR and Western blot respectively. RESULTS HE staining showed that Radix Isatidis extracts alone or in combination relieved virus-induced mouse lung lesions. Compared with individual drugs, the lung lesions were alleviated more significantly after treatment with the three fractions in combination. ELISA demonstrated that the expression levels of IFNβ and inflammatory cytokines were maintained balanced between antiviral and proinflammatory effects. The plaque reduction test indicated that the antiviral effect of combination treatment was much stronger than those of individual drugs. RT-qPCR and Western blot suggested that the mRNA and protein expression levels of key signaling molecules in the RIG-I and MDA5 pathways in mouse macrophages were down-regulated by different effective parts alone or in combination. CONCLUSIONS The three effective fractions of Radix Isatidis have remarkable synergistic anti-RSV effects in vitro and in vivo, and total alkaloids and lignans show multi-target synergistic effects via the RIG-I and MDA5 signaling pathways.

Abstract
Scutellaria Radix (SR) is an herb traditionally used in Asian countries to treat inflammatory diseases. Recent studies report that SR exhibits anticancer activities in various types of tumors. In this study, we investigated the apoptotic and autophagic effect of SR in non-small cell lung cancer (NSCLC), the leading cause of cancer-associated death. Treatment of SR in two NSCLC cell lines, H358 and H2087 cells resulted in suppressed cell viability. Western blot assays showed increased expressions of Bcl-2-associated X protein (Bax), cleaved-caspase 3 and cleaved-Poly ADP ribose polymerase (PARP), key factors of apoptosis. Co-treatment of SR with a caspase inhibitor Z-VAD led to nullification of the antiproliferative effect, suggesting the role of apoptosis in the action mechanism of SR. Further experiments revealed autophagy was involved in the effect of SR. SR-treated NSCLC cells expressed increased ratio of microtubule-associated protein 1A/1B-light chain 3 (LC3)-II/LC3-I. When chloroquine was co-treated with SR, this ratio was further increased, indicating SR treatment induced autophagy in NSCLC cells. Interestingly, loss of autophagy by 3-Methyladenine (3-MA) co-treatment suppressed SR-induced apoptosis. We then evaluated the relevance of AMP-activated protein kinase (AMPK) in the autophagic/apoptotic process in NSCLC by SR treatment. Immunoblot assays showed increased phosphorylation of AMPK α and P70-S6 kinase in SR-treated H358 and H2087 cells. Under AMPK-inhibited conditions by compound C, SR treatment failed to induce both autophagy and apoptosis. Taken together, this study identifies the positive effect of SR in H358 and H2087 cells by inducing apoptosis via AMPK-dependent autophagy. Thus, our results suggest the potential use of SR as a novel therapeutic strategy for NSCLC patients.

Abstract
The widespread use of plants as accessible anticancer agents leads to the identification of many natural source chemotherapeutic agents. Scutellaria one of the popular genus of flowering plants has been used for various human illnesses for thousands of years. Scutellaria has anti-metastatic, anti-proliferative, anti-invasion, anti-angiogenic and apoptosis effects in vitro as well as in vivo. Despite numerous reports on the cytotoxic-antitumor activity of the plant, there are still some issues need further consideration. Issues such as unjustified interpretations, lack of attention to the pharmacokinetics profile and weak study design may affect the final decision about the use of plants as anticancer agents and possibly needs reconsideration. In this review, we have summarized the potential health benefits of Scutellaria and its active components also the underlying mechanism of cytotoxicity and antitumor activity. Meanwhile we have discussed concerns may interfere with the precise conclusion.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Viscum articulatum Burm. f. (leafless mistletoe) has been used in traditional system of medicines in India, China, Taiwan, Cambodia, Laos, and Vietnam, to treat blood-related diseases and various inflammatory and degenerative diseases including cancer. Anticancer activities of some phytomolecules purified from Viscum articulatum Burm. f. have been tested. However scientific evidence for the anticancerous potential of aqueous extract of V. articularum (VAQE) used in traditional medicine is lacking. AIM OF THE STUDY To study the antiproliferative and apoptotic effect of VAQE on Jurkat E6.1 and THP1 leukemia cells. MATERIALS AND METHODS The aqueous extract of the whole plant of Viscum articulatum Burm. f. was prepared in phosphate buffer saline. In VAQE, total soluble protein was estimated using Bradford's dye-binding assay; flavonoid content was determined using aluminum chloride colorimetric assay; and phenolic content was estimated following Folin-Ciocalteu colorimetric assay. XTT cell viability assay was used to test VAQE induced cytotoxicity in Jurkat E6.1 and THP1 leukemia cells and peripheral blood mononuclear cells (PBMC). The effect of VAQE on cell cycle progression was analyzed by PI staining using flow cytometry. Annexin-V-FITC/PI differential staining method was used for detecting the onset of apoptosis in leukemia cells. Rhodamine 123 dye was used to detect the change in mitochondrial membrane potential (MMP) using flow cytometry. DCF-DA fluorescence dye was used to estimate the level of reactive oxygen species (ROS). The ROS inhibitors were used to evaluate the role of ROS in mediating DNA degradation in VAQE-treated leukemia cells. The molecular mechanisms underlying VAQE induced apoptosis induction was studied by analyzing the expression of anti-apoptotic (Bcl-2) and pro-apoptotic (Bax) proteins, caspase-8 and caspase-3 enzymes using western blot. Diphenylamine (DPA) assay was used to determine the DNA fragmentation and conclusion of apoptosis. RESULTS VAQE triggered cytotoxic effect on Jurkat E6.1 (IC50-2.4 µg/ml; 24 h) and THP1 (IC50-1.0 µg/ml; 24 h) cells in a dose- and time-dependent manner. The apoptosis induction and G2/M arrest of the cell cycle are the cause of VAQE-induced cytotoxicity in leukemia cells. The apoptosis in VAQE-treated Jurkat E6.1 and THP1 cells was mediated via a reduction in MMP, elevation of intracellular ROS, decreased expression of the anti-apoptotic (Bcl-2) and increased expression of the pro-apoptotic (Bax) protein, activation of caspase-8 and caspase-3 and DNA fragmentation. CONCLUSION VAQE has a high efficacy to exert a cytotoxic effect in Jurkat E6.1 and THP1 cells and to induce apoptosis and G2/M cell cycle arrest. VAQE induces extrinsic pathway of apoptosis in both the leukemia cell lines via disruption of MMP, intracellular ROS imbalance, increased ratio of Bax/Bcl-2, activation of caspase-8, caspase-3 and ROS-mediated DNA fragmentation. The knowledge gained from the outcomes of the study may encourage the identification of novel chemotherapeutic agent from Viscum articulatum Burm. f. to treat leukemia.

Abstract
Although the effect of Huaier has been widely studied, its role and its molecular mechanism in lung cancer are not clear. In this study, we explored the inhibitory effect of Huaier on lung cancer cells and its molecular mechanism. The cell viability, migration and invasion were analyzed by CCK-8 and BrdU cell proliferation assay kits, Transwell and colony forming assay. The cell cycle and apoptosis were analyzed by flow cytometry. The experimental results showed that the viability, migration and invasion of A549 and NCI-H1650 cells were inhibited by Huaier in a dose and time-dependent manner. Huaier induced cell apoptosis and the cells were blocked in the S phase to inhibit cell proliferation. Western blotting results showed that Huaier inhibited the expression of MTDH and increased the proportion of Bax/Bcl-2, it could also promote the expression of Cleaved Caspase-3 and increase the activity of Caspase-3, promote cell apoptosis and inhibit cell proliferation. Huaier inhibited the metastasis and invasion of lung cancer cells by inhibiting the expression levels of EMT related proteins, it also inhibited the expression of JAK2/STAT3 and MAPK signaling pathways. Therefore, our results showed that Huaier may inhibit the proliferation and metastasis of lung cancer cells through multiple targets, it had the potential for treatment of lung cancer.

The San Wu Huangqin Decoction (SWHD), a traditional Chinese medicine formula, is used to treat colds caused by exposure to wind-pathogen, hyperpyrexia, infectious diseases and cancer; moreover, it is used for detoxification. The individual herbs of SWHD, such as Sophora flavescens and Scutellaria baicalensis, exhibit a wide spectrum of antiviral, anti-inflammatory, antibacterial, anticancer and other properties. The Chinese compound formula of SWHD is composed of S. flavescens, S. baicalensis and Rehmannia glutinosa. However, the effect of SWHD on the influenza virus (IFV) and its mechanism remain unknown. The aim of this study was to evaluate, for the first time, whether SWHD could be used to treat influenza. Results showed that SWHD could effectively inhibit influenza A/PR/8/34 (H1N1) virus at different stages of viral replication (confirmed through antiviral effect assay, penetration assay, attachment assay and internalization assay) in vitro. It could reduce the infection of the virus in a dose- and time-dependent manner, as confirmed by observing the cell cytopathic effect and calculating the cell viability (p < 0.05). SWHD demonstrated better antiviral activity than oseltamivir in the evaluation of antiviral prophylaxis on influenza (p < 0.05). The antiviral activity of SWHD may be related to its regulation ability on the immune system. Western blot, real-time polymerase chain reaction and indirect immunofluorescence assay showed that the expression of the four target viral proteins of the IFV (namely, haemagglutinin (HA), neuraminidase (NA), nucleoprotein (NP) and matrix-2 (M2)) reduced significantly (p < 0.05). Moreover, SWHD (23.40 and 11.70 g/kg) significantly alleviated the clinical signs, reduced the mortality and increased the survival time of infected mice (p < 0.05). The lung index, virus titres, pathological changes in lung tissues and the expression of key proteins of the IFV in mice also decreased (p < 0.05). In conclusion, SWHD possessed anti-influenza activity. This work provided a new view of complementary therapy and drug discovery for clinical treatment.

Abstract
Scutellaria baicalensis (Huangqin in Chinese) is a major traditional Chinese medicine (TCM) herb, which has a long history of use in the treatment of a variety of symptoms correlated with cancer. In the past decade, the potential of S. baicalensis and single compounds derived from it as anticancer agents targeting various pathways has received extensive research attention. Specifically, the proliferation and metastases inhibiting properties of the single compounds in cancer have been studied; however, the underlying mechanisms remain unclear. This review summarizes the various mechanisms, pathways and molecular targets involved in the anticancer activity of S. baicalensis and its single compounds. However, the aim of this review is to provide a more thorough view of the last 10 years to link traditional use with modern research and to highlight recently discovered molecular mechanisms. Extracts and major flavonoids derived from S. baicalensis have been found to possess anticancer effects in multiple cancer cell lines both in vitro and in vivo. Further investigation is warranted to better understand the underlying mechanisms and to discover novel targets and cancer therapeutic drugs that may improve both the survival and quality of life of cancer patients.

Abstract
Phytoestrogens are polyphenol compounds which have similar structure to 17β-estradiol (E2), a kind of main estrogen in women. Thus, phytoestrogens may affect the reproductive and endocrine systems, leading to the development of estrogen-related cancers. The effect of genistein (Gen), one of the most studied phytoestrogens, on human cervical cancer cells (HeLa) was investigated in this study. It was found that Gen at concentrations of 0.001, 0.01, 0.1 and 1 µmol·L-1 promoted the proliferation of HeLa cells in a dose-dependent manner. Gen increased the portion of HeLa cells in S phase and decreased the portion of the cells in G1 phase. Besides, apoptosis rate of the cells was significantly lower when treated with Gen compared with the control group. It was also found that the expression of ERα, Akt or nuclear NF-κB p65 protein was activated by Gen. The correlation between these three proteins may be as following: ERα was the upstream, followed by Akt, and then nuclear NF-κB p65 protein. In addition, the downstream genes of activated nuclear NF-κB p65 were found to be associated with cell cycle and apoptosis of cancer cells. Our results suggested that Gen may stimulate cell proliferation partially through the estrogen receptor-mediated PI3K/Akt-NF-κB pathway and the further activation of the downstream genes of nuclear NF-κB p65.

Abstract
Gastric cancer is the fifth most common cancer and the third leading cause of cancer deaths worldwide. South Korea is in first place with 9,180 death alone attributed to gastric cancer in 2013. Plenty of literature suggests the evasion of apoptosis is implicated in neurodegeneration, autoimmune diseases, and tumors development due to dysregulation in the apoptotic mechanism. Reduced apoptosis or its resistance in cancer cells plays a significant role in carcinogenesis. It’s imperative to understand apoptosis, which provides the basis for novel targeted therapies that can induce cancer cell death or sensitize them to cytotoxic agents by regulating key factors like IAPs, MDM2, p53, caspases and much more. Studies have demonstrated that Scutellarein have the ability to inhibit several cancer cells by inducing apoptosis with both: Scutellarein monomers as well as scutellarein containing flavonoids. MTT results revealed that scutellarein inhibited cell viability in both dose and time dependent manner. Flow cytometry and western blot analysis showed that scutellarein induces apoptosis in both AGS and SNU-484 human gastric cancer cells and G2/M phase cell cycle arrest in SNU-484 cells. This study demonstrated that the Scutellarein on AGS and SNU-484 cells significantly inhibits cell proliferation and induces apoptotic cell death via down regulating MDM2 and activated the tumor suppresser protein p53, subsequently down regulating the IAP family proteins (cIAP1, cIAP2, and XIAP) leading to caspase-dependent apoptosis in AGS and SNU-484 cells.

Abstract
Korean Scutellaria baicalensis Georgi has been widely used in Korean folk medicines for its range of medicinal benefits, including its anticancer effect. The aim of the present study was to investigate the underlying molecular mechanism of action of a flavonoid extract from Korean Scutellaria baicalensis Georgi (FSB) on AGS human gastric cancer cells (gastric adenocarcinoma) in which FSB exhibits an anticancer effect. Treatment of AGS cells with FSB significantly inhibited cell viability in a concentration-dependent manner. Furthermore, FSB significantly increased the proportion of cells in sub-G1 phase, and Annexin V and Hoechst 33258 fluorescent staining confirmed the apoptotic cell death. Furthermore, western blotting results identified that treatment of AGS cells with FSB significantly downregulated the expression of caspase family members, namely procaspases 3 and 9, and poly(ADP-ribose) polymerase (PARP), and subsequently upregulated cleaved caspase 3 and cleaved PARP. It was observed that FSB treatment significantly decreased the mitochondrial membrane potential of AGS cells. In addition, the ratio of the mitochondrion-associated proteins B cell lymphoma 2-associated X protein and B cell lymphoma extra large was upregulated. The results of the present study provide novel insight into the underlying molecular mechanism of the anticancer effects of FSB on AGS human gastric cancer cells and indicate that FSB may be an alternative chemotherapeutic agent for the treatment of gastric cancer.

Abstract
Scutellaria baicalensis (SB; Chinese name, huangqin) is widely used in Chinese medicine as a traditional adjuvant in the chemotherapy of lung and liver cancer. Baicalein is one of the bioactive flavonoid components isolated from the root of SB. The present study aimed to observe the effect of baicalein, in combination with platin-based systemic chemotherapy (cisplatin), on cytotoxicity and apoptosis of human A549 lung cancer cells. The cell cultures were treated with baicalein, cisplatin, or a combination of the two. Cell viability and cytotoxicity was assayed by XTT, and cell apoptosis was measured by flow cytometry. The apoptosis-associated proteins were detected by western blot analysis. The cytokines in the culture supernatant were detected by ELISA. The present study revealed that cisplatin and the baicalein-cisplatin combination inhibited viability and promoted cytotoxicity of A549 cells. Cisplatin, baicalein and baicalein-cisplatin combination treatments were effective in the promotion of apoptosis of A549 cells. Baicalein and baicalein-cisplatin combination treatments also inhibited B cell lymphoma-2 (Bcl-2) and increased Bcl-2-associated X protein (Bax) expression. Additionally, cisplatin, baicalein and the baicalein-cisplatin combination promoted caspase-3 expression. Furthermore, the baicalein-cisplatin combination suppressed the secretion of interleukin-6, and baicalein and the combination of baicalein cisplatin decreased the secretion of tumor necrosis factor-α of A549 cells. The present study concluded that baicalein combined with cisplatin induced cytotoxicity and apoptosis of A549 cells, and such activity may be associated with the regulation of Bcl-2, Bax and caspase-3, indicating a promising alternative method for lung cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix Scutellariae (Scutellaria baicalensis Georgi, RS), a traditional herbal medicine commonly used to treat inflammation, hypertension, cardiovascular disease, bacterial and viral infections, is reported to treat lung cancer by supplements of modern medicine. The total flavonoid aglycones extract (TFAE) from RS is the most important composition for the pharmacodynamic effects. The present study was designed to evaluate the anti-lung tumor effect of TFAE on A549 cells and A549 cell nude mice xenografts. The aim of the study is to investigate the effect and mechanism of TFAE treating non-small cell lung cancer both in vitro and in vivo. MATERIALS AND METHODS The anti-tumor activity of TFAE in vitro was investigated using the MTT assay. The changes of cell invasion and migration were detected by Transwell assay and tube formation experiments were used to detect the anti-angiogenic effect. The anti-tumor effects of TFAE in vivo were evaluated in A549 cell nude mice xenografts. The mechanism of TFAE was detected by flow cytometry technology, western blot assay and immuno-histochemistry assay. RESULTS In vitro, TFAE inhibited the proliferation, invasion and migration of A549 cells in a dose- and time-dependent manner. In vivo, TFAE by oral administration at 100mg/kg for 30 days decreased the tumor volume and tumor weight in A549 cell xenograft by 25.5% with no statistical significance (P<0.05) compared to the cis-platinum positive control group (30.0%). The cell cycle and DNA synthesis experiment illustrated that TFAE could induce A549 cell cycle to arreste in S phase and DNA synthesis in A549 cells be inhibited, while TFAE had no influence on apoptosis of A549 cells. Western Blot assay demonstrated that the treatment of TFAE could make Cyclin D1 decrease and p53 increase both in vitro and in vivo. CONCLUSION TFAE displayed the inhibition effects of non-small cell lung cancer both in vitro and in vivo and the underlying mechanism might be related to the increased p53 protein expression and decreased Cyclin D1 expression, leading to cell cycle arrested in S phase and the decrease of DNA synthesis.

Abstract
The bark of Pinus massoniana is a traditional Chinese medicine for the treatment of various health disorders. Previous studies have demonstrated that P. massoniana bark extract (PMBE) may induce the apoptosis of hepatoma and cervical cancer cells. However, whether PMBE is able to inhibit the migration of lung cancer cells requires further investigation. In the current study, the effects of PMBE on the viability of human lung cancer A549 cells were detected using an MTT assay. The migration of lung cancer cells following exposure to PMBE were quantified using wound healing and Transwell assays, respectively. The expression levels of matrix metalloproteinase (MMP)-9 were determined using western blotting. The results revealed that PMBE significantly inhibited the growth of the lung cancer cells. In addition, the wound closure rate and the migration of the lung cancer cells were suppressed by PMBE. Furthermore, the expression levels of MMP-9 were reduced. These findings indicated that PMBE is able to restrict the migration and invasion of lung cancer cells, and that PMBE may serve as a novel therapeutic agent for patients with metastatic lung cancer in the future.

Abstract
Alternatively activated macrophages are more frequently involved in tumor growth, angiogenesis, and immunosuppression. A previous study showed that paeoniflorin, the major active constituent of Paeonia lactiflora Pallas, can inhibit tumor growth and lung metastases of Lewis lung tumor-bearing mice. This study tried to investigate whether paeoniflorin inhibited lung cancer metastasis by inhibiting the alternative activation of macrophages (M2 macrophage). Using a viability assay, the cytotoxicity of paeoniflorin on Lewis lung cancer cells and peritoneal macrophages were investigated. In vitro scratch wound and in vivo lung metastasis experiments were used to test the ability to inhibit the migration of paeoniflorin and the function of M2 macrophages. Flow cytometry was performed to test the cell cycle of Lewis lung cancer cells, and to test the M2 macrophages in peritoneal macrophages and subcutaneous transplantable tumor. It was found that paeoniflorin showed no inhibitory effect on the growth of Lewis lung cancer cells and peritoneal macrophages of mouse in vitro. Paeoniflorin could attenuate the migration of LLC stimulated by alternatively activated macrophages (stimulated for 24 h and 48 h, paeoniflorin 1, 3, 10, 30, 100 μmol·L(-1), P < 0.01 or P < 0.05 vs control group). Paeoniflorin could decrease the cell populations at S phases (paeoniflorin 10, 30, 100 μmol·L(-1), P < 0.05 vs control group) and increase the cell populations at G0-G1 phases of Lewis lung cancer cells (paeoniflorin 100 μmol·L(-1), P < 0.05 vs control group) and reduce the numbers of M2 macrophages in peritoneal macrophages induced by IL-4 (paeoniflorin 1, 3, 10, 30, 100 μmol·L(-1), P < 0.01 vs Control group). Paeoniflorin could reduce lung metastasis of Lewis lung cancer cells xenograft and decrease the numbers of M2 macrophages in subcutaneous xenograft tumour in vivo (paeoniflorin 20, 40 mg·kg(-1), P < 0.01 vs control group). These results suggest that paeoniflorin could reduce lung metastasis of Lewis lung cancer cells xenograft partly through inhibiting the alternative activation of macrophages.

Nagappan A, Lee HJ, Saralamma VVG, Park HS, Hong GE, Yumnam S, Raha S, Charles SN, Shin SC, Kim EH, Lee WS, Kim GS. Flavonoids isolated from Citrus platymamma induced G2/M cell cycle arrest and apoptosis in A549 human lung cancer cells. Oncol Lett 2016; 12:1394-1402. [PMID: 27446443 PMCID: PMC4950876 DOI: 10.3892/ol.2016.4793] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2015] [Accepted: 04/29/2016] [Indexed: 12/28/2022] Open
Abstract
Citrus platymamma hort. ex Tanaka belongs to the Rutaceae family and is widely used in folk medicines in Korea due to its anti-proliferative, anti-cancer, anti-oxidant, anti-inflammatory and anti-diabetic activities. However, the molecular mechanism of its anti-cancer effect is not well understood. The present study was conducted to elucidate the anti-cancer effect and molecular mechanism of flavonoids from Citrus platymamma (FCP) on A549 cells. FCP displayed concentration-dependent inhibition on A549 cells proliferation. Further, flow cytometry revealed that FCP significantly increased the sub-G1 (apoptotic cell population) and G2/M phase population, and the total number of apoptotic cells, in a dose-dependent manner. Nuclear condensation and fragmentation were also observed upon staining with Hoechst 33342 in FCP-treated A549 cells. Immunoblotting demonstrated a dose-dependent downregulation of cyclin B1, cyclin-dependent kinase 1, cell division cycle 25c, pro-caspases −3, −6, −8 and −9, and poly (adenosine diphosphate-ribose) polymerase (PARP) in FCP-treated A549 cells. In addition, FCP induced caspase-3 activation and subsequent PARP cleavage, and increased the B-cell lymphoma (Bcl)-2-associated X protein/Bcl-extra large ratio in A549 cells. These findings suggest that FCP induced G2/M arrest and apoptosis of A549 cells. The present study provides evidence that FCP may be useful in the treatment of human lung cancer.

Abstract
Rubus fairholmianus Gard. inhibits human melanoma (A375) and lung cancer (A549) cell growth by the caspase dependent apoptotic pathway. Herbal products have a long history of clinical use and acceptance. They are freely available natural compounds that can be safely used to prevent various ailments. The plants and plant derived products became the basis of traditional medicine system throughout the world for thousands of years. The effects of R. fairholmianus root acetone extract (RFRA) on the proliferation of A375 and A549 cells was examined in this study. RFRA led to a decrease in cell viability, proliferation and an increase in cytotoxicity in a dose dependent manner when compared with control and normal skin fibroblast cells (WS1). The morphology of treated cells supported apoptotic cell death. Annexin V/propidium iodide staining indicated that RFRA induced apoptosis in A375 and A549 cells and the percentages of early and late apoptotic populations significantly increased. Moreover, the apoptotic inducing ability of RFRA when analysing effector caspase 3/7 activity, indicated a marked increase in treated cells. In summary, we have shown the anticancer effects of RFRA in A375 and A549 cancer cells via induction of caspase dependent apoptosis in vitro. The extract is more effective against melanoma; which may suggest the usefulness of RFRA-based anticancer therapies.

Abstract
The response surface methodology (RSM) was used to optimize the conditions for total flavonoid extraction from Scutellaria baicalensis Georgi. The influences of the ethanol concentration, extraction time, temperature, and the liquid-solid ratio on flavonoid yield were investigated. Based on ANOVA results, a second-order quadratic polynomial model could be applied to characterize the extraction process. The following optimal extraction conditions were identified: ethanol concentration, 52.98 %; extraction time, 2.12 h; extraction temperature, 62.46 °C; and liquid-solid ratio, 35.23. The predicted extraction yield was 19.437 mg/g when these optimal conditions were used. The proposed method was successfully employed to extract flavonoids from S. baicalensis.

Abstract
Previous studies by our group showed that Qianliening capsules (QC), a clinically proven effective traditional Chinese formulation that has long been used in the treatment of benign prostatic hyperplasia (BPH), is capable of inhibiting BPH in vivo and in vitro via the promotion of apoptosis, suppression of the EGFR/STAT3 signaling pathway and regulating the expression of sex hormones as well as their receptors. However, the mechanism of its anti-BPH activity has remained to be fully elucidated. The present study aimed to investigate the mechanism underlying the anti-proliferative effect of QC in vivo and in vitro. Castrated male Sprage-Dawley (SD) rats where subcutaneously injected with testosterone propionate and the WPMY-1 cell line was stimulated with basic fibroblast growth factor in order to generate BPH in vivo and in vitro separately, both of which were then subjected to QC treatment. Finasteride was used as a positive control drug for the in vivo study. In the present study, it was found that treatment with QC or finasteride significantly reduced the prostatic index (PI=prostate wet weight/body weight x 100) in a rat model of BPH (P<0.05). In addition, reverse transcription quantitative polymerase chain reaction (RT-PCR) and western blot analyses showed that QC or finasteride treatment significantly inhibited model construction-induced upregulation of expression of proliferating cell nuclear antigen, cyclin D1 and cyclin-dependent kinase 4 in prostatic tissues of rats with BPH (P<0.05). The in vitro study further proved that QC exhibited anti-proliferative properties via G1/S cell cycle arrest in the WPMY-1 cell line, as evidenced by colony formation, flow cytometric cell cycle, immunoblot and RT-PCR analyses. In conclusion, the present study demonstrated that inhibition of cell proliferation via G1/S cell cycle arrest may be one of the underlying mechanisms of the effect of QC on BPH.

Abstract
Traditional herbal formulas made from Scutellariae Radix (SR), the root of Scutellaria baicalensis, have previously been used in the treatment of inflammatory diseases, such as atherosclerosis. The aim of the present study was to investigate the effects of SR on low-density lipoprotein (LDL) oxidation and inflammation in macrophages, which are early events in the development of atherosclerosis. High-performance liquid chromatography photo-diode array analysis was used to obtain a three-dimensional chromatogram of SR. The antioxidative effects of SR were evaluated by determining its scavenging activities against ABTS and DPPH radicals. The inhibitory effect of SR on LDL oxidation was examined using a thiobarbituric acid-reactive substance assay and a relative electrophoretic mobility assay. In addition, the anti-inflammatory effects of SR were evaluated in lipopolysaccharide (LPS)-induced RAW264.7 murine macrophage cells. The results showed that SR exhibited radical-scavenging activities in a dose-dependent manner; in addition, SR attenuated the Cu2+-induced oxidation of LDL as well as significantly inhibited nitric oxide (NO) production and inducible NO synthase (iNOS) expression in LPS-induced RAW264.7 cells. Furthermore, SR induced the protein expression of heme oxygenase-1 (HO-1) in RAW264.7 cells. In conclusion, the results of the present study demonstrated that SR decreased the oxidation of LDL and suppressed inflammatory responses in macrophages, which occurred at least in part via the induction of HO‑1. These results therefore suggested that SR may be a potential therapeutic agent for the treatment of atherosclerosis.

Abstract
Oldenlandia diffusa (OD) is commonly used with various diseases such as cancer, arthritis, and autoimmune disease. Liver cirrhosis is a predominant risk factor for hepatocellular carcinoma (HCC). Here, we show that the therapeutic effect of OD, which was investigated both in vitro and chemically, induced HCC model. OD significantly enhanced apoptosis and antiproliferative activity and reduced migration ability of HCC cells. In vivo, OD was treated twice a day for 28 days after confirmed HCC model through 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) imaging. The survival in OD treated groups was shown to have a greater therapeutic effect than the control group. 28 days after OD treatment, OD treated groups resulted in a significant reduction in tumor number, size, 18F-FDG uptake, and serum levels such as alanine transaminase, aspartate transaminase, and alkaline phosphate compared to the control group. Also, proliferated cells in tumor sites by OD were reduced compared to the control group. Furthermore, several rats in OD treated group survived over 60 days and liver morphology of these rats showed the difference between tumor mass and normal tissue. These results suggest that OD may have antiproliferative activity, inhibition of metastasis, and apoptotic effects in chemically induced HCC model and can have the potential use for clinical application as anticancer drug of the herbal extract.

Abstract
Metadherin (MTDH), a novel oncoprotein, has been implicated in the carcinogenesis in various aspects of tumor malignancy. Overexpression of the MTDH promotes the survival and proliferation of lung cancer cells. Agent that can suppress MTDH activation would have potential to be developed for cancer therapeutics. In this study, we investigated the antitumor effect of evodiamine in human non-small-cell lung carcinoma (NSCLC) A549 cell line and the inhibitory effect of evodiamine on MTDH pathway. 3-(4,5-Dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and annexin V/propidium iodide (PI) staining assays demonstrated that evodiamine or MTDH short hairpin RNA (shRNA) significantly inhibited proliferation of A549 cells via induction of apoptosis. Besides, evodiamine or MTDH shRNA-induced activation of the caspase-3 in A549 cells under same conditions. In addition, Western blotting analysis showed that treatment of A549 cells with evodiamine or MTDH shRNA resulted in an increase of proapoptotic protein Bax expression but decreased the expression levels of antiapoptotic protein Bcl-2 and MTDH, which altogether account for apoptotic cell death. Taken together, our results suggest that the evodiamine suppress the proliferation of lung cancer cells, at least, in part, via inhibition of MTDH expression and activation of apoptosis.

Abstract
Background Scutellaria baicalensis Georgi is a commonly used medicinal herb in several Asian countries like Korea, China and Japan for thousands of years. It has been reported to have various medicinal properties such as anti-microbial, anti-inflammatory and anti-cancer effects. However, the anti-inflammatory mechanism of S. baicalensis G at proteome level has not yet been reported. Hence, we performed a proteome analysis to study differentially expressed proteins and its anti-inflammatory role in lipopolysaccharide (LPS) stimulated L6 skeletal muscle cells response to flavonoids isolated from S. baicalensis G. Methods For that, 150 μg of proteins from the L6 cells of the control (Vehicle only), LPS treated and flavonoid treated groups were separated using 18 cm, pH 4–7 IPG strips in the first dimension and resolved by 12% linear gradient SDS-polyacrylamide gel electrophoresis (SDS-PAGE). The silver stained gels were analyzed by using progenesis SameSpots software and twenty six differentially expressed protein spots (≥2 fold, p < 0.05) were selected for matrix assisted laser desorption ionization- time of flight mass spectroscopy/mass spectrometry (MALDI-TOF/MS) analysis. Also, the expression of COX-2, iNOS and Annexin A2 proteins were analyzed by western blot. Results Totally, 12 differentially expressed proteins were successfully identified by MALDI-TOF/MS and database searching, that’s involved in inflammatory responses such vimentin, T-box transcription factor TBX3, annexin A1, annexin A2 and annexin A5. In addition, flavonoids inhibited the expression of COX-2, iNOS and Annexin A2 proteins in LPS-stimulated L6 skeletal muscle cells. Conclusions The findings revealed that the flavonoids from S. baicalensis G. directly protect the LPS stimulated inflammation process in L6 cells and, would be helpful to study further the muscle cell inflammatory mechanism. This is the first proteome study provide the anti-inflammatory mechanism of flavonoids from S. baicalensis G. in LPS stimulated L6 skeletal muscle cells.

Abstract
AIM OF STUDY Gegen Qinlian decoction (GQLD) is an ancient Chinese medicine formula for treating diseases with inner heat. The aim of this study is to investigate the antitumor effect of GQLD in human renal carcinoma cell (RCC) and its possible mechanism. METHOD High-performance liquid chromatography was used to identify and quantify active compounds in GQLD. Inhibition of tumor growth was determined by xenograft model. Cell viability on treatment with the decoction was determined by MTT assay; quantitative real-time polymerase chain reaction and immunoblotting were used to determine gene and protein expression; matrix metalloproteinase-2 (MMP-2) activity was detected by gelatin zymography and in vitro enzymatic reaction assay. RESULTS Thirteen major peaks were detected in the decoction, 8 of which were identified as berberine, baicalin and baicalein, pueranin, daizidin, liquiritin, wogonoside, and wogonin. GQLD exhibited potent inhibition on xenografted expansion of RCC cells. Interestingly, GQLD treatment did not induce cell death to RCC cells, but blocked the neoangiogenesis in xenografted RCC tumor. Particularly, we found that GQLD significantly inhibited MMP-2 in RCC cells, which was involved as a critical factor in avascular growth of RCC. GQLD directly suppressed the enzyme activity of MMP-2. Radix Scutellariae was the major herbal component that contributed to the potent inhibition of MMP-2. CONCLUSION The findings of this study provide experimental evidence of the inhibition of expansion and neoangiogenesis of renal carcinoma by Chinese medicine formula GQLD with involvement of MMP-2 suppression.

Abstract
Hesperidin, a natural flavonoid abundantly present in Citrus is known for its anti-cancer, anti-oxidant and anti-inflammatory properties. In this study we examined the effect of hesperidin on HepG2 cells. HepG2 cells treated with various concentration of hesperidin undergo a distinct type of programed cell death. Cytoplasmic vacuolization, mitochondria and endoplasmic reticulum swelling and uncondensed chromatin were observed in hesperidin treated cells. DNA electrophoresis show lack of DNA fragmentation and western blot analysis demonstrates lack of caspase activation and PARP cleavage. It was observed that hesperidin induced cell death is nonautophagic and also activate mitogen activated protein kinase ERK1/2. Taken together, the data indicate that hesperidin induces paraptosis like cell death in HepG2 cells with the activation of ERK1/2. Thus our finding suggests that hesperidin inducing paraptosis may offer an alternative tool in human liver carcinoma therapy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jiawei-Yupingfeng-Tang (JYT) is a Chinese herbal formula that is widely used to treat respiratory tract illness. However, the effect of JYT on respiratory viruses remains unknown. The influenza virus (IFV) and the human respiratory syncytial virus (HRSV) cause millions of cases of severe illness per year, and many of these illnesses develop into lethal pneumonia. The aim of this study is to evaluate whether JYT can be used to treat these infections. MATERIALS AND METHODS The effect of JYT against IFV and HRSV was tested using a plaque reduction assay in the lower respiratory tract cell line A549. The expression of ICAM-1 was determined by real-time RT-PCR and western blotting. A mouse model infected with lethal influenza developing into interstitial pneumonia was used to evaluate the effect of JYT in vivo. RESULTS JYT extract inhibited both IFV and HRSV in a dose-dependent manner when given before, during and after a viral infection. JYT was effective in blocking the entry of the virus. Furthermore, pre-treatment with JYT reduced the susceptibility of cells to the invasion of HRSV by inhibiting the expression of ICAM-1. Importantly, JYT extract increased the survival rate of lethal influenza-infected mice, prolonged the survival time and alleviated the virus-induced lung lesions, which is comparable with the effects of ribavirin treatment. CONCLUSIONS These data support JYT as an alternative modality to be used in the treatment of respiratory viral infection induced by HRSV and IFV.

Chem Cent J 2012; 6:97.

Abstract
BACKGROUND Arnica montana L. and Artemisia absinthium L. (Asteraceae) are medicinal plants native to temperate regions of Europe, including Romania, traditionally used for treatment of skin wounds, bruises and contusions. In the present study, A. montana and A. absinthium ethanolic extracts were evaluated for their chemical composition, antioxidant activity and protective effect against H2O2-induced oxidative stress in a mouse fibroblast-like NCTC cell line. RESULTS A. absinthium extract showed a higher antioxidant capacity than A. montana extract as Trolox equivalent antioxidant capacity, Oxygen radical absorbance capacity and 2,2-diphenyl-1-picrylhydrazyl free radical-scavenging activity, in correlation with its flavonoids and phenolic acids content. Both plant extracts had significant effects on the growth of NCTC cells in the range of 10-100 mg/L A. montana and 10-500 mg/L A. absinthium. They also protected fibroblast cells against hydrogen peroxide-induced oxidative damage, at the same doses. The best protection was observed in cell pre-treatment with 10 mg/L A. montana and 10-300 mg/L A. absinthium, respectively, as determined by Neutral red and lactate dehydrogenase assays. In addition, cell pre-treatment with plant extracts, at these concentrations, prevented morphological changes induced by hydrogen peroxide. Flow-cytometry analysis showed that pre-treatment with A. montana and A. absinthium extracts restored the proportion of cells in each phase of the cell cycle. CONCLUSIONS A. montana and A. absinthium extracts, rich in flavonoids and phenolic acids, showed a good antioxidant activity and cytoprotective effect against oxidative damage in fibroblast-like cells. These results provide scientific support for the traditional use of A. montana and A. absinthium in treatment of skin disorders.
