Treated and untreated melanoma cells were cultured in the glucose-free medium for 30 min, and followed addition of 2-NBDG (100 μM) for 20 min and analyzed with a FACSCalibur flow cytometer (BD Bioscience). Copyright © 2020 Huang, Peng, Nayak, Wang, Si, Liu, Dou, Xu and Peng. However, our current studies clearly showed that treatment with baicalin also dramatically induced tumor cell apoptosis in both human and mouse melanoma cells, but its effect is less potent than that of baicalein (Figure 3 and Supplementary Figure S1). Pharmacol. JAMA Oncol. Baicalein and baicalin treatments promote melanoma cell apoptosis. A precise understanding of biological functions and mechanisms of these two natural compounds on different types of cancers will provide novel targets for the clinical therapy against cancers including melanoma. Baicalein and baicalin inhibit tumor growth and development in vivo in a colon…, NLM 2013;63:11–30. All these studies collectively indicate that baicalein and baicalin can induce tumor cell senescence and apoptosis, and suppress tumor proliferation and growth in vivo. Toxicol. We observed that baicalein and baicalin treatments markedly suppressed tumor cell proliferation as indicated by a decrease of Ki-67+ cell populations in tumor tissues (Figures 8D,E). Melanoma cells were transfected with pCDNA-Glut1 or control vector plasmids for 24 h, then cultured for 3 days in the presence of baicalein or baicalin (40 μM for Mel586, A375, and SK-mel-2 cells, and 50 μM for B16F0 cells). Furthermore, tumor sizes collected from the baicalein- or baicalin-treated B16F0 groups were much smaller than those in the PBS treatment group (Figure 8B). PLX4032, a selective BRAF(V600E) kinase inhibitor, activates the ERK pathway and enhances cell migration and proliferation of BRAF melanoma cells. SHOC2 and CRAF mediate ERK1/2 reactivation in mutant NRAS-mediated resistance to RAF inhibitor. p values were determined by the one-way analysis of variance (ANOVA). In mice, baicalin produces anxiety-lowering effects without causing drowsiness or muscle relaxation. Traditional Chinese medicines have been recently recognized as a new source of anticancer drugs and new chemotherapy adjuvant to enhance the efficacy of chemotherapy and to ameliorate the side effects of cancer chemotherapies however their healing mechanisms are still largely unknown. Mechanistic studies further demonstrated that baicalein and baicalin-mediated suppression of melanoma growth and development is through the inhibition of glucose metabolism in tumor cells, promoting tumor cell … Total RNA was isolated from the tumor cells and analyzed by Real-time PCR (C). Jakob, J. Although significant progress has been made to develop target therapy for melanoma, the mutations on N-RAS and B-RAF occurred in tumor cells have been a significant challenge for successful treatment of melanoma patients (Brose et al., 2002; Omholt et al., 2003; Thumar et al., 2014).

Two hundred to five hundred per well of melanoma cells treated with different concentrations of baicalein or baicalin, were seeded in 6-well plates and cultured for 10–14 days. Molecular Weight 446.36 . Baicalin The present study demonstrated that the Scutellariae radix compounds baicalein and baicalin may serve as drugs for the treatment of autoimmune diseases, including rheumatoid arthritis and inflammatory bowel disease. Among the major components of S. baicalensis , baicalein strongly inhibits SARS-CoV-2 3CLpro activity with an IC50 of 0.39 μM. These data clearly suggest that both baicalein and baicalin have potent anti-tumor effects against melanoma and are potential novel and universal target drugs for melanoma therapy. Baicalin and baicalein, two flavonoids found in the roots of Scutellaria baicalensis , in the leaves of Thymus vulgaris and Oroxylum indicum , were tested for their anti-inflammatory activity as well as for their cytotoxicity. All the results from both in vivo and in vitro studies indicate that baicalein and baicalin can rewrite tumor metabolism and have potent anti-tumor effects in melanoma. Great progress has made in diagnosis and treatment with melanoma, but the overall survival of advanced melanoma is still very low. BioPure Baikalin Powder is a powdered extract from the root of Scutellaria baicalensis, also known as Chinese Skullcap, Huang-Qin, or Baikal Skullcap. Baicalein (Purity 98.5%) and baicalin (Purity 91.5%) were purchased from the Kanghua Company (Nanjing, Jiangsu, China) and were dissolved in dimethyl sulfoxide (DMSO, Sigma, St. Louis, Mo, United States). These studies clearly indicate that baicalein and baicalin can control tumor growth and development metabolically and have great potential as novel and universal drugs for melanoma therapy. Baicalein may be used to treat liver cancer. *p < 0.05 and ***p < 0.001, compared with the medium control group. Baicalein and baicalin strongly inhibit melanoma cell behaviors and functions, including tumor cell growth and proliferation, as well as colony formation and migration. Melanoma cells were treated with or without indicated concentrations of baicalein and baicalin for 72 h and then phosphorylated mTOR, p70S6K, and 4E-BP1 in tumor cells were determined by the flow cytometry analyses. [Pubmed:25739393] BMB Rep. 2015 Sep;48(9):519-24. Scale bar: 50 μm. Biophys.

Melanoma cells were cultured for 36 or 72 h in the presence of different concentrations of baicalein and baicalin, and apoptosis was analyzed after staining with PE-labeled Annexin V and 7-AAD (BD Biosciences, San Diego, CA, United States) (Liu et al., 2015; Dou et al., 2018; Wang et al., 2018). Impact Factor 5.201 | CiteScore 5.8More on impact ›, School of Medicine, Southern Illinois University Carbondale, United States, The Research Institute at Nationwide Children's Hospital, United States. The suppressive effects are mechanistically due to the induction of colon cancer cell apoptosis and senescence mediated by baicalein and baicalin, respectively. We further revealed that their anti-tumor effects are mechanistically due to the suppression of cancer cell glucose metabolism and induction of melanoma cell apoptosis and senescence. We then further confirmed whether baicalein and baicalin-mediated inhibition of tumor growth in vivo is due to suppression of glucose metabolism in tumor cells. Cancer Cell 18, 683–695. For some experiments, tumor cells were transfected with Retro-Rheb, pCDNA-Glut1 or control plasmids, or pretreated with DMOG (0.1 mM, Sigma) for 24 h, then cultured for 3 days in the presence of different concentrations of baicalein or baicalin (Li et al., 2019). Although many inhibitors have been developed to target the mutations and/or activated signaling pathways, the overall effects of the inhibitors against melanoma are limited in certain types of clinical patients (Brose et al., 2002; Thumar et al., 2014). *p < 0.05, **p < 0.01, and ***p < 0.001, compared with the medium control group.

All stained cells were analyzed on a FACSCalibur flow cytometer (BD Bioscience) and data analyzed with the FlowJo software (Tree Star). The expression levels of each gene were normalized to β-actin expression levels and adjusted to the levels in untreated tumor cells (medium). These results collectively indicate baicalein and baicalin can strongly inhibit tumor cell growth and biological behaviors in melanoma. However, how and whether baicalein and baicalin inhibit colon cancer is unclear. Pharmacol. (A,B) Baicalein and baicalin treatments dramatically decreased the numbers and sizes of tumor colonies in SK-MEL-2 and A375 cells. Data shown in different melanoma cells are mean ± SD from three independent experiments.

Melanomas acquire resistance to B-RAF(V600E) inhibition by RTK or N-RAS upregulation. Expression levels of each gene were determined by reverse-transcription PCR using specific primers, and mRNA levels in each sample were normalized to the relative quantity of β-actin gene expression. After 4 days post tumor injection (tumor size reached around 5 × 5 mm), baicalein and baicalin (80 mg/kg) were administered through intraperitoneal injection into the tumor-bearing mice, respectively, at every other day for 2 weeks. Consistent with the results from Retro-Rheb transfection, activation of HIF1α signaling with DMOG in tumor cells markedly blocked the inhibition of gene expression of glucose transporters and glycolytic enzymes and prevented induction of senescence in melanoma cells mediated by baicalein and baicalin (Figures 7A,B). (1956). Unfortunately, most baicalein is rather quickly metabolized within the human body to baicalin (spelled the same but without the “e”), which has a sugar attached to it. doi: 10.1038/nm.2941. (2013). Baicalein and baicalin are active components of the Scutellaria baicalensis Georgi and both have broad anti-tumor activity. 5, 722–728. 1) Anxiety Baicalein and baicalin inhibit the action potential of the neurons that raise anxiety. We show here that low micromolar concentrations of baicalein, and especially its oxidized forms, inhibit the formation of alpha-synuclein fibrils. While plasma contained predominantly conjugates of baicalein, wogonin, and oroxylin A, both aglycones and conjugates were found in all other tissues investigated and in tumor. Traditional Chinese medicines have been recently recognized as a new source of anticancer drugs and new chemotherapy adjuvant to enhance the efficacy of chemotherapy and to ameliorate the side effects of cancer chemotherapies however their healing mechanisms are still largely unknown. DMCM (methyl-6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate) is a drug from the beta-carboline family. TLR8-mediated metabolic control of human treg function: a mechanistic target for cancer immunotherapy. Tumor growth was evaluated. Furthermore, consistent with the previous reports in other tumor cells, treatment with baicalein significantly induced tumor cell apoptosis in both human and mouse melanoma cells at 36 and 72 h (Figures 3A,B and Supplementary Figure S1) (Takahashi et al., 2011; Huang et al., 2012; Zhang et al., 2013; Dou et al., 2018; Wang et al., 2018).

Acta 1830, 3670–3695. 23.4) is one of the main constituents responsible for the pharmacologic actions of Scutellaria baicalensis, a Chinese herbal medicine used for centuries to treat psoriasis. Results shown in the histogram are summaries of mean ± SD from three independent experiments. It is extracted from the roots of the Scutellaria baicalensis and Scutellaria lateriflora. Acquired resistance to BRAF inhibitors mediated by a RAF kinase switch in melanoma can be overcome by cotargeting MEK and IGF-1R/PI3K. In vitro antiproliferative effects on CRC cells were verified using an in vivo xenograft nude mouse model. Baicalin and baicalein inhibit transforming growth factor-beta1-mediated epithelial-mesenchymal transition in human breast epithelial cells. (2010). (B) Activation of mTORC1-HIFα signaling prevented senescence induction in melanoma cells mediated by baicalein and baicalin. Baicalein and baicalin treatments markedly suppressed gene expression of Glut1, Glut3, HK2, TPI, GPI, and PFK1 in both human and mouse melanoma cells (Figure 5C). In addition, we demonstrated that baicalein and baicalin can suppress tumorigenesis and tumor growth in vivo in the melanoma model. Consistent with our above and previous results, baicalein had more potent suppressive effect on mTOR signaling in tumor cells than that of baicalin. Nat. Baicalin, along with its aglycone baicalein, is a positive allosteric modulator of the benzodiazepine site and/or a non-benzodiazepine site of the GABA A receptor. All animal studies have been approved by the Institutional Animal Care Committee. Recently, concerns about drug interaction with baicalin and/or baicalein have been raised, because of the co-administration of Scutellaria species with certain drugs. Furthermore, the metabolic inhibition by baicalein and baicalin involves the mTOR-HIF-1α signaling regulation. Tumor size was measured with calipers every 2 days. MATRIGEL® basement membrane matrix was obtained from Becton Dickinson (Bedford, MA). Science 123, 309–314. Inhibition of Autophagy Amplifies Baicalein-Induced Apoptosis in Human Colorectal Cancer. J.

JD provided the baicalein and baicalin compounds and discussion of the manuscript. Baicalein (5,6,7-trihydroxyflavone) is a flavone, a type of flavonoid, originally isolated from the roots of Scutellaria baicalensis and Scutellaria lateriflora. In addition, baicalin contains a glucuronide moiety in its structure, by which baicalin and baicalein show complex pharmacokinetic behaviors, due to the interconversion between them by phase II enzymes in the body. (C) Treatments with both baicalein and baicalin had much lower tumor weights compared with that of PBS control group. Cancer. Baicalin and its aglycon baicalein are flavonoids extracted from Scutellaria baicalensis, an important traditional Chinese herb. Potential Treatment of Breast and Lung Cancer Using. Human melanoma cell lines (A375 and SK-MEL-2) and mouse melanoma cell line B16F were originally purchased from the American Type Culture Collection (ATCC, Manassas, VA, United States). To test this possibility, we first analyzed the phosphorylation and activation of mTOR and its downstream substrates p70S6K and 4E-BP1 in melanoma cells treated with or without baicalein and baicalin. B16F0 cells (1 × 105/mouse) were subcutaneously injected into NSG mice. *p < 0.05, **p < 0.01, and ***p < 0.001, compared with the medium control group. We found that baicalein and baicalin strongly suppressed tumor growth and proliferation of both human and mouse melanoma cells (Mel586, SK-MEL-2, A375 and B16F0) regardless of the mutation statuses of B-RAF and N-RAS (Figures 1A,B). Our in silico interaction assays predicted that both compounds exhibited the strongest binding affinities towards ZIKV NS5, while the virus envelope glycoprotein was the least likely target protein. Cell colonies were fixed with 4% formaldehyde, stained with 0.5% crystal violet for 15 min at room temperature, washed for several times and then counted under a microscope, as we described previously (Liu et al., 2015; Dou et al., 2018; Wang et al., 2018). Phan T, Nguyen VH, A'lincourt Salazar M, Wong P, Diamond DJ, Yim JH, Melstrom LG. Interestingly, we observed that high concentrations of baicalein and baicalin (above 50 μM) were required to induce senescence in B16F0 mouse melanoma cells compared with those in human melanoma cell lines in in vitro treatment (Figures 4A,B). The slides were washed with PBS and added a secondary antibody-conjugated with AF594 and DAPI at diluted concentrations of 1:300 and 1:2500, under room temperature for 1 h. The stained slides were analyzed by an immunofluorescence microscopy. (F,G) Large amounts of senescent tumor cells were observed in the tumor tissues from both treatments of baicalein and baicalin in NSG mice.  |  Moreover, resistance against the target inhibitors and/or activation of alternative survival signaling pathways in cancer cells also keep merging in cancer patients (Nazarian et al., 2010; Villanueva et al., 2010; Gowrishankar et al., 2012). A standardized and purified extract of S. baicalensis containing baicalein, oroxylin A, and wogonin exerted anti … A substantial amount of baicalin (34–63%) was methylated to oroxylin A and its conjugates in various organs during absorption. To further investigate the causative role of glucose metabolism inhibition in cell senescence and suppression of melanoma cells mediated by these two compounds, we determined whether we can prevent tumor cell senescence mediated by baicalein and baicalin if we promote glucose mentalism through overexpression of Glut1 gene in the melanoma cells.

Frozen slides were recovered to room temperature, washed with PBS and treated with 3% H2O2 in PBS for 30 min. Keywords: B16F0 melanoma cells were subcutaneously injected into NSG mice. Development of novel therapeutic strategies and/or effective drugs is a significant challenge and urgently needed for clinical patients (Brose et al., 2002; Omholt et al., 2003; Thumar et al., 2014). (B,C) Baicalein and baicalin treatments down-regulated HIF1α protein and mRNA expression in melanoma cells. Baicalein and baicalin inhibit tumor growth and tumorigenesis of melanoma in vivo. We observed that the numbers and sizes of tumor cell colonies were significantly decreased in SK-MEL-2 and A375 tumor cells after treatment with baicalein or baicalin (Figures 2A,B). (2010). Glucose uptake of melanoma cells was determined by the flow cytometry with addition of 2-NBDG (100 μM) for 30 min after 3-day culture with the indicated concentrations of baicalein and baicalin. Here we demonstrate that baicalein and baicalin can significantly inhibit human colon cancer cell growth and proliferation. doi: 10.1038/nature08902, Pusapati, R. V., Daemen, A., Wilson, C., Sandoval, W., Gao, M., Haley, B., et al. (2015). We demonstrated that baicalein and baicalin can significantly inhibit both human and mouse melanoma cell growth and proliferation, suppress tumor cell colony formation and migration, as well as induce apoptosis and senescence in melanoma cells. We will continue our future studies to explore the possibility that combining baicalein or baicalin treatment with other therapeutic strategies including immunotherapy will synergistically enhance anti-tumor efficacy in different melanoma models. Metabolic reprogramming: a cancer hallmark even warburg did not anticipate. Here we demonstrate that baicalein and baicalin, the active components of the Chinese traditional medicinal plant Scutellaria baicalensis Georgi, can significantly inhibit melanoma cell growth and proliferation, suppress tumor cell colony formation and migration, as well as induce apoptosis and senescence in melanoma cells. We further determined whether baicalein and baicalin can inhibit tumor growth of melanoma cells. Melanoma cell lines were cultured at a started number of 2 × 105/well in 6-well plates in the presence of different concentrations of baicalein and baicalin in triplicate wells, as we previously described (Dou et al., 2018; Wang et al., 2018).
