Abstract
OBJECTIVE To observe the proliferation inhibition, cell cycle, and apoptosis of human glioma cell line SHG-44 treated with different concentration of Schidandrin B and explore the effect of Schidandrin B on glioma SHG-44 cells. METHODS Glioma SHG-44 cells were treated with Schidandrin B (0, 50, 100 or 200 μg/mL) for 24, 48, 72 and 96 h, and cells were treated with vehicle as control. Viability of cells were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) analysis; cell cycle was examined with flow cytometry assay; apoptosis was detected with annexin V assay. Bax and caspase-3 proteins expression were checked by Western blot. RESULTS MTT analysis showed that viability of glioma SHG-44 cells significantly decreased after exposure to Schidandrin B for the indicated time. Flow cytometry revealed that the number of cells in the sub G1 phase was increased, however, the number of cells in G0/G1, S and G2/M phases were decreased after treatment with 50, 100 or 200 μg/mL Schidandrin B, compared with the respective control group. Annexin V analysis confirmed that apoptosis rates of the control group, 50, 100, and 200 μg/mL Schidandrin B group were 1.76%±0.47%, 13.98%±5.05%, 19.64%±5.53% and 63.28%±6.88% respectively, apoptotic rate increased significantly with dose-dependent manner, and apoptosis of cells were observed under the inverted microscope after 100 μg/mL Schidandrin B treatment. Bax and caspase-3 protein were highly expressed in Schidandrin B group compared with the control group. CONCLUSION The apoptosis could be induced by different concentration of Schidandrin B on glioma SHG-44 cells, and the mechanism may be directly excited by Schidandrin B in glioma SHG-44 cells through activating mitochondrial pathway.

Synergistic Effect and Molecular Mechanisms of Traditional Chinese Medicine on Regulating Tumor Microenvironment and Cancer Cells. BIOMED RESEARCH INTERNATIONAL 2016; 2016:1490738. [PMID: 27042656 PMCID: PMC4793102 DOI: 10.1155/2016/1490738] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/25/2015] [Accepted: 01/26/2016] [Indexed: 12/23/2022]
Abstract
The interaction of tumor cells with the microenvironment is like a relationship between the “seeds” and “soil,” which is a hotspot in recent cancer research. Targeting at tumor microenvironment as well as tumor cells has become a new strategy for cancer treatment. Conventional cancer treatments mostly focused on single targets or single mechanism (the seeds or part of the soil); few researches intervened in the whole tumor microenvironment and achieved ideal therapeutic effect as expected. Traditional Chinese medicine displays a broad range of biological effects, and increasing evidence has shown that it may relate with synergistic effect on regulating tumor microenvironment and cancer cells. Based on literature review and our previous studies, we summarize the synergistic effect and the molecular mechanisms of traditional Chinese medicine on regulating tumor microenvironment and cancer cells.

Abstract
Sauromatum giganteum (Engl.) Cusimano & Hett Tuber are used in Chinese folklore medicine for treatment of neoplasms. However, the claim has not been scientifically validated. The aim of the study is to screen the antitumor bioactive fraction of Sauromatum giganteum (Engl.) Cusimano & Hett Tuber and sensitive tumor cell lines using a cytotoxicity assay in vitro and tumor transplantation method in vivo, to support its use in folk medicine. The petroleum ether fraction, chloroform fraction, ethyl acetate fraction, n-butanol fraction and water fraction were successively extracted by turn by the maceration under reflux assay. Screening of antitumor bioactive fraction and sensitive cell lines were measured by MTT assay and the serum pharmacology method, and in vivo the antitumor activities of the active fraction was evaluated by using S180 or H22 tumor-bearing mice model and Kunming mice. The active constituents of ethyl acetate fraction of Sauromatum giganteum (Engl.) Cusimano & Hett were characterized by UPLC-TOF-MS. Compared with control groups, mice serum containing ethyl acetate fraction had a inhibition effect on SMMC-7721 cell, SGC-7901 cell, MCF-7 cell, HeLa cell, A549 cell, HT-29, and MDA-MB-231, respectively, but mice serum containing other four fractions had no different with that of control group. The inhibition capabilities of mice serum containing ethyl acetate fraction on the seven cell lines in descending order is SGC-7901 > SMMC-7721 > MCF-7 > HT-29 > A549 > HeLa > MDA-MB-231. In vivo the inhibition rate of 106, 318, 954 mg/kg·d ethyl acetate fraction dry extract to sarcoma S180 is 15.22%, 26.15% and 40.24%, respectively, and life prolonging rate to hepatoma H22 is 33.61%, 40.16% and 55.74%. A total of 14 compounds were identified in the ethyl acetate fraction of Sauromatum giganteum (Engl.) Cusimano & Hett. The results of the experimental studies proved the antitumor activity of Sauromatum giganteum (Engl.) Cusimano & Hett and supported the traditional use of this plant. These data indicate the potential for the use of ethyl acetate fraction of Sauromatum giganteum (Engl.) Cusimano & Hett Tuber in tumor therapy, anti-tumor activity on cancer cell line in descending order is SGC-7901 > SMMC-7721 > MCF-7 > HT-29 > A549 > HeLa > MDA-MB-231.

Abstract
BACKGROUND Both alcohol and aqueous extracts of Sauromatum giganteum(Engl.) Cusimano and Hett, the dried root tuber of which is named Baifuzi in Chinese, have been used for folklore treatment of cancer in Northeast of China. However, little is known about which is most suitable to the cancer therapy. MATERIALS AND METHODS Serum pharmacology and MTT assays were adopted to detect the effects of ethanol and aqueous extracts of Sauromatum giganteum(Engl.) Cusimano and Hett , prepared by heat reflux methods, on proliferation of different cancer cells. RESULTS Cancer cells treated with medium supplemented with 10%, 20%, 40% serum(v/v) containing ethanol extract had a decline in viability, with inhibition rates of 7.69%, 21.8%, 41.9% in MCF-7 cells, 42.8%, 48.1%, 51.8% in SGC-7901 cells, 44.1%, 49.2%, 53.7% in SMMC-7721 cells, 6.8%, 15.2%, 39.8% in HepG2 cells, 7.57%, 16.3%, 36.2% in HeLa cells, 6.24%, 12.5%, 27.4% in A549 cells, and 7.20%, 17.5%, 31.3% in MDA-MB-231 cells, respectively. Viability in the aqueous extract groups was no different with that of controls. CONCLUSIONS An ethanol extract of Sauromatum giganteum(Engl.) Cusimano and Hett inhibited the proliferation of SMMC-7721, SGC-7901 and MCF-7 cells, which supports the use of alcoholic but not aqueous extracts for control of sensive cancers, which might include hepatocarcinoma, gastric cancer and breast cancer.

Wu G, Fan H, Huang Y, Zheng C, Ye J, Liu X. Duhuo Jisheng Decoction‑containing serum promotes proliferation of interleukin‑1β‑induced chondrocytes through the p16‑cyclin D1/CDK4‑Rb pathway. Mol Med Rep 2014; 10:2525-34. [PMID: 25189115 DOI: 10.3892/mmr.2014.2527] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2013] [Accepted: 08/06/2014] [Indexed: 11/06/2022] Open
Abstract
Duhuo Jisheng Decoction (DHJSD) is a traditional Chinese herbal medicine that has multiple uses, including as a treatment for osteoarthritis (OA). However, the molecular mechanisms underlying the therapeutic effects of DHJSD on OA remain unknown. In the present study, a serum pharmacological method was applied to investigate the effects of DHJSD on the proliferation of chondrocytes treated with interleukin‑1β (IL‑1β) in vitro. This is a cell model commonly used to reproduce the mechanisms involved in degenerative arthropathies, including OA. The most effective intervention conditions of DHJSD serum were examined by MTT assay. The degenerative chondrocyte model was established by IL‑1β‑culture for 24 h, and was verified by optical microscopy and immunohistochemical analyses. Following the successful establishment of the degenerative chondrocyte model, the chondrocytes were subsequently randomly divided into two groups: The blank serum group and the DHJSD treatment group. Subsequent to treatment with the corresponding serum, cell proliferation was detected by MTT assay and DNA staining followed by FACS analysis, and the mRNA and protein expression levels of cyclin D1, cyclin‑dependent kinase 4 (CDK4), retinoblastoma tumor suppressor protein (Rb) and p16 were measured by reverse transcription polymerase chain reaction and western blotting, respectively. The results indicated that the most effective condition for the promotion of chondrocyte proliferation was 10% concentration of DHJSD 2‑h serum, and the degenerative chondrocyte model was successfully reproduced by IL‑1β‑treatment for 24 h. The mRNA and protein expression levels of cyclin D1, CDK4 and Rb in the DHJSD serum‑treated cells were significantly increased compared with those in the blank serum group, whereas p16 expression was significantly downregulated. These results indicate that treatment of cells with DHJSD‑containing serum is able to promote IL‑1β‑induced chondrocyte proliferation by promoting G1/S phase transition via modulating the expressions of cyclin D1, CDK4, Rb and p16, which contribute to the clinical efficacy of DHJSD in OA.
