Abstract
AbstractBackgroundClerodendrumis a genus of about 500 species belongs to the family Lamiaceae. Many species of this genus have been proved for the treatment of various diseases. This study was aimed to evaluate the cytotoxic effect of different solvents and their most active fractions ofClerodendrum thomsoniaeBalf.f. in different human cancer cell lines. Aerial parts of the plant were subjected to Soxhlet extraction. Phytochemical analysis was done by using standard tests. In vitro anti-cancer activity on MCF-7, Hep-G2, A549, HT-29, MOLT-4, Hela, and Vero cell lines were evaluated by MTT assay.ResultsPhytochemical analysis confirmed the presence of most of the phytoconstituents in ethyl acetate extracts and the same extracts were found to be more cytotoxic activity to cancer cell lines MCF-7,Hep-G2,A549,HT–29, MOLT-4, and Hela with IC50values 29.43 ± 1.44 μg/ml, 43.22 ± 1.02 μg/ml, 56.93 ± 1.41 μg/ml, 60.68 ± 1.05 μg/ml, 69.83 ± 1.33 μg/ml, and 40.02 ± 1.14 μg/ml respectively, while it had no cytotoxic effect on normal Vero cells IC50= 367.5 ± 1.03 μg/ml. Ethyl acetate extracts were selected for the fractionation and MCF-7 cell line was used repeat MTT assay and found that fraction F5 was the most active fraction with IC5017.33 ± 0.54 μg/ml.ConclusionThese findings have proved thatClerodendrum thomsoniaeBalf.f. have significant cytotoxicity especially for breast cancer cell lines.

Cordyceps militaris Exerts Anticancer Effect on Non-Small Cell Lung Cancer by Inhibiting Hedgehog Signaling via Suppression of TCTN3. Integr Cancer Ther 2021; 19:1534735420923756.

Abstract
This study aimed to investigate the effect of Cordyceps
militaris extract on the proliferation and apoptosis of non–small
cell lung cancer (NSCLC) cells and determine the underlying mechanisms. We
performed a CCK-8 assay to detect cell proliferation, detection of morphological
changes through transmission electron microscopy (TEM), annexin V–FITC/PI double
staining to analyze apoptosis, and immunoblotting to measure the protein
expression of apoptosis and hedgehog signaling–related proteins, with C
militaris treated NSCLC cells. In this study, we first found that
C militaris reduced the viability and induced morphological
disruption in NSCLC cells. The gene expression profiles indicated a
reprogramming pattern of genes and transcription factors associated with the
action of TCTN3 on NSCLC cells. We also confirmed that the C
militaris–induced inhibition of TCTN3 expression affected the
hedgehog signaling pathway. Immunoblotting indicated that C
militaris–mediated TCTN3 downregulation induced apoptosis in NSCLC
cells, involved in the serial activation of caspases. Moreover, we demonstrated
that the C militaris negatively modulated GLI1 transcriptional
activity by suppressing SMO/PTCH1 signaling, which affects the intrinsic
apoptotic pathway. When hedgehog binds to the PTCH1, SMO dissociates from PTCH1
inhibition at cilia. As a result, the active GLI1 translocates to the nucleus.
C militaris clearly suppressed GLI1 nuclear translocation,
leading to Bcl-2 and Bcl-xL down-regulation. These results suggested that
C militaris induced NSCLC cell apoptosis, possibly through
the downregulation of SMO/PTCH1 signaling and GLI1 activation via inhibition of
TCTN3. Taken together, our findings provide new insights into the treatment of
NSCLC using C militaris.

Cordyceps militaris induces apoptosis in ovarian cancer cells through TNF-α/TNFR1-mediated inhibition of NF-κB phosphorylation. BMC Complement Med Ther 2020; 20:1. [PMID: 32020859 PMCID: PMC7076896 DOI: 10.1186/s12906-019-2780-5] [Citation(s) in RCA: 73] [Impact Index Per Article: 18.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Accepted: 11/29/2019] [Indexed: 01/16/2023] Open
Abstract
BACKGROUND Cordyceps militaris (L.) Fr. (C. militaris) exhibits pharmacological activities, including antitumor properties, through the regulation of the nuclear factor kappa B (NF-κB) signaling. Tumor Necrosis Factor (TNF) and TNF-α modulates cell survival and apoptosis through NF- κB signaling. However, the mechanism underlying its mode of action on the NF-κB pathway is unclear. METHODS Here, we analyzed the effect of C. militaris extract (CME) on the proliferation of ovarian cancer cells by confirming viability, morphological changes, migration assay. Additionally, CME induced apoptosis was determined by apoptosis assay and apoptotic body formation under TEM. The mechanisms of CME were determined through microarray, immunoblotting and immunocytochemistry. RESULTS CME reduced the viability of cells in a dose-dependent manner and induced morphological changes. We confirmed the decrease in the migration activity of SKOV-3 cells after treatment with CME and the consequent induction of apoptosis. Immunoblotting results showed that the CME-mediated upregulation of tumor necrosis factor receptor 1 (TNFR1) expression induced apoptosis of SKOV-3 cells via the serial activation of caspases. Moreover, CME negatively modulated NF-κB activation via TNFR expression, suggestive of the activation of the extrinsic apoptotic pathway. The binding of TNF-α to TNFR results in the disassociation of IκB from NF-κB and the subsequent translocation of the active NF-κB to the nucleus. CME clearly suppressed NF-κB translocation induced by interleukin (IL-1β) from the cytosol into the nucleus. The decrease in the expression levels of B cell lymphoma (Bcl)-xL and Bcl-2 led to a marked increase in cell apoptosis. CONCLUSION These results suggest that C. militaris inhibited ovarian cancer cell proliferation, survival, and migration, possibly through the coordination between TNF-α/TNFR1 signaling and NF-κB activation. Taken together, our findings provide a new insight into a novel treatment strategy for ovarian cancer using C. militaris.

Abstract
This study aimed to investigate the effect of Cordyceps militaris extract on the proliferation and apoptosis of carboplatin- resistant SKOV-3 and determine the underlying mechanisms for overcoming carboplatin resistance in human ovarian cancer. We cultured the carboplatin-resistant SKOV-3 cells in vitro until the exponential growth phase and then treated with different concentrations of C. militaris for 24, 48, and 72 hours. We performed cell proliferation assay, cell morphological change assessment using transmission electron microscopy, apoptosis assay, and immunoblotting to measure the protein expression of caspase-3 and -8, poly (ADP-ribose) polymerase (PARP)-1, B-cell lymphoma (Bcl)-2, and activating transcription factor 3 (ATF3)/TP53 signaling-related proteins. As a result, C. militaris reduced the viability of carboplatin-resistant SKOV-3 and induced morphological disruptions in a dose- and time-dependent manner. The gene expression profiles indicated a reprogramming pattern of the previously known and unknown genes and transcription factors associated with the action of TCTN3 on carboplatin-resistant SKOV-3 cells. We also confirmed the C. militaris-induced activation of the ATF3/TP53 pathway. Immunoblotting indicated that cotreatment of C. militaris and carboplatin-mediated ATF3/TP53 upregulation induced apoptosis in the carboplatin-resistant SKOV-3 cells, which are involved in the serial activation of pro-apoptotic proteins, including Bcl-2, Bax, caspases, and PARP-1. Further, when the ATF3 and TP53 expression increased, the CHOP and PUMA expressions were upregulated. Consequently, the upregulated CHOP/PUMA expression activated the positive regulation of the apoptotic signaling pathway. In addition, it decreased the Bcl-2 expression, leading to marked ovarian cancer cells sensitive to carboplatin by enhancing apoptosis. We then corroborated these results using in vivo experiments. Taken together, C. militaris inhibits carboplatin-resistant SKOV-3 cell proliferation and induces apoptosis possibly through ATF3/TP53 signaling upregulation and CHOP/PUMA activation. Therefore, our findings provide new insights into the treatment of carboplatin-resistant ovarian cancer using C. militaris.

Abstract
Colorectal cancer is one of the leading causes of cancer related death due to a poor prognosis. In this study, we investigated the effect of Gomisin G on colon cancer growth and examined the underlying mechanism of action. We found that Gomisin G significantly suppressed the viability and colony formation of LoVo cells. Gomisin G reduced the phosphorylation level of AKT implying that Gomisin G suppressed the PI3K-AKT signaling pathway. Gomisin G also induced apoptosis shown by Annexin V staining and an increased level of cleaved poly-ADP ribose polymerase (PARP) and Caspase-3 proteins. Furthermore, Gomisin G remarkably triggered the accumulation of cells at the sub-G1 phase which represents apoptotic cells. In addition, the level of cyclin D1 and phosphorylated retinoblastoma tumor suppressor protein (Rb) was also reduced by the treatment with Gomisin G thus curtailing cell cycle progression. These findings show the suppressive effect of Gomisin G by inhibiting proliferation and inducing apoptosis in LoVo cells. Taken together, these results suggest Gomisin G could be developed as a potential therapeutic compound against colon cancer.

Abstract
Hepatocellular carcinoma (HCC) is frequently metastatic once diagnosed and less likely to respond to curative surgery, emphasizing the need for the development of more sensitive and effective diagnostic and therapeutic strategies. Epithelial cell adhesion molecule (EpCAM) is deemed as the biomarker of cancer stem cells (CSCs), which are mainly responsible for the recurrence, metastasis and prognosis of HCC. In this study, we discuss the use of mitoxantrone (MX), an antitumor drug and a photosensitizer, for designing upconversion nanoparticle-based micelles grafted with the anti-EpCAM antibody, for dual-modality magnetic resonance/upconversion luminescence (MR/UCL)-guided synergetic chemotherapy and photodynamic therapy (PDT). The obtained micelles exhibit good biocompatibility, high specificity to HCC cells and superior fluorescent/magnetic properties in vitro. In vivo results demonstrate that the targeted micelles exhibited much better MR/UCL imaging qualities compared to the nontargeted micelles after the intravenous injection. More importantly, PEGylated UCNP micelles loaded with MX and grafted with anti-EpCAM antibody, denoted as anti-EpCAM-UPGs-MX, showcased the most effective synergetic antitumor efficacy compared with other treatment groups both in vitro and vivo. The remarkable antitumor effect, coupled with superior simultaneous dual-modality MR/UCL imaging as well as good biocompatibility and negligible toxicity, makes the UPG micelles promising for future translational research in HCC diagnosis and therapy.

Abstract
The ubiquitous transcription factor, NF-κB, has been reported to inhibit apoptosis and induce drug resistance in cancer cells. Cordyceps militaris extract (CME) is involved in the regulation of the NF-κB signaling pathway. However, the detailed role of CME in the suppression of the NF-κB signaling pathway is unclear. We found that CME dose-dependently inhibited tumor necrosis factor-α (TNF-α)-induced NF-κB activation in TK-10 human renal cell carcinoma. CME prevented NF-κB from translocating to the nucleus, which resulted in the downregulation of GADD45B, upregulation of MKK7, and phosphorylation of JNK (p-JNK). The increased activation of Bax led to pronounced CME-induced apoptosis, which occurred through caspase-3. Furthermore, the siRNA-mediated knockdown of GADD45B inhibited MKK7 expression, whereas the siRNA-mediated inhibition of MKK7 downregulated p-JNK and the JNK inhibitor, SP600125, inhibited Bax expression. Thus, these results indicated that CME inhibited the activation of GADD45B via the inhibition of NF-κB activation, which upregulated the MKK7-JNK signaling pathway to induce apoptosis in TK-10 cells. Thus, this study reveals a novel anticancer function of CME.

Abstract
Aripiprazole (ARP) is an atypical anti-psychotic drug widely used to treat schizophrenia and bipolar disorder. The pharmacological effects of ARP on cancer cells are still poorly understood. In this study, anti-cancer effects of ARP on various malignant tumor cells and its molecular mechanism were further carefully examined by using cell proliferation assay, xenograft mouse model, immunoblotting analysis, migration assay, luciferase reporter gene assay, kinase assay, and overexpression strategy. Treatment with ARP induced cytotoxicity in U251 glioma cells, MKN-1 gastric adenosquamous carcinoma cells, and CT26 colon carcinoma cells. ARP suppressed cell proliferation of LN428, MDA-MB-231, and HEK293 cells. Pro-apoptotic factors active caspase-3, -8, and -9, as well as p53, were upregulated, whereas the protein and mRNA levels of anti-apoptotic factor B-cell lymphoma 2 (Bcl-2) decreased. In agreement with the in vitro results, ARP compound also significantly suppressed the growth of tumor masses formed by injecting CT26 colon cancer cells into mice. ARP treatment also effectively decreased the migratory ability of U251 glioma cells by downregulating metalloproteinase-9. Levels of phosphorylated Src, phosphorylated phosphatidylinositide 3-kinase (PI3K), and phosphorylated signal transducer and activator of transcription 3 (STAT3) were significantly decreased following ARP treatment. ARP compound reduced the kinase activity of Src. Our studies suggest that Src may be an important target molecule linked to the antitumor effects of ARP.

Abstract
Cordyceps militaris is used widely as a traditional medicine in East Asia. Although a few studies have attempted to elucidate the anticancer activities of C. militaris, the precise mechanism of C. militaris therapeutic effects is not fully understood. We examined the anticancer activities of C. militaris ethanolic extract (Cm-EE) and its cellular and molecular mechanisms. For this purpose, a xenograft mouse model bearing murine T cell lymphoma (RMA) cell-derived cancers was established to investigate in vivo anticancer mechanisms. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay, immunoblotting analysis, and flow cytometric assay were employed to check in vitro cytotoxicity, molecular targets, and proapoptotic action of Cm-EE. Interestingly, cancer sizes and mass were reduced in a C. militaris-administered group. Levels of the phosphorylated forms of p85 and AKT were clearly decreased in the group administered with Cm-EE. This result indicated that levels of phosphoglycogen synthase kinase 3β (p-GSK3β) and cleaved caspase-3 were increased with orally administered Cm-EE. In addition, Cm-EE directly inhibited the viability of cultured RMA cells and C6 glioma cells. The number of proapoptotic cells was significantly increased in a Cm-EE treated group compared with a control group. Our results suggested that C. militaris might be able to inhibit cancer growth through regulation of p85/AKT-dependent or GSK3β-related caspase-3-dependent apoptosis.
