Ankaferd Blood Stopper induces apoptosis and regulates PAR1 and EPCR expression in human leukemia cells

Antineoplastic Effects of Ankaferd Hemostat

Objectıve. Ankaferd hemostat (ABS; Ankaferd Blood Stopper®) contains standardized plant extracts comprising Alpinia officinarum, Glycyrrhiza glabra, Thymus vulgaris, Urtica dioica, and Vitis vinifera. ABS especially was recognized for its hemostatic effect; however, antineoplastic role of ABS was identified during the last decade. The aim of this paper is to review the molecular basis and associated clinical implications of the ABS as a topical antineoplastic agent. Materials and Methods. Up to June 2022, literature searches were performed using the internet search engines Medline, Google Scholar, and Embase: Ankaferd. PRISMA flow diagram described the Ankaferd search. Results. ABS have important effects in several cellular processes, like control of the cell cycle, apoptosis, angiogenesis, signal transduction, inflammation, immunologic, and metabolic mechanisms. The molecular basis of antineoplastic roles of ABS depends on its proteomics, metabolomics, and transcriptomics features. ABS has antineoplastic effects on solid tumors like colon, bladder, breast, and osteosarcoma cancer cells. Also, ABS effects renal tubular apoptosis and has antitumoral roles on malign melanoma cells. ABS inhibits hematological tumors like myeloma and lymphoid cells. ABS induces apoptosis in retinal cells and has inhibitory effects on mesenchymal stem cells. It has an antiproliferative role on gastrointestinal tumors like hepatocellular carcinoma cells. Moreover, ABS has a treatment supportive role in cancer since it can prevent oxidative DNA damage and decrease the intestinal damage in necrotizing enterocolitis. Furthermore, it has chemopreventive and hepatoprotective features and can be used for prophylaxis and treatment of oral mucositis. Conclusion. ABS alters cell metabolism and cell cycle. ABS has antineoplastic role on cancer cells. The expanding context of ABS compromises anti-infective, antineoplastic, and wound healing features. ABS may also be used for the palliative, adjuvant, neoadjuvant, or supportive use by interventional radiology procedures for the treatment of solid tumors. Future controlled studies are necessary to clarify the pleiotropic role of ABS like antineoplastic, antithrombotic, anti-inflammatory, anti-infective, antifungal, and antioxidative effects.

Rassouli F. Combination of Umbelliprenin and Arsenic Trioxide Acts as an Effective Modality Against T-Cell Leukemia/Lymphoma Cells

Adult T-cell leukemia/lymphoma (ATLL) is a serious blood malignancy with distinct geographical distribution. ATLL patients have a short survival time because of intrinsic chemoresistance and severe immunosuppression. To introduce a novel treatment, we investigated whether umbelliprenin (UMB), a natural coumarin derivative, could improve the toxicity of arsenic trioxide (ATO) on ATLL cells. To determine the viability of MT-2 cells upon treatment with different concentrations of UMB and ATO, alamarBlue assay was applied. Cell cycle analysis was carried out by propidium iodide staining and the expression of candidate genes was assessed by quantitative reverse transcription-polymerase chain reaction. Our findings revealed that combination of UMB and ATO induced considerable cytotoxic effects on ATLL cells. Flow cytometry analysis indicated accumulation of MT-2 cells in the sub G1 phase of the cell cycle after combinatorial treatment. In addition, significant downregulation in BMI-1, CD44, c-MYC, and nuclear factor-κB (REL-A) expression was observed after UMB + ATO administration. Agents with low side effects are potential candidates for novel cancer treatments. We demonstrated, for the first time, that combination of UMB and ATO might be regarded as an effective regimen for ATLL treatment.

A candidate antineoplastic herbal agent for bladder cancer: Ankaferd Blood Stopper

BACKGROUND AND AIMS

Ankaferd Blood Stopper (ABS) was used for in vitro studies of osteosarcoma and colon carcinoma cancer cell lines to reveal the apoptotic and antineoplastic effects. The aim of this study is to evaluate the antineoplastic effect of ABS on bladder cancer cell cultures.

METHODS

We prospectively collected minimum 0.5 cm parts of fresh frozen tumour samples from patients with bladder tumour from 2015 to 2017. Primary bladder cancer cultures were produced from the frozen tumour samples. Two different doses of ABS were used on cancer cell cultures. Viability tests of each cell cultures were performed. Flow cytometry was used for the determination of apoptosis and necroptosis. We also checked the effect of ABS on different stages, grade and variant histology of bladder cancer cells. The results of all cancer cell cultures were compared with their own controls.

RESULTS

This study included 24 patients. Mean age of patients was 66.2 ± 11.7 years (34-83 years), where 19 of them (79.5%) were males and five (20.5%) were females. When we compared the data, we found decreased cancer cell viability ratio in each ABS group compared with their own controls. Necroptosis was observed in the great majority of ABS groups, and necroptosis and apoptosis were observed in some cell cultures.

CONCLUSIONS

In this study, we demonstrated the cytotoxic effect of ABS on bladder cancer cells. The results of this study suggests planning of animal model of bladder cancer for ABS with intravesical application as an antineoplastic agent. In the future, ABS may be a candidate intravesical treatment agent for bladder cancer.

Vitexin isolated from Prosopis cineraria leaves induce apoptosis in K-562 leukemia cells via inhibition of the BCR-ABL-Ras-Raf pathway

OBJECTIVES

Leukemia is one of the severe cancer types all around the globe. Even though some chemotherapeutic drugs are available for treating leukemia, they have various side effects. As an alternative approach, herbal drugs are focused on current research to overcome leukemia. The present work was conducted to investigate the antileukemic mechanism of active phytochemical vitexin, which was isolated from ethno-medicine (Prosopis cineraria leaf) used by traditional healers of West Bengal, India.

METHODS

Antiproliferative mechanisms of selected phyto-compound against K-562 cells were evaluated using cellular uptake, morphological changes, DNA fragmentation, mitochondrial membrane potential and signaling pathways analysis.

KEY FINDINGS

Vitexin exhibited cytotoxicity by reducing mitochondrial membrane potential (32.40%) and causing DNA fragmentation (84.15%). The western blotting study indicated inhibition of cell survival proteins (BCR, ABL, H-RAS, N-RAS, K-RAS and RAF) and expression of apoptotic proteins (p38, BAX and caspase-9) in leukemia cells upon treatment with vitexin.

CONCLUSIONS

Based on the results, presently investigated phyto-compound vitexin could be considered for developing safe and natural drugs to treat leukemia after conducting suitable preclinical and clinical trials.

Pharmacobiological management of hemostasis within clinical backgrounds via Ankaferd hemostat (Ankaferd blood stopper)

Ankaferd hemostat (Ankaferd blood stopper [ABS], Istanbul, Turkey) is a hemostatic agent affecting red blood cell-fibrinogen interactions. ABS has been traditionally used in Anatolia as a hemostatic agent for centuries. ABS contains a standardized combination of the plants namely Glycyrrhiza glabra, Thymus vulgaris, Alpinia officinarum, Vitis vinifera, and Urtica dioica. The hemostatic effect of ABS depends upon the quick promotion of a protein network, particularly fibrinogen gamma, in relation to the erythrocyte aggregation. The aim of this review is to indicate pharmacobiological basis and clinical backgrounds of ABS. Current perspective for using ABS is to provide hemostasis and accelerating wound healing particularly in cases which are difficult to manage. Future controlled trials are needed to elucidate the actions of ABS with in hemostasis, antithrombotic, anti-inflammatory, anti-infective, antifungal, and anti-oxidative effects.

Growth inhibitory activity of Ankaferd hemostat on primary melanoma cells and cell lines

Objective:

Ankaferd hemostat is the first topical hemostatic agent about the red blood cell–fibrinogen relations tested in the clinical trials. Ankaferd hemostat consists of standardized plant extracts including Alpinia officinarum, Glycyrrhiza glabra, Thymus vulgaris, Urtica dioica, and Vitis vinifera. The aim of this study was to determine the effect of Ankaferd hemostat on viability of melanoma cell lines.

Methods:

Dissimilar melanoma cell lines and primary cells were used in this study. These cells were treated with different concentrations of Ankaferd hemostat to assess the impact of different dosages of the drug. All cells treated with different concentrations were incubated for different time intervals. After the data had been obtained, one-tailed T-test was used to determine whether the Ankaferd hemostat would have any significant inhibitory impact on cell growth.

Results:

We demonstrated in this study that cells treated with Ankaferd hemostat showed a significant decrease in cell viability compared to control groups. The cells showed different resistances against Ankaferd hemostat which depended on the dosage applied and the time treated cells had been incubated. We also demonstrated an inverse relationship between the concentration of the drug and the incubation time on one hand and the viability of the cells on the other hand, that is, increasing the concentration of the drug and the incubation time had a negative impact on cell viability.

Conclusion:

The findings in our study contribute to our knowledge about the anticancer impact of Ankaferd hemostat on different melanoma cells.

Bufalin inhibits pancreatic cancer by inducing cell cycle arrest via the c-Myc/NF-κB pathway

ETHNOPHARMACOLOGICAL RELEVANCE

Bufalin, a cardiotonic steroid isolated from toad venom (bufo gargarizans Cantor or B. melanotictus Schneider), has widely demonstrated antitumor effects and exhibits potential antitumor activity in various human cancer cells lines.

AIMS OF THE STUDY

The main characteristic of cancers including pancreatic cancer is the ability of uncontrolled proliferation. The aim of this study is to clarify the underlying mechanism by which bufalin inhibits pancreatic cancer cell proliferation.

MATERIALS AND METHODS

The effect of bufalin on the suppression of tumor growth in vivo was studied in a bioluminescent mouse model generated using the pancreatic cancer cell line BxPC3-luc2 and the cytotoxicity was evaluated in BcPc3 and Sw1990 cells with MTT. Flow cytometry and western blotting analyses were utilized to detect the effect of bufalin on the cell cycle and to detect the cell cycle-related proteins, respectively. Then, a luciferase reporter assay was applied to screen the activity of potent transcription factors following bufalin exposure and their expression was detected by western blotting.

RESULTS

Bufalin suppressed tumor growth in a bioluminescence mouse model generated using BxPC3-luc2 cells and inhibited cell proliferation in vitro through inducing cell cycle arrest at S phase. Bufalin treatment inhibited cyclin D1 and cyclin E1 expression and therefore increased expression of p27, a regulatory molecular that controls cell cycle transition from S to G2 phase. Furthermore, luciferase reporter screening studies revealed that bufalin inhibited the expression and activity of the transcription factors c-Myc and NF-κB, which might cause cell cycle arrest at S phase and the inhibition of cell proliferation.

CONCLUSIONS

Taken together, our results indicate that bufalin can inhibit pancreatic cancer by targeting c-Myc, thus suggesting that the mechanism of c-Myc regulation by bufalin might be worthy of further study regarding its potential as a therapeutic target for pancreatic cancer treatment.
