Aqueous Viscum album L. extracts are widely used in complementary cancer medicine. Hydrophobic triterpene acids also possess anti-cancer properties, but due to their low solubility they do not occur in significant amounts in aqueous extracts. Using cyclodextrins we solubilised mistletoe triterpenes (mainly oleanolic acid) and investigated the effect of a mistletoe whole plant extract on human acute myeloid leukaemia cells in vitro, ex vivo and in vivo. Single Viscum album L. extracts containing only solubilised triterpene acids (TT) or lectins (viscum) inhibited cell proliferation and induced apoptosis in a dose-dependent manner in vitro and ex vivo...

BACKGROUND: Macrophages are highly versatile cells that play an important role in tumour microenvironment. Tumour associated macrophages (TAMs) have been linked to both, good or bad prognosis of several cancer types depending on their number, composition and polarization. Viscum album lipophilic extract (VALE) contains several pentacyclic triterpenes known to modulate the activity of monocytes and other immune cells and to exhibit anticancer properties. In our in vitro study, we investigated the effect of tumour cell lines on macrophage polarization and monocyte chemotactic transmigration and examined the modulatory potential of VALE and its predominant triterpene oleanolic acid (OA)...

BACKGROUND AND AIM: Extracts of Viscum album (European mistletoe) have immune-stimulatory and cytotoxic effects, with trials showing a well-established effect on the quality of life and prolonged survival in patients with advanced pancreatic cancer. Regression of tumours following intratumoural injection with Viscum album extract has been documented in individual cases. However, its influence on colon polyps has not been investigated. CASE PRESENTATION: We present the case of a 78-year-old Caucasian male who had undergone hemi-colectomy for a stage IIIC colon cancer but who refused adjuvant chemotherapy...

BACKGROUND: Malignant pleural effusion is a common problem in patients with solid tumours. It has a significant impact on quality of life, and, hence, there is a substantial need to investigate new agents to treat it. PATIENTS AND METHODS: This is a prospective randomised controlled study, including patients with symptomatic recurrent malignant pleural effusion of different primaries. Patients were randomised into two groups: the first group received five ampoules of mistletoe preparation with defined lectin content (Viscum Fraxini-2, ATOS Pharma) diluted in 10 cc glucose 5% solution...

Background. Osteosarcoma is a highly malignant bone tumour. After the second relapse, the 12-month postrelapse disease-free survival (PRDFS) rate decreases below 20%. Oral Etoposide is often used in clinical practice after surgery as an "adjuvant" outside any protocol and with only limited evidence of improved survival. Viscum album fermentatum Pini (Viscum) is an extract of mistletoe plants grown on pine trees for subcutaneous (sc) injection with immunomodulatory activity. Methods. Encouraged by preliminary findings, we conducted a study where osteosarcoma patients free from disease after second metastatic relapse were randomly assigned to Viscum sc or Oral Etoposide...

Plant lectins, a group of highly diverse carbohydrate-binding proteins of non-immune origin, are ubiquitously distributed through a variety of plant species, and have recently drawn rising attention due to their remarkable ability to kill tumour cells using mechanisms implicated in autophagy. In this review, we provide a brief outline of structures of some representative plant lectins such as concanavalin A, Polygonatum cyrtonema lectin and mistletoe lectins. These can target autophagy by modulating BNIP-3, ROS-p38-p53, Ras-Raf and PI3KCI-Akt pathways, as well as Beclin-1, in many types of cancer cells...

BACKGROUND: Viscum album L extracts (VAE, mistletoe) and isolated mistletoe lectins (ML) have immunostimulating properties and a strong dose-dependent cytotoxic activity. They are frequently used in complementary cancer treatment, mainly to improve quality of life, but partly also to influence tumour growth, especially by injecting VAE locally and in high dosage. The question is raised whether these higher dosages can induce any harm or immunosuppressive effects. METHODS: Systematic review of all experiments and clinical studies investigating higher dosages of VAE in animals and humans (Viscum album > 1 mg in humans corresponding to > 0...

Extracts from the European mistletoe plant Viscumalbum have been studied for decades for their direct and indirect anticancer activity. Therefore, scientists were interested in identifying the active compound (mistletoe lectin) in these extracts and making it available as a highly purified molecule for drug development. Recombinant mistletoe lectin (INN: aviscumine) was produced in Escherichiacoli. It has been shown to have immunomodulatory and cytotoxic activity in invitro and in animal models and can target tumour cells...

Treating a patient suffering from an advanced oral cavity carcinoma by peritumoural injections of mistletoe preparation resulted in a surprising partial response. At the same time an early metastasis, located at the kidney, however remained unaffected. The main difference in treatment being peritumoural versus systematic application supports the hypothesis of immune surveillance. The impact of mistletoe extract in direct contact with the tumour tissue might be explained as activation of macrophage polarization followed by induced cytotoxicity...

Micro-RNAs (miRNAs) are small RNA molecules that regulate the expression of genes involved in development, growth, proliferation and apoptosis. In cancer several miRNAs have been functionally classified as oncogenes or tumour suppressers or act to regulate transcription factors, like nuclear factor kappa B and NF-E2–related factor 2, in cancers such as leukaemia, breast and colorectal. Therefore, it has been proposed that manipulating miRNA regulation may be a novel avenue for developing efficient therapies against cancer...

Today cancer treatment is not only a question of eliminating cancer cells by induction of cell death. New therapeutic strategies also include targeting the tumour microenvironment, avoiding angiogenesis, modulating the immune response or the chronic inflammation that is often associated with cancer. Furthermore, the induction of redifferentiation of dedifferentiated cancer cells is an interesting aspect in developing new therapy strategies. Plants provide a broad spectrum of potential drug substances for cancer therapy with multifaceted effects and targets...

Malignant ascites is a frequent complication in oncological diseases. There are no standard therapies for any primary tumour. We report the case of a woman, aged 49 years at the time of primary diagnosis, who suffered from recurrent ascites resulting from liver metastasis of breast cancer. Based on the literature and former experience of our department, mistletoe extract was repeatedly applied intraperitoneally at the occasion of decompressive punctures. The further course of the disease suggests a significant role of mistletoe in achieved symptom control, which also resulted in a considerable improvement in quality of life...

To date most pharmacological studies on mistletoe (Viscum album L.) have focused on the therapeutic properties of its polar extracts. This study examined the non-polar constituents of Viscum album and their biological activities. Supercritical CO(2) extraction coupled with gas chromatography/mass spectrometry (GC/MS) was used to selectively extract and identify compounds in Viscum album leaves. Several non-polar classes of compounds were identified in the extract. In addition, a volatile fraction was identified that contained several novel terpene molecules...

This study investigates the effects of mistletoe lectin-I (ML-I) on melanoma growth and spread in vivo. The human melanoma cell line MV3 was xenografted into severe combined immunodeficient mice and vehicle solution or purified ML-I was administered at 30, 150 and 500 ng per kg body weight (20 mice per group) daily. After 19 days, mice were killed, primary tumours (PTs) and lungs were dissected out, and tumour weights, number of lung metastases (LMs), number of tumour-infiltrating dendritic cells (DCs), and apoptosis rates in the melanoma cells and in the DCs were assessed...
