Nicoletti M. The Anti-Inflammatory Activity of Viscum album. PLANTS (BASEL, SWITZERLAND) 2023; 12:1460.

Abstract
The therapeutic story of European mistletoe (Viscum album L.) presents a seesawing profile. In ancient times, this hemiparasitic plant was considered a panacea and even to be endowed with exceptional beneficial properties. In more recent times, despite its multiple uses in traditional medicines, some parts of the plant, in particular the berries, were considered poisonous and dangerous, including concerns of cytotoxicity, which spread serious suspicion on its medicinal utility. However, since the last century, medical interest in mistletoe has come back in force due to its utilization in clinical cancer treatments, based on its selective action on tumor cells. In Central Europe, the hydro-alcoholic extracts of European mistletoe register a relevant and continuous utilization in anthroposophic medicine, which is a holistic system that includes the utilization of phytomedicinal substances. In Switzerland and Germany, most physicians and patients use these products as complementary therapy in oncological treatments. However, despite its increasing use in this field, the results of mistletoe's use are not always convincing, and other aspects have appeared. Nowadays, products that contain mistletoe are utilized in several fields, including diet, phytotherapy, veterinary medicine and homeopathy, but in particular in cancer therapies as coadjuvant factors, in consideration of several positive effects including effects in the improvement of quality-of-life conditions and reinforcement of the immune system. In this review, based on the understanding of the association between cancer and inflammation, we propose a relationship between these recent uses of mistletoe, based on its antioxidant properties, which are supported by phytochemical and pharmacological data. The unicity of mistletoe metabolism, which is a direct consequence of its hemiparasitism, is utilized as a key interpretation element to explain its biological properties and steer its consequent therapeutic uses.

Abstract
Safety of aviscumine by subcutaneous route was assessed in patients with advanced cancer refractory to chemotherapy. Patients with progressive disease received escalating doses twice weekly. Treatment of the accrued 26 patients (10 colorectal cancer (CRC), 6 soft tissue sarcoma (STS), 5 melanoma (MM), 5 others) was well tolerated without substance-related grade 3 or 4 toxicities. Grade 1/2 toxicities were predominantly injection site reactions. Aviscumine lacked dose-limiting toxicity (DLT) up to a maximal dose of 10 ng/kg. An increase of interleukin-1 beta and interferon-gamma from baseline was seen in the patient's plasma between the 1st and 11th injection. Highest release of both cytokines was in the dose range of 4-5.9 ng/kg. Interferon-gamma was not detected after doses higher than 6 ng/kg. Eight patients (5 CRC, 1 MM, 1 STS, 1 RCC) had disease stabilisation for 79-250 days (median122 days) associated with an increase of interleukin (IL)-1 beta and interferon (IFN)-gamma. Aviscumine was well tolerated and appeared to possess clinical activity at a biologically active dose between 4 and 6 ng/kg.

Abstract
BACKGROUND Recently, there have been extensive efforts to evaluate the chemopreventive role of substances present in natural products. The aim of this study was to examine the effects of the main groups of compounds (salicylalcohol derivates, flavonoids, proanthocyanidins), and salicin isolated from willow bark extract BNO 1455 on proliferation and apoptosis in human colon and cancer cells. METHODS We used human colon cyclooxygenase-2 (COX-2)-positive HT 29 and (COX-2)-negative HCT 116 or lung COX-2 proficient A 549 and low COX-2 expressing SW2 cells. After treatment for 72 h with various concentrations of single substances and acetylsalicylic acid (ASA) as control, inhibition of cell growth and cytotoxicity were measured by colorimetric WST-1 assay and propidium iodide uptake by flow cytometry, respectively. Apoptotic cells were identified by annexin V adhesion using flow cytometry. RESULTS Studies on dose-dependent effects of BNO 1455 and its fractions showed anti-proliferative activity of all compounds with 50% maximal growth inhibitory concentrations (GI(50)) between 33.3 and 103.3 microg/ml for flavonoids and proanthocyanidins fractions and 50.0-243.0 microg/ml for salicylalcohol derivates and extract. Apoptosis induction was confirmed by annexin V adherence and analysis of cell morphology based on light scattering characteristics using flow cytometry in all cell lines at GI(50). CONCLUSIONS We showed that willow bark extract BNO 1455 an its fractions inhibit the cell growth and promote apoptosis in human colon and lung cancer cell lines irrespective of their COX-selectivity.

Abstract
BACKGROUND Mistletoe extracts are widely used in cancer patients due to their cytostatic and immunomodulatory effects. Essential components include mistletoe lectins which act as biomodulators with proinflammatory and apoptosisinducing effects. This study investigates the acute and longterm effects of standardized mistletoe extract (Iscador(R) M spec 5 mg) on thymocyte subpopulations and peripheral T-cells using a murine (Balb/c) model. MATERIALS AND METHODS Using cell surface CD4/CD8 staining and flow cytometry, we followed the changes in CD4-CD8- double-negative (DN), CD4(+)CD8(+) double-positive (DP) and CD4(+) or CD8(+) single-positive (SP) T-cells 24 h after single or repeated injections of 3 different dilutions (1:12, 1:60, 1:300) corresponding to 2.1, 0.42 and 0.08 mg/kg of Iscador. Thymocyte apoptosis was detected by flow cytometry using Annexin V and propidium iodide. RESULTS 24 h after a single injection of the 2 lower doses, the number of DN thymocytes increased significantly with an enhanced ratio of apoptotic cells. Following administration of the lowest dose, in peripheral blood the CD4(+)/CD8(+) ratio was elevated. In the long-term trial, Balb/c mice were treated twice a week with 3 different doses of Iscador +/- 20 mg/kg of dexamethasone (DX), resulting in significantly enhanced DN thymocytes and elevated levels of apoptotic cells after treatment with the 2 lower doses. Iscador also inhibited the DX-induced reduction in the thymic DN cell count, as well as the DX-induced decrease in the CD4(+)/CD8(+) ratio and CD4(+) in the peripheral blood. CONCLUSION Our results suggest that standardized mistletoe extract modulates proliferation and apoptosis of thymocytes in a dose-dependent manner and may act lymphoprotective during DX treatment.

Abstract
Viscum album agglutinin-I (VAA-I) is a potent inducer of cell apoptosis and possesses anti-tumoral activity. Using PLB-985 and chronic granulomatous disease (X-CGD) cells, which lack expression of gp91(phox), VAA-I was found to induce apoptosis in both cell lines as assessed by cytology, DNA laddering and degradation of the cytoskeletal protein gelsolin. Both cell lines expressed caspase-3 and -8 and VAA-I activated these caspases. We demonstrated that lamin B(1) is a novel target to VAA-I and its degradation was reversed by a pan-caspase inhibitor and by a caspase-6, but not a caspase-8, inhibitor.

Abstract
Hyperforin (HP) is an abundant component of St John's wort with antibiotic and antidepressive activity. We report here the ability of HP and that of polyphenolic procyanidin B2 (PB-2) to inhibit the growth of leukemia K562 and U937 cells, brain glioblastoma cells LN229 and normal human astrocytes. HP inhibited the growth of cells in vitro with GI(50) values between 14.9 and 19.9 microM. The growth inhibitory effect of PB-2 was more pronounced in leukemia cell lines K562 and U937, the GI(50) concentrations being about 12.5 microM established after 48 h incubation differed significantly (P<0.05) from those of LN229 and normal human astrocytes (103.1 and 96.7 microM), respectively. Further, HP and hypericin (HY) (a naphthodianthrone from St John's wort) acted synergistically in their inhibitory effect on leukemic (K562, U937) cell growth. Cell death occurred after 24 h treatment with HP and PB-2 by apoptosis. A dose-dependent loss of membrane phospholipid asymmetry associated with apoptosis was induced in all cell lines as evidenced by the externalization of phosphatidylserine (PS) and morphological changes in cell size and granulosity by scatter characteristics. In leukemia U937 cells, HP increased the activity of caspase-9 and caspase-3 and in K562 cells caspase-8 and caspase-3. In addition, the broad spectrum caspase inhibitor z-VAD-fmk inhibited both the appearance of PS exposure and the activation of caspases, illustrating the functional relevance of caspase activation during HP-induced apoptosis. Cytocidal effects of HP and its cooperation with HY on tumor growth inhibition in a synergistic manner make the St John's wort an interesting option in cancer warranting further in vitro and in vivo investigation.

Abstract
Mistletoe extracts are used as alternative cancer treatment in addition to standard chemotherapy and radiation treatment and have an immunostimulatory and pain-relieving effect. A direct antitumour effect of mistletoe extracts against tumour cells of lymphoid origin has been linked to the D-galactoside-specific mistletoe lectin I. In this study, we investigated the cellular effect of bacterially expressed, recombinant mistletoe lectin alone or in combination with ionising radiation in a genetically defined p53-wild-type and p53-deficient E1A/ras-transformed murine tumour cells system. Downregulation of the proliferative activity and cell killing by recombinant mistletoe lectin occurred in a clear dose response (0.1-1 ng ml(-1)). Induction of apoptosis was p53-independent, but apoptosis-associated factor-1-dependent. Cellular treatment with lectin in combination with ionising radiation resulted in both p53-wild-type and p53-deficient tumour cells in an at least additive, antiproliferative effect and enhanced activation of caspase-3. Combined treatment with ionising radiation and lectin revealed a similar cytotoxic effect in human, p53-mutated adenocarcinoma cells. Thus, recombinant mistletoe lectin alone and in combination with ionising radiation bypasses often prevalent apoptotic deficiencies in treatment-resistant tumour cells.

Abstract
Galactoside-specific plant lectin, Viscum album agglutinin-I (VAA-I) has been shown to act as a biomodulator with proinflammatory and apoptosis-inducing effects, however its cellular targets and mechanism of immunobiological action in vivo are less well understood. Therefore, in the present work the short- and long-term in vivo effects of VAA-I on thymocyte subpopulations and peripheral T cells were tested using a murine (Balb/c) model. Cell surface CD4/CD8 staining and flow cytometry allowed us to follow the changes of thymocyte subpopulations: CD4-CD8- double negative (DN), CD4+CD8+ double positive (DP), CD4+ or CD8+ single positive (SP) and mature peripheral T cells after single or repeated injections with low doses of VAA-I. The apoptosis of the cells was detected by flow cytometry using propidium iodide (PI) and Annexin V staining. To detect the short-term effects of the lectin, the animals were investigated 24 h after a single injection of 1 or 30 ng/kg body weight (BW) VAA-I+/-1 mg/kg Dexamethasone (DX). The total number of mature CD8+ SP thymocytes increased significantly with an enhancement of the ratio of apoptotic cells. In contrast, in the blood samples an elevated CD4/CD8 ratio was found. In the next trial, Balb/c mice were treated twice weekly with 1 or 30 ng/kg VAA-I+/-1 mg/kg DX for 3 weeks. The total cell count of thymocytes showed significant increases after both doses of VAA-I, but an elevated percentage of apoptotic cells was found only after treatment with 30 ng/kg VAA-I. SP thymocytes revealed higher increases in lectin-induced apoptosis than DN or DP cells. In addition, both lectin doses significantly inhibited the DX-induced reduction of all thymocyte subpopulations investigated. In conclusion, our data suggest that VAA-I is able to modulate the maturation of thymocytes in vivo.

Abstract
A method for the analysis of the rViscumin heterodimer (recombinant mistletoe lectin) based on two-dimensional (2-D) polyacrylamide gel electrophoresis and mass spectrometry was developed and used for quality control concerning purity and homogeneity of the recombinant protein processed under Good Manufacturing Practice (GMP) conditions. A series of spots with different pI-values in the pH-gradient of both rViscumin A- and B-chain were observed independently from the experimental conditions like urea concentration, heat treatment or the use of cysteine alkylating agents. Comparative studies of the major spots using matrix assisted laser desorption/ionization-mass spectrometry (MALDI-MS), liquid chromatography-electrospray ionization (LC-ESI)-MS and LC-ESI-tandem MS (MS/MS) after tryptic in-gel digestion resulted in a sequence coverage of 92% for the A-chain and 95% for the B-chain. No molecular differences like common chemical or post-translational modifications or nonenzymatic deamidation were found to cause the different charge values of the separated spots. Therefore, these protein spots were extracted from the 2-D gel and separated again by 2-D gel electrophoresis (termed Re-2-DE). Each of the single spots tested in the Re-2-DE experiment split up in the same heterogeneous pattern concerning the pI-values. We suggest that the observed charge variants of rViscumin are the result of conformational protein variants, existing in an equilibrium during sample preparation and/or isoelectric focusing and are not caused from microheterogeneity in the primary structure of rViscumin.
