Gene or Protein evidence |
Simultaneous treatment of human cervix carcinoma HeLa or breast carcinoma MCF-7 cells with MLs isolated from European or Korean mistletoe rendered them more sensitive to induction of apoptosis by TNF. In all supernatants of AM-stimulated cell culture TNF-alpha and IL-6 were found, Indicating activation of cells of the monocyte/macrophage lineage by mistletoe extracts.
Mistletoe extract simultaneously increased the expression of the DNA damage marker proteins, phosphorylated H2A histone family member X (H2A.X), and phosphorylated p38.In addition to tumor growth inhibition, mistletoe extract inhibited lung metastasis in the tumor-bearing mice and cell invasiveness by downregulating the expressions of matrix metalloproteinases (MMPs), urokinase-type plasminogen activator (uPA), uPA receptor, and markers of epithelial-mesenchymal transition (snail and fibronectin). |
Target pathways |
Mistletoe extract targets the STAT3-FOXM1 pathway for its cytotoxic effect. |

Additional information |
Therefore, the objective of this clinical study was to investigate the impact of PS76A2, an aqueous mistletoe extract standardised to the galactoside-specific mistletoe lectin, on QoL by performing a placebo-controlled trial.
As a result, statistically significant effects on QoL were obtained with the medium dose (15 ng ML/0.5 ml).
The treatment difference between the medium dose and placebo with regard to the GLQ-8 sum was 60.8 mm (95% confidence interval: 19.3 to 102.0 mm).
The treatment effect for Spitzer's uniscale between the medium dose and placebo was 16.4 mm (95% confidence interval: 6.3 to 26.6 mm).
The results on QoL were supported by an increase of T helper lymphocytes (CD4+) and the CD4+/CD8+ ratio (p<0.05).
Overall, PS76A2 was well tolerated.
Local reactions at the injection sites occurred dose-dependently, but were mild at the low and medium dose levels. |
