Effects of homeopathic preparations on human prostate cancer growth in cellular and animal models.

The use of dietary supplements for various ailments enjoys unprecedented popularity. As part of this trend, Sabal serrulata (saw palmetto) constitutes the complementary treatment of choice with regard to prostate health. In homeopathy, Sabal serrulata is commonly prescribed for prostate problems ranging from benign prostatic hyperplasia to prostate cancer.

Cancer-related overexpression of the peripheral-type benzodiazepine receptor and cytostatic anticancer effects of Ginkgo biloba extract (EGb 761).

The peripheral-type benzodiazepine receptor (PBR) is an 18-kDa high affinity drug- and cholesterol-binding protein that is involved in various cell functions, including cell proliferation and apoptosis. PBR was shown to be overexpressed in certain types of malignant human tumors and cancer cell lines, correlating with enhanced tumorigenicity and cell proliferation rates. The present study was conducted in order to further define the role of PBR in cancer and to extend our recent findings regarding the possible anticancer effects of the standardized Ginkgo biloba extract EGb 761.

Common gene targets of Ginkgo biloba extract (EGb 761) in human tumor cells: relation to cell growth.

The standardized extract of Ginkgo biloba leaves (EGb 761) has been shown to inhibit aggressive human breast cancer cell proliferation both in vitro and in vivo. These results were extended to human glioma and hepatoma cells in vitro suggesting that EGb 761 may have a more widespread application for tumor growth control. To understand the mechanism by which EGb 761 acts to inhibit cell proliferation, we investigated the effects of EGb 761 on human breast cancer, glioma and hepatoma cell transcriptomes by means of various large-scale DNA array techniques.
