Male probasin/SV40 T antigen transgenic rats were fed diets containing 0.1%, 0.02%, or 0.004% Arctiin for 18 weeks. Histopathological evaluation showed that all rats developed adenocarcinoma in the dorsolateral prostate except two rats in the 0.1% group and one rat in the 0.02% group without carcinoma [1]. However, there were no definite treatment-related changes with statistical significance in any parameters for prostate carcinomas measured, including incidences of PIN and adenocarcinoma, and quantitative analysis of histological components in dorsolateral and anterior lobes [1]. Arctiin did not exert significant modifying effect (either promoting or chemopreventive) on prostate carcinogenesis in this model [1].
Small cell carcinomas were found in the dorsolateral prostate of four rats, with no group difference in distribution [1]. Two rats with extremely large prostates (each in the 0.02% arctiin and control groups) developed small cell carcinoma [1]. The average percentage of PIN, well-differentiated adenocarcinoma, and moderately differentiated adenocarcinoma in dorsolateral and anterior lobes showed no significant differences among groups [1]. |

| Animal Protocol |
Heterozygous male SV40 T antigen transgenic rats (6 weeks old) were used [1]. Arctiin (purity >97%) was mixed into powdered soybean-free basal diet at concentrations of 0.1%, 0.02%, or 0.004% [1]. The control group received soybean-free basal diet alone [1]. Animals were housed 2 per cage on wood-chip bedding in an air-conditioned room at 23±2°C and 60±10% humidity, with diet and tap water available ad libitum [1]. The treatment duration was 18 weeks [1]. Body weight and food consumption were recorded biweekly [1]. At the end of week 18, all surviving rats were killed under ether anesthesia [1]. At autopsy, prostates were removed and fixed in 10% neutral buffered formalin; livers and kidneys were excised, weighed, and fixed [1]. After 48 hours of fixation, the dorsolateral and anterior lobes were carefully dissected, weighed, and 2-3 mm thick slices were made from each lobe, then embedded in paraffin for histopathological examination of hematoxylin and eosin stained sections [1]. Neoplastic lesions of the prostate were classified as prostatic intraepithelial neoplasia (PIN), well-differentiated adenocarcinoma, moderately differentiated adenocarcinoma, or poorly differentiated adenocarcinoma [1]. Each prostatic lobe was scored and the percentage area corresponding to each pathological stage was quantified using an image processor for analytical pathology [1].

| Additional Infomation |
Arctiin is a glycoside and lignan. Arctiin has been reported in Saussurea involucrata, Saussurea salsa, and other organisms for which data are available. See also: Lignans (subclasses of lignans); Burdock fruit (part); Burdock root (part).
Arctiin is a plant lignan belonging to the class of phytoestrogens, which are nonsteroidal substances with weak estrogenic activity [1]. Phytoestrogens are 1000-fold less potent than estradiol but have similar relative affinity for estrogen receptor, acting as ER partial antagonists [1]. Arctiin has been found to influence sex hormone metabolism, protein synthesis, and steroid biosynthesis [1]. It is converted by human intestinal bacteria to estrogenic and antiestrogenic substances [1]. Arctiin induces drug metabolism enzymes such as CYP1A2 in rat liver [1]. In the present study, Arctiin showed no definite effects on prostate carcinogenesis in SV40 T antigen transgenic rats, although a weak inhibitory tendency was observed in high dose groups [1]. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
