Cancer is the most common cause of death in Japan. Fundamental and clinical studies on cancer were conducted from the viewpoint of Western medicine so far. However, a sustained complete remission has not been achieved yet. In order to alleviate the side effects of anticancer drugs, some traditional herbal medicines (Kampo medicines) have been prescribed to cancer patients. We have been studying on antitumor substances in medicinal herbs and found an antitumor medicinal herb named Rhus verniciflua (lacquer, Urushi in Japanese). To investigate the antitumor effect in vitro, a plant extract mixture was prepared from six medicinal herbs containing lacquer. The plant extract mixture containing lacquer (Rv-PEM) inhibited the proliferation of several mouse and human tumor cell lines. Rv-PEM had more potent inhibitory effect on the proliferation of human leukemia cell lines (MOLT-3, KG-1) than on other tumor cell lines. The IC50 values of Rv-PEM on MOLT-3 and KG-1 cells were 0.208 and 0.293 mg/mL, respectively. After treating Rv-PEM to the tumor cells, DNA fragmentation and Caspase-3 and -9 activity increased in the treated cells. The mechanisms of the inhibitory proliferation activity of Rv-PEM would involve apoptosis of human leukemia cells (MOLT-3, KG-1, K-562) by the mitochondrial pathway.

To investigate the effects of the coexistence of aflatoxin B1 (AFB1) and protein malnutrition in rat liver, weanling rats were fed either normal protein diet (20% protein), low-protein (PEM) diet (5%), normal protein diet + 40 ppb AFB1, or low-protein diet + 40 ppb AFB1. After 8 weeks, biomarkers of hepatic functions and oxidative stress, caspase-3 activity, and tumor suppressor protein 53 (p53) were determined spectrophotometrically. Randomly amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) was employed to determine genomic alterations among the groups. Coexistence of aflatoxicosis and PEM significantly decreased glutathione, glutathione-S-transferase, glutathione peroxidase, and superoxide dismutase, while it increased peroxidase and catalase. RAPD-PCR showed genomic alterations that were associated with significant increases in p53 level and caspase-3 activity in rats fed PEM diet + AFB1. In conclusion, the coexistence of aflatoxicosis and protein malnutrition induced oxidative stress with concomitant genomic alterations in the liver of weanling rats.
