Enzootic bovine haematuria, caused by long-term ingestion of ferns, is a chronic disease of hill cattle characterized by neoplastic lesions in the urinary bladder. Objectives of this study were to investigate the toxicity potential of long-term feeding of the fern Dryopteris nigropalaceae and effect

BACKGROUND
Dryopteris crassirhizoma has been traditionally used for the treatment of tapeworm infestation, the common cold and cancer in Korea, China and Japan. Despite various pharmacological properties of Dryopteris crassirhizoma, there is no available information about the safety of Dryopteris

Aspidin PB is a natural product extracted from Dryopteris fragrans (L.) Schott, which has been characterized for its various biological activities. We reported that aspidin PB induced cell cycle arrest and apoptosis through the p53/p21 and mitochondria-dependent pathways in human osteosarcoma cells.

Aspidin BB, an effective phloroglucinol derivative from Dryopteris fragrans (L.) Schott, has been previously reported to exert high biological activities. In this study, we analyzed the underlying mechanisms of aspidin BB on human ovarian cancer cell line, HO-8910. Aspidin BB significantly inhibited
Dryofragin inhibits the migration and invasion of human osteosarcoma U2OS cells by suppressing MMP-2/9 and elevating TIMP-1/2 through PI3K/AKT and p38 MAPK signaling pathways.
