Abstract

Cancer is one of the leading causes of deaths worldwide. Compounds derived from traditional Chinese medicines have been an important source of anticancer drugs and adjuvant agents to potentiate the efficacy of chemotherapeutic drugs and improve the side effects of chemotherapy. Herba Epimedii is one of most popular herbs used in China traditionally for the treatment of multiple diseases, including osteoporosis, sexual dysfunction, hypertension and common inflammatory diseases. Studies show Herba Epimedii also possesses anticancer activity. Flavonol glycosides icariin and icariside II are the main bioactive components of Herba Epimedii. They have been found to possess anticancer activities against various human cancer cell lines in vitro and mouse tumor models in vivo via their effects on multiple biological pathways, including cell cycle regulation, apoptosis, angiogenesis, and metastasis, and a variety of signaling pathways including JAK2-STAT3, MAPK-ERK, and PI3k-Akt-mTOR. The review is aimed to provide an overview of the current research results supporting their therapeutic effects and to highlight the molecular targets and action mechanisms.

Summary

Introduction

Cancer is a complex genetic disease involving abnormal cell growth and is continue to be one of the major causes of deaths in both developed and developing countries [1]. Herba Epimedii has been shown to exert anticancer effect on cancer cell lines in vitro and in[16]. Epimedii mouse tumor [17].has been shown to exert anticancer effect on cancer cell lines in vitro and in vivo in mouse tumor model [17]. Icariin was reported to exhibit activity [28,29] and atherosclerosis [30]. Icariin was reported to exhibit anticanceranticancer activity against a againstofahuman series of human series cancer cellcancer lines. Cerebral of bone marrow derived stromal cells [32] It shows protective effects on cognitive deficits [33] and ischemia-reperfusion injury [34]. Icariside II has been demonstrated to possess cytotoxic and cytostatic activities cancer cell lines.
