INTRODUCTION Curdione, one of the major sesquiterpene compounds from Rhizoma Curcumae, has been shown to exhibit multiple bioactive properties. In this study, we investigated the anti-platelet aggregation and antithrombotic activities of curdione with different methods both in vitro and in vivo. The purpose of the study was to explore an inhibitor of(More)
OBJECTIVES Chemoresistance is the main obstacle encountered in cancer treatment and is frequently associated with multidrug resistance (MDR). Astragaloside is a saponin which is widely used in traditional Chinese medicine. It has been reported that Astragaloside has antitumour effects on hepatocellular carcinoma Bel-7402 cells in vitro and in vivo. The(More)
Two polysaccharides (APS-I and APS-II) were isolated from the water extract of Radix Astragali and purified through ethanol precipitation, deproteination and by ion-exchange and gel-filtration chromatography. Their molecular weight was determined using high performance liquid chromatography and gel permeation chromatography (HPLC-GPC) and their(More)
The synergistic effect of combination treatment with COX-2 inhibitors and chemotherapy may be another promising therapy regimen in the future treatment of colorectal cancer. Curcumin, a major yellow pigment in turmeric which is used widely all over the world, inhibits the growth of human colon cancer cell line HT-29 significantly and specifically inhibits(More)
Inhibition of autophagy has been daily served as a promising anti-cancer treatment strategies. AstragalosideII (ASII), a main compound isolated from traditional Chinese medicine Radix Astragali, has been demonstrated to inhibit autophagy and reverse multidrug resistance in human hepatic cancer cells Bel-7402/5-FU. In this study, we inspected the function(More)
Rhizoma Curcumae (Ezhu) is a traditional Chinese medicine that has been used in removing blood stasis and alleviating pain for over a thousand years. Three species of Curcuma rhizomes are being used, which include Curcuma wenyujin, Curcuma phaeocaulis, and Curcuma kwangsiensis. In China, the production of Rhizoma Curcumae largely depends on agricultural(More)
Chemotherapy is the main treatment method of patients with advanced liver cancer. However, drug resistance is a serious problem in the treatment of hepatocellular carcinoma (HCC). Acid sensing ion channel 1a (ASIC1a) is a H+-gated cation channel; it mediates tumor cell migration and invasion, which suggests that it is involved in the development of(More)
It has been reported that icariin and icariside II, two flavonoid glycosides coming from herba epimedii, which have a closely structural relationship, show some pharmacological effects such as preventing osteoporosis, cancer and depression. The content of natural icariside II is very low in herba epimedii, but it is the main component in vivo after the(More)
Because of increased insensitivity or resistance to chemical treatment in tumor patients, specific apoptotic gene silence may provide a rational approach for the development of novel therapeutic strategies. This study was to investigate whether downregulation of Bcl-2 expression by small interfering RNA (siRNA) against the Bcl-2 gene would enhance the(More)
Acid-sensing ion channels (ASICs), a group of Na+-selective and Ca2+-permeant ligand-gated cation channels, can be transiently activated by extracellular acid. Among seven subunits of ASICs, acid-sensing ion channel 1a (ASIC1a), which is responsible for Ca2+ transportation, is elevated in response to inflammation, tumor, and ischemic injury in central(More)
