Nanomaterials based on chitosan have emerged as promising carriers of therapeutic agents for drug delivery due to good biocompatibility, biodegradability, and low toxicity. Chitosan originated nanocarriers have been prepared by mini-emulsion, chemical or ionic gelation, coacervation/precipitation, and spray-drying methods. As alternatives to these(More)
Polymeric micelles (PM) system, as an efficient drug carrier, has received growing scientific attention in recent years owing to its solubilization, selective targeting, P-glycoprotein inhibition and altered drug internalization route and subcellular localization properties. Seven PM formulations of anti-tumor drugs being evaluated in clinical trials are(More)
ETHNOPHARMACOLOGICAL RELEVANCE Hepatocellular carcinoma (HCC) as the major histological subtype of primary liver cancer remains one of the most common malignancies worldwide. Due to the complicated molecular pathogenesis of HCC, the option for effective systemic treatment is quite limited. There exists a critical need to explore and evaluate possible(More)
ETHNOPHARMACOLOGICAL RELEVANCE Following the known principle of "fighting fire with fire", poisonous Chinese herbal medicine (PCHM) has been historically used in cancer therapies by skilled Chinese practitioners for thousands of years. In fact, most of the marketed natural anti-cancer compounds (e.g., camptothecin derivatives, vinca alkaloids, etc.) are(More)
Berberine hydrochloride (BH) is an isoquinolin alkaloid with promising anticancer efficacies. Nevertheless, further development and application of this compound had been hampered by its poor aqueous solubility, low gastrointestinal absorption, and rapid metabolism in the body. In this study, a solid lipid nanoparticle (SLN)-based system was developed for(More)
Store-operated Ca(2+) entry (SOCE) has recently been proposed to contribute to Ca(2+) influx in vascular smooth muscle cells (VSMCs). Adenosine is known for its protective role against hypoxia and ischemia by increasing nutrient and oxygen supply through vasodilation. This study was designed to examine the hypothesis that SOCE have a functional role in(More)
OBJECTIVE Drug resistance remains a major challenge for effective breast cancer chemotherapy. Resveratrol (Res) is a promising candidate for overcoming cancer chemoresistance, but it has low bioavailability due to poor absorption, and ready metabolism limits its application. This study aims to develop a Res-loaded mixed micelle system to be effective on(More)
Penthorum chinense Pursh (P. chinense), a traditional Chinese medicine used by the Chinese Miao minority, has been used to treat liver diseases for a long time. However, the mechanism behind the liver protective effects of P. chinense remains unclear so far. The aim of the present study was to investigate the hepatoprotective effect of P. chinense and its(More)
The objective of the present study was to prepare and characterize emodin (EMO)-loaded solid lipid nanoparticles (E-SLNs) and evaluate their antitumor activity in vitro. EMO and pharmaceutical lipid material were used to prepare E-SLNs by high pressure homogenization (HPH). Poloxamer 188 and Tween 80 were used as surfactants. The physicochemical properties(More)
The development of resistance to chemotherapeutic agents remains a major challenge to breast cancer chemotherapy. Overexpression of drug efflux transporters like P-glycoprotein (P-gp) and resistance to apoptosis are the two key factors that confer cancer drug resistance. Gambogic acid (GA), a major component of Gamboge resin, has potent anticancer effects(More)
