Tupistra chinensis is a widely used medicinal plant in Hubei Province, China. In our study, we investigated the effect of polysaccharides component from Tupistra chinensis on mice in vivo. The mice H22 hepatocarcinoma animal model was established firstly. Then, the mice were fed with different doses of polysaccharides derived from Tupistra chinensis (one time each day). The neoplasm growth cond...
Tumor vascular normalization involved in immune response is beneficial to the chemotherapy of tumors. Recombinant human endostatin (Endostar), an angiogenesis inhibitor, has been demonstrated to be effective in hepatocellular cancer (HCC). However, its vascular normalization in HCC and the role of the immune response in angiogenesis were unclear. In the present study, effects of Endostar on tum...
BACKGROUND The B7-H1/PD-1 pathway has been demonstrated to be involved in tumor evasion. In a previous study, we constructed a eukaryotic expression plasmid (pPD-1A), which expresses soluble PD-1 (sPD-1). In this study, the question of whether or not the blockade of B7-H1 with sPD-1 in vivo and vitro can improve antitumor immunity was investigated. MATERIALS AND METHODS The proliferation of l...
Patrinia heterophylla Bunge, Caprifoliaceae, is a traditional Chinese medicine that has been used for cancer therapy. In our study, a panel of human cancer cells was treated with extract of Patrinia heterophylla Bunge. (PHEB), MTT study showed that PC-3 Human prostate adenocarcinoma was the most responsive (IC50 9.21±0.32 μg/mL) one to cell growth inhibition, the further study also demonstrated...
Paclitaxel (Ptx), one of the most widely used anticancer agents, has demonstrated extraordinary activities against a variety of solid tumors. However, the therapeutic response of Ptx is often associated with severe side effects caused by its nonspecific cytotoxic effects and special solvents (Cremophor EL(®)). The current study reports the stable controlled release of Ptx/tetrandrine (Tet)-colo...
A total of ~38.6 million mortalities occur due to liver cancer annually, worldwide. Although a variety of therapeutic methods are available, the efficacy of treatment at present is extremely limited due to an increased risk of malignancy and inherently poor prognosis of liver cancer. Gene therapy is considered a promising option, and has shown notable potential for the comprehensive therapy of ...
The objective of the present study was to evaluate the antioxidant activity, antitumor effect, and antiaging property of proanthocyanidins from Kunlun Chrysanthemum flowers (PKCF) grown in Xinjiang. In vitro antioxidant experiments results showed that the total antioxidant activity and the scavenging capacity of hydroxyl radicals ((•)OH) and 1,1-diphenyl-2-picrylhydrazyl (DPPH(•)) radicals incr...
Copper transporter 1 (CTR1) is a transmembrane protein that imports copper(i) into yeast and mammalian cells. Surprisingly, the protein also mediates the uptake of platinum anticancer drugs, e.g. cisplatin and carboplatin. To study the effects of several metal-binding residues/motifs of hCTR1 on the transport of both Cu(+) and cisplatin, we have constructed Hela cells that stably express a seri...
