OBJECTIVE To develop a novel protein-anchor technology to immobilize human interleukin-2 on tumor cells to induce antitumor immunity. METHODS Interleukin-2 surface-modified MB49 cells were prepared as a vaccine. Subcutaneous and pulmonary metastatic mouse models of MB49 bladder cancer were used to evaluate the antitumor efficiency of the vaccine.(More)
Chemotherapy combined with a tumor vaccine is an attractive approach in cancer therapy. This study was designed to investigate the optimal schedule and mechanisms of action of a novel GM-CSF (granulocyte–macrophage colony-stimulating factor) surface-modified tumor-cell vaccine in combination with paclitaxel in the treatment of mouse RM-1 prostate cancer.(More)
In situ gene therapy with granulocyte-macrophage colony-stimulating factor (GM-CSF) was demonstrated to successfully inhibit tumour cell growth in a mouse orthotopic bladder cancer model, but suffered from several disadvantages, such as limited efficiency for gene delivery, low expression efficiency of the transgene and the safety concern resulting from(More)
Cdc6, an essential initiation protein for DNA replication, also participates in the ATR checkpoint pathway and plays a vital role in tumorigenesis. It is involved in the androgen receptor (AR) signal transduction and promotes the malignant progression of prostate cancer (PCa). In this study, we report that norcantharidin (NCTD) induces the degradation of(More)
PURPOSE Immunotherapy is considered effective for muscle invasive bladder cancer mini metastasis. We developed what is to our knowledge a novel technology by which streptavidin tagged mouse GM-CSF was displayed on the surface of biotinylated bladder cancer cells to induce antitumor immunity. MATERIALS AND METHODS Mouse subcutaneous and lung metastasis(More)
BACKGROUND Intravesical administration is an important treatment against superficial bladder cancer and CD40L is essential for the protective anti-tumor immunity. In situ gene therapy with CD40L was demonstrated to successfully inhibit tumor cell growth in the orthotopic mouse model of bladder cancer. In the present study, we prepared streptavidin(More)
Norcantharidin (NCTD) is currently used for anticancer therapy but the exact mechanism of action remains unknown. Pre-replicative complexes (pre-RCs) are essential for cell DNA replication and highly related to malignant proliferation. Here, we examined the inhibitory effect of NCTD on pre-RC components in HepG2 cells. We showed that NCTD induced(More)
As a type of renewable and clean energy, solar energy is highly emphasized for its advantages in avoiding environmental pollution and realizing the sustainable development of natural resources. Rooftops of buildings are feasible options to utilize solar energy in urban area. This paper presents an object-based method to locate the appropriate sites for(More)
Protein phosphatase 1, regulatory subunit 13 like PPP1R13L, also coined iASPP, was found high expression in prostate cancer tissues and cell lines. In previous research, in vitro and in vivo RNAi mediated by artificial lentiviral shRNAs which proved that suppression of iASPP decrease the proliferation of cancer cells. Endogenous interference RNAs, microRNAs(More)
Schwannomas are mesenchymal neoplasms with a low malignant potential, which arise from Schwann cells. The tumors can occur in most parts of the body; however, the head, neck and flexor surfaces of the extremities are the most common locations. Schwannomas occurring in the hepatoduodenal ligament are extremely rare. To the best of our knowledge, only two(More)
