It has been shown that Caspy2, a zebrafish active caspase, can efficiently suppress the growth of malignant tumor. The present study was designed to test whether combined gene therapy with IP-10, a potent antitumor chemokine, and Caspy2 would improve therapy efficacy. Recombinant plasmid expressing both Caspy2 and IP-10 genes was mixed with(More)
The Delta-12 oleate desaturase gene (FAD2-1), which converts oleic acid into linoleic acid, is the key enzyme determining the fatty acid composition of seed oil. In this study, we inhibited the expression of endogenous Delta-12 oleate desaturase GmFad2-1b gene by using antisense RNA in soybean Williams 82. By employing the soybean cotyledonary-node method,(More)
Polo-like kinase 1 (PLK1) showing a high expression in various kinds of tumors is considered a candidate target for cancer therapy. The aim of our study was to explore the effects of silencing PLK1 gene on human colorectal carcinoma cell line HCT-116 in vitro and in vivo. In vitro, the plasmids generating short hairpin RNA (shRNA)-targeting PLK1 were(More)
OBJECTIVE To trace the pathological changes of the cultured autologous chondrocytes mass after implanted in cartilage defects and investigate the pathophysiological mechanisms of the antologous chondrocytes mass transplantation in the repair of cartilage defects. METHODS Twenty-four New Zealand white rabbits of 4 to 6 month-old and weighing more than 3.0(More)
BACKGROUND Recombinant human endostatin (rh-endostatin, Endostar) has been proved to be an inhibitor of angiogenesis. Docetaxel has been also considered as a common chemotherapeutic agent with inhibition of angiogenesis of malignancies. However, their function has been seldom compared and a best synergism protocol is not determined. This study aimed to(More)
BACKGROUND Peripheral nerve regeneration across large gaps is clinically challenging. Scaffold design plays a pivotal role in nerve tissue engineering. Recently, nanofibrous scaffolds have proven a suitable environment for cell attachment and proliferation due to similarities of their physical properties to natural extracellular matrix. Poly(propylene(More)
OBJECTIVE To develop a novel cartilage ECM-derived porous scaffold (CEDPS) and investigate the attachment, proliferation and distribution of bone marrow mesenchymal stem cells (BMSCs) cultured in vitro within the scaffolds. METHODS Cartilage microfilaments were prepared after pulverization and gradient centrifugation and prepared into suspension after(More)
Osteoporosis is associated with delayed and/or reduced fracture healing. As cervus and cucumis are the traditional Chinese treatments for rheumatoid arthritis, we investigated the effect of supplementation of these peptides (CCP) on bone fracture healing in ovariectomized (OVX) osteoporotic rats in vitro and in vivo. CCP enhanced osteoblast proliferation(More)
Incidents associated with methanol intoxication resulting from the consumption of fake wine occur not infrequently worldwide. Certain individuals are made blind due to methanol poisoning. The present study aimed to investigate the effects of sodium formate exposure on photoreceptor cells (661W cells). The 661W cells were exposed to sodium formate for 6‑24 h(More)
OBJECTIVE To explore the feasibility of repairing the articular cartilage with allo-articular chondrocytes embedded in alginate gel. METHODS Allo-articular chondrocytes were isolated from three adult New zealand rabbits. The cells were cultured in DMEM/F-12 supplemented with 20% fetal bovine serum (FBS). Chondrocytes of 2nd - 3rd passage were harvested(More)
