In vitro cultured shoot-tips of four grape (Vitis vinifera) cultivars and one kiwi (Actinidia deliciosa) cultivar were cryopreserved using the encapsulation-dehydration method. Genomic DNA of plantlets regenerated directly from cryopreserved shoot-tips was extracted and analyzed using the RAPD (Random Amplified Polymorphic DNA) technique. The RAPD profiles(More)
BACKGROUND Organ transplantation is a life-saving procedure for patients with organ failure. However, the side effects of long-term application of classic immunosuppressant remain major obstacles for successful transplantation. Therefore, new and safe immunosuppressive drugs against acute and chronic rejection are eagerly awaited. MATERIALS AND METHODS In(More)
Protein arginine methyltransferases (PRMTs) plays critical roles in cancer. PRMT5 has been implicated in several types of tumors. However, the role of PRMT5 in cancer development remains to be fully elucidated. Here, we provide evidence that PRMT5 is overexpressed in colorectal cancer (CRC) cells and patient-derived primary tumors, correlated with increased(More)
To elucidate the molecular mechanisms involved in the therapeutic effects of proanthocyanidins from grape seeds (GSPE), we explore whether GSPE regulates the inflammatory response of TNBS-induced colitis in rats at the levels of NF-κB signal transduction pathway. Rats were intragastrically administered of different doses of GSPE (100, 200 and 400 mg·kg-1)(More)
A previous study reported that ginsenoside-Rd reduced the production of tumor necrosis factor-α by inhibiting nuclear factor-κB in lipopolysaccharide-activated N9 microglia in vitro. The aim of the present study was to confirm the anti-inflammatory effects and mechanisms of ginsenoside-Rd in animal experiments involving acute inflammation. The results(More)
The aim of this study was to establish xenograft models of tumor in mice bladder and evaluate the antitumor efficacy of ampelopsin sodium (Amp-Na). A total of 2×10 human bladder carcinoma EJ cells and murine sarcoma 180 cells were instilled into the bladder of BALB/c nu/nu mice and Swiss mice after preconditioning to establish the tumor model. Mice bearing(More)
A new rhodamine-based chemosensor (L1) was synthesized, and it exhibits high sensitivity and selectivity for the copper cation over other commonly coexistent metal ions in aqueous solution. Upon the addition of Cu(2+), the spirolactam ring of L1 was opened and a 1 : 1 metal-ligand complex was formed. Fluorescent imaging of Cu(2+) in living cells is also(More)
IFNalpha2a-NGR is an antitumor agent of bacterial origin. The report presents the preclinical toxicity studies with IFNalpha2a-NGR in mice, rats and monkeys. The single-dose toxicity study showed no effect on general signs, body weight, food consumption, ophthalmology, hematology and clinical chemistry and necropsy analysis. In repeated-dose toxicity(More)
Protein arginine methyltransferase 5 (PRMT5), a type II PRMT, is highly expressed in some tumors, but its role in hepatocellular carcinoma (HCC) is still unknown. PRMT5 level in HCC specimens was determined by immunohistochemical staining and the association with clinicopathologic features was evaluated. PRMT5 was inhibited by AMI-1 (a small molecule(More)
Previously studies have shown that tumor-homing peptide NGR enhances the therapeutic efficacy of human interferon α2a (IFNα2a) against tumors. Here we investigated in vivo anti-tumor effect of recombinant human IFNα2a-NGR (rhIFNα2a-NGR) against human lung adenocarcinoma cell line SPC-A-1, A549 and murine Lewis lung carcinoma (LLC) subcutaneously xenografted(More)
