Objective To investigate potential mechanism of arsenic trioxide (As2O3) and/or adriamycin (ADM) induces apoptosis in hepatocellular carcinoma (HCC) cells. Methods Human hepatocellular (carcinoma) cells, HepG2, were treated with As2O3 combined with/without ADM in various concentrations for various time, and then the expression of survivin was detected by immunocytochemistry and RT-PCR (respectively). Results (1)Before the cells were interfered with drugs, survivin was highly expressed in HepG2 cells. (2)Expression of survivin was reduced in cells treated with various concentrations of As2O3 or ADM , and the reduction was dependent on durg concentration and time, these two factors were interrelated. (3)Expression of survivin was reduced more markedly in cells treated with ADM than in those treated with As2O3 and the reduction was additionally increased in cells treated with a combination of the two compounds. Conclusions (1)Either As2O3 or ADM can downregulate the expression of survivin in HepG2 cells in a concentration-or time-dependent manner; (2)At the same concentration, ADM is more effective than As2O3 on the downregulation of survivin expression in HepG2 cells, but the effect can be enhanced by combination of these two drugs. (3)As2O3 and ADM may induce apoptosis in HepG2 cells through the downregulation of survivin expression and thus exert their anti-cancer effect. Their combination may enhance their anti-tumor effect, so that in clinical use, the dosage of each durg may be reduced.

Objective To construct a new gene delivery system based on atelocollagen (ATE),and explore that modified aptamer (APT),and APT-ATE/miRNA (miRNA-15a and miRNA-16-1) were successfully synthesized to treat bone-metastatic prostatic cancers.Methods Flow cytometry (FCM) analysis was used to characterize APT-ATE complex.The diameter and zeta potential of complexes were measured by Zetasizer Nano-ZS9.The prostatic cancer (PCa) distribution experiments were used to explore its biological characteristics and targeting ability of PCa cells (PC3 and LNCaP).The inhibition of APT-ATE complex on LNCaP cell was determined with the cholecystokinin (CCK)-8 assay.Results FCM results demonstrated the successful synthesis of ATE-APT complex.The cellular uptake of vectors was concentration-dependent.The gene expression in vitro indicated that the modification of APT could increase the efficiency of gene expression and PCa targeting ability of ATE vectors to LNCaP [prostate specific membrane antigen (PSMA) over-expressing prostate cancer cells].The result of biodistribution showed that the bone uptake of APT-ATE was higher than ATE-APT.Conclusions APT-ATE/miRNA might be useful for preclinical and clinical studies on the treatment of bone-metastatic PCa.

Protein kinase D (PKD) is a novel family of serine/threonine kinases and diacylglycerol (DAG) receptors and has been documented in a variety of cellular processes. To get high purity catalytic domain of PKD1 (PKD1-cat) for crystallography study, the GST-tagged PKD1-cat gene was cloned into a baculovirus transfer vector pFastBac1 (donor plasmid). When the recombinant plasmid was transformed into DH10Bac competent Escherichia coli, which contains a baculovirus shuttle vector (bacmid), transposition occurs to generate a recombinant bacmid containing the gene of interest (GST-PKD1-cat). The recombinant bacmid DNA was transfected into Spodoptera frugiperda Sf9 insect cells to generate recombinant baculovirus, which was then amplified through multiple rounds of infection in Sf9 cells. After that, Trichoplusia ni insect cells in suspension culture were infected with baculoviral stock at a multiplicity of infection (MOI) of 5 PFU/cell. SDS-PAGE and Western blotting analysis confirmed the detection of a 68 kDa protein by the glutathione S-transferase (GST) monoclonal antibody. The recombination protein was purified by Glutathione sepharose affinity chromatography and cleaved by PreScission Protease to remove GST tag, and a highly pure 42 kDa protein which was consistent with the molecular weight of the expected PKD1-cat protein was detected on SDS-PAGE. The activity of purified PKD1-cat protein was determined by in vitro PKD kinase assay. Our data showed that the kinase activity increased with the concentration of purified PKD1-cat protein. These results showed that the truncated recombinant PKD1-cat protein was highly active and pure, and could potentially be used for solving 3D structure of this protein by Nuclear Magnetic Resonance (NMR) or crystallography.
