Rapeseed (Brassica napus L.) is the third most important oil crop in global productions. One of the major limiting factors for oilseed rape production is lepidopteran pests of the Brassicaceae family. Transgenic plants expressing Bacillus thuringiensis (Bt) genes are powerful tools in the integrated pest management of crop plants. In the present study, we used a synthetic Bt insecticidal crysta...

The bacterial backbone (BB) sequences contained within a canonical plasmid DNA dampen exogenous transgene expression by tenfold to 1,000-fold over a period of a few weeks following transfection into quiescent tissues such as the liver. Minicircle DNA vectors devoid of bacterial plasmid backbone sequences overcome transgene silencing providing persistent transgene expression. Because, we recentl...

Telomerase-specific replication-competent adenoviruses (Ads), i.e., TRADs, which possess an E1 gene expression cassette driven by the human telomerase reverse transcriptase promoter, are promising agents for cancer treatment. However, even though oncolytic Ads, including TRAD, are intratumorally administered, they are disseminated from the tumor to systemic circulation, causing concern about on...

Objective(s): Multidrug resistance (MDR) is a major obstacle in the successful chemotherapy of ovarian cancer. Inhibition of P-glycoprotein (P-gp), a member of ATP-binding cassette (ABC) transporters, is a well-known strategy to overcome MDR in cancer. The aim of this study was to investigate the efficiency and ability of CRISPR/Cas9 genome editing technology to knockdown ABCB1 gene expression ...

A versatile green fluorescent protein (GFP) expression cassette containing the replication origins of the monopartite begomovirus Tomato yellow leaf curl Sardinia virus (TYLCSV) is described. Transgenic Nicotiana benthamiana plants containing one copy of the cassette stably integrated into their genome were superinfected with TYLCSV, which mobilized and replicated the cassette as an episomal re...

In vitro assays identified the Golgi peripheral protein GRASP65 as a Golgi stacking factor that links adjacent Golgi cisternae by forming mitotically regulated trans-oligomers. These conclusions, however, require further confirmation in the cell. In this study, we showed that the first 112 amino acids at the N-terminus (including the first PDZ domain, PDZ1) of the protein are sufficient for oli...

A chloride-inducible promoter previously isolated from the chromosome of Lactococcus lactis (J. W. Sanders, G. Venema, J. Kok, and K. Leenhouts, Mol. Gen. Genet., in press) was exploited for the inducible expression of homologous and heterologous genes. An expression cassette consisting of the positive-regulator gene gadR, the chloride-inducible promoter Pgad, and the translation initiation sig...

The adenosine triphosphate-binding cassette transporter-homologous gene ATP11A belongs to an extended family of adenosine triphosphate-binding cassette transporters. We analysed the ATP11A gene in 7 colorectal cancer cell lines and 95 paired cases of colorectal cancer and non-cancerous regions to demonstrate the importance of ATP11A expression in colorectal cancer prognosis. ATP11A was expresse...
