Mol. Cancer Res. 1, 475-84. Gene expression profiling in prostate cancer cells with Akt activation reveals Fra-1 as an Akt-inducible gene. 2003

Tiwari, G., Sakaue, H., Pollack, J.R., and Roth, R.A.

Notes: These authors analyzed gene expression profiles in the prostate cancer cell line PC3 upon induction of Akt activity to try to identify genes regulated by Akt that participate in the transformation of cells. They identified one mRNA of interest (Fra-1) and cloned its 5' regulatory region into a pGL3-Basic firefly luciferase reporter construct. This construct was used to transiently transfect MCF7 human breast cancer cells along with an Akt plasmid construct and a control vector expressing Renilla luciferase. The firefly construct was induced 4- to 5-fold by co-transfection with Akt3. Transfection conditions were as follows: MCF-7 cells were grown to 70% confluence in six-well plates, then incubated for 15 min with a mixture of 5ng of the control Renilla plasmid, 0.5μg of the Akt-expressing plasmid, and 0.5μg of pFra-luc construct and Fugene® 6 reagent at a 3:1 transfection reagent:DNA ratio. After 48 hours, luciferase activity was assessed using the Dual-Luciferase® Reporter Assay System.

J. Biol. Chem. 278, 7445–7452. Microtubule disruption utilizes an NFkappa B-dependent pathway to stabilize HIF-1alpha protein. 2003

Jung, Y.J., Isaacs, J.S., Lee, S., Trepel, J. and Neckers, L.

Notes: In this paper, the role of microtubules on regulation of hypoxia-inducible factor (HIF) 1-α was explored. A549 human lung cancer cells were transiently transfected with 5µg of NFκB super-repressor plasmid or 3µg of either HA-tagged wild type or mutated HIF-1α construct using FuGENE® 6 Transfection Reagent in 6cm dishes. Twenty-four hours post-transfection, the cells were treated with vinblastine or colchicine before lysing the cells and analyzing the lysate by Western blotting using anti-HIF-1α or anti-HA antibodies (Figures 3 and 6 in article). A549, hepa1c1c7 and hepa1c4 cells were transiently cotransfected with 0.4µg of an iNOS luciferase construct or an NFκB-dependent luciferase vector and 4ng of a CMV Renilla luciferase plasmid in six-well plates. After six hours, the cells were treated with vinblastine, colchicine, nocodazole and paclitaxel and incubated for an additional 6–10 hours. The luciferase activity was then assessed using the Dual-Luciferase® Reporter Assay System (Figures 2 and 4). (4293)

J. Gene Med. 5(8), 723-732. Development of a dual-luciferase fusion gene as a sensitive marker for site-directed DNA repair strategies 2003

Bennett, M. and Schaack, J.

Notes: These authors created a construct encoding a Renilla and firefly luciferase fusion protein to examine the efficiency of site-specific DNA repair. The Renilla gene was taken from the pRL-null Vector and the firefly luciferase gene originated from the pSP-luc+NF Fusion Vector. The fusion construct was created by ligating the C-terminus of the Renilla luciferase gene to the N-terminus of the firefly gene.  The fused proteins were expressed at a constant ratio when transfected into mammalian cells.  Firefly luciferase expression was eliminated by deleting a T at position 213 creating an ochre translational stop codon and placing the downstream sequence out of frame. The mutant protein was then tested for repair using two methods: small fragment homologous replacement and oligonucleotide-mediated repair. The Renilla:firefly expression ratio was tested in several human, murine and simian cell lines and assayed 48 hours post-transfection using the Dual-Luciferase® Reporter Assay System.  In addition, the repaired plasmids were recovered to verify the sequence correction.

J. Biol. Chem. 278(34), 31895-31901. Down-regulation of hypoxia-inducible factor-2 in PC12 cells by nerve growth factor stimulation. 2003

Naranjo-Suárez, S., Carmen Castellanos, M., Alvarez-Tejado, M., Vara,A., Landázuri, M.O. and del Peso, L.

Notes: In this paper, the authors describe use of ImProm-II™ Reverse Transcriptase to transcribe cDNAs for Quantitative RT-PCR. Reverse transcription (RT) reactions were performed with 1μg total RNA from treated rat PC12 cells. Light Cycler reactions were setup with 1-3μl cDNA from the RT reactions. The researchers incubated cells with EGF and bFGF and analyzed HIF-2α mRNA levels. For these experiments, PC12 cells were incubated with 30ng/ml EGF or 50μM bFGF for 8 hours. Erk1&2 phosphorylation was examined by Western blot using the Anti-ACTIVE® MAPK pAb. Western results were visualized by chemiluminesent detection and analyzed with a digital luminescent image analyzer. The Dual-Luciferase® Reporter Assay System was used to analyze PC12 cell-expressed luciferase from pEpoEm1-luc and pEpoE-luc promoter constructs that were normalized with the pRL-TK vector. Cells were harvested 17-18 hours post transfection and treatment. (2725)

Plant J. 35(2), 273-283. Gene trapping of the Arabidopsis genome with a firefly luciferase reporter. 2003

Yamamoto, Y.Y., Tsuhara, Y., Gohda, K., Suzuki, K. and Matsui, M.

Notes: These researchers used luciferase-containing T-DNA insertions in Arabidopsis thaliana for gene trapping. Luciferase was chosen because its transient expression allowed temporal expression studies. Several insertion vectors were constructed and found to have different insertion frequencies. Vectors containing the luc+ gene had substantially higher insertion rates than native luciferase vectors. Luciferase activity was measured in vivo with a CCD camera or, for longer term studies, with an automated scintillation counter sampling every 15-25 minutes over one week. The application of IRES sites in gene trapping experiments was also investigated using firefly and Renilla luciferases. The Dual-Luciferase® Reporter Assay System was used to monitor luciferase activity in vitro. Finally, to sequence the T-DNA insertion sites, genomic DNA was isolated from T2 seedlings using the Wizard® Magnetic 96 DNA Plant System and was subsequently amplified and sequenced. (2787)

Cancer Res. 63(10), 2658-64. Transactivation of vimentin by beta-catenin in human breast cancer cells. 2003

Gilles C., Polette M., Mestdagt M., Nawrocki-Raby B., Ruggeri P., Birembaut P. and Foidart J.M.

Notes: The authors explored the role of beta-catenin and T-cell factor 4 to transactivate vimentin, a protein involved in gain of mesenchymal characteristics and loss of epithelial characteristics as a precursor to metastasis. The vimentin promoter was cloned into the pGL3-Basic Vector. The beta-catenin/TCF binding sites upstream of a minimal c-fos promoter drove firefly luciferase expression in plasmids called TOP-FLASH (wild-type binding sites) and FOP-FLASH (mutant binding sites).  To examine beta-catenin/TCF-4 induction, several human mammary epithelial cell lines were transfected with a mixture of 0.15µg of various firefly reporter constructs (wild type vimentin promoter, mutant vimentin promoter, TOP-FLASH,or FOP-FLASH), 0.15 µg of the beta-catenin expression vector (or the corresponding empty vector), 0.15 µg of the TCF-4 expression vector and 0.8 ng of the Renilla luciferase vector, phRG-TK.  Twenty-four hours after transfection, the cells were lysed and assayed using the Dual-Luciferase® Reporter Assay System.

Ramsay, P.L., Luo, Z., Magdaleno, S.M., Whitbourne, S.K., Cao, X., Park, M.S., Welty, S.E., Yu-Lee, L.Y. and DeMayo, F.J.

Notes: To investigate how interferon gamma stimulates expression of the murine Clara cell secretory protein (CCSP) gene, the 280bp CCSP promoter region was radiolabeled and incubated with nuclear extract from mouse transformed Clara cells (mtCC). Transcription factor binding sites were identified using the Core Footprinting System. A 30bp section of the CCSP promoter containing three transcription factor consensus sites was synthesized with 0, 1 or 2 mutated binding sites and tested in the presence of mtCC nuclear extract. Oligos and nuclear extract were allowed to form complexes with or without interferon gamma in Gel Shift Binding Buffer. A 166bp section of the CCSP promoter was also cloned into the pGL3-Basic Vector and co-transfected with the pRL-TK Vector into mtCC. The cells were subjected to interferon gamma treatment and the cell lysates assayed using the Dual-Luciferase® Reporter Assay System.
