Am. J. Physiol. Renal Physiol. 284, F829–F839. Renal tubular epithelial cell apoptosis is associated with caspase cleavage of the NHE1 Na+/H+ exchanger. 2003

Wu, K.L., Khan, S., Lakhe-Reddy, S., Wang, L., Jarad, G., Miller, R.T., Konieczkowski, M., Brown, A.M., Sedor, J.R. and Schelling, J.R.

Notes: This paper describes amplification of rat NHE1 cDNA using primers incorporating the Xho I and Xba I restriction endonuclease sites, Kozak consensus, ATG start site, and a stop codon. The resultant 1.1 kb NHE1 encoding-PCR product was digested with Xba I and Xho I and cloned into the pTNT™ Vector.  This construct was used as a template in a TNT® T7 Quick Coupled Transcription/Translation reaction to generate substrates for an in vitro caspase-3 cleavage assay. Proteolytically cleaved fragments of NHE1 were run on a polyacrylamide gel and visualized by autoradiography. (3063)

J. Biol. Chem. 277(21), 18411-20. Kaurane diterpene, kamebakaurin, inhibits NF-kappa B by directly targeting the DNA-binding activity of p50 and blocks the expression of antiapoptotic NF-kappa B target genes. 2002

Lee, J.H., Koo, T.H., Hwang, B.Y. and Lee, J.J.

Notes: To investigate the effect of the compound kamebakaurin (KA) on NF-κB, an NF-κB-responsive firefly luciferase vector was transfected into HeLa, Jurkat and THP-1 cells. The Luciferase Assay System was used to assay the level of NF-κB induction after treatment of cells with various concentrations of KA. To determine if KA influenced the DNA-binding activity of NF-κB, nuclear extracts of HeLa, Jurkat and THP-1 cells were prepared after preincubation with KA and stimulation of NF-κB activity. Control nuclear extracts were prepared from unstimulated p50- or RelA-overexpressed MCF-7 cells. In addition, the wildtype and DNA-binding mutant RelA and p50 (NF-κB) His-tagged proteins were translated using the TNT® Quick Coupled Transcription/Translation System and subsequently purified. Using the Gel Shift Assay System, the NF-κB and AP1 oligos were tested for electromobility shifts with the prepared nuclear extracts or with purified wildtype and mutant proteins. Supershift studies using anti-p50 or anti-RelA antibodies were also performed. (3113)

Zhang, M. and Chiang, J.Y.

Notes: To study the transcriptional control of human CYP8B1 by bile acids, the -514/+300 region of the gene was cloned into the pGL3-Basic Vector and subsequently mutagenized at both the 5´ and 3´ends of the CYP8B1 fragment.  The various reporter constructs were then transfected into HepG2 cells and the activity assessed using the Luciferase Assay System. Luminescence was determined using a Berthold Lumat LB 9501 luminometer. The Gal4/Id and VP16/MyoD provided in the CheckMate™ Mammalian Two-Hybrid System were used as positive controls for the in a two-hybrid assay that examined the interaction of SHP and HNF4alpha, genes that regulate CYP8B1.  The TNT® Quick Coupled Transcription/Translation System was used to synthesize various receptor proteins cloned in expression plasmids.

Plant Cell 12(2), 279-290. The Arabidopsis NPR1/NIM1 protein enhances the DNA binding activity of a subgroup of the TGA family of bZIP transcription factors. 2000

Despres, C., DeLong, C., Glaze, S., Liu, E. and Fobert, P.R.

Notes: The Arabidopsis NPR1 protein is part of a systemic and inducible plant defense mechanism and may be the plant homolog to IκBα, the NF-κB regulator. In a yeast two-hybrid screen, it was found that NPR1 interacts with several TGA factors. To verify these interactions, NPR1 was expressed and biotinylated in E. coli XL1-Blue using the Pinpoint™ Xa-1 Vector. The biotinylated protein was affinity-purified from a sonicated culture using TetraLink™ Tetrameric Avidin Resin. The captured NPR1 was assayed for interaction with TGAs produced and radiolabled with 35S-methionine. It was found that NPR-1 binds to TGA2 strongly and to TGA4 weakly. The TGA4 interaction was negative in the yeast two-hybrid system. A C150Y transition mutant of NPR1 did not bind TGA2. (2707)
