Plant Physiol. 146, 1469–81. Deregulation of maize C4 photosynthetic development in a mesophyll cell-defective mutant. 2008

Covshoff, S., Majeran, W., Liu, P., Kolkman, J.M., van Wijk, K.J. and Brutnell, T.P.

Notes: The authors identified the maize homolog of hcf136 (Zmhcf136), a gene involved in photosynthesis, and used an RNA blot to determine if ZmHcf136 transcripts accumulate preferentially in mesophyll cells. DNA probes for Zmhcf136 and several cell-specific markers were generated by PCR using GoTaq® Green Master Mix, gel purified and radiolabeled prior to use in the RNA blots. To examine differences in protein accumulation and localization in wildtype and hcf136 mutants, proteins from subcellular fractions were subjected to two-dimensional gel electrophoresis, and spots of interest were excised, digested with Sequencing Grade Modified Trypsin, then analyzed by electrospray ionization-tandem mass spectrometry.

J. Clin. Oncol. 26, 5783-8. Feasibility of screening for Lynch Syndrome among patients with colorectal cancer. 2008

Hampel H, Frankel WL, Martin E, Arnold M, Khanduja K, Kuebler P, Clendenning M, Sotamaa K, Prior T, Westman JA, Panescu J, Fix D, Lockman J, LaJeunesse J, Comeras I, de la Chapelle A.

Notes: Lynch syndrome (LS) is due to mutations in at least four DNA mismatch repair (MMR) genes. There are two tumor characteristics that can be screened for in an attempt to identify patients with CRC who are most likely to have LS. These characteristics are microsatellite instability (MSI) and loss of one or two of the MMR proteins in the tumor compared to normal tissue. MSI testing and IHC for the four mismatch repair proteins was performed on 500 tumors from unselected patients with CRC. If either MSI or IHC was abnormal, complete mutation analysis for the mismatch repair genes was performed. GoTaq Master Mix (Cat.# M7122, Cat.# M7132) (4111)

J. Biol. Chem. 283, 23514–23. Snail regulates cell-matrix adhesion by regulation of the expression of integrins and basement membrane proteins. 2008

Haraguchi, M., Okubo, T., Miyashita, Y., Miyamoto, Y., Hayashi, M., Crotti, T.N., McHugh, K.P. and Ozawa, M.

Notes: Snail is a transcriptional repressor of E-cadherin that enhances both cell attachment and cell detachment in Madin Darby canine kidney (MDCK) and A4231 cells. To investigate this effect, the authors used Western blot analysis and RT-PCR to monitor protein and mRNA levels of the major adhesive proteins expressed in epithelial cells: laminin, heparin sulfate proteoglycan and collagens. For RT-PCR, total RNA was isolated from transiently transfected snail-expressing MDCK and A431 cells and untransfected cells, then reverse transcribed. The resulting cDNA was amplified by PCR using GoTaq® DNA Polymerase; glyceraldehyde-3-phosphate dehydrogenase was amplified as an internal control. The ability of Snail to regulate the integrin αV promoter was also examined by cloning the promoter and several promoter deletions upstream of a firefly luciferase reporter gene in the pGL3-Basic Vector. Each of these constructs (1µg) and 20ng of pRL-CMV Vector were transfected into MDCK and MDCK/snail cells, and luminescence was measured using the Dual Luciferase Assay System. (3882)

Am. J. Pathol. 171, 19–31. A sertoli cell-specific knockout of connexin43 prevents initiation of spermatogenesis. 2007

Brehm, R., Zeiler, M., Rüttinger, C., Herde, K., Kibschull, M., Winterhager, E., Willecke, K., Guillou, F., Lécureuil, C., Steger, K., Konrad, L., Biermann, K., Failing, K. and Bergmann, M.

Notes: To study the role of connexin42 (cx43) in testis development, the authors generated a conditional cx43 knockout mouse, which lacked the cx43 gene in Sertoli cells. To confirm that the cx43 gene was deleted in these mice, PCR was performed using primers specific to cx43, 1X Colorless GoTaq® Flexi Reaction Buffer, 2mM MgCl2, dNTPs and 0.15µl of GoTaq® DNA Polymerase. Tissue-specific deletion of cx43 was confirmed by amplifying RNA isolated from mouse testis, heart and tail was also confirmed using the same PCR components. (3713)

Proc. Natl. Acad. Sci. USA 104, 10637–10642. Commensal and pathogenic Escherichia coli use a common pilus adherence factor for epithelial cell colonization. 2007

Rendón, M.A., Saldaña, Z., Erdem, A.L., Monteiro-Neto, V., Vázquez, A., Kaper, J.B., Puente, J.L. and Girón, J.A.

Notes: The authors identified an adherence factor of enterohemorrhagic E. coli that is involved in colonization of cultured epithelial cells. This factor, named E. coli common pilus (ECP), is encoded by the ecpA gene, which is present 96% of E. coli strains tested, as determined by PCR. The remaining 4% of the strains were found to be deficient in the ECP operon, as determined by multiplex PCR amplification of ecpR, ecpA, epcB and ecpC sequences. PCR were performed using GoTaq® Green Master Mix. An ecpA deletion mutant exhibited impaired adherence compared to the wildtype E. coli strain. Complementation of the mutant strain with the plasmid pMR13, the pGEM®-T Vector containing the ecpA gene, restored the strain's ability to adhere to epithelial cells. (3719)

J. Biol. Chem. 282, 21818–21828. Degradation of hsp70 and other mRNAs in Drosophila via the 5´ 3´ pathway and its regulation by heat shock. 2007

Bönisch, C., Temme, C., Moritz, B. and Wahle, E.

Notes: The authors studied hsp70 mRNA degradation in Drosophila Schneider cells. mRNA deadenylation and decay were monitored by Northern blot. Two of the Northern blot probes used to visualize the mRNA decay products were synthesized by transcription of linearized plasmids using T7 RNA Polymerase and [α-32P] UTP. A population of deadenylated mRNA was created by hybridizing mRNA with oligo(dT) and treating with RNase H. CCR4•NOT was identified as the main deadenylase involved in mRNA decay, and the PAN2:PAN3 deadenylase was a minor contributor. RNA interference was used to knock down expression of PAN2 and CAF1, a subunit of CCR4•NOT, to assess the effect on mRNA decay. Reduced expression levels of PAN2 and CAF1 were confirmed by semi-quantitative RT-PCR and Western blotting, respectively. RT-PCR was performed using 1.5µg total RNA and 150 units of MMLV Reverse Transcriptase in a 25µl reaction. One microliter of the RT reaction was used as a template in an 80µl PCR using 0.5 units of GoTaq® DNA Polymerase, 1.5mM MgCl2 and 1X Green GoTaq® Flexi Reaction Buffer. (3707)

J. Biol. Chem. 282, 29847–29854. Differential regulation of vitamin D receptor (VDR) by the p53 family: p73-dependent induction of VDR upon DNA damage. 2007

Kommagani, R., Payal, V. and Kadakia, M.P.

Notes: The authors examined transcriptional regulation of the vitamin D receptor (VDR) by p53 and p63, a member of the p53 family, under stressed and unstressed conditions. Reporter constructs with the full-length and minimal VDR promoters controlling expression of firefly luciferase were cotransfected with p53 or p63 expression constructs, and transcriptional activation of the VDR promoter was monitored using the Dual-Luciferase® Reporter 100 Assay System. Results were normalized to Renilla luciferase activity. Interaction between p73, another member of the p53 family, and the VDR promoter was examined using chromatin immunoprecipitation. The imunnopreciptated chromatin was reverse crosslinked, DNA was eluted and VDR and p21 sequences were detected by PCR using GoTaq® Green Master Mix. (3715)

J. Clin. Invest. 117, 3042–3048. HLA class I polymorphisms are associated with development of infectious mononucleosis upon primary EBV infection. 2007

McAulay, K.A., Higgins, C.D., Macsween, K.F., Lake, A., Jarrett, R.F., Robertson, F.L., Williams, H. and Crawford, D.H.

Notes: The authors examined whether genetic differences at the HLA class I locus affect development of Epstein Barr Virus-associated diseases. Peripheral blood mononuclear cells were isolated from asymptomatic EBV-seropositive and seronegative individuals and patients with acute infectious mononucleosis. DNA was isolated, and genotypes at two HLA class I loci and one HLA class III locus, as a control, were determined by PCR. The 10µl PCRs contained 25ng of DNA, 1X GoTaq® Flexi Reaction Buffer, 2.5mM MgCl2, 200µM dNTP, 0.5 units of GoTaq® Flexi DNA Polymerase and 25µM of forward and reverse primer, one of which was labeled with 6-FAM fluorescent dye. The results show that HLA class I polymorphisms might predispose people to develop infectious mononucleosis upon EBV infection. (3712)

J. Biol. Chem. 281, 30001–30014. Identification of a domain in the V0 subunit d that is critical for coupling of the yeast vacuolar proton-translocating ATPase. 2006

Owegi, M.A., Pappas, D.L., Finch, M.W. Jr., Bilbo, S.A., Resendiz, C.A., Jacquemin, L.J., Warrier, A., Trombley, J.D., McCulloch, K.M., Margalef, K.L., Mertz, M.J., Storms, J.M., Damin, C.A. and Parra, K.J.

Notes: The authors generated truncations of subunit d of a vacuolar proton-translocating ATPase pump to examine the protein's function. The N- and C-termini were required for subunit stability as well as pump function and assembly. Function was restored to the C-terminal deletions of subunit d by creating a chimeric protein with the C-terminus of a subunit d homolog from Thermus thermophilus. Three tandem repeats of a hemagglutinin (HA3) epitope were amplified and inserted at the N-terminus so that the chimeric protein could be visualized by Western blot with an anti-HA antibody. Initial amplification of the HA3 epitope and amplifications to confirm the orientation of the epitope were performed using GoTaq®Green Master Mix. (3720)
