Appl. Environ. Microbiol. 77, 2113–21. General suppression of Escherichia coli O157:H7 in sand-based dairy livestock bedding. 2011

Westphal, A., Williams, M.L., Baysal-Gurel, F., LeJeune, J.T. and McSpadden Gardener, B.B.

Notes: The authors investigated the suppression of E. coli O157:H7 in sand-based livestock bedding and hypothesized that suppression of E. coli O157:H7 growth was mediated by an environmentally stable population of pathogen-suppressing bacteria. These bacteria were identified by terminal restriction fragment length polymorphism (T-RFLP) analysis of amplified 16S rRNA gene sequences isolated from used bedding followed by cloning and sequencing of the most abundant terminal restriction fragments. Amplifications were performed using the GoTaq® Flexi DNA Polymerase, then PCR products were cloned into the pGEM®-T Easy Vector. The PureYield™ Plasmid Miniprep System was used to purify plasmids for sequencing. (4165)

Genetics 184, 119–28. Detection, validation, and downstream analysis of allelic variation in gene expression. 2010

Ciobanu, D.C., Lu, L., Mozhui, K., Wang, X., Jagalur, M., Morris, J.A., Taylor, W.L., Dietz, K., Simon, P. and Williams, R.W.

Notes: Sequence variation within a gene, such as single nucleotide polymorphisms (SNPs), can lead to differences in expressions levels of corresponding mRNAs; genes that are self-regulated by this mechanism (cis modulation) are difficult to identify accurately with existing techniques. The authors used bioinformatic and molecular approaches to estimate error rates when identifying cis-modulated transcripts and developed a simple method to detect these transcripts in C57BL/6J F1 hybrid mice. This method, which they named allelic specific expression, is RT-PCR-based and uses PCR primers that flank an informative SNP to quantify the differential expression levels of transcripts. GoTaq® Flexi DNA Polymerase was used in the PCR. (4051)

Vet. Pathol. 47, 163–6. Peliosis hepatis in cats is not associated with Bartonella henselae infections. 2010

Buchmann, A.U., Kempf, V.A., Kershaw, O. and Gruber, A.D.

Notes: The vasculoproliferative disorder peliosis hepatis has been linked to Bartonella henselae infection in humans and dogs. The authors sought to determine if this is true in cats, the natural reservoir for B. henselae, using immunohistochemistry (IHC) and PCR. Tissue sections from 26 cats with peliosis hepatis were formalin-fixed and paraffin-embedded and subjected to IHC using a B. henselae-specific antibody. To detect B. henselae DNA, PCR was performed using GoTaq® Flexi DNA Polymerase, genus-specific primers for the pap31 gene of Bartonella, 1mM MgCl2 and total DNA isolated from 8µm paraffin-embedded tissue sections. The presence of Bartonella DNA was confirmed by PCR using species-specific primers that target the B. henselae heat-shock protein (htrA). These studies found no link between B. henselae infection and peliosis heptis in cats. (4094)

Clin. Chem. 55, 748–56. Coamplification at lower denaturation temperature-PCR increases mutation-detection selectivity of TaqMan-based real-time PCR. 2009

Li, J., Wang, L., Jänne, P.A. and Makrigiorgos, GM.

Notes: The authors describe a new form of PCR, co-amplification at lower denaturation temperature PCR (COLD-PCR), to detect low-level somatic mutations. This technique is based on the facts that a) each DNA sequence has a critical denaturation temperature (Tc), which is lower than the melting temperature (Tm) and below which PCR efficiency decreases dramatically and b) Tc depends on DNA sequence. The authors used GoTaq® Flexi DNA Polymerase and mutation-specific TaqMan® probes for tumor protein 53 (TP53) and epidermal growth factor receptor (EGFR) to detect low-level somatic mutations in a mixture of wildtype and mutant DNAs. Conventional TaqMan® technology can detect mutant alleles at an abundance of 10–20% of that of the wildtype allele; using COLD-PCR the authors were able to increase selectivity 15- to 30-fold, detecting as little as 0.8% mutuant alleles.

Clin. Can. Res. 15, 7562–70. Smoking-related gene expression in laser capture-microdissected human lung. 2009

Tan, X.L., Wang, T., Xiong, S., Kumar, S.V., Han, W. and Spivack, S.D.

Notes: The authors characterized differential expression of several carcinogen metabolism genes in human alveolar compartment (AC) and bronchial epithelial compartment (BEC) lung tissues in smokers, former smokers and people who have never smoked. They combined laser capture microdissection (LCM) and quantitative RT-PCR. RNA was isolated from paired microdissected malignant and nonmalignant lung tissue, 100ng of total RNA was reverse transcribed in a 20µl reaction, then 1µl of cDNA was amplified by real-time PCR using an ABI PRISM® 7500HT sequence detection system, GoTaq® Flexi DNA Polymerase and gene-specific primers. The expression level for each gene was normalized using glyceraldehyde-3-phosphate dehydrogenase (GAPDH). The results showed that expression of cytochrome P450 1B1 and glutathione-S-transferase P1 in AC, but not BEC, tissue was strongly associated with exposure to tobacco. (4095)

Biol. Reprod. 79, 594–7. Can bovine in vitro-matured oocytes selectively process X- or Y-sorted sperm differentially? 2008

Bermejo-Alvarez, P., Rizos, D., Rath, D., Lonergan, P. and Gutiérrez-Adán, A.

Notes: To determine whether oocytes are able to select X-bearing or Y-bearing spermatozoa, the authors performed in vitro fertilization of bovine oocytes with X-sorted semen, Y-sorted semen, a mixture of X- and Y-sorted semen, and unsorted semen. The gender of the resulting embryos was determined by amplifying two DNA targets: a Y chromosome-specific target for gender assignment and a bovine-specific satellite sequence as a control. PCRs were performed using GoTaq® Flexi DNA Polymerase (1 unit per 25µl reaction), and amplified products were analyzed by agarose gel electrophoresis followed by ethidium bromide staining. (3881)

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. 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)
