Gene 641, 151–60. Individual effects of the copia and gypsy enhancer and insulator on chromatin marks, eRNA synthesis, and binding of insulator proteins in transfected genetic constructs 2018

Fedoseeva, D.M., Kretova, O.V., Gorbacheva, M.A., Tchurikov, N.A.

Notes: The function of enhancer and insulator elements for the mobile elements copia and gypsy are characterized. To determine the function of these elements, cells were transfected with luciferase constructs with enhancer and insulator elements using the TransFast™ Transfection Reagent. Luciferase activity was monitored with the Dual-Luciferase® Reporter Assay. Enhancers stimulated the synthesis of long enhancer RNAs (eRNAs) and histone methylation and acetylation marks. The presence of insulator sequence reduced eRNA synthesis. (5089)

Am. J. Hum. Genet. 97, 555-66. Biallelic mutations in nuclear pore complex subunit NUP107 cause early-childhood-onset steroid-resistant nephrotic syndrome. 2015

Niyake, N., Tsukaguchi, H., Koshimizu, E., Shono, A., Matsunaga, S., Shiina, M., Mimura, Y., Imamura, S., Hirose, T., Okudela, K., Nozu, K., Akioka, Y., Hattori, M., Yoshikawa, N., Kitamura, A., Cheong, H.I., Kagami, S., Yamashita, M., Fugita, A., Miyatake, S., Tsurusaki, Y., Nakashima, M., Saitsu, H., Ohashi, K., Imamoto, N. and Ryo, A.

Notes: The interaction of NUP107 and NUP133 were investigated by several means. First, in vitro expressed, biotinylated NUP107 was mixed with FLAG-tagged NUP133 and pulled down with Streptavidin MagneSphere® Particles and blotted for reaction with Anti-FLAG antibodies. HeLa cells were transfected with a GFP-NUP107 fusion vector using ViaFect™ Transfection Reagent (no details provided) and immunoprecipitated then blotted to identify NUP133 in the pull down. Subcellular localization of GFP-NUP107 was examined as well. RT-PCR analysis of nup107 splicing variants in zebrafish relied on M-MLV Reverse Transcriptase for cDNA synthesis. (4675)

J. Biol. Chem. 282, 9883–94. Cell confluence-induced activation of signal transducer and activator of transcription-3 (Stat3) triggers epithelial dome formation via augmentation of sodium hydrogen exchanger-3 (NHE3) expression. 2007

Su, H.W., Yeh, H.H., Wang, S.W., Shen, M.R., Chen, T.L., Kiela, P.R., Ghishan, F.K. and Tang, M.J

Notes: The authors tested their hypothesis that Na+-H+ exchangers (NHE) are involved in the formation of multicullar dome structures in confluent Madin-Darby canine kidney (MDCK) cells and that the Stat3 pathway is involved in regulation of NHEs. The authors performed semi-quantitative RT-PCR to monitor NHE3 mRNA levels in MDCK cells expressing a constitutive Stat3 mutant or a dominant-negative Stat3 mutant. The reverse transcription step was performed using Promega M-MLV Reverse Transcriptase. RAlso, Stat3 activities in low-density cultures and high-density cultures were compared using a reporter gene assay. Four copies of the Stat3-binding site were cloned upstream of a firefly luciferase reporter gene, and the resulting vector, along with the pRL-TK Vector for normalization, were transfected into MDCK cells. Luciferase activities were measured using the Dual-Luciferase Reporter Assay System. (3910)

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. Endocrinol. 197, 201–12. Neonatal exposure to bisphenol A modifies the abundance of estrogen receptor alpha transcripts with alternative 5'-untranslated regions in the female rat preoptic area. 2007

Monje, L., Varayoud, J., Luque, E.H. and Ramos, J.G.

Notes: The authors investigated the effect of neonatal bisphenol A (BPA) exposure in rats on expression of estrogen receptor α (ERα) transcripts. Alternative ERα transcripts in preoptic area of treated and untreated rats were quantified using real-time RT-PCR. Reverse transcription was performed using 4µg of total RNA, 200pmol random primers and 300 units M-MLV Reverse Transcriptase. Real-time PCR was performed using SYBR® Green I to quantify amplified products. To determine if the changes in BPA-induced ERα transcript expression were caused by DNA methylation, the methylation status of the five ERα promoters was examined by bisulfite modification. Genomic DNA was isolated from rat tissue using the Wizard® Genomic DNA Purification Kit, denatured with NaOH, then treated with hydroquinone and sodium bisulfite. Prior to methylation-specific PCR, DNA was cleaned up using the Wizard® DNA Purification Resin as directed by the manufacturer. PCR products were cleaned up again using the Wizard® SV Gel and PCR Clean-Up System, then subjected to restriction enzyme digestion and agarose gel electrophoresis to reveal methylation-dependent sequence differences.

Mol. Cell. Endocrinol. 264, 50-60. Novel estrogen receptor beta transcript variants identified in human breast cancer cells affect cell growth and apoptosis of COS-1 cells. 2007

Treeck, O., Pfeiler ,G., Horn, F., Federhofer, B., Houlihan, H., Vollmer, A., and Ortmann, O.

Notes: This study identified two novel transcript variants of the estrogen receptor ERβ that were expressed in the ERα-negative breast cancer cell line MDA-MD-231. These variants were identified after amplification of ERβ transcripts from the breast cancer cell line by RT-PCR. The amplification products were then excised from gels and subcloned into the pTARGET™ Mammalian Expression Vector prior to sequencing. COS1 cells, which do not express the estrogen receptor, were then stably transfected with full-length ERβ or one of the splice variants and the effects on cell proliferation, apoptosis, and estrogen response were evaluated. In COS1 cells expressing either ERβ or the transcript variants cell proliferation decreased and basal apoptosis (caspase 3/7 activity) increased, compared to cells transfected with vector alone. Exposure to therapeutic doses of tamoxifen induced apoptosis in cells expressing the full-length ERβ but not in cells expressing either of the variant isoforms. (3618)

Guyonnet-Duperat, V., Geverink, N., Plastow, G.S., Evans, G., Ousova, O., Croisetiere, C., Foury, A., Richard, E., Mormede, P. and Moisan, M.P.

Notes: In this study, the effects of amino acid substitutions in porcine corticosteroid-binding globulin gene (Cbg) were tested on CBG binding and affinity. Genomic DNA was isolated from whole blood of 92 female pigs studied. Cbg cDNA was obtained by reverse transcribing pig liver total RNA using M-MLV Reverse Transcriptase followed by PCR. The 1257pb cDNA PCR product was ligated into the pTARGET™ Mammalian Expression Vector. The GeneEditor™ in vitro Site-Directed Mutagenesis System was used to introduce four different codon substitutions in the Cbg cDNA. Once created, the mutated and unmodified Cbg cDNA constructs were transfected into HEK-293T (human embryonic kidney) cells. After 48 hours, the supernatant was collected to analyze secreted CBG.

Stem Cells 24, 781-792. Human umbilical cord matrix stem cells: Preliminary characterization and effect of transplantation in a rodent model of Parkinson's disease. 2006

Weiss, M.L., Medicetty, S., Bledsoe, A.R., Rachakatla, R.S., Choi, M., Merchav, S., Luo, Y., Rao, M.S., Velagaleti, G. and Troyer, D.

Notes: The gene expression profile of human umbilical cord matrix stem (UCMS) cells was determined by microarray analysis and confirmed by RT-PCR. The 50 most highly expressed genes in UCMS cells tended to fall into several categories: genes associated with neurotrophic effects and morphogenesis, the three germ layers, the undifferentiated state of embryonic stem cells and extracellular adhesion molecules. The biotin dUTP-labeled cDNA probes used to query the UCMS cell microarray were synthesized using 200 units of M-MLV Reverse Transcriptase and 4µg of total RNA. (3469)

Clin. Chem. 52, 634-642. Quantification of mRNA in whole blood by assessing recovery of RNA and efficiency of cDNA synthesis. 2006

Mitsuhashi, M., Tomozawa, S., Endo, K. and Shinagawa, A.

Notes: The authors developed a method to reverse transcribe poly(A)+ RNA from leukocytes without using oligo(dT) immobilized on a 96-well plate. Four RNA targets, as well as a synthetic control RNA, were reverse transcribed using MMLV Reverse Transcriptase (1X reverse transcription buffer [50mM KCl, 10mM Tris-HCl (pH 8.3), 5.5mM MgCl2, 1nL/µL Tween 20], 1.25 mM each dNTP and 4 units of Recombinant RNasin® Ribonuclease Inhibitor), then quantitated by real-time quantitative PCR. The authors varied the concentration of MMLV Reverse Transcriptase, incubation time, and primer/template ratio] to obtain the maximum yield. Small quantities of MMLV Reverse Transcriptase were sufficient to reverse transcribe short synthetic RNA and abundant RNAs, but approximately 100 units was required for other RNAs. The synthetic control RNA was synthesized using the T7 RiboMAX™ Express Large Scale RNA Production System. (3456)
