PLoS Genet. 8, e1002941. MOV10 RNA helicase is a potent inhibitor of retrotransposition in cells. 2012

Goodier, J.L., Cheung, L.E. and Kazazian, H.H. Jr.

Notes: To better understand the role MOV10 protein, a putative RNA helicase and component of the RNA–induced silencing complex (RISC), in reducing retrotransposon activity, 293T human embryonic kidney cells expressing MOV10 and one of three retrotransposons (LINE1 (L1), Alu or SVA) were lysed in a buffer that included RNasin® Ribonuclease Inhibitor, and FLAG-tagged L1 complexes immunoprecipitated and analyzed by mass spectrometry. Several retrotransposon assays were conducted using FuGENE® HD Transfection Reagent for transfected constructs into 293T, HeLa and HeLa-HA cells. (4255)

Nucl. Acids Res. Dec 8, Epub ahead of print. Protein-mediated protection as the predominant mechanism for defining processed mRNA termini in land plant chloroplasts. 2011

Zhelyazkhova, P., Hammani, K., Rojas, M., Voelker, R., Vargas-Suárez, M., Börner, T., and Barkan, A.

Notes: Pentatricopeptide repeat (PPR) proteins are helical repeat proteins that bind specific RNA segments and protect the adjacent RNA by serving as a barrier to exoribonucleases. This study showed that protection by PPR or PPR-like proteins is the predominant mechanism for defining the positions of processed 5′ and intercistronic mRNA termini in land plant chloroplasts. The authors used RNasin® Ribonuclease Inhibitor in binding reactions between labeled RNA and PPR proteins prior to Gel mobility shift assays. They also used the pGEM®-T Vector to clone various 3´ RNA terminal sequences amplified by RT-PCR. (4185)

FASEB J. 21, 1893–1901. Low expression of COX-2, reduced cumulus expansion, and impaired ovulation in SULT1E1-deficient mice. 2007

Gershon, E., Hourvitz, A., Reikhav, S., Maman, E. and Dekel, N.

Notes: The authors investigated the role of estrogen inactivation by the SULT1E1-encoded estrogen sulfotransferase in ovulation in mice. Semiquantitative RT-PCR was used to characterize the temporal and tissue-specific expression of SULT1E1 mRNA in ovulating mice. First-strand cDNA synthesis was performed at 37°C for 2 hours using 7.5µg of total RNA, 1µl (0.5µg) of oligo(dT)15, 40 units of RNasin® Ribonuclease Inhibitor and 200 units of M-MLV Reverse Transcriptase.

Infect. Immun. 75, 3478–89. Reversal of the antichlamydial activity of putative type III secretion inhibitors by iron. 2007

Slepenkin, A., Enquist, P.A., Hägglund, U., de la Maza, L.M., Elofsson, M. and Peterson, E.M.

Notes: The authors screened members of a class of acylated hydrazones of salicylaldehydes (INPs) to characterize their ability to inhibit growth of Chlamydia by affecting the type III secretion (T3S) system, a potent virulence mechanism. Expression levels of various T3S genes and gene markers of early, middle and late developmental cycles were examined by RT-PCR in Chlamydia trachomatis-infected HeLa 229 cells in the presence and absence of INPs. HeLa229 RNA was isolated at 4, 8, 24 and 36 hours postinfection, treated with RQ1 RNase-Free DNase and amplified using the Access RT-PCR System in the presence of 0.5 units of RNasin RNase Inhibitor. Each set of experiments included a no-reverse transcriptase control reaction to control for DNA contamination and a positive control reaction using the Positive Control RNA with Carrier and control primers supplied with the kit.

Amplification of 408bp of ribosomal RNA 36B4 was performed as control. The PCR mixture consisted of 1.25U GoTaq® DNA Polymerase, 1X PCR buffer (10mM Tris-HCl, 50mM KCl), 2.5mM MgCl2, 0.2mM each dNTP, 0.6μM of each PS2 primer or cathepsin D primer and 0.2μM of each 36B4 primer. PCR was performed for 20 cycles at 95°C for 1 minute, 59°C for 2 minutes and 72°C for 1 minute. Ten microliters of the PCR products were separated on a 1.2% agarose gel. (3377)
