Accurate RT-qPCR gene expression analysis on cell culture lysates [PDF]

, 2012
Gene expression quantification on cultured cells using the reverse transcription quantitative polymerase chain reaction (RT-qPCR) typically involves an RNA purification step that limits sample processing throughput and precludes parallel analysis of ...

Cellular liquid biopsy provides unique chances for disease monitoring, preclinical model generation and therapy adjustment in rare salivary gland cancer patients

Molecular Oncology, EarlyView.
We quantified and cultured circulating tumor cells (CTCs) of 62 patients with various cancer types and generated CTC‐derived tumoroid models from two salivary gland cancer patients. Cellular liquid biopsy‐derived information enabled molecular genetic assessment of systemic disease heterogeneity and functional testing for therapy selection in both ...

Norovirus Proteinase-Polymerase and Polymerase Are Both Active Forms of RNA-Dependent RNA Polymerase [PDF]

Journal of Virology, 2005
ABSTRACT In vitro mapping studies of the MD145 norovirus ( Caliciviridae ) ORF1 polyprotein identified two stable cleavage products containing the viral RNA-dependent RNA polymerase (RdRp) domains: ProPol (a precursor comprised of both the proteinase and polymerase) and Pol (the mature polymerase).

New Anti-Influenza Agents: Targeting the Virus Entry and Genome Transcription

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2019
Introduction: The emergence and spread of the pandemic H1N1 influenza virus in 2009 indicates a limitation in the strategy to control the infection, despite a long-established vaccination programme and approved antivirals.

NeoRdRp2 with improved seed data, annotations, and scoring

Frontiers in Virology
RNA-dependent RNA polymerase (RdRp) is a marker gene for RNA viruses; thus, it is widely used to identify RNA viruses from metatranscriptome data. However, because of the high diversity of RdRp domains, it remains difficult to identify RNA viruses using ...

Conformational Selection and Induced Fit for RNA Polymerase and RNA/DNA Hybrid Backtracked Recognition

Frontiers in Molecular Biosciences, 2015
RNA polymerase catalyzes transcription with a high fidelity. If DNA/RNA mismatch or DNA damage occurs downstream, a backtracked RNA polymerase can proofread this situation. However, the backtracked mechanism is still poorly understood.

Inhibition of native hepatitis C virus replicase by nucleotide and non-nucleoside inhibitors [PDF]

, 2004
A number of nucleotide and non-nucleoside inhibitors of HCV polymerase are currently under investigation as potential antiviral agents to treat HCV-infected patients.

Integrative analysis of circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients: a comprehensive approach

Molecular Oncology, EarlyView.
This study simultaneously investigated circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients. The elevated expression of JUNB and CXCR4 in CTCs was a poor prognostic factor for SCLC patients, whereas exosomal overexpression of these biomarkers revealed a high discrimination ability of patients from healthy individuals,

RNA Polymerase as a Molecular Motor [PDF]

Cell, 1998
The existing single-molecule studies of E. coli RNAP suggest a number of promising avenues for future research into transcription mechanisms in both prokaryotes and eukaryotes. First, if measurements can be made precisely enough to resolve 1 bp steps with high time resolution, the experiments could discriminate between alternative translocation ...

RNA elements directing in vivo assembly of the 7SK/MePCE/Larp7 transcriptional regulatory snRNP [PDF]

, 2013
Through controlling the nuclear level of active positive transcription elongation factor b (P-TEFb), the 7SK small nuclear RNA (snRNA) functions as a key regulator of RNA polymerase II transcription.
