Bayesian inference of polymerase dynamics over the exclusion process [PDF]

arXiv, 2021
Transcription is a complex phenomenon that permits the conversion of genetic information into phenotype by means of an enzyme called RNA polymerase, which erratically moves along and scans the DNA template. We perform Bayesian inference over a paradigmatic mechanistic model of non-equilibrium statistical physics, i.e., the asymmetric exclusion ...

The Arabidopsis Chromatin-Modifying Nuclear siRNA Pathway Involves a Nucleolar RNA Processing Center [PDF]

, 2006
SummaryIn Arabidopsis thaliana, small interfering RNAs (siRNAs) direct cytosine methylation at endogenous DNA repeats in a pathway involving two forms of nuclear RNA polymerase IV (Pol IVa and Pol IVb), RNA-DEPENDENT RNA POLYMERASE 2 (RDR2), DICER-LIKE 3

RNA-Dependent RNA Polymerase Activity in Influenza Virions [PDF]

Proceedings of the National Academy of Sciences, 1971
An RNA-dependent RNA polymerase activity has been detected in purified preparations of influenza virus. In contrast to the replicase activity induced in influenza-infected cells, the virion-associated enzyme has an absolute requirement for Mn ++ .

Clinical applications of next‐generation sequencing‐based ctDNA analyses in breast cancer: defining treatment targets and dynamic changes during disease progression

Molecular Oncology, EarlyView.
Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

Computationally repurposed drugs and natural products against RNA dependent RNA polymerase as potential COVID-19 therapies

Molecular Biomedicine, 2021
Repurposing of existing drugs and drug candidates is an ideal approach to identify new potential therapies for SARS-CoV-2 that can be tested without delay in human trials of infected patients.

How the Avidity of Polymerase Binding to the -35/-10 Promoter Sites Affects Gene Expression [PDF]

, 2019
Although the key promoter elements necessary to drive transcription in Escherichia coli have long been understood, we still cannot predict the behavior of arbitrary novel promoters, hampering our ability to characterize the myriad of sequenced regulatory architectures as well as to design novel synthetic circuits.

Transcription-translation machinery -- an autocatalytic network coupling all cellular cycles and generating a plethora of growth laws [PDF]

arXiv, 2021
Recently discovered simple quantitative relations, known as bacterial growth laws, hint on the existence of simple underlying principles at the heart of bacterial growth. In this work, we provide a unifying picture on how these known relations, as well as new relations that we derive, stems from a universal autocatalytic network common to all bacteria,

Mechanism for Coordinated RNA Packaging and Genome Replication by Rotavirus Polymerase VP1 [PDF]

, 2011
Rotavirus RNA-dependent RNA polymerase, VP1, catalyzes RNA synthesis within a subviral particle. This activity depends on core shell protein VP2. A conserved sequence at the 3′ end of plusstrand RNA templates is important for polymerase association and ...

Interstitial Contacts in an RNA-Dependent RNA Polymerase Lattice [PDF]

Journal of Molecular Biology, 2011
Catalytic activities can be facilitated by ordered enzymatic arrays that co-localize and orient enzymes and their substrates. The purified RNA-dependent RNA polymerase from poliovirus self-assembles to form two-dimensional lattices, possibly facilitating the assembly of viral RNA replication complexes on the cytoplasmic face of intracellular membranes.

Circulating tumor cells: advancing personalized therapy in small cell lung cancer patients

Molecular Oncology, EarlyView.
Small cell lung cancer (SCLC) is an aggressive form of lung cancer that spreads rapidly to secondary sites such as the brain and liver. Cancer cells circulating in the blood, “circulating tumor cells” (CTCs), have demonstrated prognostic value in SCLC, and evaluating biomarkers on CTCs could guide treatment decisions such as for PARP inhibitors ...
