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.

Uirusu, 2001 The T7 bacteriophage encodes a single-subunit RNA polymerase of 99 kDa that transcribes the phage's genes during its lytic growth in Escherichia coli. The T7 RNA polymerase is structurally similar to DNA polymerases, reverse transcriptases, and RNA-directed RNA polymerases, and these structural similarities define a polymerase superfamily that includes

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,

Stochastic Models of Regulation of Transcription in Biological Cells [PDF]
arXiv, 2022 In this paper we study an important global regulation mechanism of transcription of biological cells using specific macro-molecules, 6S RNAs. The functional property of 6S RNAs is of blocking the transcription of RNAs when the environment of the cell is not favorable.

Theoretical model of transcription based on torsional mechanics of DNA template [PDF]
Journal of Statistical Physics 174 (2019) 1316, 2018 Transcription is the first step of gene expression, in which a particular segment of DNA is copied to RNA by the enzyme RNA polymerase (RNAP). Despite many details of the complex interactions between DNA and RNA synthesis disclosed experimentally, much of physical behavior of transcription remains largely unknown.

Evolutionary connection between the catalytic subunits of DNA-dependent RNA polymerases and eukaryotic RNA-dependent RNA polymerases and the origin of RNA polymerases [PDF]
BMC Structural Biology, 2003 The eukaryotic RNA-dependent RNA polymerase (RDRP) is involved in the amplification of regulatory microRNAs during post-transcriptional gene silencing. This enzyme is highly conserved in most eukaryotes but is missing in archaea and bacteria. No evolutionary relationship between RDRP and other polymerases has been reported so far, hence the origin of ...

Molecular Oncology, EarlyView.VASP was found to be overexpressed in metastatic oral squamous cell carcinoma (OSCC) tissues. Notably, PTTG1‐ and VASP‐deficient OSCC cells demonstrated suppressed metastatic properties by disrupting the interaction between the cytoskeleton and focal adhesion (FAs) in the filopodia region.

Klebsiella Phage KP34 RNA Polymerase and Its Use in RNA Synthesis
Frontiers in Microbiology, 2019 We have characterized the single subunit RNA polymerase from Klebsiella phage KP34. The enzyme is unique among known bacteriophage RNA polymerases in that it recognizes two unrelated promoter sequences, which provided clues for the evolution of phage ...
