Allosteric collaboration between elongation factor G and the ribosomal L1 stalk directs tRNA movements during translation [PDF]

, 2009
Determining the mechanism by which transfer RNAs (tRNAs) rapidly and precisely transit through the ribosomal A, P and E sites during translation remains a major goal in the study of protein synthesis. Here, we report the real-time dynamics of the L1 stalk, a structural element of the large ribosomal subunit that is implicated in directing tRNA ...

Next-generation Sequencing of 16S Ribosomal RNA Gene Amplicons [PDF]

Journal of Visualized Experiments, 2014
One of the major questions in microbial ecology is "who is there?" This question can be answered using various tools, but one of the long-lasting gold standards is to sequence 16S ribosomal RNA (rRNA) gene amplicons generated by domain-level PCR reactions amplifying from genomic DNA.

Response to neoadjuvant chemotherapy in early breast cancers is associated with epithelial–mesenchymal transition and tumor‐infiltrating lymphocytes

Molecular Oncology, EarlyView.
Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

The complete mitochondrial genome of Glossaulax reiniana (Littorinimorpha: Naticidae)

Mitochondrial DNA. Part B. Resources, 2018
In the present study, the complete mitochondrial genome of Glossaulax reiniana was determined using the next-generation sequencing. The circular genome was found to be 15,254 bp in length and had an overall nucleotide composition of 30.6% A, 14.1% C, 15 ...

Frequency of Bacetrial Content Finding in Persistant Periapical Lesions

Acta Stomatologica Croatica, 2017
Objectives: To determine the percentage of persistant apical lesions positive for bacterial nucleic acids, to detect microorganisms difficult to cultivate in persistant apical lesions by PCR and relate them to endodontic failure, clinical symptoms and ...

A systematic search for discriminating sites in the 16S ribosomal RNA gene [PDF]

Microbial Informatics and Experimentation, 2014
The 16S rRNA is by far the most common genomic marker used for prokaryotic classification, and has been used extensively in metagenomic studies over recent years. Along the 16S gene there are regions with more or less variation across the kingdom of bacteria.

Transcriptome‐wide analysis of circRNA and RBP profiles and their molecular relevance for GBM

Molecular Oncology, EarlyView.
CircRNAs are differentially expressed in glioblastoma primary tumors and might serve as therapeutic targets and diagnostic markers. The investigation of circRNA and RNA‐binding proteins (RBPs) interactions shows that distinct RBPs play a role in circRNA biogenesis and function.

MOLECULAR IDENTIFICATION OF SEVERAL CLINICALLYIMPORTANT BACTERIA INCLUDING ENTEROBACTERIA BYPARTIAL 16S RIBOSOMAL RNA GENE SEQUENCE COMPARISON

Zdravniški Vestnik, 2008
BACKGROUND The correct identification of bacterial isolates is paramount for the correct diagnosis andtreatment of patients. The standard approach for bacterial identification relies on phenotypic tests, which are often time-consuming and unreliable when

The impact of molecular biology on assessment of water quality: advantages and limitations of current techniques [PDF]

, 1997
The advent of molecular biology has had a dramatic impact on all aspects of biology, not least applied microbial ecology. Microbiological testing of water has traditionally depended largely on culture techniques.

Microbial residence time is a controlling parameter of the taxonomic composition and functional profile of microbial communities. [PDF]

, 2019
A remaining challenge within microbial ecology is to understand the determinants of richness and diversity observed in environmental microbial communities.
