Chromosomal Position of Ribosomal Protein Genes Affects Long-Term Evolution of Vibrio cholerae

mBio, 2023
It is unclear how gene order within the chromosome influences genome evolution. Bacteria cluster transcription and translation genes close to the replication origin (oriC).

Stochastic kinetics of ribosomes: single motor properties and collective behavior [PDF]

Physical Review E, vol.80, 011908 (2009), 2009
Synthesis of protein molecules in a cell are carried out by ribosomes. A ribosome can be regarded as a molecular motor which utilizes the input chemical energy to move on a messenger RNA (mRNA) track that also serves as a template for the polymerization of the corresponding protein.

RNAmmer: consistent and rapid annotation of ribosomal RNA genes

Nucleic Acids Research, 2007
The publication of a complete genome sequence is usually accompanied by annotations of its genes. In contrast to protein coding genes, genes for ribosomal RNA (rRNA) are often poorly or inconsistently annotated.

Integrative systems‐level analysis reveals a contextual crosstalk between hypoxia and global metabolism in human breast tumors

Molecular Oncology, EarlyView.
Breast tumor samples scored for metabolic deregulation (M1 to M3) were given a hypoxia score (HS). The highest HS occurred in patients with strongest metabolic deregulation (M3), supporting tumor aggressiveness. HS correlated with the highest number of metabolic pathways in M1. This suggests hypoxia to be an early event in metabolic deregulation.

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.

Genome Mining Enabled by Biosynthetic Characterization Uncovers a Class of Benzoxazolinate‐Containing Natural Products in Diverse Bacteria

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Benzoxazolinate is a rare bis‐heterocyclic moiety that interacts with proteins and DNA. It was found that a putative acyl AMP‐ligase mediates the last cyclization step to afford benzoxazolinate. The enzyme was then used as a probe for genome mining, which led to the discovery of a new class of benzoxazolinate‐containing compounds in diverse bacteria ...

Ribosomal protein S27-like is a physiological regulator of p53 that suppresses genomic instability and tumorigenesis

eLife, 2014
Cell-based studies showed that several Mdm2-binding ribosomal proteins, upon overexpression, stabilize and activate p53. In contrast, here we show in a mouse knockout study that Mdm2-binding ribosomal protein S27-like (Rps27l), upon disruption, activates

Involvement of Mitochondrial Ribosomal Proteins in Ribosomal RNA-mediated Protein Folding [PDF]

Journal of Biological Chemistry, 2011
The peptidyl transferase center of the domain V of large ribosomal RNA in the prokaryotic and eukaryotic cytosolic ribosomes acts as general protein folding modulator. We showed earlier that one part of the domain V (RNA1 containing the peptidyl transferase loop) binds unfolded protein and directs it to a folding competent state (FCS) that is released ...

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.

RNAlater facilitates remote sampling of aquaculture Atlantic salmon liver for proteomic analysis

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 578-586, December 2022., 2022
Graphical Abstract Proteomes of similar sizes were obtained in samples preserved by snap‐freezing or RNAlater. Proteins involved in transcriptional and translational machinery were affected in RNAlater stored samples. Abundance of published markers for heat and oxidative stress was not affected by snap‐freezing or RNAlater.
