Three Ribosomal Operons of Escherichia coli Contain Genes Encoding Small RNAs That Interact With Hfq and CsrA in vitro

Frontiers in Microbiology, 2021
Three out of the seven ribosomal RNA operons in Escherichia coli end in dual terminator structures. Between the two terminators of each operon is a short sequence that we report here to be an sRNA gene, transcribed as part of the ribosomal RNA primary ...

Fluorescent protein tagging confirms the presence of ribosomal proteins atDrosophilapolytene chromosomes [PDF]

, 2013
\ud \ud Most ribosomal proteins (RPs) are stoichiometrically incorporated into ribosomal subunits and play essential roles in ribosome biogenesis and function.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Magnification of Genes Coding for Ribosomal RNA in Saccharomyces cerevisiae [PDF]

, 1977
When a strain of Saccharomyces cerevisiae monosomic for chromosome I and initially deficient for 25% of the genes coding for ribosomal RNA is repeatedly subcultured, the number of these genes increases to and remains stable at the number in the wild type.

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

Molecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Pre-Ribosomal RNA Processing in Human Cells: From Mechanisms to Congenital Diseases

Biomolecules, 2018
Ribosomal RNAs, the most abundant cellular RNA species, have evolved as the structural scaffold and the catalytic center of protein synthesis in every living organism.

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells

Molecular Oncology, EarlyView.
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...

Ribosomal transcription is regulated by PGC-1alpha and disturbed in Huntington’s disease

Scientific Reports, 2017
PGC-1α is a versatile inducer of mitochondrial biogenesis and responsive to the changing energy demands of the cell. As mitochondrial ATP production requires proteins that derive from translation products of cytosolic ribosomes, we asked whether PGC-1α ...

Structural basis of ribosomal RNA transcription regulation

Nature Communications, 2021
Ribosomal RNA (rRNA) expression is regulated at the initiation stage of RNA synthesis. Here, the authors report cryo-EM structures of E. coli RNA polymerase and rRNA promoter complex with DksA/ppGpp on the way to open complex formation, identifying key ...
