Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Skeletal muscle ribosome analysis: A comparison of common assay methods and utilization of a novel RiboAb antibody cocktail

Physiological Reports
While total RNA concentrations putatively represent ribosome content, there is a need to homologize various quantification approaches. Thus, total RNA concentrations ([RNA]) provided through UV–Vis spectroscopy (UV), fluorometry‐only (Fluor), and ...

Identification of Scopulariopsis Species by Partial 28S rRNA Gene Sequence Analysis

Polish Journal of Microbiology, 2013
The genus Scopulariopsis contains over 30 species of mitosporic moulds, which although usually saprophytic may also act as opportunistic pathogens in humans. They have mainly been associated with onychomycosis, and only sporadically reported as a cause of deep tissue infections or systemic disease. Identification of Scopulariopsis species still largely

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

Molecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

Structure of mottse rRNA precursors.Complete sequence and potential folding of the spacer regions between 18S and 28S rRNA

Nucleic Acids Research, 1983
We have determined the complete nucleotide sequence of the regions of mouse ribosomal RNA transcription unit which separate mature rRNA genes. These internal transcribed spacers (ITS) are excised from rRNA precursor during ribosome biosynthesis. ITS 1, between 18S and 5.8S rRNA genes, is 999 nucleotides long.

R5 Retrotransposons Insert into a Family of Infrequently Transcribed 28S rRNA Genes of Planaria [PDF]

Molecular Biology and Evolution, 2003
A small (100 bp) region of the 28S rRNA gene has been shown to serve as the target site for the insertion of non-long terminal repeat (non-LTR) retrotransposons in both arthropods and nematodes. Here we characterize a lineage of non-LTR retrotransposons that inserts into this target site in the phylum Platyhelminthes. Dugesiid planaria contain elements,

The impact of leukocyte‐associated RNA retention on platelet RNA‐based cancer detection

Molecular Oncology, EarlyView.
Platelets carry RNA signals that may help detect cancer, but platelet samples can also retain RNA from white blood cells. We found that this retained white blood cell signal did not significantly affect machine learning cancer classification, suggesting that the cancer‐related RNA signal in platelets is largely independent of leukocyte‐associated RNA ...

Fine Mapping of 28S rRNA Sites Specifically Cleaved in Cells Undergoing Apoptosis [PDF]

Molecular and Cellular Biology, 1995
Bona fide apoptosis in rat and human leukemia cells, rat thymocytes, and bovine endothelial cells was accompanied by limited and specific cleavage of polysome-associated and monosome-associated 28S rRNA, with 18S rRNA being spared. Specific 28S rRNA cleavage was observed in all instances of apoptotic death accompanied by internucleosomal DNA ...
