Better than Membranes at the Origin of Life?
Organelles without membranes are found in all types of cells and typically contain RNA and protein. RNA and protein are the constituents of ribosomes, one of the most ancient cellular structures.

Multiple prebiotic metals mediate translation. [PDF]
Today, Mg2+ is an essential cofactor with diverse structural and functional roles in life's oldest macromolecular machine, the translation system. We tested whether ancient Earth conditions (low O2, high Fe2+, and high Mn2+) can revert the ribosome to a ...

Characterization of ribosome heterogeneity during endothelial to hematopoietic transition
The panorama of ribosome heterogeneity during embryonic hematopoiesis has not yet been portrayed. In this study, utilizing dual‐omics data, the heterogenous dynamic of ribosome during endothelial‐to‐hematopoietic transition has been systemically described. Moreover, stage‐specific upregulation and peripheral localization of RPL27 and RACK1 in hemogenic

Compartmentalisation and localisation of the translation initiation factor (eIF) 4F complex in normally growing fibroblasts [PDF]
Previous observations of association of mRNAs and ribosomes with subcellular structures highlight the importance of localised translation. However, little is known regarding associations between eukaryotic translation initiation factors and cellular ...

Liver‐specific lncRNAs associated with liver cancers
Long non‐coding RNAs (lncRNAs) are regulatory molecules with various functions. They are more tissue‐specific than proteins and can be used as potential biomarkers, particularly in cancer diagnostics and prognosis. In this review, we have systematically compiled all lncRNAs with exclusive expression in the human liver, verified their liver specificity ...

Identification and characterization of yeast SNF1 kinase homologs in Leishmania major
BackgroundSucrose Non Fermenting1 (SNF1) constitutes a family of protein kinases conserved in eukaryotes, plants, and fungi. SNF1 has been known to play a crucial role in stress adaptation and metabolism, enabling organisms to respond to changing ...

Role of the Mitochondrial Genome During Early Development in Mice [PDF]
The role of the mitochondrial genome in early development and differentiation was studied in mouse embryos cultured in vitro from the two to four cell stage to the blastocyst (about 100 cells).

The Mitochondrial Myopathy, Encephalopathy, Lactic Acidosis, and Stroke-like Episode Syndrome-associated Human Mitochondrial tRNALeu(UUR) Mutation Causes Aminoacylation Deficiency and Concomitant Reduced Association of mRNA with Ribosomes [PDF]
The pathogenetic mechanism of the mitochondrial tRNALeu(UUR) A3243G transition associated with the mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome has been investigated in transmitochondrial cell lines ...
