Function of Plant DExD/H-Box RNA Helicases Associated with Ribosomal RNA Biogenesis

open access: yesFrontiers in Plant Science, 2018
Ribosome biogenesis is a highly complex process that requires several cofactors, including DExD/H-box RNA helicases (RHs). RHs are a family of ATPases that rearrange the secondary structures of RNA and thus remodel ribonucleoprotein complexes. DExD/H-box

RNA folding and ribosome assembly [PDF]

open access: yesCurrent Opinion in Chemical Biology, 2008
Ribosome synthesis is a tightly regulated process that is crucial for cell survival. Chemical footprinting, mass spectrometry, and cryo-electron microscopy are revealing how these complex cellular machines are assembled. Rapid folding of the rRNA provides a platform for protein-induced assembly of the bacterial 30S ribosome.

Role of the Mitochondrial Genome During Early Development in Mice [PDF]

open access: yes, 1973
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).

Deep RNA-Seq profile reveals biodiversity, plant-microbe interactions and a large family of NBS-LRR resistance genes in walnut (Juglans regia) tissues. [PDF]

open access: yes, 2016
Deep RNA-Seq profiling, a revolutionary method used for quantifying transcriptional levels, often includes non-specific transcripts from other co-existing organisms in spite of stringent protocols. Using the recently published walnut genome sequence as a

Hypoglycemia Induces Diabetic Macrovascular Endothelial Dysfunction via Endothelial Cell PANoptosis, Macrophage Polarization, and VSMC Fibrosis

open access: yesAdvanced Science, EarlyView.
This study investigates hypoglycemia‐induced diabetic macrovascular endothelial dysfunction. It reveals that hypoglycemia triggers ZBP1‐dependent PANoptosis of endothelial cells, proinflammatory polarization of macrophages, and fibrosis of vascular smooth muscle cells (VSMCs) in diabetic mice.

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

open access: yesMitochondrial 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 ...

Studies on the relation between heme and nucleic acid syntheses in erythroid cell. 3. Nucleolus of erythroblast, changes in relation with cell specialization [PDF]

open access: yes, 1969
The disappearance of nucleolus has been traced in the rat erythroid cells in relation with the cell specialization under varying conditions, i. e. in anemia with or without treatment by bromouracil and aminopterin.

Chronic Psychological Stress Induces Cardiomyocyte Hypertrophy Through Corticosterone‐Glucocorticoid Receptor‐LAMA5 Axis

open access: yesAdvanced Science, EarlyView.
In vivo experiments suggest that cardiomyocyte hypertrophy is an early manifestation of cardiac pathological changes induced by chronic psychological stress. In vivo and in vitro experiments suggest that the corticosterone‐glucocorticoid receptor‐LAMA5 axis mediates cardiomyocyte hypertrophy induced by chronic psychological stress. The clinical results

Autophagy-dependent ribosomal RNA degradation is essential for maintaining nucleotide homeostasis during C. elegans development

open access: yeseLife, 2018
Ribosome degradation through the autophagy-lysosome pathway is crucial for cell survival during nutrient starvation, but whether it occurs under normal growth conditions and contributes to animal physiology remains unaddressed.

Probing complex RNA structures by mechanical force

open access: yes, 2003
RNA secondary structures of increasing complexity are probed combining single molecule stretching experiments and stochastic unfolding/refolding simulations. We find that force-induced unfolding pathways cannot usually be interpretated by solely invoking
