Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.

NoRC, a novel chromatin remodeling complex involved in ribosomal RNA gene silencing [PDF]

, 2004
Regulation of gene expression takes place in the nucleus in a highly structured and condensed nucleoprotein environment, called chromatin (Felsenfeld and Groudine, 2003; Khorasanizadeh, 2004; Vaquero et al., 2003).

Intergeneric transfer of ribosomal genes between two fungi

BMC Evolutionary Biology, 2008
Background Horizontal gene transfer, also called lateral gene transfer, frequently occurs among prokaryotic organisms, and is considered an important force in their evolution.

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

Advanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Gene expression regulation of ribosomal protein genes

, 2016
Saccharomyces cerevisiae cells produce 2000 ribosomes per minute under normal conditions. The expression of ribosomal proteins is massive - it takes 50% of RNA polymerase II transcription and 90% of pre-mRNA splicing in rapidly growing cells. Since cells

Nuclear Photosynthetic Gene Expression Is Synergistically Modulated by Rates of Protein Synthesis in Chloroplasts and Mitochondria [PDF]

, 2006
Arabidopsis thaliana mutants prors1-1 and -2 were identified on the basis of a decrease in effective photosystem II quantum yield. Mutations were localized to the 5'-untranslated region of the nuclear gene PROLYL-tRNA SYNTHETASE1 (PRORS1), which acts in ...

The control of ribosomal RNA synthesis in mammalian cells

, 2013
The biogenesis of ribosomes is a fundamental process that occurs in all living cells. In mammalian cells, it is a highly complex process consisting of the coordinated synthesis and assembly of four ribosomal RNAs (rRNAs) with about 80 ribosomal proteins (

Characterisation of the genes for ribosomal RNA in flax

Nucleic Acids Research, 1981
DNA coding for the 18S and 25S rRNAs in flax (Linum usitatissimum) has been purified and is arranged in tandem arrays with a repeat length of 8.6 kb. There is no detectable variation in the size of this repeat unit. Single repeat units have been cloned in the plasmid pAT 153.
