Evidence for compensatory evolution of ribosomal proteins in response to rapid divergence of mitochondrial rRNA.

Molecular biology and evolution, 2012
Rapid evolution of mitochondrial DNA (mtDNA) places intrinsic selective pressures on many nuclear genes involved in mitochondrial functions. Mitochondrial ribosomes, for example, are composed of mtDNA-encoded ribosomal RNAs (rRNAs) and a set of more than

α‐Synuclein Pathology Spreads in a Midbrain–Hindbrain Assembloid Model

Advanced Science, EarlyView.
A novel midbrain–hindbrain assembloid model demonstrates the spread of α‐synuclein pathology, a hallmark of Parkinson's disease, mimicking Braak's hypothesis. This model reveals how pathology propagates from the hindbrain to the midbrain, inducing synaptic changes and early signs of neuronal vulnerability. It offers an innovative platform for exploring

Dynamics of Cell Fate Decisions during Chemically Induced Multi‐Lineage Trans‐Differentiation at Single‐Cell Level

Advanced Science, EarlyView.
A critical aspect of chromosomal remodeling in small molecule‐induced multilineage trans‐differentiation(iMT) is elucidated. A dynamic atlas spanning over 35 days profiles terminal trans‐differentiated cells, which reverted to a more youthful state. This study reveals parallels between iMT and other cell fate determination processes, emphasizing an ...

Promiscuous behaviour of archaeal ribosomal proteins: Implications for eukaryotic ribosome evolution

Nucleic Acids Research, 2012
In all living cells, protein synthesis occurs on ribonucleoprotein particles called ribosomes. Molecular models have been reported for complete bacterial 70S and eukaryotic 80S ribosomes; however, only molecular models of large 50S subunits have been ...

Orally Administered Functional Polyphenol‐Nanozyme‐Armored Probiotics for Enhanced Amelioration of Intestinal Inflammation and Microbiota Dysbiosis

Advanced Science, EarlyView.
This study presents a novel polyphenol‐nanozyme‐armored probiotic system (ECA@EcN) for enhanced treatment of inflammatory bowel disease (IBD). By integrating chitosan‐modified epigallocatechin gallate (EGCG‐CS) with gold nanozymes, the system effectively scavenges ROS, improves probiotic viability, and restores gut microbiota balance.

Structure Elucidation, Total Synthesis, Antibacterial In Vivo Efficacy and Biosynthesis Proposal of Myxobacterial Corramycin**

Angewandte Chemie International Edition, Volume 61, Issue 51, December 19, 2022., 2022
Corramycin is a novel natural product produced by the myxobacterium Corallococcus coralloides. The structure, extraordinary total synthesis and biosynthesis of the antibiotic is described for the first time. Its promise as an in vivo septicemia model, the absence of cross‐resistance with commonly used antibiotic classes, and the lack of cytotoxicity ...

Scission of the p53-MDM2 Loop by Ribosomal Proteins.

Genes & cancer, 2012
The oncoprotein MDM2 is both the transcriptional target and the predominant antagonist of the tumor suppressor p53. MDM2 inhibits the functions of p53 via a negative feedback loop that can be circumvented by several ribosomal proteins in response to ...

Screening and Identification of Novel DNA Aptamer for Targeted Delivery to Injured Podocytes in Glomerular Diseases

Advanced Science, EarlyView.
This study develops RLS‐2, a high‐affinity aptamer that specifically targets injured podocytes, making it a promising candidate for targeted drug delivery. In vitro, RLS‐2 shows stability, specificity, efficient siRNA delivery via AsiCs, and uptake by podocytes.

Ribosomal proteins L7 and L8 function in concert with six A₃ assembly factors to propagate assembly of domains I and II of 25S rRNA in yeast 60S ribosomal subunits.

RNA: A publication of the RNA Society, 2012
Ribosome biogenesis is a complex multistep process that involves alternating steps of folding and processing of pre-rRNAs in concert with assembly of ribosomal proteins.
