Ribosomal protein paralogues in ribosome specialization

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences
Ribosomes are macromolecular complexes responsible for protein synthesis, comprising ribosomal proteins (RPs) and ribosomal RNA. While most RPs are present as single copies in higher eukaryotes, a handful of them have paralogues that emerged through duplication events.

Interstitium‐Mimicking Porous Alveolar Membranes Enable Physiologic Aerosol Transport and Distinct Acute‐Chronic Lung Injury Responses

open access: yesAdvanced Functional Materials, EarlyView.
An interstitium‐mimicking membrane combines three‐dimensional alveolar geometry, high pore interconnectivity, and mechanical compliance to overcome transport limitations of conventional lung‐on‐chip barriers. The resulting platform supports physiologic aerosol transport, quantitative analysis of cross‐barrier particle movement, and reveals divergent ...

A 'garbage can' for ribosomes: how eukaryotes degrade their ribosomes.

open access: yes, 2010
Ribosome synthesis is a major metabolic activity that involves hundreds of individual reactions, each of which is error-prone. Ribosomal insults occur in cis (alteration in rRNA sequences) and in trans (failure to bind to, or loss of, an assembly factor ...

Malectin Alleviates Endoplasmic Reticulum Stress in Gestational Diabetes Mellitus via Glycoprotein Quality Control Mechanisms

open access: yesAdvanced Science, EarlyView.
Malectin alleviates high glucose‐induced ER stress and damage in placental trophoblasts, a function dependent on its six critical carbohydrate‐binding residues. In a GDM mouse model, administration of TAT‐Malectin ameliorated hyperglycemia and placental ER stress and prevented fetal macrosomia.

Using Ribosomes to Create Other Polymers

open access: yes, 2021
For my presentation, I am studying the use of ribosomes in the synthesis of polymers. Ribosomes are organelles that exist within living cells. Their purpose is to read messenger RNA and then form proteins based on the instructions encoded within the RNA.

Mitochondrial heat shock protein 70, a molecular chaperone for proteins encoded by mitochondrial DNA [PDF]

open access: yes, 1994
Mitochondrial heat shock protein 70 (mt-Hsp70) has been shown to play an important role in facilitating import into, as well as folding and assembly of nuclear-encoded proteins in the mitochondrial matrix.

The Arabidopsis cytosolic ribosomal proteome: from form to function

open access: yesFrontiers in Plant Science, 2013
The cytosolic ribosomal proteome of Arabidopsis thaliana has been studied intensively by a range of proteomics approaches and is now one of the best-characterised eukaryotic ribosomal proteomes.

TRMT6‐Mediated m1A Modification of CDK9 mRNA Is a Dual‐Pronged Pathogenic Driver for HBV‐Related Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
TRMT6‐mediated m1A modification in CDK9 mRNA enhances its mRNA stability and translation efficiency, thereby increasing the protein levels of CDK9. Upregulated CDK9 promotes the progression of HCC by elevating the levels of oncogenic factors including p‐STAT3, MCL1, and BCL‐2. On the other hand, CDK9 phosphorylates TARDBP at Ser254 to activate HBV core

Dom34 Rescues Ribosomes in 3′ Untranslated Regions

open access: yes, 2014
SummaryRibosomes that stall before completing peptide synthesis must be recycled and returned to the cytoplasmic pool. The protein Dom34 and cofactors Hbs1 and Rli1 can dissociate stalled ribosomes in vitro, but the identity of targets in the cell is ...

Accelerating cancer without mutations

open access: yeseLife, 2019
Mice get melanoma faster when they have common, inherited variants in a few genes that control cell-wide changes but also respond to the environment.
