Disruption of the eEF1A1/ARID3A/PKC‐δ Complex by Neferine Inhibits Macrophage Glycolytic Reprogramming in Atherosclerosis

open access: yesAdvanced Science, EarlyView.
The eEF1A1/ARID3A/PKC‐δ complex critically regulates macrophage glycolytic reprogramming in atherosclerosis by mediating ARID3A phosphorylation and nuclear translocation, thereby driving ENO2 transcriptional activation. Neferine targets eEF1A1 to disrupt the eEF1A1/ARID3A/PKC‐δ complex to inhibit ENO2‐mediated macrophage glycolytic reprogramming in ...

Destabilization of mutated human PUS3 protein causes intellectual disability

open access: yesHuman Mutation, Volume 43, Issue 12, Page 2063-2078, December 2022., 2022
The homodimer of pseudouridine synthase 3 converts uridines at position 39 in tRNAs to pseudouridine (ψ), which affects tRNA stability and regulates RNA–protein interactions. Several patient‐derived variants of PUS3 have been associated with neurodegenerative diseases.

Extracellular tyrosyl‐tRNA synthetase cleaved by plasma proteinases and stored in platelet α‐granules: Potential role in monocyte activation

open access: yesResearch and Practice in Thrombosis and Haemostasis, 2020
Background Tyrosyl‐tRNA synthetase (YRS) belongs to the family of enzymes that catalyzes the tRNA aminoacylation reaction for protein synthesis, and it has been recently shown to exert noncanonical functions.

A eubacterial origin for the human tRNA nucleotidyltransferase? [PDF]

open access: yes, 2001
tRNA CCA-termini are generated and maintained by tRNA nucleotidyltransferases. Together with poly(A) polymerases and other enzymes they belong to the nucleotidyltransferase superfamily.

Halofuginone Disrupted Collagen Deposition via mTOR‐eIF2α‐ATF4 Axis to Enhance Chemosensitivity in Ovarian Cancer

open access: yesAdvanced Science, EarlyView.
COL1A1, a major component of ECM, contributes to chemoresistance and poor prognosis in ovarian cancer. Halofuginone (HF) attenuates CAF‐secreted COL1A1 through mTOR‐eIF2α‐ATF4 axis. Notably, HF disrupts collagen deposition to form the looser ECM and facilitates CD8+ T cell infiltration, partially via M2‐M1 macrophage polarization to enhance ...

Functional characterization of a novel TP53RK mutation identified in a family with Galloway–Mowat syndrome

open access: yesHuman Mutation, Volume 43, Issue 12, Page 1866-1871, December 2022., 2022
Abstract Galloway–Mowat syndrome (GAMOS) is a very rare condition characterized by early‐onset nephrotic syndrome and microcephaly with variable neurologic features. While considerable genetic heterogeneity of GAMOS has been identified, the majority of cases are caused by pathogenic variants in genes encoding the four components of the Kinase ...

Physicochemical analysis of rotavirus segment 11 supports a 'modified panhandle' structure and not the predicted alternative tRNA-like structure (TRLS) [PDF]

open access: yes, 2013
.Rotaviruses are a major cause of acute gastroenteritis, which is often fatal in infants. The viral genome consists of 11 double-stranded RNA segments, but little is known about their cis-acting sequences and structural elements.

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

open access: yesAdvanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

The Exosome Subunit Rrp44 Plays a Direct Role in RNA Substrate Recognition [PDF]

open access: yes, 2007
The exosome plays key roles in RNA maturation and surveillance, but it is unclear how target RNAs are identified. We report the functional characterization of the yeast exosome component Rrp44, a member of the RNase II family.

ALKBH3‐Mediated M1A Demethylation of METTL3 Endows Pathological Fibrosis:Interplay Between M1A and M6A RNA Methylation

open access: yesAdvanced Science, EarlyView.
RNA modification is crucial in fibrosis diseases, but the role of m1A modification remains elusive. This study reveals that ALKBH3, an m1A demethylase, drives skin fibrosis by reshaping m6A RNA modification and stabilizing COL1A1 and FN1 mRNAs through METTL3, uncovering a crosstalk between m1A and m6A methylation in pathological events.
