A System of RNA Modifications and Biased Codon Use Controls Cellular Stress Response at the Level of Translation [PDF]
Cells respond to environmental stressors and xenobiotic exposures using regulatory networks to control gene expression, and there is an emerging appreciation for the role of numerous postsynthetic chemical modifications of DNA, RNA, and proteins in ...

COP9 signalosome subunit 6 (CSN6) promotes the auto‐ubiquitination and degradation of DDB1‐CUL4 associated factor 1 (DCAF1), thereby antagonizing DCAF1‐mediated ubiquitination of Nucleophosmin (NPM1). This stabilization of NPM1 enhances the ribosome biogenesis process and the translation of specific gemcitabine‐resistance proteins, ultimately driving ...

Metabolism‐Regulating Nanomedicines for Cancer Therapy
This review highlights metabolism‐regulating nanomedicines designed to target glycolytic, lipid, amino acid, and nucleotide pathways in tumors. By incorporating metabolism‐regulating agents into versatile nanocarriers such as liposomes, micelles, dendrimers, and engineered bacteria, these platforms achieve targeted delivery, controlled release ...

Nitrogen-Centered Radicals Derived from Azidonucleosides
Azido-modified nucleosides have been extensively explored as substrates for click chemistry and the metabolic labeling of DNA and RNA. These compounds are also of interest as precursors for further synthetic elaboration and as therapeutic agents.

Regulation of ribonucleotide reductase by Spd1 involves multiple mechanisms [PDF]
The correct levels of deoxyribonucleotide triphosphates and their relative abundance are important to maintain genomic integrity. Ribonucleotide reductase (RNR) regulation is complex and multifaceted.

QM/MM modeling of Sulerythrin (SulE) identifies three electronic states of its diiron center, differing in protonation and bridging ligands. The results reconcile crystallographic heterogeneity and reveal how subtle electronic and structural changes govern non‐heme diiron enzyme reactivity.

Characterisation of gene expression profiles of yeast cells expressing BRCA1 missense variants [PDF]
Germline mutations in breast cancer susceptibility gene 1 (BRCA1) confer high risk of developing breast and ovarian cancers. Even though most BRCA1 cancer-predisposing mutations produce a non-functional truncated protein, 5-10% of them cause single amino
