Homocysteine Exacerbates Pulmonary Fibrosis via Orchestrating Syntaxin 17 Homocysteinylation of Alveolar Type II Cells

Advanced Science, EarlyView.
The study identifies elevated homocysteine (Hcy) levels in idiopathic pulmonary fibrosis patients' samples, with alveolar type 2 cells as the primary site of Hcy metabolism. Methionine synthase reductase downregulation in these cells exacerbates fibrosis, while folate administration reduces Hcy levels and alleviates fibrosis.

Hsa_circ_0026782 Acts as a “Molecular Break” of CREB1‐Mediated Transcription by Promoting Its Phosphorylation at Ser142 That Prevents Keloid Progression

Advanced Science, EarlyView.
Model for the role of hsa_circ_0026782/p‐CREB1 (Ser142) played in keloid. Hsa_circ_0026782 is derived from back‐splicing of ITGA7 exon 4. When hsa_circ_0026782 binds to CREB1, the exposure of the bZIP domain and dimerization of CREB1 are promoted (upper left).

Post-translational modification of PII signal transduction proteins

Frontiers in Microbiology, 2015
The PII proteins constitute one of the most widely distributed families of signal transduction proteins in nature. They are pivotal players in the control of nitrogen metabolism in bacteria and archaea, and are also found in the plastids of plants. Quite

A Porcine Monoclonal Antibody Targeting a Conserved GP4 Epitope Protects against In Vivo Infection via the Induction of Broad‐Spectrum PRRSV Neutralization

Advanced Science, EarlyView.
This study developed mAb‐5F2, a monoclonal antibody targeting conserved GP4 residues (Q48/I50), which blocks the GP4‐CD163 interaction, resulting in a 78–85% reduction in viral entry. Porcineized 5F2‐pFc prevented mortality in infected piglets, reduced pulmonary viral loads, and minimized lesions. This broad‐spectrum antibody platform overcomes vaccine

Posttranslational microtubule modification alters podocalyxin-trafficking in epithelial cells

Frontiers in Cell and Developmental Biology
Epithelial polarization is characterized by separation of the plasma membrane into an apical and a basolateral membrane domain. This morphology is verified by cytoskeletal organization that stabilizes the cellular architecture and provides specific ...

Studying Posttranslational Modifications by In-Cell NMR

Chemistry & Biology, 2008
Functional in vivo investigation of posttranslational modifications is a problem that a number of analytical techniques are trying to tackle. Below, we briefly discuss the breakthroughs and challenges in placing NMR spectroscopy on the map, as illustrated by a recent report by Selenko et al. (2008).

Lactate Metabolic Reprogramming Mediated by CircRNA–LDHA Complex Facilitates Innate Immune Evasion of Liver Cancer

Advanced Science, EarlyView.
CircSMPD4 physically combines with lactate dehydrogenase A (LDHA) and reduces its acetylation level via SIRT2‐dependent deacetylation, thereby inhibiting chaperone‐mediated autophagy‐lysosome degradation of LDHA. Upregulating LDHA leads to increasing lactate production and extracellular export, which in turn suppresses natural killer cell cytotoxicity ...

High‐Throughput Engineering and Modification of Non‐Ribosomal Peptide Synthetases Based on Golden Gate Assembly

Angewandte Chemie, EarlyView.
A Golden Gate Assembly (GGA)‐based method was developed for the efficient assembly of natural and engineered non‐ribosomal peptide synthetases (NRPS). This method has enabled the creation of NRPS libraries to generate novel peptides in high‐throughput as well as the targeted derivatisation of natural products (NPs).
