Acute neuroinflammation induces AIS structural plasticity in a NOX2-dependent manner [PDF]
, 2017 Background Chronic microglia-mediated inflammation and oxidative stress are well-characterized underlying factors in neurodegenerative disease, whereby reactive inflammatory microglia enhance ROS production and impact neuronal integrity. Recently, it has

Selective aqueous acetylation controls the photoanomerization of α-cytidine-5′-phosphate [PDF]
, 2018 Nucleic acids are central to information transfer and replication in living systems, providing the molecular foundations of Darwinian evolution. Here we report that prebiotic acetylation of the non-natural, but prebiotically plausible, ribonucleotide α ...

Human FASTK preferentially binds single‐stranded and G‐rich RNA
The FEBS Journal, EarlyView.Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Radiopharmaceuticals for Persistent or Recurrent Uterine Cervix Cancer
Frontiers in Oncology, 2019 Uterine cervix cancers pose therapeutic challenges because of an overactive ribonucleotide reductase, which provides on-demand deoxyribonucleotides for DNA replication or for a DNA damage repair response.

Concanavalin A-Binding Enzymes of Crotalus scutulatus scutulatus Venom [PDF]
, 1985 Crotalus scutulatus scutulatus crude venom was separated into two fractions by Concanavalin A Sepharose 4B affinity chromatography. The proteins binding to Con A exhibited phosphomonoesterase (orthophosphoric monoester phosphohydrolase EC 3.1.3.2 ...

The FEBS Journal, EarlyView.Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

The FEBS Journal, EarlyView.Human SART3 has two RRM domains to engage with U6 snRNA for spliceosome recycling. This study reports solution structures of SART3 RRM domains and investigates the interaction between RRM and U6 snRNA. SART3 binds to the asymmetric bulge of U6 snRNA as a dimer via conserved positively charged surfaces.
