Molnupiravir Protects Mice from Bourbon Virus Disease
2026-09-17
Bamunuarachchi and colleagues show that molnupiravir inhibits Bourbon virus replication and disease in a susceptible mouse model. Protection included improved survival, lower tissue viral burden, less thrombocytopenia, and reduced liver and spleen pathology, including when treatment began 24 or 48 hours after infection.

SCP4 and H3T3 Dephosphorylation in Mitosis
2026-09-15
The reference study identifies SCP4 as a nuclear phosphatase that counterbalances Haspin-dependent phosphorylation of histone H3 at threonine 3 during mitosis. Its findings connect SCP4 activity with chromosomal passenger complex recruitment, faithful chromosome segregation, and prevention of aneuploidy in cells and early embryos.

2-Thio-dCTP for DNA Assay Design
2026-09-15
2-Thio-dCTP enables controlled DNA polymerase selectivity tests, enzymatic nucleotide incorporation, and sulfur-marked DNA substrates for interaction studies. This workflow-focused guide shows how to connect those assays to mechanistic questions raised by SCP4-dependent chromosome regulation without overstating what a modified-DNA experiment can prove.

SCP4, H3T3 Dephosphorylation, and Chromosome Stability
2026-09-14
The reference study identifies SCP4 as a nuclear phosphatase that counterbalances Haspin-dependent H3T3 phosphorylation during mitosis. By linking SCP4 activity to chromosomal passenger complex recruitment, chromosome segregation, aneuploidy, and early embryonic division, the work defines a previously unresolved layer of mitotic quality control.

Commensal Sugar, IL-22, and Obesity Protection
2026-09-14
A recent bioRxiv preprint identifies a phosphocholine-modified exopolysaccharide from the human commensal Clostridium immunis as a microbiota-derived regulator of obesity. Through bacterial genetics, purified-molecule studies, host immunometabolic phenotyping, and human metagenomic analysis, the work connects the licABC pathway to visceral fat, beige-cell recruitment, and energy expenditure.

Early Pheromone Sensing and Neurodegeneration in C. elegans
2026-09-13
Peng et al. show that pheromone exposure during early C. elegans development can reprogram neuronal signaling and accelerate neurodegeneration later in life. The study identifies a mechanistic route from ASK and ASI chemosensory neurons through AIA interneurons, insulin-like signaling, and reduced neuronal autophagy, providing a framework for studying how environmental cues influence proteostasis.

Cholesterol Hinders LNP Intracellular Trafficking
2026-09-12
Luo and colleagues developed an imaging-based platform to distinguish nucleic acid uptake, endosomal trafficking, and delivery-relevant localization in lipid nanoparticles. Their results indicate that increasing cholesterol, rather than increasing the N/P ratio alone, promotes peripheral early-endosome accumulation and restricts LNP–nucleic acid progression toward release-competent compartments.

iRGD-RBCM Nanocarriers Improve Neuroblastoma PDT
2026-09-11
Wu and colleagues developed iRGD-functionalized red blood cell membrane vesicles to deliver the photosensitizer TPOR for neuroblastoma photodynamic therapy. The study shows that combining biomimetic circulation properties with tumor-penetrating functionality can improve cellular uptake, apoptosis, migration suppression, and tumor growth control compared with free TPOR.
