The genomes of two key bumblebee species with primitive eusocial organization [PDF]

open access: yes, 2015
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.

ERM Inhibition Confers Ferroptosis Resistance through ROS‐Induced NRF2 Signaling

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
ERM inhibition disrupts ERM‐actin interactions, elevating ROS and triggering KEAP1 degradation, which stabilizes and activates NRF2. Nuclear NRF2 induces cytoprotective genes, notably HMOX1, enhancing redox buffering and suppressing lipid peroxidation to resist erastin‐induced ferroptosis.

Spatially Resolved Multiomics Reveals Metabolic Remodeling and Autophagy Activation in Adamantinomatous Craniopharyngiomas

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
Multiomics integration analysis reveals the “cystic fluid–tumor cell” metabolic coupling that mediates active choline/ethanolamine uptake of tumor cells from cystic fluid and PC/PE synthesis pathways reprogramming that mediating autophagy pathway activation within ACP. ABSTRACT Adamantinomatous craniopharyngioma (ACP), a benign yet highly recurrent and

Next‐Generation Antioxidant Strategies: From Nanoformulations to Gene‐Targeted Therapies

open access: yescScience, Volume 2, Issue 1, March 2026.
ABSTRACT Antioxidants play a pivotal role in neutralizing oxidative stress, a key factor in aging and chronic diseases such as cancer, cardiovascular disorders, and neurodegeneration. Although traditional antioxidants such as vitamins C and E, polyphenols, and endogenous enzymes have shown efficacy in laboratory and clinical studies, their therapeutic ...

Selenoprotein P gene r25191g/a polymorphism and quantification of selenoprotein P mRNA level in patients with Kashin-Beck disease [PDF]

open access: yesBritish Journal of Nutrition, 2010
Kashin-Beck disease (KBD) is an endemic and deformable osteoarthrosis. Epidemiological study has revealed that lower Se level is the principal environmental factor in the pathogenesis of KBD. Selenoprotein P (SEPP1) is a special selenoprotein, which is the primary form of Se in vivo.

A Hybrid Nanosystem for Prostate Cancer Therapy: Codelivery of Enzalutamide and Curcumin via Selenium‐Embedded Mesoporous Silica and Chitosan Nanoparticles

open access: yesChemistryOpen, Volume 15, Issue 3, March 2026.
Herein, solvent extraction was selected for cetyltrimethylammonium bromide removal and the development of optimized Se‐embedded mesoporous silica nanoparticles, which were loaded with enzalutamide. Additionally, to improve the anticancer activity of Se@MSNPs‐Enz and curcumin bioavailability, curcumin‐loaded chitosan nanoparticles were prepared. This pH‐
