Lactoferrin Deficiency During Lactation Causes Adult Obesity‐Related Metabolic Disease Through Persistent Adipose Dysfunction Driven by Impaired Adipocyte Development

Advanced Science, EarlyView.
Lactational lactoferrin deficiency exerts lasting effects on epididymal adipose tissue development from lactation into adulthood: it impairs adipocyte hyperplasia and induces pathological hypertrophy, resulting in lower body weight yet exacerbated metabolic dysfunction under a high‐fat diet in adulthood.

Dielectric‐Confinement‐Induced in‐Plane Photoelectric Anisotropy in Isotropic Quasi‐1D γ‐GaS Nanoribbon

Advanced Science, EarlyView.
We investigate the geometry‐governed optoelectronic anisotropy arising from dielectric confinement in quasi‐1D γ‐GaS nanoribbons with intrinsically isotropic atomic structures. Dielectric mismatch between the nanoribbon and its surroundings leads to a general polarization‐dependent photoresponse during near‐field scattering.

NAT10‐Mediated ac4C Modification of circANKRD12 Reprograms the Tumor Microenvironment

Advanced Science, EarlyView.
NAT10‐dependent acetylation of circANKRD12 drives translation of the circANKRD12_354aa protein, which binds HDAC2 to stabilize c‐Myc via deubiquitination, promoting multiple myeloma (MM) cell proliferation. Concurrently, the circANKRD12‐HDAC2 axis suppresses H3ac‐mediated transcription of IFN‐γ, TNF‐α, and GZMB in NK cells, leading to NK cell ...
