Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

High-gradient magnetic chromatography of rare-earth elements

AIP Advances
High-gradient magnetic chromatography (HGMC) is the chromatographic separation of a mixture of magnetic particles using high-gradient magnetic separation (HGMS) systems. However, unlike HGMS which has traditionally been used to separate magnetic from non-

Intein‐based modular chimeric antigen receptor platform for specific CD19/CD20 co‐targeting

Molecular Oncology, EarlyView.
CARtein is a modular CAR platform that uses split inteins to splice antigen‐recognition modules onto a universal signaling backbone, enabling precise, scarless assembly without re‐engineering signaling domains. Deployed here against CD19 and CD20 in B‐cell malignancies, the design supports flexible multi‐antigen targeting to boost T‐cell activation and

Role of Ionic Liquids in Composites in Analytical Sample Preparation

Separations, 2020
Ionic liquids (ILs) are a group of non-conventional salts with melting points below 100 °C. Apart from their negligible vapor pressure at room temperature, high thermal stability, and impressive solvation properties, ILs are characterized by their ...

Capture of Submicron Particles in Magnetized Granular Filled Beds [PDF]

Gazi Üniversitesi Fen Bilimleri Dergisi, 2020
The diffusion separation of micron and submicron sized particles was examined theoretically in the gradient magnetic field formed by tangent ferromagnetic spheres magnetized in external homogeneous magnetic field. In the gradient field around the tangent
