A Self-Assembled Nano-Molecular Glue (Nano-mGlu) Enables GSH/HO-Triggered Targeted Protein Degradation in Cancer Therapy.

Molecular glues are promising protein-degrading agents that hold great therapeutic potential but face significant challenges in rational design, effective synthesis, and precise targeting of tumor sites. In this study, we first overcame some of these limitations by introducing a fumarate-based molecular glue handle onto specific ligands of therapeutic kinases (TBK1, FGFR, and Bcr-Abl), resulting in the effective degradation of these important cancer targets. Despite the broad applicability of the strategy, we unexpectedly discovered potent and widespread cytotoxicity across various cell lines, including noncancerous ones, rendering it less effective in cancer therapy.

Microwave-Field-Optimized GO/TiO Nanomaterials for Enhanced Interfacial Charge Transfer in Photocatalysis.

The swift recombination of photo-induced electrons and holes is a major obstacle to the catalytic efficiency of TiO nanomaterials, but the incorporation of graphene oxide and out-field modification is considered a potent method to augment photocatalytic properties. In this work, a series of GO/TiO photocatalysts were successfully optimized by a microwave field. As determined by transient photocurrent response and electrochemical impedance spectroscopy (EIS) tests, microwave irradiation at 600 W for 5 min on the GO/TiO photocatalyst promoted interfacial charge transfer and suppressed charge recombination.

Turing covalent organic framework membranes via heterogeneous nucleation synthesis for organic solvent nanofiltration.

Although covalent organic frameworks (COFs) demonstrate notable potential for developing advanced separation membranes, contemporary COF membranes still lack controlled stacking and highly efficient sieving. Here, Turing-architecture COF membranes were constructed by engineering a reaction-diffusion assembly process via heterogeneous nucleation synthesis with tannic acid (TA). TA covalently binds with amine monomers to form a composite precursor with increased reactivity and decreased diffusivity.

Bone marrow stromal cells protect myeloma cells from ferroptosis through GPX4 deSUMOylation.

Bone marrow stromal cells (BMSCs) are vital for preventing chemotherapy induced apoptosis of multiple myeloma (MM), but roles and machinery in other forms of cell death have not been well elucidated. Here, using an in vitro BMSC-MM interacting model, we observed BMSCs protected MM cells from labile iron pool (LIP) and reactive oxygen species (ROS) triggered ferroptosis by elevating glutathione peroxidase 4 (GPX4). Mechanistically, direct interaction with BMSCs upregulated the expression of SUMO-specific protease 3 (SENP3) in MM cells through CD40/CD40L signaling pathway, and SENP3 de-conjugated SUMO2 at lysine 75 residue to stabilize GPX4 protein, thereby consuming ROS to obviate ferroptosis in MM cells from the Vk∗MYC mouse model, as well as in CD138B220 cells separated from the Cd40l;Prx1 mice (CD40-CKO) and Sumo2 knock out (SUMO2-KO) mice.

Magnetic resonance elastography in a nutshell: Tomographic imaging of soft tissue viscoelasticity for detecting and staging disease with a focus on inflammation.

Magnetic resonance elastography (MRE) is an emerging clinical imaging modality for characterizing the viscoelastic properties of soft biological tissues. MRE shows great promise in the noninvasive diagnosis of various diseases, especially those associated with soft tissue changes involving the extracellular matrix, cell density, or fluid turnover including altered blood perfusion - all hallmarks of inflammation from early events to cancer development. This review covers the fundamental principles of measuring tissue viscoelasticity by MRE, which are based on the stimulation and encoding of shear waves and their conversion into parameter maps of mechanical properties by inverse problem solutions of the wave equation.
