Targeting KPNB1 suppresses AML cells by inhibiting HMGB2 nuclear import.

Acute myeloid leukemia (AML) represents the most prevalent malignancy within the hematologic system, characterized by refractory relapses and a scarcity of effective treatment options. Karyopherin subunit beta-1 (KPNB1) is a member of karyopherin β family, mediating the nuclear import of its cargoes. In this study, we found that elevated expression levels of KPNB1 are associated with unfavorable outcomes in patients with AML.

Effects of orelabrutinib, a BTK inhibitor, on antibody-mediated platelet destruction in primary immune thrombocytopenia.

Primary immune thrombocytopenia (ITP) is a haemorrhagic disorder with a complex pathogenesis, wherein autoreactive B-cell-mediated platelet destruction plays a crucial role. Bruton's tyrosine kinase (BTK) is widely expressed and essential for immune cells. Several BTK inhibitors have been used clinically to treat haematological malignancies, while few studies are focusing on the regulatory role of BTK in ITP.

Interleukin-16 enhances anti-tumor immune responses by establishing a Th1 cell-macrophage crosstalk through reprogramming glutamine metabolism in mice.

Overcoming immunosuppression in the tumor microenvironment (TME) is crucial for developing novel cancer immunotherapies. Here, we report that IL-16 administration enhances the polarization of T helper 1 (Th1) cells by inhibiting glutamine catabolism through the downregulation of glutaminase in CD4 T cells and increases the production of Th1 effector cytokine IFN-γ, thus improving anti-tumor immune responses. Moreover, we find that establishing an IL-16-dependent, Th1-dominant TME relies on mast cell-produced histamine and results in the increased expression of the CXCR3 ligands in tumor-associated macrophages (TAM), thereby improving the therapeutic effectiveness of immune checkpoint blockade (ICB).

Search for MeV-Scale Axionlike Particles and Dark Photons with PandaX-4T.

Axionlike particles (ALPs) and dark photons (DPs) are viable dark matter particle candidates. We have searched for possible ALP/DP signals in the PandaX-4T liquid xenon detector using 440  kg·yr of data.

Graphene-polymer reinforcement of perovskite lattices for durable solar cells.

The lattice deformation and structural evolution of perovskite films in response to electric fields, temperature, and light limit the operational endurance of solar cells. We mechanically reinforced perovskite thin films by integrating a polymer-coupled monolithic single-layer graphene interface that led to a twofold enhancement in modulus and hardness. The synergistic effect of graphene and poly(methyl methacrylate) restricted photoinduced lattice expansion and decreased the deformation ratio from 0.

Inhibiting Overoxidation of Dynamically Evolved RuO to Achieve a Win-Win in Activity-Stability for Acidic Water Electrolysis.

Proton exchange membrane (PEM) water electrolysis offers an efficient route to large-scale green hydrogen production, in which the RuO catalyst exhibits superior activity but limited stability. Unveiling the atomic-scale structural evolution during operando reaction conditions is critical but remains a grand challenge for enhancing the durability of the RuO catalyst in the acidic oxygen evolution reaction (a-OER). This study proposes an adaptive machine learning workflow to elucidate the potential-dependent state-to-state global evolution of the RuO(110) surface within a complex composition and configuration space, revealing the correlation between structural patterns and stability.

Narrow Bandgap Perovskite Enabled by Heterovalent Co-Doping for Visible-NIR Light Photocatalytic CO Reduction.

Metal halide perovskites have garnered significant attention due to their vast potential in various optoelectronic applications. While their tunable bandgap properties allow for light absorption across the ultraviolet and much of the visible spectrum, the coverage in the near-infrared (NIR) region remains limited. Here, we demonstrate a heterovalent co-doping method for synthesizing Ag and Bi doped CsSnBr crystals with absorption edge up to 1300 nm, making it one of the narrowest bandgap perovskite materials.

The data processing is improved compared to previous work, unifying the low-level signal reconstruction in a wide energy range up to 120 keV.

Inhibition of DEK restores hematopoietic stem cell function in Fanconi anemia.

Hematopoietic stem cells (HSCs) are susceptible to replication stress, which is a major contributor to HSC defects in Fanconi anemia (FA). Here, we report that HSCs relax the global chromatin by downregulating the expression of a chromatin architectural protein, DEK, in response to replication stress. DEK is abnormally accumulated in bone marrow (BM) CD34+ cells from patients with FA and in Fancd2-deficient HSCs.

Microenvironment-responsive injectable hydrogel for neuro-vascularized bone regeneration.

Bone is a richly innervated and vascularized tissue, whereas nerve-vascular network reconstruction was often ignored in biomaterial design, resulting in delayed or incomplete bone healing. Inspired by the bone injury microenvironments, here we report a controllable drug delivery strategy using a pH and reactive oxygen species (ROS) dual-response injectable hydrogel. Based on the dynamic borate ester bond covalent crosslinking, nano-hydroxyapatite (HA) and curculigoside (CCG) are integrated into PVA/TSPBA (PT) to construct a responsive injectable hydrogel (PTHC), which scavenges excessive ROS from the injury microenvironment and responsively releases HA and CCG, providing favorable homeostasis and sustained release drug delivery system for bone repair.
