Acetylation Targeting Chimera (AceTAC), a novel technology is previously reported that hijacks lysine acetyltransferases p300/CBP to acetylate the p53Y220C mutant. However, p300/CBP are the only acetyltransferases harnessed for AceTAC development to date.

Bright NIR-II emissive cyanine dye-loaded lipoprotein-mimicking nanoparticles for fluorescence imaging-guided and targeted NIR-II photothermal therapy of subcutaneous glioblastoma.

Cyanine dye-containing nanoparticles have widely been used in "all-in-one" NIR fluorescence imaging (FI)-guided photothermal therapy (PTT) because of their intrinsically large extinction coefficient and available physical and chemical modulation methods to tune absorption and emission wavelengths. The combination of good brightness and excellent tumor-targeting capacity is the key to realize efficient NIR-II FI-guided PTT. In this study, by covalently decorating NIR-II absorptive cyanine dyes with bulky AIE motify, we demonstrate how steric hindrance suppresses π-π stacking-induced fluorescence quenching and contributes to the good brightness of NIR-II FI of subcutaneous glioblastoma.

Biogeographic patterns of viral communities, ARG profiles and virus-ARG associations in adjacent paddy and upland soils across black soil region.

Biogeographic distribution of prokaryotic and eukaryotic communities has been extensively studied. Yet, our knowledge of viral biogeographic patterns, the corresponding driving factors and the virus-resistome associations is still limited. Here, using metagenomic analysis, we explored the viral communities and profiles of antibiotic resistance genes (ARGs) in 30 fields of paddy (rice soils, RS) and upland soils (corn soils, CS) at a regional scale across black soil region of Northeast China.

Molecular Basis of Lipid Metabolism in L.

Lipids are the basic biological molecules in plants, serving as glycerolipids for cell membranes and triacylglycerols as an energy source. Fatty acids are the major components of plant lipids. Both lipids and fatty acids significantly influence rice quality.

Biocompatible DNA hydrogel composed of minimized Takumi-shaped DNA nanostructure exhibits sustained retention after in vivo administration.

Our previous studies showed that DNA hydrogels containing unmethylated CpG motifs effectively induced antigen-specific immune responses when combined with the appropriate antigens. A potential drawback of existing DNA hydrogels for further applications is the need for many oligodeoxynucleotide (ODN) types. Therefore, in this study, we attempted to optimize and minimize the nanostructured DNA units for DNA hydrogels to reduce the preparation cost, design difficulty, and possible risk of sequence-dependent off-target effects, and prepare DNA hydrogels with sustained retention ability.

A Chiral COFs Membrane for Enantioselective Amino Acid Separation.

Incorporating chiral molecules in the covalent organic frameworks (COFs) with uniformly ordered pores results in chiral COFs, which have been highly promising candidates for enantioseparation. Herein, a homochiral COF nanochannel membrane is reported by introducing chiral centers (L-phenylalanine methyl ester) into one of the organic ligands for the enantioseparation of chiral amino acids. The separation results show that the D-isomer is preferentially transported through the porous membrane channel.

A PROTAC degrader suppresses oncogenic functions of PTK6 inducing apoptosis of breast cancer cells.

Protein tyrosine kinase 6 (PTK6), a non-receptor tyrosine kinase, is an oncogenic driver in many tumor types. However, agents that therapeutically target PTK6 are lacking. Although several PTK6 kinase inhibitors have been developed, none have been clinically translated, which may be due to kinase-independent functions that compromise their efficacy.

Targeted Degradation of Receptor-Interacting Protein Kinase 1 to Modulate the Necroptosis Pathway.

Necroptosis is a highly regulated form of necrotic cell death that plays an essential role in pathogen defense and tissue homeostasis. Abnormal regulation of the necroptotic pathway has been implicated in the pathogenesis of various human diseases, including cancer, inflammatory, and neurodegenerative diseases. Receptor-interacting protein kinase 1 (RIPK1) serves as a crucial regulator of the necroptotic signaling pathway and has been identified as a potential therapeutic target.

Treatment of minimal residual disease in myeloid malignancies after allo-HSCT with venetoclax-based regimens in patients ineligible for or failed in the immunotherapy.

Background: Relapse was the major cause of treatment failure in patients with myeloid malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Patients who still suffer from the disease while cannot be detected by morphological analysis can be identified by the minimal residual disease (MRD) monitoring. The most used first-line regimens for MRD are immunotherapies.
