Summary: Glioblastoma (GBM) is a primary brain tumor with poor prognosis. Tumor recurrence and resistance to chemotherapy are the main challenges. This study evaluated the potential of using elastin-like polypeptide (ELP) hydrogels as a local drug delivery system for GBM treatment. Results showed that ELP hydrogels can be engineered to release anti-cancer drugs over time, significantly reducing GBM cell survival and proliferation in vitro. These findings highlight the potential of ELP hydrogels for improving prognosis in GBM patients after tumor resection.

Summary: Rod-shaped nanoparticles made of C-S-B triblock polypeptides show efficient delivery of siRNA into cells, leading to gene knockdown and apoptosis. However, their lower effectiveness in inducing cell death compared to cationic lipid-based formulations is attributed to high lysosome co-localization, which requires future optimization. Overall, non-toxic C-S-B nanoparticles warrant further development as a new siRNA delivery system for cancer therapy.

Summary: In this study, dumbbell-like linear-dendritic copolymers based on polyethylene glycols with aspartic dendrons were synthesized. The ionic complexes of these oppositely charged copolymers exhibited self-assembly in water and methanol and formed gels in low polar solvents. Various characterization techniques indicated a lamellar structure of the PEG-copolymer complexes, with the thickness, degree of order, and crystallinity of the PEG microphase determined by the structure of the branched block.

Summary: It is of significant importance to efficiently synthesize pharmacologically active compounds through CO2 conversion. In this study, polyionic liquids (PILs) with adjustable structures and multiple active sites were synthesized. By using epoxy nucleoside as a solid substrate, cycloaddition and carbonate hydrolysis reactions were carried out under the catalysis of polyionic liquid, CO2, and water. The amphiphilicity of P1, the adjustability of alkalinity, and the regulation of the phase state in the presence of water played crucial roles in achieving high selectivity and yield of the reactions. Moreover, the catalyst could be recycled for 6 times while maintaining high catalytic activity and selectivity. This work provides a solvent-free, metal-free, and recyclable green synthetic pathway for chiral drugs, which will further promote the efficient conversion and utilization of CO2.

Summary: In order to improve the therapeutic efficacy of Tirapazamine (TPZ) in cancer treatment, researchers synthesized a novel TPZ derivative and covalently conjugated it to poly (L-glutamic acid) to obtain TPZ nanoparticles (TPZH-NPs). TPZH-NPs showed advantages in prolonged blood circulation, enhanced tumor accumulation, and increased maximum tolerated dose compared to TPZH. Furthermore, TPZH-NPs exhibited significantly enhanced antitumor therapeutic efficiency against 4T1 breast tumors compared to free TPZH.

Summary: A selective activatable prodrug R848-N-3 was developed, which reduced pro-inflammatory cytokines to 1/12 of R848 at the same dose by selectively activating in hypoxic tumors. By using CA4-NPs, the tumor selectivity of R848-N-3 was enhanced, resulting in a 21.45-fold increase in concentration of active R848 in the tumor compared to the heart. Therefore, the azide-masking strategy holds potential for developing tumor-selective prodrugs with reduced toxicity.

Summary: This study finds that the temporal pattern of circulating cell-free DNA (cfDNA) is strongly associated with damage and inflammation parameters in APAP-induced liver injury (AILI). CfDNA is comparable to ALT in predicting mortality and outperforms ALT when combined with ALT in AILI. Depleting cfDNA or neutrophils alleviates liver damage, while adding cfDNA or adoptive transfer of neutrophils exacerbates the damage. The combination of DNase I and N-acetylcysteine significantly attenuates AILI. This study establishes that cfDNA is a mechanistic biomarker to predict mortality in AILI mice. The combination of scavenging cfDNA and reducing oxidative damage provides a promising treatment for AILI.

Bioactive glass (BG), a clinically approved bone graft material, attenuates pro-inflammatory response and reduces inflammatory damage to intestinal organoids in vitro. Zein/sodium alginate-based core-shell microspheres (Zein/SA/BG) are developed for oral delivery of BG to prevent its premature dissolution in the stomach.

Summary: Equipping multiple functionalities on adoptive effector cells is essential for superior antitumor efficacy in solid tumors. However, current cell engineering technologies cannot achieve this in a single step due to differences in the spatial distributions of targets within a cell. In this study, a core-shell anti-phagocytosis-blocking repolarization-resistant membrane-fusogenic liposome (ARMFUL) is proposed to achieve one-step multiplexing cell engineering. This allows for the customization of multimodal cellular functions, enhancing adoptive cell therapy.
