BRD4 Degradation Enhanced Glioma Sensitivity to Temozolomide by Regulating Notch1 via Glu-Modified GSH-Responsive Nanoparticles.

Temozolomide (TMZ) serves as the principal chemotherapeutic agent for glioma; nonetheless, its therapeutic efficacy is compromised by the rapid emergence of drug resistance, the inadequate targeting of glioma cells, and significant systemic toxicity. ARV-825 may play a role in modulating drug resistance by degrading the BRD4 protein, thereby exerting anti-glioma effects. Therefore, to surmount TMZ resistance and achieve efficient and specific drug delivery, a dual-targeted glutathione (GSH)-responsive nanoparticle system (T+A@Glu-NP) is designed and synthesized for the co-delivery of ARV-825 and TMZ.

A Targeted and Responsive Nanoprodrug Delivery System for Synergistic Glioma Chemotherapy.

Doxorubicin (DOX) is widely used as a chemotherapeutic agent for both hematologic and solid tumors and is a reasonable candidate for glioma treatment. However, its effectiveness is hindered by significant toxicity and drug resistance. Moreover, the presence of the blood-brain barrier (BBB) brings a crucial challenge to glioma therapy.

Tumor-Microenvironment-Activatable Nanoparticle Mediating Immunogene Therapy and M2 Macrophage-Targeted Inhibitor for Synergistic Cancer Immunotherapy.

Immunotherapy has achieved prominent clinical efficacy in combating cancer and has recently become a mainstream treatment strategy. However, achieving broad efficacy with a single modality is challenging, and the heterogeneity of the tumor microenvironment (TME) restricts the accuracy and effectiveness of immunotherapy strategies for tumors. Herein, a TME-responsive targeted nanoparticle to enhance antitumor immunity and reverse immune escape by codelivering interleukin-12 (IL-12) expressing gene and colony-stimulating factor-1 receptor (CSF-1R) inhibitor PLX3397 (PLX) is presented.

Outer membrane vesicles produced by coral-associated Vibrio coralliilyticus inhibit bacteriophage infection and its ecological implications.

The potential to produce and release outer membrane vesicles (OMVs) is evolutionarily conserved among bacteria, facilitating interactions between microbes. OMV release and its ecological significance have rarely been reported in coral holobionts. Here, via transmission electron microscopy (TEM), we discovered that the coral-associated strain Vibrio coralliilyticus DSM 19607 produced OMVs in culture.

Effect of chitosan/inorganic nanomaterial scaffolds on bone regeneration and related influencing factors in animal models: A systematic review.

Bone tissue engineering (BTE) provides a promising alternative for transplanting. Due to biocompatibility and biodegradability, chitosan-based scaffolds have been extensively studied. In recent years, many inorganic nanomaterials have been utilized to modify the performance of chitosan-based materials.

Cultured Bacteria Provide Insight into the Functional Potential of the Coral-Associated Microbiome.

Improving the availability of representative isolates from the coral microbiome is essential for investigating symbiotic mechanisms and applying beneficial microorganisms to improve coral health. However, few studies have explored the diversity of bacteria which can be isolated from a single species. Here, we isolated a total of 395 bacterial strains affiliated with 49 families across nine classes from the coral Pocillopora damicornis.

sp. nov., isolated from mucus of a stony coral.

A Gram-stain-positive, aerobic, motile, coccus-shaped bacterium, designated strain SCSIO 13315, was isolated from mucus of the coral sp. collected from Luhuitou fringing reef (Sanya, Hainan, PR China). Analysis of the 16S rRNA gene sequence showed that strain SCSIO 13315 exhibits 95.
