Summary: dcECM hydrogels derived from porcine ears through enzymatic digestion show good biocompatibility for delivering chondrocytes and forming subcutaneous cartilage in vivo. The structural and gelation kinetics of the hydrogels vary with ECM concentrations, with 10 mg/ml hydrogels supporting adhesion and proliferation of chondrocytes in vitro. In vivo, 10 mg/ml dcECM hydrogel grafts exhibit similar qualities to native cartilage, indicating their potential for tissue engineering applications in ear cartilage regeneration.

Summary: Deferoxamine (DFO) is an FDA-approved iron-chelating agent with good therapeutic efficacy, but its short blood half-life poses challenges for patients who require frequent administrations. By integrating crosslinked hyaluronic acid and Pluronic F127 into an injectable hydrogel formulation, a prolonged release of DFO nanochelators is achieved, significantly extending the half-life and demonstrating potential for the treatment of iron overload disorders.

Summary: By oxidative oligomerization of catecholic compounds, gelatin can be functionalized with caffeic acid (CA) oligomers to enhance its bioadhesive properties. Ex vivo adhesion tests on pig lungs showed a 33-fold improvement in adhesion strength compared to gelatin methacryloyl controls, with increased toughness and stretchability. Functionalization with CA oligomers also allows for rapid gel formation at room temperature, adjustable viscosity for injectability, and enhanced antioxidant effects.

Summary: In this study, a thermosensitive hyaluronic acid-g-poly(N-isopropylacrylamide) copolymer was synthesized and found to have sol-to-gel phase transition temperatures suitable for use as a scaffold for chondrocyte delivery. In vitro cell culture experiments showed that cells could proliferate in the polymer scaffold with full retention of cell viability and exhibit the phenotypic morphology of chondrocytes. In vivo studies confirmed the formation of ectopic cartilage when the polymer was used as a cell delivery vehicle. These findings suggest the promising potential of the thermosensitive hydrogel in cartilage tissue engineering applications.

Summary: This study aims to develop an injectable hydrogel scaffold using a porcine cartilage-derived acellular matrix (CAM). The CAM is cross-linked with a biocompatible polyethylene glycol (PEG) cross-linker to replace glutaraldehyde (GA) cross-linker. The injectable Cx-CAM-PEG suspension shows controllable rheological properties and injectability. The in vivo formed Cx-CAM-PEG hydrogel scaffold exhibits host-cell infiltration and minimal inflammation, making it a potential candidate for (pre-)clinical scaffolds.

Summary: CLIP4 is downregulated in breast cancer and correlated with hormone receptor status and breast cancer grading. Its expression is positively associated with basal-like and triple negative breast cancer status, and ectopic expression is linked to poor prognosis. Analysis of genes co-expressed with CLIP4 revealed enrichment of multiple signaling pathways in the high expression phenotype.

Summary: Recent studies have shown that tumor microenvironment (TME) immune cells play a significant role in affecting the development and progression of breast cancer, but lack of sufficient evidence limits the clinical application of immunotherapy for advanced and metastatic breast cancers. Targeting STAT3 and/or combining it with radiotherapy may enhance anti-cancer immune responses and rescue the systemic immunologic microenvironment in breast cancer.STAT3 function in TME of breast cancer involves multiple types of immunosuppression and is associated with tumor cell metastasis, in addition to its oncogenic role in tumor cells.

Summary: This study demonstrates promising clinical application of radiotherapy in combination with EGF@DOX-NPs for lung cancer treatment. The targeted nanoparticles selectively accumulate at the tumor site due to radiation-induced outburst of local intra-tumoral blood vessels. Compared with DOX alone, EGF@DOX-NPs significantly decrease tumor cell viability and migration, and increase apoptosis rates. Moreover, EGF@DOX-NPs increase survival of tumor-bearing mice through radiation-induced aggregation without apparent systemic toxic effects. Therefore, the combination of radiotherapy and EGF@DOX-NPs shows potential for improving clinical outcomes in lung cancer treatment.

Summary: Tumor hypoxia negatively affects the clinical treatment of lung cancer. This study proposes a novel drug delivery strategy by implanting anaerobic Bifidobacterium infantis as a preimplanted target and using bacterial antibody decorated nano-drug missiles to enrich therapeutic drugs in the tumor hypoxic area. The study confirms the excellent anti-tumor effect of this strategy, with reduced systemic side effects. This work provides an elegant platform for in vivo delivery of chemotherapeutic drugs to the hypoxic area of solid tumors.

Summary: In this study, albumin-modified gold nanoparticles (Alb-GNPs) were prepared and their radiosensitizing effects and biotoxicity in human non-small-cell lung carcinoma tumor-bearing mice models were observed. The prepared nanoparticles (Alb-GNPs) showed excellent colloidal stability and biocompatibility with a mean size of 205.06 +/- 1.03 nm. Clone formation experiments demonstrated that Alb-GNPs exerted excellent radiosensitization with a higher sensitization enhancement ratio (SER) of 1.432 compared to X-ray alone. Alb-GNPs could accumulate favorably in tumors and their combination with radiotherapy exhibited a greater radiosensitizing effect and anti-tumor activity. Additionally, no toxicity or abnormal irritating response was observed with the application of Alb-GNPs.
