RHOJ controls EMT-associated resistance to chemotherapy

Maud Debaugnies et al.

Summary: This study reveals that cancer cells undergoing EMT are highly resistant to various anti-cancer therapies. RHOJ, a small GTPase preferentially expressed in EMT cancer cells, controls resistance to therapy by enhancing the response to replicative stress and activating the DNA-damage response. RHOJ interacts with proteins that regulate nuclear actin, and inhibition of actin polymerization sensitizes EMT tumor cells to chemotherapy-induced cell death in a RHOJ-dependent manner.

Cation-π Interaction Trigger Supramolecular Hydrogelation of Peptide Amphiphiles

Shuang Chen et al.

Summary: As an important noncovalent interaction, cation-p interaction plays a crucial role in various biological and chemical applications. In this study, peptide amphiphiles were designed with cation-p interaction pairs, which could self-assemble into supramolecular hydrogels under physiological conditions. The influence of cation-p interaction on peptide folding propensity, morphology, and rigidity of the hydrogel was thoroughly investigated. The results showed that cation-p interaction can serve as a major driving force for peptide folding, resulting in the formation of fibril-rich hydrogels. Additionally, the designed peptides showed high efficacy in cytosolic protein delivery. This work provides a novel strategy to generate supramolecular biomaterials using cation-p interactions for the first time.

Fibroblast Activation Protein-α Responsive Peptide Assembling Prodrug Nanoparticles for Remodeling the Immunosuppressive Microenvironment and Boosting Cancer Immunotherapy

Mengqi Sun et al.

Summary: The study introduces a novel amphiphilic bifunctional PD-1/PD-L1 peptide antagonist PCP, co-delivering doxorubicin (DOX) and R848 through co-assembly of a multi-agent prodrug (PCP@R848/DOX) specifically cleaved by fibroblast activation protein-alpha (FAP-alpha) in the tumor stroma. This activation leads to the localized release of DOX and R848, triggering immunogenic cell death (ICD) and reprogramming tumor-associated macrophages (TAMs) to elicit antitumor immunity, while sustained release of PD-1/PD-L1 antagonists further blocks the PD-L1 pathway for cytotoxic T lymphocyte activation, presenting a new paradigm in combination immunotherapy for cancer treatment.

Summary: Immunotherapy offers a promising approach for cancer treatment by re-activating the immune system. However, the response rate of current strategies is still low. In this study, a cascade amplification nanocomposite was designed to enhance the response rate. The nanocomposite consists of an immune adjuvant, a matrix metalloproteinase 2 responsive sequence, a photosensitizer, and an immune checkpoint inhibitor. In vivo experiments demonstrated that this nanocomposite achieved almost 100% objective response rate by promoting T lymphocyte activation and immune cell infiltration in tumors.
