Our findings support the pathogenic role of the CHYMASE mutation in nsHGF, establish chymase deficiency and consequent YAP/TAZ activation as the underlying mechanism and propose verteporfin-loaded exosomes as a promising therapeutic strategy for nsHGF-associated gingival overgrowth.

This approach, using hyaluronic acid nanoparticle (HANP)-formulated verteporfin (HANP/VP), concurrently induced nuclear- and mitochondrial-DNA damage, promoted immunogenic cell death (ICD), and drove T-lymphocyte infiltration into the tumor microenvironment (TME)...Overall, our findings established HANP/VP as a multifunctional nanomedicine that reprogrammed the TME and elicited potent antitumor immunity through dual DNA damage and STING activation. The study highlights a promising translational strategy for overcoming immunotherapeutic resistance in UM and converting immunologically "cold" tumors into "hot" ones, thereby improving responses to immune checkpoint blockade (ICB).

FAM189A2 can be considered as a potential diagnostic and prognostic marker associated with LUAD, and suppresses the proliferation and glycolytic metabolism of LUAD cells via WWP2-LATS1-YAP signaling, which will provide a corresponding theoretical foundation for the development of small molecule inhibitors.

Our results reveal the F-actin assembly is inhibited by silibinin, and this results in G2/M cell cycle arrest in human breast cancer cells, providing new ideas for anti-cancer therapies including TNBCs.

The effects of the SNHG26-CDKN2A axis on Cu + ELES(copper plus elesclomol)-induced cuproptosis and CD8+ T cell-mediated anti-tumour immunity were evaluated through cell viability, apoptosis, co-culture cytotoxicity and migration assays...Our findings reveal a novel regulatory axis whereby SNHG26 promotes CRC progression by destabilising CDKN2A mRNA, resulting in enhanced cell proliferation, cuproptosis and immune evasion. This study provides new insights into the molecular mechanisms underlying CRC development.

The YAP inhibitor Verteporfin blunted MELK-driven PASMC proliferation and migration, underscoring the central role of YAP/TAZ signaling. Finally, in vivo pharmacological inhibition of MELK by OTS167 markedly reduced right ventricular systolic pressure, hypertrophy, and pulmonary vascular remodeling in Su/H mice, confirming the therapeutic relevance of MELK targeting in PAH. Collectively, these findings identify MELK as a novel regulator of PASMC pathobiology in PAH and suggest that it may represent a potential therapeutic target.

cDVPMA was constructed by encapsulating the stimulator of interferon genes (STING) agonist 2'3'-cGAMP in the aqueous core of a tertiary ammonium group-containing polymersome, while embedding both the photosensitizer verteporfin-phospholipid (VL) and thrombin inhibitor dabigatran etexilate within the hydrophobic layer. In a 4T1 mouse breast cancer model, cDVPMA combined with near-infrared (NIR) laser irradiation elicited robust antitumor immunity, significantly suppressing primary tumor growth and metastasis, while establishing durable immune memory that prevented tumor recurrence. This study provides valuable insights into the development of nanomedicines for immunotherapy targeting tumors in a hypercoagulable state.

In vivo experiments revealed that ES inhibited tumor growth and upregulated PCK2. Taking together, our findings reveal that the ES-ER stress-PCK2 axis is a critical mediator of copper-induced metabolic disruption, providing a rationale for targeting cuproptosis pathways in LUAD therapy.

In vitro experiments, the combination of elesclomol (a copper ion carrier) and bortezomib (Bortezomib) demonstrated a synergistic anti-myeloma effect through excessive intracellular reactive oxygen species generation. This study provides valuable insights into the role of CRGs in MM, potentially aiding in prognosis prediction and the development of effective, personalized therapeutic strategies.
