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.

While photoactivation of verteporfin (VP), a photosensitizer, has demonstrated success for overcoming MDR through direct protein aggregation upon photoactivation and through adenosine triphosphate (ATP) depletion, the impact of VP's formulation on P-gp function and cellular energetics has not been fully characterized in this context...Photodynamic priming with NanoVP at sub-cytotoxic light doses enhanced P-gp substrate retention within the cells without damaging P-gp protein, indicating ATP depletion as the primary mode of functional inhibition. These findings highlighted NanoVP's clinical potential to enhance chemotherapeutic efficacy via photoactivation-based modulation of P-gp's function in multidrug-resistant cancers.

The 15q15 deletion promotes BM development through aberrant MYC signaling and the subsequent reprogramming of carbohydrate metabolism.

Furthermore, our results demonstrated that the combination of Elesclomol with HSP90 inhibitor Ganetespib exhibited synergistic anti-tumor effects. In conclusion, our findings that mitochondria-translocated ALDH1L1 functions as a feedback regulator of redox homeostasis in cancer cells to enhance the resistance to pro-oxidative therapy can provide critical insights into developing effective pro-oxidative therapies against tumors.

In vivo experiments also demonstrated that verteporfin inhibited the in-situ tumor progression and ivonescimab enhanced the efficacy of immunotherapy in MS4A1 low tumor-bearing mouse. The MS4A1/M1 macrophage axis was identified as a crucial regulator of malignancy in LUAD, indicating MS4A1 as a promising novel therapeutic target for advanced LUAD treatment.
