Pharmacologic targeting of NDUFS4 using the niclosamide analog ARVib-7 phenocopied genetic depletion, suppressing mitochondrial respiration and enhancing olaparib efficacy to inhibit the growth of resistant spheroids. These findings identify NDUFS4 as a key mediator of PARPi resistance and a therapeutic vulnerability in advanced prostate cancer. Targeting NDUFS4 disrupts OxPhos and induces ferroptosis, providing a strong rationale for combination strategies with PARPis to overcome drug resistance.
S1P/STAT3/Shh/Gli1/FoxM1 pathway plays an important role in PASMCs proliferation and pulmonary arterial remodeling. Targeting this cascade may have potential value for the management of PAH.
These findings indicate that combined curcumin and doxorubicin induce apoptosis primarily through JNK-dependent MAPK signaling, accompanied by stress-associated cellular responses.

Consistently, pharmacological inhibition of STAT3 by S3I-201 abolishes HDGF-induced lipogenic gene expression and hepatic steatosis in mouse models...Together, these findings uncover a mechanism that couples hepatic lipogenesis to intrahepatic macrophage activation, driving both steatosis and inflammation in MASLD. Targeting the HDGF-STAT3 pathway and exosomal HDGF secretion may represent a potential therapeutic strategy for ameliorating metabolic dysfunction and hepatic inflammation in MASLD and related disorders.
Moreover, they effectively promote CRT exposure, HMGB1 release, and ATP secretion in 4T1 cells. Furthermore, in a murine breast cancer model, CMCS-D + C/NPs significantly upregulate the expression of proteins such as CD8 and Caspase-3, cytokines (IFN-γ and IL-6), and Granzyme B, demonstrating favorable antitumor efficacy.

It also induced significantly greater cytotoxicity than sorafenib ( p<0.05 ) in the PDO. Mechanistically, SSL-0024 suppressed major oncogenic pathways including AKT-mTOR-STAT3, RAF, and Wnt/β-catenin. SSL-0024 overcomes key pharmacokinetic limitations of niclosamide while maintaining potent anti-tumor activity, supporting its further development as an orally bioavailable therapeutic candidate for HCC.
We summarize the clinical translation progress of ACT001, including its safety and pharmacokinetic profiles, discuss emerging delivery systems such as micelles, and review the patent landscape of PTN derivatives. By integrating mechanistic insights with progress in clinical applications and drug delivery, this review provides a foundation for further mechanistic studies and supports the translational development of PTN-based therapies for respiratory disorders.
