niclosamide

These findings identify Niclosamide as a potent dual STAT1/STAT3 inhibitor capable of reversing IFN-γ- and hypoxia-driven immune evasion. Repurposing Niclosamide may represent a promising strategy to enhance the efficacy of immune checkpoint blockade in solid tumors.

The findings herein demonstrated that mitochondrial uncouplers inhibit MSCP through FTO-dependent m6A demethylation. This work identified mitochondrial uncoupling as a novel and promising therapeutic approach for promoting m6A demethylation and targeting MSCP in metastatic breast cancer.

Canonical NF-κB signaling is mechanistically related to UM cell survival, proliferation, and migration, as shown by pharmacologic inhibition like BAY11-7082, and niclosamide and genetic modulation like microRNA-9. NF-κB signaling, particularly the canonical branch, is required for UM malignancy, while noncanonical signaling is linked with high-risk features. Branch-specific genetic manipulations and clinically relevant models should be employed in future research to maximize therapeutic strategies.

Concurrently, VEGF downregulation and p53 upregulation reflected additional anti-angiogenic and pro-apoptotic effects. Collectively, the lactoferrin-functionalized Nic-NLC produced the most robust antitumor response, with superior ferroptosis induction, redox modulation, and anti-angiogenic activity.

Notably, the predicted metformin plasma Cmax remained within a safe therapeutic window at the 100 mg/kg combination dose but exceeded a safety threshold at 200 mg/kg. By integrating in vivo efficacy testing with quantitative modeling, our study identified the 100 mg/kg combination of niclosamide and metformin as the optimal dose for chemoprevention in a murine FAP model, providing a strong rationale for future clinical translation in FAP management.

Our research revealed comprehensive metabolic alterations in gastric cancer, including upregulated lactate metabolism that promotes tumorigenesis via the lactate shuttle. Niclosamide targets the m6A methylation regulatory protein YTHDF2, which influences genes related to metabolism, indicating its potential as a prospective treatment for GC.

Tyrosine kinase inhibitors (TKIs), such as sunitinib and sorafenib, are standard treatments for renal cell carcinoma (RCC). RNA sequencing (RNA-seq) and bioinformatic analyses showed that niclosamide modulated critical pathways, including BRIP1- and FANCA-mediated DNA repair and E2F2-regulated cell cycle progression. These findings provide proof-of-concept that niclosamide enhances TKI efficacy through modulation of DNA repair and cell cycle pathways, supporting the rationale for DNA damage response (DDR)-targeted combination strategies in RCC.

Given the reduced ATP-generating capacity of SDHB -KO cells, we hypothesized they would be uniquely sensitive to futile cycle induction with mitochondrial ionophores (2,4-Dinitrophenol (2-DNP), BAM15, Niclosamide, Nitazoxanide). Thus, the accumulation of succinate in SDH-deficient tumors inhibits KDM4 activity, impairs DNA repair and yields enhanced susceptibility to Ym155-induced reactive oxygen species (ROS) generation. The identified intrinsic susceptibilities of SDHB -deficient cancers has the potential to be therapeutically leveraged.

PBK is a key regulator of pancreatic cancer and interacts with NCAPG2 to promote tumor progression, suggesting its value as a potential biomarker and therapeutic target for pancreatic cancer.

Herein, we developed a mito-specific "Trojan Horse" nanoplatform (2-pN@LNPs) coloaded with Niclosamide (Nic) and 2-deoxy-d-glucose (2-DG) to attack key metabolism pathways and synergistically ignite pyroptosis for restoring antitumor immunity. Moreover, the synergistic treatment regimen can promote cytotoxic and helper T cells (CD8+/CD4+ T cells) recruitment and M1-type macrophage polarization, facilitating the establishment of a boost in immunological memory to prevent recurrence and metastasis. Overall, this work provides a robust strategy targeting metabolism through mitochondrial uncoupling and glycolysis inhibition, which can effectively improve the antitumor effect, inhibit lung metastasis, and help modulate antitumor immunity.

Therapeutic options are minimal, with nitazoxanide (NTZ) being the only drug available, despite its constrained effectiveness...Mice were immunosuppressed using dexamethasone, infected with C. parvum oocysts, and administered NTZ or NICLO...These findings highlight NICLO's dual therapeutic potential, which effectively targets C. parvum infection and mitigates its tumorigenic effects by disrupting key signaling pathways involved in ileocecal cancer progression. This study provides novel insights into NICLO's chemotherapeutic efficacy in managing cryptosporidiosis and its associated oncogenic potential.

In addition, the LEF1 inhibitor niclosamide increased ovarian cancer sensitivity to Cisplatin and PARPi in patient-derived organoids and Niraparib-resistant cell lines. These findings indicate that LEF1 is a potential therapeutic target for overcoming resistance to chemotherapy based on platinum and PARPi in EOC.
