SIRT3 promotes GC progression and chemoresistance by deacetylating and stabilizing the mitochondrial ADP/ATP translocator SLC25A6 (ANT3), thereby enhancing mitochondrial metabolic activity. The SIRT3-ANT3 axis represents a novel molecular mechanism driving GC malignancy and chemoresistance and may serve as a promising therapeutic target for improving treatment efficacy in GC.

Six prognostic genes, particularly RAB25 and PLAU, influence ESCC progression and immune microenvironment remodeling.

Our findings reveal an intrinsic SLFN11-dependent vulnerability in ccRCC that synergizes with alkylating agents to induce an acquired PARP-1 dependency, thereby sensitizing BRCA1/2-WT tumors to PARP inhibition. Therefore, this work uncovers a potential therapeutic strategy for targeting SLFN11-high kidney cancers.

These findings suggest that rapamycin enhances the mechanistic efficacy of cisplatin by specifically targeting and reducing cisplatin-induced stemness (CD133+ CSC population). This study proposes a viable combination therapy for HNSCC involving an mTOR inhibitor and a platinum-based drug to overcome CSC-mediated resistance.

In addition, EV-enriched non-coding RNAs, such as miR-25-3p, miR-3591-3p, and lncRNA H19, regulate PI3K-AKT-mTOR, JAK2/STAT3, and related pathways to promote myeloid reprogramming, immune escape, and temozolomide resistance...Targeting EV biogenesis, release, uptake, or specific immunosuppressive cargoes may provide promising opportunities to overcome resistance and improve immunotherapy for glioma. Future studies should focus on deciphering EV-mediated immune regulatory networks, identifying robust glioma-specific EV biomarkers, standardizing EV detection platforms, and developing precision EV-based therapeutic strategies.

In addition, mTOR pathway activity and responsiveness to mTOR inhibitors (rapamycin and ipatasertib) and chemotherapeutic agents (cisplatin) were assessed. Compared with 2D monolayer cultures, 3D TMSs exhibited reduced mTOR signaling activity, which led to significantly decreased sensitivity to mTOR inhibition. These findings indicate that 3D bioprinted breast cancer models recapitulate key structural and signaling features of in situ tumors more accurately than 2D systems, highlighting their potential value for preclinical drug testing and mechanistic studies.

LP treatment ameliorated these pathological alterations by restoring antioxidant enzyme activities, downregulating proinflammatory and proapoptotic signals, mitigating ER stress and autophagy activation, and reducing PI3K/AKT/mTOR protein expression. These findings demonstrate that LP exerts a renoprotective effect against OXI-induced kidney injury through multi-targeted molecular mechanisms, including modulation of inflammation, oxidative stress, autophagy, apoptosis, and survival signaling pathways.

This study comprehensively identifies the vessel-threatening effects of cisplatin (CDDP), carboplatin (CBP), and oxaliplatin (OXA) and aims to compile an analytical model. The results suggest activation of the oxidative stress pathway through Nrf2 inhibition and increased ICAM1 levels, alongside pathway‑specific alterations such as reduced HIF1A and NOS3 expression and decreased VCAM1 levels. Early cardiovascular monitoring and Nrf2‑targeted therapy warrant further investigation.

The most potent derivative identified was 2-(3-(benzo[d]thiazol-2-yl)-1H-indol-1-yl)-N-(2,4-dimethoxyphenyl)acetamide (9d) which demonstrated IC50 values of 7.9 ± 1.6, 16.1 ± 0.5, and 9.3 ± 2.2 µM against A549, SW480, and HepG2 cells, respectively, comparable or even superior to those of cisplatin (IC50s were 5.7 ± 1.6, 15.2 ± 0.3, and 14.3 ± 1.9 µM for A549, SW480, and HepG2 cells, respectively)...In silico predictions regarding drug-likeness, pharmacokinetics, and toxicological characteristics suggest that the promising derivative 9d could be proposed as a potential anticancer drug for further preclinical studies. Molecular docking studies revealed that 9d was well accommodated within the endothelial growth factor receptor (EGFR) active site.

Using mitomycin C (MMC) as a model drug, we show that MAC enables precise hypoxia-triggered intracellular drug release, efficient lysosomal escape, and enhanced mitochondrial dysfunction...In vivo studies further demonstrate that MMC-MAC achieves rapid and sustained tumor accumulation, significantly suppresses tumor growth, induces robust apoptosis, alleviates tumor hypoxia, and exhibits improved systemic biosafety compared with free MMC. This work establishes a supramolecular-biological hybrid strategy that integrates host-guest chemistry, albumin-based delivery, and hypoxia-responsive activation into a single platform, providing a modular and generalizable paradigm for constructing tumor microenvironment-selective nanomedicines with enhanced therapeutic index.
