Cellular interactions are more complex at the GC stage than in the premalignant lesions. Collectively, our study offers a comprehensive insight into the evolving gastric mucosal microenvironment and validates the pro-tumor role of activated mast cells under H. pylori infection.

This study highlights CUR's potential in treating EC, particularly in CD47 overexpression cases. These results clarify the molecular interactions and provide a basis for future research on CUR-based therapies targeting EC progression pathways.

Limiting PA intake or targeting the ACSL5/COX2/EP4 axis enhanced paclitaxel efficacy in a breast cancer mouse model. Collectively, these findings highlight the critical role of PA and ACSL5/COX2/EP4 signaling in lung metastasis, which can act as promising targets for enhancing the efficacy of chemotherapy in BC patients with lung metastasis.

The increased abundance of L. reuteri and L. murinus was associated with regulated cellular proliferation, reduced TNF-α production, and decreased expression of COX-2, cyclin D1, and Bcl-2. In conclusion, the results obtained signify the nutraceutical potential of phloretin in restoring the intestinal barrier, maintaining the beneficial gut microbial population, and amelioration of CAC in mice.

Tumor-intrinsic activation of the NRF2-COX2-PGE₂ axis drives immune cold TMEs and mediates Atez/Bev resistance in HCC. Targeting this pathway may enhance efficacy, and plasma PGE₂ represents a non-invasive biomarker for stratification.

These results provide insight into the ability to use COX2 as a biomarker for suspected breast cancer patients in Iraq.

Two oligopeptides (5 mM) induced sustained Ca2+ responses (> 5 min), and all four reduced ROS (p < 0.0001); SKEGGKVT (50 μM) also significantly inhibited COX2 expression (p = 0.018). These findings highlight spent hens as a good source of multifunctional umami peptides.

Comparative analyses indicated that TRin7 exhibited slightly greater potency, consistent with its lower binding free-energy profile in MM/PBSA calculations. Collectively, these findings establish TRin7 and TRin8 as promising small-molecule antagonists of TLR9 and highlight the utility of integrating machine learning with structural modeling and cellular validation in rational drug discovery.

In conclusion, these findings demonstrate that AGEs increase PGE2 production in Ca9-22 cells primarily through a signaling cascade involving RAGE and the TLR4-PKC-NF-κB pathway. Our results suggest TLR4 as a critical mediator that contributes to AGEs-induced inflammation.

Ferroptosis was induced in B-ALL cells using erastin...PRDX1 knockdown further reduced the viability of B-ALL cells treated with the ferroptosis activator ML210, and treatment with the ferroptosis inhibitor liproxstatin-1 significantly reversed the suppressive effect of PRDX1 knockdown on xenograft tumor growth. Mechanically, PRDX1 deletion triggered ferroptosis in B-ALL cells by inhibiting the cAMP pathway. PRDX1 deficiency modulates ferroptosis in B-ALL cells by blocking the cAMP pathway, which offer a novel perspective on the pathogenesis of B-ALL.

Exosomes derived from these microbiota enhance neuronal uptake and trigger markers of ferroptosis, as evidenced by increased expressions of ATG5 and COX2, along with decreased levels of GPX4 and FTH1. These findings establish a mechanistic link between microbial dysbiosis, ferroptosis, and cognitive decline in POCD, providing new insights into potential therapeutic targets for CRC-associated POCD.

Our findings uncover a new function of cytoplasmic p21 in regulating CSC properties through NFκB modulation. Screening p21 subcellular localization may stratify CRC patients with high metastatic risk providing a basis for CSC-targeted therapeutic strategies.
