To overcome these limitations, we engineered β-selenoester-crosslinked nanocapsules delivering Gefitinib, designed to induce opposite cell fates in cancer cells and macrophages...This selective cell fate programming yielded no macrophage toxicity at cancer-cell IC50 levels and a 91.1 % tumor suppression in vivo. Collectively, this work demonstrates a divergent cell fate induction strategy based on β-selenoester-crosslinking for integrated TAM-mediated immunotherapy.

A novel prediction model was constructed based on seven RB-related signature genes for prognostic prediction in HCC patients. Targeted inhibition of CGREF1 may represent a potential strategy to improve therapeutic outcomes in HCC.

Concurrent PEM with EGFR-TKI treatment slowed TMB accumulation rate and resistance acquisition in EGFR-mutated NSCLC compared to single EGFR-TKIs in vitro.

RHBDD1 facilitates CC progression by promoting proliferation, EMT, migration, invasion, and tumorigenesis through activation of the EGFR/PI3K/AKT pathway, likely via direct receptor-level interaction. Targeting this regulatory node may offer a promising therapeutic approach for CC.

Co-administration experiments were also performed using Gefitinib, a drug commonly used in NSCLC therapy...Importantly, at active concentrations (150-250 µg/mL) SPPs were not found to produce cytotoxicity or apoptosis in 16HBE cells. Overall, these findings suggest that SPPs may selectively target NSCLC cells by promoting redox imbalance, apoptosis, and immune response, without affecting healthy cells, supporting their potential as natural adjuvants in lung cancer treatment.

Despite the development of first-generation reversible inhibitors like Gefitinib and Erlotinib, acquired resistance necessitated the discovery of highly potent irreversible inhibitors effective against drug-resistant mutants. Herein, we report the design, synthesis and biological evaluation of novel 4-anilino quinazoline derivatives, bearing various alkynyl substituents at position 6, expected to bind to the hinge Met793 residue of EGFR. The effects of the derivatives on various cancer cell lines in terms of cytotoxic/cytostatic activity, interference with cell cycle phase distribution, and suppression of EGFR phosphorylation set the basis for the design of more potent derivatives.

Since 1997, EGFR tyrosine kinase inhibitors (EGFR-TKIs) have evolved from first-generation agents, such as gefitinib, erlotinib, and icotinib, to second-generation agents like afatinib and dacomitinib, now to third-generation agents, including osimertinib, aumolertinib, furmonertinib, befotertinib, rezivertinib, rilertinib, limertinib, lazertinib, mifanertinib for EGFR L858R, sunvozertinib for EGFR exon 20 insertion (20ins), and zorifertinib for EGFR-sensitive mutation with brain metastases. Over the past 30 years, substantial advancements have been made in the comprehensive management of EGFR-mutant NSCLC. This systemic review provides the history of the development of EGFR-TKI therapy for NSCLC from 1997 to 2026, highlighting clinical milestones, emerging therapies, and future directions in this rapidly evolving field.

Cell counting kit-8 (CCK-8) assay, 5-Ethynyl-2'-deoxyuridine (EdU) assay, colony formation assay and Annexin V-FITC/PI assay were performed to detect the anti-cancer effects of HQD and EGFR-TKIs (1st generation EGFR-TKI gefitinib or 3rd generation EGFR-TKI Osimertinib) in different NSCLC cell lines. Moreover, the drug safety, anti-cancer effect and potential mechanism of the therapy of HQD and EGFR-TKIs were confirmed in vivo. HQD enhances the anti-cancer effect of EGFR-TKIs in NSCLC through ROS-mediated CSC makers inhibition by suppressing stat3/GPX4 axis to induce redox ratio, providing a novel strategy for the treatment of NSCLC patients.

EGFR-TKI-resistant cell lines were established by long-term exposure to gefitinib, afatinib, and osimertinib via the PC9 model. Targeting endoplasmic reticulum (ER) stress pathways alongside immune checkpoint inhibitors may be crucial for overcoming resistance mechanisms identified here. These insights provide a rationale for personalized treatment strategies tailored to the immune-related gene-expression profiles observed in EGFR-TKI-resistant NSCLC models, aiming to enhance therapeutic responses and improve clinical outcomes.

This review provides a comprehensive overview of the evolution of four generations of EGFR tyrosine kinase inhibitors (EGFR-TKIs): first-generation reversible inhibitors such as gefitinib and erlotinib; second- and third-generation irreversible inhibitors, including afatinib, dacomitinib, and osimertinib; and emerging fourth-generation agents, such as amivantamab. Future studies should explore combination therapies, antibody-drug conjugates, and next-generation allosteric inhibitors as promising strategies to overcome resistance. The evolution of EGFR-targeted therapy exemplifies the progress of precision oncology and serves as a basis for designing new paradigms in the management of lung cancer.
