  • Storming glioblastoma’s fortress: kaempferol-powered spatiotemporal nanotherapy hierarchically breaking-capturing-disarming tumor defenses via programmable metabolic phototherapy amplification (2026) · Advanced Composites and Hybrid Materials · doi

    Abstract The efficacy of conventional therapies against glioblastoma (GBM) is limited by a hierarchical defense system comprising the blood-brain barrier (BBB) that restricts the entry of most therapeutic drugs, physical-chemical barriers of tumor that hinder drug penetration and retention, and intrinsic or adaptive metabolic reprogramming that empowers treatment resistance, collectively rendering over 98% of therapeutic agents ineffective.

  • Research progress of small molecule targeted drugs for non-small cell lung cancer (2026) · Frontiers in Oncology · doi

    Future research should prioritize accelerating the clinical translation of investigational drugs, exploring combination treatment regimens, identifying novel molecular targets, and optimizing the overall system of molecular targeted therapy. - Research should focus on developing novel therapies that can overcome acquired drug resistance and penetrate the blood-brain barrier.

    The blood-brain barrier restricts the delivery of several drugs, rendering them ineffective against the growth of tumors. - The lack of comparison groups and the insufficient number of participants in some trials limit the conclusions that can be drawn. - The natural characteristic of the central nervous system known as 'immune isolation' creates an impediment to treatment.
