Nanomedicine in cancer therapy

Signal Transduction and Targeted Therapy, Journal Year: 2023, Volume and Issue: 8(1)

Published: Aug. 7, 2023

Cancer remains a highly lethal disease in the world. Currently, either conventional cancer therapies or modern immunotherapies are non-tumor-targeted therapeutic approaches that cannot accurately distinguish malignant cells from healthy ones, giving rise to multiple undesired side effects. Recent advances nanotechnology, accompanied by our growing understanding of biology and nano-bio interactions, have led development series nanocarriers, which aim improve efficacy while reducing off-target toxicity encapsulated anticancer agents through tumor tissue-, cell-, organelle-specific targeting. However, vast majority nanocarriers do not possess hierarchical targeting capability, their indices often compromised poor accumulation, inefficient cellular internalization, inaccurate subcellular localization. This Review outlines current prospective strategies design organelle-targeted nanomedicines, highlights latest progress technologies can dynamically integrate these three different stages static maximize outcomes. Finally, we briefly discuss challenges future opportunities for clinical translation nanomedicines.

Polyphenolic materials are a class of fascinating and versatile bioinspired for biointerfacial engineering. In particular, due to the presence active chemical groups, series unique physicochemical properties become accessible tunable as-prepared polyphenolic platforms, which could delicately regulate cell activities via cell-material contact-dependent interactions. More interestingly, polyphenols also affect behaviors contact-independent manner, arise their intrinsically functional characteristics (e.g., antioxidant photothermal behaviors). As such, comprehensive understanding on relationship between material desired biomedical applications, as well underlying mechanism at cellular molecular level would provide design principles accelerate lab-to-clinic translation platforms. this review, we firstly give brief overview hallmarks governed by surrounding cues, followed introduction engineering strategies. Subsequently, detailed discussion cell-polyphenols interfacial interaction was carefully provided. Lastly, applications were elaborated. We believe that review guidances rational multifunctional extend application window.

Tumor-Generated Reactive Oxygen Species Storm for High-Performance Ferroptosis Therapy

ACS Nano, Journal Year: 2023, Volume and Issue: 17(12), P. 11492 - 11506

Published: June 7, 2023

Ferroptosis therapy (FT) efficacy of tumors suffers from a relatively low concentration Fenton agents, limited hydrogen peroxide (H2O2) content, and insufficient acidity in the tumor environment (TME), which are unfavorable for reactive oxygen species (ROS) generation based on or Fenton-like reactions. The glutathione (GSH) overexpression TME can scavenge ROS abate FT performance. In this study, strategy storm specifically initiated by our developed nanoplatforms (TAF-HMON-CuP@PPDG) is proposed high-performance tumors. GSH initiates HMON degradation, resulting tamoxifen (TAF) copper (CuP) release TAF3-HMON-CuP3@PPDG. released TAF leads to enhanced acidification within cells, reacts with CuP producing Cu2+ H2O2. reaction between H2O2 generates Cu+, that Cu+ Cu2+, forming cyclic catalysis effect. generate GSSG. increased accelerate consumption decreases peroxidase 4 (GPX4) expression. All above reactions cells FT, demonstrated cancer tumor-bearing mice.

The limited drug penetration and robust bacteria-mediated inactivation in pancreatic cancer result the failure of chemotherapy. To fight against these issues, a dual-cascade responsive nanoparticle (sNP@G/IR) that can sequentially trigger deep penetration, killing intratumor bacteria, controlled release chemo-drug, is reported. sNP@G/IR consists hyaluronic acid (HA) shell glutathione (GSH)-responsive polymer-core (NP@G/IR), encapsulates gemcitabine (Gem) photothermal agent (IR1048). polymer core, as an antibiotic alternative, tailored to exert optimal antibacterial activity selectivity. actively homes on tumor due CD44 targeting HA shell, which subsequently degraded by hyaluronidase extracellular matrix. resultant NP@G/IR decreased size reversed charge facilitates penetration. After cellular endocytosis, exposed guanidine kills intracellular bacteria through disrupting cell membranes. Intracellular GSH further triggers cargo. Thus, protected Gem eventually induces apoptosis. Under laser irradiation, hyperthermia IR1048 helps elimination tumors bacteria. Moreover, activates immune response, thereby reinforcing anticancer capacity. Therefore, this eliminates tumor-resident augments delivery efficacy, providing new avenue for improving therapy.
