Dual targeting and bioresponsive nano-PROTAC induced precise and effective lung cancer therapy.

Epigenetic regulation has emerged as a promising therapeutic strategy for lung cancer treatment, which can facilitate the antitumor responses by modulating epigenetic dysregulation of target proteins in lung cancer. The proteolysis-targeting chimera (PROTAC) reagent, dBET6 shows effective inhibition of bromodomain-containing protein 4 (BRD4) that exerts antitumor efficacy by degrading BRD4 via the ubiquitin-proteasome system. Nevertheless, the low tissue specificity and bioavailability impede its therapeutic effects and clinical translation on lung cancer treatment.

The use of amphiphilic copolymer in the solid dispersion formulation of nimodipine to inhibit drug crystallization in the release media: Combining nano-drug delivery system with solid preparations.

Solid dispersion is a widely used method to improve the dissolution and oral bioavailability of water-insoluble drugs. However, due to the strong hydrophobicity, the drug crystallization in the release media after drug dissolution and the resulted decreased drug absorption retards the use of solid dispersions. It is widely known that the amphiphilic copolymer can encapsulate the hydrophobic compounds and help form stable nano-dispersions in water.

A fluorinated low-molecular-weight PEI/HIF-1α shRNA polyplex system for hemangioma therapy.

Hemangioma, one of the most common angiogenic diseases in infants and children, is characterized by the abnormal and aggressive proliferation of vascular endothelial cells. Advanced therapeutic strategies like RNA interference can inhibit the expression of target proteins at the translational level, but they are rarely used in hemangioma treatment owing to the lack of safe carriers. In this study, we showed for the first time that RNAi technology targeting HIF-1α (hypoxia-inducible factor-1 alpha) could benefit hemangioma therapy effectively.
