Objectives: Novel D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) modified lipid nanocapsules (LNC) were prepared with the aim of improving the effectiveness of simvastatin (SIM) in hepatocellular carcinoma (HCC). The present study, therefore, sought to investigate the effect of size-optimized SIM-loaded LNC on epithelial-to-mesenchymal transition (EMT) in HCC, providing insights on the implication of phosphatase and tensin homolog (PTEN)/protein kinase B (AKT) axis.
Methods: Two optimized SIM-loaded LNCs with particle sizes 25 nm (SIM-LNC25) and 50 nm (SIM-LNC50) were prepared and biodistribution studies were performed. The anticancer effect of the prepared LNC was evaluated both and . The anti-migratory potential and EMT suppression through PTEN/AKT axis modulation were also explored.
Results: SIM-LNC50 was superior to SIM-LNC25 in both and experiments, as evidenced by cytotoxicity assays, tumor histopathology, and enhanced apoptosis. SIM-LNC50 also alleviated the migratory potential of HCC cells. Moreover, EMT markers implied a transition of tumor cells toward the epithelial rather than the mesenchymal phenotype both and . PTEN/AKT axis modulation was also evident with SIM-LNC50.
Conclusion: The present study, therefore, suggests the efficacy of the 50 nm particles in SIM-loaded LNC in HCC by targeting EMT via modulating the PTEN/AKT signaling axis.

As a potential drug, antisense oligonucleotides (AO) have considerable application prospects in the field of tumor treatment. However, the main problem to be solved is the lack of an efficient and safe carrier that contributes to reaching the target cancer cells and utilizing the antitumor effect of AO. Here, we designed and developed a novel AO delivery system, which was based on a modified polyethylenimine (PEI) named TPGS-SS-PEI by connecting tocopherol polyethylene glycol succinate (TPGS) to PEI through the disulfide bond (SS) and the biomimetic red blood cell membrane vesicles (RVs).

Superparamagnetic iron oxide nanoparticles (SPIONs) have gained significant attention for Magnetic Fluid Hyperthermia (MFH)-based cancer therapy. However, achieving high heating efficiency under a biologically safe Alternating Magnetic Field (AMF) remains a challenge. This study investigates the synthesis and optimization of SPIONs encapsulated in TPGS-stabilized PLGA nanoparticles (TPS-NPs) using a modified single emulsion solvent evaporation (M-SESE) method.

Low water solubility and poor intestinal permeability hinder the oral absorption of curcumin (CUR). To address this, we designed a core-shell structured nanoparticle based on nanodiamonds (NDs) and thiolated chitosan (TCS). First, D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) covalently modified NDs were prepared and loaded with CUR (CUR@NDs-TPGS).

Pancreatic cancer (PC) is currently a leading cause of death worldwide and its incidence is expected to increase in the following years. Chemotherapy with gemcitabine (GEM) is precluded by extensive enzymatic inactivation and clearance, and the nonspecific tissue distribution contributes to unwanted systemic toxicity and tumor resistance. In this work, GEM was encapsulated in d-ɑ-tocopheryl polyethylene glycol succinate (TPGS) micelles by 'stapling' GEM at 4-NH position with vitamin E succinate (VES) through a highly stable amide bond, achieving successful GEM hydrophobization by means of a prodrug system (VES-GEM).

Recent advances in immune checkpoint inhibitors (ICIs), particularly those targeting PD-1/PD-L1, have transformed cancer treatment. However, their efficacy is often hampered by the immunosuppressive tumor microenvironment (TME). Here, we developed a cantharidin-loaded nanomedicine (CA@TPGS-AmP), composed of D-α-tocopheryl polyethylene glycol succinate (TPGS) and naturally derived amphiphilic peptides (AmP), designed to enhance PD-1 blockade via induction of immunogenic cell death (ICD).
