AI Article Synopsis
- - The research focused on creating folate-targeted nanoparticles (FA-ERL-HSA NPs) loaded with Erlotinib and examining their effects on cancer cells in the lab and in rats with glioma.
- - Results showed that FA-ERL-HSA NPs were significantly more effective at killing cancer cells (lower IC values) and inducing apoptosis compared to free Erlotinib in both cell lines tested.
- - In rat models, treatment with FA-ERL-HSA NPs led to a notable reduction in tumor size and an increase in survival rates, with an apoptosis index of 48% compared to just 21% for free Erlotinib.
Article Abstract
The aim of this study was to prepare folate-targeted Erlotinib loaded human serum albumin nanoparticles (FA-ERL-HSA NPs) and investigate in vitro cytotoxic and apoptotic effects using cell lines (U87MG and C6 cells) and an in vivo rat bearing C6 glioma model. The mean size of the FA-ERL-HSA NPs prepared using a desolvation method was 135 nm. In vitro MTT assays demonstrated that FA-ERL-HSA NPs had an IC value of 52.18 μg/mL and 17.53 μg/mL compared to free ERL which had an IC value of 119.8 μg/mL and 103.2 μg/mL for U87MG and C6 cells for 72 h, respectively. Flow cytometry results showed the apoptosis rate with FA-ERL-HSA NPs (100 μg/mL, 72 h) was higher compared to free ERL for both U87MG and C6 cells. Experiments using a rat glioblastoma model via TUNEL assay indicated that the apoptosis index of FA-ERL-HSA NPs was 48 % compared to 21 % for free ERL and the tumor size effectively decreased after a daily injection of 220 μg (2.5 mg/kg) from 87.45 mm (19th day) to 1.28 mm (60th day). The median survival rate of the rats increased after treatment to >100 days which was greater than controls.
