Construction of Hollow Mesoporous Selenium Loaded With Carboplatin and Clacked With Bevacizumab-Functionalized Albumin Nanoparticles for HER2+ Lung Cancer.

Lung carcinoma is one of the most severe types of cancer, characterized by a dismal prognosis and low overall survival rate, primarily due to late diagnosis and the ineffectiveness of standard treatments. Hence, this study aimed to develop bevacizumab (BZ)-functionalized albumin (BS)-clad, carboplatin (CP)-loaded hollow mesoporous selenium (HMS) nanoparticles (BBHMSC) for the targeted administration of HER2+ Calu-3 lung cancer. The structural properties of these nanoparticles were characterized using transmission electron microscopy (TEM). Cell viability was assessed using the 3-[4,5-dimethylthiazol-2-yl]- 2,5-diphenyltetrazolium bromide (MTT) assay. The images were obtained from fluorescence microscopy. The in vitro characterization of the pharmacological characteristics indicated that BBHMSC was uniformly disseminated, with a particle size of 171.52 ± 4.3 nm. In vitro release tests demonstrated that BBHMSC proficiently regulated the release of CP in the tumor microenvironment (elevated glutathione concentration), achieving a cumulative release rate of 87.1 ± 3.9% over 48 h. A cellular uptake assay validated that BBHMSC has an effective tumor-targeting capability. In vitro cell investigations, MTT studies, have shown that BBHMSC dramatically suppresses proliferation and growth. Further, BBHMSC enhances the apoptosis of HER2+ Calu-3 cells by fluorescence and flow cytometry methods. The data indicate that BBHMSC may be an effective targeted therapy for HER2+ti lung cancer.
