Enhancement of the anticancer potential and biosafety of BSA-modified, bacterial membrane-coated curcumin nanoparticles
Colloids Surf B Biointerfaces. 2024 Nov;243:114156. doi: 10.1016/j.colsurfb.2024.114156. Epub 2024 Aug 10.
ABSTRACT
Bacteria and bacterial components have been widely used as bionanocarriers to deliver drugs to treat tumors. In this study, we isolated bacterial outer membrane vesicles (OMVs) with good stability and high yield for macrophage polarization and cell recruitment. Using ultrasound baths, these bacterial OMVs were combined with curcumin nanoparticles (OMV CUR NPs), following which these nanoparticles were modified with bovine serum albumin (BSA) to achieve high biosafety and tumor-targeting effects. The particle size, PDI, and zeta potential of the BSA-OMV CUR NPs were 157.9 nm, 0.233, and -15.1 mV, respectively. The BSA-OMV CUR NPs exhibited high storage stability, low cytotoxicity, sustained release, enhanced cellular uptake of CUR, induction of tumor cell apoptosis, and inhibition of tumor cell proliferation and migration. By determining the survival rate, body length, heart rate, head size, eye size, and pericardium size of the zebrafish, we found that the BSA-OMV CUR NPs were safe for application in vivo. Moreover, an increase in antiproliferation, antiangiogenic and antimetastatic effects of BSA-OMV CUR NPs was demonstrated in wild-type and transgenic tumor-transplanted zebrafish embryos.

Successful occluder removal and reocclusion of an atrial septal defect after occluder immigration to aortic arch: a case report
Atrial septal defect (ASD) is a common congenital heart disease, and currently, transcatheter intervention is the most common clinical treatment method. However, certain complications still occur during the pe… Read More
Overdiagnosing giant bullous emphysema as metastatic adenocarcinoma: a case report
Giant bullous emphysema is characterized by large bullae occupying at least one-third of the hemithorax and leading to compression of the surrounding lung parenchyma. Overdiagnosis can occur because of the aty… Read More
Type a aortic dissection after aortic wrapping performed 26 years ago: a case report
Aortic wrapping (AW) has been performed as a less invasive alternative to aortoplasty. However, AW can also cause long-term aortic complications. In this report, we present a rare case of a dissecting aortic a… Read More
Left atrioventricular valve regurgitation repair with concomitant outflow obstruction release on repaired atrioventricular septal defect case
Left ventricular outflow tract stenosis and atrioventricular valve regurgitation are often problems encountered in adulthood after complete atrioventricular septal defect repair. The surgical approach and indi… Read More
Pulmonary artery mass with PIK3CA mutation after orthotopic heart transplantation
Patients can develop de novo malignancies following orthotopic heart transplantation. However, vascular tumors are not commonly described in this population.
