Breakthrough in Cancer Gene Therapy: Multifunctional Nanomaterials Show Promise
Investigators at the University of Ha'il have made significant advancements in cancer gene therapy, developing a multifunctional nanomaterial that exhibits potential in both antimicrobial and anticancer therapies. The nanostructured lipid carriers (NLCs) encapsulating Bacillus megaterium supernatant (BMS) and magnetic nanoparticles (MNPs) demonstrated remarkable properties, including antibacterial activity, with minimum inhibitory concentrations (MICs) ranging from 7.5 to 30 g/mL. The nanomaterials also displayed significant downregulation of biofilm-associated genes and reduced viability of cancer cells, including HepG2 and MCF-7 cells.
Key Takeaways:
- The novel NLCs were prepared using the emulsification-solvent evaporation technique and loaded with BMS and MNPs to form NLC-BMS-MNPs.
- Characterization of the NLC-BMS-MNPs revealed a spherical morphology with an average size of 74.45 nm and a zeta potential of -4.44 mV.
- The NLC-BMS-MNPs demonstrated antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA) and cancer cells, with MICs ranging from 7.5 to 30 g/mL.
- The nanomaterials significantly downregulated the expression of biofilm-associated genes, with fold changes ranging from -1.9 to -3, -2 to 3, -4 to 5.2, respectively.
- The NLC-BMS-MNPs reduced the viability of HepG2 and MCF-7 cells, with IC values of 13.74 ± 0.02 g/mL and 19.12 ± 0.51 g/mL, respectively, compared to normal Vero and HFB-4 cells.
