Solid tumors are difficult to surgically remove and often do not respond to radiation and chemotherapy. This study fabricated ginsenoside Rg3 nanoparticles and evaluated their antitumor effect in mice. The results showed that Rg3-NPs were more effective than regular Rg3 in reducing tumor weight and size, and the effect was dose-dependent. The fabrication of Rg3-NPs enhanced the protective effect against tumor development.
Solid tumors are fairly common and face many clinical difficulties since they are hardly surgically resectable and broadly do not respond to radiation and chemotherapy. The current study aimed to fabricate ginsenoside Rg3 nanoparticles (Rg3-NPs) and evaluate their antitumor effect against Ehrlich solid tumors (EST) in mice. Rg3-NPs were fabricated using whey protein isolates (WPI), maltodextrin (MD), and gum Arabic (GA). EST was developed by the injection of mice with Ehrlich ascites cells (2.5 x 10(6)). The mice were divided into a control group, EST group, and the EST groups that were treated orally 2 weeks for with normal Rg3 (3 mg/kg b.w.), Rg3-NPs at a low dose (3 mg/kg b.w.), and Rg3-NPs at a high dose (6 mg/kg b.w.). Serum and solid tumors were collected for different assays. The results revealed that synthesized Rg3-NPs showed a spherical shape with an average particle size of 20 nm and zeta potential of -5.58 mV. The in vivo study revealed that EST mice showed a significant increase in AFP, Casp3, TNF-alpha, MMP-9, VEGF, MDA, and DNA damage accompanied by a significant decrease in SOD and GPx. Treatment with Rg3 or Rg3-NPs decreased the tumor weight and size and induced a significant improvement in all the biochemical parameters. Rg3-NPs were more effective than Rg3, and the improvement was dose-dependent. It could be concluded that fabrication of Rg3-NPs enhanced the protective effect against EST development which may be due to the synergistic effect of Rg3 and MD, GA, and WPI.
