Abstract

OBJECTIVE:
To investigate the influence of oridonin on the killing activity of NK-92 MI cells targeting THP1 and the related mechanism.

METHODS:
The killing activity of NK-92 MI to THP1 before and after oridonin treatment was detected by LDH release assay; the expression of natural killer cell ligands activating receptor D (NKG2D, including MICA, MICB, ULBP1, ULBP2 and ULBP3) was detected by real-time quantitative polymerase chain reaction (qRT-PCR) and Western blot respectively; the expression of cytokine TNF-α, TNF-β and IFN-γ in the co-culture supernatant of NK-92 MI cells and THP1 cells were measured by ELISA.

RESULTS:
The killing efficiency after oridonin treatment at different effector-target ratio (1:1, 5:1, 10:1) was all significantly up-regulated in comparison with that before oridonin treatment (P<0.05). QRT-PCR and Western blot showed that the expressions of mRNA and protein levels of MICB, ULBP1, ULBP2 increased to varying degree (P<0.05), but the expression levels of MICA and ULBP3 were not statistically significant between experimental group and control group (P>0.05). ELISA results indicated that IFN-γ and TNF-β release were significantly increased after oridonin treatment (P<0.05), however, the TNF-α release was not statistically different in comparison with control group (P>0.05).

CONCLUSION:
Oridonin can significantly improve killing efficiency of NK-92 MI on THP1, that might be related with up-regulation of MICB, ULBP1 and ULBP2 expression and promotion of IFN-γ and TNF-β release.

Abstract

Oridonin (ORI) is a natural active ingredient with strong anticancer activity. But its clinical use is restricted due to its poor water solubility, short half-life, and low bioavailability. The aim of this study is to utilize the metal organic framework material MOF-5 to load ORI in order to improve its release characteristics and bioavailability. Herein, MOF-5 was synthesized by the solvothermal method and direct addition method, and characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectrometer (FTIR), Thermogravimetric Analysis (TG), Brunauer-Emmett-Teller (BET), and Dynamic Light Scattering (DLS), respectively. MOF-5 prepared by the optimal synthesis method was selected for drug-loading and in vitro release experiments. HepG2 cells were model cells. MTT assay, 4′,6-diamidino-2-phenylindole (DAPI) staining and Annexin V/PI assay were used to detect the biological safety of blank carriers and the anticancer activity of drug-loaded materials. The results showed that nano-MOF-5 prepared by the direct addition method had complete structure, uniform size and good biocompatibility, and was suitable as an ORI carrier. The drug loading of ORI@MOF-5 was 52.86% ± 0.59%. The sustained release effect was reliable, and the cumulative release rate was about 87% in 60 h. ORI@MOF-5 had significant cytotoxicity (IC50:22.99 μg/mL) and apoptosis effect on HepG2 cells. ORI@MOF-5 is hopeful to become a new anticancer sustained release preparation. MOF-5 has significant potential as a drug carrier material.

Abstract

Oridonin (ORI) is a natural diterpenoid presented in some medicinal plants. The effects of pre-treatments from ORI against MPP+- or kainic acid (KA)-induced damage in nerve growth factor (NGF)-differentiated PC12 cells were investigated. Results showed that pre-treatments of ORI at 0.25-2 μM enhanced the viability and plasma membrane integrity of NGF-differentiated PC12 cells. MPP+ or KA exposure down-regulated Bcl-2 mRNA expression, up-regulated Bax mRNA expression, increased caspase-3 activity and decreased Na+-K+ ATPase activity. ORI pre-treatments at test concentrations reversed these changes. ORI pre-treatments decreased reactive oxygen species production, raised glutathione level, and increased glutathione peroxidase, glutathione reductase and catalase activities in MPP+ or KA treated cells. ORI pre-treatments lowered tumor necrosis factor-alpha, interleukin (IL)-1beta, IL-6 and prostaglandin E2 levels in MPP+ or KA treated cells. ORI also diminished MPP+ or KA induced increase in nuclear factor-κB binding activity. MPP+ exposure suppressed tyrosine hydroxylase (TH) mRNA expression and decreased dopamine content. KA exposure reduced glutamine synthetase (GS) mRNA expression, raised glutamate level and lowered glutamine level. ORI pre-treatments at 0.5-2 μM up-regulated mRNA expression of TH and GS, restored DA and glutamine content. These findings suggested that oridonin was a potent neuro-protective agent against Parkinson’s disease and seizure.
