ObjectiveTo investigate whether elemene(ELE) enhances the anti-glioma efficacy of cabazitaxel(CTX), and prepare a double-targeted cationic liposome(LIP) co-loaded with ELE/CTX for the treatment of glioma, and to achieve the effect of increasing the efficacy and reducing the adverse reactions. Pharmacodynamic tests in vitro were performed to explore the advantages and mechanism of its preparation. MethodELE/CTX@LIP was prepared by high speed shear combined with probe ultrasound, the particle size and potential were characterized by nano-particle size potentiometer, and high performance liquid chromatography(HPLC) was used to determine the encapsulation efficiency and drug loading capacity of CTX/ELE. The cytotoxicity of ELE/CTX in vitro was detected by cell proliferation and activity assay(CCK8). JMP Pro 16 software was used to optimize the process parameters of ELE/CTX@LIP based on encapsulation efficiency. The optimal cationic material type, content and ratio were screened by in vitro cytotoxicity and in vitro cell uptake, on this basis, the dual-targeted cationic liposome T7/arginine glycine aspartate tripeptide sequence(T7/cRGD)-ELE/CTX@CLIP was prepared, the stability of morphology and particle size were characterized, and the effect of T7/cRGD-ELE/CTX@CLIP on the apoptosis inducing ability and cell cycle regulation ability of glioma cells was analyzed by cell cycle and apoptosis. ResultELE/CTX showed stronger anti-glioma activity on C6 and RG2 cells. The results of in vitro cytotoxicity and in vitro cell uptake showed that the amount of cationic material was 0.10% of the total content. The optimum ratio of T7, cRGD and phospholipids was 1∶1∶50. T7/cRGD-ELE/CTX@CLIP[1,2-dilinoleyloxy-3-dimethylaminopropane(Dlin-MC3-DMA)] and T7/cRGD-ELE/CTX@CLIP[1,2-dimyristoyl-rac-glycero-3-methoxypolyethylene glycol 2000(DMG-PEG2000)] showed multi-level spherical nanostructures with particle sizes of 146.0, 111.3 nm, respectively, and were stable in serum. In vitro cytotoxicity results showed that T7/cRGD-ELE/CTX@CLIP had higher cytotoxicity to glioma cells than single-targeted liposomes or dual-targeted non-cationic liposomes. T7/crGD-ELE/CTX@CLIP affected the apoptosis and cycle of glioma cells, the results showed that ELE/CTX combined with liposomes could more effectively activate the apoptosis channel and inhibit the proliferation of glioma cells, and the use of T7/cRGD short peptide and cation modification enhanced the ability of apoptosis induction. ELE/CTX could effectively block glioma cell cycle at G2/M phase, and the effect was enhanced after T7/cRGD targeted modification. ConclusionELE can enhance the anti-glioma effect of CTX. The preparation parameters of ELE/CTX@LIP are stable and feasible. Combined with the in vitro efficacy test, the anti-glioma mechanism of T7/cRGD-ELE/CTX@CLIP is preliminarily revealed.

[Abstract] Objective: To quantify the expression of growth arrest and DNA damage inducible protein 45g (GADD45g) gene in the bone marrow samples of patients withAML (acute myeloid leukemia) and inAML cell lines, as well as to study the correlation between the GADD45g expression and prognostic outcome in patients withAML and investigate the role of GADD45g over-expression in proliferation, apoptosis, senescence, differentiation, cell cycle arrest, and drug sensitivity in AML cell lines. Methods: In the study, a total of 27 cases of bone marrow specimens were selected from patients initially diagnosed as AML in Hospital of Blood Diseases affiliated to Chinese Academy of Medical Sciences from January 2013 to December 2016. mRNA and protein expression levels of GADD45g in BMMNCs (Bone marrow mononuclear cells) from patients with AML and healthy donors and in AML cell lines were quantified by quantitative real-time PCR and Western blotting. The correlation between GADD45g expression and overall survival (OS), coupled with event-free survival (EFS) in patients with AML was analyzed in two gene expression datasets (GSE10358, GSE425-GPL317). Lentiviral vectors over-expressing GADD45g were constructed and transfected into AML cell lines (U937, THP-1 and Molm-13 cell lines). The role of GADD45g over-expression in cell proliferation, colony formation, senescence, apoptosis, cell cycle arrest, differentiation and drug sensitivity of U937, THP-1 and Molm-13 cells were detected by cell counting, colony-forming assay, β-galactosidase staining and flow cytometric analysis of Annexin V/7AAD staining, PI staining and so on, respectively. Results: Expression of GADD45g was dramatically down-regulated in BMMNCs in AML patients and AML cell lines compared to that from healthy donors (all P<0.01). The OS (P<0.05) and EFS (P<0.05) of AML patients with low GADD45g expression were significantly shorter that those of AML patients with higher GADD45g level. Enforced expression of GADD45g could inhibit cell growth and colony formation, promote senescence and apoptosis, induce cell cycle arrest and differentiation and enhance drug sensitivity in AML cell lines (P<0.05 or P<0.01). Conclusion: GADD45g expression was remarkably silenced in marrow tissues of patients withAML andAML cell lines; it showed remarkable and all-around inhibiting effect onAMLcell lines, indicating that GADD45g expression has prognostic value inAML.
