Brain tumor-targeted therapy by systemic delivery of siRNA with Transferrin receptor-mediated core-shell nanoparticles
This study aims to investigate the therapeutic effects of intravenous administration of T7 peptide modified core-shell nanoparticles (named T7-LPC/siRNA NPs) on brain tumors. Layer-by-layer assembling of protamine/chondroitin sulfate/siRNA/cationic liposomes followed by T7 peptide modification has been carried out in order to obtain a targeted siRNA delivery system. In vitro cellular uptake experiments demonstrated a higher intracellular fluorescence intensity of siRNA in brain microvascular endothelial cells (BMVECs) and U87 glioma cells when treated with T7-LPC/siRNA NPs compared with PEG-LPC/siRNA NPs. In the co-culture...

Combination Therapy with AKT3 and PI3KCA siRNA Enhances the Antitumor Effect of Temozolomide and Carmustine in T98G Glioblastoma Multiforme Cells
Conclusion The siRNA-induced AKT3 and PI3KCA mRNA knockdown in combination with TMZ and BCNU inhibited proliferation and induced apoptosis and autophagy in T98G cells. Thus, knockdown of these genes in combination with TMZ and BCNU may offer a novel therapeutic strategy to more effectively control the growth of human GBM cells, but further studies are necessary to confirm a positive phenomenon for the treatment of GBM.

The nanoprodrug of polytemozolomide combines with MGMT siRNA to enhance the effect of temozolomide in glioma
Drug Deliv. 2023 Dec;30(1):1-13. doi: 10.1080/10717544.2022.2152911.ABSTRACTTemozolomide (TMZ) is a conventional chemotherapeutic drug for glioma, however, its clinical application and efficacy is severely restricted by its drug resistance properties. O6-methylguanine-DNA methyltransferase (MGMT) is a DNA repair enzyme, which can repair the DNA damage caused by TMZ. A large number of clinical data show that reducing the expression of MGMT can enhance the chemotherapeutic efficacy of TMZ. Therefore, in order to improve the resistance of glioma to TMZ, an angiopep-2 (A2) modified nanoprodrug of polytemozolomide (P(TMZ)n) tha...

Non-canonical Notch Signaling Regulates Actin Remodeling in Cell Migration by Activating PI3K/AKT/Cdc42 Pathway
In conclusion, our research results indicate that DAPT activates PI3K/AKT/Cdc42 signaling by non-canonical Notch pathway, and the activated Cdc42 promotes the filopodia formation and inhibits lamellipodia assembly, resulting in reduced migration of breast cancer cells. The results imply that non-canonical Notch signaling may play a very important role in the rapid response of cells to the extracellular signals. Author Contributions LG, JD, and LL designed the study and wrote and revised the manuscript. LL and LZ performed most of the experiments and data analysis.

Auranofin, an Anti-rheumatic Gold Drug, Aggravates the Radiation-Induced Acute Intestinal Injury in Mice
Conclusion In this study, we found that a non-toxic dose of auranofin significantly aggravated the severity of the radiation-induced intestinal injury. This suggests that auranofin treatment can be an independent factor that influences the risk of intestinal complications after pelvic or abdominal radiotherapy. Ethics Statement All the protocols used in this study were approved by the Institutional Animal Care and Use Committee of the Korean Institute of Radiological and Medical Sciences (IACUC permit number: KIRAMS217-0007). Author Contributions H-JL, JS, and Y-BL designed the experiments. EL and JK conducted the exp...

lncRNA ZEB1-AS1 Mediates Oxidative Low-Density Lipoprotein-Mediated Endothelial Cells Injury by Post-transcriptional Stabilization of NOD2
Conclusion We report the discovery that ZEB1-AS1 functionally participates in ox-LDL-induced ECs injury via LRPPRC-mediated stabilization of NOD2. Uncovering the precise role of ZEB1-AS1/LRPPRC/NOD2 pathway in the progression of ox-LDL-induced ECs death and AS will not only increase our knowledge of ox-LDL-induced AS, but also enable the development of novel therapeutic strategies to overcome oxidation product-induced diseases. Author Contributions XX and CL designed and mainly did the study. CM, ZD, and YD helped and did the study. Conflict of Interest Statement The authors declare that the research was conducted in ...

Delivery of Small Interfering RNA to Inhibit Vascular Endothelial Growth Factor in Zebrafish Using Natural Brain Endothelia Cell-Secreted Exosome Nanovesicles for the Treatment of Brain Cancer
In this study, we tested whether brain endothelial cell-derived exosomes could deliver siRNA across the blood –brain barrier (BBB) in zebrafish. Natural exosomes were isolated from brain endothelial bEND.3 cell culture media and vascular endothelial growth factor (VEGF) siRNA was loaded in exosomes with the assistance of a transfection reagent. While fluorescence-activated cell flow cytometry and immunocy tochemistry staining studies indicated that wild-type exosomes significantly increased the uptake of fluorescence-labeled siRNA in the autologous brain endothelial cells, decreased fluorescence intensity was observed in...

Influences of LncRNA SNHG20 on proliferation and apoptosis of glioma cells through regulating the PTEN/PI3K/AKT signaling pathway.
CONCLUSIONS: Inhibiting the SNHG20 expression in glioma cells can increase the apoptosis of glioma cells, and the mechanism may be related to the SNHG20-mediated PTEN/PI3K/AKT signaling pathway. PMID: 30657567 [PubMed - in process]

Long non-coding RNA H19 regulates the development of gliomas through the Wnt/ β-catenin signaling pathway.
CONCLUSIONS: H19 was overexpressed in glioma tissues and glioma cell lines. Downregulation of H19 inhibited cell proliferation, invasion, and migration, arrested cell cycle progression in the G0/G1 phase, and induced cell apoptosis by restraining activation of the Wnt/β-catenin signaling pathway in glioma cells. Therefore, H19 is a potential therapeutic target for glioma therapy. PMID: 31173296 [PubMed - in process]

Mig-2 attenuates cisplatin-induced apoptosis of human glioma cells in vitro through AKT/JNK and AKT/p38 signaling pathways.
Conclusion:Mig-2 significantly attenuates the antitumor action of cisplatin against human glioma cells in vitro through AKT/JNK and AKT/p38 signaling pathways. The F3 subdomain of mig-2 is necessary and sufficient for this effect. PMID: 25152024 [PubMed - as supplied by publisher]

MiR-200c and miR-141 inhibit ZEB1 synergistically and suppress glioma cell growth and migration.
CONCLUSIONS: MiR-200c and miR-141 are significantly downregulated in glioma tissues and cell lines and can significantly induce ZEB1 mRNA degradation and suppress ZEB1 protein expression in the cells. ZEB1 is a functional downstream target of miR-200c and miR-141 in inhibiting glioma cell growth and migration. PMID: 27608897 [PubMed - in process]
