Abstract
This study discussed Astragalus Polysaccharides (APS)’s effect on the cytobiology of glioma. U87 glioma cells were assigned into control group (U87 cells), miR-34a-5p mimic group (transfected with miR-34a-5p mimic), and APS group (treated with 10 μM APS) followed by
analysis of miR-34a-5p level, cell proliferation and invasion, Caspase3 and SOD activity as well as E-cadherin, Vimentin and survivn expression. APS treatment significantly upregulated miR-34a-5p expression, inhibits cell proliferation and invasion, and promoted cell apoptosis. In addition,
APS also significantly upregulated E-cadherin, downregulated Vimentin and survivn level in glioma cells as well as inhibited ROS generation and increased SOD activity. In conclusion, the level of miR-34a-5a in glioma cells is up-regulated by APS so as to restrain the biological behaviors of
glioma cells, indicating that it might be used as novel agent for the treatment of glioma.

Adv Drug Deliv Rev 2022; 185:114303. [PMID: 35460714 DOI: 10.1016/j.addr.2022.114303] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 04/09/2022] [Accepted: 04/12/2022] [Indexed: 12/14/2022]
Abstract
Even though the last decade has seen a surge in the identification of molecular targets and targeted therapies in pediatric brain tumors, the blood brain barrier (BBB) remains a significant challenge in systemic drug delivery. This continues to undermine therapeutic efficacy. Recent efforts have identified several strategies that can facilitate enhanced drug delivery into pediatric brain tumors. These include invasive methods such as intra-arterial, intrathecal, and convection enhanced delivery and non-invasive technologies that allow for transient access across the BBB, including focused ultrasound and nanotechnology. This review discusses current strategies that are being used to enhance delivery of different therapies across the BBB to the tumor site - a major unmet need in pediatric neuro-oncology.
