In 2022,Wang, Yao; Hou, Mengying; Duan, Shanzhou; Zhao, Ziyin; Wu, Xuejie; Chen, Yongbing; Yin, Lichen published an article in Bioactive Materials. The title of the article was ãMacrophage-targeting gene silencing orchestrates myocardial microenvironment remodeling toward the anti-inflammatory treatment of ischemia-reperfusion (IR) injuryã?Related Products of 13325-10-5 The author mentioned the following in the article:
Ischemia-reperfusion (IR) injury represents a major cause of myocardial dysfunction after infarction and thrombolytic therapy, and it is closely related to the free radical explosion and overwhelming inflammatory responses. Herein, macrophage-targeting nanocomplexes (NCs) are developed to mediate efficient co-delivery of siRNA against MOF (siMOF) and microRNA-21 (miR21) into myocardial macrophages, cooperatively orchestrating the myocardial microenvironment against IR injury. Bioreducible, branched poly(β-amino ester) (BPAE-SS) is designed to co-condense siMOF and miR21 into NCs in a multivalency-reinforced approach, and they are surface-decorated with carboxylated mannan (Man-COOH) to shield the pos. surface charges and enhance the serum stability. The final MBSsm NCs are efficiently internalized by myocardial macrophages after systemic administration, wherein BPAE-SS is degraded into small segments by intracellular glutathione to promote the siMOF/miR21 release, finally provoking efficient gene silencing. Thus, cardiomyocyte protection and macrophage modulation are realized via the combined effects of ROS scavenging, inflammation inhibition, and autophagy attenuation, which ameliorates the myocardial microenvironment and restores the cardiac function via pos. cellular crosstalk. This study renders promising solutions to address the multiple systemic barriers against in vivo nucleic acid delivery, and it also offers new options for IR injury by manipulating multiple reciprocal bio-reactions.4-Aminobutan-1-ol(cas: 13325-10-5Related Products of 13325-10-5) was used in this study.
4-Aminobutan-1-ol(cas: 13325-10-5) is used in the synthesis of NSAIDs with anti-inflammatory properties. Also used in the synthesis of polyamine transport ligands with specificity against human cancers allowing easy access to specific cancer cells.Related Products of 13325-10-5
