Deoxycholic Acid-Conjugated Polyethylenimine for Delivery of Heme Oxygenase-1 Gene in Rat Ischemic Stroke Model.
    Journal of pharmaceutical sciences, 2017, Volume: 106, Issue:12

    An efficient gene carrier to the brain is required for successful gene therapy of ischemic stroke. In this study, deoxycholic acid-conjugated polyethylenimine (DA-PEI) was synthesized and evaluated as a heme oxygenase-1 (HO-1) gene carrier for ischemic stroke gene therapy. Gel retardation assay and heparin competition assay showed that DA-PEI formed a stable complex with plasmid DNA. In vitro transfection assays with the luciferase gene showed that DA-PEI had higher transfection efficiency than polyethylenimine (25 kDa, PEI25k) and lipofectamine in Neuro2A cells. Furthermore, DA-PEI had less toxicity than lipofectamine. To evaluate the therapeutic effects of the pβ-HO-1/DA-PEI complex, the complex was injected locally in the brain of the transient middle cerebral artery occlusion animal model. In in vivo studies, DA-PEI was more effective than PEI25k in delivering pβ-HO-1 to the ischemic brain and achieved higher HO-1 expression. As a result, the pβ-HO-1/DA-PEI complexes more effectively reduced infarct volume and the number of apoptotic cells compared with the pβ-HO-1/PEI25k complex. The results suggest that DA-PEI will be useful for HO-1 gene therapy of ischemic stroke.

Synergism and rules from combination of Baicalin, Jasminoidin and Desoxycholic acid in refined Qing Kai Ling for treat ischemic stroke mice model.
    PloS one, 2012, Volume: 7, Issue:9

    Refined Qing-Kai-Ling (QKL), a modified Chinese medicine, consists of three main ingredients (Baicalin, Jasminoidin and Desoxycholic acid), plays a synergistic effect on the treatment of the acute stage of ischemic stroke. However, the rules of the combination and synergism are still unknown. Based on the ischemic stroke mice model, all different kinds of combination of Baicalin, Jasminoidin, and Desoxycholic acid were investigated by the methods of neurological examination, microarray, and genomics analysis. As a result, it confirmed that the combination of three drugs offered a better therapeutical effect on ischemic stroke than monotherapy of each drug. Additionally, we used Ingenuity pathway Analysis (IPA) and principal component analysis (PCA) to extract the dominant information of expression changes in 373 ischemia-related genes. The results suggested that 5 principal components (PC1-5) could account for more than 95% energy in the gene data. Moreover, 3 clusters (PC1, PC2+PC5, and PC3+PC4) were addressed with cluster analysis. Furthermore, we matched PCs on the drug-target networks, the findings demonstrated that Baicalin related with PC1 that played the leading role in the combination; Jasminoidin related with PC2+PC5 that played a compensatory role; while Desoxycholic acid had the least performance alone which could relate with PC3+PC4 that played a compatible role. These manifestations were accorded with the principle of herbal formulae of Traditional Chinese Medicine (TCM), emperor-minister-adjuvant-courier. In conclusion, we firstly provided scientific evidence to the classic theory of TCM formulae, an initiating holistic viewpoint of combination therapy of TCM. This study also illustrated that PCA might be an applicable method to analyze the complicated data of drug combination.
