| 1 | Plant-derived phosphocholine facilitates cellular uptake of anti-pulmonary fibrotic HJT-sRNA-m7显示文摘Pulmonary fibrosis, a progressive chronic disease with a high mortality rate, has limited treatment options. Currently, lung transplantation remains the only effective treatment. Here we report that a small RNA, HJT-sRNA-m7, from a Chinese herbal medicine Hong Jing Tian(HJT, RHODIOHAE CRENULATAE RADIX ET RHIZOMA, Rhodiola crenulata) can effectively reduce the expressions of fibrotic hallmark genes and proteins both in alveolar in vitro and in mouse lung tissues in vivo. We also discovered over one hundred oil-soluble chemicals from HJT decoctions, most of which are found in lipid extracts from other Chinese herbals decoctions, including Pu Gong Ying(PGY, TARAXACI HERBA, Taraxacum mongolicum), Chuan Xin Lian(CXL, changed to 'ANDROGRAPHIS HERBA, Andrographis paniculata'), and Jin Yin Hua(JYH, lonicera japonica or Honeysuckle). We identified the active component in these decoctions as two forms of phosphocholines, PC(18:0/18:2) and PC(16:0/18:2). These PCs potentially could form liposomes with small RNAs to enter human alveolar and gastric cells. Our experimental results suggest an unprecendent lipid complex route through which botanic small RNA can enter human bodies.Our results provide an innovative treatment strategy for oral delivery of siRNAs as therapeutic medication. | Jianchao Du Zhu Liang Jiantao Xu Yan Zhao Xiaoyun Li Yanli Zhang DANDan Zhao Ruxuan Chen Yang Liu Trupti Joshi Jiahui Chang Zhiqing Wang Yanxu Zhang Jindong Zhu Qiang Liu Dong Xu Chengyu Jiang | 2019 | Science China(Life Sciences)2019，62，3： | 21 |
| 2 | 植物来源的磷脂酰胆碱可介导抗肺纤维化小RNA(HJT-sRNA-m7)进入哺乳动物细胞显示文摘肺纤维化是慢性进行性疾病,死亡率高,临床上除肺移植之外尚无其他明显有效治疗手段.本研究发现,来源于中药大花红景天(Rhodiola crenulata)的小RNA,HJT-sRNA-m7,可以显著降低纤维化因子的表达,在细胞和动物水平上均可改善纤维化症状.此外,本研究组在红景天熬制的汤汁中提取鉴定了一百多种脂质,其中大部分脂质也同时存在于中药蒲公英(Taraxacum mongolicum)、穿心莲(Andrographis paniculata)和金银花(lonicera japonica)中.选取其中两种磷脂酰胆碱PC(18:0/18:2)和PC(16:0/18:2),使之与植物小RNA形成脂质体,发现其可促进HJT-s RNA-m7等小RNA进入人肺和胃肠道细胞,降低纤维化靶基因的表达.实验结果揭示了植物来源小RNA通过脂质复合物进入人体的可能途径,为si RNA的临床应用提供了新的口服递送途径. | 杜涧超 梁竹 许剑涛 赵妍 李晓芸 张艳丽 赵丹丹 陈茹萱 刘洋 Trupti Joshi 常佳慧 王志清 张延旭 朱锦东 刘强 许东 蒋澄宇 | 2018 | 中国科学:生命科学2018，48，4： | 4 |
