Project description:Influenza A viruses (IAVs), particularly H1N1, H5N1 and H7N9, pose a substantial threat to public health worldwide. Here, we report that MIR2911, a honeysuckle (HS)-encoded atypical microRNA, directly targets IAVs with a broad spectrum. MIR2911 is highly stable in HS decoction, and continuous drinking or gavage feeding of HS decoction leads to a significant elevation of the MIR2911 level in mouse peripheral blood and lung. Bioinformatics prediction and a luciferase reporter assay showed that MIR2911 could target various IAVs, including H1N1, H5N1 and H7N9. Synthetic MIR2911 significantly inhibited H1N1-encoded PB2 and NS1 protein expression but did not affect mutants in which the MIR2911-binding nucleotide sequences were altered. Synthetic MIR2911, extracted RNA from HS decoction and HS decoction all significantly inhibited H1N1 viral replication and improved viral infection-induced mouse weight loss but did not affect infection with a mutant virus in which the MIR2911-binding nucleotide sequences of PB2 and NS1 were altered. Importantly, the inhibitory effect of HS decoction on viral replication was abolished by an anti-MIR2911 antagomir, indicating that the physiological concentration of MIR2911 in HS decoction could directly and sufficiently suppress H1N1 viral replication. MIR2911 also inhibited H5N1 and H7N9 viral replication in vitro and in vivo. Strikingly, administration of MIR2911 or HS decoction both dramatically reduced mouse mortality caused by H5N1 infection. Our results demonstrate that MIR2911 is the first active component identified in Traditional Chinese Medicine to directly target various IAVs and may represent a novel type of natural product that effectively suppresses viral infection.

Project description:Lonicera japonica Thunb., known as Jin Yin Hua or Japanese honeysuckle, is an herbal medicine in Asian countries. Its flowers have been used as folk medicine for clinical practice or used as food or making healthy beverage for 1500 years in China. To investigate the molecular developmental processes from L. japonica buds to flowers under UV radiation, comparative proteomics analyses of buds and flowers were performed. Fifty-four differential proteins were identified including 42 increased proteins and 12 decreased proteins. The abundance of proteins related to glycolysis, TCA/organic acid transformation, major carbohydrate metabolism, oxidative pentose phosphate, stress, secondary metabolism, hormone, and mitochondrial electron transport were increased during flower opening process under UV radiation. Six metabolites were identified and relatively quantified by LC-MS/MS in L. japonica buds and flowers. The 1,1-diphenyl-2-picrylhydrazyl assay revealed that antioxidant activity of L. japonica buds was better than that of flowers. These results suggest that UV-B radiation could induce the production of endogenous ethylene in L. japonica buds, which facilitate the buds blossom and activate the antioxidant system. Additionally, the higher content of metabolites and antioxidant capability in L. japonica buds indicates that L. japonica buds stage might be the better harvest time compared to the flower.
