DataSheet1_A Rapid Evolving microRNA Cluster Rewires Its Target Regulatory Networks in Drosophila.ZIP

New miRNAs are evolutionarily important but their functional evolution remains unclear. Here we report that the evolution of a microRNA cluster, mir-972C rewires its downstream regulatory networks in Drosophila. Genomic analysis reveals that mir-972C originated in the common ancestor of Drosophila where it comprises six old miRNAs. It has subsequently recruited six new members in the melanogaster subgroup after evolving for at least 50 million years. Both the young and the old mir-972C members evolved rapidly in seed and non-seed regions. Combining target prediction and cell transfection experiments, we found that the seed and non-seed changes in individual mir-972C members cause extensive target divergence among D. melanogaster, D. simulans, and D. virilis, consistent with the functional evolution of mir-972C reported recently. Intriguingly, the target pool of the cluster as a whole remains relatively conserved. Our results suggest that clustering of young and old miRNAs broadens the target repertoires by acquiring new targets without losing many old ones. This may facilitate the establishment of new miRNAs in existing regulatory networks.</p

Solvent Induced Diverse Dimensional Coordination Assemblies of Cupric Benzotriazole-5-carboxylate: Syntheses, Crystal Structures, and Magnetic Properties

Three cupric coordination assemblies [Cu(btca)(H2O)2] (1), [Cu(btca)(H2O)3.5]8·16H2O (2), and [Cu2.5(btca)1.5(Hbtca)0.5(μ-Cl)0.5(μ3–OH)(H2O)]·H2O (3) have been solvothermally synthesized by cupric salts and a bifunctional ligand benzotriazole-5-carboxylic acid (H2btca) in different solvent medium. These complexes were structurally characterized by X-ray diffraction analyses and further identified by infrared spectra (IR), elemental analyses, powder X-ray diffraction (PXRD), and thermogravimetric analyses (TGA). Single crystal structural analysis shows that these coordination compounds assembled by the almost same reactants present diverse dimensional crystal structures, wherein 1 possesses two-dimensional (2D) layers with (4.82) topology, the zero-dimensional (0D) neutral metallomacrocycle with flat octagonal geometry in 2 connects each other through hydrogen bonding to extend to be a three-dimensional (3D) nanotubular network, and 3 exhibits 3D framework with 1D honeycomb channels constructed by the strip-shaped chains containing [Cu5(μ3-OH)2(btca)4]− pentaclusters bridging to the adjacent Cu6(btca)126‑ cages. The diversity of these structures mainly stems from the versatile coordination modes of the anionic ligand in each compound, especially the 1,2,3-triazolate group: bidentate μ1,2 bridging mode in 1, bidentate μ1,3 bridging mode in 2, and tridentate μ1,2,3 bridging mode in 3, respectively. Furthermore, the magnetic properties of 1–3 have been investigated as well

Palladium- and Nickel-Catalyzed Kumada Cross-Coupling Reactions of <i>gem</i>-Difluoroalkenes and Monofluoroalkenes with Grignard Reagents

A novel Kumada–Tamao–Corriu cross-coupling reaction of gem-di- or monofluoroalkenes with Grignard reagents, with or without β-hydrogen atoms, in the presence of a catalytic amount of palladium- or nickel-based catalysts has been developed. The reaction is performed under mild conditions (room temperature or reflux in diethyl ether for 1–2 h) and leads to di-cross- or mono-cross-coupled products in good to high yields
