Microbial carbon use efficiency (CUE)is defined as the proportion of microbial biomass growth C versus substrate C uptake, and thus provides a useful measure of microbially driven accumulation and loss of soil organic carbon (SOC)[1]. In a recent study published in Nature [2],the authors used a data-driven machinelearning approach to conclude that CUE promotes global SOC storage based on a positive correlation between CUE and SOC content and that, based on sensitivity analysis, CUE is at least four times as important as six other evaluated factors,namely plant C inputs, C input allocation, non-microbial C transfer, substrate decomposability, environmental modifications and vertical transport.

反义寡核苷酸是一类靶向沉默mRNA后抑制蛋白翻译的基因疗法,已在多种疾病治疗中应用,但依然缺乏合适的体内递送载体、存在酶稳定性差及使用剂量高等问题。胰岛素样生长因子1型受体(IGF1R)是一种具有酪氨酸激酶活性的细胞表面受体,在多种恶性肿瘤中异常高表达,通过多种途径介导肿瘤细胞的恶性增殖、迁移及侵袭。本研究设计合成了靶向IGF1R mRNA的反义寡核苷酸(N04),利用中性胞苷脂材DNCA联合胱氨酸骨架阳离子脂材CLD对其进行包载递送,并结合化学修饰策略(PS,2’-OMOE),得到稳定且高效的反义寡核苷酸修饰物新型制剂。制剂粒径理想(151 nm)、大小均一(多分散系数0.18)、呈近电中性(ζ电位-3.9 mV)、可被肝癌细胞(HepG-2、Huh-7)高效摄取,明显沉默靶mRNA、导致细胞S期阻滞、促进细胞凋亡,进而抑制细胞增殖。本研究为抗肝细胞癌新型反义寡核苷酸制剂药物的研发提供了工作基础。
