Characterization of Su48, a centrosome protein essential for cell division

The centrosome functions as the major microtubule-organizing center and plays a vital role in guiding chromosome segregation during mitosis. Centrosome abnormalities are frequently seen in a variety of cancers, suggesting that dysfunction of this organelle may contribute to malignant transformation. In our efforts to identify the protein components of the centrosome and to understand the structure features involved in the assembly and functions of this organelle, we cloned and characterized a centrosome-associated protein called Su48. We found that a coiled coil-containing subdomain of Su48 was both sufficient and required for its centrosome localization. In addition, this structure also modulates Su48 dimerization. Moreover, ectopic expression of Su48 causes abnormal mitosis, and a mutant form of Su48 disrupts the localization of gamma-tubulin to the centrosome. Finally, by microinjection of an anti-Su48 antibody, we found that disruption of normal Su48 functions leads to mitotic failure, possibly due to centrosome defects or incomplete cytokinesis. Thus, Su48 represents a previously unrecognized centrosome protein that is essential for cell division. We speculate that Su48 abnormalities may cause aberrant chromosome segregation and may contribute to aneuploidy and malignant transformation.

miR-206对血管内皮细胞增殖的影响及其机制

目的研究miR-206对血管内皮细胞增殖的影响及其机制,为临床动脉硬化疾病提供新的诊疗方向。方法收集临床病理首次确诊为糖尿病下肢动脉粥样硬化病变的患者病变处动脉内皮组织和正常内皮组织,qPCR检测miR-206的表达;而后通过基础实验研究将HUVEC分为未转染组、miR-206-mimics组和miR-206-inhibitor组,观察转染效率;三组细胞均采用CCK8检测细胞增殖情况,Transwell进行迁移能力评估,流式细胞仪检测细胞周期情况,Western blot检测Cx43表达情况。结果糖尿病动脉硬化患者下肢动脉(均为胫腓动脉)病变处内皮细胞miR-206的mRNA表达较正常组织内皮细胞明显增加(P0.05);HUVEC转染miR-206-mimics后,miR-206表达显著升高(P0.05),转染miR-206-inhibitor后,miR-206表达明显降低(P0.05);在HUVEC转染miR-206-mimics 24 h后,细胞增殖率相比于未转染组和miR-206-inhibitor组要明显降低(P0.05);在HUVEC转染miR-206-mimics后,细胞迁移能力明显降低(P0.05),细胞周期在G2期发生阻滞,而HUVEC转染miR-206-inhibitor后细胞迁移能力提高(P0.05);miR-206-mimics组细胞Cx43表达明显降低,而miR-206-inhibitor组细胞Cx43表达明显增加。结论 miR-206可以抑制血管内皮细胞的增殖,将内皮细胞阻滞在有丝分裂G2期,并且抑制内皮细胞迁移,其对内皮细胞增殖的影响可能是通过调节Cx43表达来实现的。

History and Current Status of Development and Use of Viral Insecticides in China

The use of insect viruses as biological control agents started in the early 1960s in China. To date, more than 32 viruses have been used to control insect pests in agriculture, forestry, pastures, and domestic gardens in China. In 2014, 57 products from 11 viruses were authorized as commercial viral insecticides by the Ministry of Agriculture of China. Approximately 1600 tons of viral insecticidal formulations have been produced annually in recent years, accounting for about 0.2% of the total insecticide output of China. The development and use of Helicoverpa armigera nucleopolyhedrovirus, Mamestra brassicae nucleopolyhedrovirus, Spodoptera litura nucleopolyhedrovirus, and Periplaneta fuliginosa densovirus are discussed as case studies. Additionally, some baculoviruses have been genetically modified to improve their killing rate, infectivity, and ultraviolet resistance. In this context, the biosafety assessment of a genetically modified Helicoverpa armigera nucleopolyhedrovirus is discussed.
