Insights into the Temporal Gene Expression Pattern in Lymantria dispar Larvae During the Baculovirus Induced Hyperactive Stage

引用

Virologica Sinica 2018年第4期33卷 345-358页

Baculoviruses are effective biological control agents for many insect pests. They not only efficiently challenge the host immune system but also make them hyperactive for better virus dispersal. Some investigations have focused on the viral mechanisms for induction of such altered response from the host. However, there are no current studies monitoring changes in gene expression during this altered phenotype in infected larvae. The L. dispar multiple nucleopolyhedrovirus(Ld MNPV) induces hyperactivity in third instar L. dispar larvae at 3-days post infection(dpi), to continued till 6 dpi. The transcriptome profiles of the infected and uninfected larvae at these time points were analyzed to provide new clues on the response of the larvae towards infection during hyperactivity. Gene ontology enrichment analysis revealed, most of the differentially expressed genes(DEGs) were involved in proteolysis, extracellular region, and serine-type endopeptidase activity. Similarly, Kyoto Encyclopedia of Genes and Genome enrichment analysis showed maximum enrichment of 487 genes of the signal transduction category and neuroactive ligand–receptor interaction sub-category with 85 annotated genes. In addition, enrichment map visualization of gene set enrichment analysis showed the coordinated response of neuroactive ligand–receptor interaction genes with other functional gene sets, as an important signal transduction mechanism during the hyperactive stage. Interestingly all the DEGs in neuroactive ligand–receptor interactions were serine proteases, their differential expression during the hyperactive stage correlated with their conceivable involvement in disease progression and the resulting altered phenotype during this period. The outcome provides a basic understanding of L. dispar larval responses to Ld MNPV infection during the hyperactive stage and helps to determine the important host factors involved in this process.

Understanding auditory neuropathy spectrum disorder： a system- atic review in transgenic mouse models

Auditory neuropathy spectrum disorder is a unique group of hearing dysfunctions characterized by preserved outer hair cell function and abnormal neural conduction of the auditory pathway. However, the pathogenic mechanism underlying this disorder is not clear. We therefore performed a systematic review of genetic mouse models with different gene mutations to provide a valuable tool for better understanding of the process and the possible molecular mechanisms. Of the 18 articles retrieved, nine met the required criteria. All biochemical, histological, and electrophysiological results were recorded for each of the mouse models, as was the transgenic technology. This review provides a summary of different mouse models that may play an important role in the diagnosis and management of auditory neuropathy spectrum disorder in the future.

Research on micro-machines is becoming popular. In this paper, the electric driving behavior of liquid metal columns in confining channel was studied. When the electric field was applied, the liquid metal near the negative electrode became flat, longer. The NaOH electrolyte(1.0 mol/L) could flow from the positive electrode to the negative electrode from a small space above the liquid metal column. Besides, the length and volume of the liquid metal would affect its motion and deformation behavior. Both cylindrical liquid column(R = 5 mm, L = 5 cm) and linear liquid column(R = 5 mm, L = 40 cm) exhibit deformable movements, which are similar to the bionic movements of earthworms. The electrically driven liquid metal in closed systems could provide a theoretical basis for droplet actuation in *** has a very wide application prospect in the field of micro-drive machines.

在线结构光测量系统中,激光光条图像中心准确提取是影响整个测量系统精度的关键因素之一。针对高反光等复杂环境下光学测量中激光光条图像中心提取问题,提出了一种基于多尺度分析的激光光条图像中心高精度定位方法。该方法利用骨骼化图像处理方法确定激光光条图像中心的初值,根据每一个光条中心初值处的光条宽度确定该位置处对应的高斯核均方差σ的初值。对图像进行多尺度卷积,确定最优的σ值,并求得光条亚像素级中心点,最后完成光条链接。结果表明该算法抗噪声能力强,可实现光条宽度变化较大的激光光条图像中心的高精度提取。
