Abstract

Anopheles mosquitoes are known as dominant vectors of malaria parasites and other viral and bacterial pathogens. Deciphering Anopheles genomes has opened a new era of research and allowed in-depth investigation of several molecular mechanisms involved in pathogen transmission. However, there is a lack of appropriate model systems to study specific vector-pathogen interactions at the molecular level. Even inbred mosquito colonies represent genetically heterogeneous population and require special care facilities. Insect cell cultures could serve as a useful alternative due to the ease of handling and maintenance, especially for genomic studies requiring millions of cells per experiment. Here, we provide chromatin contact maps and a dataset of epigenetic characteristics, including histone mark profiles and RNA-seq data, as well as transfection conditions and promoter specificity for the mosquito cell line MSQ43.

摘要

按蚊是已知的疟原虫以及其他病毒和细菌病原体的主要传播媒介。对按蚊基因组的破译开启了一个新的研究时代,并使得对参与病原体传播的多种分子机制进行深入研究成为可能。然而,缺乏合适的模型系统来在分子水平上研究特定的媒介-病原体相互作用。即使是近交系蚊群也代表着基因异质群体,并且需要特殊的饲养设施。昆虫细胞培养由于易于操作和维护,可作为一种有用的替代方法,特别是对于每个实验需要数百万个细胞的基因组研究。在这里,我们提供了染色质接触图谱以及表观遗传特征数据集,包括组蛋白标记谱和RNA测序数据,以及蚊虫细胞系MSQ43的转染条件和启动子特异性。
