Project description:Chromosomal inversions play a fundamental role in evolution and have been shown to be responsible for the epidemiologically important traits in malaria mosquitoes. However, they have never been characterized in the major vector of arboviruses Aedes aegypti because of the poor structure of its polytene chromosomes. In this study, we applied a Hi-C proximity ligation approach to identify chromosomal inversions in 23 recently collected strains of Ae. aegypti from its worldwide distribution, two old laboratory colonies, and Ae. mascarensis.
Project description:The genome of two isogenic lines from Aedes aegypti from Ile Royale, French Guiana, with a marked difference in resistance to deltamethrin was investigated in order to understand the genetic basis of this phenotypic difference. Genomic sequencing was performed both with Illumina short, paired reads and with Minion long reads.
Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).
Primary endpoints: circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).
Project description:Investigation of whole genome gene expression level changes of testes in the meiotic drive system in aedes aegypti during spermatogenesis compared to non drive strain. The meiotic drive system in Aedes aegypti causes the female determining chromosome to fragment during spermatogenesis.
