Cancer is a disease subject to both genetic and environmental influences. In this study, we used the RIP1-Tag2 (RT2) mouse model of islet cell carcinogenesis to identify a genetic locus that influences tumor progression to an invasive growth state. RT2 mic ...
Comparative genomics, and related technologies, are helping to unravel the molecular basis of the pathogenesis, host range, evolution and phenotypic differences of the slow-growing mycobacteria. In the highly conserved Mycobacterium tuberculosis complex, w ...
Metabolic homeostasis is achieved by complex molecular and cellular networks that differ significantly among individuals and are difficult to model with genetically engineered lines of mice optimized to study single gene function. Here, we systematically a ...
When searching for loci possibly under selection in the genome, an alternative to population genetics theoretical models is to establish allele distribution models for each locus to directly correlate allelic frequencies and environmental variables like pr ...
Understanding the genetic basis of species adaptation in the context of global change poses one of the greatest challenges of this century. Although we have begun to understand the molecular basis of adaptation in those species for which whole genome seque ...
To evaluate the contribution of genetic background to phenotypic variation, we compared a large range of biochemical and metabolic parameters at different ages of four inbred mice strains, C57BL/6J, 129SvPas, C3HeB/FeJ, and Balb/cByJ. Our results demonstra ...
The efficiency of social insect colonies critically depends on their ability to efficiently allocate workers to the various tasks which need to be performed. While numerous models have investigated the mechanisms allowing an efficient colony response to ex ...
As the focus of human genetics shifts from Mendelian traits to complex diseases, a sophisticated genetic tool kit—with space for genetics (classical, molecular, statistical, and quantitative), metabolics, proteomics, bioinformatics, and mathematics—is requ ...
Mice carrying transgenes targeted upstream the HoxD cluster display abnormal digits, with alterations resembling those obtained with loss of functions of Hoxd genes. Because the HoxD cluster remained entirely untouched by the insertional events, we investi ...
Conditionally immortalized human cells are valuable substrates for basic biologic studies, as well as for the production of specific proteins and for the creation of bioartificial organs. We previously demonstrated that the lentivector-mediated transductio ...
