Global Genomic Analysis of Candida albicans Transcription Profiles, Genome Stability, and Centromere Function

This group studies the human pathogenic fungus Candida albicans. They analyze global patterns within large sets of transcription profiles and also analyze the DNA content of clinical and laboratory strains that have undergone genome changes using Comparative Genome Hybridization (CGH). CGH has revealed a number of aneuploidies in strains, and especially in strains resistant to specific anti-fungal drugs. In addition, the Berman lab discovered that centromeres, the chromosome regions responsible for segregation to both daughter cells, can move long distances within a chromosome to form "neocentromeres.” They are using chromatin immunoprecipitation coupled with massively parallel sequencing to analyze the DNA positions of neocentromeres. They then develop models for the sequence components that contribute to centromere/neocentromere positioning.
