Our laboratory investigates the impact of gene regulation in health and disease. We work in both yeast (Cryptococcus) and in mammalian cells. The laboratory is located in Genentech Hall at the UCSF Mission Bay Campus. Specific areas of current interest are listed below.
Causes and consequences of gene silencing
We study how information in DNA is controlled. We are particularly interested in the nucleosome because it is the fundamental unit of chromatin, the form of DNA that exists in the nucleus. Modifications of the nucleosome, some of which are heritable, enable the specialization of chromosomal regions for their functions. Defects in these mechanisms underlie numerous diseases including cancer. Key mechanisms under study include the two conserved forms of heterochromatin (H3K9me and H3K27me), DNA methylation (5mC), and RNAi. We seek answers to the fundamental questions of how domains are chosen for silencing, its mechanistic underpinnings, and its biological impact. We use powerful yeast systems (Schizosaccharomyces pombe and Cryptococcus neoformans) that have maintained these mechanisms to address key unanswered questions. For more information click here.
Fungal infections are among the most difficult to diagnose and treat clinically. The yeast Cryptococcus neoformans a leading cause of lethal fungal infections, particularly in immunocompromised individuals. The Madhani Lab has extensively developed this yeast as a powerful model organism enabling studies of the mechanisms underlying fungal pathogenesis and drug responses.
