Hypoxia response in C. neoformans in H99, CM092 and CM098


ABSTRACT: (1) The identification of genes that are transcriptionally regulated in response to exposure to hypoxia (~0.2% oxygen) in H99 (WT) and strains CM092 and CM098. (2) The identification of genes that are differentially-regulated in the strain CM093 compared to H99 (WT) Keywords: hypoxia response, comparative transcriptional hybridization 8 cultures for each strain (4 grown in normoxia and 4 grown in hypoxia) are analyzed on 4 microarrays for each strain (normoxia hybridized against hypoxia). Two out of four microarrays contain dye-swaps.

Fungal pathogens of humans require molecular oxygen for several essential biochemical reactions, yet virtually nothing is known about how they adapt to the relatively hypoxic environment of infected tissues. We isolated mutants defective in growth under hypoxic conditions, but normal for growth in normoxic conditions, in Cryptococcus neoformans, the most common cause of fungal meningitis. Two regulatory pathways were identified: one homologous to the mammalian sterol-response element binding pro  ...[more]
