A Mechanistic and Functional Study of White opaque Phenotypic Switching in Candida Albicans Book Review:

Candida albicans is a major fungal pathogen of humans. It is a harmless commensal in healthy individuals, but it can cause serious infections in immune-compromised hosts. C. albicans undergoes a meta-stable and reversible switch between two distinct cell types known as white and opaque. The role of white-opaque switching in the biology of C. albicans was originally not well understood. We discovered an unexpected relationship between white-opaque switching and the sexual cycle of C. albicans . The mating type locus of C. albicans (MTL) encodes transcriptional regulatory proteins that regulate mating. We demonstrated that two MTL -encoded homeodomain proteins, a 1 and alpha2, work together to repress white-opaque switching in C. albicans . The observations that the MTL locus controlled both mating and white-opaque switching led us to hypothesize that opaque cells played a role in mating. Indeed, we found that opaque cells mate one million times more efficiently than do white cells. Additionally, opaque cells, but not white cells, developed specialized mating projections when exposed to mating pheromone. Thus, opaque cells are a specialized mating form of C. albicans . As white cells are generally more robust in a mammalian host than opaque cells, this strategy allows the organism to survive the rigors of life within a mammalian host, while generating a small population of mating-competent cells. The mechanism that controls white-opaque switching is not well understood. To better understand the mechanism, we investigated the regulation of white-opaque switching by a 1-alpha2. We demonstrated that a 1-alpha2 regulates white-opaque switching by destabilizing opaque cells, and we monitored gene expression during the transition from opaque to white using DNA microarrays. We used a candidate approach to identify additional regulators of white-opaque switching among genes enriched for their expression in the opaque phase. We identified two potent positive regulators of white-opaque switching: the opaque-specific transcriptional regulatory proteins Czf1 and Naf1. We also further investigated the role of Efg1, a previously identified regulator of white-opaque switching, and found that efg1/efg1 mutants were unable to bypass a 1-alpha2 repression of switching. Finally, we determined the epistatic and regulatory relationships between Efg1, Czf1 and Naf1.

Candida Albicans Phenotypic Switching and Functional Plasticity in the Mammalian Host Book Review:

In order to determine the host signals and fungal signaling pathways that control the white-GUT switch and drive commensalism, we developed an in vitro system to induce switching behavior and screened a library of C. albicans signaling mutants. We identified three fungal signaling pathways (Hog1, Rim101, and PKA), previously associated with other morphological transitions, which promote GUT cell formation. Together these studies help to understand how C. albicans' phenotypic plasticity influences its interactions with the mammalian host.

Marsh and Martin s Oral Microbiology E Book Book Review:

Now expanded with the latest information of relevance to current dental practice, Oral Microbiology retains its unique ecological approach to the subject which helps the reader determine whether an organism will have a pathogenic or commensal relationship at a given site. In the new edition, greater emphasis is placed on the role of current molecular biology techniques in the understanding of oral microbes. The book also provides insight into current therapeutic and prophylactic antibiotic use, infection control, and the relationships between oral and general health. Oral Microbiology provides comprehensive coverage of the subject which will be essential to readers with a specific interest in dentistry as well as those with a more general interest in host-microbe interactions and in microbial ecology. The book is suitable for undergraduate and postgraduate dental students, research workers, and a wide range of clinical dental professionals. Full coverage of the latest molecular biology techniques which have revolutionized our knowledge of oral microbes Exploration of the biological and clinical significance of the oral microflora in the form of a biofilm on dental and mucosal surfaces Contemporary views on therapeutic and prophylactic antibiotic use, infection control, and the relationships between oral and general health

Interactions Between Phenotypic Switching Gene Network Dynamics and Evolutionary Dynamics in Growing Cell Populations Book Review:

Gene expression is a stochastic biological processes that controls the different phenotypes of an organism depending on the environment. High-resolution single cell measurements show that genetically identical cells can be different from each other even in a homogeneous environment, leading a spectrum of phenotypes with different cellular fitnesses that can reversibly switch between phenotypes. How population-level properties emerge from single cell behavior and how mutants emerge and spread in such populations is unclear. In this thesis, we developed mathematical models to study (i) the effect of time-delay needed for a mutation in a regulator gene influence an effector protein and the long term population fitness, (ii) how optimum population fitness behaves as a function of the growth rates of the various phenotypes for different durations in fluctuating environments. Our work shows a paradoxical outcome of evolution where mutations in a regulator gene interact with gene network dynamics and evolutionary dynamics, giving rise to permanent decrease in population fitness. In the other scenario of fluctuating environments, a previously predicted optimum exists for wider parameter regime if the environmental durations are long and narrow regime for short environmental durations. We also find that a mutant, which randomly evolved to match its phenotypic switching rates with environmental switching rates, can sweep the population if the predicted optimum matches with the assumed one, but not otherwise.
