#PROJECT
PR:PROJECT_TITLE                 	Application of a targeted metabolomic profiling for the delineation of
PR:PROJECT_TITLE                 	mechanisms of autolytic systems in Streptococcus mutans cells under oxidative
PR:PROJECT_TITLE                 	stresses
PR:PROJECT_SUMMARY               	Streptococcus mutans is capable of withstanding a variety of stressors
PR:PROJECT_SUMMARY               	encountered in the oral cavity. The ability to efficiently and rapidly adjust to
PR:PROJECT_SUMMARY               	the changing environment is essential for its pathogenic lifestyle. Oxidative
PR:PROJECT_SUMMARY               	stress is one of the most important environmental variables affecting the
PR:PROJECT_SUMMARY               	pathogenic potential of S. mutans, as high oxygen concentrations disfavor growth
PR:PROJECT_SUMMARY               	of S. mutans and other oral bacteria. In order to fulfill its role as a major
PR:PROJECT_SUMMARY               	constituent of cariogenic oral biofilms and sustain virulence, S. mutans must
PR:PROJECT_SUMMARY               	overcome oxidative stress. Oxidation sensing and response is a complex yet
PR:PROJECT_SUMMARY               	highly-regulated process, particularly because it is cross-regulated with other
PR:PROJECT_SUMMARY               	metabolic pathways, stress responses and virulence physiology. In addition, we
PR:PROJECT_SUMMARY               	previously showed that exposure of S. mutans to oxygen strongly inhibits biofilm
PR:PROJECT_SUMMARY               	formation and alters cell surface biogenesis, possibly through AtlA, a major
PR:PROJECT_SUMMARY               	autolysin of the organism. More recently, we have also shown that S. mutans
PR:PROJECT_SUMMARY               	Cid/Lrg system, potentially mediating cell lysis/death in a programmed fashion,
PR:PROJECT_SUMMARY               	uniquely leads a global readjustment in central metabolism and virulence
PR:PROJECT_SUMMARY               	processes, particularly in coping with oxidative stress. To this end, a targeted
PR:PROJECT_SUMMARY               	metabolomics approach will be employed to understand how these autolytic systems
PR:PROJECT_SUMMARY               	influence the metabolism of S. mutans, ultimately leading to a more complete
PR:PROJECT_SUMMARY               	appreciation of how S. mutans survives and persists in hostile host
PR:PROJECT_SUMMARY               	microenvironment.
