Dr. Cheung's major research interests are regulation of virulence gene in Staphylococcus aureus, a major human pathogen both in the community and in hospital settings. My lab has four separate but related directions: 1) regulation of virulence determinants by global regulatory in S. aureus; 2) expression of virulence genes in vivo; 3) development of novel targets for antimicrobial therapy; 4) role of sRNA in virulence in S. aureus.
YpdA, a putative bacillithiol disulfide reductase, contributes to cellular redox homeostasis and virulence in Staphylococcus aureus.
Role of Purine Biosynthesis in Persistent Methicillin-Resistant Staphylococcus aureus Infection.
Small RNA teg49 Is Derived from a <i>sarA</i> Transcript and Regulates Virulence Genes Independent of SarA in Staphylococcus aureus.
α-Toxin Regulates Local Granulocyte Expansion from Hematopoietic Stem and Progenitor Cells in <i>Staphylococcus aureus-</i>Infected Wounds.
A quinolinol-based small molecule with anti-MRSA activity that targets bacterial membrane and promotes fermentative metabolism.
Bypassing the restriction system to improve transformation of <i>Staphylococcus epidermidis</i>.
Persister formation in Staphylococcus aureus is associated with ATP depletion.
The Global Regulon sarA Regulates β-Lactam Antibiotic Resistance in Methicillin-Resistant Staphylococcus aureus In Vitro and in Endovascular Infections.
Persister formation in <i>Staphylococcus aureus</i> is associated with ATP depletion.
