Gene Regulation and Signal Transduction

Researchers in this area are focused on signaling and transcriptional responses of cells to their environment and to microbial pathogens. Project examples include glucose-induced kinase responses in yeast, transcriptional responses of macrophages to cytokines and inflammation, Toll-like receptors and the innate immune response, and regulation of herpesvirus gene expresion.

DeLuca Lab 

Repression and activation of persisting HSV genomes: Herpes simplex virus can undergo either a productive infection, where all the viral genes are expressed culminating in the production of progeny virus and cell death, or it can enter a latent state, which is characterized by the relative lack of viral gene expression, genome persistence, and cell survival.

Lee Lab

Our lab is studying the RNA-RNA based recruitment mechanism utilized in EBV in greater detail with the goal to extrapolate our findings to the host cell. Since viruses often adopt existing mechanisms from their hosts, our observation suggests that cellular ncRNAs might exist that use RNA-RNA interactions to guide transcription factors to their target sites.

Khan Lab

We are involved in three main areas of research. The first one deals with the role of microRNAs in human papillomavirus-associated cervical and oral cancers as well as role of miRNAs in aging. The second area deals with the cellular functions and mechanism of action of the PcrA helicase which is specifically found in Gram-positive bacteria. The third area of our interest deals with a molecular analysis of the role of the RepX protein in the replication and segregation of the anthrax toxin-encoding pXO1 plasmid in Bacillus anthracis.

Sarkar Lab

Innate immunity of an organism is the inborn protection against invading pathogens. Because it is inborn, and entrusted with the protection of host from a vast array of previously unknown invaders, the innate immune system generates a generalized alert response upon pathogen detection. This alert is chemically mediated by a class of molecules called Cytokines. Learn more>

Schmidt Lab

My lab studies the Snf1 kinase of yeast. The mammalian homologue of Snf1 is the AMP-activated protein kinase, an important therapeutic target for type II diabetes. Biochemical and genetic experiments have shown that Snf1 kinase is regulated by phosphorylation of the conserved threonine residue in the kinase activation loop. Learn more>

Xiao-Qu Lab

Our primary research interests include the study of signaling transduction pathways in immunity and tumorigenesis, particularly NF-kB, as well as the molecular mechanisms underlying the type-1 human T cell leukemia virus (HTLV-I) mediated T cell transformation for disease prevention and therapeutic purposes.
