Yolanda Huang

Undergrad Education: Pennsylvania State University
Degree / Year: BA Wellesley College/ 2003
Mentor(s): Mohanish Deshmukh

Current Research Activities (brief description):
Our lab is interested in examining the regulation of the apoptotic pathway in postmitotic cells. My project is based upon previous findings that XIAP, a key anti-apoptotic molecule which inhibits caspases, is important in restricting neuronal death in sympathetic neurons. We, therefore, hypothesize that mice deficient of XIAP will be more vulnerable to neurological diseases.

Undergrad Education: Pennsylvania State University
Degree / Year: BS Biochemistry and Molecular Biology / 2001
Mentor(s): Vytas Bankaitis

Current Research Activities (brief description):
The Bankaitis lab’s interest is phosphatidylinositol transfer proteins. PITPs are a ubiquitous family of proteins with roles that include regulating the interface between lipid levels and vesicle transport. I am focusing on PITPb, a mammalian homologue that is essential for mouse development, and may be an essential housekeeping protein. My project is to determine what is responsible for the functional distinction of PITPb from its close homologue PITPa, and to examine what happens to cells and organisms when PITPb is lost.

Terezina (Zina) Johnson

Undergrad Education: University of Illinois at Chicago
Degree / Year: BS Biological Sciences / 2001
Mentor(s): Con Beckers

Current Research Activities (brief description):
The research in our laboratory revolves around the human protozoan parasite Toxoplasma gondii which can cause severe disease in individuals with a defective immune system or during pregnancy. It is used as a model system for study of the closely related malaria parasite, Plasmodium. These parasites contain a large membrane-associated protein complex that contains a myosin required for parasite motility. I am currently analyzing the function and regulation of the four proteins found in this complex.

Current Research Activities (brief description):
I currently am characterizing Coronin 2A, an F-actin binding protein that localizes to stress fibers and focal adhesions. Through the use of shRNA knockdown and GFP fusion overexpression constructs, I am trying to determine the role of Coronin 2A in actin cytoskeleton organization and cell motility.

Current Research Activities (brief description):
MicroRNAs are small non-coding RNAs that regulate gene-expression at the post-transcriptional level. The Hammond Lab recently reported a phenomenon where microRNA expression during development and in cancer seems to be regulated at the post-transcriptional level. I am currently investigating the molecular mechanisms that govern this phenomenon.

Allyson Vaughn

Undergrad Education: University of Missouri-Columbia
Degree / Year: BS / 2002
Mentor(s): Mohanish Deshmukh

Current Research Activities (brief description):
Our lab is working to better understand the mechanisms by which postmitotic cells regulate the programmed cell death pathway and undergo apoptosis. We find that compared to mitotic cells, postmitotic cells more strictly regulate this pathway in order to last the lifetime of the organism. Understanding how this process is regulated differentially between dividing and non-dividing cells is important for developing rational therapies that may prevent cell loss in pathological situations such as stroke, spinal cord injury, and neurodegenerative disease. In particular, I am interested in understanding the mechanisms by which neuronal cells resist apoptosis induced by cytosolic cytochrome c, and how this resistance is overcome in response to both developmental and pathological apoptotic stimuli.

Current Research Activities (brief description):
Our lab studies the role of novel glycolytic isozymes expressed only during spermatogenesis. In mice, localized glycolytic ATP production in the sperm tail is essential for male fertility, suggesting that these isozymes may be useful targets for both the development of contraceptive approaches and treatments of male infertility. My project involves characterizing the enzymatic properties of three novel aldolase A glycolytic isozymes expressed only during mouse spermatogenesis.

Hao Wu

Undergrad Education: Beijing Forestry University
Degree / Year: BS / 2001
Mentor(s): Patrick Brennwald

Current Research Activities (brief description):
Rho3 and Cdc42 are members of the Rho family of small GTPases in Saccharomyces cerevisiae. Both proteins play important but distinct roles in regulating polarized growth in yeast. My research is focused on understanding the mechanism by which Rho small GTPases regulate exocytosis. Genetic analysis has revealed that Rho3 and Cdc42 shares a common effector Exo70. Exo70 adopt a conformational change upon activation of GTP-bound Rho3 and Cdc42, which then leads to activation of the Exocyst complex and secretion.
