Wenqing Cai
wenqingc@burnham.org
Program: Molecular Medicine
Advisor: Dr. Mark Mercola
Year entered program: 2007
Research Focus
Wenqing Cai is focusing on natural inducers of heart differentiation in embryonic stem cells. Heart attacks and congestive heart failure remain among most prominent health challenges in the world. However, despite successful approaches to prevent or limit cardiovascular disease, the restoration of function to the damaged heart remains a formidable challenge. Stem cell biology represents a new approach of regenerative medicine, and Wenqing is working toward using embryonic stem cells to replace damaged cardiomyocytes and restore cardiac function.

Dietary restriction, or limited food intake without malnutrition, is known to extend the lifespan of many organisms. However, the cellular mechanisms underlying this fascinating phenomenon are still poorly understood. Using the nematode C. elegans Sara is working to address how autophagy promotes C. elegans longevity at the cellular and molecular level during dietary restriction.

Lorenzo Giordani
lgiordani@burnham.org
Program: Molecular Medicine
Advisor: Dr. Lorenzo Puri
Year entered program: 2009
Research Focus
Epigenetic changes, such as histone modification, chromatin remodeling and DNA methylation regulate gene expression and cell identity during development and post-natal life. Lorenzo is interested in mechanism by which epigenetic events are integrated at the chromatin level to determine the sub-sets of genes that are expressed upon the commitment of embryonic or adult stem cells toward specific cell lineages. Moreover, Lorenzo investigates how epigenetic drugs (e.g. histone deacetylase inhibitors) can selectively modulate gene expression in stem cells, by targeting genes marked by discrete epigenetic signatures.

Corinne Lee
fiametta@ucsd.edu
Program: Molecular Medicine
Advisor: Dr. Nigel Calcutt
Year entered program: 2007
Research Focus
Corinne Lee's broad research interest is in the neurological complications of diabetes mellitus. One of the primary goals of her current work is to determine causes of painful diabetic neuropathy and to identify potential therapeutics that may alleviate quality-of-life altering symptoms experienced by many patients with diabetes. Corinne is interested in the possibility that pain symptoms from peripheral neuropathies are not caused by the peripheral nervous system at all, but instead may be the result of complications of the central nervous system.
Education

Philip McQuary
pmcquary@burnham.org
Program: Molecular Medicine
Advisors: Dr. Dieter Wolf and Dr. Malene Hansen
Year entered program: 2008
Research Focus
Philip McQuary is exploring the role of the translation initiation factor eIF4E2 in protein synthesis under stressful environmental conditions. In response to stressful environmental conditions, eukaryotic cells shut down their global protein production as part of an integrated stress response. Philip is working to discover the upstream regulators that activate eIF4E2 and its downstream translational targets needed for survival under stress conditions. He uses a combination of biochemical and global approaches using fission yeast S. pombe and C. elegans as two different model organisms through the: (1) characterization of eIF4E protein interactions during oxidative stress, (2) validation of mRNAs encoding stress response proteins as candidate translational targets of eIF4E2, and (3) global assessment of eIF4E2’s role in stress-regulated translation by polysome profiling.

Judith Scheliga
Program: Molecular Medicine
Advisor: Dr. Dieter Wolf
Year entered program: 2009
Research Focus
Judith Scheliga focuses on elucidating the biochemical pathways controlled by eIF3e and on linking its loss during breast carcinogenesis to its potential role in stress-specific translation and apoptosis. The putative tumor suppressor Int6/eIF3e, a conserved subunit of the translation initiation factor eIF3, was first identified as an integration site for the mouse mammary tumor virus (MMTV), whereupon a truncated, oncogenic version of the protein is expressed (designated Int6sh), leading to mammary tumor formation. Several studies have implicated the protein in breast tumorigenesis, while the underlying mechanism remains unknown.
