I have a background on transcriptional regulation in the context of toxicology, reproductive and adipose tissue biology. My current interests lie in deriving stem cell lines,
investigating molecular mechanisms of stem cell maintenance and derivation and using ES and iPS cells to model neurodegenerative disease states such as ALS

My focus is on signal transduction pathways that are of particular importance to stem cells. The purpose of this focus is to identify mechanisms that activate endogenous
stem cells (for the purpose of regenerative interventions) and provide targets for novel anti-cancer approaches

Thales Papagiannakopoulos
University of California, Santa Barbara, PhD candidate
With over 600 miRNA genes identified experimentally in the human genome and a plethora of computatiaonally predicted mRNA targets, it is believed that these small
RNAs have a central role in diverse cellular and developmental processes. Therefore aberrant expression of miRNA genes could lead to human disease, including
cancer. Studies from our group and other have confirmed that miRNAs regulate cell proliferation and apoptosis. Furthermore, these non-coding RNAs can control cellular
identity and mediate differentiation.
miRNAs are playing an important role in inducing and maintaining the oncogenic state of various types of cancer. This function lies within their ability to target multiple
transcripts including many tumor suppressor genes or oncogenes.
With the use of gliomas as a model, I aim to determine the role of miRNAs in epigenetically regulating oncogenesis and tumor maintenance.

- Electrophysiology

Diomedes Logothetis
Virginia Commonwealth University, Professor and John D. Bower Chair in Physiology
Our aim is  to understand ion channel regulation of gating in molecular terms. They are particularly interested in the regulation of ion channel activity by the βγ subunits of
GTP-binding (G) proteins and by signaling phosphoinositides in the inner leaflet of the plasma membrane. Studies utilizing electrophysiology and molecular dynamic
simulations are probing channel-PIP2 interactions. Post-translational modifications or protein-protein interactions regulate channel activity in a phosphoinositide-
dependent manner and do so by targeting sites proximal to the channel-PIP2 amino acid residues. Ongoing studies are aiming to test the hypothesis that modulators of
channel activity that depend on phosphoinositides work by adjusting channel-PIP2 interactions. The physiological implications of regulation of channel activity by G
proteins and phosphoinositides is studied in model cells and also examined in cardiac and neuronal systems. Disease models of aberrant phoshoinositide regulation in
transgenic animals and neuronal cell lines are being explored.
