Grad Student Research Sparks Innovation through AAPS Awards

At this week’s AAPS 2012 Annual Meeting in Chicago, graduate students across the country are being honored for their research and work in bio/pharmaceutical innovation. BioPharm International had the chance to talk with a few of the recipients.

Biotechnology winner David W. Woessner noted that his team’s work at the University of Utah on Synthetically Lethal Combinations for CML Therapy demonstrates the first development of a protein/peptide-based therapeutic for CML. “While current therapies in the clinic (tyrsosine kinase inhibitors) act on the ABL portion of the protein, we are demonstrating efficacy by targeting the BCR portion, necessary for oligomerization and activation of the tyrosine kinase. Additionally this work also exploits a combination therapy approach early in development,” he said.

Lakshmi Prasanna Kolluru who won for drug design and development focused her work on albumin-based theragnostic nanoparticles for tumor targeted drug delivery. Based Mercer University, the PhD candidate says she was inspired as a teenager by her cousin, a cancer patient suffering from the side effects of chemotherapy. “She was disturbed psychologically when she had lost her hair due to side effects and this spurred the interest in me to focus on cancer research. So, when my professor gave me the freedom to design a project, I opted to work on development of a delivery system that targets anti cancer drugs to tumor and reduces the side-effects of chemotherapy,” said Kolluru.

University of California San Francisco student Rachel Jean Eclov won for her research into In Vivo Characterization of ABCG2 Enhancers, in the category of Pharmacokinetics, Pharmacodynamics, Drug Metabolism and Clinical Pharmacology and Translational Research. “Previous research on MXR functionality has been mostly aimed at functional (coding) variants of MXR. My research is unique in that it looks for how other types of genomic variations can alter MXR expression and thus drug disposition. I utilize epigenetic tools to unravel how MXR expression can be tissue specific or transiently increased or decreased,” she explains. “I then consider how genetic variation in identified regulatory elements can alter the transcriptional properties of that element. Although other epigenetic research has been published, the majority of it is on variations in regulatory elements that cause developmental defects. My research uses epigenetics to identify genetic variations that impact the more subtle world of drug disposition where the effects of these variations are not as obvious but can be just as severe.”
