UH biochemist works to revolutionize ovarian cancer treatment
Date:12/21/2010

HOUSTON, Dec. 21, 2010 The day when an ovarian cancer patient can treat her tumor with a single, painless pill instead of a toxic drug cocktail is the ultimate goal of the pioneering research of a University of Houston (UH) scientist.

Preethi Gunaratne, assistant professor in the department of biology and biochemistry, is studying a class of tiny genetic molecules known as microRNAs and pinpointing those that could unleash the body's natural cancer-fighting agents. Additionally, she is developing a novel method to effectively deliver this treatment to the targeted cells by using an unusual carrier nanoparticles of gold through the work of Lalithya Jayarathne, a postdoctoral researcher in Gunaratne's lab.

Gunaratne's potentially groundbreaking work in ovarian cancer has gained exceptional notice and momentum this year with a series of high-profile research grants. In October, her ovarian cancer project was awarded a $200,000 High Impact/High Risk grant from the Cancer Prevention and Research Institute of Texas (CPRIT), which oversees the state's billion-dollar war on cancer. In November, she was approved for a $250,000 grant from Houston's Cullen Foundation. Earlier this year, she was chosen a beneficiary of the Baylor College of Medicine Partnership Fund.

Each year, the Baylor partnership undertakes a major fundraising campaign for a specific health project. For 2010-11, the partnership is raising money to fund the collaborative ovarian cancer project of Gunaratne and Baylor researchers Matthew Anderson and Martin Matzuk.

All this promising research has its origins in a revolution in genetic science that began just a few years ago. Attention has long centered on nucleic acids known as DNA, with little consideration given to its cousin RNA or to microRNAs, which were considered "genetic junk" that played no significant role in the human genome, Gunaratne said.

That began to change earlier this decade as sc
