Drug safety, efficacy, and potential new cancer biomarker predicted by NextBio
Date:10/14/2011

SANTA CLARA, CA (October 14, 2011): New research presented this week highlights the ability of NextBio to help life scientists and clinicians investigate publicly available genomic data to assess biological mechanisms underlying drug toxicity, as well as discover prospective cancer biomarkers for further validation. The unique capabilities of NextBio to search and make discoveries, not possible by other methods, from the massive amounts of genomic data increasingly available in the public domain is the subject of two poster presentations at the American Society of Human Genetics/International Congress of Human Genetics meeting in Montreal, October 11-15.

In one presentation, the authors showed how NextBio's web-based tools and integrative genomics data could be used to evaluate potential drug toxicities and suggest treatment alternatives for women experiencing "hot flashes" (vasomotor symptoms) as a result of breast cancer chemotherapy. In another presentation, NextBio authors demonstrated how genomic data from disparate sources could be brought together and analyzed on the NextBio platform to suggest a potential new cancer biomarker in a region of the genome previously termed a "gene desert."

Drug Toxicity, Alternative Therapy Identified by NextBio

NextBio analysis offers the potential to inform clinical medicine through its ability to predict drug toxicities, as illustrated by a study of tibolone, a drug widely used to treat menopausal vasomotor symptoms. In 2009, a clinical trial tested this drug as a potential therapy for similar symptoms in women undergoing breast cancer treatment. The trial was cut short early because of the significant increase in cancer recurrence observed in those women.

The authors' investigation of public genomic data curated by NextBio found positive correlations between tibolone-induced gene expression changes and those seen in breast cancer, as well as similarities to the gene expression
