Pharmacogenetics News and Research

RSS

The terms pharmacogenomics and pharmacogenetics are often used interchangeably to describe a field of research focused on how genes affect individual responses to medicines. Whether a medicine works well for you—or whether it causes serious side effects—depends, to a certain extent, on your genes.

Just as genes contribute to whether you will be tall or short, black-haired or blond, your genes also determine how you will respond to medicines. Genes are like recipes—they carry instructions for making protein molecules. As medicines travel through your body, they interact with thousands of proteins. Small differences in the composition or quantities of these molecules can affect how medicines do their jobs.

These differences can be due to diet, level of activity, or the medicines a person takes, but they can also be due to differences in genes. By understanding the genetic basis of drug responses, scientists hope to enable doctors to prescribe the drugs and doses best suited for each individual.

IPIT uses Affymetrix’s DMET Plus biomarker panel to expand the PGENI

Affymetrix, Inc. announced today that the Institute for Pharmacogenomics and Individualized Therapy (IPIT) at the University of North Carolina in Chapel Hill is using the company’s DMET™ Plus biomarker panel to expand the Pharmacogenetics for Every Nation Initiative (PGENI).

Clinical trial helps improve prognosis and changes the standard of care for patients with colorectal cancer

In a review article published this month in The Oncologist, UNC's Dr. Richard M. Goldberg and a team of colleagues catalogue how the data collected in a single large comparative clinical trial testing combination chemotherapy for metastatic colorectal cancer has been used not only to benefit the patients that enrolled but also patients who subsequently developed the disease.

Participants in antidepressant drug trials are atypical patients

One reason antidepressant medication treatments do not work as well in real life as they do in clinical studies could be the limited type of study participants selected, researchers at UT Southwestern Medical Center have found.

Optimizing dosage of blood-thinning drug warfarin

In a large-scale study and an upcoming clinical trial, scientists supported by the National Institutes of Health address one of the trickiest issues in prescribing medicine - how to quickly optimize each patient's dosage of the common blood-thinning drug warfarin.

Ondansetron shown to be a viable treatment option for opioid addiction

Scientists at Stanford University School of Medicine have discovered that a commonly available non-addictive drug can prevent symptoms of withdrawal from opioids with little likelihood of serious side effects.

Genetic biomarker linked to subcutaneous growth hormone dose-response

The interindividual variability of response to subcutaneously applied protein-based drugs remains poorly understood. However, defining genetic markers that can be associated with biological effects of such drugs may improve the understanding of individual variability of response and even drug resistance.

Variations in the serotonin transporter gene may determine who responds best to antidepressant

A new Mayo Clinic study shows that variations in the serotonin transporter gene could explain why some people with depression respond better than others to treatment with citalopram (Celexa), an antidepressant medication.

Marketing of unproven genetic tests a threat to public health

No mechanism currently exists to ensure that genetic tests are supported by adequate evidence before they go to market, or that marketing claims are truthful and not misleading, according to a policy analysis to be published April 4 in Science.

FDA Critical Path Initiative addresses differences between women's and men's health outcomes

Advanced medical technology and analysis methods now being promoted through the Food and Drug Administration's Critical Path Initiative to facilitate the development of drugs, biologics and devices can help address differences between women and men in the detection and treatment of disease, according to a paper published in the Winter 2007 issue of Drug Discovery Today: Technologies.

Lithium commonly used to treat bi-polar disorder increases lifespan in Nematode worms

Nematode worms treated with lithium show a 46 percent increase in lifespan, raising the tantalizing question of whether humans taking the mood affecting drug are also taking an anti-aging medication.
