Within months of Alexe Webb's birth, her parents noticed eye problems. Alexe seemed unable to fix her vision on faces. Bright lights triggered prolonged bouts of staring. In dim light, she groped with her hands to find toys or snacks in plain view.

Nobody enjoys colonoscopies, including mice. University of Missouri researchers are excited about the potential of using genetic biomarkers to predict colon cancer caused by inflammation. A new method developed at the MU Research Animal Diagnostic Laboratory (RADIL) could eventually lead to a method that might eliminate colonoscopies altogether.

Researchers at the Johns Hopkins University School of Medicine have discovered that nitroxoline, an antibiotic commonly used around the world to treat urinary tract infections, can slow or stop the growth of human breast and bladder cancer cells by blocking the formation of new blood vessels. The results, appearing in the Dec. 15 issue of the Journal of the National Cancer Institute, suggest that nitroxoline shows promise as a potential therapeutic agent.

In new research from Saint Louis University, investigators have found evidence that a toxin produced by the brain is responsible for the series of cellular events that lead to Parkinson's disease. The study, published in PLoS One, found that the brain toxin DOPAL plays a key role in killing the dopamine neurons which trigger the illness.

Although most people in developed countries get plenty of calories daily, their diets are often lacking in key nutrients that their bodies have evolved to expect. Omega-3 polyunsaturated fatty acids, such as those found in fish and walnuts, are one category of crucial ingredients that the body cannot make on its own.

A professor of veterinary medicine at the University of Missouri and his team have successfully performed a knee replacement procedure in dogs using biological cartilage. The cartilage was developed from the patient's own cells, which were grown in the lab and formed for insertion into the knee.

Wed, Jan 19, 2011 — In a study published in the Cell Press journal Developmental Cell, a team of researchers led by Channing Der, PhD, Distinguished Professor of Pharmacology at UNC-Chapel Hill, took a step back to a simpler organism – a common roundworm – and made a discovery about how the Ras oncogene chooses a signaling pathway and how the consequences of that choice play out in cellular development – a key issue in cancer, which is characterized by uncontrolled cell growth.

Massachusetts General Hospital (MGH) Cancer Center researchers have discovered a previously unknown feature of common tumor cells – massive overexpression of certain DNA sequences that do not code for proteins. These DNA sequences – called satellite repeats – have been studied for their role in chromosomal structure but previously were not suspected of having a role in cancer. The report will appear in the journal Science and is receiving early online release.
