Genes Evolve to Minimize Protein Production Errors

AUSTIN, Texas--Genetic evolution is strongly shaped by genes’ efforts to prevent or tolerate errors in the production of proteins, scientists at The University of Texas at Austin and Harvard University have found. Their study also suggests that the cost of errors in protein production may lie in the malformed proteins themselves, rather than in th...

Chemists Receive NIH Grant for Cancer Research

AUSTIN, Texas--Chemistry researchers at two Central Texas universities have received a four-year, $1,113,615 grant from the National Institutes of Health to evaluate a new technique that could rapidly predict the anti-cancer activity of new compounds. Lynn Guziec, assistant professor of chemistry at Southwestern University, will collaborate on the...

Saliva Can Help Diagnose Heart Attack

AUSTIN, Texas—Early diagnosis of a heart attack may now be possible using only a few drops of saliva and a new nano-bio-chip, a multi-institutional team led by researchers at The University of Texas at Austin reported at a recent meeting of the American Association for Dental Research. The nano-bio-chip assay could some day be used to analyze a pa...

Calorie Restricted Diet Prevents Pancreatic Inflammation and Cancer

Prevention of weight gain with a restricted calorie diet sharply reduced the development of pancreatic lesions that lead to cancer in preclinical research reported today by researchers from The University of Texas at Austin and The University of Texas M. D. Anderson Cancer Center at the American Association for Cancer Research annual meeting. The ...
Gene Discovery Made Easier

Gene Discovery Made Easier

AUSTIN, Texas—The identification of disease-causing genes will be much easier and faster using a powerful new gene-networking model developed by researchers at The University of Texas at Austin. Edward Marcotte and his colleague, postdoctoral researcher Insuk Lee, used the gene network technique to identify new genes that regulate life span and ar...

Detecting Cancer With Saliva

HOUSTON, Texas—Biochemist John McDevitt’s lab-on-a-chip technology was used by researchers at The University of Texas Health Science Center at Houston to identify and quantify specific protein markers in human saliva to provide an early, non-invasive diagnosis of breast cancer. The hope is that people may some day receive cancer screening simply a...

Tolerance to Inhalants May Be Caused By Changes in Gene Expression

Changes in the expression of genes may be the reason why people who abuse inhalants, such as spray paint or glue, quickly develop a tolerance, biologists at The University of Texas at Austin have discovered.

Higher Brain Damage in Alcoholics with Cirrhosis of the Liver

AUSTIN, Texas—An examination of gene expression in the frontal cortex has found that brain function is even more impaired in alcoholics with cirrhosis of the liver, one of the most common and serious medical complications linked to alcoholism. Sustained exposure to alcohol can cause scarring and dysfunction of the liver, referred to as cirrhosis. ...
