Just as the fossil record reveals clues about the conditions in which prehistoric animals and plants once lived, newly discovered genetic signatures in bacterial evolution may one day allow hospitals, doctors and scientists to know more about the environment where a bacterial infection originated.
A research team led by scientists at The University of Texas Austin has engineered an enzyme that safely treats prostate and breast cancer in animals and also lengthens the lifespan of models that develop chronic lymphocytic leukemia. The new treatment and results from preclinical trials are described in a paper published in the Nov. 21 issue of Nature Medicine.
For healthy cells to become cancerous cells, they have to lose several systems that regulate healthy function such as cell growth and division and DNA repair. New findings from University of Texas at Austin researchers about how one such regulatory system works could aid in efforts to develop personalized treatments for cancer.
A team of engineers and scientists at The University of Texas at Austin is reporting new findings on how the influenza vaccine produces antibodies that protect against disease, research that suggests that the conventional flu vaccine can be improved. The findings were reported in the journal Nature Medicine on Nov. 7.
As we head into flu season, researchers at The University of Texas at Austin are announcing the results of three flu studies: One suggests a possible new target for drugs to combat the flu; another study forecasts how effective this year's flu vaccine might be; and a third looks at ways to improve the process of identifying flu strains in the wild and thus improve how strains are selected for inclusion in each year's vaccine.
A $2 million recruitment grant from the Cancer Prevention and Research Institute of Texas (CPRIT) has paved the way for The University of Texas at Austin to welcome a scientist experienced in cutting-edge molecular biology technologies that are used to study disease and DNA repair.
Scientists studying how microbes evolve have long assumed that nearly all new genetic mutations get passed down at a predictable pace and usually without either helping or hurting the microbe in adapting to its environment. In a new study published in the journal Nature, an international team of researchers studying tens of thousands of generations of E. coli bacteria report that most new genetic mutations that were passed down were actually beneficial and occurred at much more variable rates than previously thought.
Researchers from The University of Texas at Austin and elsewhere have determined that two bacterial species commonly found in the human mouth and in abscesses, cooperate to make the pathogenic bacterium, Aggregatibacter actinomycetemcomitans, more infectious. Key to the cooperation is that the harmless partner provides the pathogen with an oxygen-rich environment that helps it flourish.
For 3 billion years, one of the major carriers of information needed for life, RNA, has had a glitch that creates errors when making copies of genetic information. Researchers at The University of Texas at Austin have developed a fix that allows RNA to accurately proofread for the first time.
Scientists at The University of Texas at Austin have developed a new method to rapidly detect a single virus in urine, as reported this week in the journal Proceedings of the National Academy of Sciences.
It took nearly a half trillion tries before researchers at The University of Texas at Austin witnessed a rare event and perhaps solved an evolutionary puzzle about how introns – noncoding sequences of DNA located within genes – multiply in a genome.
Scientists have identified genetic mutations that appear to be a key culprit behind a suite of birth defects called ciliopathies, which affect an estimated 1 in 1,000 births. In a paper published online this week in Nature Genetics, a team of researchers led by The University of Texas at Austin's John Wallingford reveals that these mutations prevent certain proteins from working together to smooth the way for cells to communicate with one another.
Researchers at the University of Texas at Austin have for the first time revealed how a group of drugs that are being developed to treat hepatitis C works. Pharmaceutical companies might be able to apply these new insights to future drugs designed to address a deadly disease.
In honor of National DNA Day, we take a look at the myriad ways that researchers in the College of Natural Sciences use deoxyribonucleic acid (DNA) and genomic information to fight disease, improve agriculture and illuminate the wonders of the natural world.
