iGem students’ award-winning device instantly detects sepsis via sweat

December 2, 2021

“This year’s iGEM team tackled a problem that has a huge impact on society,” says Anne S. Meyer, an associate professor of biology, and one of the advisors for Rochester’s iGEM team. “The students realized that a patient’s sweat contains specific biomarkers that can report on whether or not the patient has sepsis. So, monitoring the levels of these biomarkers in patient sweat would be an easy and noninvasive way to diagnose sepsis in real time to get instant information.”

Vera Gorbunova discusses the strange life of naked mole rats

May 25, 2021

There’s no single force that drives cellular aging; it’s a network of feedback loops. Enzymes read genes like a grocery list of different proteins to prepare, and those proteins might protect that enzyme, or that gene, or some body-wide process. Your body is programmed to tolerate these bumps and bruises. “While we are young, that repair actually works almost flawlessly,” says Vera Gorbunova, a biogerontologist who studies mole rats at the University of Rochester. When aging sets in, though, “now damage outpaces repair.” Gene-reading enzymes falter, misfolded proteins gum up the brain, sputtering mitochondria weaken muscles, and cancers bloom.

iGEM team develops noninvasive endometriosis test

November 19, 2020

When Meghan Martin ’21, a biochemistry and American Sign Language double major, was a sophomore in high school, she began experiencing intense, chronic pain. An avid runner and soccer player, she was crippled by cramps, nausea, and back spasms that left her unable to participate in the sports she loved.

“I’ve always been really active, but I would go to practice, and then I would come home and have to lay down because my back would be spasming so badly,” Martin says. “I would start throwing up because I was so nauseous and in so much pain.”

Initially when she sought help, her doctor told her it was just period cramps and that she should take aspirin and get additional rest. Her mother, however, sensed there was something more going on. After some online research, she found that her daughter was exhibiting symptoms characteristic of endometriosis, a chronic disease in which tissue similar to the tissue that normally lines the inside of the uterus grows outside the uterine cavity.


Anne Meyer's research may lead to more effective antibiotics, less antibiotic resistance

October 1, 2020

Doctors often treat ear infections, strep throat, and urinary tract infections with antibiotics that kill the bacteria causing these infections. Sometimes, however, bacteria mount strong responses to stressors such as antibiotics, allowing these “stressed” bacteria to survive. This is especially the case when a person takes multiple antibiotics.

Gorbunova and Seluanov Think Bats May Offer Clues to Treating COVID-19

July 13, 2020

“We’ve been interested in longevity and disease resistance in bats for a while, but we didn’t have the time to sit and think about it,” says Gorbunova, the Doris Johns Cherry Professor of Biology at Rochester. “Being in quarantine gave us time to discuss this, and we realized there may be a very strong connection between bats’ resistance to infectious diseases and their longevity. We also realized that bats can provide clues to human therapies used to fight diseases.”

Nancy Chen Seeks to Understand an Endangered Species, Bird by Bird

September 27, 2019

According to a recent analysis published in the journal Science, the number of birds in the United States and Canada has declined by nearly 3 billion—a shocking 29 percent of the total—since 1970. The study paints a bleak picture of avian loss among not only endangered species, but supposedly abundant birds like sparrows, and raises questions fundamental to evolutionary biology: What are the genes that influence survival and reproduction? What happens to the genetics of a population when it becomes threatened by extinction? Why do some individuals fare better than others? How do natural populations evolve over short time-scales?


Jack Werren Says Genetics Models Move Beyond Drosophila and the Humble Lab Mouse

September 10, 2019

Geneticists tend to crowd around a few favorite organisms that have long histories in research and a wealth of practiced protocols for manipulating their genes. But those organisms aren’t always the best choice to answer a scientific question, leading some researchers to use other, less popular models. Organisms from elsewhere across the tree of life might offer unique genetic structures, physiology closer to that of humans, or faster generation times to accelerate investigations into gene regulation, evolution, and development.


Anne Meyer says CRISPR Now Cuts and Splices Whole Chromosomes

September 3, 2019

Imagine a word processor that allowed you to change letters or words but balked when you tried to cut or rearrange whole paragraphs. Biologists have faced such constraints for decades. They could add or disable genes in a cell or even—with the genome-editing technology CRISPR—make precise changes within genes. Those capabilities have led to recombinant DNA technology, genetically modified organisms, and gene therapies. But a long-sought goal remained out of reach: manipulating much larger chunks of chromosomes in Escherichia coli, the workhorse bacterium. Now, researchers report they've adapted CRISPR and combined it with other tools to cut and splice large genome fragments with ease.

Amanda Larracuente Sequences the Genome’s Elusive Centromere

May 15, 2019

Researchers from the University of Rochester, along with their colleagues at the University of Connecticut, have now discovered the centromeres of the model genetic organism Drosophila melanogaster (fruit fly), sequencing the most repetitive parts of genome and unlocking one of the “last frontiers of genome assembly,” says Amanda Larracuente, an assistant professor of biology at Rochester and co-lead author on the study. The research, published in the journal PloS Biology, sheds light on a fundamental aspect of biology, and shows that selfish genetic elements may play a larger role in centromere function than researchers previously thought.

Amanda Larracuente Recipient of National Science Foundation’s Prestigious Faculty Early Career Development (CAREER) Award

April 11, 2019

Amanda Larracuente, an assistant professor of biology, will investigate the function and evolution of centromeres in fruit flies. Centromeres, which vary in size and complexity across organisms, are regions of the chromosome that are essential in ensuring chromosomes separate properly during cell division. Variations in centromeres can have an impact on genome evolution, speciation, and human disease. Larracuente will study the variation of centromeres within and between species to gain insights into their DNA sequences. She will also examine how a class of selfish genetic elements called retrotransposons shape aspects of centromeres. (Read more here.)

Gorbunova and Seluanov Labs Say ‘Selfish’ Genetics Amplify Inflammation, Age-related Diseases

March 15, 2019

Aging affects every living organism, but the molecular processes that contribute to aging remain a subject of debate. While many things contribute to the aging process, one common theme in animal aging is inflammation—and this may be amplified by a class of selfish genetic elements.

The human genome is littered with selfish genetic elements—repetitive elements that do not seem to benefit their hosts, but instead seek only to propagate themselves by inserting new copies into their host genomes. A class of selfish genetic elements called LINE1 retrotransposons are the most prevalent retrotransposon selfish genetic elements found in humans; approximately 20 percent of both human and mice genomes are composed of LINE1s.

Amanda Larracuente Says the Male Y Chromosome is Not a Genetic Wasteland

February 7, 2019

Y chromosomes are sex chromosomes in males that are transmitted from father to son; they can be important for male fertility and sex determination in many species. Even though fruit fly and mammalian Y chromosomes have different evolutionary origins, they have parallel genome structures, says Larracuente, who co-authored the paper with her PhD student Ching-Ho Chang. “Drosophila melanogaster is a premier model organism for genetics and genomics, and has perhaps the best genome assembly of any animal. Despite these resources, we know very little about the organization of the Drosophila Y chromosome because most of it is missing from the genome assembly.”


Daven Presgraves Explains What Makes A Species Different

January 7, 2019

Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won’t or can’t mate with one another, or, if they do, the resulting offspring are often sterile, unviable, or suffer some other sort of reduced fitness.
