Marta Markiewicz-Potoczny studies molecular pathways: the stepping stones our cells use to send signals and substances throughout our bodies.

Markiewicz-Potoczny, an assistant professor of biochemistry and molecular genetics in our University of Illinois College of Medicine, recently identified a molecular pathway that’s critical for keeping DNA healthy, and the discovery has implications for healthy aging and preventing diseases, like cancer.

Because of the pathway’s critical role in preserving telomeres, it might be used to reverse age-related telomere degradation and boost cell health throughout the lifespan. In cells that are already cancerous, sabotaging the NMD pathway could help prevent the disease from spreading.

“I’m excited to investigate NMD further to evaluate its value to both cancer prevention and healthy aging,” Marta said. “I am so lucky to do this work.”

Late last summer, nearly 300 air-quality monitoring sensors were installed on light poles throughout the city. The partnership between UI Health and Chicago Department of Public Health, called Open Air Chicago, will track local air pollution over the next five years, making it the largest system of its kind in the U.S. and the second-largest in the world.

“By pairing air-quality data with Chicagoans’ lived experiences, we can reduce exposure to pollutants and their associated health risks, improving community and public health,” said UIC School of Public Health professor and project leader Serap Erdal.

Crews installed the solar-powered sensors across Chicago’s approximately 60 ZIP codes, each less than a mile from the next. 60% of the sensors were purchased with UI Health research grants.

Industrial neighborhoods with higher pollution levels received more sensors, and in each neighborhood, residents and environmental organizations gave input as to where the sensors would go.

“Community members know where cars and trucks tend to idle, and where high-risk groups like children and older adults tend to congregate,” Erdal said. “We placed many of the sensors near daycares, schools and hospitals. The goal wasn’t just to collect data, but to educate and empower citizens to take action.”
