Bérénice Benayoun studies possibility of rejuvenating genes

Bérénice Benayoun, assistant professor at the USC Leonard Davis School of Gerontology and principal investigator with USC Stem Cell, explores the role of epigenetics—the ways that genes turn “off” or “on”—in the process of aging, and she hopes her findings could eventually help delay frailty and prolong healthy life.

Pinchas Cohen recognized as top influencer in aging field

A newly published list of 2017’s top 50 “Influencers in Aging” includes Pinchas Cohen, dean of the USC Leonard Davis School of Gerontology and principal investigator with USC Stem Cell. The list appeared on the baby boomer-focused online news platform Next Avenue.

Drugs widely used in cancer therapy increase toxicity of chemotherapy in mice

A short-term fast appears to counteract increases in blood sugar caused by common cancer drugs and protect healthy cells in mice from becoming too vulnerable to chemotherapy, according to new research by Valter Longo, professor at the USC Leonard Davis School of Gerontology professor, director of the USC Longevity Institute and principal investigator with USC …

Fasting-mimicking diet may reverse diabetes in mice

By Beth Newcomb A diet designed to imitate the effects of fasting appears to reverse diabetes, a new USC-led study shows. The fasting-like diet promotes the growth of new insulin-producing pancreatic cells that reduce symptoms of type 1 and type 2 diabetes in mice, according to the study on mice and human cells led by …

Proper stem cell function requires hydrogen sulfide

Stem cells in bone marrow need to produce hydrogen sulfide in order to properly multiply and form bone tissue, according to a new study in Cell Stem Cell from the Center for Craniofacial Molecular Biology at the Ostrow School of Dentistry of USC. Professor Songtao Shi, principal investigator on the project, said the presence of …

Dental study provides wealth of stem cell details

An Ostrow School of Dentistry of USC study has uncovered new details on how bundles of nerves and arteries interact with stem cells and also showcases revolutionary techniques for following the cells as they function in living animals. Principal investigator Yang Chai, director of the Center for Craniofacial Molecular Biology at the Ostrow School and …

Healthy stem cells can create benign tumors in jaw

A new study from the Ostrow School of Dentistry of USC published in Cell Stem Cell illustrates how changes in cell signaling can cause ordinary stem cells in the jaw to start forming benign but potentially harmful tumors. Principal investigator Songtao Shi, professor at the Ostrow School’s Center for Craniofacial Molecular Biology, said ossifying fibromas, …

Ostrow School study links growth factor glitch to tongue defects

New findings about how cell signaling directs tongue development may have big clinical applications for healing tongue defects, according to an Ostrow School of Dentistry of USC study published in The Journal of Biological Chemistry. According to Professor Yang Chai, the study’s principal investigator and director of the Center for Craniofacial Molecular Biology at the …

Stem cells found in gum tissue can fight inflammatory disease

Stem cells found in mouth tissue can not only become other types of cells but can also relieve inflammatory disease, according to a new Ostrow School of Dentistry of USC study in the Journal of Dental Research.

Ostrow School investigators recognized for research

The International Association of Dental Research (IADR) honored two scientists from the Ostrow School of Dentistry of USC at the association’s general session opening ceremonies on March 20 in Seattle. Professor Songtao Shi and Postdoctoral Research Associate Carolina Parada, two researchers in the Ostrow School’s Center for Craniofacial Molecular Biology (CCMB), were the honorees.
