But they are intriguing to researchers for a variety of reasons: they have the longest life span of rodents (an average of 30 years), they are resistant to a variety of age-related diseases such as cancer, and they tend to remain fit and active until very advanced ages. The Gorbunova Lab at the University of Rochester studies these rodents in the hopes of unraveling their unique anti-cancer properties. (University of Rochester photo / J. Adam Fenster)
Another piece to the puzzle in naked mole rats’ long livesNaked mole rats—with their long life span of up to 30 years and remarkable resistance to age-related diseases—offer scientists key clues to the mysteries of aging and cancer.
That’s why biology professors Vera Gorbunova and Andrei Seluanov and postdoctoral associate Yang Zhao studied naked mole rats to see if the rodents exhibit an anticancer mechanism called cellular senescence—and, if so, “how the mechanism might work differently than in short-lived animals, like mice,” says Zhao, the lead author of the study, which as been published in PNAS.
Cellular senescence is an evolutionary adaptation that prevents damaged cells from dividing out of control and developing into full-blown cancer. However, senescence has a negative side too: by stopping cell division in order to prevent potential tumors, it also accelerates aging.
Previous studies indicated that when cells that had undergone senescence were removed from mice, the mice were less frail in advanced age as compared to mice that aged naturally with senescent cells intact.
Researchers therefore believed senescence held the key to the proverbial fountain of youth; removing senescent cells rejuvenated mice, so perhaps it could work with human beings. Companies began investigating drugs—known as senolytic agents—that would kill senescent cells and translate the anti-aging effects to humans.
But is eliminating senescence actually the key to preventing or reversing age-related diseases, namely cancer?
“In humans, as in mice, aging and cancer have competing interests,” Gorbunova says. “In order to prevent cancer, you need to stop cells from dividing. However, to prevent aging, you want to keep cells dividing in order to replenish tissues.”
In their recent study, Zhao, Seluanov, Gorbunova, and their collaborators compared the senescence response of naked mole rats to that of mice, which live a tenth as long—only about two to three years. “We wanted to look at these animals that pretty much don’t age and see if they also had senescent cells or if they evolved to get rid of cell senescence,” Seluanov says.
Their unexpected discovery? Naked mole rats do experience cellular senescence, yet they continue to live long, healthy lives; eliminating the senescence mechanism is not the key to their long life span. However, the researchers found that although naked mole rats exhibited cellular senescence similar to mice, their senescent cells also displayed unique features that may contribute to their cancer resistance and longevity.
The cellular senescence mechanism permanently arrests a cell to prevent it from dividing, but the cell still continues to metabolize. The researchers found that naked mole rats are able to more strongly inhibit the metabolic process of the senescent cells, resulting in higher resistance to the damaging effects of senescence.

Plagiarism detection software now available to faculty, researchersThe University is making plagiarism detection software available to its faculty and researchers to use on a voluntary basis.
iThenticate, used by federal funding agencies and major publishers, allows researchers to easily upload and scan documents, manuscripts, research, and other professional works, which are then compared against more than 72 billion active and historical archived web sites, 165 million offline publication articles, and several major library networks.
“It is very robust,” says Gunta Liders, the associate vice president for research administration.
The decision was made after a review of University policies in light of “some pretty high-profile instances of research misconduct” at other prestigious schools the last couple of years, she says.
“Our policies are solid, and we’ve got great responsible-conduct-of-research classes for undergraduates, graduate students, and postdocs,” she says. However, iThenticate offers an added layer of protection against deliberate or inadvertent instances of plagiarism, which can result in time-consuming investigations, possible loss of federal funding, and “reputational harm to both the individual and institution,” she says.
iThenticate is also used by:
- The federal agencies that fund most of the University’s research, including the Department of Energy, the National Institutes of Health, and the National Science Foundation.
- Most of the University’s peer institutions. “They are very happy in terms of how it works and ease of use,” Liders says.
- All of the major publishers of research journals.
“We are really encouraging our faculty to use this for grant applications, and for papers submitted to journals,” Liders says.
For now, the software will be available only to faculty members and researchers. Postdocs and graduate students who wish to use iThenticate should do so through their faculty advisor.

Changing the game for melanoma treatmentWilmot Cancer Institute patients with advanced melanoma (stage III) now have more options for treatment, thanks to research co-authored by a Medical Center surgical oncologist and published in Lancet Oncology.
The study involved comparing two treatment approaches for high-risk melanoma patients with a BRAF gene mutation in their cancer: standard care, which calls for upfront surgery, or giving a two-drug, targeted therapy regimen before surgery and again afterward. Patients in the latter group had longer disease-free survival in the Phase 2 trial, and after seven months researchers halted the study earlier than expected due to the positive results.
“What’s so exciting is that neo-adjuvant therapy (giving a cancer drug before surgery) had never been done before in melanoma,” said Peter Prieto, assistant professor of surgery and oncology, who helped to lead the study when he was completing a fellowship at MD Anderson Cancer Center. He joined the faculty in Rochester last year.
“And in this trial we not only saw that patients receiving the neoadjuvant therapy were doing much better, but 58 percent of them had a complete pathologic response. That means that when their tumor was removed it had no viable cancer cells in it,” Prieto said.

Study helps assess community engagementResearchers at the Clinical and Translational Science Institute (CTSI) have created a two phase assessment process to help academic health centers map, track, and bolster their community engagement efforts. Teams at several institutions piloted the process and reported that it was easy to adapt to their individual needs and helped them identify gaps in their resources for community engagement.
As health care shifts from traditional disease treatment models to broader population health approaches, is imperative that research teams engage with communities to understand their needs and develop projects that will address issues affecting their well-being. While community engagement is increasingly important, academic health centers struggle to demonstrate the effectiveness of their community-engaged activities.
The CTSI pilot study was led by Karen Vitale, network coordinator in the Center for Community Health and Prevention, and Gail Newton, former director of Community Health Partnerships at the Medical Center. The pair recruited seven other academic health centers to assemble community engagement-savvy teams and test out the tool, which includes two self-assessment surveys.
The Institutional Community Engagement (ICE) Self-Assessment, which was developed at Rochester, helps institutions map their community engagement activities by structure, process, and outcome measures. This assessment helps put each institution’s community engagement activities into context and creates a baseline for tracking their progress over time.
The Community-Campus Partnerships for Health (CCPH) Self-Assessment identifies existing resources for community engagement. Institutions evaluate the level of commitment to community engagement of their leadership, faculty, students, and community. It also assesses the institution’s capacity for community engagement scholarship and identifies opportunities for action.
