Dr Gorbunova’s laboratory studies why certain animals, such as the extremely long-lived, hairless, and so-ugly-they’re-cute subterranean dwellers known as naked mole-rats, are extraordinarily resistant to cancer. The unusual rodents from eastern Africa have a eusocial colony structure reminiscent of honeybees and can live more than 40 years in captivity, roughly 10-fold longer than mice.&lt;/p&gt;&lt;p&gt;As part of its research, Dr Gorbunova’s laboratory grew naked mole-rat fibroblast cells, which make and secrete collagen and other components of the framework for connective tissues. Graduate students noticed that the cells also were secreting a viscous substance into the cell culture dish. The substance was so thick and gooey that it clogged the vacuum pump used to suck up the growing medium from the dishes. “When people complained about it, we all thought, ‘Well, there must be something interesting,’” Dr Gorbunova recalls.&lt;/p&gt;&lt;p&gt;After initial tests suggested that the viscous substance was not an overabundant protein, a Google search hinted at hyaluronic acid, a natural lubricant and cushion for skin and other sensitive body parts in humans and other animals. Sure enough, confirmatory tests revealed that the secretions were a very long form of hyaluronic acid made by the &lt;i&gt;HAS2&lt;/i&gt; gene.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;From additional experiments, the laboratory found that this version of hyaluronic acid binds to a specific cell receptor and appears to trigger an anticancer response by arresting cell growth and division. “Basically, when there is a lot of high-molecular weight hyaluronic acid in the tissue, it reduces cell proliferation and it also slows down premalignant hyperplastic cells,” Dr Gorbunova says. In transgenic mice, the introduced &lt;i&gt;HAS2&lt;/i&gt; gene granted the animals more longevity and resistance to both spontaneous and induced tumors.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; “They didn’t become completely resistant like naked mole-rats, which means there are additional mechanisms that are different in the mole-rat, but the incidence was reduced significantly,” she says.&lt;/p&gt;&lt;p&gt;From an evolutionary perspective, Dr Gorbunova doubts that anticancer activity was the original purpose of the naked mole-rats’ hyaluronic acid production. In a wide range of other tunnel-dwelling species, the researchers recently reported that all produced the same high-molecular-weight compound.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt; “What we proposed is that it really becomes upregulated with adaptation to subterranean life,” she says. One possibility is that because underground animals are constantly rubbing against tunnel walls, the acid helps to reinforce their skin.&lt;/p&gt;&lt;p&gt;When the laboratory ramped up hyaluronic acid production in mice, the animals likewise acquired “very stretchy, elastic skin,” she says. “But then once it’s ov","PeriodicalId":9410,"journal":{"name":"Cancer Cytopathology","volume":"132 8","pages":"463-464"},"PeriodicalIF":2.6,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cncy.22887","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141874177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Another 1300 individuals are diagnosed with adenoid cystic carcinomas (ACCs), which arise primarily in the salivary glands, commonly invade nerves, and metastasize to distant sites such as the lungs in approximately half of all cases.&lt;/p&gt;&lt;p&gt;Both cancers are rare enough that patients often struggled to connect with others facing the same malignancy until social media platforms such as Facebook helped them to connect through patient support groups. Such groups, in turn, have become critical resources for research efforts seeking to better understand the diseases and improve patient outcomes.&lt;/p&gt;&lt;p&gt;Amid the spate of recent warnings about the dangers of social media, including rampant misinformation, online groups have become the main vehicle for connecting patients and families affected by rare diseases. Physicians now regularly recommend Facebook groups to their patients, says Meghan Halley, PhD, MPH, a senior research scholar at the Stanford Center for Biomedical Ethics in Palo Alto, California. “It’s often the largest gathering of any patients with a particular very rare disease that’s available,” she says. “The extent to which the rare disease community has leveraged social media to identify other patients, share information, and provide social support is one of the few bastions of really good news in the social media space.”&lt;/p&gt;&lt;p&gt;Researchers have made good use of the space as well. In collaboration with the Granulosa Cell Tumor Survivor Sisters Facebook group, for example, a recent study based on an online survey of 743 patients revealed that 30% of respondents had recurrent disease, with one third of those recurrences occurring within 5 years of diagnosis.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; The study represented one of the largest surveys yet of GCT patients’ treatment experiences. “Using naturally forming consumer groups may assist with developing the evidence base for care and supporting those living with GCT ovarian cancer,” the authors concluded.&lt;/p&gt;&lt;p&gt;Bioethicists such as Dr Halley, however, also have urged caution when relying on social media for bolstering research efforts. In a review of 120 social media–aided studies on rare noncancer diseases, she and her colleagues found that more than half relied exclusively on surveys, and the patient demographics, when reported, skewed toward female and White participants. “Despite its potential benefits in rare disease research, the use of social media is still methodologically limited, and the participants reached may not be representative of the rare disease population by gender, race, age, or rare disease type,” wrote the researchers.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;Rare cancers are tracked, in part, through the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program.
