Their key discoveries on how bats prevent cancer:<\/p>\n<ul>\n<li>Bats and humans have a gene called p53, a tumor-suppressor that can shut down cancer. (Mutations in p53, limiting its ability to act properly, occur in about half of all human cancers.) A species known as the \u201clittle brown\u201d bat\u2014found in Rochester and upstate New York\u2014contains two copies of p53 and has elevated p53 activity compared to humans. High levels of p53 in the body can kill cancer cells before they become harmful in a process known as apoptosis. If levels of p53 are too high, however, p53 eliminates too many cells. But bats have an enhanced system that balances apoptosis effectively.<\/li>\n<li>An enzyme called telomerase is inherently active in bats, which allows their cells to proliferate indefinitely. This is an advantage in aging because it supports tissue regeneration during aging and injury. If cells divide uncontrollably, though, the higher p53 activity in bats compensates and can remove cancerous cells that may arise.<\/li>\n<li>Bats have an extremely efficient immune system, knocking out multiple deadly pathogens. This also contributes to bats\u2019 anti-cancer abilities by recognizing and wiping out cancer cells, Gorbunova says. As humans age, the immune system slows, and people tend to get more inflammation (in joints and other organs), but bats are good at controlling inflammation. This intricate system allows them to stave off viruses and age-related diseases.<\/li>\n<\/ul>\n<h3>How does bat research apply to humans?<\/h3>\n<p>Cancer is a multistage process and requires many \u201chits\u201d as normal cells transform into malignant cells. Thus, the longer a person or animal lives, the more likely cell mutations occur in combination with external factors (exposures to pollution and poor lifestyle habits, for instance) to promote cancer.<\/p>\n<p>One surprising thing about the bat study, the researchers say, is that bats do not have a natural barrier to cancer. Their cells can transform into cancer with only two \u201chits\u201d\u2014and yet because bats possess the other robust tumor-suppressor mechanisms, described above, they survive.<\/p>\n<p>Importantly, the authors confirmed that increased activity of the p53 gene is a good defense against cancer by eliminating cancer or slowing its growth. Several anti-cancer drugs already target p53 activity and more are being studied.<\/p>\n<p>Safely increasing the telomerase enzyme might also be a way to apply their findings to humans with cancer, Seluanov adds, but this was not part of the current study.<\/p>\n<p>Gorbunova and Seluanov co-lead the\u00a0<a href=\"https:\/\/www.urmc.rochester.edu\/university-of-rochester-aging-institute\/research\/roar-center\">Rochester Aging Research Center<\/a>\u00a0at Rochester\u2019s Medical Center. Together, they have built outstanding careers studying the characteristics of long-lived mammals such as naked mole rats and bowhead whales that age well and resist serious diseases.<\/p>\n<p>They also study long-lived humans in collaboration with other institutions, investigating cohorts of people with exceptional longevity to discover which genes and epigenetic factors are overrepresented in these individuals.<\/p>\n<p>The National Institute on Aging supported this research.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Rochester scientists discover that long-lived bats resist cancer thanks to strong immune systems and protective genes\u2014findings that could offer new insights into human aging and disease prevention.<\/p>\n","protected":false},"author":266,"featured_media":656022,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[42472,116],"tags":[13942,18722,18572,16072,10906,16142],"class_list":["post-655922","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-health-medicine","category-sci-tech","tag-aging","tag-department-of-biology","tag-research-finding","tag-school-of-arts-and-sciences","tag-vera-gorbunova","tag-wilmot-cancer-institute"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Why don\u2019t bats get cancer?<\/title>\n<meta name=\"description\" content=\"做厙勛圖 scientists discover that long-lived bats resist cancer due to strong immune systems and genes, offering clues about human aging.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.rochester.edu\/newscenter\/why-dont-bats-get-cancer-655922\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Why don\u2019t bats get cancer?\" \/>\n<meta property=\"og:description\" content=\"做厙勛圖 scientists discover that long-lived bats resist cancer due to strong immune systems and genes, offering clues about human aging.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.rochester.edu\/newscenter\/why-dont-bats-get-cancer-655922\/\" \/>\n<meta property=\"og:site_name\" content=\"News Center\" \/>\n<meta property=\"article:published_time\" content=\"2025-06-10T17:45:34+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2025-11-19T12:58:23+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/www.rochester.edu\/newscenter\/wp-content\/uploads\/2025\/06\/fea-little-brown-bats-1200x630.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"1200\" \/>\n\t<meta property=\"og:image:height\" content=\"630\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"author\" content=\"Leslie Orr\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Leslie Orr\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"3 minutes\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"Article\",\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/why-dont-bats-get-cancer-655922\\\/#article\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/why-dont-bats-get-cancer-655922\\\/\"},\"author\":{\"name\":\"Leslie Orr\",\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/#\\\/schema\\\/person\\\/3f335d3a6fd2ec7b7ed4382cddd27473\"},\"headline\":\"Why don\u2019t bats get cancer?\",\"datePublished\":\"2025-06-10T17:45:34+00:00\",\"dateModified\":\"2025-11-19T12:58:23+00:00\",\"mainEntityOfPage\":{\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/why-dont-bats-get-cancer-655922\\\/\"},\"wordCount\":600,\"image\":{\"@id\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/why-dont-bats-get-cancer-655922\\\/#primaryimage\"},\"thumbnailUrl\":\"https:\\\/\\\/www.rochester.edu\\\/newscenter\\\/wp-content\\\/uploads\\\/2025\\\/06\\\/fea-little-brown-bats.jpg\",\"keywords\":[\"Aging\",\"Department of Biology\",\"research finding\",\"School of Arts and Sciences\",\"Vera Gorbunova\",\"Wilmot Cancer Institute\"],\"articleSection\":[\"Health &amp;
