Patients currently live just 12 to 15 months after diagnosis despite surgery, radiation and chemotherapy.<\/p>\n<p>New <a href=\"https:\/\/www.ucf.edu\/research\/\">research<\/a> led by Kiminobu Sugaya, a stem cell researcher and neuroscientist at UCF\u2019s <a href=\"https:\/\/med.ucf.edu\/biomed\/\">Burnett School of Biomedical Sciences<\/a>, found that targeting a drug resistant mechanism in cancer stem cells significantly enhanced the efficacy of traditional cancer therapies \u2014 making them four times more effective against glioblastoma. Current FDA-approved drugs kill less than 25% of glioblastoma cancer stem cells (CSCs).<\/p>\n<p>These cells are a subpopulation of cancer cells that are highly resistant to current therapies. Scientists theorize that cancer returns and spreads because CSCs remain in the body. That\u2019s why they are exploring ways to kill them outright.<\/p>\n<p>\u201cCancer stem cells are bad stem cells that are programed to become a cancer,\u201d Sugaya says. \u201cThey withstand cancer therapies, raise their ugly head, regrow and metastasize.\u201d<\/p>\n<p>Sugaya\u2019s team developed a new drug delivery system by creating a technology that destroys the RNA, or ribonucleic acid, that the stem cells use as a blueprint to produce proteins. This unique strategy inhibits the expression of embryonic stem cell genes that are pivotal in CSC\u2019s drug resistance. And because embryonic stem cell genes are not expressed in normal adult cells, this breakthrough approach reduces potential for side effects in healthy cells.<\/p>\n<p>Jonhoi Smith is a doctoral student under Sugaya and the first author on their research paper published in the journal <em>Genes<\/em><em>.<\/em> He said the treatment could increase life expectancy for glioblastoma patients.<\/p>\n<p>\u201cThis treatment could be a precious gift for glioblastoma patients. When I think about the loved ones I\u2019ve lost in my life \u2014 my father, my grandmother \u2014 I often wish I could have had more time with them,\u201d he says. \u201cThe idea of offering the potential of a whole new life to people who are facing a death sentence in less than a year means a lot to me.\u201d<\/p>\n<p>One of the significant challenges in treating glioblastoma is effectively delivering treatments to the brain. That\u2019s because the brain is protected from external germs and substances by the blood-brain barrier, which can also prevent treatments from reaching brain tissues.<\/p>\n<p>To overcome this obstacle, Sugaya\u2019s therapy is based on exosomes, nano-sized particles with a lipid membrane that are naturally produced by cells. Exosomes function as cellular communicators, transporting proteins, lipids and genetic material between cells, thereby influencing a wide array of biological processes and functions. Their efficiency in carrying molecules across various parts of the body has inspired scientists to investigate exosomes as potential drug delivery vehicles.<\/p>\n<p>\u201cMany current drug delivery systems, including viruses, may cause side effects,\u201d Sugaya explains. \u201cWe\u2019re using the body\u2019s natural delivery systems and have developed technologies to modify them to carry therapeutic molecules with targeted delivery to specific tissues.\u201d<\/p>\n<p>Marvin Hausman is CEO of Exousia AI, the company that is funding the glioblastoma exosome preclinical research. He heard about Sugaya\u2019s lab and says that when he visited the lab at UCF\u2019s <a href=\"https:\/\/med.ucf.edu\/about\/our-locations\/health-sciences-campus\/\">Academic Health Sciences Campus<\/a> in Lake Nona, he was inspired by its capacity for innovative discoveries.<\/p>\n<p>\u201cI have thoroughly analyzed this exosome-based targeted drug delivery system many times, and the potential that this unique technology offers.\u201d Hausman says. \u201cWe are embarking on a revolutionary new development in medicine.\u201d<\/p>\n<p>Thanks to funding from Exousia AI, the research is advancing to mouse models carrying human glioblastoma, with preliminary results expected as early as this summer.<\/p>\n<p>Sugaya has dedicated more than 40 years to neuroscience research focused on Alzheimer\u2019s disease, with an emphasis on stem cells for the last 26 years. He moved to the U.S. after receiving his doctoral degree from the Science University of Tokyo in 1988. He <a href=\"https:\/\/www.ucf.edu\/faculty\/\">joined UCF as a professor<\/a> in 2004. His cancer research began in 2010 when he discovered stemness gene expressions, the self-renewing and differentiating property that allows stem cells to grow and spread, in CSCs. He is recognized as an expert in the field of exosome research and recently received Florida Innovation Funding from the State Department of Health for his studies.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By targeting a drug resistant mechanism in cancer stem cells, researchers discovered that traditional cancer therapies are four times more effective against glioblastoma.<\/p>\n","protected":false},"author":242,"featured_media":140174,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"lazy_load_responsive_images_disabled":false,"footnotes":"","_links_to":"","_links_to_target":"","_wp_rev_ctl_limit":""},"categories":[12,17,23],"tags":[54254,979,22543,2671,14916],"tu_author":[],"class_list":["post-140173","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-health","category-medicine","category-research","tag-cancer-research-division","tag-college-of-medicine","tag-healthcare","tag-kiminobu-sugaya","tag-research"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.3 (Yoast SEO v27.3) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>UCF Researchers Develop Novel Therapy for Incurable Brain Cancer | University of Central Florida News<\/title>\n<meta name=\"description\" content=\"By targeting a drug resistant mechanism in cancer stem cells, researchers discovered that traditional cancer therapies are four times more effective against glioblastoma.\" \/>\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.ucf.edu\/news\/ucf-researchers-develop-novel-therapy-for-incurable-brain-cancer\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"UCF Researchers Develop Novel Therapy for Incurable Brain Cancer\" \/>\n<meta property=\"og:description\" content=\"By targeting a drug resistant mechanism in cancer stem cells, researchers discovered that traditional cancer therapies are four times more effective against glioblastoma.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.ucf.edu\/news\/ucf-researchers-develop-novel-therapy-for-incurable-brain-cancer\/\" \/>\n<meta property=\"og:site_name\" content=\"University of Central Florida News | UCF Today\" \/>\n<meta property=\"article:publisher\" content=\"https:\/\/www.facebook.com\/UCF\" \/>\n<meta property=\"article:published_time\" content=\"2024-03-12T14:37:33+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2024-03-12T15:02:27+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2024\/03\/Kiminobu-Sugaya_Sugaya-Stem-Cell-Lab.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"1200\" \/>\n\t<meta property=\"og:image:height\" content=\"800\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"author\" content=\"Juzanne Martin\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:creator\" content=\"@UCF\" \/>\n<meta name=\"twitter:site\" content=\"@UCF\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Juzanne Martin\" \/>\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.ucf.edu\\\/news\\\/ucf-researchers-develop-novel-therapy-for-incurable-brain-cancer\\\/#article\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/www.ucf.edu\\\/news\\\/ucf-researchers-develop-novel-therapy-for-incurable-brain-cancer\\\/\"},\"author\":{\"name\":\"Juzanne Martin\",\"@id\":\"https:\\\/\\\/www.ucf.edu\\\/news\\\/#\\\/schema\\\/person\\\/85cf3bab26b268af0b080375c968e4c7\"},\"headline\":\"UCF Researchers Develop Novel Therapy for Incurable Brain Cancer\",\"datePublished\":\"2024-03-12T14:37:33+00:00\",\"dateModified\":\"2024-03-12T15:02:27+00:00\",\"mainEntityOfPage\":{\"@id\":\"https:\\\/\\\/www.ucf.edu\\\/news\\\/ucf-researchers-develop-novel-therapy-for-incurable-brain-cancer\\\/\"},\"wordCount\":698,\"image\":{\"@id\":\"https:\\\/\\\/www.ucf.edu\\\/news\\\/ucf-researchers-develop-novel-therapy-for-incurable-brain-cancer\\\/#primaryimage\"},\"thumbnailUrl\":\"https:\\\/\\\/www.ucf.edu\\\/wp-content\\\/blogs.dir\\\/20\\\/files\\\/2024\\\/03\\\/Kiminobu-Sugaya_Sugaya-Stem-Cell-Lab.jpg\",\"keywords\":[\"Cancer Research Division\",\"College of Medicine\",\"Healthcare\",\"Kiminobu Sugaya\",\"Research\"],\"articleSection\":[\"Health &amp;
