A Purdue University study\u2019s novel use of an artificial intelligence model has revealed that biological pathways leading to cancer in dogs and humans are more similar than previously known. The research, led by a College of Veterinary Medicine faculty member, demonstrates enhanced value in studying naturally occurring cancer in dogs to learn more about how to defeat cancer in humans.<\/p>\n\n\n\n

The findings, recently published in the journal Frontiers of Oncology<\/a>, also showcase the value of large, accessible databases, such as the National Cancer Institute\u2019s new Integrated Canine Data Commons<\/a> (ICDC), which Purdue is helping to populate.<\/p>\n\n\n\n

In the study led by Dr. Nadia Lanman, research associate professor of comparative pathobiology<\/a>, a model developed at the Frederick National Laboratory was trained using data from The Cancer Genome Atlas<\/a>, a large study of many different types of human tumors, including bladder and brain tumors (gliomas). The model was then used to predict the presence of the same types of cancers in dogs by analyzing cancer sequencing data from dogs with brain or bladder cancer. The results showed that human and canine tumors are similar at the genetic level and that the difference between bladder tumors and brain tumors can be discerned by protein-producing genes. The findings provide added evidence that genetic studies of dog cancer can help us learn more about human cancer.<\/p>\n\n\n

\u201cWe took an AI approach, specifically a deep-learning approach, to probe gene expression profiles of cancers that occur in both humans and dogs,\u201d said Dr. Lanman, who also is a member of the Purdue Institute for Cancer Research (PICR). \u201cWe built two primary tumor classification tools across species. We tested a number of different machine-learning methods and a convolutional neural network called TULIP ended up being the most powerful and accurate approach we tried.\u201d<\/p>\n\n\n\n

A convolutional neural network is an algorithm inspired by the way human brains process visual information. It\u2019s effective at finding and analyzing visual patterns using a large dataset of labeled images. It then trains itself to associate certain patterns or features in the images with specific labels or categories.<\/p>\n\n\n\n

The effectiveness of such technology underlines the importance of databases and emphasizes that the largest datasets get the most robust and reliable results. The ICDC database<\/a> was established to be an ever-expanding dataset capable of advancing research on human cancers through comparative genetic analysis with canine cancer.<\/p>\n\n\n\n

\u201cICDC is a big deal because it\u2019s a place where scientists all over the world can deposit and access data on canine cancer,\u201d said Dr. Deborah Knapp, Purdue Distinguished Professor of Comparative Oncology and the Dolores L. McCall Professor of Comparative Oncology in the College of Veterinary Medicine\u2019s Department of Veterinary Clinical Sciences. Dr. Knapp is one of the study\u2019s co-authors and serves as the director of the Evan and Sue Ann Werling Comparative Oncology Research Center. \u201cResearchers can use ICDC to pull in genetic data from dogs and genetic data from humans and analyze them simultaneously.\u201d Dr. Knapp, a PICR member who also chairs a steering committee for the ICDC, said the database holds great promise for advancing canine and human cancer research. \u201cIt will be serving an even bigger purpose in the future \u2014 to group some cancers by their genetic makeup more so than by the organ in which they started. We are not there yet, but it is definitely a goal we can reach in the future. It\u2019s advancing cancer genetics, which is the most important aspect of this.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
