To overcome this, our latest research introduces a breakthrough in \"deep plasma proteomics,\" utilizing a specialized technique to filter blood plasma and detect over 6,400 proteins\u2014an unprecedented depth that allows us to see molecular details that were previously hidden. By analyzing these comprehensive protein signatures, we successfully solved a critical clinical puzzle: distinguishing the biological \"footprint\" of the disease\u2019s natural progression from the changes merely caused by dopaminergic medications. We took this a step further by integrating our findings with functional genomic screens, linking these blood-based signals directly to the cellular mechanisms driving neurodegeneration in the brain. This systems-level approach not only validated robust biomarkers for tracking patient health but also identified \"druggable\" targets that are already addressed by existing medications, paving the way for a new era of precision medicine where a simple blood draw can guide personalized therapeutic strategies.<\/span><\/p><p class=\"c1\"><span style=\"overflow: hidden; display: inline-block; margin: 0.00px 0.00px; border: 0.00px solid #000000; transform: rotate(0.00rad) translateZ(0px); -webkit-transform: rotate(0.00rad) translateZ(0px); width: 720.00px; height: 268.00px;\"><img decoding=\"async\" alt=\"\" src=\"https:\/\/kimlab.us\/wp-admin\/admin-ajax.php?action=research_image_proxy&amp;url=https%3A%2F%2Fdocs.google.com%2Fdocs-images-rt%2FALKuztZoidafbBdlINR7amS7-J9jJpa0XuYCeLv5zmHmcABsGygKEQN9vRU4My4zCQt6bq05xz7CTIRNShc5-21OTuEjU7JUZpgNYPDhzRCz8fZNuqVD6CXPzY2PPEFjDaZl_hzzs1fBv9_ad1VHX2JL%3Ds2048\" style=\"width: 720.00px; height: 268.00px; margin-left: 0.00px; margin-top: 0.00px; transform: rotate(0.00rad) translateZ(0px); -webkit-transform: rotate(0.00rad) translateZ(0px);\" title=\"\"><\/img><\/span><\/p><p class=\"c5\"><span style=\"overflow: hidden; display: inline-block; margin: 0.00px 0.00px; border: 0.00px solid #000000; transform: rotate(0.00rad) translateZ(0px); -webkit-transform: rotate(0.00rad) translateZ(0px); width: 458.50px; height: 313.01px;\"><img decoding=\"async\" alt=\"\" src=\"https:\/\/kimlab.us\/wp-admin\/admin-ajax.php?action=research_image_proxy&amp;url=https%3A%2F%2Fdocs.google.com%2Fdocs-images-rt%2FALKuztZnOugqic68OZX3FBnJIaZpPetaQd08yab_cQom8BduN2HNsk0DM53Dgch7X3jOXoHTuShgzgZxWYLHL2uuwUVD79lHfS4xjOtOuTHK0qGK_eY1qUhNHAMRXCLOtP2zjk5rk1tLPLqKwHDvZmZM%3Ds2048\" style=\"width: 458.50px; height: 313.01px; margin-left: 0.00px; margin-top: 0.00px; transform: rotate(0.00rad) translateZ(0px); -webkit-transform: rotate(0.00rad) translateZ(0px);\" title=\"\"><\/img><\/span><\/p><p class=\"c1 c4\"><span class=\"c0\"><\/span><\/p><p class=\"c1\"><span class=\"c2\">Mapping the Hidden \"Postal System\" of Cellular Communication via Applying Functional Genomics on Extracellular Vesicles (EVs)<\/span><\/p><p class=\"c1\"><span class=\"c0\">Cellular communication relies heavily on the exchange of extracellular vesicles (EVs)\u2014tiny biological packages that ferry information between cells\u2014but this process is frequently exploited by cancers to drive tumor progression. To decipher the genetic rules governing this hidden communication network, we developed a trio of novel functional genomics platforms: BOGO-EV and CIRCUS to track how vesicles are manufactured, and a \"Trojan horse\" system called TAMER to determine how they are absorbed. By identifying these specific bottlenecks, our study establishes a new blueprint for precision medicine, demonstrating that pharmacological inhibitors can target these proteins to break the pathological communication loops that fuel disease.<\/span><\/p><p class=\"c5\"><span style=\"overflow: hidden; display: inline-block; margin: 0.00px 0.00px; border: 0.00px solid #000000; transform: rotate(0.00rad) translateZ(0px); -webkit-transform: rotate(0.00rad) translateZ(0px); width: 563.50px; height: 291.92px;\"><img decoding=\"async\" alt=\"\" src=\"https:\/\/kimlab.us\/wp-admin\/admin-ajax.php?action=research_image_proxy&amp;url=https%3A%2F%2Fdocs.google.com%2Fdocs-images-rt%2FALKuztZthqxeK_jVYDeTUoK35ki88q9IBqZPURRbxGpINOLKHE5HMkfdgbZg2jvUGJ9kck7kUyWnsImwHuTTN-KfOxxj8cNt-Og1T_NBmFHNw31qHIcoPzZGdD3BENgjFsGNj8cK13xQXWiVa4XSDg%3Ds2048\" style=\"width: 563.50px; height: 291.92px; margin-left: 0.00px; margin-top: 0.00px; transform: rotate(0.00rad) translateZ(0px); -webkit-transform: rotate(0.00rad) translateZ(0px);\" title=\"\"><\/img><\/span><\/p><p class=\"c1 c4\"><span class=\"c0\"><\/span><\/p><p class=\"c1\"><span class=\"c2\">Exploring disease mutants that cause a gain of protein-protein interactions<\/span><\/p><p class=\"c1\"><span class=\"c8\">Mutations rewiring PPI networks are known to be important in cancer<\/span><span class=\"c6\"><a class=\"c7\" href=\"https:\/\/www.google.com\/url?q=https:\/\/paperpile.com\/c\/HFd1RF\/UHZeh&amp;sa=D&amp;source=editors&amp;ust=1792929672580027&amp;usg=AOvVaw2PUZGIyLNhfDfyUM8MQY1_\">(Bowler et al., 2015)<\/a><\/span><span class=\"c0\">and other diseases.
